CHAPTER 12 (SUMMARY): MOTIVATION AND WORK Overview Motivation is a need or desire that energizes and directs behavior. The early view that instincts control behavior was replaced by drive-reduction theory, which maintains that physiological needs create psychological drives that seek to restore internal stability, or homeostasis. In addition, some motivated behaviors increase arousal, and we are pulled by external incentives. According to Maslow, some motives are more compelling than others. Hunger seems to originate from changes in glucose and insulin levels that are monitored by the hypothalamus, as well as changes in the levels of leptin, orexin, and PYY. To maintain a set- point weight, the body also adjusts its basal metabolic rate. Body chemistry and environmental factors together influence our taste preferences. Psychological influences on eating behavior are most evident in those who are motivated to be abnormally thin. Like hunger, sexual motivation depends on the interplay of internal and external stimuli. In nonhuman animals, hormones help stimulate sexual activity. In humans, they influence sexual behavior more loosely. One’s sexual orientation seems neither willfully chosen nor willfully changed; new research links sexual orientation to biological factors. The need to belong, is a major influence in motivating human behavior. Social bonds boosted our ancestors’ survival rates. We experience our need to belong when feeling the gloom of loneliness or joy of love, and when seeking social acceptance. Work meets several human needs. The growing field of industrial-organizational psychology attempts to match people to work, enhance employee satisfaction and productivity, and explore strategies for effective workplace management. People who excel are often self-disciplined individuals with strong achievement motivation. Effective leaders build on people’s strengths, work with them to set specific and challenging goals, and adapt their leadership style to the situation. Motivational Concepts Defining motivation; Theories of motivated behavior. A motivation is a need or desire that serves to energize behavior and to direct it toward a goal. Under Darwin’s influence, early theorists viewed behavior as being controlled by biological forces, such as instincts. When it became clear that people were naming, not explaining, various behaviors by calling them instincts, this approach fell into disfavor. The idea that genes predispose species-typical behavior is still influential in evolutionary psychology. Psychologists next turned to a drive-reduction theory of motivation. Most physiological needs create aroused psychological states that drive us to reduce or satisfy those needs. The aim of drive reduction is internal stability, or homeostasis. Furthermore, we are not only pushed by internal drives but we are also pulled by external incentives. Rather than reducing a physiological need or minimizing tension, some motivated behaviors increase arousal. Curiosity-driven behaviors, for example,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
