Psychology (Bachelor’s Degree) Important
Terminologies and Definition
Unit 1: Introduction to Psychology
This unit introduces the foundational concepts of psychology, its goals, branches, historical
foundations, debates, and ethical considerations. These topics form the bedrock for
understanding psychology as a science and discipline.
Topic 1: Definition and Goals of Psychology
1. Definition of Psychology
o Psychology: The scientific study of behavior (observable actions) and mental
processes (thoughts, feelings, and motives).
o Focuses on understanding individuals and groups by establishing general
principles and researching specific cases.
2. Goals of Psychology
o Describe: Observe and detail behaviors and mental processes accurately.
§ Example: Recording instances of aggression in a classroom setting.
o Explain: Provide reasons or causes for behavior.
§ Example: Explaining aggression as a response to frustration.
o Predict: Anticipate future behaviors based on patterns.
§ Example: Predicting that stress will decrease performance under
pressure.
o Control: Influence or modify behavior for positive outcomes.
§ Example: Implementing stress management techniques to reduce
anxiety.
3. Key Terminologies
o Behavior: Any observable action made by a living person or animal.
o Mental Processes: Internal experiences such as thoughts, feelings, and motives.
o Empirical Evidence: Information obtained through observation and
experimentation.
Important Note: Psychology emphasizes using the scientific method to ensure objectivity and
reliability.
Topic 2: Branches of Psychology
Psychology is diverse, encompassing various subfields that address specific questions and
applications.
1. Clinical Psychology
o Focuses on diagnosing and treating mental, emotional, and behavioral disorders.
o Example: Treating depression through cognitive-behavioral therapy (CBT).
, 2. Cognitive Psychology
o Studies mental processes like perception, memory, and problem-solving.
o Example: Researching how people remember and forget information.
3. Developmental Psychology
o Examines psychological growth throughout a person’s lifespan.
o Example: Studying how language develops in children.
4. Social Psychology
o Explores how individuals are influenced by their social environments.
o Example: Investigating group behavior and conformity.
5. Industrial-Organizational Psychology
o Applies psychological principles to workplace settings.
o Example: Improving employee productivity through motivational strategies.
Key Terminologies
• Therapy: A process designed to improve psychological functioning and promote
personal growth.
• Cognition: All mental activities associated with thinking, knowing, remembering, and
communicating.
• Conformity: Adjusting behaviors or attitudes to align with a group norm.
Important Note: Each branch overlaps with others, reflecting the interdisciplinary nature of
psychology.
Topic 3: Historical Foundations of Psychology
1. Major Figures in Psychology
o Wilhelm Wundt: Known as the "father of psychology," he established the first
psychology laboratory in 1879.
o William James: Focused on functionalism, studying the purpose of behavior and
mental processes.
o Sigmund Freud: Developed psychoanalysis, emphasizing the unconscious
mind's role in behavior.
2. Movements in Psychology
o Structuralism: Early school of thought led by Wundt and Titchener that used
introspection to explore the structure of the mind.
o Functionalism: Focused on how mental processes enable adaptation, survival,
and flourishing.
o Behaviorism: Championed by John B. Watson and B.F. Skinner, this
perspective emphasizes observable behavior over mental processes.
o Humanism: Led by Carl Rogers and Abraham Maslow, it emphasizes personal
growth and self-actualization.
3. Key Terminologies
o Introspection: Examination of one’s own conscious thoughts and feelings.
o Unconscious Mind: Part of the mind housing desires, memories, and impulses
outside of conscious awareness.
o Self-Actualization: The realization of one’s potential and abilities.
, Important Note: Psychology has evolved from philosophy to a rigorous science, adapting its
methods and focus areas over time.
Topic 4: Nature vs. Nurture Debate
1. Definition
o The debate centers on whether human behavior is determined by genetics
(nature) or environment (nurture).
o Nature: Innate qualities inherited from parents (e.g., intelligence, temperament).
o Nurture: Influences of upbringing, culture, and personal experiences.
2. Examples
o Twin studies show similarities in intelligence despite different environments,
highlighting the role of nature.
o Language acquisition in children depends on environmental exposure,
showcasing nurture’s impact.
3. Key Terminologies
o Heredity: The transmission of traits from parents to offspring.
o Environment: External factors influencing development, such as social settings
and education.
o Epigenetics: Study of how environmental factors can influence gene expression
without altering DNA.
Important Note: Most psychologists adopt an interactionist approach, recognizing that nature
and nurture work together.
Topic 5: Ethics in Psychology
1. Definition
o Ethics are principles that guide psychologists in conducting research and
practicing responsibly.
o Governed by bodies like the American Psychological Association (APA).
2. Core Ethical Principles
o Informed Consent: Participants must know the study's purpose and risks before
agreeing.
o Confidentiality: Protecting participants’ personal information.
o Debriefing: Explaining the study’s purpose after completion, especially if
deception was involved.
3. Examples of Ethical Practices
o Milgram’s obedience study faced criticism for causing distress, leading to stricter
ethical standards.
o Using anonymous surveys to maintain confidentiality.
4. Key Terminologies
o Deception: Misleading participants about the true purpose of the study
(acceptable only when justified).
o Beneficence: Ensuring the well-being of participants by minimizing harm.
o Autonomy: Respecting participants’ rights to make their own decisions.
