Abstract
A method is presented for directly estimating the weights, or 'linear template' used by an observer performing a signal- known-exactly detection task in a two-alternative forced- choice (2-AFC) experiment. The approach generalizes prior work by Ahumada, and Beard and Ahumada, to 2-AFC experiments and correlated image noise, and yields an unbiased estimate of the observer template. The estimation procedure is checked against a known linear detection strategy, and human-observer templates estimated from some preliminary psychophysical experiments are shown.
