Demo SRT

Simple Reaction Time (SRT)

This task measured the basic cognitive process of perception and response execution. The participants are instructed to click on a red circle as soon as it appears at the screen's centre. They were presented with 50 stimuli, and the ISI was jittered using a uniform random distribution between 0.5 and 2 s.

The dependent measure is the speed of response, i.e. the median of reaction times.
