We examined the effects of three reinforcement histories on the persistence of task engagement by 2 fourth-grade students using a partially counterbalanced ABCDBCD design. In each condition, an experimenter made four student contacts during the first 2 min of each session (reinforcement baseline), followed by an 8-min extinction period. The reinforcement history that contained an instructional control component produced the greatest persistence in student engagement. The applied relevance of instructional control is discussed.  相似文献

Three groups of subjects were tested to investigate the effect of language on the relationship between recall span and articulation rate. Native English-speaking monolinguals and native Chinese-speaking monolinguals recalled only English or Chinese words, respectively. Chinese-English bilinguals recalled both English and Chinese words. Articulation rates for English and Chinese monolinguals and Chinese-English bilinguals in each language were also obtained. When recall span was regressed on articulation rate, the slopes for Chinese and English words were significantly different for the Chinese-English bilinguals. This difference was not due to language proficiency but to phonological differences between English and Chinese.  相似文献

There is growing evidence for the relationship between working memory and academic attainment. The aim of the current study was to investigate whether working memory is simply a proxy for IQ or whether there is a unique contribution to learning outcomes. The findings indicate that children’s working memory skills at 5 years of age were the best predictor of literacy and numeracy 6 years later. IQ, in contrast, accounted for a smaller portion of unique variance to these learning outcomes. The results demonstrate that working memory is not a proxy for IQ but rather represents a dissociable cognitive skill with unique links to academic attainment. Critically, we find that working memory at the start of formal education is a more powerful predictor of subsequent academic success than IQ. This result has important implications for education, particularly with respect to intervention.  相似文献

Multicultural psychology has 2 related but often disconnected streams, namely cross-cultural psychology and racial and ethnic minority psychology (Hall & Maramba, 2001). We propose that advances in both fields will be facilitated if there is greater cross-fertilization, especially in methodological approaches given that proponents in both fields are interested in studying and understanding the role and impact of culture on human behavior. To facilitate this cross-fertilization, we present 3 methodological approaches that would be of value in racial and ethnic minority psychology. First, we present an overview of the importance of and the approaches to evaluating and establishing measurement equivalence. Second, we discuss recent advances in the understanding of conceptual equivalence in light of indigenous approaches, cultural manipulation, and multilevel analysis. Third, we present a combined etic-emic approach to cross-cultural personality research as illustrated by the Cross-Cultural Personality Assessment Inventory developed by Fanny Cheung and her colleagues.  相似文献

This study integrated social comparison theory and self-esteem into the objectification theory framework to broaden our understanding of sexual objectification as it relates to body shame and disordered eating. Women (N?=?274) from a Midwestern U.S. college completed measures of sexual objectification via appearance feedback, body surveillance, body shame, body comparison, self-esteem, and disordered eating. Structural equation modeling indicated that this expanded model fit the data. Appearance feedback predicted body surveillance, body comparison, self-esteem and—unexpectedly—disordered eating. Body surveillance, body comparison, and self-esteem predicted body shame. Furthermore, hierarchical moderated regression revealed that body comparison moderated the body surveillance—disordered eating link; women who frequently monitored their body and compared it to others’ bodies reported the highest disordered eating.  相似文献

When Darwin's theory of natural selection threatened to put Paley's Designer out of a job, one response was to reemploy God as the author of the evolutionary process itself. This idea requires an account of how God might be understood to act in biological history. I approach this question in two stages: first, by considering God's action as creator of the world as a whole, and second, by exploring the idea of particular divine action in the course of evolution. As creator ex nihilo God acts directly in every event as its sustaining ground. Because God structures the world as a lawful order of natural causes, God also acts indirectly by means of creatures. More controversially, God might act directly within the world to affect the course of events; this action need not take the form of a miraculous intervention, if the natural order includes the right sort of indeterministic chance. In each of these ways God's purposes can shape evolutionary processes.  相似文献

