Characteristic analysis

Abstract
Group Operating Characteristic (GOC) analysis can be used to reduce the
effects of unique noise on data from psychophysical experiments on hearing.
Unique noise can come from physiological sources such as heartbeat and breathing
and from other internal sources such as criterion variability, inattention, and
faulty memory. The theory of GOC analysis is described and applied to the
results of frequency discrimination experiments with human, pigeon, and
simulated observers. The method yields relatively unattenuated measures of
sensitivity, recovers Receiver Operating Characteristic curves from noisy choice
data, and estimates the relative magnitudes of unique and common noise.
