• Structuralism

  • Wilhelm Wundt is considered the father of psychology
  • It focuses on understanding the basic elements or structures of consciousness
  • It uses introspection (self-examination of one's thoughts and feelings) as its primary method
  • It faced criticism for being too subjective

• Functionalism

  • William James is a key figure
  • It emphasizes the function and purpose of mental processes and behavior in adapting to the environment

  • Functionalism broadened the scope of psychology to include emotions and observable behaviors

• Psychoanalysis

  • Sigmund Freud developed this perspective

  • The theory has been criticized for being unscientific and overemphasizing sexuality

• Behaviorism

  • John B. Watson and B.F. Skinner are prominent figures
  • It focuses on observable behavior and the role of learning through conditioning
  • It rejects introspection and emphasizes objective measurement
  • Behaviorism has been successful in explaining simple forms of learning

• Gestalt Psychology

  • Max Wertheimer, Kurt Koffka, and Wolfgang Köhler are key figures
  • It emphasizes that the whole is different from the sum of its parts
  • It studies perception and problem-solving

  • It emphasizes the individual's potential for growth, self-actualization, and free will
  • It takes a positive view of human nature
  • It focuses on subjective experiences and personal values

• Cognitive Psychology

  • It studies mental processes like memory, thinking, and problem-solving
  • It uses experimental methods to infer mental processes
  • It is influenced by computer science and information processing models
  • Noam Chomsky's work on language influenced the cognitive revolution

• Biological Psychology

  • It examines the relationship between biological processes (brain, genes, hormones) and behavior
  • It uses techniques like brain imaging and genetic analysis
  • It is interdisciplinary, drawing from neuroscience, genetics, and physiology

Fields of Psychology

• Educational Psychology

  • It studies how people learn and the effectiveness of educational interventions
  • Educational psychologists conduct research and develop instructional strategies

• Developmental Psychology

  • It examines physical, cognitive, and social development across the lifespan
  • Developmental psychologists study children, adolescents, and adults

• Social Psychology

  • It studies how individuals' thoughts, feelings, and behaviors are influenced by others
  • Social psychologists study topics like attitude formation, persuasion, and group dynamics

• Cognitive Psychology

  • It investigates mental processes like memory, attention, and language
  • Cognitive psychologists conduct experiments and develop models of cognition

• Personality Psychology

  • It studies individual differences in personality traits and characteristics
  • Personality psychologists develop personality assessments and study personality development

• Industrial-Organizational Psychology

  • It applies psychological principles to the workplace
  • I/O psychologists work on employee selection, training, and organizational development

• Forensic Psychology

  • It applies psychological principles to the legal system
  • Forensic psychologists conduct evaluations, provide expert testimony, and consult with law enforcement

• Health Psychology

  • It examines the relationship between psychological factors and physical health
  • Health psychologists work on health promotion, disease prevention, and coping with illness

Methods of Psychology

• Introspection

  • It involves self-examination of one's own thoughts and feelings
  • Participants are trained to provide detailed reports of their experiences
  • It is subjective and difficult to replicate, making it less reliable
  • Structuralism primarily used introspection

• Observational Method

  • It involves observing and recording behavior in a natural or controlled setting
  • Naturalistic observation involves observing behavior in its natural context
  • Laboratory observation involves observing behavior in a controlled environment
  • It is useful for describing behavior but may not explain the underlying causes

• Case Study Method

  • It involves an in-depth investigation of a single individual or group
  • It can provide rich and detailed information about a particular phenomenon
  • Case studies are often used to study rare or unusual cases
  • Case studies may not be generalizable to the larger population
  • It is useful for generating hypotheses

• Interview Method

  • It involves asking participants questions to gather information
  • Structured interviews use a standardized set of questions
  • Unstructured interviews allow for more flexibility and follow-up questions
  • Interviews can provide detailed information about participants' experiences and opinions
  • Responses may be affected by social desirability bias, where participants provide answers they think are more socially acceptable

• Survey Method

  • It involves collecting data from a large sample of individuals through questionnaires or interviews
  • Surveys can be used to assess attitudes, beliefs, and behaviors
  • Surveys can be administered in person, by mail, online, or by telephone
  • The wording of survey questions can influence responses
  • It is important to obtain a representative sample to generalize the findings to the population

• Experimental Method

  • It involves manipulating one or more variables (independent variables) to observe the effect on another variable (dependent variable)
  • Participants are randomly assigned to different conditions (experimental and control groups)
  • It is used to establish cause-and-effect relationships
  • Confounding variables need to be controlled to avoid contaminating the results
  • Experiments can be conducted in a laboratory or field setting
  • Laboratory experiments offer more control but may lack ecological validity
  • Field experiments are conducted in real-world settings but may have less control

• Correlational Research

  • It examines the relationship between two or more variables
  • It does not involve manipulating variables
  • The correlation coefficient (r) measures the strength and direction of the relationship
  • Correlation does not equal causation
  • It can be used to make predictions
