A child, with the assistance of its parents, starts recognising things around him. He starts developing his own vocabulary and, within a short time, starts identifying the objects correctly. He can recognise a car as a car, a cow as a cow, a TV as a TV, a shop selling ice cream, etc. The children of these days are even smarter; they are able to operate a TV, a tape recorder, a VCR, etc., which were unheard of by an adult some 15 years ago.

We can judge the capacity and capability of the human brain if a child can correctly recognise everyday objects, even as more and more new objects are introduced. It assigns different meanings to different objects and helps to differentiate clearly between two types, two classes, or two families of objects.

The number of products that are being introduced into the market is increasing day by day. These products were designed to meet basic and higher needs, as well as some that were designed to meet very minor human needs. People can clearly identify the product or recognise the class or family to which the product belongs.

The degree to which the product is recognised depends on several factors: the person's value system, cultural background, relationship with the product, environment, and other demographic and psychographic factors related to the person recognising the product.
