Fitting a psychometric function to price judgments: an analysis of consumers' discounted prices

We examined a psychometric function of price judgment, comparing the mental ruler model, which predicted inverted S-shaped psychometric function, with a power function. Subjects, 102 citizens living in Japan, were asked to rate satisfaction with specified discounted prices. Analysis indicated that predictions of the mental ruler model gave a better fit than those of the power function.

Achieving Subjective Well-Being Around the World: The Moderating Influence of Gender,Age and National Goals for Socializing Children

We propose that one’s subjective well-being (SWB) arises from the satisfaction of one’s basic needs, but that the importance of attaining specific needs will vary according to one’s gender, age, and national culture. We argue that the role of one’s national-cultural background in that process can best be unpackaged in terms of the emphasis of a nation’s citizens on the goals for socializing children, namely, self-directedness versus other-directedness and civility versus practicality. Accordingly, we analyzed the responses of 65,025 persons across 50 nations to questions on the World Values Survey about their perceived state of health, financial satisfaction, trust of in-group members, and sense of personal control over events. Using HLM analysis, we showed that all four factors were significant predictors of SWB pan-nationally, but that the linkages of financial satisfaction and trust of in-group members to SWB were moderated by a nation’s self-directedness and civility; those of financial satisfaction and health were moderated by age. These results indicate that the socialization emphases characterizing one’s national culture operate to make some of the key contributors to one’s SWB more or less predictive. Cross-national studies are thereby vindicated in their capacity to reveal nation-specific formulas for psychological processes leading to SWB.     

Eye-contact perception in schizophrenia: relationship with symptoms and socioemotional functioning

Accurately perceiving self-referential social signals, particularly eye contact, is critical to social adaptation. Schizophrenia is often accompanied by deficits in social cognition, but it is unclear whether this includes gaze discrimination deficits. This study investigated whether eye-contact perception is preserved or impaired and if it is related to symptoms and broader socioemotional functioning in schizophrenia. Twenty-six participants with schizophrenia (SCZ) and 23 healthy controls (HC) made eye-contact judgments for faces in varying gaze direction (from averted to direct in ten 10% increments), head orientation (forward, 30° averted), and emotion (neutral, fearful). Psychophysical analyses for forward faces showed that SCZ began endorsing eye contact with weaker eye-contact signal and their eye-contact perception was less of a dichotomous function, as compared with HC. SCZ were more likely than HC to endorse eye contact when gaze was ambiguous, and this overperception of eye contact was modulated by head orientation and emotion. Overperception of eye contact was associated with more severe negative symptoms. Decreased categorical gaze perception explained variance of socioemotional deficits in schizophrenia after taking basic neurocognition into consideration, suggesting the relationship was not solely due to a general deficit problem. These results were discussed in relation to the nature of categorical gaze perception and its significance to clinical and functional presentations of schizophrenia.     

Residential mobility, self-concept, and positive affect in social interactions

The present research examined (a) the link between personal history of residential mobility and the self-concept and (b) the implications of such a link for positive affect in social interactions. Study 1 showed that the personal self was more central to the self-definition of frequent movers than to that of nonmovers, whereas the collective self was more central to the self-definition of nonmovers than to that of frequent movers. Results from a laboratory and a 2-week event sampling study (Studies 2 and 3) demonstrated that frequent movers felt happier when an interaction partner accurately perceived their personal selves, whereas nonmovers felt happier when a partner accurately perceived their collective selves. These findings present the first direct evidence on how personal history of residential mobility is linked to important individual differences in the self and positive affect in social interactions.     

不对称伦理：境遇危机下医患诚信的一种解读

医患诚信是一种不对称伦理形态,主体责任和缺失补偿不对等构成其伦理特质,崇敬生命承载其价值本质,原则倒置表征其正义诉求.我国医患诚信深陷境遇危机,人们对医患诚信的读误致使医患冲突进一步加剧.从伦理视域直面医患矛盾,重新解读深陷境遇危机的医患诚信,对于重建医患诚信具有重要的理论和现实意义.     

贫困地区初中生学业自我效能、内部动机与学业成绩的关系研究

对贫困地区初中生学业自我效能、内部动机与学业成绩之间关系的测量研究表明：不同学业成绩组学生在自我效能、成功动机、促进性紧张、期望水平和自己责任性方面差异显著;学业自我效能与内部动机诸因素有密切关系、共同构成影响学业成绩的内在因素;对学业成绩正向预测作用最强的是自我效能,其次是促进性紧张和成功交往动机。     

珠心算训练儿童加法心算的ERP早成分研究

采用事件相关电位(ERP)的方法,对32名儿童进行了双位数加法心算实验,探讨了珠心算训练方式对儿童加法心算加工早期感知觉的影响。研究结果表明,与非珠心算训练儿童相比,在加法心算过程的早期阶段,珠心算训练儿童枕部P1、额中央区的N1波幅增大,而颞枕区N170以及额中央区P2波幅减小。本研究结果发现珠心算训练对儿童心算过程的早期感知有显著影响。
