Background. Marsh's internal/external (I/E) frame of reference model depicts the relationship between achievement and self‐concept in specific academic domains. Few efforts have been made to examine concurrent relationships among cognitive ability, achievement, and academic self‐concept (ASC) within an I/E model framework. Aim. To simultaneously examine the influences of domain‐specific cognitive ability and grades on domain self‐concept in an extended I/E model, including the indirect effect of domain‐specific cognitive ability on domain self‐concept via grades. Sample. Tenth grade respondents (628 male, 452 female) to a national adolescent survey conducted in Taiwan. Method. Respondents completed surveys designed to measure maths and verbal aptitudes. Data on Maths and Chinese class grades and self‐concepts were also collected. Results. Statistically significant and positive path coefficients were found between cognitive ability and self‐concept in the same domain (direct effect) and between these two constructs via grades (indirect effect). The cross‐domain effects of either ability or grades on ASC were negatively significant. Conclusions. Taiwanese 10th graders tend to evaluate their ASCs based on a mix of ability and achievement, with achievement as a mediator exceeding ability as a predictor. In addition, the cross‐domain effects suggest that Taiwanese students are likely to view Maths and verbal abilities and achievements as distinctly different. 相似文献

The purposes of this study were to examine the effects of different distances and the inclusion and exclusion of acceleration and deceleration distances on the measurement of self-paced and fastest gait speeds in younger and older adults. The self-paced and fastest gait speeds of younger and older adults were measured over 4-m and 10-m walkways with the acceleration and deceleration distances included and excluded in the measuring distance. The results indicated gait speeds (both self-paced and fastest) measured over different distances were comparable only if a distance for acceleration and deceleration was excluded from the measuring distance to obtain stable and comparable gait speeds. Similar results were found for younger and older groups. 相似文献

The development of representations for taxonomic categories is influenced by many factors, such as age, life experiences, and education. It was hypothesized that Mosuos might be aware of taxonomic relations differently than Hans, as indicated by Sha (1996). Three experiments--word associations, lexicon decisions, and semantic categorizations--were conducted on young adults of Mosuos and Hans and consistent results were obtained: the Mosuos were found both similar to and different from the Hans in their experimental performance. They were apparently aware of taxonomic relations less than the Hans among categories of different levels and among categories of basic level, consistent with the conclusion that the uniqueness of a specific culture influences the people's representations for the hierarchically structured taxonomic categories (López, Atran, Coley, Medin & Smith, 1997). The present forms of education did not seem to be as effective as educators expected to help promote Mosuo children's development of knowledge of taxonomic categories. If school education would be available that is compatible with the cultural value of a relatively isolated, small population, such as Mosuos, and is of practical value for the young children to develop a better knowledge of the world, then a study would be of critical value into how educated individuals would be different from uneducated ones in their awareness of taxonomic relations. 相似文献

Future expectations have been important predictors of adolescent development and behavior. Its measurement, however, has largely focused on single dimensions and misses potentially important components. This analysis investigates whether an empirically-driven, multidimensional approach to conceptualizing future expectations can substantively contribute to our understanding of adolescent risk behavior. We use data from the National Longitudinal Survey of Youth 1997 to derive subpopulations of adolescents based on their future expectations with latent class analysis. Multinomial regression then determines which covariates from Bronfenbrenner's ecological systems theory are associated with class membership. After modeling these covariates, we examine whether future expectations is associated with delinquency, substance use, and sexual experience. Our analysis suggests the emergence of four distinct classes labeled the Student Expectations, Student/Drinking Expectations, Victim Expectations, and Drinking/Arrest Expectations classes according to their indicator profiles. These classes differ with respect to covariates associated with membership; furthermore, they are all statistically and differentially associated with at least one adolescent risk behavior. This analysis demonstrates the additional benefit derived from using this multidimensional approach for studying future expectations. Further research is needed to investigate its stability and role in predicting adolescent risk behavior over time. 相似文献

Over the prior decade, structural change efforts have become an important component of community-based HIV prevention initiatives. However, these efforts may not succeed when structural change initiatives encounter political resistance or invoke conflicting values, which may be likely when changes are intended to benefit a stigmatized population. The current study sought to examine the impact of target population stigma on the ability of 13 community coalitions to achieve structural change objectives. Results indicated that coalitions working on behalf of highly stigmatized populations had to abandon objectives more often than did coalitions working for less stigmatized populations because of external opposition to coalition objectives and resultant internal conflict over goals. Those coalitions that were most successful in meeting external challenges used opposition and conflict as transformative occasions by targeting conflicts directly and attempting to neutralize oppositional groups or turn them into strategic allies; less successful coalitions working on behalf of stigmatized groups struggled to determine an appropriate response to opposition. The role of conflict transformation as a success strategy for working on behalf of stigmatized groups is discussed. 相似文献

Concern for the impact of prenatal cocaine exposure (PCE) on human language development is based on observations of impaired performance on assessments of language skills in these children relative to non-exposed children. We investigated the effects of PCE on speech processing ability using event-related potentials (ERPs) among a sample of adolescents followed prospectively since birth. This study presents findings regarding cortical functioning in 107 prenatally cocaine-exposed (PCE) and 46 non-drug-exposed (NDE) 13-year-old adolescents.PCE and NDE groups differed in processing of auditorily presented non-words at very early sensory/phonemic processing components (N1/P2), in somewhat higher-level phonological processing components (N2), and in late high-level linguistic/memory components (P600).These findings suggest that children with PCE have atypical neural responses to spoken language stimuli during low-level phonological processing and at a later stage of processing of spoken stimuli. 相似文献
