Study Area 9 Motivation and Emotion Motivation Motivation: the process by which activities are started, directed, and continued so that physical or psychological needs or wants are met
extrinsic motivation: a person performs an action because it leads to an outcome that is separate from or external to the person intrinsic motivation: a person performs an action because the act is fun, challenging, or satisfying in an internal manner Instinct Approaches to Motivation
Instincts: the biologically determined and innate patterns of behavior that exist in both people and animals Instinct approach: approach to motivation that assumes people are governed by instincts similar to those of animals Drive-Reduction Theory of Motivation
the first theory for motivation Drive theories of motivation are based on the concept of drives, which are hypothetical states of tension or discomfort that motivate (or drive) an organism to engage in behaviors that will maintain a state of physiological stability (homeostasis). The theories have been influential but also have limitations, in that they
do not necessarily provide an adequate explanation for all types of behavior. Drive-Reduction Theory of Motivation Drive-reduction theory: assumes behavior arises from physiological needs that cause internal drives to push the organism to satisfy the need and reduce tension and arousal
Drive-Reduction Theory of Motivation Note: While the drive-reduction theory of motivation was once a dominant force in psychology, it is largely ignored today. Despite this, it is worthwhile for students to learn more about Hulls ideas in order to understand the effect his work had on psychology and to
see how other theorists responded by proposing their own theories. Need: a requirement of some material (such as food or water) that is essential for survival of the organism Drive: a psychological tension and physical arousal arising when there is a need that motivates the organism to act in order to fulfill
the need and reduce the tension Drive-Reduction Theory of Motivation Primary drives: involve needs of the body such as hunger and thirst Acquired (secondary) drives: learned through experience or conditioning, such as the need for money or social approval
Homeostasis: the tendency of the body to maintain a steady state Homeostasis In homeostasis, the body maintains balance in the bodys physical states. For example, this diagram shows how increased hunger (a state of imbalance) prompts a person to eat. Eating increases the level of glucose (blood sugar), causing the feelings of hunger to reduce. After a period without eating, the
glucose levels become low enough to stimulate the hunger drive once again, and the entire cycle is repeated. Three Types of Needs Need for achievement (nAch): involves a strong desire to succeed in attaining goalsnot only realistic ones, but also challenging ones Need for affiliation (nAff): the need for friendly
social interactions and relationships with others Need for power (nPow): the need to have control or influence over others McClelland's Human Motivation Theory is also known as Three Needs Theory, Acquired Needs Theory, Motivational Needs Theory, and Learned Needs Theory. Arousal Approach to Motivation
Stimulus motive: a motive that appears to be unlearned but causes an increase in stimulation, such as curiosity Arousal theory: theory of motivation in which people are said to have an optimal (best or ideal) level of tension that they seek to maintain by increasing or decreasing stimulation
Arousal Approach to Motivation Yerkes-Dodson law: law stating performance is related to arousal; moderate levels of arousal lead to better performance than do levels of arousal that are too low or too high This effect varies with the difficulty of the task easy tasks require a high-moderate level
more difficult tasks require a low-moderate level Arousal and Performance The optimal level of arousal for task performance depends on the difficulty of the task. We generally perform easy tasks well if we are at a highmoderate level of arousal (green) and accomplish difficult tasks well if we are at a low moderate level (red).
Arousal Approach to Motivation Sensation seeker: one who needs more arousal than the average person. Sensation seeking is a personality trait defined by the search for experiences and feelings, that are "varied, novel, complex and intense", and by the readiness to "take physical, social, legal, and financial risks for the sake of such experiences."
Incentive Approaches to Motivation Incentives: things that attract or lure people into action Incentive approaches: theories of motivation in which behavior is explained as a response to the external stimulus and its rewarding properties
Maslows Hierarchy of Needs Self-actualization: the point at which people have sufficiently satisfied the lower needs and achieved their full human potential - seldom reached Peak experiences: times
in a persons life during which self-actualization is temporarily achieved Drive-Reduction Theory of Motivation expanded Maslow's hierarchy of needs
Maslows Hierarchy of Needs Maslow proposed that human beings must fulfill the more basic needs, such as physical and security needs, before being able to fulfill the higher needs of selfactualization and transcendence. Self-Determination Theory of Motivation Self-determination theory (SDT): the social context of an action has an effect on the type of motivation
existing for the action. Concerns people's inherent growth tendencies and innate psychological needs. It is concerned with the motivation behind choices people make without external influence and interference. Intrinsic motivation: type of motivation in which a person performs an action because the act itself is rewarding or satisfying in some internal manner
Hunger: Bodily Causes Insulin and glucagon: hormones secreted by the pancreas to control levels of fats, proteins, and carbohydrates in the bloodstream insulin reduces the level of glucose in the bloodstream glucagon increases the level of glucose in the
bloodstream Leptin: hormone that signals the hypothalamus that the body has had enough food and reduces the appetite while increasing the feeling of being full Hunger: Bodily Causes Hypothalamus plays role in hunger responds to levels of glucose & insulin in the body
leptin: hormone that signals the hypothalamus that the body has had enough food and reduces the appetite while increasing the feeling of being full Obese Laboratory Rat The rat on the left has reached a high level of obesity because its ventromedial hypothalamus has been deliberately damaged in the laboratory. The result is a rat that no longer receives signals of being
satiated, and so the rat continues to eat and eat and eat. Hunger: Bodily Causes Weight set point: the particular level of weight that the body tries to maintain Basal metabolic rate (BMR): the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that
the digestive system is inactive, which requires about twelve hours of fasting). ... Basal Metabolic Rate (BMR); the number of calories you'd burn if you stayed in bed all day. BMR decreases with age and with the loss of lean body mass. Daily Calorie Needs are based on your activity level.
