Signal-detection theory and associated analyses (e.g. ROC analyses) have guided thinking in experimental psychology from before the 1950s. In our research, we use this theoretical framework to predict and explain applied memory findings. We are also advancing new ways to measure elements of memory performance (e.g., discrimination accuracy, response bias), in applied eyewitness memory tasks.
Key questions include:
-How can signal-detection theory be used to explain and analyse eyewitness memory?
-What methods should we use to measure memory performance?
