Cambridge Syllabus Notes

AS Level Approaches to Psychology

The Cambridge A‑Level Psychology (9990) syllabus requires students to understand the major theoretical approaches that underpin psychological research and practice. These approaches provide different lenses through which behaviour, cognition and emotion are interpreted. The following notes outline the key approaches, their core concepts, major contributors, strengths, limitations and typical applications.

1. Behaviourist Approach

The behaviourist approach focuses on observable behaviour and the environmental factors that shape it. It rejects introspection and internal mental states as subjects of scientific study.

Key Concepts: Classical conditioning, operant conditioning, reinforcement, punishment, stimulus‑response (S‑R) associations.
Major Researchers: Ivan Pavlov, John B. Watson, B.F. Skinner.
Typical Applications: Behaviour therapy, classroom management, animal training.

2. Cognitive Approach

The cognitive approach examines internal mental processes such as perception, memory, thinking and problem‑solving. It treats the mind as an information‑processing system.

Key Concepts: Information processing, schemas, cognitive restructuring, working memory, dual‑process theory.
Major Researchers: Jean Piaget, Ulric Neisser, Aaron B. T. Clark, Daniel Kahneman.
Typical Applications: Cognitive‑behavioural therapy (CBT), educational psychology, eyewitness testimony research.

3. Humanistic Approach

The humanistic approach emphasises personal growth, free will and the inherent goodness of people. It views individuals as active agents capable of self‑directed change.

Key Concepts: Self‑actualisation, unconditional positive regard, client‑centred therapy, hierarchy of needs.
Major Researchers: Carl Rogers, Abraham Maslow.
Typical Applications: Person‑centred counselling, positive psychology interventions, educational settings that promote autonomy.

4. Biological (Neuroscientific) Approach

The biological approach investigates the physiological bases of behaviour, including brain structures, neurotransmitters and genetics.

Key Concepts: Neurotransmission, brain localisation, genetic inheritance, hormone effects, neuroplasticity.
Major Researchers: Roger Sperry, Paul Broca, James Olds, Michael Gazzaniga.
Typical Applications: Pharmacotherapy, neuroimaging research, genetic counselling.

5. Psychodynamic Approach

The psychodynamic approach, rooted in psychoanalytic theory, explores how unconscious processes, early childhood experiences and internal conflicts influence behaviour.

Key Concepts: Unconscious mind, defence mechanisms, psychosexual stages, transference, id‑ego‑superego.
Major Researchers: Sigmund Freud, Carl Jung, Melanie Klein, Erik Erikson.
Typical Applications: Psycho‑analysis, psychodynamic psychotherapy, case‑study research.

6. Sociocultural Approach

The sociocultural approach examines how social, cultural and environmental contexts shape behaviour and mental processes.

Key Concepts: Social norms, cultural scripts, conformity, social identity, acculturation.
Major Researchers: Lev \cdot ygotsky, Stanley Milgram, Solomon Asch, Henri Tajfel.
Typical Applications: Cross‑cultural research, community psychology, anti‑discrimination programmes.

Comparative Summary of Approaches

Approach	Focus of Study	Methodological Preference	Strengths	Limitations
Behaviourist	Observable behaviour and environmental contingencies	Laboratory experiments, controlled observation	High reliability; clear cause‑effect relationships	Ignores mental processes; limited ecological validity
Cognitive	Internal mental processes (thinking, memory, perception)	Experimental tasks, computer modelling, neuroimaging	Explains complex behaviours; integrates with neuroscience	Reliance on indirect measures; can be overly mechanistic
Humanistic	Subjective experience, personal growth, self‑concept	Qualitative interviews, case studies, self‑report questionnaires	Emphasises individual agency; therapeutic empathy	Less empirical rigor; difficult to falsify
Biological	Physiological mechanisms underlying behaviour	Neuroimaging, pharmacological studies, genetics	Strong explanatory power for disorders; objective data	Reductionist; ethical constraints on invasive methods
Psychodynamic	Unconscious motives, early experiences, intrapsychic conflict	Case studies, projective tests, longitudinal observation	Depth of insight into personality; therapeutic depth	Subjective interpretation; limited replicability
Sociocultural	Social and cultural influences on behaviour	Cross‑cultural surveys, field experiments, ethnography	Highlights contextual factors; relevance to policy	Complex variables; difficulty isolating causality

Applying the Approaches in Research and Practice

Choosing an Approach: Researchers select an approach based on the research question, feasibility of measurement, and ethical considerations. For example, a study on habit formation may favour a behaviourist design, whereas an investigation of memory distortions would align with the cognitive approach.
Integrative (Biopsychosocial) Models: Modern psychology often combines elements from multiple approaches to provide a more comprehensive explanation. The biopsychosocial model integrates biological, psychological (cognitive/behavioural) and social factors.
Therapeutic Implications: Practitioners match therapeutic techniques to the client’s presenting problems and preferences. A client with anxiety might benefit from CBT (cognitive‑behavioural), while another seeking personal meaning may prefer humanistic counselling.
Ethical Considerations: Each approach raises specific ethical issues—e.g., behaviourist experiments with animals, invasive neuroimaging, or the confidentiality of psychodynamic case work. Ethical guidelines must be adhered to across all methods.
