I created a separate document for getting started in this class, it covers some technical aspects as well as some perspective. So you should check that out first. See document at Getting Started
In many ways the teaching of science makes it sound easy. In the physical sciences like chemistry and physics and biology there is often a lot of emphasis placed on the technology necessary to do those disciplines. As there should be.
But with that, it can happen that people begin to equate the scientific method with the use of technology.
This is simply wrong. I’m not saying those who practice physical sciences or even teach science in those disciplines are suggesting that the technology is what makes science possible.
Technology makes doing science somewhat easier. And it may help us discover things that would impossible without it (imagine immunology without a microscope).
Unfortunately in the social sciences we really don’t have technology in the same way that medicine has an MRI scan or how physics can you use particle collider.
We have to do something different. We have to think more deeply about constructs. Ideas. Relationships. We have to think very clearly about the relationships between ideas. All science does this, but the social sciences have a larger burden because so much of what happens in that discipline is less tangible than the material found in physical sciences.
And Psychology has serious problems as a science. Not because it’s unscientific but because a lot of the practitioners of the science in Psychology are not thinking well, and therefore aren’t doing science well.
And as I teach this class I worry about my own incompetence because I appreciate how hard things are. None-the-less, here we are.
So when I think about how to teach research methods in the context of psychology, I have to ask myself of the following, upon which do we focus?
| Focus issue | Area of expertise |
|---|---|
| Why does a particular event happen the way it does? Is there a model that explains this? | –Theory expertise |
| What work in this discipline has already been completed? | –Library expertise |
| Given a question or hypothesis, how do we perform an experiment so that the results of the experiment demonstrate temporal precedence, correlation, andrules out other explanations? | —Methods expertise |
| To perform those methods, what logistical and program management needs exist? | —Project management expertise |
| Given the nature of the data, the methods of collecting the data, what statistical decisions need to be made to interpret this research? | —Statistical expertise |
| How do we document and share our process of discovery? Who writes the report for publication? | —Writing expertise |
| Given this project, how is one to pay for it? Who writes the grant application? | —Funding expertise |

By the end of this week 1, I would like for you to have gotten a bit familiar with slack, and Google Documents, and maybe even flirted with downloading and installing Zotero. Regarding Zotero, I intend to make a quick video or document showing the steps of getting it up and running So you can afford to put that off.
Conceptually, though, there’s some very big ideas that I hope you have a chance to learn. Broadly speaking, these ideas include what we mean by epistemology and it’s sub-fields, the relationship between critical thinking and science, your own personal definition of what science is, and probably the most important abstract idea will be John Stuart Mill’s 3 criteria for proving causality.
Here are some key questions:
How do you know, what you know?
What is empiricism?
You may have to look the following up:
What is the difference between a hypothesis and a theory?
If a logical statement is contradicted by empirical discovery, which one would you prefer to believe? Can you justify that?
How should researchers evaluate the quality of the research?
What are the practical steps of the scientific method? Do they at all relate to Critical thinking? How?
What biases should researchers be concerned about?
Open a google doc and write down some responses to the following prompts. Write a paragraph or 2, and don’t try to incorporate any of the other reading below. Give your your page a title (not the document, the page–you can title your document as you wish). Here are the prompts:
what is your process for thinking clearly?
How do you know something is true?
George Orwell, Politics and the English Language, 1946 (in the syllabus)
Read Schwartz (2008), The importance of stupidity in scientific research
Look up the definition for the following concepts using 3 non-self-referential sources (in other words, don’t use a source that references one of your other sources):
Introduce yourself in Slack channel #introductions
On the same google doc, make a new page [Cmd or control + ‘enter’] and write down some of your interests in psychology. Remember that this will be a public document. If you have some ideas you want to write down privately, make a separate doc. These ideas may develop into research questions
In the same google doc, and again, with a new page and title, write a reflective/summary/reaction to the reading material above. Don’t summarize, synthesize. Your mind may be swirling about many ideas of epistemology and science, but try to write down some ideas that you have–things you’ve learned, emotional reactions to things that have been said. In fact, pay close attention to your feelings as you read things; if something controversial comes up, you’ll feel it pretty quickly. These feelings can be guides for your own curiosities and fears/biases. In google docs, highlight your title, go to ‘insert’ –> ‘bookmark.’ You’ll see a little blue icon and the word ‘link’ next to it. Copy that link and post it in #4…
Post this link to the Slack Channel ‘week-1-reflection’
Read some posts by your class mates. Commenting is optional.
