Oberauer, Klaus – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2006
This article reinvestigates the claim by P. Verhaeghen, J. Cerella, and C. Basak (2004) that the focus of attention in working memory can be expanded from 1 to 4 items through practice. Using a modified version of Verhaeghen et al.'s n-back paradigm, Experiments 1 and 3 show that a signature of a one-item focus, the time cost for switching between…

Soldan, Anja; Mangels, Jennifer A.; Cooper, Lynn A. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2006
This study was designed to differentiate between structural description and bias accounts of performance in the possible/impossible object-decision test. Two event-related potential (ERP) studies examined how the visual system processes structurally possible and impossible objects. Specifically, the authors investigated the effects of object…

Smith, Rebekah E.; Bayen, Ute J. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2006
Event-based prospective memory involves remembering to perform an action in response to a particular future event. Normal younger and older adults performed event-based prospective memory tasks in 2 experiments. The authors applied a formal multinomial processing tree model of prospective memory (Smith & Bayen, 2004) to disentangle age differences…

Rehder, Bob; Hoffman, Aaron B. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2005
An eyetracking study testing D. L. Medin and M. M. Schaffer's (1978) 5-4 category structure was conducted. Over 30 studies have shown that the exemplar-based generalized context model (GCM) usually provides a better quantitative account of 5-4 learning data as compared with the prototype model. However, J. D. Smith and J. P. Minda (2000) argued…
