Chapter 9- Motivation
Chapter 5: Motivation
Definition of Motivation
Motivation is the process of arousing and sustaining goal-directed behavior.
Contemporary Explanation of Motivation
Instinct Theory
Drive Reduction Theory
Hierarchy of Needs
Instinct Theory
Instinct is described as a complex behavior that must have a fixed pattern throughout a species and is unlearned.
Drive Reduction Theory
A physiological need creates an aroused state that drives the organism to reduce the need (e.g., eating or drinking).
People are pushed by their needs and pulled by incentives, which are positive or negative environmental stimuli that motivate behavior.
Hierarchy of Needs
Maslow's pyramid of human needs:
Begins with physiological needs at the base.
Higher-level needs like safety and psychological needs become active after basic physiological needs are satisfied.
Hunger Motivation
Physiology of Hunger
The stomach contracts every time hunger is felt.
Body chemistry and the brain play pivotal roles in hunger.
Body Chemistry
Appetite Hormones:
Insulin: Hormone secreted by the pancreas that controls blood sugar levels.
Leptin: Protein secreted by fat cells that increases metabolism and decreases hunger when abundant.
Orexin: Hunger-triggering hormone secreted by the hypothalamus.
Ghrelin: Hormone secreted by empty stomachs signaling "I'm hungry."
PYY: Digestive tract hormone that signals "I'm not hungry."
The Brain and Hunger
The hypothalamus is key in controlling hunger:
Lateral Hypothalamus: Stimulating this makes well-fed animals start eating; if destroyed, starving animals show no interest in food.
Ventromedial Hypothalamus: Stimulating this area stops eating; destruction leads to rapid food processing by the stomach and intestines.
Psychology of Hunger
Eating patterns influenced by time.
Psychological influences on eating are evident, especially in cases of eating disorders, where the desire to remain thin overpowers homeostatic pressures.
Sexual Motivation
Recognized as an inherent part of life.
Sexual Response Cycle
Excitement Phase
Plateau Phase

Work Motivation
Groups of Motivational Theories
Internal: Suggests individual variables give rise to motivation (e.g., Maslow’s hierarchy of needs).
Process: Emphasizes interaction between the individual and the environment (e.g., Expectancy theory).
External: Focuses on environmental factors explaining behavior (e.g., Two-factor theory).
Early Philosophers of Motivational Theories
Max Weber: Work contributes to salvation; Protestant work ethic.
Sigmund Freud: Explored the unconscious mind to understand motives and needs.
Adam Smith: Enlightened self-interest benefiting individuals and society.

Motivation Factors: Related to the satisfaction of psychological growth; leads to enhanced performance and effort.
Motivation-Hygiene Theory of Motivation
Hygiene Factors prevent job dissatisfaction.
Motivation Factors enhance job satisfaction.
Individual—Organizational Exchange Relationship
Involves both individual contributions and organizational demands; a balance is sought between personal growth and organizational goals.
Adams’s Theory of Inequity
Inequity arises when a person perceives they are receiving less or giving more than others, leading to dissatisfaction.
Social Exchange Theory
Equity is determined by comparing outcomes and inputs between individuals.
Strategies for Resolution of Inequity
Adjust outcomes or inputs, alter comparisons used, rationalize inequity, or exit the situation.
New Perspectives on Equity Theory
Equity Sensitive: Preference for an equal equity ratio compared to others.
Benevolent: Comfortable when receiving less than others.
Entitled: Comfortable when receiving more than others.
Expectancy Theory of Motivation
Key Constructs:
Valence: Importance of reward
Expectancy: Belief effort correlates to performance
Instrumentality: Belief performance correlates to rewards
Expectancy Model of Motivation
Effort leads to performance, which leads to rewards, influenced by perceived relationships between effort, performance, and value of rewards.
Causes of Motivational Problems
Belief that effort won't yield performance.
Belief that performance won't yield rewards.
Value placed on or preference for certain rewards.
Moral Maturity
Measure of cognitive moral development; mature individuals act based on universal ethical principles, while immature individuals act egocentrically.
