IB Psychology HL study plan

IB Psychology HL · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Biological approach to understanding behaviour (core) & Internal assessment: experimental study design, data analysis and report writing

  • Map the biological approach's core topics-localisation of function, neuroplasticity and neurotransmitters, hormones and pheromones, and genetics and evolution-to at least two named studies each, recording the IV, DV, method, one strength and one limitation.

  • Design an IA experiment by specifying an independent variable, a dependent variable, an operationalised measurement, a sampling method, at least four controls and four ethical considerations.

  • Draft the IA introduction with a clear aim, one testable hypothesis and a 120-word link to a named theory or model.

  • Complete a 20-item retrieval quiz on biological research techniques (MRI, fMRI, PET, EEG, CAT, post-mortem) and score at least 80%.

Your checkpoint

One-page IA proposal plus a study matrix covering eight biological studies, checked against a 12-point checklist.

Week 2

Biological approach to understanding behaviour (core) & Cognitive approach to understanding behaviour (core)

  • Evaluate two neurotransmitter or hormone studies by writing the conclusion, one methodological limitation and one alternative explanation for each.

  • Compare the multi-store model and working memory model using a labelled diagram and a 200-word contrast of capacity, duration, encoding and forgetting.

  • Apply schema theory to one eyewitness scenario, predicting two distortions and justifying each with a named study.

  • Score a 22-mark Paper 1 Section B essay on a biological topic against the markbands, then rewrite the weakest paragraph.

Your checkpoint

Timed 40-minute biological essay scored with a completed markband checklist and one rewritten paragraph.

Week 3

Cognitive approach to understanding behaviour (core) & Sociocultural approach to understanding behaviour (core)

  • Evaluate reconstructive-memory and thinking-and-decision-making evidence by identifying one bias or error and the study supporting it.

  • Construct a sociocultural concept map linking social identity theory, social cognitive theory, stereotypes and culture.

  • Explain one study of conformity or group dynamics, naming the research method, sample, procedure and one ethical issue.

  • Write two 9-mark SAQ plans, one cognitive and one sociocultural, each using the command term, three evidence points and a conclusion.

Your checkpoint

Two SAQ plans plus a one-page cognitive–sociocultural comparison table, self-marked against SAQ criteria.

Week 4

Sociocultural approach to understanding behaviour (core) & Research methodology and qualitative research (HL Paper 3)

  • Evaluate two sociocultural studies of culture and behaviour, including one cross-cultural study and one acculturation or enculturation study.

  • Distinguish qualitative methods-interviews, observations, case studies and focus groups-by purpose, data type, researcher role and ethical demand.

  • Conduct a thematic analysis of a short qualitative transcript, producing three themes with supporting quotations.

  • Answer a Paper 3 qualitative question on credibility, transferability or triangulation in 20 minutes.

Your checkpoint

Paper 3 qualitative response scored at 15/20 or higher, plus a methods comparison table.

Week 5

Options (one studied): abnormal psychology, developmental psychology, health psychology, human relationships, or sport psychology & Internal assessment: experimental study design, data analysis and report writing

  • Declare your option and map its three prescribed content areas to at least six studies, noting one strength and one limitation per study.

  • Collect IA data from at least 15 participants using the approved procedure and log informed consent.

  • Calculate descriptive statistics-mean, median, mode and standard deviation-and create one appropriately labelled graph.

  • Apply one inferential test, such as Mann–Whitney U or Wilcoxon, and state the result in APA-style wording.

Your checkpoint

Clean IA data file with descriptive statistics, graph and a one-paragraph results draft.

Week 6

Options (one studied): abnormal psychology, developmental psychology, health psychology, human relationships, or sport psychology & Research methodology and qualitative research (HL Paper 3)

  • Evaluate two option treatments or interventions using efficacy, ethical and cultural criteria.

  • Complete a Paper 3 quantitative section, interpreting a mean, standard deviation, p-value and effect size in context.

  • Compare qualitative and quantitative evidence on one option topic and recommend a research design.

  • Write a 22-mark option essay plan with three body paragraphs and a counter-argument.

Your checkpoint

Full Paper 3 mock covering both sections, completed in 60 minutes and scored.

Week 7

Biological approach to understanding behaviour (core) & Cognitive approach to understanding behaviour (core) & Sociocultural approach to understanding behaviour (core)

  • Synthesize the three core approaches by comparing how each explains one behaviour, such as aggression or memory.

  • Complete 10 SAQ outlines across all core domains using a 6-minute timer per outline.

  • Write two full Paper 1 Section B essays under exam conditions and mark them with the markbands.

  • Update an error log with every missed command term and content gap.

Your checkpoint

Error log with 15 entries and two timed essays scored at 12/22 or higher.

Week 8

Options (one studied): abnormal psychology, developmental psychology, health psychology, human relationships, or sport psychology & Internal assessment: experimental study design, data analysis and report writing & Research methodology and qualitative research (HL Paper 3)

  • Finalize the IA report-introduction, method, results, discussion, references and appendices-and check it against the moderation checklist.

  • Complete a full Paper 1 and Paper 2 mock under timed conditions.

  • Reread the Paper 3 mark scheme and redraft the weakest answer.

  • Consolidate one-page summaries for all six domains and rehearse key definitions aloud.

Your checkpoint

Submission-ready IA plus a scored mock exam report identifying three final actions.
