  • About

    Broadly speaking, I am interested in the applied domains of cognitive psychology such as the role of executive functions in eyewitness memory errors, and individual differences in the ability of people to improve executive functions through training. I completed my Ph.D. in Psychology at the Victoria University of Wellington in Wellington, New Zealand.

    My postgraduate research focused on the cognitive and social factors that affect people's susceptibility to memory distortions-particularly as it relates to eyewitness memory and juror decision making. In the Attention and Working Memory Lab, my interests have extended to understanding the role of executive functions-particularly working memory capacity and attention control-in predicting a person's capacity to benefit from cognitive training. Combining these two fields, I work with colleagues in Australia and New Zealand to investigate the role of executive functions-like working memory capacity-in memory distortions and people's likelihood of engaging in intrusive thoughts of traumatic images.

    In addition to my experimental work, I also develop web-based experiments and web-based tools for experimental researchers. More information about these tools can be found at and at
