About OxfordAQA International A Level Psychology 3.4.2 Issues and Debates in Psychology
Issues and debates in psychology is the second section of Unit 4, Approaches and application, on the OxfordAQA International A2 Psychology course. It asks you to step back and think about psychology as a whole. You study the free will and determinism debate, including hard and soft determinism and biological and environmental determinism; the nature-nurture debate and interactionism; holism and reductionism, including levels of explanation; and psychology as a science, including objectivity, the empirical method, replicability, falsifiability, theory construction and hypothesis testing. Because the unit is synoptic, examiners expect you to illustrate each debate with examples from topics such as memory, schizophrenia, social influence and the approaches.
What you need to know
- Free will and determinism Hard determinism says all behaviour has causes outside our control; soft determinism accepts behaviour has causes but allows some conscious choice. Biological determinism focuses on genes and brain; environmental determinism focuses on conditioning. Determinism fits the scientific search for causal explanations.
- Nature and nurture Nature refers to inherited influences; nurture to environmental influences and learning. Interactionism, as in the diathesis-stress model, sees behaviour as the result of both, for example genetic vulnerability triggered by stress in schizophrenia.
- Holism and reductionism Reductionism breaks behaviour into simpler components, such as biological reductionism (neurotransmitters) and stimulus-response reductionism (conditioning). Holism argues behaviour must be studied as a whole. Levels of explanation range from biological to social and cultural.
- Psychology as a science Key features are objectivity, the empirical method, replicability, falsifiability (Popper) and theory construction through hypothesis testing. Some areas, such as laboratory memory research, fit these features well; others, such as subjective experience, fit less well.
- Using examples Every debate answer should be illustrated with specific topics: Milgram's situational variables for environmental influences, dopamine for biological reductionism, twin studies for nature and nurture, and research methods for scientific features.
Common mistakes in 3.4.2 Issues and Debates in Psychology
- Saying a theory is either deterministic or not. Many positions, such as soft determinism or interactionism, sit between the extremes.
- Treating reductionism as simply bad. It allows precise testing and has led to effective treatments, though it may ignore important higher-level factors.
- Describing falsifiability as proving a theory false. It means a theory must be capable of being shown to be false by evidence.
- Writing about a debate in the abstract without examples from the specification topics.
- Concluding that psychology is or is not a science without considering that different areas differ in how scientific they are.
Try three 3.4.2 Issues and Debates in Psychology exam-style questions
1. Explain what is meant by soft determinism. (2 marks)
Show the mark scheme answer
The view that behaviour has causes, but that people still have some conscious control and can make choices within the limits set by those causes.
2. Using an example from psychology, explain what is meant by biological reductionism. (3 marks)
Show the mark scheme answer
Biological reductionism explains complex behaviour in terms of its biological components, such as neurotransmitters, genes or brain structures; e.g. explaining schizophrenia in terms of excess dopamine activity; this ignores psychological and social factors such as stress or family environment.
3. Discuss the extent to which psychology can be considered a science. (16 marks)
Show the mark scheme answer
A strong answer would explain features of science (objectivity, empirical method, replicability, falsifiability, hypothesis testing) and show where psychology meets them, such as controlled laboratory experiments on memory; then evaluate problems such as demand characteristics, difficulty measuring subjective experience, replication problems and the role of paradigms; and conclude that different areas of psychology are scientific to different degrees.
3.4.2 Issues and Debates in Psychology FAQs
What does OxfordAQA International A Level Psychology 3.4.2 Issues and Debates in Psychology cover?
It covers free will and determinism, the nature-nurture debate, holism and reductionism, and the features of psychology as a science.
Which unit is 3.4.2 Issues and Debates in Psychology examined in?
It is examined in Unit 4 (PS04), Approaches and application, a synoptic unit with three compulsory sections.
How do I write a strong issues and debates essay?
Explain both sides of the debate clearly, then support every point with an example from a specific topic you have studied. Finish with a reasoned judgement, often recognising that a middle position such as interactionism or soft determinism fits the evidence best.
