Re: Frequency analysis
That is a definite issue – I’m not sure of the correct chance proportions would be. For those not familiar with the task, participants read a list of words such as “moth insect wing bird fly bug cocoon color net” and ask recall or recognition. The false memory occurs when a participant falsely remembers the critical word – in this case, “butterfly”. I don’t think it’s correct to say that 50% is the correct chance proportion but I’m not sure what a correct value would be. It is likely that a 55% false memory rate is higher than false alarm rate on a word list task where the list consists of unrelated words, but again, I’m not sure where to go with it. The bottom line is that I would like to be able to claim that the 55% rate reflects a strong tendency for false memory to occur.

It sounds like you're looking for the binomial test. It's not clear what
proportions you expect in the two categories by chance, but if it was 50%,
the command would look like this (where "recalled" is an indicator variable
for recall, 0=No, 1=Yes):
NPAR TESTS
/BINOMIAL (0.50)=recalled
/MISSING ANALYSIS.
