Hello,

I'm gradually familiarizing myself with Inquisit 5 (with excellent help from forum members here :-) ) and am wondering about the accuracy of image stimuli presented subliminally (or that is the goal) at 10ms...or less. Experimenting with different times has brought me to 10ms as a cutoff point between conscious awareness and no conscious awareness. I'm wondering if that is a legitimate cutoff window (from a neurocognitive perspective, I mean) or if the software/hardware combination limits are more of a factor. I'm using Inquisit 5 on a MacBook Pro (2.9 Ghz). I feel like, although I have set it to appear for 10ms, the image is appearing for longer than desired as most research suggests subliminal thresholds are longer than 10ms.

Regards

Jason
