Goals of Research Papers in Psychology

When psychologists write a research paper in “the real world”, our intention is usually to submit the paper to a journal so that it may be evaluated for possible publication in the journal.After we have gone to the trouble of collecting and analyzing our data, we want to tell as many people as possible about it, and ensure that the right people see it.By “the right people”, I mean the people that we know do similar research, and who are the most likely to appreciate the work.Publication in a journal is the primary means of describing our research and distributing it to a wider audience.

Make the paper interesting to the reader.Now, we all know that some people simply don’t have any interest or expertise in your paper topic, and no matter what we do to make it interesting, those people won’t read it.Also, we know that people who do work related to your topic will already be interested in your topic, and those people will read your paper no matter what.The most important group, however, consists of the people who might read your paper if you do a good job of making it interesting, but who might move on to the next paper if you don’t.These are the people that you want to “grab”.If you do a really good job of making the paper interesting, you might even convince people who don’t think they are interested in your work that they should read your paper.

How to generate interest?Ultimately, you need to convince people they should be interested in your paper.One way of doing this is to demonstrate that the work is relevant to them in some way.A time-honored tactic for doing this is to describe how the cognitive or perceptual process you’re studying might get used in the everyday world.Is this something that happens to everybody?If so, when?Is it something that happens only under certain circumstances or to certain people?The conditions that you used in your experiment might occur, for example, when one turns out the lights before going to bed.They might occur to firefighters trying to navigate through a smoky building.They might occur for airline pilots under a high workload situation.They may occur to everybody as they walk from outdoors in sunlight to indoors under fluorescent lights; they might occur as we try to interpret black and white photographs.It may take some creativity on your part to think of a situation in real life that draws upon the cognitive or perceptual process you’re studying, but it’s a crucial part of writing research papers.One way to get some inspiration is to see what other authors write about in the first paragraph of their papers.Many of them will start off with this kind of comment.Another way to get inspiration is to think about how you would describe your topic to your grandparents.

Use proper APA format.Why does APA style have so many nit-picky requirements, and why do you have to learn them?APA style is designed to standardize the format of papers that get submitted for review for possible publication in a journal.Standardization is important for several reasons.

(1) Standardization means that papers won’t get unfairly accepted or rejected for publication simply because they use a more (or less) attractive font size or heading style or whatever.If you’ve ever submitted a resume, you’ve probably wondered whether other people’s resumes might have an edge over yours just because they “look” better visually.APA style is designed to remove that possible factor, and that’s a good thing.

(2)Standardization translates into more efficient reviewing.I get asked by journal editors to review 3 – 4 manuscripts per month sometimes, and this is not at all uncommon.If all the manuscripts have the same format, reviewers will know exactly what to look for at exactly the same place in every manuscript.This can be a HUGE time-saver for people who do a lot of reviewing.

(3)Standardization also translates into more efficient reading and researching.Scientists must read many papers every month to keep up with the latest developments.If all the papers have the same format, it is much easier to digest the information, because you don’t have to hunt for the information you need.Think about going to a familiar grocery store versus going to an unfamiliar grocery store.You’ll get out faster if you know where to find the things you need.

Write for the appropriate audience.In papers for this class, assume that you are writing for an educated audience that is not familiar with your particular topic.This means that you can assume readers are familiar with basic concepts like retinal disparity, response time, independent variable, mean and standard deviation, and so forth.You will need to define more specialized terms like “specific distance tendency”.

Writing for an educated audience that is unfamiliar with your topic is actually a good rule of thumb to follow even if you are writing a paper to submit to a journal, for a couple of reasons:(1) If your paper is understandable even for people who are not familiar with your particular topic, this means it will be easier to understand for people who ARE familiar with your topic.(2) The reviewers or editors who are making decisions about whether or not to accept your paper for publication may not be specialists in your field.If your paper is understandable to non-specialists, this increases the chances that your paper will be accepted.

Present ideas clearly.There should be a clear, logical flow of ideas in each section of a research report in psychology.This is particularly important in the Introduction and Discussion sections.Does the flow of your ideas make sense?Here are some tips for creating clear, logical reports.

·Make an outline.As is discussed below (“Writing the Research Report”), before beginning to write, it is crucial to make a detailed outline first.This will help you organize your ideas before committing anything to paper, and this organization will come through in the words you eventually write.

