Hi there, hoping for some guidance,


A trial in my task looks like this:



<trial square_distractpos>


/stimulustimes = [1=focus; 800=distractpos; 1000=targetsquare; 1150=distractpos; 1550=white_out]


/correctresponse = ("j")


/validresponse = ("f","j")


/timeout = 2750


</trial>


The participant is to respond after presentation of the targetsquare and I'm interested in the latency between the presentation of the targetsquare and their response.  When I get my data back, all the latencies are 1200 except for the ones that had an incorrect response.  At the moment I haven't specified data at all - just getting the default.  Is there something you can suggest I specify in the data to get the latency info I need?


Many thanks, hope this makes sense.


Naomi
