Duration time presentation stimuli
I have prepare a Stroop modified task. I wish to reccord reaction time of participants. When the stimulus appears on the screen, participant have to choose between 4 keys on the keypad. Open Sesame reccords correct responses and reaction time.
My problem is that in the keyboard-response, the duration is "keypress". That means the stimulus disappear after the participant gives is answer. So, the presentation time of each stimuli change according the reaction time.
What I want is to have the same presentation time for each stimuli (1000ms).
Here is my code :
set duration 0 set description "Displays stimuli" draw textline center=1 color="[Color_word]" font_bold=yes font_family=mono font_italic=no font_size=32 html=yes show_if=always text="[Word]" x=0 y=0 z_index=0
set timeout 3000 set flush "yes" set duration "keypress" set description "Collects keyboard responses" set correct_response "[Correct_response]" set allowed_responses "q;s;l;m"
I tried to set duration in keyboard response as "1000" ms but it crashes (the task doesn't run).
Can somebody help me with this error ?
Thank you very much !
