attention
involves a process of selection where the performer juggles several ongoing lines of thinking, with each competing for current resources in our consciousness (James, 1890)
attention capacity: 2 types
dealing with overload capacity
input stimulus identification response selection movement programming output
stimulus identification phase and interference
the stroop effect
“the cocktail party effect”
-dichotic listening task: 2 stimuli presented at the same time
out ability to focus on one conversation in an environment that is loud or noisy with many things potentially competing for our attention
sustained attention
what affects our sustained attention
(military research) fighter plane
controlled processing
automatic processing
automaticity is the result of
an enormous amount of practice
types of skills and automacity
-what is the relationship between processing and then following types of skill?
closed skill: predictable environment- automatic processing would be easier because you know all the info in advance ex) diving
open skill: unpredictable environment
how can we develop automacity? 2 ways
-requires practice, lots and lots of practice!
-will it occur quickly? No
2 ways:
1. Consistent mapping- ex) the red light means stop
2. Varied mapping – ex) button layouts on different brands of TV remotes
movement programming
delayed movement response
-psychological refractory period
movement response is interrupted movement response is re-organized- and is now successful
focus of attention 2 ways:
the inverted U-principle
arousal- the level of excitement produced under stress
—————————————————————–
sleep state extremely alert
-can it have an impact on performance? Yes especially when speed and accuracy is a crucial factor
-perceptual narrowing: it is the tendency for the perceptual field to shrink under stress with high arousal
choking under pressure
