风险容忍对飞行员驾驶安全行为的影响：风险知觉和危险态度的作用

采用问卷法调查了257名中国航线飞行教员、机长和副驾驶, 通过结构方程模型和层次回归分析探讨了风险容忍对飞行员驾驶安全行为的影响, 以及在这一影响过程中风险知觉和危险态度所发挥的作用。结果发现：(1)风险容忍对飞行员驾驶安全行为具有显著的负向影响, 高风险容忍飞行员的驾驶安全行为水平显著低于低风险容忍飞行员; (2)风险知觉在风险容忍对飞行员驾驶安全行为的影响过程中发挥了调节作用, 即高水平的风险知觉削弱了风险容忍对飞行员驾驶安全行为的负向影响。(3)危险态度在风险容忍对飞行员驾驶安全行为的影响过程中发挥了完全中介作用, 且这种中介作用的实现又受到风险知觉的调节, 即危险态度对飞行员驾驶安全行为的影响是有调节的中介效应。     

心理危机脆弱性量表的编制及信效度检验

在文献分析和专家评定的基础上,通过访谈和问卷调查,编制了初始的心理危机脆弱性问卷。通过项目分析、探索性因素分析和验证性因素分析对初始问卷进行修订,最终形成的正式量表包含四个维度：挑战力、应对力、支持力和恢复力。结果表明,心理危机脆弱性量表具有较高的内部一致性信度、重测信度以及较好的内容效度、结构效度和效标效度。该量表的心理测量学指标良好,可以作为我国成年人心理危机脆弱性的测量工具。     

What are you looking at? Acuity for triadic eye gaze

The authors measured observers' ability to determine direction of gaze toward an object in space. In Experiment 1, they determined the difference threshold for determining whether a live "looker" was looking to the left or right of a target point. Acuity for eye direction was quite high (approximately 30 s arc). Viewing the movement of the looker's eyes did not improve acuity. When one of the looker's eyes was occluded, the observers' acuity was disrupted and their point of subjective equality was shifted away from the exposed eye. Experiment 2 was a replication of Experiment 1, but digitized gaze displays were used. The results of Experiment 3 showed that the acuity for direction of gaze depended on the position of the looker's target. Overall, the results indicated that humans are highly sensitive to gaze direction and that information from both eyes is used to determine direction of regard.

青少年早期内化问题的稳定性及其与母亲教养的关系

通过对502名11岁城市青少年为期2年的追踪调查,考察了青少年早期内化问题发展的稳定性及母亲教养对1年后青少年内化问题的预测.结果发现:(1)青少年早期的内化问题具有较高的稳定性,与男青少年相比,女青少年保持较高的内化问题水平;(2)母亲控制惩罚教养可以正向预测1年后男青少年的内化问题,母亲温情引导可以负向预测女青少年的内化问题.青少年先前的内化问题对母亲教养与其1年后内化问题之间关系的调节作用存在性别差异:对于先前内化问题水平较高的男青少年而言,母亲较高的温情引导和控制惩罚教养正向预测其1年后的内化问题;对于先前内化问题水平较高的女青少年而言,母亲较多的温情引导则负向预测其1年后的内化问题.     

Organizational Tenure Diversity as Predictors of Combat Performance in ROK Army

Drawing on the upper-echelons theory and diversity issues, this study examines the relationships between top management team (TMT) organizational tenure, tenure diversity, and combat performance. The study is based on of Korea Combat Training Center (KCTC) that is designed for training and evaluation of the battalion combat power. Findings indicate that battalions with higher levels of TMT tenure have a positive effect on combat performance. Tenure diversity of TMT has a negative effect on combat performance. In addition, results showed that the negative relationships between tenure diversity of TMT and combat performance are attenuated by commander’s shared experience with other TMT members.     

Personalized persuasion: tailoring persuasive appeals to recipients' personality traits

Persuasive messages are more effective when they are custom-tailored to reflect the interests and concerns of the intended audience. Much of the message-framing literature has focused on the advantages of using either gain or loss frames, depending on the motivational orientation of the target group. In the current study, we extended this research to examine whether a persuasive appeal's effectiveness can be increased by aligning the message framing with the recipient's personality profile. For a single product, we constructed five advertisements, each designed to target one of the five major trait domains of human personality. In a sample of 324 survey respondents, advertisements were evaluated more positively the more they cohered with participants' dispositional motives. These results suggest that adapting persuasive messages to the personality traits of the target audience can be an effective way of increasing the messages' impact, and highlight the potential value of personality-based communication strategies.

Semantic size does not matter: "bigger" words are not recognized faster

Sereno, O'Donnell, and Sereno (2009) reported that words are recognized faster in a lexical decision task when their referents are physically large than when they are small, suggesting that "semantic size" might be an important variable that should be considered in visual word recognition research and modelling. We sought to replicate their size effect, but failed to find a significant latency advantage in lexical decision for "big" words (cf. "small" words), even though we used the same word stimuli as Sereno et al. and had almost three times as many subjects. We also examined existing data from visual word recognition megastudies (e.g., English Lexicon Project) and found that semantic size is not a significant predictor of lexical decision performance after controlling for the standard lexical variables. In summary, the null results from our lab experiment--despite a much larger subject sample size than Sereno et al.--converged with our analysis of megastudy lexical decision performance, leading us to conclude that semantic size does not matter for word recognition. Discussion focuses on why semantic size (unlike some other semantic variables) is unlikely to play a role in lexical decision.
