Motivation: process that influences direction, persistence and vigour or goal directed behaviour. Darwin"s theory of evolution inspired views that instincts motivate our behaviour. Instinct: inherited predisposition to behave in a specific and predictable way when exposed to particular stimulus. Genetic basis and found universal among all members of species, do not depend on learning and have survival value for organism. Human instinct theories have little evidence and rely on circular reasoning. By conducting twin and adoption studies, behaviour geneticist establish how strongly heredity accounts for differences among people in many aspects of motivated behaviour.
