Detailed explanation-1: -Since the image of a person approaching grows larger in our eyes, why do we not perceive that person turning into a giant? We perceive that distance is decreasing. We unconsciously move our head to apply the motion parallax cue.
Detailed explanation-2: -Sensory-perceptual alteration can be defined as when there is a change in the pattern of sensory stimuli, followed by an abnormal response to such stimuli. Such perceptions could be increased, decreased, or distorted with the patient’s hearing, vision, touch sensation, smell, or kinesthetic responses to stimuli.
Detailed explanation-3: -The initial experience of a stimulus or an object registered by a particular sense organ is called sensation. It is a process through which we detect and encode a variety of physical stimuli.
Detailed explanation-4: -The difference threshold is the smallest difference in stimulation that can be detected 50 percent of the time. The difference threshold is sometimes called the just noticeable difference (jnd), and it depends on the strength of the stimulus.
Detailed explanation-5: -sensation, in neurology and psychology, any concrete, conscious experience resulting from stimulation of a specific sense organ, sensory nerve, or sensory area in the brain. The word is used in a more general sense to indicate the whole class of such experiences.
