Final Flashcards
attention is the state of focused awareness on a ____ of available perceptual info
subset
three stages of attention
disengage - take attention away from current focus
shift - move attention from one item to another
engage - lock attentional focus onto a new item
voluntary selective attention
attention shifted between inputs intentionally
reflexive selective attention
shifts in attention occurring in response to an external event
overt attention
what you are DIRECTLY looking at (involves your eye movements)
covert attention
attention something that you are not directly looking at (not associated with eye movements)
is the cocktail party effect limited to auditory stimuli
no, works with visual stimuli too
endogenous control of attention
deliberately paying attention to something
exogenous control of attention
attention directed to something reflexively
what is emotion
an internal state and involuntary physiological response to an object or situation
two components of emotion
the physical sensation and the cognitive experience
what is affect
the conscious, subjective mental feeling about a stimulus coming from the self-monitoring of physiological changes and subjective cognitive states
posterior attentional system
the part of the frontoparietal attentional network concerned with orienting attention in space (where do we want to focus?)
anterior attentional system
the part of the frontoparietal attentional network concerned with the conscious control of attention to decide what stimuli you need to focus on?
vigilance system
the part of the frontoparietal attentional network concerned with the preparation and sustainment of alertness towards signals that demand high priority
parietal lobe is involved in this part of attention
the shifts of attention in space (where we are paying attention)
damage to this brain area in combination with deficits of this neurotransmitter may cause inability to maintain alert states/maintain vigilance
damage to the right frontal area and deficits in NE (depletion of NE in right hemisphere causes deficits in arousal and alertness)
inattentional blindness
a failure to notice or at least report a stimulus that would be easily reportable if you were paying attention
change blindness
a change in a visual stimulus that is introduced that the observer doesnt notice
difference between mood and emotion
emotion is more sudden and intense reactions whereas mood is more diffuse and tends to last longer
theory of constructed emotion
the brain anticipates what is upcoming to prepare accordingly to maintain allostasis (internal stability despite changing conditions)`
somatic marker hypothesis of emotion
emotion is the result of the change in the body following a stimulus, therefore reduced bodily response to a stimulus should result in reduced emotional intensity
neglect disorder (in attention)
the inability to attend to or respond to stimuli in the visual field opposite (contralesional) to that which has a lesion. typically the neglect of the left visual field after damage to the right parietal lobe. Patients end up neglecting the left side of their own body and world.
right hemisphere hypothesis of emotion
the right hemisphere is dominant for ALL emotions
