Indiana University Bloomington, USA
J Exp Psychol Learn Mem Cogn 26:1735-43. 2000..Finally, concerns are raised that the all-or-none exemplar processes that form part of Smith and Minda's (2000) elaborated prototype models are implausible and lacking in generality... - Single-system models and interference in category learning: commentary on Waldron and Ashby (2001)Robert M Nosofsky
Department of Psychology, Indiana University, Bloomington 47405, USA
Psychon Bull Rev 9:169-74; discussion 175-80. 2002..In contrast to Waldron and Ashby's argument, we demonstrate that the single-system ALCOVE model (Kruschke, 1992) naturally predicts the result by assuming that its selective-attention learning process is disrupted by the concurrent task... - Comparing exemplar-retrieval and decision-bound models of speeded perceptual classificationR M Nosofsky
Department of Psychology, Indiana University, Bloomington 47405, USA
Percept Psychophys 59:1027-48. 1997..Apparently, a fundamental limitation of the DBM is that it predicts that the fastest RTs in the filtering task should be faster than the fastest RTs in the control task, whereas the opposite pattern was observed in our data... - Exemplar and prototype models revisited: response strategies, selective attention, and stimulus generalizationRobert M Nosofsky
