Hello,
I’m designing an experiment that consists in the presentation of a face in the right or in the left of a cue, placed in the center of the screen. The subject has to answer Y or N depending on the instruction of the block.
I want the cue to be in the center of the screen the whole experiment, but what I have done now is such as flickering.
Each trial consists in:
-
An event (cue) that is a cross in the center, and without the settings: “erase screen before presenting stimulus” but with “keep stimulus invisible”.
-
A picture (left or right position), 200 ms, without the settings: “erase screen before presenting stimulus” and “keep stimulus invisible”.
-
A response time that is a cross in the center with the settings: “erase screen before presenting stimulus” but not “keep stimulus invisible”. (If the option “erase screen before…” is selected, the face remains there).
-
An ISI time that is again a cross in the center, time variable, and without the settings: “erase screen before presenting stimulus” and “keep stimulus invisible”.
I don’t know if I’m doing it correctly.
Can anybody help me?