For week 2 we’re getting into more practical ideas about controlling an experiment to manage confounds. Confounds, or confound variables, are variables that muddle interpretation of experimental outcomes.
If you do a psychological experiment on whether different personalities manage stress differently, you need to account for people’s mood. If you ignore mood, it can systematically interfere with your dependent variable. And so any outcomes in your research will be uninterpretable you can say it’s been confounded.
I have made a blank Google document that anyone with the link can edit. The purpose of this is for you all as students to an honest book anonymously write down ideas, broad topics really, about psychology that you would want to research.
The goal would be for me as your instructor to curate and guide you all into finding a practical and simple experiment that we can do in this class that is tied to the broad topic.
The motivation is for you to be able to study something of interest, but for your instructor to keep it simple enough that the process is both educational and satisfying, and not so complicated that it becomes impossible.
| experiment | treatment condition | matched-groups design | external validity |
| independent variable | control condition | within-subjects experiment | mundane realism |
| dependent variable | randomized clinical trial | order effect | psychological realism |
| conditions | no-treatment control condition | carryover effect | construct validity |
| control | placebo | practice effect | operationalization |
| extraneous variables | placebo effect | fatigue effect | Statistical validity |
| manipulate | placebo control condition | context effect (or contrast effect) | subject pool |
| single factor two-level design | wait-list control condition | counterbalancing | experimenter expectancy effect |
| single factor multi level design | between-subjects experiment | complete counterbalancing | double-blind study |
| confounding variable | random assignment | random counterbalancing | manipulation check |
| treatment | block randomization | internal validity | pilot test |
How to organize these vocabulary? My advice would be to try to mind map them. Like draw some pictures or flow-diagrams, (?Venn diagrams?) where the terms cluster together. This is not a requirement. I’m just saying that I would NOT try to brute force memorize these terms. Instead, start looking for relationships. I might demonstrate this.
Key ideas in this chapter are some classic techniques for dealing with John Stuart Mill’s three criteria of causality, ruling out other explanations. But in particular this chapter on experimentation is about the management of confound variables.
You should also be able to draw a basic DAG
If you want to test your learning on this chapter, try describing an experiment that proves tapping on an agitated soda can (no, not an angry one) will reduce the amount of carbonated fizz the escapes upon opening.
This will probably always be a draft. I showed this a bit to you on Monday. I think it’s mostly done, which means it’s mostly for me to wrap my head around timing of work. The first month is ridiculously fast but needed for the rest of the quarter to work out.
Methods Flow diagram
Textbook, Chapter 5 The Experimental Method Possibly the most important chapter for the quarter
Textbook, Chapter 3 Research Ethics yes, okay, this is very important too
In your main google doc, the one to rule them all, make a page of 6-10 psychological topics that you’d like to perform an experiment. By the end of the week, you will want to highlight 3 likely candidates
With any or all of your ideas from #1, contribute to the brainstorming google doc mentioned above.
Pick one of your ideas, and see if you can hand draw a DAG. https://excalidraw.com/ might serve you well. Be sure to save your work…you can download it as a text file (technically json file type) or just save it as an image. You don’t have to share these, but you could put them in your google doc
Make another page in your google doc, title it Ethics summary (or something), and in your own words, summarize the very big and broad ideas you picked up from chapter 3. Keep this somewhat brief. Go for pith.
Do the same for Chapter 5 (new page, new title, etc.)
5a. Make a post with chapters 3,5 ideas and post to #week-2
What follows below is predominately individual work that is going to be used to cross over into more group work.
This week is somewhat of a transitional week which complicates my instructions.
On the one hand you need to keep practicing our individual understandings of research methods, dags, causal storytelling.
On the other hand we need to get into groups. But getting into groups it’s somewhat of its own process and is going to take place over the next few days. I hope is that by Tuesday, Wednesday at the latest we have our groups, so that we have a a week to put together a very rough draft of experiment that we could apply to the human subjects research committee.
So, even though we may not be in groups at the beginning of the week, we can at least start looking at North Seattle requirements for a application and we can continue to practice thinking about our causal diagrams– The dags
Early in the week pick a group/topic (tough given time pace)
See the application materials for applying to North Seattle College’s Human Subject Review Committee (HSRC)
Begin drafting, debating, drafting, drawing more DAG’s, drafting some rough ideas for experiments
After reading/watching the above…
Review the anatomy of a journal article, found in Getting started, appendix, anatomy…
Write a brief outline or flow diagram, whatever, for running an experiment on one of your personal research ideas. Keep it simple. This is an individual assignment, so put it into your ‘one doc to rule them all.’
