  3. MEMORY PERSPECTIVES LEARNING OUTCOMES BY THE END OF THE SESSION, YOU SHOULD BE ABLE TO: Use SPSS to test the first research question in the memory perspectives practical and interpret the output. Use SPSS to test the second research question in the memory perspectives practical and interpret the output. Make a start on writing up your RESULTSandDISCUSSION sections for your lab report.

  4. MEMORY PERSPECTIVES RESULTS The first 2 columns show subject id and group membership. The last two columns show recall for LIST A (BURGLAR) and LIST B (BUYER). (Perspect 0 = BURGLAR; Perspect 1 = BUYER)

  5. MEMORY PERSPECTIVES RESULTS Q1: Do ‘BURGLARS’ and ‘BUYERS’ have different levels of recall for LIST A (burglar relevant items)? RATIO + BETWEEN Ss + 2 GROUPS Independent t-test In SPSS, Independent t-test may be found under analysis >compare means > independent-samples t test.

  6. MEMORY PERSPECTIVES RESULTS Q1: Do ‘BURGLARS’ and ‘BUYERS’ have different levels of recall for LIST A (burglar relevant items)? RATIO + BETWEEN Ss + 2 GROUPS Independent t-test SPSS would like to know what the test variable (DV) is. At the moment, we’re just interested in LIST A recall. We also need to define our ‘grouping variable’ (IV) which is BURGLAR(0) orBUYER(1). We have to tell SPSS that our first group is assigned to the number value 0 and the second group to the number value 1.

  7. MEMORY PERSPECTIVES RESULTS Q1: Do ‘BURGLARS’ and ‘BUYERS’ have different levels of recall for LIST A (burglar relevant items)? RATIO + BETWEEN Ss + 2 GROUPS Independent t-test Levene’s test assesses whether our two groups have homogeneity of variance. If Levene’s is NON-SIGNIFICANT we assume equality. Now for the t-test: t(151) = 6.64, p < .001.

  8. MEMORY PERSPECTIVES RESULTS Q2: Do ‘BURGLARS’ and ‘BUYERS’ have different levels of recall for LIST B (home-buyer relevant items)? RATIO + BETWEEN Ss + 2 GROUPS Independent t-test Let’s repeat this exercise for the second research question. In SPSS, Independent t-test may be found under analysis >compare means > independent-samples t test.

  9. MEMORY PERSPECTIVES RESULTS Q2: Do ‘BURGLARS’ and ‘BUYERS’ have different levels of recall for LIST B (home-buyer relevant items)? RATIO + BETWEEN Ss + 2 GROUPS Independent t-test Now, we’re interested in LIST B (buy_fea) recall rather than LIST A (burg_fea) recall, so switch these test variables around. Everything else can stay as it is.

  10. MEMORY PERSPECTIVES RESULTS Q2: Do ‘BURGLARS’ and ‘BUYERS’ have different levels of recall for LIST B (home-buyer relevant items)? RATIO + BETWEEN Ss + 2 GROUPS Independent t-test Once again, Levene’s test comes through for us, supporting equal variance between the burglars and the buyers. And the t-test: t(151) = -3.90, p < .001

  11. MEMORY PERSPECTIVES RESULTS Q1: Do ‘BURGLARS’ and ‘BUYERS’ have different levels of recall for LIST A (burglar relevant items)? LIST ABURGLARS > BUYERS Q2: Do ‘BURGLARS’ and ‘BUYERS’ have different levels of recall for LIST B (home-buyer relevant items)? LIST BBURGLARS < BUYERS What implications do these two hypotheses have for the memory perspectives account?

  12. MEMORY PERSPECTIVES LEARNING OUTCOMES BY THE END OF THE SESSION, YOU SHOULD BE ABLE TO: Use SPSS to test the first research question in the memory perspectives practical and interpret the output. Use SPSS to test the second research question in the memory perspectives practical and interpret the output. Make a start on writing up your RESULTSandDISCUSSION sections for your lab report.

  13. MEMORY PERSPECTIVES THERE IS NO PRACTICAL SESSION IN WEEK 10 CLARIFY ANY OUTSTANDING ISSUES YOU HAVE WITH YOUR TUTORS NOW...

  14. MEMORY PERSPECTIVES DISCUSSION GET TOGETHER IN GROUPS OF THREE OR FOUR AND REFLECT ON TODAY’S EXPERIENCE USING THE FOLLOWING QUESTIONS What are the flaws in this study? Could I have made one-tailed hypotheses? How would this have changed the p value? What do the inferential statistics NOT tell me about my results?
