Wanting and doing-> we do things we want to do (usually to get something we want) Moti(cid:448)atio(cid:374): a(cid:374)(cid:455) (cid:272)o(cid:374)ditio(cid:374) that i(cid:374)itiates, a(cid:272)ti(cid:448)ates or (cid:373)ai(cid:374)tai(cid:374)s a(cid:374) orga(cid:374)is(cid:373)"s goal- directed behaviour: usually an internal condition: inner state that energizes and directs us and keeps us moving towards our goals. Evolutionary theories: claims that human behaviour is motivated by instincts. These instincts have a functional purpose around the continuation of the species. Hu(cid:373)a(cid:374)s are less (cid:862)hard (cid:449)ired(cid:863) tha(cid:374) other species. Drive theories: internal state of tension (drive) that motivates organism to engage in behaviours that reduce this tension. Because organisms attempt to seek homeostasis (hunger for example-> the drive of hunger leads us to the motivation to get food to stop feeling hungry) Problems: people can have motivations without a drive arousal of any sort (we do not.
