CH. 20 Attention Flashcards
attention
the prioritization of some mental or neural phenomena over others,
including sensory input and behavioral response.
posner cueing task
a task that aims to measure behavioral differences between
endogenous and exogenous attention through the difference in reaction times to
central and peripheral cues.
endogenous attention
prioritization that is primarily due to an internal (to the
mind or brain) source.
exogenous attention
prioritization that is primarily due to an external (to the
mind or brain) source.
top-down attention
prioritization that benefits from prefrontal feedback.
bottom-up attention
prioritization that is primarily driven by the sensory cortices
inattentional blindness
the failure to notice a stimulus that is clearly visible in normal conditions due to an attention-involving task.
spotlight metaphor
attention is likened to a spotlight being cast over a stage; intimately connected to the theater metaphor for conscious experience.
binding problem
determining the neural mechanism by which sensory features
that are processed separately in the brain are bound into unified objects.
