The current study examined the effects of institutionalization on the discrimination of facial expressions of emotion in three groups of 42‐month‐old children. One group consisted of children abandoned at birth who were randomly assigned to Care‐as‐Usual (institutional care) following a baseline assessment. Another group consisted of children abandoned at birth who were randomly assigned to high‐quality foster care following a baseline assessment. A third group consisted of never‐institutionalized children who were reared by their biological parents. All children were familiarized to happy, sad, fearful, and neutral facial expressions and tested on their ability to discriminate familiar versus novel facial expressions. Contrary to our prediction, all three groups of children were equally capable of discriminating among the different expressions. Furthermore, in contrast to findings at 13–30 months of age, these same children showed familiarity rather than novelty preferences toward different expressions. There were also asymmetries in children’s discrimination of facial expressions depending on which facial expression served as the familiar versus novel stimulus. Collectively, early institutionalization appears not to impact the development of the ability to discriminate facial expressions of emotion, at least when preferential looking serves as the dependent measure. These findings are discussed in the context of the myriad domains that are affected by early institutionalization. 相似文献

The relations among infant anger reactivity, approach behavior, and frontal electroencephalogram (EEG) asymmetry, and their relations to inhibitory control and behavior problems in early childhood were examined within the context of a longitudinal study of temperament. Two hundred nine infants’ anger expressions to arm restraint were observed at 4 months of age. Infants’ approach behaviors during play with an unpredictable toy and baseline frontal EEG asymmetry were assessed at 9 months of age. Inhibitory control during a Go/No‐Go task and parent report of behavior problems were evaluated at 4 years of age. High anger‐prone infants with left, but not right, frontal EEG asymmetry showed significantly more approach behaviors and less inhibitory control relative to less anger‐prone infants. Although a link between anger proneness in infancy and behavior problems in early childhood was not found, a combination of low approach behaviors and poor inhibitory control was predictive of internalizing behaviors. 相似文献

The presence of service-level-dependent demand has been empirically observed in industry and is well-documented in the literature. How does the implicit contractual existence of such service dependency impact the ordering decisions of upstream suppliers? We conduct three controlled laboratory experiments to study the impact a service-reward mechanism may have on the upstream ordering decisions of those charged with inventory ordering decisions. The multistudy approach provides representations of decision dynamics across a variety of scenarios, from one-shot buys to long-term supply-chain relationships. Our combined empirical results consistently suggest that the service-reward mechanism significantly and systematically elevates order levels and order variability in a manner that increases departure from optimal ordering. This effect is observed even when decision-makers have incentives to maintain a steady ordering pattern with their suppliers. Our findings shed much-needed light on individual ordering responses to, and the associated risks of, service-reward mechanisms. 相似文献

The official rhetoric of welfare states unconditionally pays tribute to older people's right to express dissatisfaction. In practice, users of older services in welfare states may be deprived of their “exit” options and face considerable constraints when it comes to raising their “voices.” For example, when older people in nursing homes would like to lodge a complaint, they may well be referred to the very staff members they depend on in their everyday lives. This article analyzes a national case study in which these contradictory tendencies are especially explicit: formal influence channels for older people in Sweden. Using data from structured interviews with 100 representatives of Swedish municipalities and drawing on Hirschman's (1970) theory on exit and voice, the article analyzes obstacles to older service users' influence in Sweden and develops explanations for these obstacles in terms of social contexts. 相似文献

The discourse of multiculturalism disguises complicated racial dynamics in nations such as Canada. Although white privilege persists, it tends to be mediated through non-white figures who can engender consent from other minority members. These figures have been called model minorities, a role that is well-tailored to celebrated athletes. Athletes who fill the role of model minority represent the ideal immigrant citizen: English-speaking, middle class/bourgeois, disciplined, and hard-working. As such, they serve a disciplinary function for other immigrants by demonstrating how it is they should act and producing a standard against which they are evaluated. The model minority has become a crucial representational figure for multicultural nations like Canada because the political economy of these states requires cheap labour that can be hyper-exploited through the dehumanization of racialization. Drawing on articles in Toronto's most prominent newspapers, I argue that Toronto Blue Jays baseball star Jose Bautista has recently assumed the status of a model minority. I elaborate the functions of the model minority through a reading of Bautista's representation. 相似文献

This article examines the mechanisms linking health to the educational attainment of adolescents. In particular it investigates the role of cognitive/academic achievement and a variety of psychosocial adjustment factors in explaining this relationship. Using data from the National Longitudinal Survey of Youth 1997 cohort (NLSY97), we estimate models of timely high school completion and of post-secondary enrollment using both standard logit estimation and sibling fixed-effects models. We find that, net of sociodemographic background and stable unobserved family characteristics, adolescents who experience worse health are substantially less likely to complete high school by their 20th birthday and to transition to post-secondary education. Cognitive/academic achievement and psychosocial factors appear to explain a large portion of these health-related educational deficits. However adolescent health continues to be significantly associated with these key educational transitions. The findings highlight a potentially important role of health selection processes in generating socioeconomic inequalities in early adolescence to young adulthood. 相似文献

The dominant economic theory of the family explains the negative correlation between family size and child achievement, a
‘quality–quantity trade-off’, through borrowing constraints and credit market failure. This paper presents a model in which
the opportunity cost of time spent with children is increasing, thus creating a trade-off even in economies with perfect credit
markets. While both produce a family size effect, temporal and financial constraints predict different patterns for the trade-off
across levels of parent income. Using data from the National Child Development Study, the trade-off is found even among high-earning
families who presumably do not face credit constraints. Moreover, the trade-off does not grow as parent earnings diminish.
Both of these findings suggest that temporal and not financial constraints explain the quality–quantity trade-off.
