Psychology's Foundations, History, and Professional Subfields

Foundations of Psychological Perspectives and Research Questions

Psychology’s Scope: Psychologists investigate a diverse range of topics, extending far beyond the common depictions in media like analyzing personality or examining crime scenes. Research questions include:
- Biological Inheritance: Exploring how much of a person's personality is inherited from parents versus shaped by home and community environments.
- Human Diversity and Similarity: Investigating how people of different cultures, races, genders, and sexual orientations are alike or differ within the human family.
- Consciousness and Dreams: Why we experience nightmares and the physiological or neurological reasons for dreaming.
- Child Development: Why a $6$ -month-old child finds peekaboo delightful, and what infants actually perceive when an object disappears behind a door.
- Success and Intelligence: Examining if intelligence is innate and whether it explains wealth, creativity, or social sensitivity.
- Mental Health Boundaries: Defining the line between normal mood swings and psychological disorders necessitating professional help.
- Modern Technology Impacts: Assessing how the Internet, video games, and social media influence human thinking and relational patterns.
Universal Human Nature: While cultural and gender diversity exists (such as varies in smiling frequency), a naturally happy smile is a universal expression with the same meaning worldwide.

The Evolution of Prescientific Psychology

Early Historical Roots: The core questions of psychology trace back through global history:
- India: Buddha explored how sensations and perceptions combine to form ideas.
- China: Confucius emphasized the power of the educated mind and ideas.
- Ancient Israel: Hebrew scholars linked emotion and mind to the body, suggesting people think with their hearts and feel with their bowels.
Ancient Greece:
- Socrates ( $469-399$ b.c.e.) and Plato ( $428-348$ b.c.e.): Argued that the mind is separable from the body and continues after death. They maintained that knowledge is innate—born within us.
- Aristotle ( $384-322$ b.c.e.): Unlike his teacher Plato, Aristotle used careful observation and data. He argued that knowledge is not preexisting but grows from experience stored in memory.
The Enlightenment and Modern Science ( $1600$ s):
- René Descartes ( $1595-1650$ ): Agreed with Socrates and Plato on innate ideas and mind-body dualism. He proposed that "animal spirits" flowed from the brain through hollow nerves to the muscles to cause movement, and that experiences opened pores in the brain to form memories.
- Francis Bacon ( $1561-1626$ ): A founder of modern science who focused on the mind's tendency to perceive patterns in random events. He wrote in $Novum\,Organuum\,(1620)$ that the human understanding easily supposes more order than is actually present.
- John Locke ( $1632-1704$ ): In $An\,Essay\,Concerning\,Human\,Understanding$ , he argued the mind is a $tabula\,rasa$ (blank slate) at birth. This contributed to the concept of Empiricism, the view that knowledge originates in experience and science should rely on observation and experimentation.

The Birth and Growth of Modern Psychological Science

Wilhelm Wundt and the First Laboratory: Psychology as an experimental science was born in December $1879$ at the University of Leipzig, Germany. Wundt and his students sought to measure "atoms of the mind," the fastest and simplest mental processes.
- Reaction Time Experiment: Participants were asked to press a telegraph key when a ball hit a platform. Reaction time was approximately $\frac{1}{10}$ of a second for hearing the sound, but $\frac{2}{10}$ of a second for conscious awareness of the sound.
Expansion to the United States: G. Stanley Hall, a student of Wundt, established the first formal U.S. psychology laboratory at Johns Hopkins University in $1883$ .

Early Schools of Thought: Structuralism and Functionalism

Structuralism: Introduced by Edward Bradford Titchener at Cornell University in $1892$ . Aimed to discover the structural elements of the mind using Introspection (self-reflective looking inward).
- Subjects reported immediate sensations, images, and feelings while smelling scents or tasting substances.
- Structuralism waned because introspection proved unreliable, required high verbal ability, and people's self-reports were often erroneous.
Functionalism: Promoted by William James and influenced by Charles Darwin. James focused on the evolved functions of our thoughts and feelings.
- James argued that consciousness serves a function: it allows us to consider the past, adjust to the present, and plan the future. As a functionalist, he explored emotions, memories, willpower, and habits.

Pioneering Women in the History of Psychology

Mary Whiton Calkins: Admitted to William James's graduate seminar at Harvard in $1890$ against university objections. Though she finished all requirements and outscored male students, Harvard offered her a degree from Radcliffe College (the undergraduate school for women), which she refused. She became a memory researcher and the first female president of the American Psychological Association (APA) in $1905$ .
Margaret Floy Washburn: The first woman to actually receive a psychology Ph.D. She wrote $The\,Animal\,Mind\,(1908)$ and became the second female APA president in $1921$ . She was initially barred from joininig the organization of experimental psychologists due to her gender.
Modern Shifts: From $1996$ to $2013$ , women earned approximately $\frac{2}{3}$ or more of new U.S. psychology Ph.D.s and held $9$ of the $18$ elected presidencies of the Association for Psychological Science (APS).

