Moivaional state/drive- reversible internal condiions that orient individual towards speciic type of goals . Ex. hunger (an internal state) moivates eaing (external acion) Regulatory drives help maintain physiological homeostasis (hunger, thirst, thermoregulaion), needed for immediate survival. Non-regulatory drive-fulill some other evoluionary purpose (reproducion, safety, cooperaion) indirectly contribute to survival. Safety (drives as sleep and fear that moivate us to replenish bodies and escape danger) Reproducive (sexual, maternal, sexual jealousy drives moivate us to reproduce, care for young, guard mates) Educaive (play and exploraion, moivates us to pracice skills and learn about environments) Describe the reward systems and mechanisms in the brain. Rewards = pleasure, which reinforces the moivated behaviour. Reinforce behaviour that results in reducion in drives (both regulatory and non-regulatory) Limbic system, paricularly basal forebrain (middle head, behind eyes)
