Information processing Flashcards
what occurs during preparation?
- recognition and interpretation of sensory stimuli
- planning and organization
What occurs during planning and organization? (6)
1 - postural preparation
2 - prep of limb movement
3 - prep of movement for object control
4 - prep for sequence of movements
5 - rhythmicity prep
6 - spatial coding
stabilization occurs in what step of a plan?
postural prep
direction, trajectory, and accuracy considerations occur in what step of a plan?
prep of limb movement
force control and end state comfort are considered in what step of a plan?
prep of object control
orientation in space is considered in what step of a plan?
spatial coding
what are the two theoretical approaches to movement prep?
information processing and perception-action coupling
what are the three stages of info processing?
input, decision making, and execution
input stage
stimulus identification
- perceive/interpret input situational factors
decision making
response selection
- compare with existing memory stores and make decisions
execution
response programming
- organize and execute selected response
____________ suggests perceptual processes traverse a series of mental processes, linked with memory and influenced by arousal, and results in a decision to act.
expanded information processing model
in ______ environment and task are perceived or interpreted directly based on affordances
perception action coupling
affordances
action possibilities of environment and task in relation perceiver’s capabilities
what does perception action coupling emphasize?
- emerging interaction between the performer and the environment
- coordination of perceptual and motor systems
- organization of action is specific to the task and environment
what does perception action coupling de-emphasize?
the need for stored representations
as the learner gains experience perceptual variables couple with the dynamics of the movement so that a distinct coordination patter can be ______________
- reproduced and modified as necessary
response time is comprised of_________________
reaction time and movement time
reaction time occurs when?
from stimulus presentation to initiation of movement
movement time occurs when?
from initiation of movement to completion of movement
reaction time is comprised of _____________
premotor and motor time
premotor time occurs when?
between stimulus presentation and onset of EMG
motor time occurs when?
from onset of EMG to initiation of movement
What are some factors that affect reaction time?
- number of choice responses
- age and pathology
- experience and practice
- task complexity
- anticipation
- stimulus-response compatibility
- attentional demands
