Chapter 6: Visual Attention

Question 1

attention

Answer 1

the process of focusing on specific objects while ignorning others

Question 2

attentional capture

Answer 2

when the properties of a stimulus grab attention, seemingly against a person’s will

Question 3

covert attention

Answer 3

attention that you maintain without looking at the object

Question 4

fixiation

Answer 4

when you briefly pause to process/recognize information

Question 5

overt attention

Answer 5

attention that involves looking directly at the attended object

Question 6

saccadic eye movement

Answer 6

a rapid jerky movement from one fixiation to another

Question 7

visual salience

Answer 7

scene regions that are markedly different from their surroundings (like in color, contrast, movement, or orientation)

Question 8

visual scanning

Question 9

precueing

Answer 9

determine whether presenting a cue indicating where a test stimulus will appear enhances the processing of the test stimulus

Question 11

saliency map

Answer 11

reveals which regions are visually different from the rest of the scene

Question 12

visual search

Answer 12

when we look for an object among a number of other objects

Question 13

same-object advantage

Answer 13

the faster responding that occurs whene enhancement spreads within an object

Question 15

local field potential (LEP)

Question 16

spatial attention

Question 17

change blindness

Answer 17

rensink - showed a picture, blank screen, picture with object missing, blank screen, and orginal picture (multiple times). Found that there was a difficulting in detecting changes in scenes

Question 18

continuity errors

Answer 18

aspects of a scene that should have maintained constant change from one shot to the next.

Question 19

dual task procedure

Question 20

inattentional blindness

Answer 20

subjects can be unaware of clearly visibke stimuli if they arent directing their attention to them (Mack and Rock)

Question 21

balint’s syndrome

Answer 21

characterized by an inablity to focus and shift attention when multiple objects are present in a scene

Question 22

binding

Answer 22

the process by which visual features are combined to create our perception of a coherent object

Question 23

binding problem

Answer 23

how an object’s individual features become bound together

Question 24

conjunction search

Answer 24

searching for a conjunction of two features in a stimulus

Question 25

dishabituation

Question 26

divided attention

Answer 26

people need to complete multiple tasks at once

Question 27

feature integration theory (FIT)

Question 28

feature search

Question 29

habituation

Question 30

focus attention stage

Question 31

high load tasks

Question 32

illusory conjunctions

Answer 32

combinations of features from different stimuli (shown a small red triangle and small green circle, might say you saw a small green triangle)

Question 33

load theory of attention

Question 34

low load tasts

Question 35

perceptual capacity

Question 36

perceptual completion

Question 37

perceptual load

Question 38

preattentive stage

Answer 38

occurs before we focus attention on an object - automatic, unconcious, and effortless

Question 39

task-irrelevant stimuli
