Dr Yiyun Shou

BSc (Hons), PhD (Psychology)

I received PhD in Psychology (ANU) in 2015 and I am a current ARC DECRA fellow. Most of my research has been devoted to understanding people's reasoning, judgement and decision making under risk and ambiguity uncertainty. My current research focuses on understanding and measuring judgment and decision making under ambiguity uncertainty. I am also interested in psychometrics especially issues in cross-cultural measurement invariance, as well as statistical methods and modelling in psychology.

Some of my recent research topics include: 

  • Attitudes and decision making under risk and ambiguity
  • Cross-cultural measurement invariance of measures of psychopathic personality and related constructs
  • Modelling doubly bounded random variables
