Document Summary

Motivation refers to a need or desire that energizes (effortful) behaviour and directs it towards a goal; combination of physiological and psychological processes. A fixed (rigid and predictable) pattern of behaviour observed across all members of the species. Not acquired by learning, typically rooted in genes. Does not involve ration decision making (cognition) A drive is an aroused/tense state related to a physical need that is not being met. Some strong human needs include: hunger, sex, and belonging. Shared among members of the species; something we have in common and related to our genetic backgrounds. Drive-reduction theory suggests that we are motivated to restore homeostasis when a drive emerges.

Incentive motivates by attracting the person to the reward as opposed to pushing the person (negative reinforcement)
