客体特征统计属性表征机制的特异性

通过两个实验就视觉系统能否像计算平均数那样高效地计算其他统计量的问题进行了探讨。实验—保持—组圆的平均大小不变而改变众数,考察平均数估计是否受众数变化的影响;实验二采用与实验一相同的刺激,直接考察被试估计众数的绩效。结果发现：（1）对平均数的估计不受总体众数变化的影响;（2）对众数的估计往往不如对平均数的估计准确,估计值受平均数变化的影响;（3）在估计众数的任务中,被试成绩受总体极大值的影响。上述结果表明,视觉系统不存在针对众数的自动化加工机制。根据本实验的结果可以进一步推测,视觉系统并非对所有统计量都可做高效加工,而可能存在针对平均数的特异加工机制。     

Enhancement of hardening and thermal resistance of Mg–Sn-based alloys by addition of Cu and Al

Mg–Sn-based alloys are considered as a promising precipitation-hardening system for applications at elevated temperatures, but the hardening effect is not satisfactory owing to sluggish nucleation and rapid coarsening of the major Mg₂Sn lath precipitates. In this study, Cu and Al are added to a Mg–6Sn–1Mn base alloy. The age-hardening response and the microstructures of these modified alloys have been investigated and are compared to that of the base alloy. The additional elements are found to bring several beneficial effects to the alloys for applications at elevated temperatures. Firstly, a eutectic structure consisting of strong intermetallic phases, i.e. Mg₂Cu in the Mg–6Sn–1Mn–2Cu alloy and Al_0.93Cu_1.07Mg in the Mg–6Sn–1Mn–2Cu–2Al alloy, remains stable along the grain boundaries after solution and ageing heat treatments. Secondly, the precipitate density has been increased significantly and the precipitate size has been refined remarkably during ageing at 200?°C. Moreover, the growth of the precipitates is inhibited remarkably during the over-ageing period. Therefore, the age-hardening response and over-ageing resistance are notably improved.     

Nonverbal signals speak up: Association between perceptual nonverbal dominance and emotional intelligence

Emotional communication uses verbal and nonverbal means. In case of conflicting signals, nonverbal information is assumed to have a stronger impact. It is unclear, however, whether perceptual nonverbal dominance varies between individuals and whether it is linked to emotional intelligence. Using audiovisual stimulus material comprising verbal and nonverbal emotional cues that were varied independently, perceptual nonverbal dominance profiles and their relations to emotional intelligence were examined. Nonverbal dominance was found in every participant, ranging from 55 to 100%. Moreover, emotional intelligence, particularly the ability to understand emotions, correlated positively with nonverbal dominance. Furthermore, higher overall emotional intelligence as well as a higher ability to understand emotions were linked to smaller reaction time differences between emotionally incongruent and congruent stimuli. The association between perceptual nonverbal dominance and emotional intelligence, and more specifically the ability to understand emotions, might reflect an adaptive process driven by the experience of higher authenticity in nonverbal cues.     

王充心理学思想新论——兼议中国古代心理学思想史研究方法

本文试图寻求一种新的研究模式,来探索王充的心理学思想。这个模式主要包括两个方法论原则,即:(一)置于思想群系的原则;(二)依据自身逻辑的原则。在这一研究模式引导下,作者发现“唯实唯验”是王充心理学思想的基点。并由此推论出(一)王充心理学思想的本质是“心理即力”;(二)其特征是“心理外显”,而这两者是分别体现在他的人论和心论的思想之中。     

分类中相似性的理论与模型

相似性在分类的原型理论、样例理论、定义理论和理论解释观中都扮演着重要的角色。人们对相似性的研究由来已久,但是它在分类的领域中至今仍是一个相对模糊的概念,这部分地由于揭示相似性的真正机制将涉及到复杂的信息加工过程。本文以分类中的相似性为出发点介绍了近期相似性研究的一些理论与模型并在此基础上对概念和分类领域中的相似性研究进行了分析和总结。     

Personality disorders and personality dimensions in anorexia nervosa

Information on the relationship between anorexia nervosa (AN) and personality disorders (PDs) and dimensions of temperament and character (measured by the Temperament and Character Inventory [TCI; Cloninger, Przybeck Svrakic, & Wetzel, 1994]) is limited. This study examines the predictive validity of the TCI for PD diagnoses assessed by the International Personality Disorder Examination-ICD-10 (IPDE-ICD-10; Loranger, Janca, & Sartorius, 1997) interviews of 46 women with DSM-IV-defined AN. Patients with a PD reported higher levels of harm-avoidance and lower levels of self-directedness than those without a PD. Scores on the TCI were predictive of the number of PD features present, particularly for those PDs in the anankastic, anxious, and dependent groups accounting for 40% to 51% of the variance. Cluster analysis based on scores on the TCI identified a subgroup of patients characterized by low levels of novelty seeking, self-directedness, and cooperativeness and high levels of harm avoidance. This cluster included the majority of those with avoidant, anxious, or dependent PDs. Assessment of particular personality dimensions was able to predict PDs in an anorexic sample. Since normal personality dimensions have greater validity than the categorical PDs, a consideration of normal temperament and character may assist in clinical decisionmaking and considerations concerning treatment.     

Testing the buffering hypothesis: Perceptions of coach support and pre-competitive anxiety among male and female high school athletes

Research suggests that social support moderates or “buffers” the impact of stress on the individual and thus indirectly affects emotional well-being (Cohen and Wills, 1985). The present study sought to extend the “buffering hypothesis” to competitive sport by examining the influence of perceived coach support on competitive state anxiety among young athletes (N = 270). Results from confirmatory factor analyses (CFA) substantiated the validity of the sport-modified Social Provisions Scale (Russell and Cutrona, 1984; Ryska and Yin, 1994). Structural equation modeling analyses revealed a significant support-anxiety effect in the high trait-anxious model only (r =-.27, p .05). The present results suggest that perceived coach support represents an important mediating factor in the sport stress process among highly anxious athletes.     

Effects of trait and situational self-handicapping on competitive anxiety among athletes

Initial evidence suggests that the employment of self-handicapping strategies has a beneficial effect on negative affective states associated with the perceived threat of evaluative contexts (Harris & Snyder, 1986; Leary, 1986). The present study sought to describe the type of self-handicapping behaviors demonstrated by youth athletes (N=238) as well as to assess the stress-buffering role of athlete self-handicapping on indices of competitive state anxiety. Specifically, it was hypothesized that among high trait-handicapping athletes, those who report a greater degree of performance-debilitating obstacles prior to competition would demonstrate lowered cognitive and somatic state anxiety as well as greater state self-confidence than nonhandicapping athletes. However, MANOVA results indicated that both high trait and situational self-handicappers demonstrate elevated state anxiety immediately prior to competition. Results are discussed in relation to the possible role of state anxiety as a salient self-handicapping strategy within competitive sport.     

G.I. Gurdjieff: Some references to love

New developments in the Gurdjieff. teaching (the Work) have raised questions about the authentic line of the teaching. James Moore in his article “Moveable Feasts: The Gurdjieff Work”; (Religion Today 9 (2), 1994: 11–16) argues that, in terms of the dialectic between personal endeavour and supernal grace, Gurdjieff's teaching is based on making effort rather than receiving grace, working rather than being worked upon. The article looks at some references to love made by Gurdjieff and by some of his pupils. It suggests that, although absent from Work teaching in the Gurdjieff Society in London from the 1950s to the 1980s, grace was an element of Gurdjieff s teaching, and that new practices may serve to restore grace.
