Memory Judgment Analyses

Today’s hypotheses

Last time we completed lab 35.Memory Judgment. We still have only one hypothesis, but it actually takes a few analyses to test it:

    Based on the notion that people are not accurate at judging what will affect memory we hypothesize that,

  • Hypothesis 1a: participants will overestimate the effect that word size will have on recognition accuracy.
  • Hypothesis 1b: participants will underestimate the effect of number of times a word is presented will have on recognition accuracy.

To test these hypotheses, it is important to think about what “overestimate” and “underestimate” mean in the context of this experiment and from a statistical perspective.

Please, download the Memory_Judgment_data.sav file from blackboard and open it with SPSS.

Your Turn: Method


  • Participants: What are the demographics of the participants?


  • Variables: How were the variables measured? What are the IVs and DVs?


  • Procedure: How did the experiment work?




  • Hypothesis 1a: participants will overestimate the effect that word size will have on recognition accuracy .
  • Hypothesis 1b: participants will underestimate the effect of number of times a word is presented will have on recognition accuracy.

Your Turn: Results

Analysis time!

  • What are the descriptive statistics of our variables (Mean, SD)?


  • What analyses should we run to test our hypothesis?


  • What are the results?




  • Hypothesis 1a: participants will overestimate the effect that word size will have on recognition accuracy .
  • Hypothesis 1b: participants will underestimate the effect of number of times a word is presented will have on recognition accuracy.

Your Turn: Discussion


  • Briefly summarize the results.


  • Was the hypothesis supported?


  • Are there any limitations that should be mentioned?




  • Hypothesis 1a: participants will overestimate the effect that word size will have on recognition accuracy .
  • Hypothesis 1b: participants will underestimate the effect of number of times a word is presented will have on recognition accuracy.

Any Questions? 🤔

…And Class is over!🙃
