Chapter 8, Problem 1E

Summary Introduction

Introduction: A perceptual set is a mental tendency to perceive one thing and not the other. It can be achieved through experiences, expectations, and assumptions that can influence what one perceives. The perceptual adaptation is the capability to adjust to the changed sensory input including an artificially displaced or even inverted visual field.

Answer to Problem 1E

Correct answer: Sensation is the stimulation of the sense organs; perception is the sorting out, interpretation, analysis, and integration of stimuli by the sense organs and the brain.

Explanation of Solution

The sensory organs are stimulated by different stimuli. These stimuli are then converted into sensations by sense organs. These sensations are transmitted to the concerned parts of the brain. At last, the brain will interpret these sensations. The sensation is the ability of a body to detect both internal and external stimulations. The process of interpreting and recognizing sensory stimuli is called as perception. It allows a person to identify meaningful objects and events. It also helps a person to respond to the information. The perception involves mainly five stages, namely stimulation, organization, interpretation–evaluation, memory, and recall. The two main processes involved in the sensation and perception are bottom-up processing and top-down processing.