·Make the structure obvious.One way to help the reader follow the flow of your ideas is to provide some foreshadowing for what topics you are going to cover.For example, after introducing your topic in the Introduction section, you might include several sentences like, “First, this paper will review some of the most relevant findings in the existing literature.Then, it will discuss some limitations of past work, and introduce an experiment designed to address these limitations.”It may initially seem odd to be so explicit about the framework of your paper, but in scientific writing, this kind of technique is a good idea, because it helps the reader follow the logic of your paper.

·Create logical paragraphs.Paragraphs should have a beginning, middle, and end.The beginning of any paragraph should introduce the topic to be discussed in the paragraph.This could include a transitional comment that links the ideas from the previous paragraph with the upcoming material.The middle of the paragraph contains the actual discussion of the topic.Finally, the end of the paragraph should summarize or conclude the discussion.

Stages in the Research, Thinking, and Drafting Process

Conducting research and describing the results follows several distinct stages:(1) Selecting a general topic; (2) Finding previous research related to the topic; (3) Developing a specific research question; (4) Creating an experimental design; (5) Collecting and analyzing data; and finally (6) Writing the research report.Here, we will go into each of these stages in more detail.

1.Selecting a general topic

When you are new to a certain field of research, it can be difficult to come up with a research topic.You know very little about the field, so where to begin?

Lectures:if there has been something in a lecture earlier in the semester that caught your attention, brainstorm about that topic to see if you can turn that interest into an experiment.

Flip through the textbook:Some pictures or demonstrations may catch your eye.You could try going to the library to find other, similar textbooks.There also may be other books near that section that catch your eye.

Newspaper, magazine articles, emails:again, think about things that really “grabbed” you recently.Ask yourself what about the topic grabbed you, and think about what kind of cognitive or perceptual processes might be involved.

Hobbies:if you’re good at music, art, sports, video games, or something else, each of these pursuits requires a wide range of perceptual and cognitive processes.You can potentially get inspiration from thinking about what you like in your hobby, and then thinking of an experiment that might help you understand something about your hobby.

Remember that your topic should be fundamentally about visual perception.It can be a challenge to decide if your topic is really about visual perception, because there are so many things that involve vision.

NOTE:you will get a handout that describes the Final Project assignment in more detail.

NOTE:see Appendix C for a list of resources that are available for Final Project Experiments.

Unacceptable topics:

The effect of drugs / alcohol on __________.(obvious reasons!)

The effect of gender on ________ (typically, there aren’t enough men in class to do this)

How much change in the amount of sugar in a drink does it take for people to tell that more sugar has been added?(this does not involve visual perception)

Do children have different contrast sensitivities than young adults?(can’t do research involving people outside of your lab section)

Effect of soothing / loud music on ability to learn words presented on a screen (you are seeing the words, but experiment is more about hearing or attention)

Do people remember words better if are associated with a disgusting / sexy / scary image?(again, you’re seeing words and pictures, but experiment is more about memory than vision)

2.Finding previous research related to your topic

1.Textbooks:First, check to see if the textbook mentions the topic you are interested in.If it does, you may be able to find references to papers published on the topic.Also, you can use textbooks to get ideas about what keywords you could use when doing an on-line search.

2.Perception Handbooks:Another source for general information about topics in visual perception (and potential sources for published research) is to look for a perception handbook.These books have short articles on a wide variety of topics, much like an encyclopedia, but handbooks are a bit more in-depth and scholarly.On the main Gelman Library page (, type in “handbook perception” in the “ALADIN Catalog Quick Search” bar at the top of the screen, and be sure “keyword” is selected under “more search options”.This will yield a lot of handbooks to choose from.You will need to physically go to the library to look at these handbooks, but browsing through them is sure to give you some ideas, and will likely give you some leads on research articles.

3.On-line database searches.Perhaps the most helpful thing for finding articles related to your topic is to do an on-line database search through Gelman Library’s ALADIN site.This is described in detail in Appendix B.One of the biggest challenges in doing this kind of search is knowing what keywords to use.Simply putting in “visual perception” as a keyword search is a complete waste of time, because you will get a kazillion unhelpful hits.You can get inspiration for more specific keywords from textbooks or handbooks.If you have already found at least one article related to your topic, you could try entering words or phrases from the article title or abstract as keywords.Note that some articles actually provide keywords for you.

