I am developing a VSSEP task and am having trouble just conceptualizing how I would control multiple flickering stimuli (8 & 12 Hz) in Eprime. Anyone done this...or have some good advice to share?
Much appreciated!
Paul

| If you are doing displays that fast, I would recommend using the Canvas object and/or Sample: Sprite Manager (Image/Resource Caching) if you have a lot of images. If you are doing something like a flip between < 10 images and cycling them then you can just create x number of canvas and use Display.WaitForVerticalBlank and Sleep to sync them to the rate you wish. If you require responses during this time, then you can have a Wait/TextDisplay at startup that has a longer time limit property.

Hi Brandon,
I appreciate it's been a while since your response but the link to the Sample: Sprite Manager (Image/Resource Caching) unfortunately is no longer active...

Paul, how did you end up approaching programming your visual steady state evoked experiment?
Is there an approach you can recommend?
Thank you kindly

Hmm, the link worked just fine for me right now. Note that you must login to Web Support for the link to work (Web Support login is not the same as Forum login).
