How to let a sound continue after a response?

Ang — Thu, 14 Apr 2022 00:20:10 GMT

Hi everyone,

I am trying to program a motor sequence task where the participant responds to visual+audio cues by pressing the corresponding button on the keyboard.
I want participants to be able to respond as soon as the stimulus is starts, but I want each stimuli to be presented for the complete duration (~100 ms).
Currently, if the participant responds before the sound has completed, the sound gets clipped.
I've tried the 'playthrough' = false attribute - but that's not what I'm after.
I've also adding a 'posttrialpause', but my sound still gets cut off after the response.

Does anyone have any ideas? I have attached code for my sounds and the trial where I am trying to presenting the sounds.

Cheers,

An

/ items = ("C4_100ms.wav", "D4_100ms.wav", "E4_100ms.wav", "F4_100ms.wav")
/ select = values.sound_position
/ playthrough = true
/ volume = -2000
</sound>

<trial experimental_trial_3>
/ ontrialbegin = [
    if (values.condition_label == "Bimodal_2" && values.trial_count == 1) {values.trial_type = "Random"; values.item_position = list.random_sequence.nextvalue; values.sound_position = values.item_position}

You'll want the sound set to playthrough = false and the trial's /responseinterrupt set to trial.

Worked like a charm! Thank you so much, Dave!