Instructor Note to future self …this particular step, #2, assumes that student would do an individual dag that’s related to a group that they have yet to be assigned. So, maybe group forming week 1.
* Put your attention on to a basic hypothesis and the Method (as described in #1).
* Essentially, this is a very rough draft of a proposal.
* a pandemic testable hypothesis is what we are going after
* draw a rough draft DAG of the related variables.
* if you drew this on paper at home, take a picture of it and paste it into your google doc
For example, If I were to continue my example from the virtual meeting:
People induced into a mild sad mood will indicate higher levels of introversion as measured by the Big Five personality test.
People recruited from North Seattle College’s social science classes Winter 2021, maybe some subReddit
Simple, short version of The Big Five personality test Beck depression inventory Song ‘Hurt’ covered by Johnny Cash,originally by Nine Inch Nails. Reznor (1994)
After providing informed consent, participants will be given a link to a Google form that we’ll begin with instructions. The first section of this Google form Will be differ based on the experimental condition. Some participants will be given a link to a YouTube video of Johnny Cash’s version of the song Hurt originally by Nine Inch Nails. other participants will be given a link to a picture of a tree.
The instructions will say to listen to or watch the stimulus for 3 minutes. while viewing participants will be instructed to make some notes about their thoughts and feelings.
After the 3 minutes, the participants will be invited to go fill out the Beck Depression Inventory and a survey which will include questions from the Big Five personality test in particular the level of introversion.
Optional at this point…but get into the habit of thinking about these.
Pick/be-assigned-to a group. More on this later.
In your chosen #group-channel, post your Dag but without a narrative describing it.
Look at 3 of your classmates’ Dags (in your topic channel) and try to add a narrative to the Dag in a comment.
In your chosen group #channel, see if you can find agreement on a simple hypothesis
There’s a lot to do and of course never enough time to do it.
Hash out a reasonably clear hypothesis that could serve as a springboard for our work. It doesn’t have to be perfect. But we do need something for our application to the human subject research committee (HSRC) in 1 to 2 weeks.
Think about what, if any, harm the experiment may cause. What is the impact? What would be the impact on someone who has, schizophrenia, for an extreme example? If we don’t want to harm someone with schizophrenia, what could we do to protect them?
Think about the actual logistics of an experiment. This will become more foreground as the week progresses.
Honor the difficulty in group work.
Our goals are to:
Produce a draft of a hypothesis, materials, and procedure grounded in some very naive understanding of our group topic. In other words, what are the:
Eventually a procedure (probably more next week)
Become familiar with issues of measurement, paying particular attention to the following:
Nominal, Ordinal, Interval, and Ratio Forms of measurement.
The different kinds of validates and reliabilities.
Have basic exposure to alternative methods to ‘true/lab’ based experiments in chapter 5. Quasi-experiments (chapter 8).
Lastly, and this mostly falls on me but as a class we’ll need to think about some tech in how we can actually get participants to our experiments. Your instructor can get word out for students to participate; possible participants could have a link to a website or something…but we need to think about ‘then what?’ How do we control how a participant would be assigned to one group/condition vs another. Again, this falls on the instructor a lot.
Template for proposal and application
Group Processes
Doing group work is hard. There are a lot of complexities to doing group work. People take classes on how to do groups. It is totally reasonable to have concern about how group conflict can derail a project.
But groups can also save time. Instead of your instructor giving feedback on 24 different projects, they can help several groupings of students more quickly.
Groups can disperse work load, and group members can help each other with various edges of development.
The following document is often presented as a classic way to think about how groups form and eventually work. Skim it, and note that I’m not a fan of the language. But it does capture the patterns of group formation: Some basics of group work
Your instructor will do their best to help manage any difficulty that arises from group work.
Read the following 3 chapters.
A. Textbook, Chapter 4 Psychological Measurement
B. Textbook, Chapter 7 Survey Research
C. Textbook, Chapter 8 Quasi-experimental research
| Person | Chapter |
|---|---|
| a | 4 |
| b | 4 |
| c | 7 |
| d | 7 |
| e | 8 |
| f | 8 |
On the other hand, if a group of 6 divides the work so that each person reads 2 chapters, then each chapter will have 4 different people looking at it: So, 2 people read ch’s 4 and 7, 2 people read ch’s 7 and 8, 2 people read ch’s 4 and 8.
| Person | Chapter |
|---|---|
| a,b | 4,7 |
| c,d | 7,8 |
| e,f | 4,8 |
Returns:
| Chapter | Person |
|---|---|
| 4 | a,b,e,f |
| 7 | a,b,c,d |
| 8 | c,d,e,f |
The 2nd approach may ensure that each chapter has it’s secrets uncovered. It certainly doesn’t have to be this complicated. It is really up to you.