Chapter 5: Motivation
Definition of Motivation
Motivation is the psychological process that initiates, guides, and maintains goal-directed behaviors. It is influenced by various internal and external factors that stimulate action and inspire persistence towards achieving specific objectives.
Contemporary Explanation of Motivation
Motivation can be understood through several prominent theories:
Instinct Theory: This theory posits that certain behaviors are innate, driven by biological instincts that are universal across a species. These instincts result in predictable responses to specific stimuli without prior learning.
Drive Reduction Theory: According to this theory, physiological needs create a state of tension (drive) that compels organisms to engage in behaviors to restore balance. For example, hunger drives an individual to seek food, while thirst drives one to seek water. This theory emphasizes the interplay between need and the surrounding environment, suggesting that motivation is a consequence of biological imbalance and the pursuit of homeostasis.
Hierarchy of Needs: Proposed by Abraham Maslow, this theory presents a pyramid of human needs arranged in a hierarchy, from the most basic physiological needs at the base to higher-level needs such as self-actualization at the top. Needs must be satisfied in sequence, with lower needs dominating behavior until sufficiently met.
Hunger Motivation
Physiology of Hunger
The physiological basis of hunger involves intricate mechanisms:
Stomach Contraction: The feeling of hunger is often linked to stomach contractions.
Body Chemistry: Various chemicals and hormones play significant roles in regulating hunger and satiety. For example, when blood sugar levels drop, they trigger hunger signals.
Body Chemistry
Appetite Hormones:
Insulin: A hormone produced by the pancreas that helps regulate glucose levels and is crucial in energy metabolism.
Leptin: Secreted by fat cells, leptin informs the brain about energy reserves, promoting fullness.
Orexin: A hormone associated with stimulating appetite, secreted by the hypothalamus.
Ghrelin: Often termed the "hunger hormone," it is secreted by an empty stomach and signals the need for food.
PYY: This hormone is released by the intestines in response to eating, signaling satiety to the brain.
The Brain and Hunger
Central to hunger regulation are the hypothalamic regions:
Lateral Hypothalamus: Activation stimulates eating behaviors. If damaged, individuals may lose interest in food.
Ventromedial Hypothalamus: Stimulation here suppresses hunger. Its destruction can lead to excessive eating and obesity due to constant hunger signals.
Psychology of Hunger
Psychological factors also significantly influence eating behaviors, such as food cues, emotional states, and cultural practices, which can contribute to disordered eating patterns.
Sexual Motivation
Sexual motivation is regarded as a vital element of human behavior, influenced by biological, psychological, and sociocultural factors.
Sexual Response Cycle
The sexual response cycle consists of four phases:
Excitement Phase: Physical arousal begins, characterized by increased heart rate and blood flow.
Plateau Phase: A period of heightened arousal leading to orgasm; physiological responses reach their peak.
Orgasm Phase: The climax of sexual experience, marked by intense pleasure and release of sexual tension.
Resolution Phase: The body returns to its resting state, involving a decrease in sexual arousal.
Refractory Period: A time where further sexual stimulation fails to elicit a response following orgasm, varying in length among individuals.
Sexual Disorders
Sexual disorders can manifest in various forms, such as erectile dysfunction or lack of sexual desire, which can stem from psychological, physiological, or relational issues.
Hormones and Sexual Behavior
Sex hormones, including estrogen and testosterone, play crucial roles in sexual development and drive. These hormones influence not just physical attributes but also behavioral aspects of sexuality.
Psychology of Sex
The sexual behavior of individuals is also shaped by social and cultural contexts, family upbringing, societal values, and personal experiences.
Work Motivation
Understanding work motivation involves examining different theories that explain why individuals pursue certain goals in their professional lives.
Groups of Motivational Theories
Internal Theories: Focus on individual characteristics and their intrinsic motivators, like Maslow's hierarchy.
Process Theories: Explore interactions between individual choices and environmental factors, exemplified by Expectancy Theory.
External Theories: Emphasize the role of external stimuli and conditions impacting motivation, including the Two-Factor Theory.
