A review of efforts at social system change in 526 universal competence-promotion outcome studies indicated that 64% of the interventions attempted some type of microsystemic or mesosystemic change involving schools, families, or community-based organizations in an attempt to foster developmental competencies in children and adolescents. Only 24% of the reports provided quantitative data on the change that occurred in targeted systems. However, studies containing the necessary information produced several mean effect sizes that were statistically significant, and ranged from modest to large in magnitude. These data indicate that attempts to change social systems affecting children and adolescents can be successful. Future work should measure more thoroughly the extent to which the systemic changes that are targeted through intervention are achieved, and investigate how such changes contribute to the development and sustainability of the outcomes that might be demonstrated by participants of competence-promotion programs. The authors wish to thank David Wilson for supplying the macros used to calculate study level effect sizes and Mark Lipsey for supplying the SPSS macros used to weight effect sizes and calculate mean effects across studies. This study was supported in part by a grant from the William T. Grant Foundation (#2212) awarded to the first and last authors.  相似文献

Although recall hypermnesia (enhanced recall) over time with repeated testing has by now become an established empirical fact, its recognition counterpart, recognition hypermnesia, has defied clear-cut laboratory confirmation. In four studies, which relied on the retrieval component of recognition memory, it was shown that recognition memory, indexed by d′, reliably improved over three successive recognition tests. The stimuli consisted of 140 cartoons, each comprising a picture and a verbal caption. Recognition memory was tested on transforms or part-forms (parts) of the original stimulus material (pictures only, verbal paraphrases of the pictures, the latent content of the cartoons, or the combination of paraphrases and latent contents). The strongest effects were obtained when the originally presented cartoons were tested on their latent (deep semantic) contents. Recognition hypermnesia for part-forms or transforms of earlier presented stimuli has potentially wide-ranging implications since real-world recognition—of faces, texts, visual scenes—usually involves recognising stimuli that are variants, not exact copies, of the originally encountered materials.  相似文献

Previous research has suggested that the involuntary allocation of spatial attention to salient, irrelevant stimuli (i.e., attentional capture) is prevented when attention is in a focused state (e.g., Yantis & Jonides, 1990). Recent work has suggested that although focused attention may be necessary to prevent attentional capture by irrelevant stimuli, it is not sufficient (e.g., Folk, Leber, & Egeth, 2002). The present experiments provide evidence that attentional engagement, rather than attentional focusing, prevents capture. Observers performed a rapid serial visual presentation task in which they were asked to identify a target letter defined by color. Peripheral distractors that shared the color of the target produced evidence of attentional capture. This effect was completely eliminated, however, when the peripheral distractor was preceded by a central distractor designed to engage attention on the stream. It is concluded that attentional engagement serves to lock out capture by irrelevant, salient stimuli.  相似文献

Design research programs attempt to bring together the properties of available materials and the demands derived from intended applications. The logic of problem states and state transitions in such programs, including assessment criteria and heuristic principles, is described in settheoretic terms, starting with a naive model comprising an intended profile and the operational profile of a prototype. In a first concretization the useful distinction between structural and functional properties is built into the model. In two further concretizations the inclusion of potential applications is motivated and described for the case of drug research as well as the inclusion of potential realizations for the case of complex products. Next, another line of concretization of the naive model, the incorporation of potentially relevant properties, is sketched. Then the partial analogy between product- and truth-approximation is indicated. We conclude with some remarks about the usefulness of our models for products reaching the market in comparison to the the so-called social construction of technology approach.  相似文献

ObjectivesSocial goal orientations, which reflect ways of conceptualizing competence in terms of social relationships with others, have been researched minimally in the physical domain. While the relationship between task and ego orientations and motivational outcomes has been well-studied, the link of friendship, group acceptance, and coach praise orientations with enjoyment, perceived physical competence, and intrinsic motivation warrants further study.MethodMale and female middle-school students (N = 303) completed questionnaires assessing task, ego, coach praise, friendship, and group acceptance orientations; enjoyment; perceived physical competence; and motivation. Two approaches to data analysis (variable-centered, person-centered) examined whether social orientations were significantly related to motivational outcomes among adolescents.ResultsVariable-centered analysis (i.e., canonical correlation) showed that social orientations were related to enjoyment, perceived physical competence, and intrinsic motivation. Person-centered analyses (i.e., cluster analysis, MANOVA) classified participants with similar patterns of goal orientations and then compared the emergent groups on motivational outcomes. Participants who defined success using either higher task, ego, and social goal orientations or higher friendship and lower ego orientations reported the most adaptive responses (higher perceived competence, enjoyment, and intrinsic motivation).ConclusionsSocial orientations in sport are important to consider alongside task and ego orientations in research stemming from achievement goal theory. Defining success or competence in terms of social relationships can have positive motivational benefits in sport.  相似文献

