motor behavior quiz anticipation
central resource theories
-1 central pool of attention to be divided
Anticipation perceptual and design training
-Instruction -cue vision/attention, questioning, feedback -Simulations -competitions: tactics, phase play -Activities to promote effective visual search, -modified games (1-touch, silent), video study
why PRP occurs
-RP stage is serial -processing the 2nd stimulus must wait for the processing of the 1st to be cleared out
benefits of anticipation
-avoid full and slower I-P and RT -simplify SID -skip RS -simplify/shorten RP
types of anticipation (receptor)
-detecting upcoming events with various sensory receptors
costs of anticipation
-errors (incorrect timing or accuracy) -slower than normal RT -psychological refractory period
types of anticipation (effector)
-estimation of how long his or her own movement will take
kahnemans model
-flexible capacity depends on individual, task, and situation -arousal dictates available capacity
Behavior training
-focuses on repetition
anticipation strategies
-force opponents to react vs anticipate -randomization, variation, unpredictability -force opponents to incorrectly anticipate (causing longer than normal RT) -reduce own S-R alternatives -repetition of S-R tasks to increase compatibility -visual search and perceptual training/practice
result of skilled visual search
-increased benefit vs cost of anticipation -faster I-P and reaction time -earlier and more accurate predictions and play recognition
attentional capacity
-limited attentional capacity -manage attention through processing, space, allocation, shifting
Visual search
-measuring what performers are looking at -eye movement/tracking -gaze/fixation control -timing, duration, and location of fixations, saccades, pursuit tracking
Visual search skilled vs unskilled
-more efficient visual search patters/behaviors -faster in detecting and recognizing most relevant stimuli -accurate in seeing advanced visual cues and information
internal focus
-movements of body that make the action
Decision training
-perceptual training
types of anticipation (perceptual)
-predictability of environmental events (practice/experience)
spatial anticipation
-predicting what will happen
temporal anticipation
-predicting when something will happen
psychological refractory period
-reaction time to a 2nd stimulus after the 1st has been presented -delayed longer than a normal RT -when 2nd stimuli is presented 40-60 ms inter stimulus interval (ISI) results in delay of 2nd RT
types of anticipation
-receptor -effector -perceptual
factors for spacial anticipation
-regularity of events -# of stimuli
factors for temporal anticipation
-regularity of timing events -speed of stimulus -distance of stimulus
attentional focus theories (primary issue)
-shifting of attention focus -individual styles
attentional focus theories (direction of attention along 2 dimensions)
-width -direction
external focus
-
