Document Summary

Psychology 1000: chapter 10 motivation and emotion. Motivation: a process that influences the direction, persistence, and vigour of goal-directed behaviour. Instinct theory and evolutionary psychology: instincts motivate much of our behaviour. Instinct: an inherited predisposition to behave in a specific and predictable way when exposed to a particular stimulus. Homeostasis and drive theory: the body"s biological systems are delicately balanced to ensure survival. Homeostasis: a state of internal physiological equilibrium that the body strives to maintain. Requires a sensory mechanism for detecting changes in the internal environment. Requires a response system that can restore equilibrium. A control centre that receives information from the sensors and activates the response system: functions like a thermostat. Drive theory: physiological disruptions to homeostasis produce drives. Drives: states of internal tension that motivate an organism to behave in ways that reduce this tension. Incentive and expectancy theories: pulls an organism toward a goal.
