Simple Forms & Perceptual Learning And Memory

Question 0

Acoustic startle reflex

Answer 0

A defensive response to a loud unexpected noise.

Question 1

Habituation

Answer 1

A decrease in the strength or occurrence of a behavior after repeated exposure to the stimulus that produces the behavior.

Question 2

What is the process of habituation?

Answer 2

Decreasing behavior

Question 3

Factors influencing habituation:

Answer 3

Stimulus specific
Time sensitive
Spontaneous recovery

Question 4

Stimulus specific

Answer 4

Habituation to one event does not cause habituation to every other stimulus in the same modality

Question 5

The less arousing an event is the more rapidly a response to that event will habituate

Answer 5

Stimulus specific

Question 6

Stimulus exposures that are repeated closely together in time

Answer 6

Massed exposures

Question 7

Stimulus exposures that are spread out over time

Answer 7

Spaced exposures

Question 8

Spontaneous recovery

Answer 8

The reappearance or increase in strength of a habituated response after a period of no stimulus presentation

Question 9

Orienting response

Answer 9

Natural reaction to a novel stimulus

Question 10

Dishabituation

Answer 10

Recovery of the behavioral response to a new stimulus

Question 11

Sensitization

Answer 11

Experiences with an arousing stimulus lead to stronger responses to a later stimulus

Question 12

What is the process of sensitization?

Answer 12

Increase in response which occurs only after an emotional stimulus

Question 13

Factors influences sensitization:

Answer 13

Emotional intensity and timing

Question 14

Sensitization is not stimulus specific

Answer 14

True

Question 15

What is perceptual learning?

Answer 15

Learning in which repeated experiences with a set of stimuli makes more stimuli easier to distinguish. (Wine tasting) Stimulus specific.

Question 16

Mere exposure learning

Answer 16

Repeated exposure causes to be able to see a difference

Question 17

Habituation in Aplysia

Answer 17

Synaptic depression

Decrease in glutamate

Question 18

Sensitization in Aplysia

Answer 18

Increase in glutamate (LTP)

Question 19

Categorical perception

Answer 19

Our ability to classify stimuli into discrete categories that vary along a continuum of the given stimulus dimension

Question 20

Prior exposure to a stimulus affects a response to that stimulus later

Answer 20

Priming

Question 21

Cortical plasticity

Answer 21

Receptive maps are able to be rewired through practice

Question 22

Cells that fire together wire together

Answer 22

LTP

Question 23

Cells out of sync loose their link

Answer 23

LTD

Answer 24

Habituation

Question 25

LTP is

Answer 25

Sensitization
