Habituation vs. Sensitization

NEURO-B3CKCQ

In Aplysia, the sea snail, an automatic reflex behavior is heavily studied by neuroscientists: the touch of Aplysia​’s siphon causes its gill to withdraw. Using this reflex, researchers have investigated habituation, sensitization, as well as the molecular basis of learning and memory.

Which of the following is INCORRECT about habituation and sensitization?

A

Habituation occurs when the siphon touch is repeated, and the amplitude of the withdrawal response decreases.

B

Sensitization occurs when the researchers pair siphon touch with an electrical shock, and this pairing makes the gill withdrawal larger.

C

Habituation and sensitization are types of non-associative implicit memories.

D

Sensitization can occur with non-noxious or non-painful stimuli too.
