Dot probe task problem with responsekey

Author	Message

Group: Awaiting Activation Posts: 4, Visits: 16	I have downloaded the alcohol dot probe task script. everything works fine except of a problem with the response keys. while it says on the script that this < means left key and that > means right key, on the practice trial it appears to be the other way around. When the probe is on the left side of the screen I press <, I get an ERROR reaction, same thing goes for when the probe is on the right side of the screen, pressing > results in an ERROR sign. What can I do to fix it? Thanks, Anna

Thus #1: Figure out the keyboard scancodes for those keys on your particular keyboard. You do so via Tools -> Keyboard Scancodes... #2: Edit <values> ... /responsekey_left = 51 /responsekey_right = 52 /responsekey_left_label = "<" /responsekey_right_label = ">" ... </values> accordingly.

From its menu, select 'Tools -> Keyboard Scancodes...'. - Press the '<'-key on your keyboard and write down its scancode. - Press the '>'-key on your keyboard. and write down the scancode. - Adjust the portion of the script detailed in my previous reply accordingly.

Group: Administrators Posts: 13K, Visits: 108K	Then everything should be perfectly fine -- those are the scancodes the script expects and works flawlessly with on my test systems. Can you provide (a) a more detailed problem description, (b) an example data file (please attach it to this thread) and (c) specify any changes you made to the script (if any)?
