Psychology: Definitions, Goals, Branches & Approaches

TAKEAWAYS:

• Psychology is the scientific study of behavior and mental processes (thoughts, feelings, and actions).
• Its four main goals are to describe, explain, predict, and control behavior.
• Psychology has two major branches: basic (theory-driven) and applied (practical solutions).
• The six major approaches (biological, behavioral, cognitive, humanistic, psychodynamic, and sociocultural) offer different perspectives on human behavior.
• Key figures like Wilhelm Wundt, John B. Watson, and B.F. Skinner shaped psychology’s history.
• Psychology helps in everyday life (e.g., improving relationships, managing stress) and professions (e.g., counseling, education, marketing).

1. What is Psychology?

Psychology is the scientific study of behavior and mental processes. It helps us understand:

• Behavior: What people do (e.g., laughing, studying, helping others).
• Mental processes: What people experience (e.g., thinking, remembering, dreaming).

Why Study Psychology?

• Helps us understand ourselves and others.
• Improves communication, relationships, and decision-making.
• Used in education, business, healthcare, and law.

2. Goals of Psychology

Psychology has four main goals:

Example Trace: A student keeps forgetting their homework.

1. Describe: They leave their bag in the classroom.
2. Explain: They are distracted by phone notifications.
3. Predict: If they keep their phone away, they’ll remember better.
4. Control: They use a reminder app to track assignments.

3. Branches of Psychology

Psychology is divided into two main branches:

A. Basic (Theoretical) Psychology

• Focuses on understanding fundamental principles (e.g., how memory works).
• Conducts research to build knowledge.
• Example: Studying why people forget things over time.

B. Applied Psychology

• Uses psychology to solve real-world problems.
• Example areas:
  • Clinical Psychology: Treating mental health issues (e.g., anxiety, depression).
  • Educational Psychology: Improving teaching methods.
  • Industrial-Organizational Psychology: Boosting workplace productivity.
  • Social Psychology: Understanding group behavior (e.g., why people conform).

4. Approaches in Psychology

Psychologists use different approaches (or perspectives) to study behavior. Here are the six major ones:

1. Biological Approach

• Focuses on body and brain (genes, hormones, nervous system).
• Believes behavior is influenced by biology.
• Example: Studying how serotonin affects mood.

2. Behavioral Approach

• Focuses on observable behavior (what we can see).
• Believes behavior is learned from environment and experiences.
• Example: Rewarding a child for good grades to encourage study habits.

3. Cognitive Approach

• Studies mental processes (thinking, memory, problem-solving).
• Example: How people solve math problems differently.

4. Humanistic Approach

• Focuses on personal growth and free will.
• Believes people are naturally good and strive for self-improvement.
• Example: Therapy that helps people set and achieve personal goals.

5. Psychodynamic Approach

• Studies unconscious mind (hidden thoughts, childhood experiences).
• Example: Dreams revealing hidden fears or desires.

6. Sociocultural Approach

• Examines how society and culture shape behavior.
• Example: Why some cultures value individualism while others value group harmony.

6. Psychology in Everyday Life

Psychology helps in many areas:

Example: A teacher uses psychology to:

• Describe: Students are distracted in class.
• Explain: They are bored because lessons are too easy.
• Predict: If given challenging tasks, they’ll focus better.
• Control: Assigns group projects to increase engagement.

7. Careers in Psychology

Psychology graduates can work in many fields:

Exam Tip

The NEB exam tests definitions, goals, branches, and approaches. Focus on: ✅ Memorizing key terms (e.g., "Psychology is the scientific study of behavior and mental processes"). ✅ Differentiating branches (basic vs. applied) and approaches (biological vs. behavioral). ✅ Applying concepts (e.g., "How would a behavioral psychologist explain shyness?"). ✅ Short-answer questions often ask for examples (e.g., "Give one application of psychology in education"). ✅ Long-answer questions may ask you to compare two approaches (e.g., "How do the biological and cognitive approaches differ?").

Common Exam Questions:

1. Define psychology and state its four goals.
2. Differentiate between basic and applied psychology with examples.
3. Explain the behavioral approach and give one real-life application.
4. How has psychology contributed to education? Give two examples.
5. Compare the psychodynamic and humanistic approaches.

Practice Question (NEB Style): "Explain the biological approach to psychology. How does it differ from the behavioral approach? Give one example of each."

Answer: The biological approach studies how body structures (brain, genes, hormones) influence behavior. For example, low serotonin levels may cause depression.

The behavioral approach focuses on observable actions and how environment and learning shape behavior. For example, a child learns to fear dogs after being bitten.

Difference:

• Biological looks at internal causes (e.g., brain chemistry).
• Behavioral looks at external causes (e.g., past experiences).
