IB Psychology SL study plan

IB Psychology SL · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Biological approach to behaviour

  • Map the biological approach syllabus: define the role of genes, neurotransmitters, hormones, and brain localisation in behaviour

  • Outline the structure and function of the nervous system and endocrine system, and explain neural transmission in your own words

  • Build a glossary of 25 core biological terms (e.g., neurotransmitter, synapse, hippocampus, cortisol, genotype) with one-line definitions

  • List the key biological studies you will use as evidence and record each study's aim, method, and finding in a comparison table

Your checkpoint

A one-page concept map linking genes, neurotransmitters, hormones, and brain structures to behaviour, plus a 25-term glossary

Week 2

Biological approach to behaviour

  • Explain how one or more techniques (e.g., fMRI, MRI, PET, EEG) are used to investigate the brain, noting strengths and limitations

  • Describe the effects of at least two neurotransmitters on behaviour and support each with a named study

  • Describe how at least one hormone influences behaviour and support it with a named study

  • Evaluate the use of animal models in biological research on behaviour

Your checkpoint

A 400-word written response comparing two research techniques, including one strength and one limitation for each

Week 3

Biological approach to behaviour

  • Explain localisation of function and neuroplasticity using at least two named studies

  • Describe the role of genetics in behaviour, distinguishing genotype, phenotype, and heritability

  • Evaluate the biological approach as a whole: reductionism, determinism, and ethical considerations

  • Draft three potential SAQ answers on biological topics from memory, then check against notes

Your checkpoint

Three timed 20-minute SAQ drafts (approx. 250 words each) on localisation, neurotransmitters, and genetics, self-marked against a rubric

Week 4

Biological approach to behaviour & Cognitive approach to behaviour

  • Consolidate Domain 1 by answering a full essay question under timed conditions

  • Map the cognitive approach syllabus: define models of memory, schema theory, and thinking and decision-making

  • Explain the multi-store model and working memory model, listing supporting evidence for each

  • Compare the two memory models in a side-by-side table

Your checkpoint

One timed 50-minute Domain 1 essay plus a completed memory-model comparison table

Week 5

Cognitive approach to behaviour

  • Explain schema theory and describe how schemas influence encoding, retrieval, and reconstruction of memory

  • Describe at least two cognitive biases or heuristics in thinking and decision-making, each with a supporting study

  • Explain how one cognitive research method (e.g., lab experiment, case study, interview) generates evidence about cognition

  • Evaluate the reliability and ecological validity of cognitive research

Your checkpoint

A 500-word evaluation of cognitive research methods with two concrete study examples

Week 6

Cognitive approach to behaviour & Sociocultural approach to behaviour

  • Explain the reliability of one or more cognitive processes (e.g., reconstructive memory) using named studies

  • Consolidate Domain 2 by writing two timed SAQs and one essay outline

  • Map the sociocultural approach syllabus: define social identity theory, social cognitive theory, and stereotyping

  • Describe how culture and cultural dimensions influence behaviour with at least one named study

Your checkpoint

Two timed Domain 2 SAQs plus a Domain 3 syllabus map with all key concepts defined

Week 7

Sociocultural approach to behaviour

  • Explain social identity theory and social cognitive theory, and apply each to a real-world example

  • Describe the formation of stereotypes and their effect on behaviour, citing at least two studies

  • Explain how one sociocultural research method (e.g., observation, survey, cross-cultural study) is used and evaluate its limitations

  • Evaluate the sociocultural approach: cultural bias, generalisability, and ethical issues in conformity research

Your checkpoint

A 600-word comparative essay plan contrasting social identity theory and social cognitive theory with evidence

Week 8

Biological approach to behaviour & Cognitive approach to behaviour & Sociocultural approach to behaviour

  • Review all three domains using a spaced-repetition schedule, prioritising weakest topics identified in earlier weeks

  • Practise one full essay per domain under exam timing (50 minutes each)

  • Write condensed one-page summary sheets for each domain

  • Complete a final self-assessment against the exam rubric and list three remaining gaps

Your checkpoint

Three timed full essays (one per domain) plus three one-page domain summary sheets

Milestones

Week 2: Can define and give a study example for every core biological concept without notes

Week 4: Completed one timed Domain 1 essay scoring at least 70% on the rubric

Week 6: Completed two timed Domain 2 SAQs and mapped all Domain 3 concepts

Week 8: Completed three timed full essays and identified no more than three remaining content gaps
