In pioneering research with the sea slug Aplysia,Kandel and colleagues demonstrated that,when lightly touched,Aplysia would withdraw its gill.With repeated touches,however,the gill withdrawal lessens,demonstrating:
A)classical conditioning.
B)habituation.
C)operant conditioning.
D)sensitization.

Question

Quizplus · Accepted Answer

The phenomenon described in the question is habituation, which is a simple form of learning where an organism's response to a repeated stimulus decreases over time. In this case, the repeated touches to the Aplysia's gill caused the withdrawal response to lessen, indicating habituation. Classical conditioning involves pairing a neutral stimulus with a biologically significant stimulus to elicit a specific response, operant conditioning involves learning through consequences or rewards, and sensitization involves an increase in response to a stimulus after repeated exposure.
