Current Research

Our research seeks to understand basic processes in recognition memory and reasoning, using methods rooted in signal detection theory and neuroscience (EEG). We view computational models as essential tools for interpreting data.

ROC Stats

Sampling distributions of ROC statistics (Macmillan, Rotello, & Miller, 2004, Perception & Psychophysics)

Single-point sensitivity estimates (d', A', H-F, percent correct, etc):

statistical properties: standard errors and bias in the estimate(Verde, Macmillan, & Rotello, 2006, Perception & Psychophysics)

problems comparing the estimates over conditions that differ in response bias (Rotello, Masson, & Verde, 2008, Perception & Psychophysics)

How to fit a confidence-based ROC with SDT (spreadsheet described by Pazzaglia, Dube, & Rotello, 2013): Download the .zip file to the right.  It contains an Excel sheet with complete instructions.
