Hi Chris,

Please guide me through my question.

I am trying to setup an experiment with moving grating. There is a property called “speed” in inspector of “Drifting Grating Stimulus”. I am wondering if this property sets the “temporal frequency” of sinusoidal grating in Hz or it is just the speed of moving the stimulus in “deg/sec”. From what I see on the screen it is the speed in “deg/sec” but I want to check it with you.

Regards,  
Sina

Hi Sina,

Your assessment is correct. The “speed” parameter sets the speed, in degrees per second, at which the grating drifts across the display.

If you have any other questions, please let me know.

Chris
