Document Summary

Proposes that biological needs or deficiencies increase our drive or arousal level. Probability of acting is the product of habit strength and drive level: habit strength refers to how habitual an action is. Not all needs are biological in nature. When your needs are met but you still have drive (you"re full but you still want dessert) When your needs are not met but you don"t have any drive (you"re hungry but you really dislike what mom made) Missing incentive: anticipated reward learned through past experience: after hall"s theory, many incentive-based theories came out, drive theories look at how internal states push you whereas incentive theories look at how external stimuli pull you. When arousal is too high or too low we try to obtain an optimal level: contrast to hall: we don"t want 0 arousal just a good medium . Arousal increases/decreases with drugs and other stimuli. Diurnal variations: time of day influencing your level of arousal.
