Theories of motivation

At a simple level, it seems obvious that people do things, such as go to work, in order to get stuff they want and to avoid stuff they don't want.

Why exactly they want what they do and don't want what they don't is still something a mystery. It's a black box and it hasn't been fully penetrated.

Overall, the basic perspective on motivation looks something like this:

In other words, you have certain needs or wants (these terms will be used interchangeably), and this causes you to do certain things (behavior), which satisfy those needs (satisfaction), and this can then change which needs/wants are primary (either intensifying certain ones, or allowing you to move on to other ones).

A variation on this model, particularly appropriate from an experimenter's or manager's point of view, would be to add a box labeled "reward" between "behavior" and "satisfaction". So that subjects (or employees), who have certain needs do certain things (behavior), which then get them rewards set up by the experimenter or manager (such as raises or bonuses), which satisfy the needs, and so on.

Classifying Needs

People seem to have different wants. This is fortunate, because in markets this creates the very desirable situation where, because you value stuff that I have but you don't, and I value stuff that you have that I don't, we can trade in such a way that we are both happier as a result.

But it also means we need to try to get a handle on the whole variety of needs and who has them in order to begin to understand how to design organizations that maximize productivity.

Part of what a theory of motivation tries to do is explain and predict who has which wants. This turns out to be exceedingly difficult.

Many theories posit a hierarchy of needs, in which the needs at the bottom are the most urgent and need to be satisfied before attention can be paid to the others.

1. Maslow's hierarchy of need

2. Alderfer's ERG theory

3. Acquired Needs Theory (mcclellan)

4. Cognitive Evaluation Theory

5. Two Factor theory (Herzberg)

6. Equity Theory

7. Reinforcement Theory

8. Expectancy Theory (Vroom)