BMR The Harris Benedict Equation is a formula that uses your BMR and then applies an activity factor to determine your total daily energy expenditure (calories). The only factor omitted by the Harris Benedict Equation is lean body mass. Remember, leaner bodies need more calories than less leaner ones.
Hunger: Social Causes Social cues for when meals are to be eaten Cultural customs Food preferences Use of food as a comfort device or escape from unpleasantness Some people may respond to the anticipation of
eating by producing an insulin response Obesity Obesity: the body weight of a person is 20 percent or more over the ideal body weight for that persons height (actual percents vary across definitions) biological causes include heredity, hormones,
and slowing metabolism with age overeating is a major factor as food supplies stabilize in developing countries and Westernculture lifestyles are adopted Obesity BMI is a person's weight in kilograms (kg) divided by his or her height in meters squared. The National Institutes of Health (NIH) now defines normal weight, overweight, & obesity according
to BMI rather than the traditional height/weight charts. Obesity BMI is a person's weight in kilograms (kg) divided by his or her height in meters squared. The National Institutes of Health (NIH) now defines normal weight, overweight, & obesity according to BMI rather than the traditional height/weight charts.
Elements of Emotion Emotion: the feeling aspect of consciousness characterized by: certain physical arousal certain behavior that reveals the emotion to the outside world inner awareness of feelings Emotion, in everyday speech, is any relatively brief conscious
experience characterized by intense mental activity and a high degree of pleasure or displeasure. Scientific discourse has drifted to other meanings and there is no consensus on a definition. Emotion is often intertwined with mood, temperament, personality, disposition, and motivation. Elements of Emotion Which parts of the brain are involved
in various aspects of emotion? The amygdala the amygdala is a complex structure with many different nuclei and subdivisions, whose roles have been investigated primarily through studies of fear conditioning emotional stimuli travel to the
amygdala by both a fast, crude low road (subcortical) and a slower but more involved cortical high road The Low Road and High Road When we are exposed to an emotion-provoking stimulus (such as a shark), the neural signals travel by two pathways to the amygdala. The low road is the pathway underneath the cortex and is a faster, simpler path, allowing for quick responses to the stimulus, sometimes before we are consciously aware of the nature of the stimulus. The high road uses cortical pathways and is slower and more complex, but it allows us to recognize the threat and, when needed, take more conscious control of our emotional responses. In this particular example, the low road shouts, Danger! and we react before the high road says, Its a shark!
Elements of Emotion Which parts of the brain are involved in various aspects of emotion? other subcortical and cortical areas hemisphere
frontal lobes anterior cingulate cortex lateral orbitofrontal cortex; Emotion Psychological research has classified six facial expressions which correspond to six distinct universal emotions:
disgust, sadness, happiness, fear, anger, and surprise Facial Expressions of Emotion
Facial expressions appear to be universal. For example, these faces are consistently interpreted as showing (a) anger, (b) fear, (c) disgust, (d) happiness, (e) surprise, and (f) sadness by people of various cultures from all over the world. Although the situations that cause these emotions may differ from culture to culture, the expression of particular emotions remains strikingly the same. Facial expressions appear to be universal. Which of the six basic expressions is this?
Its disgusting. Facial expressions appear to be universal. Which of the six basic expressions is this? Its happy time. Facial expressions appear to be universal.
Which of the six basic expressions is this? Its fear. Facial expressions appear to be universal. Which of the six basic expressions is this? Its surprising.
Facial expressions appear to be universal. Which of the six basic expressions is this? Its sad. Facial expressions appear to be universal. Which of the six basic expressions is this?
I am angry. Elements of Emotion Facial expressions can vary across different cultures - people from different cultures perceive happy, sad or angry facial expressions in unique ways, according to new research published by the American Psychological Association.
Have been thought to be universal display rules - although facial expressions are pretty universal across the world, emotional display rules, in terms of how much emotion you should express, tend to vary greatly across cultures. Labeling Emotion Interpreting the subjective feeling by giving it a label
Theories of Emotion Common Sense Theory of Emotion Common sense theory of emotion: a stimulus leads to an emotion, which then leads to bodily arousal
James-Lange Theory of Emotion James-Lange theory of emotion: a physiological reaction leads to the labeling of an emotion Cannon-Bard Theory of Emotion Cannon-Bard theory of emotion: the physiological reaction and the emotion are
assumed to occur at the same time Cognitive Arousal Theory of Emotion Cognitive arousal theory: both the physical arousal and the labeling of that arousal based on cues from the environment must occur before the emotion is experienced Schachter and Singers cognitive arousal theory is similar to the James-Lange theory but adds the element of
cognitive labeling of the arousal. In this theory, a stimulus leads to both bodily arousal and the labeling of that arousal (based on the surrounding context), which leads to the experience and labeling of the emotional reaction. Facial Feedback Hypothesis Facial feedback hypothesis: facial expressions provide feedback to the brain concerning the emotion being expressed, which in turn causes and intensifies the emotion
In the facial feedback theory of emotion, a stimulus such as this snarling dog causes arousal and a facial expression. The facial expression then provides feedback to the brain about the emotion. The brain then interprets the emotion and may also intensify it. Cognitive Mediational Theory Cognitive-mediational theory: a stimulus must be interpreted (appraised) by a person in order to result in
a physical response and an emotional reaction In Lazaruss cognitive-mediational theory of emotion, a stimulus causes an immediate appraisal (e.g., The dog is snarling and not behind a fence, so this is dangerous). The cognitive appraisal results in an emotional response, which is then followed by the appropriate bodily response. Comparison of Theories of Emotion