4.Internet searches.Finally, as a last resort, you could try doing a search using an internet search engine like or kind of search should only be used as a means of thinking of appropriate keywords or getting ideas during the initial stages of selecting a topic.It should not be used as a primary means of researching your topic.

3.Developing a Specific Research Question

Once you have settled on a topic, you should develop a specific research question.A research question is the question your experiment is designed to answer.It should be a single sentence, phrased as a question, that captures the question your experiment is designed to answer.For example, “How do ____ and _____ affect our perception of _____?”Or:“Can this phenomenon be explained by ________?”“Does this phenomenon still occur when we use _____ instead of _______?”One you have your research question ready, you will be ready to move on to the next step.

4.Creating an Experimental Design

This is something that is something that entire semester-long classes are taught on, so we can only provide the bare essentials, here.The “design” specifies exactly what conditions you will be presenting and what kind of task you are asking subjects to perform.Your TA can give you some advice about how to design an experiment to address your research question, but here are some questions you should try to answer on your own first:

·What is your research question?Make it as specific as possible.

·What are your predictions?

·Can you use the same design as a previous experiment?

·Will you need to divide subjects into separate groups, or can each subject be exposed to multiple different conditions?

·What are your independent variables?(what are you manipulating or varying?)In this class, you should have two independent variables (IV); each IV should have 2 to 3 levels.

·How will subjects respond?What is their task?

·How will you record subjects’ responses?

·Will you collect multiple measurements for each condition?

·How many trials will there be for each subject?

5.Collecting and Analyzing the Data

Once you have settled on a design, you will need to make all the necessary preparations for running your experiment.You will then collect your data during one of the two lab sessions set aside for the final project experiments.In this class, we do not use inferential statistics (ANOVA, T tests), but we do use descriptive statistics to help us compare the data.Usually, but not always, your descriptive statistics will include the class mean and standard deviation for each of the conditions you tested.So, for example, if you have 2 IV’s, each with 3 levels, you should report 6 sets of means (2 x 3) and 6 sets of standard deviations.

6.Writing the Research Report

Start Early.People who do a lot of writing agree that time is one of the most important factors in producing a good paper.You must start writing soon enough before the deadline that you have time to organize your thoughts, do a literature review, write the paper, and spend time revising and polishing.At a bare minimum, allow yourself a single day for each one of these steps.Ideally, you would spend more than a single day writing!But the point is that you should leave enough time that you can finish a draft of the paper, sleep on it, and come back to do the revising and polishing the next day.This will dramatically improve your final product, but you must plan ahead.

Make an Outline.Before actually starting on the paper, it is absolutely imperative that you make an outline first.The reason outlines are so important is that they shorten the overall amount of time it takes to complete the paper.Think about it:If you write an outline first, it makes you organize the ideas and logic of your paper and helps you identify and iron out difficult issues before you commit any words to paper.Then when you start writing, most of the hard issues have already been fixed. However, if you start writing without an outline, you run the risk of writing hundreds of words before realizing that what you’ve written will never work.Then you’ll have to start over, and this increases the total time you have to spend writing.So, if you want to minimize the amount of time you spend writing, you must make an outline first.

What should be in the outline?You should lay out the ideas in your first paragraph, in order.Then, you should lay out how you will describe previous research.What topics or theories will you cover?What terms will you need to define, and when will you define them?What specific papers will you discuss?What remains unknown about your topic?After outlining your discussion of previous work, you should lay out how you’ll introduce your own work:what is your research question?What are your hypotheses or predictions?

Get Motivated to Write.If you don’t feel like writing a paper, this can be a significant obstacle to getting it done.Even professional, full-time researchers go through times when they don’t feel like sitting down to write.The trick is NOT to force yourself to write when you don’t want to.Instead, you should think of ways that make you genuinely WANT to write.As you gain experience, you will start to develop a bag of tricks that reliably make you feel like writing.Ideally, your bag of tricks will get so big and so varied that you will always be in control of your motivation to write.If you need to write, you can reliably sit down and get it done.

·Find a time of day:The ability to focus and get work done varies across the day for most people.What times of day are most productive for you?

·Listen to music:Listening to favorite music or watching clips from a movie can help.

·Reward yourself:promising yourself a reward after spending a couple hours of writing can be very effective.

·Think about finishing:If writing feels like hitting yourself on the head with a hammer, think about how good it will feel when you stop!Thinking about getting a project off your plate can be an extremely powerful motivator.

