Expectancy Theory of Motivation: Motivating by Altering Expectations
Fred C. Lunenburg
Sam Houston State University ________________________________________________________________________ ABSTRACT Vroom’s expectancy theory differs from the content theories of Maslow, Alderfer, Herzberg, and McClelland in that Vroom’s expectancy theory does not provide specific suggestions on what motivates organization members. Instead, Vroom’s theory provides a process of cognitive variables that reflects individual differences in work motivation. From a management standpoint, the expectancy theory has some important implications for motivating employees. It identifies several important things that can be done to motivate employees by altering the person’s effort-to-performance expectancy, performance-to-reward expectancy, and reward valences. ________________________________________________________________________
Need theories of motivation (Alderfer, 1972; Herzberg, 1968; Maslow, 1970; McClelland, 1976) attempt to explain what motivates people in the workplace. Expectancy theory is more concerned with the cognitive antecedents that go into motivation and the way they relate to each other. That is, expectancy theory is a cognitive process theory of motivation that is based on the idea that people believe there are relationships between the effort they put forth at work, the performance they achieve from that effort, and the rewards they receive from their effort and performance. In other words, people will be motivated if they believe that strong effort will lead to good performance and good performance will lead to desired rewards. Victor Vroom (1964) was the first to develop an expectancy theory with direct application to work settings, which was later expanded and refined by Porter and Lawler (1968) and others (Pinder, 1987). Expectancy theory is based on four assumptions
