.corr always 0/incorrect

OS (e.g. Win10): Windows 10
PsychoPy version (e.g. 1.84.x): 1852
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?: Accurately scored output - everything is always wrong

What did you try to make it work?: I have a very simple dot probe. I have “store correct” selected and have tried putting in: left, ‘left’, and [‘left’] but none of them score as correct despite the csv output showing that left was pressed.

The attached has two trials. The correct answer for the first one is ‘right’ and the second is ‘left’. I have tried a bunch of trials and all of them show up as key_resp_3.corr
=0.

Hi @Heather_Cohen, for the keyboard component you could select the option to store only the first response, and add the correct response as left or right with no brackets or quotation marks. Then, the keyboard component should register correct or incorrect responses correctly - see example attached

Thank you! I knew it was something simple I must be missing.
