BSc Psychological and Behavioural Science

Why do people think and behave the way they do in certain situations? What role does our environment have on decision-making? How does an individual’s behaviour affect wider society? These are all questions explored on our BSc Psychological and Behavioural Science.

This programme is unusual in bringing together psychology and behavioural science in one degree and exploring these subjects from both social science and natural science perspectives. As well as developing your core knowledge, you’ll learn how psychological and behavioural science theories can be applied in the real world to address social issues in areas such as health and education.

You’ll learn how to conduct high-quality empirical research, including research design and qualitative approaches such as interviews and focus groups. You’ll also study statistical analysis and interpretation and learn how to present your findings effectively.

LSE was recently ranked number one in the UK for Psychology in the Good University Guide 2026 and number one in London in the Complete University Guide 2026. Our graduates progress to rewarding and interesting careers in government, NGOs and the private sector – contributing to national and international policy debates.

The Department of Psychological and Behavioural Science is a growing community of researchers, academics and students who explore the human mind and behaviour in a societal context.

From the world to the lab and back again

Formative coursework

All taught courses include formative coursework, which is not assessed. This helps prepare you for summative assessment. We use a wide range of formative assessment methods, such as essays, case studies, reports, quizzes and mock exams.

Feedback on coursework is an essential part of the learning experience. Class teachers mark formative coursework and feedback is normally given within two weeks – provided the work is submitted on time.

Summative assessment

This assessment counts towards your final course mark and degree award.

Summative assessment usually involves a written examination for each course at the end of the academic year. Some courses also have written examinations in January while others are assessed partly by essays or other work submitted during the year.

Assessment on individual courses can change from year to year. Read more about the current formative coursework and summative assessment for each course in the relevant course guide.