Despite evidence for the importance of individual differences in expressive language during toddlerhood in predicting later literacy skills, few researchers have examined individual and contextual factors related to language abilities across the toddler years. Furthermore, a gap remains in the literature about the extent to which the relations of negative emotions and parenting to language skills may differ for girls and boys. The purpose of this longitudinal study was to investigate the associations among maternal sensitivity, children's observed anger reactivity, and expressive language when children were 18 (T1; n = 247) and 30 (T2; n = 216) months. At each age, mothers reported on their toddlers’ expressive language, and mothers’ sensitive parenting behavior was observed during an unstructured free-play task. Toddlers’ anger expressions were observed during an emotion-eliciting task. Using path modeling, results showed few relations at T1. At T2, maternal sensitivity was negatively related to anger, and in turn, anger was associated with lower language skills. However, moderation analyses showed that these findings were significant for boys but not for girls. In addition, T1 maternal sensitivity and anger positively predicted expressive language longitudinally for both sexes. Findings suggest that the relations between maternal sensitivity, anger reactivity and expressive language may vary depending on the child's developmental stage and sex.  相似文献

The purpose of this study was to investigate how brief experimental analyses (BEAs) could be used to identify effective interventions for Kindergartners (2 girls and 2 boys, 5 years and 7-10 months old) with low performance and/or growth slope in letter sound fluency (LSF). Interventions were tested within a multielement design with brief mini-reversals until an intervention yielding at least 20% improvement on a specific subskill measure or a curriculum-based measure of LSF was identified. BEA-identified interventions were implemented one-on-one for 5 to 9 weeks. A multiple-baseline design across participants showed large intervention effects (average adjusted d = 2.4) on general outcome measures, supporting treatment validity of BEAs. Findings extend the BEA literature to younger participants, early reading interventions, and early reading measures.  相似文献

Research on emotion processing in the visual modality suggests a processing advantage for emotionally salient stimuli, even at early sensory stages; however, results concerning the auditory correlates are inconsistent. We present two experiments that employed a gating paradigm to investigate emotional prosody. In Experiment 1, participants heard successively building segments of Jabberwocky "sentences" spoken with happy, angry, or neutral intonation. After each segment, participants indicated the emotion conveyed and rated their confidence in their decision. Participants in Experiment 2 also heard Jabberwocky "sentences" in successive increments, with half discriminating happy from neutral prosody, and half discriminating angry from neutral prosody. Participants in both experiments identified neutral prosody more rapidly and accurately than happy or angry prosody. Confidence ratings were greater for neutral sentences, and error patterns also indicated a bias for recognising neutral prosody. Taken together, results suggest that enhanced processing of emotional content may be constrained by stimulus modality.  相似文献

Background. Many countries rely on immigrants for population growth and to maintain a skilled workforce. However, many such immigrants face literacy‐related barriers to success in education and in the labour force. Aims. This meta‐analysis reviews experimental and quasi‐experimental studies to examine strategies for teaching English literacy to immigrant students. Method. Following an exhaustive and systematic search for studies meeting pre‐determined inclusion criteria, two researchers independently extracted data from 26 English as a Second Language (ESL) studies involving 3,150 participants. These participants consisted of ESL immigrant students in kindergarten through grade 6 who were exposed to English literacy instructional interventions. Measured outcomes were reading and writing. Results and Conclusions. Mean effect sizes vary from small to large, depending on instructional interventions and outcome constructs. Across several different grade levels, settings, and methodological features, pedagogical strategies used in teaching ESL to immigrant students are associated with increased competence in reading and writing. Collaborative reading interventions, in which peers engage in oral interaction and cooperatively negotiate meaning and a shared understanding of texts, produced larger effects than systematic phonics instruction and multimedia‐assisted reading interventions. The results show that the pedagogical strategies examined in this meta‐analysis produced statistically significant benefits for students in all grade levels. The findings also show that students from low socio‐economic status (SES) background benefit from ESL literacy interventions. However, significant heterogeneity was found in each subset. Educators and policy makers are encouraged to consider specific school contexts when making decisions about optimal pedagogical strategies. It is possible that contextual factors as well as ESL learner characteristics may influence the effectiveness of these strategies. To ensure literacy acquisition for immigrant students whose primary language is not English, it is important to continue to research successful literacy practices in ways that better inform educators and policy makers.  相似文献
