Foundations of Psychology: Roots, Old Schools, and Modern Extensions
Roots of psychology: philosophy and physiology
Psychology has two roots: philosophy and physiology.
Philosophy seeks to understand what we do and why we do it (the why behind behavior and mental processes).
Physiology studies the biological processes that contribute to brain function and behavior, including internal bodily processes and the nervous system.
In practice, psychology focuses mainly on the brain and behavior, but also discusses the nervous system as a whole.
Early examples in physiology mentioned: Hippocrates as a physiologist who studied brain-related issues.
The two roots together build the foundation for understanding human behavior scientifically.
Definition of psychology
Psychology is the study of behavior and mental processes. This definition has been reinforced as a core concept (appears repeatedly in lectures and exam-style questions).
Psychology is a science; it uses evidence-based methods to study mental processes and behavior.
Old-school psychology: schools and perspectives
Structuralism (early school): seeking to understand the structure of the mind and its basic thoughts/experiences.
Founders: Wilhelm Wundt (often credited as the father of psychology) and his student Edward Titchener.
Method: introspection to catalog basic mental processes (the “basic parts” of experience).
Key idea: map the structure of mental processes like a periodic table of the mind; data collection aimed at isolating components.
Limitation: introspection was subjective; even when efforts were made to be objective, results varied across individuals.
Functionalism: focus on the function and purpose of mental processes, rather than their structure.
Founder: William James (often called the father of American psychology).
Key idea: study how mental processes help us adapt, survive, and flourish; what is the purpose of these processes?
Contrast with structuralism: not about “parts” but about “why” and “how” mental processes are used.
Psychoanalysis (Freud): emphasis on unconscious processes and internal motives driving behavior.
Founder: Sigmund Freud (neurologist turned theorist).
Goals: understand unconscious motives and conflicts; develop therapies to address neurotic symptoms.
Notes on modern practice: psychoanalysis remains a controversial, less-dominant approach; many contemporary therapies draw on psychoanalytic ideas (psychodynamic) but with variations.
Ethical and access concerns discussed: psychoanalysis often requires frequent sessions and substantial cost; critiques about accessibility and cultural generalizability.
Behaviorism: emphasis on observable behavior and environmental determinants; the “black box” of the mind is not the focus.
Key figures: John B. Watson and B. F. Skinner.
Core idea: behavior can be studied objectively through observable stimuli and responses; internal mental states are not necessary for explanation.
Relevance: laid the groundwork for learning theories and experimental methods in psychology.
Humanism (third force): emphasis on human potential, growth, and positive aspects of psychology.
Key figures: Carl Rogers and Abraham Maslow.
Core idea: humans have an inherent drive toward growth and self-actualization; focus on positive aspects of human nature and therapeutic approaches that foster growth.
Rise of positive psychology: later development emphasizing well-being, strengths, and thriving (see Martin Seligman).
Summary: these schools represent early attempts to organize how we study mind and behavior, each offering distinct questions, methods, and implications for therapy and research.
Founders and key figures
Wilhelm Wundt: often regarded as the father of psychology; structuralism association.
Edward Titchener: student of Wundt; helped establish structuralism.
William James: father of American psychology; functionalist perspective.
Sigmund Freud: founder of psychoanalysis; unconscious motives and early childhood experiences.
John B. Watson: behaviorism pioneer; emphasis on observable behavior.
B. F. Skinner: behaviorist; reinforcement and conditioning emphasis.
Carl Rogers: humanist; person-centered therapy and emphasis on growth.
Abraham Maslow: humanist; hierarchy of needs and self-actualization.
Martin Seligman: key figure in positive psychology (later developments); focus on strengths, happiness, and thriving.
Note: some names in the transcript are misspelled (e.g., Wilhelm Bunt, Edner Titchener). Corrected conventions are used here for clarity.
The move from old to new psychology: integration and expansion
New psychology areas mentioned or implied: cognitive psychology, evolutionary psychology, multicultural psychology, neuroscience.
Neuroscience as a bridge to biology: emphasizes brain function and the nervous system; investigates how brain activity relates to behavior.
The idea that psychology continuously evolves by integrating biology, environment, culture, and cognition.
Neuropsychology and neuroscience: brain, imaging, and interpretation
Neuroscience as an offshoot of functionalism and as a key modern focus.
Brain and nervous system as the underlying hardware for behavior; the brain directs the body via the nervous system.
Imaging and monitoring technologies mentioned:
Positron Emission Tomography (PET): metabolic imaging to observe brain activity.
Functional Magnetic Resonance Imaging (fMRI): measures brain activity by detecting changes associated with blood flow; high spatial resolution.
Other imaging modalities exist but were not the focus of this lecture.
Important caveats:
Imaging shows correlations between brain activity and behavior, not causation.
Correlation does not prove causation; one must be careful about inferring direct causal links from imaging data alone.
Distinction between correlation and causality will be revisited in the course when discussing research design.
