Your senses provide informatin about the ? and ?
internal and external environment
Components of Sensory experience:
1) Stimulus
2) Reception
3) Perception
What is a Stimuli/stimulus?
anything that stimulates a nerve receptor
What is Reception?
-process of receiving stimuli from nerve endings in the skin and inside the body
-receptor converts a stimulus to a nerve impulse
What is Perception?
Ability to interpret the impulses transmitted from the receptors and give meaning to the stimuli.
Perception of a stimulus is affected by several factors:

-require sensory stimulation to grow and develop
-exposure to voices, music, ambient noise develops auditory NS
-light color contrast allow infant to observe work in which they live
Sensory Functions in Older adults:
-experience a generalized decrease in the # of nerve conduction fibers (slower reflexes, delayed response)
-structural changes in eye and ear
-sensory decline may cause withdrawl, depression, social isolation, hallucinations

Explain previous experience in sensory response:
prior experience with a stimulus informs our response to same stimulus
