I’m looking at the Superlab experiment that demonstrates how to create macros. (In the experiment participants respond to 2 stimulus lists: one contains words, the other contains nonwords). If the participant presses ‘y’, indicating then it is a word, then this is coded as Yes; if they press’n’ for no, then this is ocded as no.
Clearly in this experiment y and n are the only important keys. How do you prevent Superlab from reading other keypresses, which it appears to do ?
