attention

Question 1

attention definition

Answer 1

focusing on certain aspects of environment

Question 2

arousal definition

Answer 2

wakefulness and sleepiness. global level of paying attention to the world

Question 3

consciousness definition

Answer 3

thinking about thinking.

Question 4

effort

Answer 4

with effort comes a shift in attention. close relationship btwn attention and effort

Question 5

2 arguments as to why we have attention

Answer 5

1. lots coming in and bottle necking before the processing can all be done
2. lots coming in and bottle necking after the processing

Question 6

what is perceptual load

Answer 6

total pool that can be divided in variety of ways.

Question 7

attention vs motor behaviour

Answer 7

attention improves performance

Question 8

what are the orgins of attentional shifts

Answer 8

overt and covert

Question 9

what is overt attention shift

Answer 9

eye movements track to where we are attendin in the world

Question 10

what is covert attention shift

Answer 10

shift in attention but havent shifted eye movement. paying attention to diff aspects but maintaining visual focus

Question 11

what is endogenous attention

Answer 11

you decide to consciously shift attention and move your eyes

Question 12

exogenous attention

Answer 12

when a salient stimuli happens in the environment (think flashing lights)

Question 13

voluntary attention

Answer 13

same as endogenous. deciding to shift your attention

Question 14

reflexive attention

Answer 14

same as exogenous. having your attention shift due to an outside stimulus

Question 15

top down attention

Answer 15

driven by internal environment

Question 16

bottom up environment

Answer 16

driven by environmental things

Question 17

consequences of attention large scale

Answer 17

neurons that are in the area are firing differently

Question 18

large scale mechanisms of attention

Answer 18

other areas assist in how we shift attention

Question 19

large scale tagets of attention

Answer 19

neurons that fire differently

Question 20

sources of large scale attention

Answer 20

areas that guide our attention

Question 21

what is attention in a basic way

Answer 21

some neurons might be more sensitive to some things, like if there is smth specific in the environment that youre looking for

Question 22

consequences of attention at a small scale

Answer 22

intracellular reporting. at low levels of stimulation there is increase of overall base level of firing, neurons become less sensitive for things that are irelevant to the stimuli, and as a person attends to a specific stimuli some neurons will change their prefrence.

Question 23

synchrony in attention

Answer 23

GABA will sometimes take unsynchronized neurons and sync them so that they fire on the same neuron at the same time

Question 24

the pulvinar

Answer 24

thalamus and pulvinar nucleus. connects visual cortex with other areas.

Question 25

frontal eye fields

Answer 25

top down guidance of movement. can cause shifts in attention even if eye movements do not occur.

Question 26

cicada

Answer 26

eye shifts

Question 27

lateral intraparietal area

Answer 27

guides attention, top down and bottom up

Question 28

right temporoparietal junction

Answer 28

lobes named after the bones above them, not by function. often see that activity will cross the borders

Question 29

dorsal frontoparietal system

Answer 29

cog control of voluntary attention

Question 30

right tempoparietal system

Answer 30

reflexive capture of attention. exogenously controlled attention

Question 31

simultagnosia

Answer 31

cant see everything when there are lots of things happening at the same time. for ex can see lots of letter T but cant see that theyre formed to make the letter G.
