The associated nontargets effect: Evidence of nontarget processing at and beyond the level of letter recognition

In four visual search tasks participants were asked to make a target response if either of two targets was present and to make a nontarget response if neither target was present. Some target-absent displays included only nontarget stimuli or features that never occurred in the same displays as targets, whereas other target-absent displays included nontarget stimuli or features that did sometimes occur with targets. Nontarget responses were reliably faster in the former case than in the latter. This “associated nontargets effect” indicates that nontargets are not simply classified as nontargets but in addition are discriminated from one another. Current visual search models may underestimate the degree to which nontargets are processed during search.     

现代医学人文回归的学术性与现实性

以生物-心理-社会医学模式为背景,以哲学和生态审美理论为起点,提出了"医学人文精神"、"医学人文关怀"等概念,在此基础上,分析了医学人文回归的内容及其与医学审美之间的内在联系.从学术性和现实性两个层面,针对我国存在的医学人文缺失的现状,分析了以"三观"(生命观、健康的可持续发展观、科学观)为基础的人文信仰的内容、功能与意义,以及如何从内容与形式辩证统一的审美视角出发,运用美的规律去改善、丰富和提升医学人文关怀的境界.     

Powerful Qualities,Phenomenal Concepts,and the New Challenge to Physicalism

Defenders of the phenomenal concept strategy have to explain how both physical and phenomenal concepts provide a substantive grasp on the nature of their referents, whilst referring to the very same experience. This is the ‘new challenge’ to physicalism. In this paper, I argue that if the physicalist adopts the powerful qualities ontology of properties then a new and powerful version of the phenomenal concept strategy can be developed, which answers the new challenge.     

Do phenomenal concepts misrepresent?

Many contemporary physicalists concede to dualists that conscious subjects have distinctive “phenomenal concepts” of the phenomenal qualities of their experiences. Indeed, they contend that idiosyncratic characteristics of these concepts facilitate responses to influential anti-physicalist arguments. Like some some other critics of this approach, James Tartaglia (2013 Tartaglia, J. (2013). Conceptualizing physical consciousness. Philosophical Psychology, 26(6), 817–838.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) maintains that phenomenal concepts express contents that conflict with physicalism, but as a physicalist, the moral he distinctively draws from this is that phenomenal concepts misrepresent. He contends further that the contemporary physicalists’ account cannot accommodate this feature, and that in consequence, physicalists should abandon phenomenal concepts and return to the identity theory championed by Place and Smart in the 1950s. I respond to Tartaglia by identifying lacunae in his interpretation of contemporary physicalism and arguing that phenomenal concepts as conceived by the contemporary physicalists do not express contents that support either dualist or physicalist metaphysics: they are “metaphysically neutral.”     

Concept Creep: Psychology's Expanding Concepts of Harm and Pathology

Many of psychology's concepts have undergone semantic shifts in recent years. These conceptual changes follow a consistent trend. Concepts that refer to the negative aspects of human experience and behavior have expanded their meanings so that they now encompass a much broader range of phenomena than before. This expansion takes “horizontal” and “vertical” forms: concepts extend outward to capture qualitatively new phenomena and downward to capture quantitatively less extreme phenomena. The concepts of abuse, bullying, trauma, mental disorder, addiction, and prejudice are examined to illustrate these historical changes. In each case, the concept's boundary has stretched and its meaning has dilated. A variety of explanations for this pattern of “concept creep” are considered and its implications are explored. I contend that the expansion primarily reflects an ever-increasing sensitivity to harm, reflecting a liberal moral agenda. Its implications are ambivalent, however. Although conceptual change is inevitable and often well motivated, concept creep runs the risk of pathologizing everyday experience and encouraging a sense of virtuous but impotent victimhood.     

儿童数概念发展的影响因素:表面相似性效应与标签效应

本研究主要考查表面相似性效应和标签效应对60名3～5岁儿童数概念发展的影响。实验通过等量匹配任务和数量比较任务测查儿童数概念的发展情况,其中等量匹配任务和数量比较任务都包括了一致和不一致两种条件以考查表面相似性效应对儿童数概念的影响,并通过给物取数任务、给数取物任务和等量匹配任务与数量比较任务的关系测查儿童使用数字标签的能力对儿童数概念形成与发展的影响。结果表明:(1)4岁和5岁组儿童完成等量匹配任务和数量比较任务的正确率显著高于3岁组儿童;(2)儿童在一致条件下完成等量匹配和数量比较任务的正确率显著高于不一致条件的正确率,表明物体的高表面相似性有利于儿童数概念的形成;(3)擅长使用数字标签的儿童完成等量匹配任务和数量比较任务的次数超过几率水平,使用数字标签有利于儿童数概念的发展。     

具身道德隐喻映射机制的双向性及其问题——基于具身效应“可重复性危机”的思考

具身认知研究虽已取得令人瞩目的进展,但某些具身效应存在可重复性较低的问题。若长期忽视这一问题,将严重损害心理学的科学性,甚至引发一定程度的“可重复性危机”。本文从道德概念清洁隐喻的两大映射方向出发,基于两大实验类型对相关研究中可能存在的问题因素分别展开分析。未来研究应关注更注重社会互动的组织道德,将道德概念具身隐喻研究引申到现实问题中,并借助认知神经科学技术更全面地考察身体经验、情绪体验和认知加工在道德清洁隐喻加工中的作用。     

Frege,Boolos, and Logical Objects

In this paper, the authors discuss Frege's theory of logical objects (extensions, numbers, truth-values) and the recent attempts to rehabilitate it. We show that the eta relation George Boolos deployed on Frege's behalf is similar, if not identical, to the encoding mode of predication that underlies the theory of abstract objects. Whereas Boolos accepted unrestricted Comprehension for Properties and used the eta relation to assert the existence of logical objects under certain highly restricted conditions, the theory of abstract objects uses unrestricted Comprehension for Logical Objects and banishes encoding (eta) formulas from Comprehension for Properties. The relative mathematical and philosophical strengths of the two theories are discussed. Along the way, new results in the theory of abstract objects are described, involving: (a) the theory of extensions, (b) the theory of directions and shapes, and (c) the theory of truth values.     

Natural Numbers and Natural Cardinals as Abstract Objects: A Partial Reconstruction of Frege" s="" grundgesetze="" in="" object="" theory"="

In this paper, the author derives the Dedekind–Peano axioms for number theory from a consistent and general metaphysical theory of abstract objects. The derivation makes no appeal to primitive mathematical notions, implicit definitions, or a principle of infinity. The theorems proved constitute an important subset of the numbered propositions found in Frege"s Grundgesetze. The proofs of the theorems reconstruct Frege"s derivations, with the exception of the claim that every number has a successor, which is derived from a modal axiom that (philosophical) logicians implicitly accept. In the final section of the paper, there is a brief philosophical discussion of how the present theory relates to the work of other philosophers attempting to reconstruct Frege"s conception of numbers and logical objects.
