Midterm Motor Behavior Flashcards
what is “the ability to regulate or direct the mechanisms essential to movement”
motor control
- muscle activity is a response to a reflex
- reflex chain: peripheral stimulus sets off a reflex which in turn sets off another reflex, resulting in movement
reflex theory
- “top down” approach
- the higher level exhibits control over the lower levels
- based on Darwin’s theory of evolution
- CNS controls movements, which result from activation of muscle groups
- Assumes CNS maturation drives motor control & development
hierarchical
theorized that movement is not solely generated and located in the CNS
- movement depends on the internal and external forces acting upon the body
- the body is a mass which has a variety of forces and vectors acting upon it.
- control of movement is an action of a variety of systems working together
- output of the nervous system, filtered through the musculoskeletal system
systems theory
- “self organization”
- when a system of individual parts comes together, it’s elements behavior an ordered way.
- no need for “higher center” for organization
- variable that regulates change in the behavior of the entire system
- stable movement patterns become more variable right before transition to a new movement pattern
dynamic action theory
- environment drives motor control and behavior.
- behaviors are goal driven in a specific environment
- perception of the environmental factors surrounding a task
- use of perceptual information as feedback to adjust motor response
ecological theory
-nervous system focus
-layered networks with multiple elements
recovery is possible
parallel distribution theory
defined as a centrally located pattern which governs movement which does not require external sensory stimulation to produce a movement response
-not meant to be an exclusive theory
motor program theory
- normal movement emereges as a result of an interaction of many different systems which contribute different aspects of control
- movement is organized around a goal
- limitation in movement result from a failing of one or more systems
task orientated
set of processes associated with practice or experience leading to relatively permanent changes in the capability for producing skilled action
motor learning
-sensory feedback is used to control and refine a movement.
adam’s closed-loop theory
movement is initiated by _____ trace and ____takes over to perform movement and detect error
memory
perceptual
-developed to address the limitations of Adam’s closed loop theory
-motor programs are not specific, but general rules for a type of movement
-individual leans general rules which are applied to different situations
emphasis on open-loop control
Schmidt’s schema theroy
abstract representation stored in memory following multiple presentations of a class of object
schema
what gets stored in schema theory?
initial movement conditions
parameters for general motor program
outcome of the movement
sensory consequences
- every time we make a movement, we make a memory of that movement outcome
- when we make a similar movement, we continue to make memories about that specific movement and compare it to other similar movements
- by repeatedly doing this, we create rules and parameters for doing movements
recall schema
sensory conditions of a previous moevment are used with the initial conditions to predict the sensory consequences
-we use the outcome of that movement and analysis of the situation to make future movements
recognition schema
two unrelated stimuli, association
classical conditioning
behavior due to a stimulus-response; if positive: increase stimulus. if negative response: decrease stimulus
operant conditioning
what are the areas of the brain which are active during operant conditioning
deep cerebellar nuclei (movement)
amygdala (emotions)
lateral dorsal premotor area of cortex (integration of sensation with movement)
learning tasks that van be performed automatically without attention or conscious thought, like a habit
stored in the stratum of basal ganglia
procedural learning
what is stage is learner in:
- learner is trying to understand the task
- lots of attention
- performance is variable
cognitive
what is stage is the learner in:
- best strategy selected
- refinement of skill
- performance is streamlined
- weighing of explicit vs. implicit strategies
associative
what stage is the learner in:
automatic
least amount attention needed
autonomous
