A briefly presented visual stimulus followed by darkness seems to persist beyond its physical offset. We are concerned here with the relation between two characteristics of this visible persistence: first, its phenomenological resemblance to the stimulus that spawned it and second, its usefulness as a basis for integrating visual stimuli that are separated in time. We describe two experiments using a task in which two halves of a visual stimulus were presented successively and observers reported how complete the stimulus appeared to be. Stimuli appeared less complete with increases in both the duration of the interval intervening between presentation of the two halves and the duration of the initially presented stimulus half. This data pattern is similar to that obtained in tasks in which spatial integration of two temporally disparate stimuli is necessary for correct responding. On the basis of this similarity, we argue that phenomenological appearance and ability to integrate stimuli over time are two facets of the same perceptual events. We describe a formal model to account for these and other data. 相似文献

The arrangement in which frail older adults from the developed world are cared for in their homes by individuals from the developing world has become increasingly prevalent worldwide. In Israel, this arrangement is termed foreign home care. In this article, the authors first describe the global phenomenon of foreign home care of frail older adults as well as the more local characteristics of this arrangement in Israel. The authors then describe the concept of loneliness. Based on empirical and theoretical knowledge in the field of loneliness, the authors argue that older adults under live-in foreign home care may be particularly prone to feelings of loneliness for several reasons: some that are general to older adults with cognitive or physical disability and others that are specific to this particular caregiving arrangement. The authors conclude by providing ideas for future practice and research on this highly vulnerable group that, to date, has received only minimal research attention. 相似文献

Most anti-paternalists claim that informed and competent self-regarding choices are protected by autonomy, while ill-informed or impaired self-regarding choices are not. Joel Feinberg, among many others, argues that we can in this way distinguish impermissible ??hard?? paternalism from permissible ??soft?? paternalism. I argue that this view confronts two related problems in its treatment of ill-informed decision-makers. First, it faces a dilemma when applied to decision-makers who are responsible for their ignorance: it either permits too much, or else too little, intervention to satisfy its proponents. Second, the most promising rationales in favor of the view ignore the distinction between an agent??s voluntarily bringing about some state of affairs, on the one hand, and an agent??s voluntarily assuming a risk, on the other. I conclude that a decision-maker??s ignorance is irrelevant to the permissibility of intervention on her behalf. If it is permissible to intervene in a given ill-informed choice, it would be permissible to intervene in an otherwise similar but informed choice, at least provided that intervention would produce similar benefits in both cases. This shows that we should sometimes accept straightforwardly paternalistic rationales. 相似文献

Rapid changes in language skills and social competence, both of which are linked to sensitive parenting, characterize early childhood. The present study examines bidirectional associations among mothers' sensitive parenting and children's language skills and social competence from 24 to 36 months in a community sample of 174 families. In addition, this study examines how these developmental pathways vary by child sex. Findings indicate stability across time in sensitive parenting, expressive language skills, and social competence, as well as positive main effects of sensitive parenting on expressive and receptive language skills for girls and boys. We find mixed evidence over time of reciprocal links between social competence and sensitive parenting. Further, boys' receptive language skills at 24 months uniquely contribute to increases in mothers' observed sensitive parenting from 24 to 36 months. These findings highlight the utility of applying transactional frameworks to the study of sex‐based differences in early developmental processes. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

A longitudinal field survey tested the reciprocal effects of acculturation preferences and prejudice among ethnic minorities and majorities. Data were collected at two points in time from 512 members of ethnic minorities and 1143 majority members in Germany, Belgium and England. Path analyses yielded not only the lagged effects of prejudice on acculturation preferences but also the reverse for both majority and minority members. The mutual longitudinal effects between prejudice and desire for culture maintenance were negative, and the mutual effects between prejudice and desire for culture adoption were positive for majority members. The reverse was the case for minority participants. Moreover, the two acculturation dimensions interacted in their effect on prejudice for majority participants but not for minority participants. The effect of desire for culture adoption on prejudice was moderated by perceived intergroup similarity. Theoretical and practical implications of the findings are discussed.

