Many models of spoken word recognition posit the existence of lexical and sublexical representations, with excitatory and inhibitory mechanisms used to affect the activation levels of such representations. Bottom-up evidence provides excitatory input, and inhibition from phonetically similar representations leads to lexical competition. In such a system, long words should produce stronger lexical activation than short words, for 2 reasons: Long words provide more bottom-up evidence than short words, and short words are subject to greater inhibition due to the existence of more similar words. Four experiments provide evidence for this view. In addition, reaction-time-based partitioning of the data shows that long words generate greater activation that is available both earlier and for a longer time than is the case for short words. As a result, lexical influences on phoneme identification are extremely robust for long words but are quite fragile and condition-dependent for short words. Models of word recognition must consider words of all lengths to capture the true dynamics of lexical activation. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Research suggests that schizotypal personality disorder (SPD) is a part of the spectrum of schizophrenia-related illnesses. This article hypothesizes that a deficit in the representation and maintenance of context is a core cognitive disturbance in schizophrenia and that SPD individuals should demonstrate context-processing deficits. To test this hypothesis, the authors administered 3 versions of their AX-CPT task, designed to assess context processing, to 35 healthy controls and 26 individuals with DSM-IV SPD. They also administered working memory and selective attention tasks. SPD individuals displayed context representation deficits similar to those found in schizophrenia but did not show the same additional deficits in context maintenance. Context processing was strongly associated with working memory and selective attention performance in the SPD individuals. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

The last dozen years have produced almost 50 English language articles on the synthesis of separation systems [1]. Most work has considered separating a single relatively ideal mixture into sharply split, usually pure-component products using systems of single-feed, two-product distillation columns. Of late, the work has considered heat-integrating these columns to reduce energy consumption. Present research will very likely produce valuable results for nonsharp separations.Earlier approaches developed both algorithmic- and heuristic-based tree search algorithms for discovering the better systems of non-heat-integrated columns. New results permit the design of heat-integrated systems.The paper highlights the above developments. 相似文献

The article proposes a theoretical framework in which moral reasoning about mediated crime and punishment is defined and combined with existing, affect-driven entertainment theory to yield an integrated theory of enjoyment. The authors analyze how crime dramas serve as statements about justice and then address how moral deliberation about the propriety of those statements impacts enjoyment. The authors report research findings to support the analysis of cognitive processing during crime dramas distinct from affective processing. The article also suggests future means by which the integrated theory of enjoyment can be examined. 相似文献

Applying information systems strategic planning (ISSP) theory to a practical planning effort is not a straightforward endeavor, and the penalties of a misapplied planning exercise are high. IS managers do not need another conceptual framework for ISSP as much as they need a practical point of view on driving the planning effort to produce tangible, high-quality results. 相似文献

This paper presents the results of tensile tests on viscoelastic films of two materials: a 100 pen bitumen and a commercial corn syrup. Experiments were performed using double-cantilever beam specimens, and butt-joint specimens, for a wide range of testing conditions. Failure by brittle fracture, voiding, and various viscous flow mechanisms was observed. The results are presented in the form of maps and are discussed in conjunction with appropriate mathematical models. 相似文献

Remote center‐of‐compliance devices were developed to facilitate insertion for assembly operations. An analysis using screw theory yields a more accurate model to better characterize the interesting properties of remote compliance. For design purposes, the remote center location and stiffnesses are presented as nondimensional ratios that are only functions of geometrical properties and Poisson's ratio. Important design results are (i) the high sensitivity of the center location and (ii) the inverse relationship between linear and angular lateral stiffnesses. © 2003 Wiley Periodicals, Inc. 相似文献
