Detecting a target letter in briefly presented arrays: A confidence rating analysis in terms of a weighted additive effects model

Abstract

A visual experiment is reported in which Os rated their "confidence" that briefly presented four-letter arrays contained one or more target-letter Fs. Their responses are interpreted as the product of a weighted "additive" combination of partial or "noisy" subjective representations of the four letters in each array. © 1974 Psychonomic Society, Inc.