Find 2-3 sources on your group topic (if you haven’t already).
In your one document to rule them all, write down some brainstorm ideas. Maybe some dags, maybe some hypotheses. Your audience for this will be your group-mates. Post links in your group channel to your work. Have this done sooner than later. many of you are already doing this. Yay!
After watching the DAG video above, see if there are new paths in your personal DAG that might lend itself to an experiment or quasi-experiment. many of you are already doing this. Yay!
By end of the week, groups should have some very rough drafts of:
To decide upon specific surveys and materials for the study, with a special urgency on any material that may ethically impact a participant.
Get as close as possible to finishing the HSRC application this week. The goal would be Friday.
To have Clarity between the instructor and your groups process for the research-group-to-student-to-survey-data pipeline.
To do first self-reflection
How to make survey google docs (under construction..maybe a video?)
Review chapter on Surveys
Read/skim Nancy Chick, Metacognition
Read/skim Alfie Kohn, The Case Against Grades
Take a look and then go for a walk or something and let yourself ponder these questions
the text boxes you see in this ‘quiz’ will expand to accommodate what you need to write. In other words, don’t feel like you must only say like 3 words.
When filling out the self-reflection survey, take a look at the research methods syllabus and pay attention to our course and program outcomes to think about what you are learning.
Review and give thoughts about process for obtaining participants
Assign people to tasks. I recommend the following tasks
Draft a proposal (individually) –this is for your development but can be used to synthesize with other students in your group. Here is an outline of a proposal
Post your individual proposals (of group project) to #week-5-proposals
By Friday(ish) as a group have some agreed upon outline of a proposal. The proposal is your groups guiding document. We may make changes to it as the quarter goes, but it’s effectively our blueprint.
Submit HSRC application before February 8th.
Goals: to get back into the swing of thinking about writing and to practice drawing graphs and making some quant predictions.
When you read Craft of research, remember I’m not testing you on this. I’m hoping to expose you to a well written book that discusses a particular kind of thinking. While reading, take notes about things that grab your attention.
Read Chapter 1 of the Craft of research
Look at the table of contents for Chapter 4-6..read whatever grabs you. Or not.
Read chapter 7
Make sure you have a system for references. Revisit, if necessary, video instructions on using zotero. Seek instructor guidance about using that tool
Write a paragraph or so in your one document to rule them all that summarizes your thoughts about the craft of research readings. Share in the #craft-research channel
Using your proposal as a draft, create a new document outside of your One-doc-to-rule, and create a full-fledged outline for the whole paper you’ll be writing. Many parts will be empty or very light in terms of completeness. I’m hoping that this doc captures your work for the final paper that you’ll be writing along side your group.
In your one-doc-to-rule, make quant predictions of your outcome variables organized by group/IV (The descriptive stats chapter will help)
In the same section of your one-doc-to-rule, make or link to a graph (not a dag) that shows what you expect/hope to find and put it in your one-doc-to-rule. Share to #graphs channel. You don’t have to use exaclidraw. Draw using something at home, take a picture, and insert it into your google doc if that is easier.
From what I can see, most of your hypotheses will be expressed by a bar graph.
If you aren’t sure, you can certainly check in with your instructor.
please include your hypothesis, which should be logically represented in the graph.
For example, I just made up some graphs, a bar chart with a scatterplot beneathe it
Rough Draft schedule final weeks
I’m trying something new by adding due dates in three places. Here at the top and then in the ‘read/do stuff’ for each week, and then finally in linear form at the end of our whole document here.
Brian’s videos on the P-value. They come from a longer video on stats which can be seen in Week 8 below
Craft of research
I have a few videos for you to watch, as necessary. The first two are from some twitter statisticians that I follow. My video is about 20 minutes long but I’ve broken out the key ideas, hopefully, at strategic places so if you want to skip around or come back to a section you can. The presentation slides that goes along with Brian’s videos can be found here: presentation slides
There is something missing here. Not sure the best way to provide guidance here.
This will be a very difficult time because it requires that groups be on the same page of knowledge. What is a number (see Textbook Chapter 4, Psychological Measurement), what kind of comparisons are appropriate for the research question (Chapter 13 Inferential stats). Brian anticipates lots of complexity.
Don’t look at the data with an eye for analysis. Temping, I know, but it’s best to just let data happen as time goes on.
