Incentive Theory
301 in review Concepts and Theories of Motivation THEORIES OF MOTIVATION Theory Main Points Instinct Innate biological instincts guide behavior. Drive reduction Behavior is guided by biological needs and learned ways of reducing drives arising from those needs. Arousal People seek to maintain an optimal level of physiological arousal, which differs from person to person. Maximum performance occurs at optimal arousal levels. Incentive Behavior is guided by the lure of rewards and the threat of punishment. Cognitive factors influence expectations of the value of various rewards and the likelihood of attaining them. ? 1. The fact that some people like roller coasters and other scary amusement park rides has been cited as evidence for the theory of motivation. 2. Evolutionary theories of motivation are modern outgrowths of theories. 3. The value of incentives can be affected by , , and factors. Wright et al., 1995). Underarousal, too, can cause problems, as you probably know if you have ever tried to work, drive, or study when you are sleepy. So we try to increase arousal when it is too low and to decrease it when it is too high. In simpler terms, we seek excitement when we’re bored and relaxation when we’re stressed or overstimulated. In general, we perform best, and may feel best, when arousal is moderate (Teigen, 1994), but people differ in the exact level of arousal that is optimal for them (Zuckerman, 1984). These differences in optimal arousal may stem from inherited differences in the nervous system (Bardo, Donohew, & Harrington, 1996; Berns et al., 2001; Eysenck, 1990a) and may motivate boldness, shyness, and many other personality traits and behavioral tendencies. Incentive Theory primary drives Drives that arise from basic biological needs. secondary drives Stimuli that take on the motivational properties of primary drives through learning. arousal A general level of activation reflected in several physiological systems. optimal arousal theory A theory that people are motivated to maintain what is, for them, an optimal level of arousal. incentive theory A theory that people are pulled toward behaviors that offer positive incentives and pushed away from behaviors associated with negative incentives. Instinct, drive reduction, and arousal theories of motivation all focus on internal processes that prompt people to behave in certain ways. In contrast, incentive theory emphasizes the role of external stimuli that motivate behavior. According to this view, people are pulled toward behaviors that offer positive incentives and pushed away from behaviors associated with negative incentives. In other words, differences in behavior from one person to another or from one situation to another can be traced to the incentives available and the value a person places on those incentives at the time. If you expect that some behavior (such as buying a lottery ticket) will lead to a valued outcome (winning money), you will be motivated to engage in that behavior. The value of incentives can be influenced by inborn physiological factors such as hunger and thirst, as well as by cognitive and social factors that gain their power through learning. As an example of physiological influences, consider that food is a more motivating incentive when you are hungry than when you’re full (Balleine & Dickinson, 1994). As for cognitive and social influences, notice that the value of some things we eat—such as communion wafers or diet shakes—isn’t determined by hunger or flavor but by what our culture has taught us about spirituality, health, or attractiveness. Perhaps you have also noticed that what early drive reduction theorists called primary drives reappear in incentive theory as unlearned influences on an incentive’s value. Secondary drives reappear as learned influences on the value of incentives. “In Review: Theories of Motivation” summarizes the theoretical approaches we have outlined. Each theory has helped to guide research on motivated behaviors such as eating, sex, and work, which we consider in the sections that follow.
