What is Psychology?

  • Definition: The scientific study of the mind and behavior.

  • Core Questions:

    • What is creativity?

    • What are prejudice and discrimination?

    • What is consciousness?

  • Methodology: Psychology utilizes the scientific method to obtain knowledge.

The Scientific Method

  • Hypothesis: A tentative explanation for a phenomenon.

  • Theory: A broad explanation that is consistently supported by evidence over time.

  • Method: Researchers test hypotheses through observation and experimentation.

  • Publication: Results are shared so others can replicate or build on them.

Psychology as an Empirical Science

  • Empirical Method: Knowledge derived from observation and experimentation rather than solely logic or authority.

  • Measurable Data: Scientists focus on testing what is perceivable and measurable.

    • Example: While we cannot measure a bird's happiness, we can assess its brain state or inquire why it sings.

  • Fundamental Principle: Psychological science is grounded in measurable data.

The Challenge of the Mind

  • Scientific Dealings: Science traditionally handles matter and energy.

  • Abstract Nature of Thoughts: Thoughts and values do not fall into the categories of matter or energy, which challenges scientific interpretations of the mind.

  • Limitation: The scientific method, which is based on empiricism, requires measurable data.

Psychology's History and Scope

  • Disciplinary Development: Psychology emerged as a distinct academic discipline in the late 1800s, prior to which it was part of philosophy.

  • Nature of Psychology:

    • Behaviors have biological roots, categorizing psychology as a natural science.

    • The influence of social interactions on behavior qualifies psychology also as a social science.

Why Study Psychology?

  • Motivation: Many students pursue psychology to aid others or gain self-understanding.

  • Popularity: Psychology is a common major, constituting about 6% of all bachelor’s degrees in the U.S.

  • Interdisciplinary Relevance: Often a prerequisite for fields such as nursing and pre-med.

Wundt and Structuralism

  • Structuralism: Aims to identify the basic components of conscious experience.

  • Wundt's Perspective: Viewed psychology as the scientific study of conscious experience.

  • Methodology: Utilized introspection (internal perception) to investigate the human mind.

  • Expansion by Titchener: Structuralism was further developed by Wundt’s student Edward Titchener.

James and Functionalism

  • Functionalism: Concerned with how mental activities assist organisms in adapting to their environment.

  • Theoretical Influence: Inspired by Darwin’s theory of evolution through natural selection.

  • Focus of Functionalism: Interest in the functional operation of the entire mind, rather than its isolated parts.

  • Measuring Techniques: James employed objective measures beyond mere introspection.

Freud and Psychoanalytic Theory

  • Focus: Sigmund Freud emphasized the influence of the unconscious mind on behavior.

  • Core Belief: Many psychological issues arise from unconscious feelings and urges.

  • Psychoanalytic Theory: Centers on the unconscious and early childhood experiences.

  • Influential Techniques: Methods like dream analysis and the talking cure continue to hold sway today.

Gestalt Psychology

  • Key Figures: Influential German psychologists Wertheimer, Koffka, and Köhler introduced Gestalt psychology to the U.S.

  • Translation of Gestalt: Means "form" or "whole."

  • Fundamental Idea: The school asserts that the "whole is different from the sum of its parts."

  • Ongoing Relevance: Gestalt principles remain pertinent in research concerning sensation and perception.

Behaviorism: Pavlov and Watson

  • Behaviourism Definition: A paradigm that shifted the focus of psychology to observable behaviors rather than introspection of the mind.

  • Ivan Pavlov: Investigated classical conditioning, establishing learned reflex responses.

  • John B. Watson's Position: Argued that an objective analysis of the mind was unfeasible.

  • Research Methods: Behaviorism relied on animal models to study learned behaviors.

Behaviorism: B.F. Skinner

  • Focus of Study: B.F. Skinner explored how behavior is shaped by its consequences.

  • Core Concepts:

    • Reinforcement

    • Punishment

  • Innovative Research: Developed the Skinner box to investigate operant conditioning.

  • Significance: Behaviorism established psychology as a scientific discipline through objective methodologies.

Humanistic Psychology

  • Emergence: Developed in the early 20th century as a response to behavioral and psychoanalytic approaches.

  • Foundational Philosophy: Humanism highlights the intrinsic potential for goodness in all humans.

  • Maslow’s Hierarchy of Needs: Proposed a structure of needs culminating in self-actualization.

  • Carl Rogers' Contribution: Advanced client-centered therapy founded on unconditional positive regard, genuineness, and empathy.

The Cognitive Revolution

  • Revival Context: In the 1950s, the emergence of fields like computer science and neuroscience rekindled interest in mental processes.

  • Cognitive Revolution: A return to studying mental processes in psychology.

  • Ulric Neisser’s Publication: Authored the first textbook on cognitive psychology in 1967, marking a significant milestone.

  • Noam Chomsky’s Role: Emerged as a pivotal figure within this cognitive movement.

Women's Contributions to Psychology

  • Margaret Floy Washburn: The first woman to obtain a PhD in psychology in 1894.

  • Mary Whiton Calkins: Completed PhD requirements at Harvard but was denied the degree due to her gender.

  • Mary Cover Jones: Conducted pioneering research on unconditioning fear, which holds historical significance.

  • Feminist Psychology: This movement has worked to address biases within the field of psychology, leading to re-evaluations of various principles.

Diversity and Cross-Cultural Psychology

  • Francis Cecil Sumner: Acknowledged as the first African American to earn a PhD in psychology, awarded in 1920.

  • George I. Sanchez: Highlighted cultural and linguistic biases in intelligence assessments for Mexican American children.

  • Clark Research: Mamie Phipps Clark and Kenneth Clark’s findings on doll preference played a crucial role in the Brown v. Board of Education Supreme Court case.

  • Current Recognition: The field has evolved to acknowledge that studies conducted on WEIRD societies (Western, Educated, Industrialized, Rich, Democratic) are not universally applicable.

Professional Organizations

  • American Psychological Association (APA): The largest professional organization of psychologists globally, comprising 54 divisions.

  • Founding Figure: G. Stanley Hall was the inaugural president of the APA.

  • Association for Psychological Science (APS): Established to promote the scientific approach within psychology.

  • Ethnic-specific Groups: Includes organizations such as the National Latina/o Psychological Association (NLPA) and the Association of Black Psychologists (ABPsi).

Biopsychology and Evolutionary Psychology

  • Biopsychology Definition: Investigates how biological factors (e.g., the nervous system) influence behavior.

  • Evolutionary Psychology: Aims to understand the underlying biological causes of behavior informed by adaptation through natural selection.

    • Research Example: A 37-culture study by Buss (1989) revealed that women place higher value on earning potential, while men prioritize youth and attractiveness more than women do.

Sensation, Perception, and Cognition

  • Study Areas: The relationship between our sensory systems and psychological experiences.

  • Cognitive Psychology Focus: Centers on mental processes (cognitions) such as attention, problem-solving, language, and memory.

  • Historical Context: The Cognitive Revolution reinvigorated focus on the mind within scientific research.
