Paper 1 section A guidance

  • Paper 1 is taken by both HL and SL Psychology students

  • You will be given 1 hour and 30 minutes to complete Paper 1

  • Paper 1 has 3 sections:

    • Section A

    • Section B

    • Section C

  • Paper 1 is weighted at 25% for SL

  • Paper 1 is weighted at 35% for HL

  • Paper 1 is worth 35 marks in total

Section A: short-answer questions (SAQs)

  • Section A consists of two compulsory SAQs from two of the three content areas

    • Biological approach

    • Cognitive approach

    • Sociocultural approach

  • The SAQs are worth 4 marks each

    • The total for Section A is 8 marks

  • The examiners are looking for:

    • how well you demonstrate knowledge and understanding of theories and concepts

    • how well you can develop each answer you give

    • the use of examples to illustrate points

Topics covered

  • Biological approach:

    • Animal models, biological reductionism, brain imaging techniques, chemical messengers, diathesis-stress, genetics, localisation of function, neuroplasticity and neurotransmission

  • Cognitive approach:

    • Anchoring bias, classical conditioning, cognitive load theory, cognitive models, confirmation bias, dual process model, operant conditioning, and schema theory

  • Sociocultural approach:

    • cognitive dissonance, compliance techniques, conformity, cultural dimensions, emic/etic approaches, enculturation, acculturation, social identity theory and social learning theory

Example questions

  • Describe the role of one chemical messenger in human behaviour [4 marks]

  • Explain the role of classical conditioning in behaviour [4 marks]

  • Describe conformity and its role in understanding human behaviour [4 marks]

Examiner Tips and Tricks

You are not required to use research studies in your answers — you can use hypothetical examples to develop and illustrate your points. This means you don’t need to memorise every detail of specific studies.

However, including studies can strengthen your answer by providing a solid foundation for explaining or applying a theory.

Paper 1 section B guidance

Section B: short-answer questions (SAQs)

  • Section B consists of two compulsory SAQs from two of the four contexts

    • Health and wellbeing

    • Human development

    • Human relationships

    • Learning and cognition

  • The SAQs are worth 6 marks each

    • The total for Section B is 12 marks

  • The examiners are looking for:

    • how well you use the given scenario in your answer

    • how well you apply your knowledge clearly and logically to the context provided

Example question

  • In a study, MRI scans were used to determine grey matter density. With reference to this study, explain the use of brain-imaging techniques in understanding human behaviour [6 marks]

Examiner Tips and Tricks

You do not have to use any research studies to answer Section B questions, as the research scenario is provided. Make sure that you use this scenario to inform your answer, since the main skill assessed in Section B is application (AO2).

Paper 1 section C guidance

Section C: extended-response questions (ERQs)

  • Section C consists of two optional ERQs from two of the four contexts

    • Health and wellbeing

    • Human development

    • Human relationships

    • Learning and cognition

  • The questions are concept-based so are framed around themes such as:

    • bias

    • causality

    • change

    • measurement

    • perspective

    • responsibility

  • The ERQs are worth 15 marks each

    • The total for Section C is 15 marks, as you only answer one ERQ

  • The examiners are looking for:

    • how well you show breadth and depth of knowledge, using studies and theory

    • how well you provide a balanced evaluation (strengths, limitations, counterarguments, applications)

    • a clear structure, e.g.,

      • Introduction

      • AO1: theory/evidence

      • AO3: evaluation (strengths and limitations)

      • Conclusion

Example questions

  • In the context of human development, evaluate one or more strategies used by developmental psychologists to measure theory of mind [15 marks]

  • One claim in the psychology of health and wellbeing is that a single perspective is not enough to explain mental health

    • Discuss this claim with reference to one biological explanation of one or more disorders [15 marks]

  • In the context of learning and cognition, discuss the role of responsibility in the effect of brain damage on memory [15 marks]

  • Evaluate the importance of communication with reference to changes in interpersonal human relationships [15 marks]

Examiner Tips and Tricks

You only need to answer one of the two questions on offer. Be very careful not to answer both questions, as you will only be marked on the first answer you give.
