attention, memory and learning Flashcards
what are peterson and posners 3 distinct networks for attention
alerting network
orientating network
dual executive network
Attention system is anatomically separate from the sensory systems that process incoming information and produce behaviors
-whose network of attention theory?
peterson and posner
Speeds up reaction & detection of stimuli (especially by enhancing function of prefrontal and posterior parietal regions)
-what network of attention?
alerting network
the alerting network of attentions key is ? from ? in the brain stem
adrenergic projection from locus coeruleus
in the alerting network of attention, activity get increased in what brain part?
anterior cingulate cortex and related structures
Prioritizes sensory input by selecting a sensory modality or location in space
-what network of attention is this?
orientating network
the orientating network is composed of 2 other networks. what are they?
dorsal orientating network and the ventral orientating network
Synchronizes visuo-spatial orienting in order to “lock on” to the attentional target.
-what network of attention?
dorsal orientating network
Involved in disengaging and shifting attention to new targets.
- what network of attention
ventral orientating network
frontoparietal system and cingulo-opercular system belong to what network of attention?
executive network
frontoparietal system does what?
Voluntary control of attention on moment-to-moment basis
cingulo-opercular system does what?
maintaining task set throughout a task
structures of the orientate network are? and the modulator is?
superior parietal temporal parietal frontal eye fields superior colliculus -- acetylcholine
structures of the alerting network are? and the modulator is?
locus coeruleas
right frontal
parietal cortex
–norepinephrine
structures of the executive network are? and the modulator is?
anterior cingulate lateral ventral prefrontal basal ganglia ---dopamine
The failure to notice an event that occurs while performing a task (e.g., “gorilla experiment”)
intentional blindness
Failure to notice changes in presence, identity, or location of objects in scenes
change blindness
5 models of memory (sensory modality based)
olfactive auditory gustative tactile visual
5 models of memory (content based)
memory for faces memory for objects memory for names spatial memory autiobiographical memory
3 models of memory (time based)
past (retrograde)
present (anterograde)
future (prospective)
3 models of memory (storage capacity based)
sensory short term (working) long term
short term memory is associated with processing on both ? and ?
dorsal (spatial/memory) and ventral streams (recognition)
