Going by Hull's drive-reduction theory, as stated in Psychology, by Ciccarelli, 4th edition:
A need is a requirement of some material (such as food or water) that is essential for survival of the organism. When an organism has a need, it leads to a psychological tension as well as a physical arousal that motivates the organism to act in order to fulfill the need and reduce the tension. This tension is called a drive (Hull, 1943).
In the abstract of Mahatoo's (1989) paper, "Motives must be Differentiated from Needs, Drives, Wants: Strategy Implications", the following is stated:
In a suggested model, motives are suggested as the specific motivational element that directs the consumer′s drive towards a particular response. Thus while needs generate the response tendency, motives determine the specific behavioural action.
What I'm inferring from these two sources of information is that:
1) Need is a physiological/psychological requirement
2) Drive is what propels the organism to eliminate imbalance
3) Motive is the course of action the organism takes when faced with a drive.
An example of point 3 could be the instance where a recuperating substance abuse addict feels the drive to relapse, they may not with the help of proper clinical intervention if their motive is to achieve sobriety.
My question: Am I correct? If not, I would appreciate it if you could post the correction, both for the differences and the example.
