A decrease in ones perception of a stimulus whose intensity has not changed due to higher neural inhibition is

a. habituation.

b. convergence.

c. divergence.

d. Adaptation

e. Illusion

Habituation.

Explanation:

Habituation may be defined as a form of simple learning in which the innate response of an individual perception decreases after repeated stimulation. Some components of organisms are involved in the habituation learning.

The individual response towards a particular stimulus decreases if the same stimuli is repeated over again and again or the stimulus of same intensity. Neural inhibition maintains the stimulus intensity.

Thus, the correct answer is option (a).
