CCNCS Seminar Details

An introduction to receiver operating characteristic (ROC) curves and their use in memory research

Speaker: Kristina Dietz
Date/Time: Wednesday 24 February 2010, 4.15pm
Location: SB110B, Computing Laboratory, Cornwallis


In this talk, I show how to construct an ROC curve from confidence rating data and then illustrate how information derived from ROCs can be used to compare the fit of different theoretical memory models to a given data set (Chi-square and R-square). Finally, I briefly discuss why superior goodness-of-fit alone should not be misinterpreted as evidence for the assumption that one model is more valid than another. Please note that whilst there will be some equations appearing in this talk, only minimal statistical knowledge is required (normal/Gaussian distribution, z-scores).
