I am interested in memory, and how people make decisions based upon their memorial experiences. I have an interest in ‘basic’ face recognition/perception, as well as a more applied interest in eyewitness identification. I am also interested in metacognition – i.e., ‘thinking about thinking’ – particularly as it relates to the confidence people express about their memory-based decisions, and the relationship that confidence has to accuracy.

  • PSY319 Final Year Independent Research Project

    Students conduct an independent research project under the supervision of a member of staff. The research topic is decided in conjunction with supervisors and Research topics. Students must obtain ethical approval, design, conduct, analyse and write up a piece of research in order to achieve Graduate Basis for Chartership with the British Psychological Society (BPS).

  • PSY320 Dissertation

    This optional module provides students with the opportunity to conduct an extended literature review to discover what is currently known about an interesting, but less well known, area of psychology that is not taught as part of the psychology curriculum in Level 5 or 6. Students work independently, guided by their dissertation supervisor, to research a topic of their choice. In recent years students have written dissertations about `political psychology¿, `positive psychology¿ `why people take part in extreme sports¿, `does cannabis use cause schizophrenia¿ and many other diverse lines of enquiry.

  • PSY350 Investigative Psychology

    This module will explore the application of psychological theories and research to police investigations. We will discuss how our theoretical understanding of human cognition, including perception, memory, and decision-making, have led to changes in police procedure that have improved the reliability of the investigative process. Specific topics will include: Eyewitness testimony and identification; False confessions; Detecting deception; and cognitive biases in forensic evidence processing.
