九鬼周造的偶然哲学与情绪论:和海德格尔哲学的比较

九鬼周造可谓真正与海德格尔的《存在与时间》进行交锋的日本哲学家。九鬼曾出席海氏两年讲座与讨论班,娴熟其哲学,留学归国后,花费毕生精力建构了偶然性的哲学。在此过程中,海氏成为其最大的思想对手。针对海氏可能性的存在论,九鬼提出偶然性的存在论。海氏主张此在的“被抛一筹划”“非本真一本真”“遮蔽一解蔽”等生存论结构,显露出其哲学涵盖了人从非现实的可能状态朝向现实的必然状态发展的向度。九鬼认为这种从可能存在到必然存在的发展过程中缺乏偶然性,正意味着潜在的无限可能性之丧失。支撑海氏的此在生存论结构的正是“畏”这一人的根本情绪。针对畏这个情绪,九鬼提出惊讶的情绪。因为他认为拥抱原始偶然的人,必会不断地涌现惊讶之情,生命也因此有无限的实现可能性。哲学亦须“始于惊讶,终于惊讶”,才能有无限的发展可能性。     

Children’s Responses to Computer‐Synthesized Speech in Educational Media: Gender Consistency and Gender Similarity Effects

This study examines children’s social responses to gender cues in synthesized speech in a computer‐based instruction setting. Eighty 5th‐grade elementary school children were randomly assigned to one of the conditions in a full‐factorial 2 (participant gender) × 2 (voice gender) × 2 (content gender) experiment. Results show that children apply gender‐based social rules to synthesized speech. More specifically, children evaluate synthesized speech more positively, trust the speech more, and learn more effectively when voice gender matches either content gender (consistency attraction) and/or their own gender (similarity attraction). Children’s computer self‐efficacy was a significant covariate for their social responses to synthesized speech. Theoretical and practical implications of the current study for the design of educational media are discussed.     

视觉信息分布调节信息整合策略：来自眼动的证据

以空白单元格定位为实验任务,操纵序列点阵的分布,考察视觉短时记忆与视知觉的信息整合机制。实验一发现任务正确率与点阵1的圆点数呈近似U形关系。实验二发现在拐点前后被试的眼动模式从偏向于注视圆点位置转为偏向于注视空格位置。因此,视觉信息的分布模式调节整合策略,当处于视觉短时记忆中的圆点数在其容量之内时,采用图像—知觉整合策略,反之,则采用转换—比较策略。     

A Dynamical Systems Approach to Manual Tracking Performance

Manual tracking performance was investigated from the perspective of dynamical systems theory. The authors manipulated the type of visual display, the control system dynamics, and the frequency of the sinusoidal input signal to examine couplings with various phases between the visual signal and control movements. Analyses of the system output amplitude ratio and relative phase showed that participants (N = 24) performed poorly with 90° relative phase coupling. All the couplings became less stable as the movement frequency increased. The authors developed an adaptive oscillator model with linear damping to describe the coupled system consisting of the human performer, the visual display, and the control system dynamics. A geometric account of the stability of performance at different relative phases is also presented.     

Self‐confidence,anxiety, and post‐purchase dissonance: a panel study

This study proposes an integrated conceptual model of the antecedents of post‐purchase dissonance. Data were gathered via a two‐stage panel study among consumers who made purchase of technology items. Study results demonstrate that consumer chronic characteristics (i.e., trait anxiety and generalized self‐confidence) not only directly influence post‐purchase dissonance positively and negatively but also are mediated by consumers' temporary feelings (i.e., state anxiety and specific self‐confidence) toward a purchase situation, and then indirectly influence post‐purchase dissonance positively and negatively. Trait anxiety positively influences state anxiety and that generalized self‐confidence and specific self‐confidence negatively influence state anxiety. Furthermore, trait anxiety appears to negatively influence specific self‐confidence, and generalized self‐confidence appears to negatively influence trait anxiety and positively influence specific self‐confidence.     

Amorphization of TiNi induced by high-pressure torsion

Using high-resolution electron microscopy, we investigated the initial stages of high-pressure-torsion-induced crystalline-to-amorphous transformation of TiNi. It is found that the deformation-induced amorphization initiated from dislocation core regions in the interior of grains and from grain boundaries. It is believed that both the energy stored in the dislocations and the energy stored in the grain boundaries contribute significantly to driving the crystalline-to-amorphous transformation.     

PbO compensation in the growth of PbWO4: Y3+ crystals

The light yield of Y³⁺-doped PbWO₄ crystals increases after low-dose-rate irradiation with?γ?rays, and the radiation hardness is sensitive to annealing temperature. In the PWO growth procedure, an excess of PbO in the starting materials is a convenient method of compensating for PbO volatility. The relationship between the excess of PbO and the abnormal radiation behaviour has been investigated. The mechanism of the normal excess of PbO in the growth of PWO: Y³⁺ is discussed.     

Minorities remember more: The effect of social identity salience on group-referent memory

Research on the group-reference effect has confirmed that social identities can affect memory, but few studies have explored the role of identity salience in this effect. Two experiments were designed to fill the gap. In Experiment 1 Tibetan students at one predominantly Han Chinese university showed high ethnic identity salience and better memory for trait adjectives encoded in reference to Tibetans than in reference to Han Chinese. In Experiment 2 Tibetan students at one Tibetan-majority university demonstrated low ethnic identity salience and no differences were found between memory performance under Tibetan-referential processing and Han-referential processing conditions. In comparison, Han participants did not show high ethnic awareness or an ingroup-reference effect in either experiment, due to membership of an ethnic majority (Experiment1) and lack of inter-ethnic contact (Experiment 2). These findings suggest that high salience is a prerequisite for social identities to facilitate memory.     

Minority stress and college persistence attitudes among African American, Asian American, and Latino students: perception of university environment as a mediator

We examined whether perception of university environment mediated the association between minority status stress and college persistence attitudes after controlling for perceived general stress. Participants were 160 Asian American, African American, and Latino students who attended a predominantly White university. Results of a path model analysis showed that university environment was a significant mediator for the association between minority status stress and college persistence attitudes. Additionally, minority status stress was distinct from perceived general stress. Finally, the results from a multiple-group comparison indicated that the magnitude of the mediation effect was invariant across Asian American, African American, and Latino college students, thus supporting the generalizability of the mediation model.
