Name 4 categories of attention
alertness/arousal, vigilance(sustained attention), selective attention, resources (capacity)
most basic level of attention, helps in extracting information from the environment or to select a particular response
Describe vigilance
also called sustained attention, ability to maintain alertness continuously over time
Selective attention
selection of information essential to task
effort that is required to process information
Multiple resource theory
limited set of resources can be applied to specific processes. For example, spatial and verbal processes rely on different resources
Name brain structures involved in attention
1.reticular activating system(cell bodies are located in brain stem)
2.superior colliculus in midbrain
3.thalamus (subcortical and cortical)
4.parietal lobe
5.anterior cingulate cortex
6.frontal lobe
Reticular activating system
responsible for alerting and arousal, also controls sleep wake cycles, diffuse connections across cortex, contributes to sustained attention
What happens when RAS is damaged
contingent negative variation, long slow going negative shift ini brains electrical activity
Superior colliculus function
moving attention from one position to another
