The present study explores relations between young children's understanding of mind and parental emotional expression and disciplinary style, along with gender differences in these relations. Participants were recruited from a study of 125 same-sex twin-pairs (58% female; group mean age 5 43 months, SD 5 1 month). Each child received a comprehensive set of theory-of-mind tasks, and was filmed at home for 20 minutes in dyadic interactions with the primary caregiver, who was also interviewed about disciplinary strategies. Ratings of discipline and positive and negative parental affect and control were made from direct observation, from the interview, and from the videoed interactions. Strong correlations were found between family SES, parenting measures, and child verbal IQ and theory-of-mind score. However, regression analyses showed that parental behaviours were significant predictors of children's theory-of-mind performance, even when sex, verbal IQ and family SES were taken into account. Sex differences in these relations were also identified; parental affect was especially salient for understanding of mind in girls, while discipline was more salient for boys. Taken together, these findings highlight the importance of individual differences in the proximal processes associated with early understanding of mind, and suggest that development in mental-state awareness is associated with distinct aspects of parenting for girls and boys.  相似文献

This article explores whether it is possible to understand the perspectives of people with whom we find it difficult or impossible to empathise, because their moral and political views are very different to our own. Focusing on our dilemmas in carrying out qualitative research with conservative evangelicals and anti‐abortion activists, we take issue with the assumption that understanding is connected with the presence of rapport and empathy in research interviews. This article argues instead that a reflexive approach, which considers researchers’ orientations towards their subject and their respondents and their emotional journeys through the research process, will enable more comprehensive interpretation of our research material.  相似文献

This paper is based on findings of a Welsh Assembly Governmentfunded review of children’s independent advocacy servicesin Wales with reference to their involvement in complaints madeby children, or by their parents or carers on their behalf,about local authority social services. It draws, primarily,upon qualitative interviews with local authority children’scomplaints officers, whose task is to receive complaints orconcerns, field these to appropriate social services staff,maintain oversight of their progression and keep complainantsinformed of developments. The paper describes the challengesthat complaints officers perceive children encounter in movingcomplaints forward, especially in a context where independentadvocacy services are involved and where these services areviewed with some suspicion by social services staff. It suggeststhat complaints officers play a pivotal part in managing thesometimes contested and complex interface between service providerand child and may do so from a position of limited authorityand influence. The role of complaints officers in engaging withcomplainants and their advocates, and with those colleaguesimplicated in complaints, has rarely been the topic of research.This paper provides accounts from these key staff that helpilluminate the tensions and difficulties that can enter thechildren’s complaints process.  相似文献

We report quantitative results from a large online survey of 5010 U.K. informants' reactions to 34 different accents of English, based on simple accent labels. Patterns of accent evaluation, in terms of adjudged levels of prestige, social attractiveness and some other variables, in many regards confirm broad findings from earlier research. Accent‐types associated with ‘standard’ speech are, for example, strongly favoured in the prestige and attractiveness dimensions. Several urban U.K. vernaculars, but not all, are systematically downgraded. On the other hand, robust differences emerge which have not been strongly evidenced previously – particularly differences according to informant gender (with females regularly producing more favourable evaluations) and region (with informants often favouring their own and linked varieties). There are also some important effects by informant age, for example with younger informants attributing less prestige to ‘standard’ accents. We interpret the findings as indicating rather persistent U.K. language‐ideologies around accent difference that are being reconstituted only gradually and in specific regards.  相似文献

Multistage models have become the basic paradigm for modeling carcinogenesis. One model, the two-stage model of carcinogenesis, is now routinely used in the analysis of cancer risks from exposure to environmental chemicals. In its most general form, this model has two states, an initiated state and a neoplastic state, which allow for growth of cells via a simple linear birth-death process. In all analyses done with this model, researchers have assumed that tumor incidence is equivalent to the formation of a single neoplastic cell and the growth kinetics in the neoplastic state have been ignored. Some researchers have discussed the impact of this assumption on their analyses, but no formal methods were available for a more rigorous application of the birth-death process. In this paper, an approximation is introduced which allows for the application of growth kinetics in the neoplastic state. The adequacy of the approximation against simulated data is evaluated and methods are developed for implementing the approximation using data on the number and size of neoplastic clones.  相似文献