·Think about a hero:We all know people who impress us with their ability to focus and attain their goals.This might be a musician, author, athlete, actor, family member, religious figure, or a professional in your chosen field.For many of us, writing papers is a way to attain our goals—whether it’s passing a class, graduating college, getting a promotion, or whatever.Putting yourself in the shoes of someone you admire can be a very powerful motivator.

·Write a few sentences:The first few sentences are always the hardest!Go ahead and write a couple of sentences, without worrying about whether they are any good.Getting over this hurdle can sometimes get the ball rolling.

General Writing Tips and Reminders:

·Effect vs. Affect:These are both real words that are used frequently in psychology, but they have different meanings.It is very easy to use them incorrectly without realizing it, because they sound so similar.This means that every single time you use one of these words, look closely to be sure you are using the word correctly.In most cases, “effect” is a noun; “affect” is a verb.For example:What is the EFFECT of turning off the lights?And:Does during out the lights AFFECT responses?

·“Proves”:Psychologists are very reluctant to use the word “proves” in scientific writing.It suggests there is absolutely no doubt about the results of an experiment.Very few experiments in the history of psychology are completely beyond doubt.This being the case, you should make it a habit to avoid using the word “proves”.Instead, you can say “the results strongly suggest that…” or “the results indicate that…” or “the results show that…”.

·Use IV / DV properly.The Independent Variable (IV) is something the experimenter manipulates, or varies, in an experiment, to see what effect this has on the participant’s responses.The Dependent Variable (DV) is the thing that is measured in a study.In psychology experiments, the DV will often be something like Response Time, number of errors, percentage of correct responses, magnitude estimation, or some kind of matching response.

·Avoid sentence fragments.Every sentence should have a subject and a verb.Do not begin a sentence with a conjunction like “and”, “but” or “yet”.Starting with a conjunction automatically create a sentence fragment even if the fragment has a subject and a verb.

·Use semicolons properly.The phrase after the semicolon should be a complete sentence that could stand on its own as a sentence if you took away the phrase before the semicolon.Avoid using too many semicolons:a good rule of thumb is no more than one semicolon per page.

·Use correct verb tense.Events that have already occurred — history, procedure, results — should be described in the past tense.For example, “Smith and Wesson found …”; “The subjects were instructed …”.This specifically applies to all report sections with the exception of the Discussion.

·Avoid using first person singular.Research reports should be impersonal and objective.Thus, you should avoid using “I” or “we”.Rather than saying “I told the subjects…”, you should say “The experimenter told the subjects…” or “The subjects were told….”

·Write as if report is a professional manuscript being submitted for publication.Therefore, you should speak of an “experimenter and subjects” rather than a “lab instructor and students”.

·“Experimenter” is spelled with “-er”

·It’s / Its:

“It’s” is a contraction and means “it is” or “it has”.EX:It’s lunchtime already.

–You should never use contractions in an APA-Style paper!

“Its” is the possessive form of “It”.EX:Participants turned on the computer and its monitor.

·“Dependent” is spelled with “-ent”

·“Stimulus” is singular; “stimuli” is plural:

“These stimuli were presented twice apiece.”

“This stimulus was presented twice.”

·“Data” is plural:“This data supports our hypothesis”: INCORRECT!

“These data support our hypothesis”:CORRECT

Writing the Abstract

The GOAL of an abstract is to convey why you did your experiment, what general methods you used, what were the results, and how you interpret the results.The challenge, of course, is to do all this in a very small number of words.One strategy is to start off by devoting a single sentence to each of the following sections:

·Why did you do this experiment? (What research question did you attempt to answer?)

·General method (What did you manipulate?What was the subject’s task?)

·Results (Don’t include numbers or statistics; were your predictions supported?)


This will take a lot of condensing and summarizing, obviously.Once you have your four sentences, see how many words they contain.You will probably have some additional words you could add.Take a look at what you have written and decide where it would help to add another sentence of explanation.Often, it will require more than one sentence to summarize adequately why you did the experiment or what methods you used.

You should also be aware that for many people, the quality of your abstract will determine whether or not they read your paper at all.Thus, ideally, the abstract should convey something of the importance of your work and convince readers that they should read the whole paper.You may not have enough space to say much about this, but it should always be in the back of your mind.

