Introduction to Psychology
Psychology is a discipline that helps us understand the complexities of mental processes, experiences, and behavior in different contexts. It aims to:
- Understand the nature and role of psychology in understanding mind and behavior
- Trace the growth of the discipline
- Explore different fields of psychology and its relationship with other disciplines
- Appreciate the value of psychology in daily life
Quote: "The growth of the human mind is still high adventure, in many ways the highest adventure on earth." — Norman Cousins
What is Psychology?
Psychology is formally defined as a science that studies mental processes, experiences, and behavior in different contexts. It uses methods of biological and social sciences to obtain data systematically.
Key Components of Psychology
- Mental Processes: Activities like thinking, problem-solving, knowing, remembering, perceiving, and feeling. These are internal states of consciousness or awareness.
- Experiences: Subjective states that are embedded in our awareness or consciousness (e.g., pain, joy, meditation experiences).
- Behavior: Responses or reactions we make, which can be overt (observable) or covert (internal). Behavior is often studied as an association between stimulus (S) and response (R).
Psychology as a Discipline
Psychology seeks to understand and explain how the mind works and how mental processes result in behavior. It aims to minimize biases in explanations through scientific and objective analysis or by considering subjective experiences.
Two Parallel Streams of Psychology
- Natural Science Approach: Focuses on biological principles to explain behavior, assuming behavioral phenomena have discoverable causes.
- Social Science Approach: Focuses on how behavior can be explained through the interaction between individuals and their socio-cultural context.
Understanding Mind and Behavior
The mind cannot exist without the brain but is a separate entity. Neuroscience has shown relationships between mind and behavior:
- Positive visualization techniques can bring changes in bodily processes
- Mental imagery has been used to cure phobias
- Psychoneuroimmunology studies the mind's role in strengthening the immune system
Popular Notions vs. Scientific Psychology
Common sense explanations of behavior are often based on hindsight and explain little. Scientific psychology:
- Looks for predictable patterns of behavior
- Often contradicts common sense (e.g., Dweck's study showing that experiencing failure can be more beneficial than constant success)
- Systematically examines propositions based on data
Evolution of Psychology
1879: Wilhelm Wundt establishes first psychology laboratory in Leipzig, Germany (Structuralism)
1890: William James publishes Principles of Psychology (Functionalism)
1900: Sigmund Freud develops Psychoanalysis
1912: Gestalt psychology emerges in Germany
1916: First Psychology Department at Calcutta University established
1924: John B. Watson publishes 'Behaviorism'

Major Approaches in Psychology
- Structuralism: Analyzed the structure of the mind through introspection
- Functionalism: Focused on what the mind does and how behavior functions
- Gestalt Psychology: Emphasized that perceptual experience is more than the sum of components
- Behaviorism: Studied observable behavior rather than mental processes
- Psychoanalysis: Viewed behavior as manifestation of unconscious desires
- Humanistic Psychology: Emphasized free will and natural striving to grow
- Cognitive Psychology: Focuses on mental processes like thinking, memory, problem-solving
Development of Psychology in India
Psychology in India has developed through four phases:
- Pre-independence: Emphasis on experimental, psychoanalytic and psychological testing research
- Post-independence to 1960s: Expansion into different branches, attempting to link Western psychology to Indian context
- 1960s-1970s: Problem-oriented research focusing on Indian society's issues
- Late 1970s onward: Indigenization phase, developing culturally relevant frameworks based on traditional Indian psychology
Branches of Psychology
- Cognitive Psychology: Studies mental processes like attention, memory, reasoning
- Biological Psychology: Examines relationship between behavior and physical systems (brain, nervous system)
- Developmental Psychology: Studies physical, social and psychological changes across lifespan
- Social Psychology: Explores how people are affected by social environments
- Cross-cultural Psychology: Examines role of culture in behavior, thought and emotion
- Environmental Psychology: Studies interaction between physical factors and human behavior
- Health Psychology: Focuses on psychological factors in illness development and treatment
- Clinical Psychology: Deals with causes, treatment and prevention of psychological disorders
- Industrial/Organizational Psychology: Studies workplace behavior
- Educational Psychology: Studies how people learn and helps develop instructional methods
- Sports Psychology: Applies psychological principles to improve sports performance
Psychology and Other Disciplines
Psychology intersects with many other fields:
- Philosophy: Early psychological questions were philosophical
