Misrepresentations of signal detection theory and a model-free approach to human image classification

摘要

Experimental methods and statistics derived from signal detection theory are frequently used to compare two imaging tech- niques, to predict human performance under different parameteriza- tions of an imaging system, and to distinguish variables related to human visual perception from variables related to decision making. We review recent experimental results suggesting that the assump- Tions of signal detection theory are fundamentally unsound.
