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.
