Document Summary

Motivation: a process that influences the direction persistence and vigour of goal-directed behaviour. Instinct: is an inherited predisposition to behave in a specific and predictable way when exposed to a particular stimulus: have a genetic basis, do not depend on learning and have survival value for an organism. Human instinct theories faded due to little evidence to support it. Homeostasis: a state of internal physiological equilibrium that the body strives to maintain: requires a sensory mechanism for detecting changes in the internal environment, control center functions like a thermostate. Once fixed at a set point the sensors detect changes. Drive theory of motivation: physiological disruptions to homeostasis produce drives, state of internal tension that motivate an organism to behave in ways that reduce the tension: drives e. g. hunger and thirst. Incentives: represent enviormental stimuli that pull the organism toward a goal. Incentive theories focus attention on external stimuli: proposes that goal directed behaviour is jointly determined by two factors.