We used meta-analysis to review 55 evaluations of the effects of mentoring programs on youth. Overall, findings provide evidence of only a modest or small benefit of program participation for the average youth. Program effects are enhanced significantly, however, when greater numbers of both theory-based and empirically based best practices are utilized and when strong relationships are formed between mentors and youth. Youth from backgrounds of environmental risk and disadvantage appear most likely to benefit from participation in mentoring programs. Outcomes for youth at-risk due to personal vulnerabilities have varied substantially in relation to program characteristics, with a noteworthy potential evident for poorly implemented programs to actually have an adverse effect on such youth. Recommendations include greater adherence to guidelines for the design and implementation of effective mentoring programs as well as more in-depth assessment of relationship and contextual factors in the evaluation of programs.  相似文献

This paper is concerned with vagueness in language, its relation to logico-philosophical questions on the one hand, and to so-called syncategorematic terms and their linguistic use on the other hand. It attempts to show that it is not language itself which is vague but rather the way we use it.  相似文献

In this article, we used results from two studies to show the need to go beyond linguistic equivalence to establish construct validity and measurement invariance in cross-cultural research. Study 1 examined Rosenberg Self-Esteem (RSE; 10 items) data from 156 Mainland Chinese youth (M = 13.8 years, SD = .53) and 213 Chinese-American youth (M = 13.6 years, SD = 2.1) from high socioeconomic status (SES) families. The Chinese translation of the RSE has been widely used. Study 2 included 1060 Mainland Chinese youth (M = 15.6 years, SD = 2.3) and 412 racially diverse American youth (M = 16.0, SD = 2.9) from all SES backgrounds. Data were collected with the third and newest edition of the Behavioural Assessment System for Children-Self Report of Personality (BASC-3-SRP; 189 items). We translated and back-translated the BASC-3-SRP between English and Chinese to establish linguistic equivalence. All participants were females. Study 1 showed that the RSE had acceptable internal consistency but lacked construct validity. Study 2 showed that the original and the translated BASC-3-SRP had good internal consistency and construct validity, but nine of its 16 subscales lacked measurement invariance. These results highlight measurement issues facing international and cross-cultural research.  相似文献

This study aimed to provide a quantitative synthesis of the effect of Self-determination theory (SDT) based instructional interventions on the motivational regulations of participants in organized physical activity. We conducted a systematic review and meta-analysis on experimental studies conducted before December 2021. The search using the online databases PsychINFO, PsychARTICLES, ERIC, SportDISCUS, and ProQuest Dissertations and Theses, and Google Scholar and other supplementary search strategies yielded 7774 articles, with 38 articles (142 effects and 12,457 participants) meeting the inclusion criteria. The articles were analyzed using a meta-analytic multivariate model. The study showed that SDT-based instruction had a positive heterogeneous small effect on intrinsic motivation (g = 0.29; CI 95% [0.17, 0.41]) and identified regulation (g = 0.23; CI 95% [0.10, 0.35]) and a negative heterogeneous, small effect on external regulation (g = −0.16; CI 95% [-0.31, −0.00]) and amotivation (g = −0.14; CI 95% [-0.28, −0.01]). SDT-based instruction did not have an effect on integrated regulation (g = 0.08; CI 95% [-0.11, 0.28]) nor introjected regulation (g = 0.03; CI 95% [-0.7, 0.13]). Univariate categorical moderator analyses highlighted multiple variables that impacted the size of the effects on the outcomes, including type of intervention and control group, length of study, age of participants, and study quality. Findings from the moderator analyses challenge the practical implications of SDT-based instructional interventions in improving motivation in organized physical activity. High-quality experimental trials using careful and precise conceptualizations of need-supportive behaviors and strategies would benefit the discipline.  相似文献

