Lecture 19 Flashcards
Perception, Action and Memory
Bernstein said that control of movements of a system with many degrees of freedom is very complex
he believes, control of such system is only possible if …
the system is continuously supervised by a sensory organ
what is a key word linked to Gibsons ideas
affordances
what is meant by affordances
in any organisms environment there are features (objects, places, other organisms) that offer potential opportunities for behaviour
what are affordances specific to
specific to individuals
humans can perceive features (objects, places, other organsims etc) as ….
humans can perceive these features as affordances for action
energy flows generated by our movement can be :
(and what do these mean) (2)
- invariant = constant
- variant = changing
movement context influences how we perceive information (what is direct perception)
if higher order variables can specify action
movement context influences how we perceive information (what is indirect perception)
if meanings / complex decisions are needed
what is memory and the benefit
the ability to recall things, which allows us to benefit from experience
what us short term memory
stored for only 20-30 seconds unless rehearsed
what is working memory
temporarily stores recently presented material
what can working memory do to long term storage of information
can retrieve information from long term storage to influence current problem solving, decision making and movement production
what is long term memory
memories that are relatively permanent
what is an approach that practitioners use to aid memory
present analogies of movement
ways we can get the learner to be able to modify technique
explicit (conscious)
implicit (subconscious
