Attractive rivals may undermine the expectation of career advancement and enhance jealousy. An experimental study

This experiment with 119 adult females examined the effect of a rival’s attractiveness on jealousy and career advancement expectations in a simulated work setting where individuals had to compete for a job promotion. We hypothesized that an attractive rival would evoke relatively more jealousy and lower career advancement expectations, especially in individuals high in Intrasexual Competitiveness (ISC). In addition, we examined the moderating effects of characteristics attributed to the rival in terms of popularity, professionalism, and unfriendliness. The results showed that, overall, an attractive rival induced more jealousy and lower career advancement expectations than an unattractive rival. Especially among women who attributed unfriendliness to their rival, the attractiveness of the rival induced higher levels of jealousy and lower career advancement expectations. Among women high in ISC, the rival’s attractiveness induced lower career advancement expectations. It is recommended that managers and human resource officials pay particular attention to how physical attractiveness may interfere with female employees’ professional development, and to the important role of emotions in the workplace.     

The influence of beverage type on aggression in males in the natural setting

Laboratory research has shown that alcohol and aggression are related and that the consumption of distilled as opposed to brewed beverages results in more aggression. A field experiment was conducted in which confederates approached 38 males who had been drinking only brewed or only distilled beverages, and asked them four annoying questions. Responses were recorded, transcribed and rated using a rank ordered scoring method. Results confirmed the prediction of more aggressive responses from the distilled beverage consuming group but findings failed to show a dose effect. The results demonstrate the viability and value of field research in this area and help to elucidate the role of alcohol in aggression.     

情绪和控制幻觉对投资者羊群行为的影响

本研究采用双因素被试间实验具体考察了特定情绪和控制幻觉对于个体投资者羊群行为的影响,结果发现存在显著的主效应和交互作用。愉悦情绪与投资者的追涨羊群行为呈正向关系,恐惧情绪与跟跌羊群行为呈正向关系;控制幻觉与投资者的追涨羊群行为呈正向关系,与跟跌羊群行为呈负向关系;高控制幻觉的投资者在愉悦情绪下倾向于乐观追涨,而低控制幻觉的投资者在恐惧情绪下倾向于悲观跟跌。     

高压氧对老年小鼠记忆力及脑内Ca~(2+)的影响

观察常压（１０１．３ｋＰａ）及高压（２５３．３ｋＰａ）吸氧处理后老年小鼠学习记忆的改善情况,并测定４个主要脑区（皮层,海马,小脑,间脑）突触体内钙离子浓度,结果表明,常压及高压吸氧可明显增强老年小鼠在新异的自我活动能力,并且显著提高记忆保持力,对衰老引起的脑内高下现象具有明显的抑制效应,其中２５３．３ｋＰａ高压氧降钙效果更明显,脑内高钙与记忆衰退密切相关,提示高压氧可能是通过降钙作用而改善脑老化而

Functional visual field in a rapid serial visual presentation task

Dynamic temporal change in the size of functional visual field was measured using a dual task: a peripheral task in which one square in a background pattern of squares was changed in shape to a dot; and a central task involving the rapid serial visual presentation of a sequence of letters (RSVP task). The temporal lag between the occurrences of the dot and the RSVP target was manipulated. University students were asked to detect the dot and to depress a mouse button as quickly as possible while searching for the RSVP target among a sequence of distracter letters. The abrupt change in the shape of a background square in the peripheral task caused a processing deficit in the RSVP task at relative lags from –3 to –1 (255 ms to 85 ms before presentation of the RSVP target), but the encoding and retaining processes involved in identifying the RSVP target did not impair the detection of the peripheral dot. The functional visual field was found to expand while participants were performing the dual task, suggesting that preattentive detection is affected by general attentional activity.     

拼读困难儿童某些认知特征的实验研究

通过两级筛选以验证中国儿童在学习汉语拼音时是否也存在拼读困难,并通过认知心理学方法对拼读困难儿童与同年龄正常儿童进行比较研究,以期深入了解他们的认知整合能力和精细分辨能力。研究结果提示：１．经对１０６０名小学一、二年级学童进行卷面和口试筛选,共发现１２名儿童有汉语拼音拼读困难,约占总样本的１２％。２．拼读困难儿童的某些认知整合能力和精细分辨能力均比正常儿童差,这可能是他们拼读困难的认知心理学基础。     

Dispositional inference from effects of actions: Effects chosen and effects forgone

One hundred and forty-six subjects made comparative judgments as to which of two hypothetical actors they were most confident possessed a choice-related trait, and which was most extreme on that trait dimension. Each actor was portrayed as making a choice from a set of actions; the choice sets varied independently in the number of effects eliminated by the choice and in the number of effects remaining after choice. Results confirmed Jones and Davis' (1965) hypothesis that correspondence would be inversely related to the number of effects remaining after choice. In addition, correspondence was directly related to number of effects eliminated by the choice when effects remaining did not differ. When given both sources of information, subjects preferred to use information from effects remaining.