Early Philosophers of Motivational Theories
Max Weber: Linked work to moral and spiritual motives, emphasizing the value of hard work in achieving personal salvation.
Sigmund Freud: Investigated subconscious drives and motivations affecting behaviors and needs.
Adam Smith: Advocated the benefit of self-interest in contributing to societal welfare through the invisible hand of the market.
Frederick Taylor: Introduced principles of scientific management, focusing on efficiency and cooperation to optimize productivity.
Maslow's Hierarchy of Needs
Maslow categorized human needs into a five-tier model, including:
Physiological Needs: Basic survival needs such as food, water, and sleep.
Safety & Security Needs: Protection from physical harm and financial stability.
Love and Belonging Needs: Emotional connections and relationships.
Esteem Needs: Recognition, self-respect, and respect from others.
Self-actualization: Realizing personal potential and self-fulfillment.
Motivational Theories X & Y
Theory X: Assumes employees are inherently lazy and require control and supervision.
Theory Y: Suggests employees are self-motivated and seek fulfillment through their work.
McGregor’s Assumptions
Based on Theory X: Individuals are inherently unmotivated and need to be tightly managed.
Based on Theory Y: Emphasizes the importance of developing motivation through positive engagement and empowerment.
Alderfer's ERG Theory
Alderfer condensed Maslow's needs into three categories:
Existence Needs: Basic survival and material needs.
Relatedness Needs: Social connections and interpersonal relationships.
Growth Needs: The desire for personal development and self-actualization.
McClelland’s Need Theory
McClelland identified three primary needs that drive motivation in the workplace:
Need for Achievement: The desire to excel and succeed against standards.
Need for Power: The urge to influence and control others.
Need for Affiliation: The importance of forming close social bonds and relationships.
Self-actualization and Motivational Need Theories
Self-actualization is central to motivational theories, primarily reflected in Maslow's, Alderfer's, and McClelland's formulations, which highlight the journey toward realizing one's full potential.
Herzberg’s Two-Factor Theory
Herzberg distinguished between:
Hygiene Factors: Conditions leading to workplace dissatisfaction, such as company policies and salary.
Motivational Factors: Factors that lead to job satisfaction and motivation, including achievement and recognition.
Motivation-Hygiene Theory of Motivation
To achieve job satisfaction, organizations must address both hygiene factors to prevent dissatisfaction and motivational factors to enhance satisfaction and performance.
Individual—Organizational Exchange Relationship
This dynamic involves the contributions of individuals toward their organization, balanced against the demands and expectations placed upon them. Successful organizations facilitate personal growth while achieving their goals.
Adams’s Theory of Inequity
Adams's theory posits that perceived inequities can lead to decreased motivation. When individuals feel they are receiving less or contributing more than others, motivational levels decline.
Social Exchange Theory
This theory suggests that individuals evaluate their relationships based on perceived equity, wherein they compare their inputs and outcomes against those of others.
Strategies for Resolution of Inequity
Adjusting inputs or outcomes, altering comparisons, rationalizing perceived inequities, or exiting the situation to achieve balance.
New Perspectives on Equity Theory
Equity Sensitive: Preference for a balanced equity ratio.
Benevolent: Comfort in receiving less than others and valuing fairness.
Entitled: Preference for receiving more than others and feeling justified in such perceptions.
Expectancy Theory of Motivation
Core components include:
Valence: The significance of the anticipated reward.
Expectancy: The belief that effort will lead to acceptable performance.
Instrumentality: The belief that successful performance will result in rewards.
Expectancy Model of Motivation
Effort leads to performance, and performance leads to rewards, with perceptions of relationships affecting this cycle.
Causes of Motivational Problems
Beliefs regarding the efficacy of efforts, correlation between performance and desired outcomes, and value assigned to specific rewards can all contribute to low motivation levels.
Moral Maturity
A measure of cognitive moral development; individuals with high moral maturity make decisions based on universal ethical principles, whereas those with lower maturity may act primarily in self-interest.
Overall, understanding motivation requires an appreciation of the complex interplay of biological, psychological, social, and contextual factors that drive human behavior.
