Document Summary
Motivation is the force that drives behaviour. Emotion can be described as the intensity and quality of that force. Freud believed in two basic needs (internal states) which intensified until satisfied. He originally proposed that these were sex and self-preservation, then later changed these to sex and aggression. Contemporary theorists have added the need for relatedness and self-esteem. They have also focused on wishes as a desired state associated with pleasant feelings and on fears as an undesired state associated with unpleasant feelings. Primary drives such as hunger, thirst, sex etc. If these needs are unsatisfied, we develop internal tension (a drive) which motivates our behaviour to satisfy the need. Once the need is satisfied the drive is reduced and we return to a state of balance. Secondary drives are based on conditioning and modelling. Essentially, if an otherwise neutral stimulus becomes associated with a drive reduction (which reduces the internal tension) then the behaviour will be repeated.
