title: Decision noise: An explanation for observed violations of signal detection theory creator: Mueller, S.T. creator: Weidemann, C.T. subject: Cognitive Psychology description: In signal detection theory (SDT), responses are governed by perceptual noise and a flexible decision criterion. 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 ... publisher: Springer date: 2008 type: Journal (Paginated) type: PeerReviewed format: application/pdf identifier: http://cogprints.org/7714/1/MuellerWeidemann2008.pdf identifier: Mueller, S.T. and Weidemann, C.T.
