Speech directed towards young children ("motherese") is subject to consistent systematic modifications. Recent research suggests that gesture directed towards young children is similarly modified (gesturese). It has been suggested that gesturese supports speech, therefore scaffolding communicative development (the facilitative interactional theory). Alternatively, maternal gestural modification may be a consequence of the semantic simplicity of interaction with infants (the interactional artefact theory). The gesture patterns of 12 English mothers were observed with their 20-month-old infants while engaged in two tasks, free play and a counting task, designed to differentially tap into scaffolding. Gestures accounted for 29% of total maternal communicative behaviour. English mothers employed mainly concrete deictic gestures (e.g. pointing) that supported speech by disambiguating and emphasizing the verbal utterance. Maternal gesture rate and informational gesture-speech relationship were consistent across tasks, supporting the interactional artefact theory. This distinctive pattern of gesture use for the English mothers was similar to that reported for American and Italian mothers, providing support for universality. Child-directed gestures are not redundant in relation to child-directed speech but rather both are used by mothers to support their communicative acts with infants. 相似文献

The standard 2-4-6 task requires discovery of a single rule and produces success rates of about 20%, whereas the dual-goal (DG) version requests discovery of two complementary rules and elevates success to over 60%. The experiment examined two explanations of DG superiority: Evans' (1989) positivity-bias account, and Wharton, Cheng, and Wickens' (1993) goal-complementarity theory. Two DG conditions were employed that varied the linguistic labelling of rules (either positively labelled Dax vs. Med, or mixed-valence “fits” vs. “does not fit”). Solution-success results supported the goal-complementarity theory since facilitation arose in both DG conditions relative to single-goal tasks, irrespective of the linguistic labelling of hypotheses. DG instructions also altered quantitative and qualitative aspects of hypothesis-testing behaviour, and analyses revealed the novel result that the production of at least a single descending triple mediates between DG instructions and task success. We propose that the identification of an appropriate contrast class that delimits the scope of complementary rules may be facilitated through the generation of a descending instance. Overall, our findings can best be accommodated by Oaksford and Chater's (1994) iterative counterfactual model of hypotheses testing, which can readily subsume key elements of the goal-complementarity theory. 相似文献

Heuristic and analytic processing: age trends and associations with cognitive ability and cognitive styles 总被引:3,自引:0,他引:3
Kokis JV Macpherson R Toplak ME West RF Stanovich KE 《Journal of experimental child psychology》2002,83(1):26-52
Developmental and individual differences in the tendency to favor analytic responses over heuristic responses were examined in children of two different ages (10- and 11-year-olds versus 13-year-olds), and of widely varying cognitive ability. Three tasks were examined that all required analytic processing to override heuristic processing: inductive reasoning, deductive reasoning under conditions of belief bias, and probabilistic reasoning. Significant increases in analytic responding with development were observed on the first two tasks. Cognitive ability was associated with analytic responding on all three tasks. Cognitive style measures such as actively open-minded thinking and need for cognition explained variance in analytic responding on the tasks after variance shared with cognitive ability had been controlled. The implications for dual-process theories of cognition and cognitive development are discussed. 相似文献

In the U.S., modifications in family structure and in attitudes concerning marriage and family life have been numerous. Areas such as sexual behavior and alternative living arrangements have become highly varied and nontraditional compared to past generations. This study examined the attitudes of adolescents toward aspects of marriage and family life. The majority of adolescents expressed negative attitudes toward divorce and viewed marriage as a lifelong commitment. While only about a third of the adolescents expressed positive attitudes toward premarital sex, a majority indicated they would engage in sexual intercourse before marriage, or already have. Interestingly, about half of the adolescents held positive attitudes toward cohabitation. Lastly, the adolescents demonstrated a growing acceptance of premarital counseling and psychoeducational interventions regarding marriage and family life. 相似文献

Impact evaluation of the family expectations program and moderation by sociodemographic disadvantage
Lane L. Ritchie Scott M. Stanley Maggie O.T. Allen Galena K. Rhoades 《Family process》2023,62(1):201-215
The federal government, through the Administration for Children and Families (ACF), has funded community-based relationship education programs for couples, individuals, and families, with a strong focus on serving economically disadvantaged and racially diverse families. This study evaluated the impact of a 36-hour, workshop-based couple relationship education program that was funded by ACF using a randomized controlled trial (RCT) design and intent-to-treat (ITT) analyses. Participants were 1320 couples who were either expecting a baby or had a baby within the past 3 months, at the time of enrollment. Follow-up surveys were administered 12 months later. Analyses evaluated program impacts on relationship stability, constructive communication, and destructive conflict compared to a no-treatment control group. Analyses showed a statistically significant impact of the program on destructive conflict (d = 0.10) but not on constructive communication (d = 0.06) or stability (dCox = 0.10). Based on findings from previous evaluations, we also examined whether participants’ levels of sociodemographic disadvantage moderated these effects. There was significant moderation by sociodemographic disadvantage on constructive communication and destructive conflict, but not on stability. Effects were observed for those at higher levels of sociodemographic disadvantage. 相似文献

To understand the visual analysis of biological motion, subjects viewed dynamic, stick figure renditions of a walker, car, or scissors through apertures. As a result of the aperture problem, the motion of each visible edge was ambiguous. Subjects readily identified the human figure but were unable to identify the car or scissors through invisible apertures. Recognition was orientation specific and robust across a range of stimulus durations, and it benefited from limb orientation cues. The results support the theory that the visual system performs spatially global analyses to interpret biological motion displays. 相似文献

Neurofibromatosis type 1(NF1) is a complex and variable inherited disorder. The complexity and variability present particular difficulty for genetic counseling. Thirty-three people with NF1 of reproductive age were interviewed about their experience of genetic counseling, their past reproductive behavior and future intentions. One third reported having had no genetic counseling or not having it until after their first child. In part, this may be due to delay in diagnosis but also indicates poor access to genetic services. Only three people had ever been offered prenatal genetic testing and only one had accepted. Although testing is still technically difficult, the greatest deterrent to uptake of prenatal testing for NF1 is the variability of the disorder. However, six of the 17 people planning future pregnancies would want a test with a view to termination if necessary. Others would welcome testing in order to be prepared but not to terminate. We discuss some of the factors which influence reproductive decision making for people with NF1 and some of the difficulties in genetic counseling in such a variable and complex disorder. 相似文献

The UK government announced the establishment of an NHS National Genetics Education and Development Centre in its Genetics
White Paper. The Centre aims to lead and coordinate developments to enhance genetics literacy of health professionals. The
nursing program takes a strategic approach based on Ajzen’s Theory of Planned Behavior, using the UK nursing genetics competences
as the platform for development. The program team uses innovative approaches to raise awareness of the relevance of genetics,
working collaboratively with policy stakeholders, as key agents of change in promoting competence. Providing practical help
in preparing learning and teaching resources lends further encouragement. Evaluation of the program is dependent on gathering
baseline data, and the program has been informed by an education needs analysis. The challenges faced are substantial and
necessitate international collaboration where expertise and resources can be shared to produce a global system of influence
to facilitate the engagement of non-genetic nurses. 相似文献
