Research and consultancy

Research interests

My research is primarily focused on applied and theoretical aspects of metacognition. Theoretically oriented projects include investigations of: monitoring and control processes in recognition memory and mechanisms underlying positive versus negative recognition decisions. My applied work includes projects examining: processes and factors underlying a witness's decision to make an identification from a line-up; regulation of grain size and reporting of eyewitness testimony; and predictors (e.g., confidence and response latency) of identification accuracy.

Postgraduate research supervision

Nicky Guerin

Rachel Hiller
Project title: Gender differences in the development of theory-of-mind and executive functioning in typically developing and autistic pre-school aged children

Caitlin Hitchcock
Project title: Overgeneral autobiographical memory in children who have experienced trauma

Potential PhD Projects:

(1)  testing/developing theories of recognition in complex tasks (e.g., lineup decisions)

(2)  theories of monitoring (e.g., confidence judgments) and control (e.g., decisions to report an answer or say "don't know") of memory

(3)  applying the above theories to improve eyewitness evidence (eyewitness testimony from interviews or eyewitness identifications from lineups)
