Archival studies of within-family prosocial behavior (Judge & Hrdy, 1992; Smith, Kish, & Crawford, 1987) have shown that inheritance patterns support Hamilton’s (1964) theory of inclusive fitness, such that people will more of their estates to relatives of closer genetic relatedness. In a survey-based simulation of these studies, students allocated one of three lotteries to their blood relatives. As expected, participants allocated greater proportions of their lotteries to relatives of greater genetic relatedness. This effect became stronger with decreasing lottery amounts. Relatives of certain relatedness were favored over relatives of uncertain relatedness (via paternal uncertainty), and this effect was stronger among those with less money to allocate. Male participants tended to favor their young female relatives over their young male relatives when given the smallest lottery, but this sex preference reversed when male participants were given the largest lottery. In general, scarcer resources led to more evolutionarily conservative investment strategies.  相似文献

Cognitive science and religion provides perspectives on human cognition and spirituality. Emergent systems theory captures the subatomic, physical, biological, psychological, cultural, and transcendent relationships that constitute the human person. C. S. Peirce's metaphysical categories and existential graphs enrich traditional cognitive science modeling tools to capture emergent phenomena. From this richer perspective, one can reinterpret the traditional doctrine of soul as form of the body in terms of information as the constellation of constitutive relationships that enables real possibility.  相似文献

This article explores the extent to which the I-You relation should be applied to domains other than the human and the divine focusing particularly on artifacts and technology. Drawing first on the work of Martin Buber, Gabriel Marcel, and Martin Heidegger, I contend that the I-You tradition has maintained I-You relations with objects are possible even when these same figures level strong critiques of the I-It relation. I extend these discussions and argue that some kind of You-speaking for artifacts is needed to combat rampant consumption and reduction of the world to pure utility. But, I equally suggest that there are limitations to applying the I-You relation to artifacts precisely when doing so keeps us from having genuine relationships with other people as outlined by psychologist Sherry Turkle. Finally, I outline how this proposal impacts the doctrine of creation. In sum, it expands our intuitions of what is included in that doctrine creation.  相似文献

A patient with sarcoidosis involving predominantly the hypothalamus and fornices was evaluated for dementia. He showed a relative sparing of fund of knowledge and orientation. Memory skills, particularly short-term memory, were severely impaired. Behavioral changes included apathy and a lack of spontaneity. Insight was relatively preserved. The pattern of his deficits showed some similarities to the pattern reported in patients with Huntington's disease and was different from that described in Alzheimer's disease. The dementia caused by subcortical pathology may differ in important respects from that caused by diffuse cortical dysfunction.  相似文献

Whether “psychometric” and “Piagetian” kinds of intelligence, as measured by instruments designed to measure these constructs, are the same or different is regarded as a question of whether they have the same or different courses of development with age. While factor analysis may not be fully adequate for investigation of this question, use of this technique with variables reflecting chronological age variation must involve elimination of the age effect in order to assess relations among the constructs measured. Humphreys and Parsons (1979) were justified in partialing out age in their reanalysis of a study by Stephens, McLaughlin, Miller, and Glass (1972), to show that the two constructs are highly correlated and possibly identical in the sample studied. Reanalyses of studies by DeVries and Kohlberg (1977) and by DeVries (1974) yield somewhat conflicting results on the identity between psychometric and Piagetian intelligences. The former study does not yield a convincing separation between them, whereas the latter suggests that they can be distinguished, though substantially correlated and both loaded with a general factor. Problems in further investigating the issue are discussed.  相似文献

Interaction quality and child temperament predict early and later child development. Research hints at transactional interrelations of both aspects but lacks adequate data to examine this assumption. Maternal psychosocial resources are suspected moderators in this context but rarely taken into account. Drawing on data of the German National Educational Panel Study we conducted a cross-lagged panel analysis on the longitudinal interplay of maternal interaction quality and children's negative affectivity at 6–8, 16–18, and 25–27 months and compared mothers with and without accumulated strains. Both variables showed moderate to high structural and rank order stability over time and low but increasing connections. In the case of accumulated stress factors, interaction quality is clearly impaired and high negative affectivity acts as an additional burden while low negative affectivity helps strained mothers to maintain higher interaction quality but only in the first year of life.  相似文献

Based on the risk homeostasis theory, the aim of this study was to assess acceptable risk, measured by personality factors, and risk perception, measured by physiological arousal, as predictors of risky behavior in young adult pedestrians, as well as to assess for gender differences. Eighty-two young adults, aged 18–30, completed self-report measures about risky pedestrian behaviors and these personality traits: impulsiveness, conscientiousness and openness to experience. Sixty-four of these participants then took part in an experimental task designed to assess their perception of the level of risk in situations involving different interactions between cars and pedestrians. Risk perception was assessed by these physiological responses: heart rate, skin conductance level, and skin conductance response. Results showed that risky behavior had significant correlations with impulsiveness, conscientiousness, and skin conductance level. Gender differences also emerged in risky behavior, impulsiveness, conscientiousness, and skin conductance level. Finally, a structural equation model showed that impulsiveness, conscientiousness and the difference in skin conductance level between risky and neutral situations predicted risky pedestrian behaviors, and explained 23.6% of the its variance, after controlling the effect of gender. Implications for evaluation, prevention, and intervention for risky pedestrian behaviors are discussed.  相似文献

We draw on the recently developed communicative ecology model of successful aging (CEMSA) to examine how adults communicate about aging and how these communication patterns relate to experiences of successful aging. Using latent class analysis across 2 datasets collected in New Zealand and the United States, we identify 3 distinct classes of agers (disengaged, engaged, and bantering) defined by different profiles of communication behavior. Across samples, an engaged profile was generally associated with the most positive experiences of aging, whereas a disengaged profile was associated with the least positive experiences, although these differences were surprisingly small. Our results highlight the diverse ways in which individuals communicatively engage with the process of aging and experience aging as positive and successful.  相似文献

Technologies for human germ-line modification may soon enable humanity to create new types of human beings. Decisions about use of this power entail an unprecedented combination of difficulties: the stakes are immense, the unknowns are daunting, and moral principles are called into question. Evolved morality is not a sure basis for these decisions, both because of its inherent imperfections and because genetic engineering could eventually change humans’ innate cognitive mechanisms. Nevertheless, consensus is needed on moral values relevant to germ-line modification. These values could be based on characteristics of human beings that would remain constant regardless of revised genomes.  相似文献

出勤主义行为是指在生病时依然坚持工作的行为。工作场所的出勤主义行为不仅危害员工的个人健康,还会给企业带来额外的支出。近年来,出勤主义行为逐渐引起管理者的重视,并得到越来越多管理学和心理学研究者的关注。总结以往研究,对出勤主义行为的概念界定和测量方法进行了概述,从个人因素、工作相关因素、组织层面因素和团队层面因素四个方面探讨了出勤主义行为的影响因素,并总结了出勤主义行为对个人健康、工作方面和组织层面的影响。最后,对出勤主义行为未来的研究方向进行了展望。  相似文献
