cognitive psych:
reaction to behaviourism
way we percieve information, store it and then use it to solve problems rhrough experience learning and memory
basic concepts of psych:
brain recieves constant stream of info as electrical impulses from neurons
important info amplified by brain as action potentials
signals sent ot specific part of brain specialized to recieve that info
if its long enough signal to become even related potential brain gets body to act which cause muscle to contract
the science that studies how neural funcitons translate to mental and motor functions is_________
cognitive science
name some cognitive skills critical in sport
attention and anticipation
perception
decision making
problem solving
pattern recognition
memory
focus and concentration
perception
how we process sensory info in short period of time (100ms)
considered subconscious
objects can shift from perception to awareness
attention
how we select info for more extensive processing in threshols that range from 120-200ms depending on snesory modality
anticipation form of early attention
what are characteristics of attention?
primary and secondary attention
serial vs parallel processing
psychological refactoy period
bias and selective attention
anticipation (spatial vs temporal)
expert attention
what is the difference bwtween novice and experts in how a skill is performed?
novice need more focus on how to do a skill while experts can focus on external anvironment more because motor skills become automatic
what is a cross sectional study?
looking at different groups in one point of time
what is the stroop effect?
parallel streams of info processed by brain at same time
during stroop RT is slower and errors are greater
which part of brain is for word comprehension?
wernickes area
which part of brain is color vision?
occipital
explain psychological refactory period
delay in attention when 2 stimuli are processed close together
once we detect the 2nd stimulus we cant process it until we finish the 1st
even though S! and S2 may be 60-80 ms apart a delay of 200-300ms occurs in responding
what is anticipation?
ability to direct attention to a stimulus prior to its presentation
what are two types of anticipation?
spatial
temporal
spatial anticipation
predict what is going to happen before stimulus appears
ability to anticipate where in spcae movement will occur
ex being in position for a pass
temporal anticipation
predicting when a stimulus will appear
ex-timing attention and movement to be at right time and right place
what are the cognitive sub fields?
perception
attention
focus and concentration
memory
pattern recognition
problem solving
decision making
focus and concentration
ability to attend what is important with period of mental relaxation
memory
how info stored in the brain and we access it and use it as knowledge for controling thoughts and emotion
pattern recognition
ability ro racognize staionary and moving objects, as well as navigating in clutteres environment
problem solving
how we use perception attention and other cognitive abilities to arrive at a solution
decision making
how we chose from alternatives available to us
