Some of the observable traits include the following: Facial/audible expression of distress: clenching of teeth, moaning and sighing and being easily irritable. Wolfe et al. (2012), started a quest to understand the relation between electrical signals in the nervous system and perception. He stated that the messages from our sense organs are a series of brief impulses that are very alike, whether the message is meant to arouse the sensation of light, touch or pain. If they are closely crowded the sensation is intense and if separated by long intervals the sensation is correspondingly feeble.

Stimuli refer to the outside environment that we are close to and what arouses our receptors. Electrical signals are created by the receptors and sent to the brain. What follows is recognition and action which involves perceiving and reacting to the stimuli. There are however two types of stimuli i.e. that within the environment and the one within the person’s body (Pinel, 2011).

The signal that reaches the nervous system is actually transformed from the original signal although it still represents the original signal. This transformation is achieved through neural processing whereby the original electrical representation of the stimulus that is created by the receptors is transformed by processing into a new representation by the brain stimulus.

Sensations are elementary experiences evoked by sensory stimulation such as the sourness of lemon juice. these primitive sensations combine to create perceptions. The principle of perception is based on several principles i.e. the principle of transformation which states that the stimuli and responses created by the stimuli are changed between the stimuli in the environment and the perception.
