What is the main difference between sensation and perception?

Sensation and perception are two terms for the same process.

Perception occurs at the receptor level, while sensation happens in the brain.

Perception is a term used for somatosensory stimuli, while sensation refers to visual stimuli.

Sensation involves the activation of sensory receptors, while perception involves the interpretation of sensory information by the brain. (correct)

Which of the following is NOT a type of sensory receptor adaptation?

Phasic adaptation

Tonic adaptation

Rapid adaptation

Sensory adaptation (correct)

Why are tonic receptors more suitable for detecting long-lasting stimuli?

They adapt rapidly to constant stimuli.

They maintain a constant response to a sustained stimulus. (correct)

They respond quickly to changes in stimulus intensity.

They are less sensitive to changes in stimulus quality.
