This study examined early pragmatic skill development in a group of 38 children with severe or profound hearing loss between 1 and 4 years of age who were enrolled in a simultaneous communication (SC) approach to language learning. Both their use of intentionally communicative acts and their use of language were studied in an analysis of 30-min play sessions between a child and the primary caregiver. Results were compared with previously published data from two age-matched groups: 38 deaf children who were enrolled in oral communication (OC) programs and 84 normally hearing (NH) children. All groups showed a significant improvement with age in the communicative behaviors measured; therefore, the overall trend was toward growth-in all age groups-even when the rates of growth differed. By age 3 years, a pattern of communicative function use had emerged in all three groups. Patterns exhibited by deaf children in the SC and OC groups were similar to each other and to younger NH children but dissimilar to NH age mates. Although the use of signed input by normally hearing parents and teachers did not serve to ameliorate the profound effects of hearing loss on communication development in SC children, it did provide some early advantages. The children in SC groups did not exhibit an advantage over children in OC groups in their overall frequency of communication or the breadth of their vocabulary but they began using words earlier and used mature communicative functions significantly more often. Although children in the OC groups did not exhibit a significant advantage in the overall amount of speech used, they showed an advantage in the breadth of their spoken vocabulary in a conversational setting. Implications for early intervention programming are discussed.  相似文献

The present study investigated outreach activities, developed by STEM-based companies or universities in co-creation with secondary education with the aim to inform students about and motivate them for a career in STEM by connecting the work-context with school-science. Although many of such activities are being offered, little is known about their effects. We investigated students’ perceptions with the outreach learning environment, perceived need-fulfilment, self-reported motivation and attitudes towards STEM. Data were gathered from 729 high-school students engaged in 12 activities in the USA and the Netherlands. The students completed a questionnaire, which contained questions about four elements of our theoretical frame based on the Self-Determination-Theory (SDT). Perceived needs-fulfilment and motivation were measured using the basic-psychological-needs-scale and the self-regulation-questionnaire. Attitudes were measured using the test-of-science-related-attitudes. Learning environment perceptions were measured in a previous study using subscales of what-is-happing-in-this-classroom (WIHIC), constructivist-learning-environments-scale (CLES) and classroom-environment-scale (CES) and typified by activity characteristics. Multilevel analyses of variance were conducted for the two motivation scales (controlled and autonomous-motivation) and the two attitude scales (social-implication and career-interest). Activity characteristics explained almost all variance in these variables between activities. Specific characteristics of outreach activities that statistically significantly related to autonomous motivation and positive general attitudes towards STEM were: workshop-format, understanding science, an out-of-school component. The attitude towards a possible STEM-career was positively associated with autonomous-motivation and negatively associated with controlled-motivation. Thus, outreach learning environments indeed created opportunities to increase students’ motivation in STEM and attitude towards STEM, but the impact varied according to particular characteristics of the activities.  相似文献

The development of self‐regulation has been studied primarily in Western middle‐class contexts and has, therefore, neglected what is known about culturally varying self‐concepts and socialization strategies. The research reported here compared the self‐regulatory competencies of German middle‐class (= 125) and rural Cameroonian Nso preschoolers (= 76) using the Marshmallow test (Mischel, 2014). Study 1 revealed that 4‐year‐old Nso children showed better delay‐of‐gratification performance than their German peers. Study 2 revealed that culture‐specific maternal socialization goals and interaction behaviors were related to delay‐of‐gratification performance. Nso mothers’ focus on hierarchical relational socialization goals and responsive control seems to support children's delay‐of‐gratification performance more than German middle‐class mothers’ emphasis on psychological autonomous socialization goals and sensitive, child‐centered parenting.  相似文献

Although epidemiological data provide evidence that early life experience plays a critical role in human development, the mechanism of how this works remains in question. Recent data from human and animal literature suggest that epigenetic changes, such as DNA methylation, are involved not only in cellular differentiation but also in the modulation of genome function in response to early life experience affecting gene function and the phenotype. Such modulations may serve as a mechanism for life‐long genome adaptation. These changes seem to be widely distributed across the genome and to involve central and peripheral systems. Examining the environmental circumstances associated with the onset and reversal of DNA methylation will be critical for understanding risk and resiliency.  相似文献

Practices regarding the reporting of reliability coefficients in 3 journals from 1990 to 1997 were examined. Given that scores, not tests, are reliable or unreliable, particular attention was paid to the provision of reliability coefficients computed for the data actually being analyzed in substantive studies. One third of the articles reviewed made no mention of reliability. Almost 36% of the articles provided reliability coefficients for the data being analyzed. Examples of good reporting practices are provided. In 2 of the 3 journals reviewed, there was little change in the frequency and style of reliability reporting in the period covered. The authors suggest a modification in editorial journal policies to bring about a change in reliability-coefficient reporting practices.  相似文献

The study aimed to investigate the pedagogy and beliefs of Icelandic pre‐school and first‐grade teachers during times of immense changes in the policy and trends of early childhood education. The practices of 2 pre‐school teachers working with the oldest pre‐school children and 2 primary school teachers working with the youngest primary school children were examined. Qualitative methods were used, including participant observations, interviews, and document collection. The results of the study show differences in the practices of the two pairs of teachers and the social contexts that influenced the teachers' practices. The degree of control the teachers had over their work varied between school levels and the degree of control the children had over their learning also varied between school levels. The results indicate that the downward pressure of academic subjects is becoming evident.  相似文献

Research on Asian Americans and their psychological adjustment is limited. Consisting of two cross-sectional studies, the present investigation examined the relationships among self-concealment, mindfulness, emotional distress in stressful interpersonal situations, and general psychological ill-health in Asian American college students, and in comparison with European American counterparts. In the Asian Americans, self-concealment was found to be positively related to general psychological ill-health and negatively related to mindfulness. In both ethnic groups, mindfulness was found to be negatively related to general psychological ill-health. Findings suggest that, as seen with European American counterparts, both self-concealment and mindfulness may be important concepts in understanding the psychological adjustments of Asian American college students.  相似文献

To date, scholarship on international students has generally focused on flows from non‐western economies to the main English‐speaking destination countries (such as the United States, the United Kingdom and Australia). In contrast, we draw on a qualitative study of 85 UK students who have either completed or are considering undertaking a degree programme overseas. We found that, in opposition to a common image of ‘international students’, UK students are not overtly motivated by ‘strategic’ concerns. Instead, they are seeking ‘excitement’ and ‘adventure’ from overseas study and often use the opportunity to delay the onset of a career and prolong a relatively carefree student lifestyle. Despite these ostensibly ‘disinterested’ objectives, however, UK students remain a highly privileged group and their experiences serve only to facilitate the reproduction of their privilege. The paper calls for a more critical analysis of the spatially uneven and socially exclusive nature of international higher education.  相似文献
