Attention Flashcards
attention
behavioral or cognitive process of concentrating on information, requires cognitive effort and is associated with consciousness or awareness
focused attention
ability to concentrate on a target stimulus
divided attention
ability to process different info and multitask
what is the main difference between brain areas required for focused vs divided attention
divided attention requires more pre-frontal cortex and parietal regions (because it requires more cognitive attention)
3 theories of attention
1 - bottleneck
2 - single resource pool
3 - multiple resource pool
bottleneck theory
- there is a continual flow of info that is impeded at some point by a filter that will decide what will be processed
- earliest theory
- doesn’t explain dual tasks
single resource theory
- we have one pool of attentional resources and can do more than one task if we don’t exceed our pools capacity
- capacity is influenced by level of arousal
multiple resource theory
- there are multiple attention mechanisms (resource pools) each related to a specific activity
4 resources pools of the multiple resource theory
1) input
2) output
3) stage of info processing
4) codes
* we are more able to multi task if we do things in different boxes
input = _______ processing
sensory
output = _________ processing
motor
stage of info processing concerns
perception, decision making, and execution
codes = ____________ processing
cognitive/memory
4 factors that influence attention demands
1 - environment and task complexity
2 - skill level of performed
3 - number of cues
4 - arousal
arousal
level of activation/excitement of a person’s CNS
