The current research investigates when and how comparative advertising effectiveness is shaped by social dominance orientation (SDO), that is, the degree to which one desires to maintain the status quo in social hierarchies. We examine these issues with regard to “challenger vs. leader” comparisons that seek to change the relative standing of competitors in a product category by documenting the superiority of challenger brands over market leaders. Findings demonstrate that the resistance to change characterizing high (vs. low) SDO individuals makes them respond (1) less favorably to “challenger vs. leader” comparisons that seek to alter the existing category hierarchy and (2) more favorably to “leader vs. challenger” comparisons that preserve this status quo in the category hierarchy. The theoretical implications of these findings are discussed, as are avenues for future research. 相似文献

We summarize the main findings and conclusions of Warrington's (1975) paper, The Selective Impairment of Semantic memory, a neuropsychological paper that described three cases with degenerative neurological conditions [Warrington, E. K. (1975). The selective impairment of semantic memory. The Quarterly Journal of Experimental Psychology, 27, 635–657]. We consider the developments that have followed from its publication and give a selective overview of the field in 2014. The initial impact of the paper was on neuropsychological investigations of semantic loss followed some 14 years later by the identification of Semantic Dementia (the condition shown by the original cases) as a distinctive form of degenerative disease with unique clinical and pathological characteristics. We discuss the distinction between disorders of semantic storage and refractory semantic access, the evidence for category- and modality-specific impairments of semantics, and the light that has been shed on the structure and organization of semantic memory. Finally we consider the relationship between semantic memory and the skills of reading and writing, phonological processing, and autobiographical memory. 相似文献

The discussion of the relation of levels of reality to categories is important because categories have often been interpreted
as constituting levels of reality. This article explores whether this view is correct, and argues it is not. Categories as
such should not be understood to constitute levels of reality, although particular categories may. The article begins with
a discussion of levels of reality and then turns to specific questions about categories and how they are related to these
levels. 相似文献

DeCaro et al. [DeCaro, M. S., Thomas, R. D., & Beilock, S. L. (2008). Individual differences in category learning: Sometimes less working memory capacity is better than more. Cognition, 107(1), 284-294] explored how individual differences in working memory capacity differentially mediate the learning of distinct category structures. Specifically, their results showed that greater working memory capacity facilitates the learning of novel category structures that are verbalisable and discoverable through logical reasoning processes. Conversely, however, greater working memory was shown to impede the learning of novel category structures thought to be non-verbalisable, inaccessible to conscious reasoning and discoverable only through implicit (procedural) learning of appropriate stimulus-category responses. The present paper calls into question the specific nature of the category learning tasks used, in particular their ability to discriminate between different modes of category learning. 相似文献

This paper examines the influence of context on the processing of category names embedded in sentences. The investigation
focuses on the nature of information available immediately after such a word is heard as well as on the dynamics of adaptation
to context. An on-line method (Cross Modal Lexical Priming) was used to trace how this process unfolds in time. We found that
the information available immediately after a category word is presented is not altered by the sentence context in which the
word is immersed. Rather, the structure of availability of particular exemplars of the category resembles the typicality structure
of a conceptual representation. The adaptation to context occurs later (between 300 and 450 ms after the category word) and
takes the form of a rapid reorganization of the structure rather than a gradual activation of a contextually relevant exemplar.
We claim that such data is best accounted for in a dynamical framework, where a coherent global structure emerges through
locally guided self-organization. 相似文献

We examined whether individual differences in working memory influence the facility with which individuals learn new categories. Participants learned two different types of category structures: rule-based and information-integration. Successful learning of the former category structure is thought to be based on explicit hypothesis testing that relies heavily on working memory. Successful learning of the latter category structure is believed to be driven by procedural learning processes that operate largely outside of conscious control. Consistent with a widespread literature touting the positive benefits of working memory and attentional control, the higher one’s working memory, the fewer trials one took to learn rule-based categories. The opposite occurred for information-integration categories - the lower one’s working memory, the fewer trials one took to learn this category structure. Thus, the positive relation commonly seen between individual differences in working memory and performance can not only be absent, but reversed. As such, a comprehensive understanding of skill learning - and category learning in particular - requires considering the demands of the tasks being performed and the cognitive abilities of the performer. 相似文献

Is Anscombean practical knowledge independent of what the agent actually does on an occasion? Failure to understand Anscombe’s answer to this question is a major obstacle to appreciating the subtlety and plausibility of her view. I argue that Anscombe’s answer is negative, and turns on the nature of mistakes in performance, and reveals a distinctive implicit metaphysics of mind and knowledge, structured by related capacities and exercises of capacities. If my interpretation is correct, then practical knowledge shares features with knowledge-how and knowledge-that, but deserves its own epistemic category. 相似文献

Since its formal definition over sixty years ago, category theory has been increasingly recognized as having a foundational
role in mathematics. It provides the conceptual lens to isolate and characterize the structures with importance and universality
in mathematics. The notion of an adjunction (a pair of adjoint functors) has moved to center-stage as the principal lens.
The central feature of an adjunction is what might be called “determination through universals” based on universal mapping
properties. A recently developed “heteromorphic” theory about adjoints suggests a conceptual structure, albeit abstract and
atemporal, for how new relatively autonomous behavior can emerge within a system obeying certain laws. The focus here is on
applications in the life sciences (e.g., selectionist mechanisms) and human sciences (e.g., the generative grammar view of
language).
