Psychology and Engineering
Human factors engineering, as a branch of applied psychology, has made
important contributions in the field of engineering. Industrial psychologists have
helped in designing the right type of machines which would make would make it
possible for the workers to do their best by eliminating unnecessary operations,
minimizing strain and eliminating possibilities of confusion and oversight. This
aspect of adjusting the job to the employee is known as human engineering.
Human engineering has played a major role in developing ultra-comfortable
automobiles, aircrafts, etc., in order to minimize stress strain and maximize
efficiency and work output.
Every industry depends on its ability to sell its products, not only for its survival
but also for its growth and expansion. Therefore, it is important to know the

needs, likes, dislikes, preferences and habits of people who buy these products.
In a watch company, the product in-charge for a new range of watches which
were believed to be exquisite, took informal feedback from their own friends
and peers within the company. What they omitted to do was to check formally
with consumers. They went ahead with production.
But, they had unsold inventory for many months because consumers rejected it,
the chief reason being difficulty in reading time on those beautiful dials.
Somewhere, in that quest to deliver cutting edge, perhaps, they had forgotten the
basics. This highlights the importance of consumer psychology, yet another branch
of psychology, which not only attempts to understand consumer needs and
preferences through consumer surveys, but also contributes in the field of
advertising. Effective advertisements help industries to influence consumers to
buy their products. Psychologists have been helping in designing advertisements
which would attract the attention of consumers and effectively convey the
messages so that they are motivated to buy the products.
