History of Psychology Overview

Ancient Roots:
- Philosophy and psychology intertwined; early thinkers like Socrates, Plato, and Aristotle explored human behavior and thought.
Structuralism:
- Founded by Wilhelm Wundt in the late 19th century.
- Focused on breaking down mental processes into basic components (introspection).
Functionalism:
- Developed by William James as a response to structuralism.
- Emphasized the purpose of mental processes in adapting to environments.
Psychoanalysis:
- Founded by Sigmund Freud in the early 20th century.
- Focused on unconscious processes and childhood experiences impacting behavior.
Behaviorism:
- Promoted by John B. Watson and B.F. Skinner.
- Emphasized observable behavior and dismisses mental processes as subjects of study.
Humanistic Psychology:
- Emerged in the mid-20th century with figures like Carl Rogers and Abraham Maslow.
- Focused on individual potential and self-actualization.
Cognitive Revolution:
- Started in the 1950s, focusing on mental processes like thinking, memory, and problem-solving.
Contemporary Psychology:
- Integrates various approaches and emphasizes diversity, culture, and biology in understanding behavior.

Biological Perspective:
- Examines the influence of genetics, brain structures, and neurochemistry on behavior.
Cognitive Perspective:
- Focuses on mental processes including perception, memory, and decision-making.
Behavioral Perspective:
- Studies how behavior is learned and reinforced through interactions with the environment.
Psychodynamic Perspective:
- Explores how unconscious drives and conflicts shape behavior, rooted in Freud's theories.
Humanistic Perspective:
- Emphasizes personal growth, self-fulfillment, and the subjective experience of individuals.
Evolutionary Perspective:
- Examines behavior through the lens of natural selection and adaptation over time.
Sociocultural Perspective:
- Considers how culture, society, and interpersonal relationships influence behavior.

Experimental Method:
- Involves manipulating one variable (independent variable) to observe its effect on another (dependent variable).
- Allows for establishing cause-and-effect relationships.
Correlational Method:
- Examines the relationship between two variables without manipulation.
- Correlation coefficients indicate the strength and direction of the relationship (positive, negative).
Surveys and Questionnaires:
- Gather data from a large group of people through self-reported responses.
- Useful for accessing attitudes, beliefs, and behaviors.
Case Studies:
- In-depth analysis of a single individual or group.
- Provides detailed qualitative data but lacks generalizability.
Observational Method:
- Involves observing subjects in a natural or controlled environment.
- Can be structured (specific behaviors) or unstructured (general observation).
Longitudinal and Cross-Sectional Studies:
- Longitudinal: Follows the same subjects over a prolonged period.
- Cross-Sectional: Compares different groups at one point in time.
Ethical Considerations:
- Informed consent, confidentiality, and minimizing harm are crucial in psychological research.

Ancient psychology intertwined with philosophy; significant contributions from thinkers like Socrates, Plato, and Aristotle who analyzed human behavior and cognition.
Structuralism, founded by Wilhelm Wundt, aimed to dissect mental processes into their fundamental elements through introspection in the late 19th century.
Functionalism arose from William James as a counter to structuralism, focusing on the adaptive significance of mental processes.
Sigmund Freud established psychoanalysis in the early 20th century, emphasizing the role of unconscious drives and childhood experiences in shaping behavior.
Behaviorism, led by John B. Watson and B.F. Skinner, shifted the focus to observable behaviors and rejected the study of internal mental processes.
Humanistic psychology emerged in the mid-20th century, forefronted by Carl Rogers and Abraham Maslow, concentrating on individual potential and self-actualization.
The cognitive revolution of the 1950s redirected attention to processes such as thinking, memory, and problem-solving.
Contemporary psychology synthesizes various methods and highlights the importance of diversity, culture, and biological influences on behavior.

The biological perspective looks at genetic, neurophysiological, and biochemical influences on behavior.
Cognitive perspective emphasizes the analysis of mental functions including perception, memory, and decision-making processes.
Behavioral perspective investigates the acquisition and reinforcement of behaviors through environmental interactions.
Psychodynamic perspective delves into unconscious conflicts and drives, built on Freud's foundational theories.
Humanistic perspective spotlights personal growth, self-fulfillment, and individual subjective experiences.
Evolutionary perspective interprets behaviors through the lens of natural selection and evolutionary adaptations.
Sociocultural perspective evaluates how cultural contexts, societal structures, and interpersonal relationships shape behaviors.

Experimental method manipulates independent variables to establish causal relationships, allowing for definitive conclusions about effects on dependent variables.
Correlational method assesses relationships between variables, with correlation coefficients indicating direction (positive or negative) and strength of the association.
Surveys and questionnaires capture self-reported attitudes, beliefs, and behaviors from a diverse population, providing broad insights.
Case studies offer detailed qualitative analysis of individuals or groups, though generalization is limited due to the focus on specific cases.
Observational methods involve monitoring subjects in either natural or controlled settings, either systematically (specific behaviors) or organically (unstructured observation).
Longitudinal studies track the same subjects over time, while cross-sectional studies compare different demographics at a single point in time.
Ethical considerations in research prioritize informed consent, confidentiality, and the minimization of harm to participants.
