Prematurity stereotyping: effects on mother-infant interaction   总被引：1，自引：0，他引：1

The possibility that the self-fulfilling prophecy process can adversely affect the caregiving environment of premature infants was explored in this study. A portion of this process was investigated experimentally by assessing cognitive and behavioral reactions of 27 mothers to unfamiliar full-term infants who were labeled either full-term or premature. Infants who were described as premature were touched less and given a more immature toy to play with, were rated as smaller, finer-featured, and less cute, and were liked less than infants who were labeled full-term. In turn, infants labeled premature were less active during the interaction than infants labeled full-term. College students who later observed the videotapes made of the mother-infant interactions were able to accurately guess which label was assigned to the infants. The results of this study further support the existence of a prematurity stereotype and the impact of expectations on perceptions and behavior.  相似文献

Social Pragmatics: Preschoolers Rely on Commonsense Psychology to Resolve Referential Underspecification     

Julian Jara-Ettinger  Sammy Floyd  Holly Huey  Joshua B. Tenenbaum  Laura E. Schulz 《Child development》2020,91(4):1135-1149

Four experiments show that 4- and 5-year-olds (total N = 112) can identify the referent of underdetermined utterances through their Naïve Utility Calculus—an intuitive theory of people’s behavior structured around an assumption that agents maximize utilities. In Experiments 1–2, a puppet asked for help without specifying to whom she was talking (“Can you help me?”). In Experiments 3–4, a puppet asked the child to pass an object without specifying what she wanted (“Can you pass me that one?”). Children’s responses suggest that they considered cost trade-offs between the members in the interaction. These findings add to a body of work showing that reference resolution is informed by commonsense psychology from early in childhood.  相似文献   

Non-centralized control for flow-based distribution networks: A game-theoretical insight     

Julian Barreiro-Gomez  Carlos Ocampo-Martinez  Nicanor Quijano  José M. Maestre 《Journal of The Franklin Institute》2017,354(14):5771-5796

This paper solves a data-driven control problem for a flow-based distribution network with two objectives: a resource allocation and a fair distribution of costs. These objectives represent both cooperation and competition directions. It is proposed a solution that combines either a centralized or distributed cooperative game approach using the Shapley value to determine a proper partitioning of the system and a fair communication cost distribution. On the other hand, a decentralized non-cooperative game approach computing the Nash equilibrium is used to achieve the control objective of the resource allocation under a non-complete information topology. Furthermore, an invariant-set property is presented and the closed-loop system stability is analyzed for the non-cooperative game approach. Another contribution regarding the cooperative game approach is an alternative way to compute the Shapley value for the proposed specific characteristic function. Unlike the classical cooperative-games approach, which has a limited application due to the combinatorial explosion issues, the alternative method allows calculating the Shapley value in polynomial time and hence can be applied to large-scale problems.  相似文献   

Self-confidence and performance goal orientation interactively predict performance in a reasoning test with accuracy feedback     

Nadin Beckmann  Jens F. Beckmann  Julian G. Elliott 《Learning and individual differences》2009,19(2):277-282

This study takes an individual differences' perspective on performance feedback effects in psychometric testing. A total of 105 students in a mainstream secondary school in North East England undertook a cognitive ability test on two occasions. In one condition, students received item-specific accuracy feedback while in the other (standard condition) no feedback was provided. While accuracy feedback had, on average, no effect on test performance, differential effects were observed. Performance goal orientation and self-confidence moderated feedback effects on performance. The provision of accuracy feedback seemed to have performance optimising effects upon test takers with high performance goal orientation in combination with low self-confidence. The implications of these findings in relation to the validity of findings from psychological testing are discussed.  相似文献   

The uses of (digital) literacy     

Julian McDougall  Mark Readman  Philip Wilkinson 《Learning, Media and Technology》2018,43(3):263-279

This article shares research facilitated by a multinational technology provider, converging mobile networked technology (tablets) used across school and home, a technology enhanced community ‘third space’ providing workshops for students aged 6–9 with their parents/carers. The approach taken avoids the instrumental measurement of functional digital literacy competences, but instead seeks to negotiate a more nuanced and complex understanding of the ‘uses of literacy’ [from Hoggart, R. 1957. The Uses of Literacy. London: Pelican] in digital contexts and in a deeply situated, specific local setting. Working with our findings, we later put Amartya Sen’s concept of capability [Sen, A. K. 2005. “Human Rights and Capabilities.” Journal of Human Development 6 (2): 151–166; Sen, A. K. 2008. “Capability and Well-Being.” In The Philosophy of Economics, edited by D. M. Hausman, 3rd ed., 270–293. Cambridge: Cambridge University Press] to work on our data in order to provide a discussion on how the digital literacy community might distinguish digital competences as functionings from the ‘uses’ of such competences for a broader range of capabilities.  相似文献   

Community Level Factors and Child Maltreatment Rates   总被引：8，自引：1，他引：8  

Claudia J. Coulton  Jill E. Korbin  Marilyn Su  Julian Chow 《Child development》1995,66(5):1262-1276

Using census and administrative agency data for 177 urban census tracts, variation in rates of officially reported child maltreatment is found to be related to structural determinants of community social organization: economic and family resources, residential instability, household and age structure, and geographic proximity of neighborhoods to concentrated poverty. Furthermore, child maltreatment rates are found to be intercorrelated with other indicators of the breakdown of community social control and organization. These other indicators are similarly affected by the structural dimensions of neighborhood context. Children who live in neighborhoods that are characterized by poverty, excessive numbers of children per adult resident, population turnover, and the concentration of female-headed families are at highest risk of maltreatment. This analysis suggests that child maltreatment is but one manifestation of community social organization and that its occurrence is related to some of the same underlying macro-social conditions that foster other urban problems.  相似文献