Writing the Introduction

The overall GOAL of the introduction is to tell readers why you conducted the experiment, give them enough background information to understand the topic you are studying, and convince them that it’s important.There are three basic parts of a good Introduction section:(1) Introduce the general topic; (2) Describe past research related to your topic; and (3) Describe the experiment you conducted.Here is a closer look at each of these steps:

1.Introduce the general topic:1 – 2 paragraphs

The first paragraph of your paper is important for “grabbing” the reader.(See “How to Generate Interest”, above.)You may want to consider the following:

·Begin with a general observation about the world that relates to your topic.

·Or, begin with a real-life situation that is difficult for people because they make the kind of errors you’re interested in.

·Or, begin with a real-life situation in which people use the cognitive or perceptual process you’re studying.

·Next, point out how these general observations relate to a more fundamental cognitive or perceptual process.

·Give some indication of what we still don’t understand about the cognitive or perceptual process you’re studying.In some cases, this will be a good place to state your specific research question.In other cases, you will need to provide more background information before your question will make sense.In either case, be sure to make it clear that your goal in the paper is to investigate either the general topic, or your specific research question.

·If you use any specialized terminology in the first paragraph, provide a brief definition.

·Close the first paragraph with a sentence or two describing why this phenomenon is important.These sentences should be your best argument for why readers should be interested in your topic.For example, if you have already shown that people use this cognitive / perceptual process every day or in important situations, you can point out that studying this process will lead to a better understanding of how people do __________ in their everyday lives.

2.Describe past research related to your topic

In the first paragraph, you introduced your topic in general terms.In the next few paragraphs, you should become very specific about your research question.Include the following information:

·If you have not already stated your research question, do so as soon as possible after the first paragraph.Provide background information as needed.

·Be sure to define all specialized terminology.

·Provide citations for any ideas that are not your own (see “Citing Previous Work”, below); use correct APA citation style.

·What is known about your topic?

·What theories have been suggested to explain your phenomenon?

·What aspects of these theories have been tested before?

·How were these theories tested?(what methods were used?)

·What remains unknown about the topic?

Where should you state your research question?Sometimes, your first paragraph will do a good job introducing your topic, and you can state your research question in the first or second paragraph.After stating your question, you will launch into what is known about your question, what theories have been suggested, etc.Other times, you will need to provide a little more background information about past experiments before your specific research question will make sense.If you need to provide background information first, it’s OK to do that.In general, however, a good rule of thumb is to give your research question in the first or second paragraph.

3.Describe your experiment

After describing past experiments and stating what remains unknown, you are in a good position to describe your own experiment.Consider the following:

·How does your study differ from those that have been done in the past?

·What new knowledge will be gained by using your methods?In Psy 106, our studies will often simply replicate past experiments with different methods.In this case, the new knowledge might be showing that your phenomenon holds true even when different methods are used.

·Based on theories of the topic and past research, what is your hypothesis about what explains your phenomenon?

·BRIEFLY summarize what methods you will use to test your hypothesis.What will you vary?What kind of task will people perform?It is important to keep this summary brief:shoot for 2 – 3 sentences, at most.

·Based on your hypothesis and your design, what results do you expect from your experiment?

Writing the Method Section

The GOAL of the Method section is to provide all the information needed for another researcher to replicate your experiment.The Method section is relatively straightforward.APA Style specifies what sections should be included, so those guidelines should be followed (Participants, Apparatus, Procedure, etc.). Also, this section will include lots of demographic information and measurements, so be sure to check the proper APA format for reporting that information.

If you are new to writing Method sections, one of the most challenging things is to know how much detail to provide.It is important to be complete, but if you include too much detail, the Method section will be wordy and difficult to follow.Your goal, then, is to provide only the important information, without including unnecessary details.In general, more detail is needed for apparatus unique to your experiment; less detail is needed for standard materials your reader will be familiar with.

Information that is necessary:

·Who were the participants?(# of males / females; average age; age range; were they students?)

·What was the participants’ motivation (course credit? monetary payment?)

·If subjects were paid in exchange for participating, how much were they paid?

·The variables you are manipulating (Independent Variables) and how you are measuring participants’ responses (Dependent Variable).

·The crucial pieces of equipment and materials used in your experiment

·The crucial steps involved in actually running the experiment

·What information was given to the participants regarding their task?Use block quotes to include specific instructions if it is important to the experiment.

