Decision Making: Theory and Practice


Entry requirements

Open to master’s students in Psychology with specialisation Applied Cognitive Psychology and other master’s students in Psychology.


Shall I buy a travel insurance? Shall I go to the party if Mary doesn’t? Is this person guilty? And should I worry about this medical test outcome? We all face a perplexing array of judgments and decisions every day. In this course, we review the main theories in judgment and decision making, and we consider applications in both every day and professional decision problems.

Course objectives

  • Being introduced in the formal and psychological science of judgment and decision making

  • Being introduced in 3 fields of application: medical, legal and administrative decision making (in particular game theory).

Mode of instruction

Eight lectures (including guest lectures from professional decision making experts).

Assessment method

The examination consists of two parts:

  • A multiple-choice examination of 30 questions on Newell et al’s book

  • An essay examination (open questions) about papers.
    The two components are tested simultaneously. The final grade is a combination of the multiple-choice examination grade (70%) and the essay examination grade (30%). A higher grade in one component can be used to compensate for a fail in another component. A grade for a unit of assessment that is no lower than 4.5 can be compensated by a grade for the other unit of assessment.

The Faculty of Social and Behavioural Sciences has instituted that instructors use a software programme for the systematic detection of plagiarism in students’ written work. In case of fraud disciplinary actions will be taken. Please see the information concerning fraud.
