Carolyn Semmler is an Associate Professor and leads the Applied Cognition and Experimental Psychology (ACEP) group in the School of Psychology at the University of Adelaide. Her research focuses on the application of theories and models of cognition, judgment and decision-making to legal, intelligence and medical contexts. Dr. Semmler’s work has been cited over 1000 times in leading journals as well as legal cases in Australia and the United States. She has also contributed to a comprehensive guide on the application of cognitive psychology to issues of hearing and sound in legal domains, providing guidance on the science behind this expert evidence that is presented in both civil and criminal proceedings in Australian courts. Dr. Semmler has contributed to the development of computational models of eyewitness memory, allowing accurate measurement of memory in applied contexts. Her work has also explored the conditions under which feedback distorts the memory reports of witnesses, and she has contributed to improvements in juror comprehension of legal instructions, as well as the impact of mood and emotion on juror decision making. Her most recent work has explored the impact of face matching technology on human decision making, which has implications for the understanding of bias in the use of automated face matching in legal and investigatory contexts.
