Psychology

Profile

Samantha graduated from the University of Portsmouth in 1997 with a BSc (Hons) Psychology degree, which ended in the final year project ‘Deceiving and Detecting Deceit when the Stakes are High: The Behaviour of a Murderer During Police Interviews Analysed’. Continuing her interest in deceptive behaviour, she then commenced research for a PhD (funded by the ESRC), which involved analysing the behaviour of high-stake liars and truth-tellers, specifically videos of suspects in their police interviews. She then showed clips of these suspects to police officers to see if they could tell when they were lying or truth-telling. This research culminated in her thesis ‘Suspects, lies and videotape: An investigation into telling and detecting lies in police/suspect interviews’ in 2001.

After a couple of years in research posts outside academia, Sam returned to Portsmouth in 2003 to embark on a 3-year ESRC project with Professor Vrij on enhancing deception detection through increasing cognitive load in interview situations. She has just commenced another project with Vrij designed to facilitate lie detection in interview situations.

Her current research interests include:
    •     Nonverbal cues to deception
    •     People’s perceptions of deceptive behaviour
    •     Professional lie detectors’ ability to detect deceit
    •     Enhancing interview situations in order to facilitate deception detection
    •     Speech related cues to deception (Reality Monitoring)
