Why Psychological and Behavioural Sciences at University of Cambridge?

Cambridge Psychological and Behavioural Sciences is the official course title on the current Undergraduate Study page.

The structure is a reason to take PBS seriously: Year 1 includes experimental psychology, social psychology and research-methods training before later specialisation.

Because the degree deliberately spans experimental, social and interdisciplinary papers, the strongest applicants usually show that they can move between biological, cognitive and social explanations without treating any one of them as the whole answer.

Admissions Test

Cambridge lists PBS under “College admission assessment”, not a centrally registered admissions test.

For PBS, the current College-assessment note names Selwyn and St Edmund's as Colleges that ask applicants to take an assessment, and Cambridge says details are provided by the relevant College. Applicants should still check their intended College page because College-specific requirements and instructions can change.

Applicants do not need to register in advance for this College admission assessment.

For international applicants, the practical point is simple: College instructions matter, because the assessment is arranged through the relevant College rather than a national test sitting.

Check the College page before choosing a College, especially if you are applying from a qualification system where interview logistics already need careful planning.

Question Types You’ll See

discussion of your academic interestsquestions about unfamiliar materialreasoning aloud in an academic conversation

Cambridge describes interviews as academic conversations.

The interview may ask you to discuss academic interests, respond to unfamiliar material, and reason aloud in an academic conversation.

What matters is not sounding polished. It helps to slow down, define terms, test an explanation, and adjust when the interviewer gives you a new piece of information.

  • Personal Statement10%
  • Contextual Factors5%

Indicative — exact balance varies by college and year.

Cambridge describes admissions decisions as holistic and based on all available information.

The decision-weight percentages in the visual are editorial estimates only, because Cambridge does not publish numerical weights.

In reality, PBS applicants need evidence across the file: subject preparation, clear thinking, good academic trajectory and enough flexibility to handle unfamiliar material.

Personal Statement Tips

Do not make the personal statement a list of famous experiments. Use one or two ideas to show how you think.

A strong PBS paragraph usually starts with a question, gives the evidence you read, and then explains what became more complicated. That is better than saying you have always been fascinated by people.

The course overlaps with anthropology, neuroscience, philosophy and sociology, so it helps to show how you handle connections between disciplines.

Use school psychology, biology, maths or social-science work carefully. The point is not to prove you already know the degree; it is to show that you can ask a precise question and follow evidence.

Supercurriculars & Competitions

Projects

A useful PBS project is not large or dramatic; it is controlled enough for you to explain methods and limits.

Do not overclaim from a tiny sample. Reflection matters more than pretending your project proves a general law of behaviour.

How to present a project:

  1. Why you did it
  2. What the project is
  3. How you did it
  4. What went wrong
  5. What you did about it
  6. What you learned
  • Replicate a classic cognitive effect ethically: Design a small, low-risk study around a well-known effect such as Stroop interference, framing, anchoring or memory recall. Focus on hypothesis design, controls, consent, anonymised data, confounds and cautious interpretation.
  • Behaviour-change evidence review: Choose one everyday behaviour, such as sleep hygiene, phone use, exercise adherence or procrastination. Compare psychological theories and empirical studies, then propose a modest intervention and how you would evaluate it.
  • Developmental or social psychology research map: Track how one question is studied across laboratory experiments, surveys, longitudinal work and cross-cultural research.

Other Supercurriculars

Other supercurricular work should strengthen your thinking, not decorate the application.

  • Primary-research reading: Move beyond popular psychology by reading abstracts, methods and limitations sections from journal papers.
  • Research methods and statistics: Build confidence with variables, correlations, sampling, p-values, effect sizes and replication.
  • Ethics and consent: When doing any independent project, avoid sensitive personal data and clinical claims.
  • Interdisciplinary links: Connect psychology to neuroscience, anthropology, philosophy, education, sociology or computational modelling.
  • Reflective volunteering or observation: Volunteering can be useful if reflection stays analytical.
  • Writing and discussion: Practise short essays that weigh evidence on both sides of a behavioural claim.

These are support, not substitute. A weaker activity becomes useful when you can analyse it carefully.

Competitions

Competitions are not required, but they can stretch your writing, research habits and evidence evaluation. Choose one that genuinely develops your PBS thinking.

  1. John Locke Institute Global Essay Prize — Independent argument and essay writing. Choose a behavioural or psychology-adjacent question and build a source-led argument.
  2. Trinity College Cambridge Essay Prizes — Academic essay writing for school students. Use it as practice in disciplined, source-led argument.
  3. UK Brain Bee — Neuroscience knowledge for secondary/high-school students. Work through brain and nervous-system fundamentals.
  4. British Biology Olympiad — High-level biology reasoning relevant to biological psychology/neuroscience. Prioritise neurobiology, evolution and experimental interpretation.
  5. Nuffield Research Placements — Research curiosity and project experience. Apply with a focused research interest and reflect on methods and limitations.

None are required; one or two done well beats five half-attempted.

Section 11

Building Psychological and Behavioural Sciences Knowledge

Thinking, Fast and Slow is useful for judgement and decision-making, while Social Cognition: From Brains to Culture gives a tighter route into social cognition.

YaleCourses hosts Paul Bloom's psychology lectures, CrashCourse gives short reviews of core psychology topics, and American Psychological Association gives research and applied psychology context.

Speaking of Psychology and Under the Cortex are better for research-led topic choice than generic psychology clips.

Introduction to Psychology and Starting with psychology are structured starting points for broad psychology foundations and the vocabulary needed to discuss methods, evidence and limitations.

A good preparation pattern is one book, one lecture series and one research-methods habit. After each resource, write short notes on method, evidence and limitations.

College Choice & Reallocation

29 colleges offer this subject. 19% of places come through the pool.

PBS is available at all Colleges except Peterhouse on the current course page.

College choice affects where you are assessed first and can affect practical details such as interview format, College-specific assessment and submitted-work instructions.

Cambridge's Winter Pool is an inter-College moderation process, and around 19% of October 2024 applications were placed in the Winter Pool.

Choose a College for practical fit, not for a guessed admissions advantage. The safer question is whether you understand its PBS assessment and submitted-work requirements.
