Which of the following best describes a behavior that occurs with repeated exposure to the same stimulus?

• A. Adaptation
• B. Habituation
• C. Conditioning
• D. Reflex

Answer: (B)

The concept of habituation refers to a decrease in response to a stimulus after repeated exposure. When an individual is repeatedly exposed to the same stimulus, such as a loud noise or a particular smell, they typically become less responsive to it over time. This is a fundamental form of learning, where the organism learns to ignore the stimulus because it is no longer perceived as a threat or important.

In contrast, adaptation refers to a sensory process where sensory receptors become less sensitive to constant stimuli. Conditioning involves the learning processes that pair a neutral stimulus with an unconditioned stimulus to elicit a response. A reflex is an automatic response to a stimulus that does not involve conscious thought. However, habituation specifically involves the gradual decline of response due to a stimulus being repeatedly presented, making it the correct choice in this context.
