There are reasons to believe that infant‐directed (ID) speech may make language acquisition easier for infants. However, the effects of ID speech on infants' learning remain poorly understood. The experiments reported here assess whether ID speech facilitates word segmentation from fluent speech. One group of infants heard a set of nonsense sentences spoken with intonation contours characteristic of adult‐directed (AD) speech, and the other group heard the same sentences spoken with intonation contours characteristic of ID speech. In both cases, the only cue to word boundaries was the statistical structure of the speech. Infants were able to distinguish words from syllable sequences spanning word boundaries after exposure to ID speech but not after hearing AD speech. These results suggest that ID speech facilitates word segmentation and may be useful for other aspects of language acquisition as well. Issues of direction of preference in preferential listening paradigms are also considered.  相似文献

Organisations providing human services are under increasing pressure to demonstrate quality from a range of sources such as new legislation and new requirements for government funding. Four dimensions for examining quality, derived from program evaluation theory, illustrated some of the contradictions surrounding these expectations. The research used a qualitative and grounded approach to exploring clients', volunteers' and coordinators' notions of quality service. The clients' and volunteers' perceptions of quality were highly experiential, related to the specific context and focussed on strong trusting personal relationships. Clients were also very conscious of their lack of power. Coordinators used a combination of approaches to try to satisfy the demands of clients, volunteers and bureaucracy.  相似文献

Family therapy doctoral students from American Association for Marriage and Family Therapy-accredited programs are required to complete a full-time clinical internship. The literature provides little information about these internship experiences. Two doctoral-level marriage and family therapists summarize their professional and personal experiences in their internships located within a multidisciplinary healthcare setting. In addition, their supervisor reports on her experiences working with marriage and family therapy doctoral interns. We hope that this case report will stimulate all interns and their supervisors to provide feedback to their internship sites and graduate programs about their clinical training and the extent to which the programs prepared them for their marriage and family therapy careers in the larger health and mental health community.  相似文献

Parenting stress has a range of effects on parents and their children. Despite existing evidence on the effectiveness of family-based interventions on reducing parenting stress, little is known about the mechanism of change that contributes to its reduction. This study investigates the mechanism of change in a parenting programme (Parenting for Lifelong Health [PLH]) on reducing parenting stress among parents of adolescents in South Africa. A pragmatic cluster randomized controlled trial was conducted among a total sample of 552 parents and primary caregivers (aged, M = 49.37; SD = 14.69) who were recruited from 40 communities in South Africa's Eastern Cape Province. A mediation analysis was performed to investigate direct and indirect effects using PROCESS macrostatistical software. The findings of the study indicate that parenting stress reduction operates via three significant mediators: improved parent–child relationship (β = 0.058, P < 0.000), reduced parental depression (β = −0.103, P < 0.000) and reduced family financial strain (β = −0.049, P < 0.000). The findings of the study highlight the importance of considering child, parental and contextual factors in the design and development of interventions aimed at reducing parenting stress in families in low- and middle-income settings.  相似文献

Many contemporary support services for children and young people (CYP) in out-of-home-care have adopted a collaborative approach to service provision in order to best meet the complex needs of clients. The purpose of this study was to gain a better understanding of the perceptions of Evolve Behaviour Support Services (EBSS) frontline and managerial staff delivering services to CYP in out-of-home-care with disability and complex behaviours regarding interagency/stakeholder collaboration. Views about the number and nature of collaborative partnerships, factors which facilitate or hinder effective relationships and advantages (including unintended benefits) of collaboration were sought. Qualitative interviews with 21 participants highlighted issues around: (1) general and agency/stakeholder specific issues and barriers, and (2) benefits of collaboration. The collaborative approach to service provision was seen as greatly enhancing the effectiveness of EBSS' response and ability to meet the range of CYP's complex needs, as well as having benefits for carers and service providers. Nevertheless, difficulties with collaboration were also encountered. Frequently identified challenges included reduced stakeholder engagement, differences in professional backgrounds and practice frameworks, unequal initiation of contact and follow-up, organisational disparities, communication and information sharing problems, frequent stakeholder turnover and geographical barriers in rural/remote areas.  相似文献

In migration research there has not been much work on temporal dimensions of migration experiences (with the exception of Griffiths in this journal). This article investigates migrant students’ temporal framings of their lived versus imagined school careers, drawing on participant observation and interviews with students in language introduction classes in upper secondary school in Sweden. The findings document student experiences of temporal desynchronies: as seen in reports of slow time and repetition, suspended time, temporal uncertainty and blockage. The analyses highlight the students’ experiences of being temporally out of line (in Ahmed’s words). The narratives of their past and future school lives reveal a discontinuity between the students’ lived school experiences, on the one hand, and imagined school careers on the other, contrasting life as lived with both their own hope and plans and with the school careers of other students. The analyses highlight the importance of including temporal dimensions in the analyses of post-migration school landscapes.  相似文献
