Topic 6: Habituation

Question 1

Habituation

Answer 1

The diminishing of physiological or emotional response to a frequently repeated stimulus. Diminishing of response will take place over many trials

Question 2

Principle #1

Answer 2

Response to a stimulus decreases and gets progressively smaller

Question 3

Principle #2

Answer 3

After a time, habituation disappears and response is no longer observed

Question 4

Principle #3

Answer 4

More intense responses, often the result of more intense stimuli, are slower to habituate

Question 5

Principle #4

Answer 5

Habituation can be overlearned, where the stimulus does not produce a response

Question 6

Principle #5

Answer 6

We habituate faster the second time

Question 7

Is habituation faster or slower when stimuli causes a higher startle response?

Answer 7

Slower

Question 8

Is habituation faster or slower when stimuli are repeated more often?

Answer 8

Faster

Question 9

Is habituation faster or slower when stimuli are presented more closely together?

Answer 9

Faster

Question 10

Habituation paradigm

Answer 10

Recognition of this stimulus is inferred if the visual fixation time to this stimulus increases: this is the dishabituation phase.

Question 11

Neural habituation in Aplysia

Answer 11

• Habituation occurs early in the neural chain
• Reduction of amount of glutamate released from presynaptic neuron
• Used as a model for complex neural systems.
