It's the first time for me to do analyses with e-prime, and I have to analyse some data from an experiment. The data are, at the moment, in e-prime. I'd like to have the accuracy, the hits, and the false alarms for every subject. When I am in the anaylse window:

  1. Accuracy: I drop the subjects into the rows, and the Target ACC into the Data window. But do I take the ACC mean or the ACC count?

  2. Hits: Isn't it the same as accuracy? And, if not, what is the difference?

  3. False Alarms: do I just count them? How can I make it then comparable over different tasks (some tasks have more trials than the others).

You might want to check out this signal detection theory tutorial that talks about vocabulary in SDT including hits versus hit rate, and false alarm versus false alarm rates. – Jeromy Anglim Oct 11 '13 at 5:01
