Introduction to Psychology,
Objectives, Goals
Psychology is also concerned about how members of groups are influenced by
other members, as well as by the group norms, values, rituals and practices of
particular groups. It also emphasises on leadership and group formation etc.,
which can contribute to the field of sociology. Sociology has gained a lot from
psychology.
Psychological theories have contributed considerably to explain the origin and
survival of social customs and institutions. Theories of learning, perception and
motivation, have contributed to the development of sociology. Sociology has
also gained a lot from methods of research, developed by psychologists. Moreover,
sociology has widely used measurement techniques, such as, attitude scales,
interaction analysis etc., developed by psychologists.

Psychology and Economics
Economics deals with the economic organisation of society like income,
expenditure, the role of economic institution etc. Much of human behaviour can
be called economic behaviour. Economic theories have for long, considered the
role of psychological factors in economic behaviour. Thus, Mill and Bentham
advanced the theory of economic utilitarianism. Subsequently, the role of
psychological factors in economic activities has attracted the attention of many
thinkers. In recent years, McLelland and his associates have stressed the role of
what is known as the achievement motivation, in economic behaviour.
On the other hand, the economic structure of society and economic factors like
income, facilities etc. have been found to influence behaviour. Psychologists
have been interested in the analysis of the influence of economic factors like
income, on the development of behaviour. The role of poverty and economic
deprivation on the development of behaviour has been extensively studied by.
Psychologists. They speak of the proverbial ‘middle class child’ and his
characteristic behaviour like ambitiousness, high anxiety etc. Thus, psychology
is also closely related to economics.
