Levels of Processing Analyses

Today’s hypotheses

Last time we completed lab 29.Levels of processing. The hypotheses related to this lab that we will test today are:

Hypothesis 1: The type of processing level (visual, phonological, semantic) will have a significant effect on recall accuracy in phase 2.
Hypothesis 2: Recall accuracy for visually encoded words will be significantly worse than recall accuracy in phase 2 for phonologically encoded words and semantically encoded words.
Hypothesis 3: Recall accuracy for phonologically encoded words will be significantly worse than recall accuracy in phase 2 for semantically encoded words.

Please, download the Levels_of_Processing_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 1: The type of processing level (visual, phonological, semantic) will have a significant effect on recall accuracy in phase 2.
• Hypothesis 2: Recall accuracy for visually encoded words will be significantly worse than recall accuracy in phase 2 for phonologically encoded words and semantically encoded words.
• Hypothesis 3: Recall accuracy for phonologically encoded words will be significantly worse than recall accuracy in phase 2 for semantically encoded words.

Your Turn: Results

Analysis time!

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




What analyses should we run to test our hypotheses?




What are the results?

• Hypothesis 1: The type of processing level (visual, phonological, semantic) will have a significant effect on recall accuracy in phase 2.
• Hypothesis 2: Recall accuracy for visually encoded words will be significantly worse than recall accuracy in phase 2 for phonologically encoded words and semantically encoded words.
• Hypothesis 3: Recall accuracy for phonologically encoded words will be significantly worse than recall accuracy in phase 2 for semantically encoded words.

Your Turn: Discussion

Briefly summarize the results.




Were the hypotheses supported?




Are there any limitations that should be mentioned?

• Hypothesis 1: The type of processing level (visual, phonological, semantic) will have a significant effect on recall accuracy in phase 2.
• Hypothesis 2: Recall accuracy for visually encoded words will be significantly worse than recall accuracy in phase 2 for phonologically encoded words and semantically encoded words.
• Hypothesis 3: Recall accuracy for phonologically encoded words will be significantly worse than recall accuracy in phase 2 for semantically encoded words.
