This module examines several psychological theories related to the process of investigation and critical incident management. The aim of this module is to provide students with an overview of the relevant psychological theories to understand how a range of organisational, situational, individual and social factors may affect decision-making, leadership and communication processes within investigations and critical incident management. The module will be taught via a range of activities including lectures, seminars, tutorials, and laboratory work. Learning will be assessed via a critical evaluation of current theoretical explanations for the management of major investigations or critical incidents and a practical assignment based on case materials provided.
