Lecture 11 - Attention Flashcards
What parts of the brain are involved in attention?
pulvinar nuclei of the thalamus; frontal eyefields (i.e., BA 8); primary sensory areas, reticular system, cingulate gyrus, frontoparietal dorsal route; temporal ventral areas
In attention, the ____ hemisphere is more important than the _____ hemisphere.
right; left
Where is attention located?
brainstem, cortex, subcortical gray and white matter
In attention, the endogeneous system is
goal-directed, focused, top-down and dorsal
In attention, the exogeneous system is
used when needed, bottom-up, ventral, and is working when stimuli is novel
Language is ____ in the brain, whereas attention is ____
localized; dispersed
Which part of the brain does executive functioning occur?
ventral prefrontal area
Overt attention is _____
paying attention solely to one thing)
Covert attention is ____
paying attention to one thing while other items are allowed into your sphere of focus.
What is required to pay attention?
executive function (i.e., inhibition, interference, planning, set/task shifting) and working memory (both visuospatial and auditory)
What do people with ADHD have trouble with?
planning, inhibition, and working memory
What do people with ADHD not have trouble with?
set/task shifting and interference
What is early selection?
(humans perceive something, store it quickly, and then decide to keep it in a buffer or discard it).
What is late selection?
Humans perceive something, determine what it is via semantics and then decide what information we want to process or not).
What is leakage?
when certain information is allowed into the sphere of attention
What is slippage?
when certain information slips into your sphere of focus; this is covert attention
What are implications for the early selection view of attention?
we select the information we focus on, analyze what we perceive, and reject all other information.
What are implications for the late selection view of attention?
you perceive all information that you’ve decided to pay attention to; semantics is involved; we are consciously aware of what we are paying attention to
_______ cause greater amplitude in ERP than ________
attended stimuli; unattended stimuli
Endogenous system overlaps with which area of the visual system?
where is it or dorsal area
Exogenous system overlaps with which area of the visual system?
what is it or the ventral area; occipital-temporal-frontal
