Homework for the next two weeks

Homework 1 (individual): Practice p-hacking

🔗 P-Hacker App

Task: Hack at least 5 studies towards significance with \(\alpha = .05\) (keep the true effect at 0). Whenever you achieved a significant result, click on “Save” in the results table to store your result in the study stack on the right side. Once you achieved 5 significant studies, copy and paste the study stack into a text document.

Next, try the same for \(\alpha = .005\) (if it takes too long, there’s no need to achieve 5 significant studies).

Deliverable: Copy both sets of significant studies (one for \(\alpha = .05\), one for \(\alpha = .005\)) into the textfield in the Moodle task.

Homework 2 (individual): Read our target paper

Read the target paper: Stellar, J. E., Gordon, A., Anderson, C. L., Piff, P. K., McNeil, G. D., & Keltner, D. (2018). Awe and humility. Journal of Personality and Social Psychology, 114(2), 258–269. https://doi.org/10.1037/pspi0000109

You can find the PDF in Moodle.

Focus on the introduction, our target Study 3, and the discussion. Skim the other studies. Then write short replies to these guiding questions:

  1. In the literature are several definitions of “Humility”, and they assign it to different classes of psychological constructs (e.g., a trait, a state). List at least 4 different classes.
  1. How do the authors treat humility comceptually?
  1. What is the definition of “awe”?
  1. Compute the effect size (i.e., the standardized mean difference) between the control and the experimental group concerning strength of elicited awe.
  1. Which limitations / contraints on generality (see definition CoG) do the authors discuss in the General Discussion?
  1. Bonus question: There is an objective error concerning the sample size in Study 3. Can you spot it?

Deliverable:

  • Please write the answers directly into the answer field in Moodle. (You can of course write the answers beforehand in Word or something, and then copy the answers in here).
  • You can answer in English or in German.
  • Most questions can be easily answered in one sentence. Feel free to copy and paste the relevant sentences from the paper.
  • If you are tempted to use ChatGPT, better don’t do the homework at all (after all, the goal of this exercise is that you learn something, not that you make your lecturer happy).

Homework 3 (individual): Fill out the CREP survey (3 min)

See link in Moodle.

Homework 4 (individual): Complete the Git tutorial.

Complete and/or re-do the Git Tutorial. You should be able to initialize a local repository and commit to it, connect it to a remote repository on Github, and push, pull to it. All of these actions are covered in the tutorial.

Deliverables: Create a Github repository (you can call it whatever you like), push at least least two local commits to it and copy the link to the repo to the Moodle task.