Conceptual takeaway: neuroscience provides a biological basis for understanding mental processes, but it must be integrated with behavioral and psychological data.
Multiculturalism and the APA: culture in psychology
Modern psychology increasingly recognizes culture and diversity as central to understanding behavior.
The American Psychological Association (APA) has divisions that explicitly address multiculturalism and diversity in research and practice.
Critique noted in the transcript: culture has not always been deeply integrated into classic theories (e.g., Freud’s theory, many early models lacked attention to cultural variation).
Practical implication: researchers should consider culture in study design, interpretation, and application; otherwise, findings may not generalize across diverse populations.
The course will address diversity and social psychology more explicitly as topics are introduced.
The biopsychosocial model: an integrative framework
The biopsychosocial model: a comprehensive approach to understanding behavior and mental health.
Biological level: genetics, brain structure and function, neurotransmitters, brain injuries, medications.
Psychological level: emotions, temperament, coping strategies, cognitive processes.
Social level: SES, culture, relationships, environment, social support.
How the model works:
Biological factors can influence psychological processes and behavior, and vice versa.
Psychological states can influence biological processes (e.g., stress affecting hormones) and social interactions.
Social context can shape biological responses (e.g., stressors) and psychological outcomes.
Rationale: this model is often used in psychological disorder research and practice to capture the complexity of human behavior.
Positive psychology: growth, strengths, and well-being
Positive psychology focuses on what enables individuals and communities to thrive.
Key figure: Martin Seligman (often cited as the father of positive psychology).
Though the transcript contains a humorous misname, Seligman is the widely recognized proponent.
Core concepts within positive psychology:
Happiness and well-being as measurable constructs, not merely the absence of illness.
Flow: states of optimal experience and deep engagement in activities (example given: axe throwing makes one feel “in the flow” and perform with precision).
Strengths, optimism, forgiveness, and grit (persistence in the face of challenges).
Context: positive psychology emerged as a response to a field heavily focused on disorders and problems; it emphasizes thriving and resilience.
Important caveat: positive psychology builds on humanism and integrates with the biopsychosocial model to promote flourishing.
Key concepts and distinctions to remember for exams
Core definitions:
Psychology: the study of behavior and mental processes; a science.
Foundational roots: philosophy (why we do what we do) and physiology (biological underpinnings of behavior).
Structuralism vs. functionalism:
Structuralism seeks the mind’s components via introspection.
Functionalism asks what mental processes are for and how they help adaptation.
Psychoanalysis vs. behaviorism vs. humanism:
Psychoanalysis focuses on unconscious processes and internal conflicts.
Behaviorism emphasizes observable behavior and learning from the environment.
Humanism centers on growth, self-actualization, and positive aspects of human nature.
New psychology domains: cognitive, evolutionary, multicultural, neuroscience; integration across domains.
The biopsychosocial model: a holistic framework combining biology, psychology, and social factors.
Neuroscience methods: PET and fMRI as tools for observing brain activity; correlations vs. causation cautions.
Multiculturalism in research: culture influences are critical for generalizability and ethical practice; represented in APA divisions and modern research.
Positive psychology constructs: happiness, flow, optimism, forgiveness, grit; emphasis on thriving rather than only pathology.

Course logistics and study tips mentioned in the transcript
Access to course materials and links: links may be shared in chat or Achieve; some materials may be posted later depending on availability.
Screenshots of slides are allowed; however, some slides may include questions to test you later, so the instructor may withhold certain content until later in the course.
Assignments and due dates: assignments may be posted on Achieve (some content may also appear on Canvas); check the syllabus schedule for deadlines (e.g., the first assignment mentioned was due on the 15th in the transcript).
If you don’t see an assignment link, contact the teaching assistant or wait for the instructor to post it; there may be delays due to illness.
When reading and studying, emphasis should be on understanding concepts and their connections across theories, rather than memorizing isolated names.
Metaphors and concrete examples used in class notes
Periodic-table-like metaphor for identifying mental processes in structuralism: “the basic parts” of mental processes.
Introspection as a method: listening for a sound and noting when it’s heard; illustrates the subjective nature and limitations of introspection.
Flow example: axe throwing as a real-world activity illustrating being in a flow state, where performance is consistently high.
Clearing up confusion with names: the speaker notes common misnamings (e.g., Martin Seligman vs. Segelman) to help remember key figures correctly.
Ethical, philosophical, and practical implications discussed
Psychoanalysis as a therapy with accessibility and socio-economic considerations: high cost, long-term commitment, and unequal access for marginalized groups.
Cultural considerations in psychology: older theories often did not adequately account for culture; contemporary work emphasizes multicultural perspectives and ethical inclusivity in research and practice.
The role of neuroscience in understanding behavior: while informative, it should be integrated with psychological and behavioral data; avoid over-interpreting causality from imaging alone.
The evolution of psychology toward integrative approaches (biopsychosocial model) and positive applications (positive psychology) to promote well-being and resilience.
