Unit 2 - Information processing Flashcards
senses ?
they receive information from the environment
perceptual mechanism ?
interprets the information
decision mechanism ?
processes and stores information
effector mechanism ?
executes and controls the movement
movement ?
the performance of the chosen skill
feedback ?
information the athlete receives about their performance
define reaction time
the length of time between the presentation of a cue and the commencement of the movement
display ?
the environment in which the stimuli are presented
signal detection depends on ?
the ability of the sense organs,
the intensity of the signal and
the speed of the stimuli
arousal? what happens if under or over ?
under - sluggish, slow to react
over - performance will be affected by anxiousness, excitement or being over stimulated
what does the performer do during reaction time ?
- detect the signal
- interpret the information
- decide on course of action
- send info to muscles via CBad
- commence the movement
simple reaction time ?
only one possible choice
choice reaction time ?
more choices means greater processing time
stimulus - response compatibility?
if a stimulus and it’s correct response are a good match then reaction time will be fast