Two studies investigated adult age differences in the frequency and emotional consequences of motivational conflicts (i.e., feeling that one wants to or should do something else in a given situation). Study 1 compared younger and older adults. Study 2 included a more age-heterogeneous sample ranging from 20 to 70 years. Data were obtained using diary and experience-sampling methods. Multilevel regression showed that motivational conflict was associated with lower emotional well-being. With age, the frequency of motivational conflict decreased, while emotional well-being increased. Importantly, the age-related decrease in motivational conflicts partly accounted for the age-related increase in emotional well-being. Findings were consistent across studies and robust after the authors controlled for age differences in a number of control variables including time use. The authors conclude that an age-related decrease in motivational conflicts in daily life may be among the factors underlying the positive development of emotional well-being into older adulthood.  相似文献

A multilevel ecological analysis of issues that impact on children and families is advocated as the best theoretical framework for conceptualizing preventive interventions. Teen-age pregnancy and child sexual abuse are discussed as targets of preventive intervention: the former being an issue about which we have much information that has not been adequately used, whereas the latter is one about which we have too little information to be mounting the sweeping prevention programs that are rapidly coming into existence. Organized youth sports is then discussed as a neglected societal vehicle for prevention.  相似文献

A very low-cost, high-throughput laboratory data acquisition and experiment control system may be configured by using a star network architecture with a low-cost microcomputer as network controller and one or more microprocessor-based single-board controllers as satellites. A network of this type, using Apple II microcomputer ($1,500 with 48K RAM and one minidiskette drive) as main node and up to seven KIM-1 microcontrollers ($159 each) as satellites is described, and its development is discussed in detail.  相似文献

ObjectivesOur aim was to investigate the link between youth soccer players' perceptions of the coach-initiated motivational goal climate within their team and their perceptions of inclusion as a function of societal status. Societal status refers to one's national background which numerically forms the majority or a minority in a particular society.Design and methodsSurvey data was collected among 245 male youth soccer players (M = 12.9 years, SD = 1.60), who all played in culturally diverse teams in the Netherlands. The societal status of 94 players (38.4%) was majority, and 151 players (61.6%) were classified as minority. To test our main hypothesis, perceived inclusion as the dependent variable was hierarchically regressed on coach-initiated mastery goal climate perceptions, performance goal climate perceptions, societal status, and their interactions.ResultsOverall, mastery goal perceptions and performance goal perceptions of intra-team competition were positively and negatively related, respectively, to perceived team inclusion. As hypothesized, only among players with a societal minority status, perceptions of inclusion were higher when mastery goal climate perceptions were higher and performance goal climate perceptions were lower.Discussion and conclusionOur findings suggest that a coach-initiated mastery-oriented team climate may enhance an inclusive soccer environment in culturally and nationally diverse teams. For societal minority players, intra-team competition should be de-emphasized by the coach in order to strengthen the experience of inclusion.  相似文献

ObjectivesThis study examined youth ice hockey players' perceptions of individual feedback received from their coach, and the agreement and discrepancies between preferred and perceived coach feedback patterns, on athletes' perceptions of team motivational climate. The following research questions were answered: How does agreement in perceived and preferred coach feedback relate to task- and ego-involving motivational climate? How does the degree of discrepancy between perceived and preferred coach feedback relate to motivational climate? How does the direction of the discrepancy between perceived and preferred coach feedback relate to motivational climate?DesignThis study used non-probability based sampling within a cross-sectional (survey) design.MethodAthletes (n = 70) completed a self-report survey comprised of measures of coaching feedback and motivational climate. The data were examined using polynomial regression and response surface analysis.ResultsLinear associations were observed between coaching feedback and motivational climate, and unique associations between the perceived and preferred coach feedback discrepancies were distinctly related to increased perceptions of both task- and ego-involved motivational climates.ConclusionsThe type of feedback, purpose of the feedback, and agreement or discrepancy in perceptions and preferences for different feedback styles are important to understanding task- and ego-involved motivational climate in youth sport. Coaching programs should assist coaches in learning their athletes' preferences for positive and negative feedback in sport and matching these preferences with their individual feedback styles.  相似文献
