What We Review
Introduction
Motivation plays a vital role in guiding behavior and mental processes. It influences everyday decisions and drives people to seek or avoid specific outcomes. However, motivation itself can sometimes feel complicated. Researchers have proposed various theories to explain why individuals behave the way they do. Therefore, this article will explore some of the most common theories of motivation. It will break them down into easy-to-understand sections, followed by examples that show how these concepts appear in daily life.
First, the discussion outlines core motivation theories, including drive-reduction theory, arousal theory, self-determination theory, instinct theory, Lewin’s motivational conflicts theory, and sensation-seeking theory. Next, it explains the role of eating behaviors and belongingness in motivation. By the end, there is a quick reference chart to help clarify essential terms.
Theories of Motivation
A. Drive-Reduction Theory
Drive-reduction theory focuses on physical needs, such as hunger, thirst, or sleep. When a physical need is not satisfied, an internal state of tension, or a “drive,” develops. This drive motivates behaviors that attempt to restore balance, also known as homeostasis. Therefore, when a person experiences thirst, the drive-reduction theory would suggest that this sensation motivates the individual to drink water and reduce discomfort.
- Emphasizes the importance of balancing internal conditions (homeostasis).
- Suggests that behavior is often goal-directed toward fulfilling basic needs.
Example: Thirst and Drinking Water
- Identify a physical need: In this case, the physical need is feeling thirsty.
- Understand the drive to alleviate it: Thirst creates an internal drive to seek water.
- Explain how drinking water restores balance: Consuming water satisfies the thirst and returns the body to homeostasis.
Practice Problem:
Imagine a person who has not eaten all day. How would drive-reduction theory explain their behavior?
Step-by-Step Solution
- Recognize the physical need: Hunger is the unsatisfied physiological requirement.
- Identify the drive: The feeling of hunger becomes a strong drive that the person wants to reduce.
- Predict the behavior: The hungry individual seeks food to reduce the discomfort of hunger.
- Relate to homeostasis: Eating restores balance by satisfying the body’s energy needs.
B. Arousal Theory
Arousal theory suggests that people are motivated to maintain an optimal level of alertness or arousal. Individuals may increase or decrease stimulation to reach a level of comfort that aids performance. The Yerkes-Dodson Law states that moderate arousal levels can lead to optimal performance, while too little or too much stress can reduce effectiveness.
- Addresses how stress and stimulation affect performance.
- Emphasizes finding a balance in excitement or stimulation levels.

Example: Studying for an Exam
- Define the optimal level of arousal: Students often need moderate stress or interest to stay focused.
- Discuss how stress affects performance: Excessive anxiety might hinder concentration, while zero pressure could lead to procrastination.
- Apply it to studying scenarios: Setting realistic goals or deadlines helps maintain a moderate arousal level.
Practice Problem:
Two friends are preparing for a presentation. One of them feels extremely nervous, while the other is too relaxed. How does arousal theory suggest improving their performance?
Step-by-Step Solution
- Assess each friend’s arousal level: One is overly anxious, and the other is under-stimulated.
- Identify optimal arousal: The goal is to bring each person’s arousal to a moderate level.
- Adjust behavior: The anxious friend could practice calming techniques, and the relaxed friend could use a timer or set milestones to increase focus.
- Connect to performance: Once both reach moderate arousal, they are more likely to perform effectively.
C. Self-Determination Theory
Self-determination theory explains motivation as either intrinsic (coming from internal interest or enjoyment) or extrinsic (driven by outside rewards like money or recognition). This framework asserts that humans naturally strive for autonomy, competence, and a sense of relatedness to others. Therefore, when people adopt behaviors because they find them personally fulfilling, they tend to stay motivated longer.
- Differentiates between internal satisfaction and external rewards.
- Highlights the importance of individual interest and personal growth.
Example: Choosing a Hobby vs. Aiming for a Reward
- Identify intrinsic and extrinsic motivations: A person might choose a hobby because it is fun (intrinsic) or because it offers a prize (extrinsic).
- Compare the outcomes: Intrinsic motivation often leads to sustained engagement, while extrinsic motivation can fade if rewards stop.
- Discuss motivations behind a common activity: Some people love music just for joy, whereas others play to win competitions.
Practice Problem:
Consider a student who volunteers at an animal shelter because of a college scholarship requirement. How might self-determination theory suggest a deeper form of motivation?
Step-by-Step Solution
- Recognize the extrinsic motivation: Volunteering to meet a scholarship requirement is an external reward.
- Shift focus to intrinsic motivation: The student might discover a genuine love for caring for animals.
- Promote ongoing engagement: Realizing a personal passion can enhance willingness to volunteer beyond scholarship needs.
D. Instinct Theory
Instinct theory focuses on innate, fixed patterns of behavior that occur in animals, such as migration or nesting habits. Many non-human animals demonstrate instinctual behaviors triggered by specific cues. Humans do not appear to rely on strictly instinctual patterns. However, early theories once proposed that humans had universal instincts, an idea that has largely been revised by modern research.
- Centers on genetically determined behaviors in animals.
- Highlights that human behavior is more flexible than purely instinctual.
Example: Animal Migrations
- Define instinctual behavior: In some bird species, migration is prompted by external cues like daylight duration.
