4 - Cognitive Factors of Movement Flashcards
what are the cognitive factors that influence movement? (3)
- anticipation
- attention
- multitasking and movement
what are the 2 categories of anticipation?
- effector anticipation
2. temporal anticipation
def: predicting how long it will take the body to make a response and initiating body movement before the stimuli arrives to put them as close to each other as possible
effector anticipation
def: knowing when a stimuli is going to occur so you are prepared for it happening
temporal anticipation
def: the time between warning cue and the onset of the stimulus
fore period
if the fore period is short, it leads to _____ reaction time
slower
if fore period is too long, it leads to _____ reaction time if there are not catch trials mixed in
faster
def: a trial where the stimuli is with held, makes the reaction time slower when pre cue is present
catch trial
def: the information processing capacity of an individual
attention
def: type of task where a pre cue indicates where to look for a stimuli, gaze and attention shift together
pre-cue paradigm
def: there is a capacity for any individual ability to process information, if 2 tasks performed at the same time go over this capacity, the performance of the tasks diminishes
dual task paradigms
def: reaching the cognitive limit of information processing when multitasking
capacity interference
def: there is decreased performance when multitasking that is caused by physical structures (making 1 hand do multiple things)
structural capacity
cognitive decline is associated with?
- slower gait cycle
- inability to walk and do other things
- scan environment differently
def: tests that examine your cognitive processing ability with simple tasks
executive function tests
def: having to respond to a “go” or “no go” stimuli
go or no go test
def: stimulus is names of colours that are coloured differently to the word itself
stroop intereference
def: having to draw lines between an ordered set as fast as possible
trail making test
what type of relationship does arousal and performance have?
inverted U with maximum at moderate arousal
when is optimal performance? when arousal is at what level?
moderate arousal
complex skills require ______ arousal levels than simple skilss
lower
def: the stage where the stimulus is identified or recognized
stimulus identification stage
def: is the stage where you decide how to respond to a stimuli, is affected by # of response options and stimuli response compatibility
response selection stage
what is decision making on whether or not to respond to stimuli affected by?
- # of choices to respond with
- how compatible the stimuli and response are
def: stage where a motor program is retrieved. prepared for activation, and executed
- occurs after or at the same time as response selection stage
- reaction time increases when the response is more complex
def: the delay period when you can’t select a second movement because the first one is still being processed
psychological refractory period
T or F: processing stimuli 1 causes interference with processing of stimuli 2
true
def: if SOA(stimulus onset asynchrony) is very small, the two stimuli will be considered as 1 more complex stimuli
grouping effect
what can stimuli processing be affected by?
- practice
- complexity of S1
- compatibility of S-R
def: temporary storage of spatial info(dog remembering what a log is after its front legs go over it and it can’t see it anymore)
spatial working memory
