Document Summary

Motivation: process that influences persistence, direction, and vigour or goal directed behaviour. Predisposition to act in a certain way to certain stimulus. State of internal physiological equilibrium that the body strives to. Sensory mechanism for detecting changes in internal environment. Control system (activates response system) think of furnace or maintain thermostat: once at a set point it activates response. Drives internal tension that motivate an organism to behave in ways that reduce this: e. g) hunger, sex, thirst, sleep. Reducing drives is the goal of motivation (hull) Regulatory drives: preserves homeostasis (hunger, thirst, oxygen) Central state theory: different drives correspond to neural activity in different set of neurons in the brain. Central drive system: set of neurons in which activity falls underlie. External stimuli stimuli with high incentive can motivate behaviour without biological need similar to classical conditioning. Expectancy x value: goal directed behaviour is determined by: strength of expectation and value of the goal (incentive value)
