Stroop task and record stimuli presented

CélineG

Good morning,

I created a Stroop task with 5 differents blocks.

Stimuli in each block are presented in a random way.

When I read the file with raw data, I cannot see wich stimuli was presented in each block.

Do you know a way to record all the stimuli presented in the raw data file ?

Thank you very much for you answer !

Sincerly,

Céline

Hi Céline,

If you cannot track which stimulus was shown based on condition parameters, you'll have to log it manually. If you use images, then each stimulus might have a name such as 'image1.jpg'. You then need to log the variable that contains this name. For example if you use the variable stimulus that has 'image1.jpg' as value in a specific trial, you can log this stimulus by means of:

   exp.set('stimulus', stimulus)

in the run-phase of an inline-script. The inline-script needs to be placed somewhere in your trial sequence, after stimulus selection.

Hope this helps.

Cheers,

Joshua
