Week2 Flashcards
apperceptive agnosia
impaired early vision,
unable copy- draw images
associative agnosia
early vision (perception) seems intact,
the inability to name objects is attributed to a later stage of recognition and
categorization.
aphantasia
inability to engage in mental imagery
endogenous (or central) cue
engages
voluntary attention and can appear in between the potential target
locations and indicate symbolically where the target is likely to
exogenous (or peripheral) cue
engages reflexive
attention and can appear at one of the target locations instead of in between them.

*(no left/right preference)
*Meaning affects figure-ground segmentation

Broadbent’s Filter Model of Attention (1958)
Attenuation Model (“Leaky filter”)
Treisman` attention model
cocktail party effect
Load Theory of Attention
Nilli Lavie
high load -No recources left, so
no distraction by
irrelevant stimuli
Low Perceptual Load- Recources left, so
easily distracted by
irrelevant information
Spatial Attention
overt - covert attention
Overt attention
spatial attention by moving the eyes
eye movement responses: saccade latency/saccade end-point/fixation
duration
Covert attention
spatial attention without moving eyes
manual responses: reaction time/accuracy/d-prime
mental spotlight