Information that is typically NOT necessary:

·Name of the university or city where students were enrolled

·Name or number of the specific course in which students were enrolled

·Dimensions of sheets of paper used for responses

·What type of writing utensil was used, if responses involved writing

·Non-crucial procedural details (for example, “Participants were greeted and handed a sheet of paper.”)

Writing the Results Section

The GOAL of the Results section is to report the data you collected.Your top priority should be describing the data clearly, and in a way that is effective in showing your reader why it is important.In this class, we do not use inferential statistics (ANOVA, T tests), but we do use descriptive statistics to help us compare the data.Usually, but not always, the descriptive statistics will include the class mean and standard deviation.Be sure to check the proper APA format for reporting numbers and referring to any tables or figures you are including in your paper.

·Report all statistics in a way that makes it clear how each group performed.For example:“The Reversal Group had a mean errors-to-criterion score of 13.2 with a standard deviation of 1.4.The Standard Group had a mean errors-to-criterion score of 8.5 with a standard deviation of 0.6.”This format may appear repetitive, but in the Results section, clarity is more important than elegance when presenting data.

·Include comparisons of all the data that you report and any trends you find.For example:“There was a difference of 4.7 errors between groups, with the Reversal Group having more errors than the Standard Group.”

·DO NOT include any interpretations in the Results section.The Discussion section is where you interpret what your data mean and how your findings relate to your predictions.

·Prepare any figures and tables so that they are understandable without accompanying explanations.This means that for most reports, your data will appear both in the text of your Results section and in an accompanying figure.Tip:before finalizing your figure or table, try thinking of several alternative ways of presenting the data, and then choose style of presentation that you think will be most striking, most clear, or most compelling.

·Always refer to your figure or table in the Results section.For example:“Mean responses and standard deviations were calculated for both groups to aid comparisons (see Figure 1)”.

Writing the Discussion Section

The GOAL of the Discussion section is to interpret the data presented in the Results section and examine whether or not the hypotheses stated in the Introduction were supported.


Writing a Lab Report in Psychology
(printable version here)
by Melanie Cooke, Tori Giaimo and Athena Hensel

Lab reports are a critical aspect of learning to write in psychology, and comprise a large part of the Intro to Psychology lab grade at Richmond. Although they may seem overwhelming to you now, lab reports can be written efficiently and effectively if you follow a formula that optimizes clarity and concision. It's important for you to learn how to write a lab report early on in your psychology studies; psychology isn't just about studying the human mind and its functions, but also about communicating what you've studied. Ultimately, you want to make a contribution to the field of psychology, whether it be a report for an introductory psychology course or groundbreaking research that will be published in a prestigious scholarly journal. It all begins with the lab report.

The Student-Teaching Fellow Relationship

Up until now, your assignments have been graded primarily by your professor. In contrast to this traditional evaluation, psychology lab reports in Intro to Psychology are graded by teaching fellows - upper-level undergraduates who are majoring in psychology. This type of grading allows students to become familiar with peer review. Peer review is a practice in which scholars review the writing of their colleagues (or peers) in a particular field of science or literature. In this case, teaching fellows (TF's), peers of Intro Psychology students who have extensive knowledge in the subject of psychology, review the lab reports and provide constructive feedback.

In an effort to preserve objectivity, both teaching fellows and students must act with discretion. To maintain anonymity when being graded by your teaching fellow, be sure to use your University ID ( in substitution of your name) in lab reports, particularly on the title page. Also, remember to write out the honor code and sign it with your University ID. Teaching fellows attribute lab report grades to your University ID instead of your name and are not allowed to associate your ID number with your name.

APA Format for Lab Reports

In many disciplines, professors may discourage the adoption of a single template for writing assignments. However, in psychology, formal papers are usually required to follow APA format. Below is an overview of how to specifically format lab reports for Intro to Psychology lab classes, but a more in-depth discussion of formatting papers in APA style is located here. The lab report follows the same basic "hourglass" structure as an empirical journal article (without the abstract):

    1. Title Page
    2. Introduction
    3. Methods
    4. Results
    5. Discussion
    6. References
    7. Appendix/Tables and Figures
You can also reference this template for Intro to Psychology lab reports.

Title Page

  • The header on the top-left of your title page should read "Running head: (ABBREVIATED TITLE OF LAB REPORT)." The words "Running head" should appear exactly as it does here, with only the first letter capitalized. The words "Running head" should only appear on the title page. Every other page should only have the compact form of the title of the report, with all letters capitalized, as the header in the top-left corner.
  • In the top-right corner of each page, with the exception of the title page, include the page number (beginning with "2"). According to APA style, all type should be in Times New Roman 12 pt. font.


