Recent criticisms of SDT (see, eg, Balakrishnan, 1999) have identified violations of its assumptions, and researchers have suggested that SDT fundamentally misrepresents perceptual and decision processes. We hypothesize that, instead, these violations of SDT stem from decision noise: the inability to use deterministic response criteria. In order to investigate this hypothesis, we present a simple extension of ... %N 3 %P 465-494 %V 15 %D 2008 %I Springer %L cogprints7714
