The document discusses several theories of motivation and job satisfaction and their relationship to performance. It covers:
1) Performance is a function of ability and motivation according to several theorists. High motivation coupled with high ability leads to high performance.
2) Job satisfaction theories include need fulfillment theory, Herzberg's two-factor theory distinguishing satisfiers and dissatisfiers, and expectancy theory linking motivation to anticipated outcomes.
3) The theories suggest that unsatisfied needs stimulate motivation, which can lead to both high and low performance depending on other factors like ability. Satisfied needs activate new needs, while job satisfaction and its relationship to performance is complex with many moderating variables.
