Foundations and Perspectives in Psychology: Past and Present

Psychology’s Past and Present

Historical Origins of Psychology

Psychology originated as a branch of philosophy, with ancient Greek thinkers contemplating the nature of the mind. It became a formal scientific discipline in the late 19th century.

• Early Roots: Philosophers such as Plato and Aristotle speculated about the mind, consciousness, and behavior.

• Formalization: Psychology emerged as a distinct scientific field in the late 1800s.

• Wilhelm Wundt: Established the first psychology laboratory in 1879, marking the official beginning of experimental psychology. He focused on identifying the basic building blocks of the mind, a perspective known as structuralism.

Theoretical Perspectives in Psychology

Overview of Major Schools of Thought

Modern psychology has been shaped by several key theoretical perspectives, each offering different explanations for human behavior and mental processes.

• Structuralism

• Functionalism

• Behaviorism

• Cognitivism

• Psychodynamic

Structuralism

Structuralism was the first major school of thought in psychology, aiming to understand the structure and characteristics of the mind through introspection.

• Key Figures: Wilhelm Wundt and E.B. Titchener

• Method: Systematic introspection—careful observation and reporting of one's own conscious experiences.

• Goal: Identify the basic elements (sensations, feelings, images) that make up conscious experience, similar to how chemists identify elements in the periodic table.

• Example: Participants might be asked to describe their sensations when viewing a stimulus, such as a light or sound.

Functionalism

Functionalism focused on the purpose of mental processes and behavior, emphasizing how they help individuals adapt to their environments.

• Key Figure: William James (first American psychologist)

• Focus: What the mind does and how behavior functions in the real world.

• Influence: Heavily influenced by Charles Darwin’s theory of natural selection, suggesting that psychological traits have adaptive functions.

• Example: Studying how memory aids survival by helping individuals remember dangerous situations.

Psychodynamic Perspective

The psychodynamic approach, founded by Sigmund Freud, emphasizes the influence of the unconscious mind and early childhood experiences on behavior.

• Key Figure: Sigmund Freud

• Focus: Unconscious motives, conflicts, and past experiences, especially from childhood.

• Methods: Dream analysis, free association, and the study of hysteria and neurosis.

• Example: Exploring how repressed childhood trauma can manifest as adult anxiety.

Behaviorism

Behaviorism argues that psychology should focus on observable behavior rather than internal mental states, as only observable phenomena can be scientifically studied.

• Key Figure: John B. Watson (father of behaviorism)

• Principle: Objective analysis of the mind is impossible; instead, study observable behavior and how it can be controlled.

• Applications: Behavioral therapy and cognitive-behavioral therapy (CBT) are based on these principles.

• Example: Conditioning a child to fear a white rat by pairing it with a loud noise (Little Albert experiment).

B.F. Skinner and Operant Conditioning

• Key Figure: B.F. Skinner

• Focus: How behavior is shaped by its consequences (reinforcement and punishment).

• Operant Conditioning: Learning process in which the likelihood of a behavior is increased or decreased by the consequences that follow it.

• Example: A rat presses a lever to receive food (positive reinforcement), or to avoid a shock (negative reinforcement).

• Equation:

$\text{Behavior} \xrightarrow{\text{Consequence}} \text{Change in Likelihood of Behavior}$

Cognitivism

Cognitivism focuses on the mental processes underlying behavior, such as perception, memory, and problem-solving. It emphasizes the importance of how people interpret and mentally represent the world.

• Key Figures: Jean Piaget and Ulric Neisser

• Focus: Internal mental processes and how they influence behavior.

• Principle: Behavior is not just a response to stimuli, but is shaped by how individuals interpret and process information.

• Example: Studying how children develop logical thinking and understanding of the world (Piaget’s stages of cognitive development).

Women in Psychology

Barriers and Contributions

Women have historically faced significant barriers in psychology due to social prejudice and exclusion from academic programs. Despite this, many have made important contributions to the field.

• Barriers: Exclusion from graduate programs, underrepresentation at the highest academic ranks (only 28% of faculty at the highest rank, though 44% of faculty overall).

• Pay Gap: Male professors earn on average $5,000 more per year than female counterparts in Canada.

• Notable Figures: Esther Greenglass (only woman in her graduate program at U of T), Margaret Floy Washburn (first woman to receive a PhD in psychology).

How Do We Know What We Know?

Sources of Knowledge

Psychological knowledge can be derived from several sources, each with its strengths and limitations.

• Authority: Accepting information from experts or respected sources.

• Reason: Using logical thinking and deduction.

• Observation: Gathering empirical evidence through the senses or scientific instruments.

Common Sense and Intuition

People often rely on common sense or intuition, but these can be misleading or contradictory.

• Examples of contradictory sayings:

  • "Birds of a feather flock together" vs. "Opposites attract"

  • "Absence makes the heart grow fonder" vs. "Out of sight, out of mind"

  • "You can’t teach an old dog new tricks" vs. "Never too old to learn"

The Bystander Effect and Social Psychology

Case Study: Kitty Genovese

The bystander effect is a social psychological phenomenon where individuals are less likely to help a victim when other people are present. The infamous case of Kitty Genovese, where 37 witnesses reportedly did not call the police during her murder, illustrates this effect.

• Key Concept: "There is safety in numbers" can be misleading; sometimes, the presence of others leads to inaction.

• Scientific Study: Psychologists study such phenomena to understand the factors that influence helping behavior.
