Perception is the interpretation of stimuli from surrounding environment. Perception may be the thought of as bringing the past to bear on the present so that the present make sense. A person who is already experienced an event may be able to recognize patterns of that event that a person who is inexperienced cannot detect. Mental schema is generally built through perceptual process which intern helps in cognition. Training may be useful in order to provide schemas that are consistent with a product (Bailey, 1996). Perception may be defined as integration of information that is provided by the senses in order to make sense of the world (Boff and Linclon, 1988). Thus, perceptual organization is ‘the process by which we apprehend particular relationships among potentially separate stimulus elements (e.g. parts, features, dimensions).’

As we could sense different products by means of different senses, perception can be divided into five kinds viz. visual perception, auditory perception, touch related perception, smell perception, and the perception of taste. Examples of different types of perception are presented below in the Table 2.
