Psychological responses to outbreak of severe acute respiratory syndrome: a prospective, multiple time-point study

This study examined anxiety and coping responses to the outbreak of severe acute respiratory syndrome (SARS) in Hong Kong. Trait anxiety, situation-specific coping strategies, and coping flexibility were proposed as predictors of state anxiety during the early phase of the SARS epidemic. Seventy-two Hong Kong undergraduates (31 men, 41 women) participated in a prospective, multiple time-point study. Participants' trait anxiety and coping flexibility had been assessed in an earlier study. Five months later, they reported their anxiety and coping at each of the four time points during the outbreak. Results revealed fluctuations in state anxiety across time points. Results from hierarchical linear modeling showed that trait anxiety as well as the situation-appropriate coping strategies of avoidance and personal hygiene practice accounted for changes in state anxiety.     

An inkblot for attitudes: affect misattribution as implicit measurement

Misattributions people make about their own affective reactions can be used to measure attitudes implicitly. Combining the logic of projective tests with advances in priming research, the affect misattribution procedure (AMP) was sensitive to normatively favorable and unfavorable evaluations (Experiments 1-4), and the misattribution effect was strong at both fast and slow presentation rates (Experiments 3 and 4). Providing further evidence of validity, the AMP was strongly related to individual differences in self-reported political attitudes and voting intentions (Experiment 5). In the socially sensitive domain of racial attitudes, the AMP showed in-group bias for Black and White participants. AMP performance correlated with explicit racial attitudes, a relationship that was moderated by motivations to control prejudice (Experiment 6). Across studies, the task was unaffected by direct warnings to avoid bias. Advantages of the AMP include large effect sizes, high reliability, ease of use, and resistance to correction attempts.     

Shape parameters explain data from spatial transformations: comment on Pearce et al. (2004) and Tommasi & Polli (2004)

In 2 recent studies on rats (J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, see record 2004-12429-006) and chicks (L. Tommasi & C. Polli, see record 2004-15642-007), the animals were trained to search in 1 corner of a rectilinear space. When tested in transformed spaces of different shapes, the animals still showed systematic choices. Both articles rejected the global matching of shape in favor of local matching processes. The present authors show that although matching by shape congruence is unlikely, matching by the shape parameter of the 1st principal axis can explain all the data. Other shape parameters, such as symmetry axes, may do even better. Animals are likely to use some global matching to constrain and guide the use of local cues; such use keeps local matching processes from exploding in complexity.

Scaling relationships in indentation of power-law creep solids using self-similar indenters

We use dimensional analysis to derive scaling relationships for self-similar indenters indenting solids that exhibit power-law creep. We identify the parameter that represents the indentation strain rate. The scaling relationships are applied to several types of indentation creep experiment with constant displacement rate, constant loading rate or constant ratio of loading rate over load. The predictions compare favourably with experimental observations reported in the literature. Finally, a connection is found between creep and 'indentation-size effect' (i.e. changing hardness with indentation depth or load).     

Thermoelectric power in low-density interstitial-free iron-aluminium alloys

Thermoelectric power (TEP) studies on low-density interstitial-free iron-aluminium alloys reveal that the TEP decreases with increase in the aluminium content on account of the introduction of lattice dispersion centres. The TEP coefficients, determined from the Nordheim-Gorter law, for 6.8 and 8.1?wt.% aluminium additions to α-iron are found to be higher than values reported in previous literature for small aluminium additions. The grain size has a very weak effect on the TEP of these alloys.     

学业自我概念发展中的大鱼小池效应

大鱼小池效应(Big-Fish-Little-Pond Effect,BFLPE)是指对于同等能力的学生来说,进入高能力水平学校或班级的学生要比进入低能力水平学校或班级的学生习得更低的学业自我概念的现象.这类似于我国生活格言“宁做鸡头,不做凤尾”的描述.在系统梳理大鱼小池效应的理论与实证研究文献的基础上,对大鱼小池效应的研究现状进行了总结和分析,提出了大鱼小池效应对我国学校能力分组和学生择校现象的启示.未来应进一步加强大鱼小池效应在统计方法、跨文化一致性、具体发生情境、具体发生年龄及外部效度等方面的探讨与验证.     

The effects of valence‐based and discrete emotional states on aesthetic response

There is increasing recognition that consumer aesthetics—the responses of consumers to the aesthetic or appearance aspects of products—has become an important area of marketing in recent years. Consumer aesthetic responses to a product are a source of pleasure for the consumer. Previous research into the aesthetic responses to products has often emphasized exterior factors and visual design, but studies have seldom considered the psychological aesthetic experience of consumers, and in particular their emotional state. This study attempts to bridge this gap by examining the link between consumers’ emotions and their aesthetic response to a product. Thus, the major goal of this study was to determine how valence‐based and discrete emotional states influence choice. In Studies 1 and 2, positive and negative emotions were manipulated to implement two different induction techniques and explore the effect of emotions on participants’ choices in two separate experiments. The results of both experiments confirmed the predictions, indicating that aesthetic responses and purchase intention are functions of emotional valence, such that both are stronger for people in a positive emotional state than for those in a negative emotional state. Study 2 also used a neutral affective state to establish the robustness of this observed effect of incidental affect. The results of Study 3 demonstrate that aesthetic response and purchase intention are not only a function of affect valence, but also are affected by the certainty appraisal associated with specific affective states. This research, therefore, contributes to the literature by offering empirical evidence that incidental affect is a determinant of aesthetic response.
