Please describe the difference between experimental design, pre-experimental design, and quasi experimental design.

Explain why you might use one design type over another (you don’t have to describe this for all three but consider what might be a benefit of one design type in a certain situation). Also consider the possible threats to internal validity that can occur with each design type that may impact your choice. (In other words, it might be best to come up with an example and describe which research design you would use and why.)


What reactions do you have to The Man Who Mistook His Wife for a Hat? Can something be taken away from this case study and be used for understanding other situations? Do you think this case study could have been developed as a single-subject design instead (or that a similar case could be treated as a single-subject design in the future)?

SQ7 – 2 options

For SQ7, please respond to one of the following two options:

  1. Discuss your hypotheses for Paper #3. Keep in mind the general research question: Is there a difference in response time when taking two versions of the Stroop test with and without a noise distractor?
    For your hypotheses, what do you expect to find once we run our results? You may have similar hypotheses to others in the class but you should still make sure that these make sense to you and are related to the readings (thus far). You will be able to expand on these for your paper once you read your other articles, but you need to have a strong foundation of your hypotheses before we run our results.
  2. Describe executive functioning generally and inhibition specifically. Inhibition is the focus of our paper, but it is part of the larger concept of executive functioning. Using the Miyake et al. (2000) article and Stroop’s (1935) discussion of inhibition in the introduction of his paper, describe executive functioning and inhibition, as it applies to our study.


For this study question, state at least one of your hypotheses and the subsequent correlation results you found. Make sure that you have justification and rationale for why you are hypothesizing what you are hypothesizing (this is necessary for your paper, you don’t have to write out the full rationale here). After you present the results (report statistics in APA format), discuss what you found and why it may or may not support your hypothesis. Some of you will have the same hypotheses and findings – you can use this space to brainstorm why the results did or did not support your hypotheses.

For Paper 2 Data Collection

Recruit at least 3 participants! Each participant should:

  1. Complete the Big Five Personality test: http://www.truity.com/test/big-five-personality-test
  2. Complete the Student Learning and Studying Behaviors survey
    1. Score their survey after they are done – follow the scoring guide!
  3. Input participant data on googledoc
    1. Use your initials and then enter the data from each of their questionnaires

MAKE SURE YOU ALTERNATE WHICH SURVEY YOU HAVE THEM COMPLETE FIRST! (So if your first participant does the Big Five first, have your 2nd participant take the studying survey first.)

Please complete your data collection by Sunday at 8pm.


Like all experimental designs, within-subject designs have limitations. But instead of focusing on disadvantages, please describe the advantages that a within-subjects design can bring. What might be a scenario in which choosing a within-subjects design would be more appropriate than a between-subjects (between-groups) design?


For SQ4, please review the 2nd draft of the student learning and studying behaviors survey. Consider any wording that may still need to be modified and answer options that need to be further developed. I have left some notes in caps on questions that the class was split on.

In addition, we need to define ‘studying’ and ‘assignments’ for our participants. If you have an idea of how these can be defined, please also post that here.

You don’t need to address every single question in your SQ response. Focus on what sticks out to you and what may need more work. I think it might be best to post your responses directly on the blog, rather than in individual word docs, but I leave it up to you to decide how you want to respond to the SQ.