- Explore how animals exhibit instincts: Migratory birds follow instinctual routes without formal training.
- Discuss how this differs in human behavior: Humans learn most travel-related behaviors, relying more on experience and technology.
Practice Problem:
Give an example of a behavior sometimes mistaken for a human instinct and explain why it may not meet the criteria.
Step-by-Step Solution
- Choose a supposed human “instinct”: For instance, “survival instincts” like seeking shelter.
- Explain why it is not strictly an instinct: Humans learn various shelter-building or seeking methods.
- Highlight the role of learning: Cultural and social factors typically shape how people respond to such needs.
E. Lewin’s Motivational Conflicts Theory
Kurt Lewin’s motivational conflicts theory outlines how decision-making often involves conflicts that can motivate or discourage action. Three types of conflicts arise:
- Approach-approach conflict: Choosing between two appealing options.
- Avoidance-avoidance conflict: Deciding between two unpleasant choices.
- Approach-avoidance conflict: One choice has both positive and negative aspects.
Example: Deciding Between Two Colleges
- Define each type of conflict: Approach-approach (two good colleges), avoidance-avoidance (two unwanted tasks), approach-avoidance (one good college with a high tuition).
- Analyze the decision-making process: Students might compare scholarship offers, campus atmosphere, or location.
- Illustrate conflicts faced in decisions: A student chooses between a local college with flexible hours and a more prestigious but distant college.
Practice Problem:
A teenager must decide between spending a weekend studying (potentially boring) or working on a friend’s project (could be stressful). Which motivational conflict applies, and how might the individual resolve it?
Step-by-Step Solution
- Classify the conflict: This is an avoidance-avoidance conflict because both options are unappealing.
- Interpret the motivations: The teenager might dislike both boredom and stress.
- Suggest a resolution: By combining study time with short breaks, the individual could reduce the negative elements and make the decision less unpleasant.
F. Sensation-Seeking Theory
Sensation-seeking theory examines how people differ in their desire for novel or varied experiences. Some individuals thrive on thrill or adventure, while others prefer calm surroundings. Researchers indicate four main sensation-seeking categories: experience seeking, thrill or adventure seeking, disinhibition, and boredom susceptibility.
- Explains why some people enjoy extreme sports.
- Suggests different thresholds for risk and excitement.
Example: Extreme Sports Enthusiasts
- Explore different types of sensation-seeking: Some focus on new cultural experiences, while others chase physical thrills.
- Discuss the motivations for participating in extreme sports: Adrenaline and novelty can be highly rewarding.
- Examine the effects of boredom on behavior: Individuals with high boredom susceptibility may seek frequent, intense stimuli.
Practice Problem:
How does sensation-seeking theory explain a student who frequently changes hobbies or tries the newest craze?
Step-by-Step Solution
- Recognize the boredom aspect: Such a student likely has low tolerance for repetitive tasks.
- Identify their sensation-seeking style: They may be high in “experience seeking.”
- Connect to motivation: Trying new things keeps arousal levels high and fights boredom.
The Role of Eating and Belongingness in Motivation
A. Eating Behaviors
Eating is more than physical nourishment. It involves hormones, internal drives, and external factors. The hormones ghrelin and leptin regulate hunger and fullness. Ghrelin stimulates appetite, while leptin signals satiety. Social settings, habitual cues, and even time of day can also influence how much people eat.
- Demonstrates the interplay between physical signals and mental processes.
- Shows how environmental cues and habits shape eating patterns.
Example: Hormonal Influences
- Identify the hormones involved: Ghrelin increases hunger, while Leptin signals fullness.
- Discuss how these hormones interact in the brain: They send messages to the hypothalamus, which regulates eating.
- Analyze how external factors can alter eating habits: Social gatherings might encourage overeating despite feeling full.
Practice Problem:
A person continues to snack while watching TV even after feeling satisfied. Which factor could be affecting behavior?
Step-by-Step Solution
- Recognize that leptin levels might be sending “full” signals.
- Identify an external factor: The TV show or habit could override internal satiety cues.
- Conclude how behavior is motivated: The individual is driven by environmental or social cues rather than hunger.
B. Belongingness
Belongingness refers to the human need to form social connections. This drive for social interaction can shape decisions about food, gatherings, and personal preferences. For instance, family dinners often feature shared dishes that reinforce a sense of unity. Therefore, people might eat specific foods because it is customary within their community.
- Highlights the role of social ties in motivation.
- Explores how companionship and tradition influence decisions.
Example: Family Dinner Influences on Food Choices
- Discuss the significance of social interactions: Eating with loved ones can strengthen emotional bonds.
- Explore how gatherings shape food preferences: Cultural dishes and traditions create shared experiences.
- Analyze the emotional drive behind communal eating: Sharing meals fosters belonging and may motivate individuals to participate in group activities.
Practice Problem:
Two friends from different backgrounds share meals. How might belongingness prompt them to try each other’s traditional foods?
Step-by-Step Solution
- Recognize the social element: They respect each other’s background and want to connect.
- Consider how curiosity affects food choices: They are eager to taste new cuisine to strengthen their friendship.
- Relate to belongingness: By embracing each other’s cuisine, they reinforce social bonds.
