Hi, Michael. Thanks for responding.
Well, let me see if I can clarify my issue with and example.
Think of a semantic decision task that presents several sequences of stimulus pairings in the following way: fixation point -> prime stimulus -> inter-stimulus interval -> target stimulus -> question mark. Consider that primes are ‘cat’, ‘snail’, lion’ and targets are ‘pet’, ‘pest’, ‘beast’. I’m trying to figure out how to generate an output which shows in which moment of the task the stimuli were been preseted. For example, at 00:01:00, the prime was ‘snail’; at 00:01:015, the target was ‘pest’; at 00:01:20, the participant pressed key ‘y’, et cetera.
