Sensation is a process in which a sensory receptor is stimulated producing nerve impulses that travel to the brain. It is the process of receiving signals from external stimuli through sense organs and paying attention to them. Sense organs are the ear, eyes, nose, tongue, and skin.
The individual receives sense in terms of vision, hearing, touch, smell, and taste. Individuals pay attention to stimuli and try to interpret such information. It shows an individual behavior and personality. In addition, there are six senses that generally make intuition on the basis of past experience.
Factors Affecting Sensation
There are three factors affecting sensation. They are;
Stimulus is the force that impacts sensing. There is internal and external stimulus. Internal stimuli are inside the body like muscles, digestive system, glands, etc. external stimuli are outside the body as heat, cold, sound, scene, etc. individual receives environmental information through sense organ which provides impact on internal stimulus.
Receptors are attached to the sense organs. They convert environmental information to neural events. Human beings uses specified receptor-like hearing receptors include hearing cell located in the inner ear, seeing receptors includes rods and cones located in the retina, and so on. They provide support to sense organs from seeing information received from the external environment.
c) Central Nervous System
It is responsible for integrating sensory information and responding accordingly. It consists of the spinal cord and brain. The spinal cord consists of several parts. It connects the brain and the main receptor and serves as a conductor for signals between the brain and the rest of the body. The brain is responsible for integrating most sensory information and coordinating body function, both consciously and unconsciously.
What kind of memory involves storage of brief events, such as sights, sounds, and tastes?

What has research by goolkasian & woodbury (2010) demonstrated about pattern perception?
A) Subliminal priming is more effective than priming above the absolute threshold.
B) Those who have a preexisting phobia will interpret innocuous patterns as threatening.
C) Those who receive less auditory priming are more likely to hear things than those who receive more auditory priming.
D) Those who are given verbal priming produce a biased interpretation of complex ambiguous figures.
