Dear Andrew,
I'm setting a psychophysiological experiment. I'm showing two gabors (one on
the left and the other on the right of the screen) that change their
configuration in a contrast reversal mode following a temporal frequency of
6 and 8 Hertz, respectively.
For every change (for every reversal) in the configuration of two gabors I
need a pulse (trigger) to be sent to the computer that records the EEG
signal. I really don't know how to do that. Can you help me by giving me
some suggestion or example code to do that? I installed winio and when I run
"check config" it says: winio appears to work.
I also display a small arrow; it should appear randomly on the left or on
the right of the central fixation point. Could you tell me how to use the
random module in order to do that?
Thank you so much!!!
Alessandra
