How to reload identical stimuli with noresponse?

https://forums.millisecond.com/Topic28072.aspx

By Amarins - 12/10/2019

Hi all,

I want to use the noresponse option to let participants re-perform a trial with identical stimuli (pictures) to which they did not respond. However, when I use the response option, a trial is reloaded but the stimuli are randomly selected. So I wonder how I can assure that identical stimuli (product_susleft+ product_unsright or product_susright + product_unsleft) are reloaded for noreponse. Can anyone help me?

Thanks a lot!

 

Below you can find my code:

<trialsus_left_ct>

/ stimulustimes = [1 =product_susleft, product_unsright, earth_static]

/ correctresponse =("a")

/ validresponse =("a", "l")

/ pretrialpause = 500

/ timeout = 20000

/ responsetrial =(noresponse, sus_left_ct)

</trial>

 

<trialsus_right_ct>

/ stimulustimes = [1 =product_susright, product_unsleft, earth_static]

/ correctresponse =("l")

/ validresponse = ("a","l")

/ pretrialpause = 500

/ timeout = 20000

/ responsetrial =(noresponse, sus_right_ct)

</trial>

 

<pictureproduct_susleft>

/ items = sustainable
