In this longitudinal study, the authors tested a developmental hypothesis derived from attachment theory and recent empirical findings. Target participants were 78 individuals who have been studied intensively from infancy into their mid-20s. When targets were 20-23 years old, the authors tested the way in which interpersonal experiences at 3 pivotal points in each target's earlier social development--infancy/early childhood, early elementary school, and adolescence--predicted the pattern of positive versus negative emotions experienced with his or her romantic partner. A double-mediation model revealed that targets classified as securely attached at 12 months old were rated as more socially competent during early elementary school by their teachers. Targets' social competence, in turn, forecasted their having more secure relationships with close friends at age 16, which in turn predicted more positive daily emotional experiences in their adult romantic relationships (both self- and partner-reported) and less negative affect in conflict resolution and collaborative tasks with their romantic partners (rated by observers). These results are discussed in terms of attachment theory and how antecedent life experiences may indirectly shape events in current relationships.  相似文献

For a long time, research on motivation and (inter)group behaviour mainly focused on needs and motives, but did not take self‐regulation (i.e., the processes underlying motivated action) into account. Similarly, self‐regulation research concentrated on the regulation of the personal self, but did not study the regulation of the social self. The current article summarizes work applying self‐regulation approaches to intergroup behaviour. Within this approach, it has been shown (a) that the social self is regulated based on the same mechanisms as the personal self, (b) that intergroup contexts impact on group members’ self‐regulation strategies, and (c) that the fit between an individual's self‐regulation strategy and the behavioural options provided by the group impact on group liking and potentially also on the integration of the group into the self‐concept. The relation between current and earlier approaches to motivation in groups and further avenues for research on group‐based self‐regulation are discussed.  相似文献

The near ubiquity of ingroup preference is consistent with the view that it is an automatic consequence of social categorization, possibly a basic foundation of intergroup relations. However, research with adults has demonstrated that automatic ingroup preference is notably absent among less dominant, less advantaged groups, an outcome predicted by System Justification Theory ( Jost & Banaji, 1994 ). How basic is this tendency to justify existing social arrangements? Data from young children are crucial in addressing whether such an opposing orientation is itself a fundamental feature of intergroup social cognition. The developmental data summarized here suggest that knowledge about the relative status of one’s ingroup is absorbed and internalized sufficiently early in life, revealing system‐justifying tendencies by age 5, the earliest age such questions have been examined to date. Across several studies summarized here young children from non‐dominant groups failed to show an implicit ingroup preference, similar to their adult counterparts. We conclude that from an early age intergroup preferences are constrained by knowledge, implicit or explicit, about the relative status differences among groups and may suggest an orientation toward supporting existing social and political structures. The possibility that system‐justifying tendencies may exist in even younger children remains open for future tests.  相似文献

Because of the overly market-oriented way in which technological development is carried out, there is a great amount of hubris in regard to how scientific and technological achievements are used in society. There is a tendency to exaggerate the potential commercial benefits and willfully neglect the social, cultural, and environmental consequences of most, if not all innovations, especially in new fields such as nanotechnology. At the same time, there are very few opportunities, or sites, for ensuring that nanotechnology is used justly and fairly, or for that matter, contribute to alleviating any of the wide variety of injustices that exist in the world. Most of the public authorities responsible for the development and application of science and technology are uninterested and unwilling to “assess” the implications of nanotechnology, and there are few, if any spaces in the broader culture for assessment to take place. Within the various “social movements” that are, in one way or another, concerned with issues of global justice, there is as yet little interest in nanotechnology. By examining the relations between nanotechnology and the emerging movement for global justice this article attempts to understand the enormous gap between the potential for science and technology to do good and the actual ways in science and technology get developed, and what, if anything, might be done to help close the gap in relation to nanotechnology, so that it might better be able to contribute to global justice.  相似文献

Thresholds in various visual and auditory perception tasks have been found to improve markedly with practice at intermediate levels of task difficulty. Recently, however, there have been reports that training with identical stimuli, which, by definition, were impossible to discriminate correctly beyond chance, could induce as much discrimination learning as could training with different stimuli. These surprising findings have been interpreted as evidence that discrimination learning can occur in the absence of perceived differences between stimuli and need not involve the fine-tuning of a discrimination mechanism. Here, we show that these counterintuitive findings of discrimination learning without discrimination can be understood simply by considering the effect of internal noise on sensory representations. Because of such noise, physically identical stimuli are unlikely to be perceived as being strictly identical. We show that, given empirically derived levels of sensory noise, perceived differences evoked by identical stimuli are actually not much smaller than those induced by the physical differences typically used in discrimination-learning experiments. We suggest that findings of discrimination learning with identical stimuli can be explained without implicating any fundamentally new learning mechanism.  相似文献

The ability to differentiate possible events from impossible ones is an invaluable skill when reasoning about claims that transcend the perceptual evidence at hand, yet preschool-aged children do not readily make this differentiation when reasoning about physically extraordinary events [Shtulman, A., &; Carey, S. (2007). Improbable or impossible? How children reason about the possibility of extraordinary claims. Child Development, 78, 1015–1032]. The present study sought to determine whether this failure stems from deficits in domain-specific knowledge or deficits in the domain-general procedure by which possibility judgments are made. Participants (48 children aged 4-9 years olds and 16 adults) were asked to judge the possibility of three types of extraordinary events – physical, psychological, and biological – and to justify their judgments of impossibility. Developmental changes in the ability to differentiate improbable events from impossible events were qualitatively similar across domains. Moreover, participants’ propensity to judge improbable events possible was significantly correlated with the quality of their justifications, both within and across domains. These findings suggest that modal development involves a domain-general change in how modal claims are evaluated.  相似文献

The recollection of particularly salient, surprising or consequential events is often called ‘flashbulb memories’. We tested people's autobiographical memory for details of 11 September 2001 by gathering a large national random sample (N = 678) of people's reports immediately following the attacks, and then by contacting them twice more, in September 2002 and August 2003. Three novel findings emerged. First, memory consistency did not vary as a function of demographic variables such as gender, geographical location, age or education. Second, memory consistency did not vary as a function of whether memory was tested before or after the 1‐year anniversary of the event, suggesting that media coverage associated with the anniversary did not impact memory. Third, the conditional probability of consistent recollection in 2003 given consistent recollection in 2002 was p = .73. In contrast, the conditional probability of consistent recollection in 2003 given inconsistent recollection in 2002 was p = .18. Finally, and in agreement with several prior studies, confidence in memory far exceeded consistency in the long term. Also, those respondents who revealed evidence for consistent flashbulb memory experienced more anxiety in response to the event, and engaged in more covert rehearsal than respondents who did not reveal evidence for consistent flashbulb memory.

Purpose  

The purpose of this study was to investigate whether cognitive style and entrepreneurial drive are important for identifying individuals who have the potential to become successful entrepreneurs, and for discriminating between owner-managers operating in mature and early stages of venture creation and growth.  相似文献
