Three experiments were designed to determine the accuracy and latency with which right-handed Chinese university students (12 females and 12 males) recognized Chinese characters in the left and right visual half-fields (VHFs). The experiments varied in the "depth" of processing required. Experiment 1 was a lexical decision task in which the configuration of the stimulus (a real Chinese character or the mirror image of a real character) determined whether the grapheme was an actual character. Experiment 2 required phonological processing; i.e., subjects had to decide whether a character (or a foil) matched the sound of an orally presented Chinese character. Experiment 3 required semantic processing; i.e., subjects had to decide if a character (or a foil) belonged to a particular semantic category. In each experiment, single characters were presented unilaterally for 150 msec. There was a significant right VHF superiority for accuracy scores for Experiments 2 and 3 but not for Experiment 1. None of the experiments yielded significant visual asymmetries in reaction time. The results do not support previous claims of orthography-specific laterality, but instead show that laterality effects for morphemic stimuli vary with the orthographic, phonological, and semantic processing demands of the task. 相似文献

Power differences are thought to interfere with superiors' interaction with subordinates. However, it is also argued that superiors with considerable power are most supportive of their subordinates. To explore these opposing positions, 90 undergraduates became managers with either high or low power who believed their goals were cooperatively, individualistically, or competitively related to their subordinate. Results support the hypothesis that social context affects how superiors use their power to interact with subordinates. High- and low-power superiors in cooperation had positive expectations, interacted constructively, restated the task, responded to requests for assistance, and developed a positive relationship compared to high- and low-power superiors in individualistic and competitive situations. In addition, only the high-power superiors in cooperation used their expertise to give direct aid to the subordinate. Results indicate that in cooperation superiors are likely to use their power constructively; however, in competitive and individualistic contexts, superiors are apt to fail to use their resources to facilitate subordinate performance. Results were also interpreted as suggesting that it is not so much the extent of superiors' power but the social context that affects their use of power and interaction with subordinates. 相似文献

Answering a question regarding a stimulus word can cause incidental encoding of the word itself. The thoroughness of the encoding depends in part upon what question is answered. For example, saying whether a word describes oneself causes a particularly high degree of incidental encoding. The study reported here investigated several variables that have been proposed as mediators of that effect. As in previous research, subjects completed an incidental-encoding and recall procedure. They then rated (a) the quality and degree of affect that they would experience if each stimulus word were to be applied to them, (b) the importance to them of the behavioral/psychological dimension implied by the stimulus word, and (c) the degree to which they saw themselves as distinctive on that dimension. As in previous studies, deciding whether a word described the self increased the likelihood of subsequent recall. There also was a highly significant interaction such that words judged to be applicable to self were recalled better than those judged not to be applicable. There was no evidence, however, of a mediational role for any other variable studied. Discussion centers on theoretical implications of the data. 相似文献

Multidimensional scaling procedures were used to investigate developmental changes in the ability to process previously unfamiliar faces. Eighty male subjects, aged 7, 9, 12, or adult, rated the similarity of pairs of faces. The faces were presented to subjects in either the upright or the inverted orientation. Multidimensional scaling analyses suggest that subjects of all ages use similar information in judging the similarity of faces. However, for upright faces, individual subjects under age 10 seem to use fewer features at a time. The results argue against a qualitative shift in face processing at age 10, and suggest that the improvement in face recognition ability noted at this age is due at least in part to an increased ability to consider more features simultaneously. 相似文献

Recent studies have made great strides looking at the implications that the human need for ontological security has for politics and International Relations. However, less attention has been paid to how actors might target this need. While Steele and Mattern both examine the possible manipulation of subjectivity, this article turns to the concept of information warfare (IW) to broaden the view of how, and to what end, this is pursued. Congruently, by elaborating upon how the digitalization of society has increased the potential to influence and manipulate cognition and emotion, OS strengthens current literature on IW. It argues that by covertly perverting the information landscape, IW can alter how events are connected to national narratives, influencing policy by making certain options appear more/less shameful, or it can unravel the bonds of society by polarizing domestic narrative debates, purposely sowing ontological insecurity. This provides a firmer understanding of the strategic implications interference can have generally and of Russia's interference into the 2016 U.S. election specifically. Therefore, by viewing facets of IW as part of a range of tactics employed to manipulate/undermine subjectivity, a more nuanced understanding of interstate relations subsequently emerges. 相似文献

A commutative BCK-algebra with the relative cancellation property is a commutative BCK-algebra (X;*,0) which satisfies the condition: if a ≤ x, a ≤ y and x * a = y * a, then x = y. Such BCK-algebras form a variety, and the category of these BCK-algebras is categorically equivalent to the category of
Abelian ℓ-groups whose objects are pairs (G, G
0), where G is an Abelian ℓ-group, G
0 is a subset of the positive cone generating G
+ such that if u, v ∈ G
0, then 0 ∨ (u - v) ∈ G
0, and morphisms are ℓ-group homomorphisms h: (G, G
0) → (G′,G′0) with f(G
0) ⫅ G′0. Our methods in particular cases give known categorical equivalences of Cornish for conical BCK-algebras and of Mundici for
bounded commutative BCK-algebras (= MV-algebras).

In the United States, judicialrulings that unrealistically addressed the complexityof cases and demonstrated limited understanding ofprinciples, helped to create a legal quagmire whichlegislatures had to confront. Moreover, thelegislative response was often slow and inadequate interms of both the scope and clarity of the laws. However, since the 1970s, progress has been made onmany fronts, particularly in regard to advancedirectives dealing with end-of-life decisions. Thedebate over physician-assisted suicide has spawned arepetition of moral and legal arguments. Thoseagainst legalization have failed to make a realisticappraisal of the dilemmas facing patients and theirfamilies in an age of technological medicine deliveredin the context of the marketplace. The underlyingproblem is a system in dire need of reform that willno longer treat health care as a commodity of themarketplace and provide universal health care. Terminal care as an integral part of health care willsubstantially benefit from such reforms because amajor obstacle to comprehensive palliative care is thecondition of the present system. 相似文献

This article considers the sort of diversity in perspective appropriate for a presidential commission on bioethics, and by implication, high-level governmental commissions on ethics more generally. It takes as its point of comparison the respective reports on human cloning produced by the National Bioethics Advisory Commission, appointed by President Bill Clinton, and George W. Bush's President's Council on Bioethics, under the leadership of its original chair, Leon Kass. I argue that the Clinton Commission Report exemplifies forensic diversity (the type of diversity between contesting parties in a legal case), while the Kass Council Report exemplifies academic diversity (the diversity found in a medieval disputatio). Drawing upon Thomas Aquinas, I argue that the type of diversity most appropriate for such advisory bodies is deliberative diversity, which facilitates the President's process of taking counsel. After considering their respective charges, I suggest that neither the Clinton Commission nor the Kass Council possessed an adequate degree of deliberative diversity for their respective tasks. 相似文献
