Document Summary

People are motivated to interact with their environments to maintain at least a minimum level of brain stimulation. Example: sensory deprivation study = no one could handle it (max 6 hours) Needed to have sensory stimulation to function = allows for behavior to go on. Drives play a role in behavior by motivating an organism to engage in a particular behaviour. We have stored up energy for different drives but once energy is gone there is no drive. Example: after drinking a l of water there is no more drive to drink more = flush model. Brain is storing energy for behavior = state of arousal motivates us to particular behavior. But drives, reinforcers, stimulation and motivation do not explain all behaviour. Neural activity gives rise to behaviour and this activity is influenced by evolution and the environment. We are born with irms that activate behaviour in response to templates within us.
