One reason sensory adaptation can be beneficial is that it allows us to:
A) ignore continuous stimuli and shift our focus and attention to other events.
B) detect visual stimuli outside of the normal visual spectrum.
C) locate the source of sounds in the environment.
D) convert physical and chemical stimuli into nerve impulses.
Answer: A
Rationale: Sensory adaptation is the reduction of activity in sensory receptors with continued exposure to a stimulus. Because of sensory adaptation, we experience ongoing stimuli less intensely, which allows us to focus on other events which are possibly more important.
