According to Aristotle, the most characteristic activity of friendship is “living together” [to suzên]. This paper seeks to understand living together in the light of his famous, foundational claim that humans are social by nature. Based on an interpretation of Nicomachean Ethics 9.9, I explain our need for friends in terms of a more fundamental human need to appreciate one's life as a whole. I then argue that friendship is built into the very structure of human life itself such that human living is living together.  相似文献

Abstract

Although previous research has suggested that regulatory focus may exert considerable impacts on individuals’ subjective well-being (SWB), little research has explored the mechanism for this relation and the potential gender difference. The current study investigated the potential mediating effects of coping styles on the relationship between regulatory focus and three aspects of SWB (indicated by life satisfaction, positive affect, and negative affect) among Chinese adolescents. Total of 2943 Chinese adolescents participated in this cross-sectional survey and completed self-reported questionnaires (Mage = 14.47, SD?=?1.59, 44.50% boys). Hypothesized pathways were tested by structural equation models. Results showed that regulatory foci were significantly associated with SWB. Promotion focus predicted SWB mainly through problem-focused coping, and the mediating effects of emotion-focused coping were also observed; Prevention focus predicted SWB mainly through emotion-focused coping, and the mediating effects of problem-focused coping were observed. Furthermore, relative to boys, the prediction of problem-focused coping on life satisfaction was stronger and the prediction of promotion focus on life satisfaction was weaker for girls. These findings provide a new approach to understand the mechanism for the relationship between regulatory foci and SWB, and indicate the gender differences of this process.  相似文献

The parallel lines illusion change effect (discovered by the authors) was studied: When the plane of a parallel-lines illusion figure intersects obliquely with the line of vision and the figure is rotated, using an imaginary perpendicular line between the parallel lines as the axis, the smaller the intersecting angle, the more the illusory effect decreases, until it disappears. If the illusion figure is rotated and any one of the parallel lines is used as the axis, then the smaller the intersecting angle, the greater the illusory effect. The parallel lines illusion change effect may be applicable to the study of geometric-figure illusions.  相似文献

The ability to discern emotional expressive cues represents an important interpersonal emotional skill at the workplace. In a training study with 123 employee–peer dyads, we examined whether political skill enhances the learning of emotional expressive cues via voices. Controlling for the effects of extraversion and self‐monitoring, it was found that political skill was significantly related to the accurate recognition of emotions via voices after a training session. As predicted, other‐reported political skill was found to be a stronger predictor of such learning than self‐reported political skill. In addition, social astuteness and networking ability were the most predictive of emotional cue learning among the different dimensions of political skill. Implications and limitations are discussed.  相似文献

In functional magnetic resonance imaging (fMRI), the blood oxygenation level dependent (BOLD) signal is often interpreted as a measure of neural activity. However, because the BOLD signal reflects the complex interplay of neural, vascular, and metabolic processes, such an interpretation is not always valid. There is growing evidence that changes in the baseline neurovascular state can result in significant modulations of the BOLD signal that are independent of changes in neural activity. This paper introduces some of the normalization and calibration methods that have been proposed for making the BOLD signal a more accurate reflection of underlying brain activity for human fMRI studies.  相似文献

When asked to judge the membership of typical (e.g., car) vs. atypical (e.g., train) pictures of a category (e.g., vehicle), native English (N = 18) and native Chinese speakers (N = 18) showed distinctive patterns of brain activity despite showing similar behavioral responses. Moreover, these differences were mainly due to the amount and pervasiveness of category information linguistically embedded in the everyday names of the items in the respective languages, with important differences across languages in how pervasive category labels are embedded in item-level terms. Nonetheless, the left inferior frontal gyrus and the bilateral medial frontal gyrus are the most consistent neural correlates of category typicality that persist across languages and linguistic cues. These data together suggest that both cross- and within-language differences in the explicitness of category information have strong effects on the nature of categorization processes performed by the brain.  相似文献

The Flynn effect has been widely researched in Western and European nations, while it has been comparatively understudied in Asian countries. This study examines possible Flynn effects in China from 1985 to 86 and to 2011–12. Results are reported for an IQ increase among 12 year olds on the Full Scale IQ WISC-R (Wechsler Intelligence Scale for Children-Revised) of 6.19 IQ points, a gain on the Performance IQ of 6.55 IQ points, and a gain on the Verbal IQ of 1.91 IQ points.  相似文献

While premature infants have a high need for positive interactions, both infants and their mothers are challenged by the infant‘s biological immaturity. This randomized clinical trial of 198 premature infants born at 29–34 weeks gestation and their mothers examined the impact of the H-HOPE (Hospital to Home: Optimizing the Infant's Environment) intervention on mother–premature infant interaction patterns at 6-weeks corrected age (CA). Mothers had at least 2 social environmental risk factors such as minority status or less than high school education. Mother–infant dyads were randomly assigned to the H-HOPE intervention group or an attention control group. H-HOPE is an integrated intervention that included (1) twice-daily infant stimulation using the ATVV (auditory, tactile, visual, and vestibular-rocking stimulation) and (2) four maternal participatory guidance sessions plus two telephone calls by a nurse-community advocate team. Mother–infant interaction was assessed at 6-weeks CA using the Nursing Child Assessment Satellite Training–Feeding Scale (NCAST, 76 items) and the Dyadic Mutuality Code (DMC, 6-item contingency scale during a 5-min play session). NCAST and DMC scores for the Control and H-HOPE groups were compared using t-tests, chi-square tests and multivariable analysis. Compared with the Control group (n = 76), the H-HOPE group (n = 66) had higher overall NCAST scores and higher maternal Social-Emotional Growth Fostering Subscale scores. The H-HOPE group also had significantly higher scores for the overall infant subscale and the Infant Clarity of Cues Subscale (p < 0.05). H-HOPE dyads were also more likely to have high responsiveness during play as measured by the DMC (67.6% versus 58.1% of controls). After adjustment for significant maternal and infant characteristics, H-HOPE dyads had marginally higher scores during feeding on overall mother–infant interaction (β = 2.03, p = 0.06) and significantly higher scores on the infant subscale (β = 0.75, p = 0.05) when compared to controls. In the adjusted analysis, H-HOPE dyads had increased odds of high versus low mutual responsiveness during play (OR = 2.37, 95% CI = 0.97, 5.80). Intervening with both mother and infant is a promising approach to help premature infants achieve the social interaction patterns essential for optimal development.  相似文献