  • Your title should consist of four lines in the center of the page.
  • The first line should be the title of your lab report. Titles should be simple and informative. You can use the template "The Effect of the IV (independent variable) on the DV (dependent variable)." Your title, however, should not be in quotation marks.
  • The second line should be your University ID number.
  • The third line should state your institution - the University of Richmond.
  • Finally, the fourth line should state the week day and time of your lab. Your name should not appear on the title page or anywhere in your lab report.


Review of Background Literature
  • Following the hourglass shape, your first section should begin very broadly by introducing basic concepts and previous research that relate to your study.
  • Briefly describe the studies or experiments in the past research, noting the procedures, results, and, most importantly, how it relates to your own laboratory study (for example, explain how your study could further develop the theories supported or observations recorded in a previous study). If you are having trouble connecting past research to your current study, think about the questions the past study raises. Is your study attempting to answer one of them?

Defining Theories and Terms

  • You should also introduce and define any theories or terms that an intelligent layperson (someone not familiar with the field of psychology) would not automatically know.
  • These terms include the ones in your textbook, as well as the theories/terms discussed in class. Because your study is providing either support for or opposition to a theory in psychology, you must inform the reader of that particular theory.
  • Refer to your textbook for definitions of specific terms, but always remember to cite!


  • The introduction in your lab report should end with your hypothesis, which acts as your thesis statement for the paper.
  • The purpose of the introduction is to "introduce" your hypothesis gradually, going from general psychological processes or theories to the specific assumption you are trying to put forth (this creates the top of the "hourglass").
  • A well-written introduction should be a "roadmap" to your hypothesis- the reader should be able to get to your hypothesis and think "well of course that's what they were going to study!



  • Discusses the participant group of your study.
  • Include the number of participants, and demographic information that is relevant to your study, including age, gender, ethnicity/race, and geographical location.
  • Show these demographics as percentages or ratios instead of describing every individual; do not include specific names.
  • Remember that for most lab write-ups, you and your Psych 100 classmates are the participants, so mention that your participants received class credit for participating.


  • The procedure describes how you performed the study. Be specific and exact, so that others could possibly replicate your study procedure if they wanted to re-test your findings.
  • Write the section in paragraph form, not as a list of steps.
  • Remember to identify the independent and dependent variable(s), and to give a sample question if a questionnaire was used.
  • Remember to mention that participants gave their informed consent and were debriefed at the study's end.


  • Here is where you state the results of your study.
  • Specify what statistical test you used to calculate results, as well as the quantitative results (see the APA format page to look up how to cite statistics in APA format.)
  • Mention whether or not there was a statistical difference, if your class calculated it.
  • DO NOT interpret your results in this section: that comes in the Discussion section.


Your Discussion section should contain five main parts. They do not need to be written necessarily in the following order, but you should try to devote at least a paragraph to each point.

  • You should always begin your discussion by reiterating your original hypothesis, and state whether or not your results supported the hypothesis.
  • You can go into some detail here; for instance if your results did not support the hypothesis but instead displayed a different pattern, you should discuss what you actually found.
  • NEVER say your results "proved" your hypothesis or a theory. In science we can't ever prove a theory correct (but we can disprove a theory by giving enough opposing evidence).

Previous Research

  • Whether your results supported the hypothesis or not, refer back to previous research and compare your results to theirs.
  • Keep in mind the differences between your methodology and that of other researchers!
  • What does your study contribute to the pre-existing literature on your topic?


  • Discuss what aspects of your study design and procedure could have been improved to get better results, while still testing the same variables.
  • Some questions to keep in mind when assessing limitations:
    • Were your operational definitions precise? That is, did the variables you tested really reflect the psychological process you want to study?
    • Was your procedure consistent across conditions?
    • Was there some aspect of the participant group that could have skewed results? (For instance, would having an all-female, or all first-year participant group influence findings?)
    • Did the TF/researcher give clear directions for how to perform the experiment?
  • Don't just list your limitations: also discuss how they could be fixed in the future.

Future Research

  • In this section, you should discuss the "what now" aspect of your experiment. You should propose some suggestions for future research on your topic.
  • Suggestions should not just fix the limitations you've discussed in the previous section. Rather, just as you thought about the questions raised in previous studies, think about the questions that went unanswered in your study.
  • For instance, what would be the effect of changing one of your variables?


