ch 4-attention

Question 1

broadbents filter model

Answer 1

your sensory memory holds info for a fraction of a second and then your filter identifies physical characteristics of attended messages and filters out others then of detectors process the meaning of attended messages and out put is send to STM

Question 2

attenuation model

Answer 2

addition of attenuator (analyzes incoming messages) and dictionary unit (contains thresholds for words) to the broadbent model

Question 3

late selection model

Answer 3

most of incoming information is processed to the level of meaning before the message oto be further processed s selected

Question 4

stimulus salience

Answer 4

physical properties of the stimulus- bottom up processing

Question 5

saliency map

Answer 5

determining physical characteristics at each scene and location and combine

Question 6

Micheal posner

Answer 6

used precueing to determine whether paying attention to a location improves a person’s ability to respond to a stimuli presented

Question 7

divided attention

Answer 7

achieved with automatic processing

Question 8

binding

Answer 8

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

Question 9

Feature Integration Theory

Answer 9

proposed by Anne Treisman-we use a preattentive stage to analyze features then combine features in a focused attention stage that then leads to our perception

Question 10

illusory conjunctions

Answer 10

one object can take on properties of another object

Question 11

ventral vs dorsal attention networks

Answer 11

ventral- controls attention based on salience (bottom up)

dorsal- controls attention based on top down processing

Question 12

effective connectivity

Answer 12

how easily activity can travel along a particular path
