Document Summary

Erp study: 3 groups of athletes, 1. Measuring motor behaviour: level of analyses: performance outcome, describing the movement, measuring the activity of the central nervous system (cns) Performance outcome: measures of time and speed, reaction time: rt: interval between onset of stimulus and initiation of response, rt tasks: Simple reaction time (srt) 1 stimulus, 1 response (most common information processing) Choice reaction time (crt) multiple stimulus, each linked to specific response: example: red, green, light linked to an effector movement, higher level of cognition than srt. Discriminant reaction time (drt) go/no go paradigm: react to stimulus withhold response to stimulus, use to determine inhibitory control deficits. Superior colliculus: retinoptic map of visual and auditory world, various types of cells in sc: sensory cells (visual, auditory) and motory (produce eye movements) If someone has an impairment to sc, cannot maintain eye in constant position would not be able to read.