  • By now, you've made it to the bottom of the hourglass: your discussion should then focus on the impact of your results on the "real world." We encourage you to be creative here, because what's the point of doing research if you can't use the results anywhere?
  • How do your results relate to individual people like you or me?
  • How could they be used to solve problems in the community?
  • How could these results be applied to things like legislative policy or education?


  • Your reference page includes all the sources you used to write your lab report.
  • In contrast to MLA format, sources are listed in the order that they appear in your lab report, NOT in alphabetical order.
  • On your reference page, make sure to type/write out the honor code and sign with your University ID. When listing your references, begin on a new page.
  • For a more detailed explanation of how to construct your reference section, check out our Writer's Web guide to referencing sources in APA.
Other stylistic pointers:

Writing with focus

As Shaparenko discusses in her article, "Focus on Focus," successful writing, which includes lab reports, is both focused and clear. In contrast to the flowery and sometimes superfluous language used in literary writing, scientific writing should be direct and concise. To keep this focus in mind, reread each paragraph in your report, identify the main idea, and then verify that the content in that paragraph is needed to support the main idea (i.e. take out unnecessary information). It is crucial that you incorporate background information, such as past studies related to your experiment (note: experiment and study will be used interchangeably on this web page). That said, you must also contribute your own voice, which should be clearly identifiable, by interpreting, analyzing, and/or further developing the information you use.


The tone of your report should be formal, but not too elevated. Remember what your assignment is: to present the findings of a psychological study. Your tone should be scientific and sophisticated, but not to an inappropriate level. Keep these tips in mind as you write your report.


When writing your lab report, use common sense when figuring out which tense to use.
  • Use the past tense to describe studies that have been conducted, as well as your own methods and results.
  • Use the present tense when describing topics which are not bound to a particular time- for instance, when describing a theory, you would use the past tense because the theory itself is not linked to one single study. However, you would use the past tense to describe studies that supported or contradicted said theory.
  • Use the future tense when writing a proposal or discussing future research avenues.


Jargon refers to any technical terms that are specific to a field of study. The general public is not expected to know or understand these terms, so using them in your paper can be confusing. Keep your audience in mind -- if you are writing for a journal, it is more appropriate to use technical terms freely. However, always define your terms, such that an intelligent layperson could read your paper and understand it.

Another problem with using jargon is that it can change the whole tone of the report. You should only use terms that you are very comfortable with -- using words that you do not have a full understanding of, or including terms that you believe make your paper seem "smarter," can be a big mistake. Make sure that you are writing within a comfortable vocabulary. Doing so will ultimately make your paper stronger, because you will avoid misusing terms. A good rule of thumb is this: if you cannot explain the term aloud to a friend, you may want to reconsider using it in your paper.


Try to be as concise as possible in your writing. A psychology report is not the place to practice the type of flowery writing you might use in an English class -- you want to stay on topic and be brief. Here are some tips for staying concise:

  • use effective words -- you do not necessarily need to use the fewest words, but you should choose the strongest words to convey your point.
  • get rid of unnecessary modifiers -- avoid using words like "really," "basically," and "kind of."
  • ask yourself questions -- as you write, ask yourself "am I saying something important in this sentence?" If the answer is no, consider eliminating that sentence.
  • change phrases into adjectives -- phrases can often be consolidated into single adjectives, which make sentences much more concise. For example, "children who have bipolar disorder" could be changed to "bipolar children."

Passive Voice

Scientific writing often encourages the use of the passive voice. In APA style, however, active voice is encouraged, as it specifes the actors in each stage of the experimental process. Consider the following sentence:

  • Participants were led into the testing room and were administered the PNAS through a paper questionnaire. They were asked to complete the questionnaire at their own pace.
The passive construction focuses on the participants (the objects of the sentence, as they "were led") but detracts focus from those who were doing the test administration. This is important information, because an experimenter bias could occur if the researcher who administered the test was aware of what experimental condition the participant was assigned to. Consider this next sentence:
  • A condition-blind lab assistant led each participant into the testing room. The assistant then gave them a paper copy of the PNAS, and asked them to fill it out at their own pace.

This sentence specifies who administered the test, and is a more direct way of stating that information. Always use active voice, if possible.
