Approaches and biopsychology revision notes

Approaches and biopsychology

Specification context

Approaches and biopsychology appears in AQA A-level Psychology 7182.

Topic overview

Students study major psychological approaches, biological systems, brain investigation methods and localisation of function. Revise this area by separating AO1 knowledge, AO2 application and AO3 evaluation. Psychology answers need accurate terminology, relevant evidence and clear judgement, not just a list of named studies.

Learning objectives

• Explain social learning theory, including imitation, identification, vicarious reinforcement, mediational processes and Bandura's research.
• Explain the cognitive approach, including internal mental processes, schema, models and inference.
• Explain the biological approach, including genotype, phenotype, evolution, biological structures, neurochemistry and cognitive neuroscience.
• Explain the psychodynamic approach, including the unconscious, Id, Ego, Superego, defence mechanisms and psychosexual stages.
• Explain humanistic psychology, including free will, self-actualisation, Maslow's hierarchy of needs, congruence and conditions of worth.

Objective-by-objective revision

Approaches in Psychology: Explain the behaviourist approach, including classical conditioning, Pavlov's research, operant conditioning, reinforcement and Skinner's research.

Start with AO1: define the psychological concept, theory, study, method, treatment or data issue named in this objective. Use precise Psychology terminology and keep the wording tied to Approaches in Psychology. Then build AO2 or AO3 where relevant. AO2 applies the idea to a scenario, practical context, qualitative data or quantitative data. AO3 analyses, interprets or evaluates by explaining why evidence, validity, reliability, bias, ethics, generalisability or methodology affects the conclusion. A strong answer avoids unsupported opinion and study-name dumping. It links claim, evidence, method and implication so the evaluation explains why the point matters.

Exam focus

For shorter answers, define the concept and use the command word precisely. For extended answers, build a chain: point, evidence, explanation, evaluation and conclusion. If the topic uses research methods or statistics, distinguish experiment from correlation, validity from reliability, qualitative from quantitative data, and significance from practical importance.

AO1 knowledge routine

AO1 is secure when the answer names the psychological concept, gives a precise definition and uses the vocabulary expected by the specification. In this topic, students should avoid writing broad everyday explanations. Each definition should connect to a theory, study, method, biological process, cognitive process, treatment or data issue where the learning objective requires it. Strong AO1 also means selecting relevant detail: a short answer may only need one accurate term, while an extended answer may need a sequence of linked ideas.

AO2 application routine

AO2 is needed when the question gives a stem, scenario, practical context, qualitative material or quantitative data. The answer should not repeat the scenario. It should select the relevant detail and explain how the psychological concept applies to it. If the question includes behaviour, participants, results or data, use those details directly before moving into evaluation. This keeps application separate from description and helps the answer stay anchored to the question.

AO3 evaluation routine

AO3 should explain the impact of evidence rather than merely naming a strength or limitation. A useful structure is: make the evaluative point, give the evidence or method detail, explain why it matters and finish with a judgement. For example, a validity issue matters because it affects whether the findings measure what they claim to measure. A reliability issue matters because it affects consistency. Bias matters because it can limit generalisability or create an unbalanced conclusion.

Common mistakes to avoid

• Do not describe a study and assume that counts as AO3 evaluation.
• Do not claim correlation proves causation.
• Do not treat explanation and treatment as the same thing.
• Do not use generic evaluation words unless you explain why the limitation or strength matters.
• Do not mix Paper 3 option groups when answering an option question.

Revision strategy

Use flashcards for AO1 definitions, MCQs for misconceptions, and short written answers for evidence-evaluation chains. After each answer, check whether you have separated description from evaluation and whether your conclusion follows from the evidence.

Final self-check

Before leaving this topic, write one answer that only describes, one answer that applies and one answer that evaluates. Label the AO used in each sentence. If an evaluation sentence could fit any Psychology topic, make it more specific by adding the study, method, validity issue, reliability issue, ethical issue or data implication. This final check prevents generic writing and prepares students for questions that combine knowledge, application and evaluation in one response.

Building stronger paragraphs

A reliable paragraph structure is point, evidence, reasoning and judgement. The point should name the psychological idea. The evidence should be specific enough to show that the answer is not guessing. The reasoning should explain how the evidence supports, challenges or limits the claim. The judgement should say what this means for confidence in the explanation, method or treatment. This structure is especially useful when the question asks students to discuss or evaluate, because it prevents long descriptive paragraphs that never become analytical.

Method and evidence checks

When evidence comes from research, check the method before writing the conclusion. Experiments can support cause-and-effect reasoning when variables are controlled, but correlations only show relationships. Samples affect generalisability, controls affect internal validity, and repeated or standardised procedures affect reliability. These checks help students explain why evidence is strong or limited rather than simply saying that a study supports the topic.

Making conclusions precise

A conclusion should follow from the evidence already used. If the evidence is limited by bias or weak validity, the conclusion should be cautious. If the evidence is consistent and methodologically strong, the conclusion can be more confident. This does not mean writing a long final paragraph every time; it means ending the answer with a clear implication that matches the quality of the evidence.