Historical Shifts in the Definition of Psychology

Pre- $1920$ s: Defined as "the science of mental life."
$1920$ s to $1960$ s (Behaviorism): John B. Watson and B. F. Skinner dismissed introspection. They redefined psychology as "the scientific study of observable behavior," arguing that mental processes (feelings, thoughts) cannot be scientifically observed, but behavior can.
Freudian Psychology: Emphasized how unconscious thought processes and childhood emotional responses affect behavior. This evolved into the modern Psychodynamic Approach.
$1960$ s (Humanism and the Cognitive Revolution):
- Humanistic Psychology: Led by Carl Rogers and Abraham Maslow. Rejected behaviorism and Freudianism as too limiting. Focused on how environmental influences nurture or limit growth potential and the importance of having needs for love and acceptance met.
- The Cognitive Revolution: Led the field back to its interest in mental processes. Cognitive psychology focuses on how we perceive, process, and remember information. Cognitive neuroscience studies the brain activity underlying these mental activities.
Modern Definition: Psychology is the science of behavior and mental processes.
- Behavior: Any action an organism does that can be observed and recorded (e.g., sweating, smiling, talking).
- Mental Processes: Internal, subjective experiences inferred from behavior (e.g., sensations, beliefs, feelings).

Psychology’s Big Issues

Nature-Nurture Issue: The longstanding controversy over the relative contributions of genes (nature) and experience (nurture).
- Plato and Descartes argued some ideas are innate; Aristotle and Locke argued they come from the senses/experience.
- Charles Darwin ( $1859$ ): In $On\,the\,Origin\,of\,Species$ , he proposed Natural Selection—nature selects traits that best enable survival and reproduction. Today, the field views traits as arising from the interaction of nature and nurture: "Nurture works on what nature endows."
Levels of Analysis: Complex systems require different, complementary outlooks.
- The Biopsychosocial Approach: Integrates Biological influences (genetic predispositions, hormonal influences), Psychological influences (learned expectations, emotional responses), and Social-cultural influences (presence of others, cultural/peer expectations).

Contemporary Psychological Perspectives

Behavioral: Focuses on how we learn observable responses and which external stimuli trigger aggression or fear.
Biological: Investigates how the body and brain enable emotions and memories, and how genes combine with the environment to influence individual differences.
Cognitive: Studies how we encode, process, store, and retrieve information.
Evolutionary: Examines how natural selection has promoted the survival of specific genes and behavior tendencies.
Humanistic: Investigates how we meet needs for love and achieves self-fulfillment.
Psychodynamic: Views behavior as springing from unconscious drives and childhood conflicts.
Social-Cultural: Explores how thinking and behavior vary across situations and cultural contexts.

Psychology’s Subfields and Research Areas

Psychometrics: The study of the measurement of human abilities, attitudes, and traits.
Basic Research Subfields:
- Biological Psychologists: Study links between brain and mind.
- Developmental Psychologists: Study changing abilities from "womb to tomb."
- Cognitive Psychologists: Experiment with perception, language, and problem-solving.
- Educational Psychologists: Study influences on teaching and learning.
- Personality Psychologists: Investigate persistent traits.
- Social Psychologists: Explore how we view and affect one another.
Applied Research Subfields:
- Industrial-Organizational (I/O): Apply psychological concepts to optimize behavior in workplaces or train employees.
- Human Factors: Subfield of I/O focusing on interactions between people, machines, and physical environments.
- Forensic Psychologists: Apply principles to legal issues, jury selection, and criminal investigations.
- Health Psychologists: Focus on promoting health and preventing disease (e.g., programs to stop smoking or lose weight).
- Neuropsychologists: Assess and treat central nervous system disorders (e.g., Alzheimer's, stroke, ADHD).
- Rehabilitation Psychologists: Work with those who have lost optimal functioning after an illness or accident.
- School Psychologists: Diagnose and treat cognitive or social problems in children within educational settings.
- Sport Psychologists: Study psychological factors influencing sports participation.

The Helping Professions

Counseling Psychologists: Assist people with problems in living (school, work, marriage) to achieve greater well-being.
Clinical Psychologists: Assess and treat mental, emotional, and behavior disorders through psychotherapy.
Psychiatrists: Medical doctors licensed to prescribe medication and provide medical treatments in addition to psychotherapy.
Community Psychologists: Focus on how people interact with social environments and institutions to promote psychological health via preventive measures.
Positive Psychology: Scientifically explores human flourishing, positive character traits, and strengths that help communities thrive (Martin Seligman).
Historical Reformers: Dorothea Dix and Philippe Pinel led efforts for the humane treatment of the insane in cages and psychological facilities.

Applied Study Principles and the Science of Retention

The Testing Effect: Memory research (Roediger and Karpicke, $2006$ ) shows that repeated self-testing and retrieval is more effective than rereading.
SQ3R Study Method:
1. Survey: Scan headings and organization.
2. Question: Attempt to answer learning objectives before reading.
3. Read: Search for answers and read critically/actively.
4. Retrieve: Test yourself on main ideas immediately after reading a section.
5. Review: Read over notes and summarize concepts from memory.
Additional Study Tips:
- Distribute Study Time: Spaced practice ( $1$ hour/day for $6$ days) is superior to massed practice (a $7$ -hour blitz).
- Process Information Actively: Take notes in your own words; listen for main ideas in class.
- Overlearn: Continue studying and testing even after you feel you know the material to prevent overconfidence.
- Smart Test-Taking: Answer multiple-choice questions as if they were fill-in-the-blank before looking at choices. Tackle essay (FRQ) questions by outlining points first.
