I’m constructing a lexical decision task with the builder and I’m writing to ask whether it is possible to register the temporal alocation of stimuli and responses across trials. In Matlab there is a function called GetSecs. Is there something like GetSecs in the Psychopy? Best Regards, Marcelo.

Hi, Michael. You’re right. The builder does it all for me. I was thinking that I had to insert extra commands to get all these information. I was thinking that Psychopy works the same as Matlab. Thank you!

[image] Marcelo_Silveira: whether it is possible to register the temporal alocation of stimuli and responses across trials Can you define exactly what you mean by that? You are presumably controlling the time of occurrence of your stimuli, and collecting responses, so both of these things sho…

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 m…

Hi, Torge. I need more than just reaction times. I need outputs showing which stimuli was been presented in a given moment. I’ll give you the example I gave to Michael. Think of a semantic decision task that presents several sequences of stimulus pairings in the following way: fixation point -> pr…

I’m still puzzled here. You already control when the stimuli are presented, they don’t just pop up on screen of their own accord. So you already know when they were presented, and those times (if they were specified in a conditions file) should be automatically saved for you by Builder in your data …

Hi Marcelo,

maybe core.Clock() is the function you’re looking for? It helped me record response times across trials in a similar situation.