Clinical observations and medical reports indicate that psoriasis has a tremendous impact on patients’ lives, lowering their quality in many important areas. However, the vast majority of research deals only with health-related issues. This study aimed to compare the general quality of life of psoriasis patients and healthy volunteers by examining psychological variables thought to modify the quality of life. 42 patients with psoriasis and 42 healthy volunteers matched for gender, age and education level were tested. Flanagan Quality of Life Scale was used to evaluate general quality of life. Basic hope level was assessed with Basic Hope Inventory. Trait hope was estimated using Trait Hope Scale. Psoriasis Area Severity Index was used to assess the severity of the disease. Psoriasis patients have a significantly lower overall quality of life (p?=?0.05), modified by Physical and Material Well-being (p?=?0.01), Personal Development and Fulfillment (p?=?0.03), and Recreation (p?=?0.04). They also have lower levels of trait hope (p?=?0.04) and its agency component (p?=?0.01). There were moderate, negative significant correlations with basic hope and such components of quality of life as Physical and Material Well-being (p?=?0.03, r?=?? 0.34) and Relations with other People (p?=?0.02, r?=?? 0.35). These results support the hypothesis of a reduced general quality of life and trait hope in psoriatics. Thus, psychological help for people suffering from dermatological disorders might be as important as medical intervention. Basic hope can be treated as a resource in coping with these disorders and trait hope as a resource conducive to well-being. 相似文献

Organisations providing social services in communities of high crime and violence must address staff well-being. The current study surveyed 284 urban community development workers from faith-based organisations in five US cities. The study explored the effects of race and ethnicity on service utilisation and perceived need using binomial logistic regression. Race and ethnicity significantly predicted medical service utilisation, indicating that Caucasian participants were five times more likely and African-American participants were 3.8 times more likely than Latino/a participants to utilise medical services. Race and ethnicity did not predict differences in use of psychological or spiritual services, nor of perceived need for services. Furthermore, volunteer staffs were approximately four times more likely than paid staff to report self-addressing their psychological and spiritual needs rather than utilising services, despite a felt need for support. Barriers to resource utilisation and implications for policies and practices of urban community development organisations are discussed. 相似文献

Different cognitive processes underlying voice identity perception in humans may have precursors in mammals. A perception of vocal signatures may govern individualised interactions in bats, which comprise species living in complex social structures and are nocturnal, fast-moving mammals. This paper investigates to what extent bats recognise, and discriminate between, individual voices and discusses acoustic features relevant for accomplishing these tasks. In spontaneous presentation and habituation–dishabituation experiments, we investigated how Megaderma lyra perceives and evaluates stimuli consisting of contact call series with individual-specific signatures from either social partners or unknown individuals. Spontaneous presentations of contact call stimuli from social partners or unknown individuals elicited strong, but comparable reactions. In the habituation–dishabituation experiments, bats dishabituated significantly to any new stimulus. However, reactions were less pronounced to a novel stimulus from the bat used for habituation than to stimuli from other bats, irrespective of familiarity, which provides evidence for identity discrimination. A model separately assessing the dissimilarity of stimuli in syllable frequencies, syllable durations and inter-call intervals relative to learned memory templates accounted for the behaviour of the bats. With respect to identity recognition, the spontaneous presentation experiments were not conclusive. However, the habituation–dishabituation experiments suggested that the bats recognised voices of social partners as the reaction to a re-habituation stimulus differed after a dishabituation stimulus from a social partner and an unknown bat. 相似文献

ABSTRACTDespite advances in the conceptualisation of facial mimicry, its role in the processing of social information is a matter of debate. In the present study, we investigated the relationship between mimicry and cognitive and emotional empathy. To assess mimicry, facial electromyography was recorded for 70 participants while they completed the Multifaceted Empathy Test, which presents complex context-embedded emotional expressions. As predicted, inter-individual differences in emotional and cognitive empathy were associated with the level of facial mimicry. For positive emotions, the intensity of the mimicry response scaled with the level of state emotional empathy. Mimicry was stronger for the emotional empathy task compared to the cognitive empathy task. The specific empathy condition could be successfully detected from facial muscle activity at the level of single individuals using machine learning techniques. These results support the view that mimicry occurs depending on the social context as a tool to affiliate and it is involved in cognitive as well as emotional empathy. 相似文献
