Infant bilingualism offers a unique opportunity to study the relative effects of language experience and maturation on brain development, with each child serving as his or her own control. Event-related potentials (ERPs) to words were examined in 19- to 22-month-old English-Spanish bilingual toddlers. The children's dominant vs. nondominant languages elicited different patterns of neural activity in the lateral asymmetry of an early positive component (P100), and the latencies and distributions of ERP differences to known vs. unknown words from 200-400 and 400-600 ms. ERP effects also differed for 'high' and 'low' vocabulary groups based on total conceptual vocabulary scores. The results indicate that the organization of language-relevant brain activity is linked to experience with language rather than brain maturation.  相似文献

We examined the longitudinal effects of situationally induced 2‐dimensional state goal orientations (i.e., achievement goals) on perceptions, performance, and satisfaction. Results (N = 268) indicated that high state learning cues led to higher perceived challenge and, for higher ability individuals, greater performance gains. Further, high state performance cues led to higher perceived effort. However, results revealed that state learning and performance effects were more complex than expected. State learning effects on challenge and state performance effects on effort were both stronger with other cues absent. Additionally, increasingly beneficial state learning cue effects were stronger for higher ability individuals. Thus, results provided support that state learning and performance goals are separate dimensions, and their interactive effects need further examination.  相似文献

In today's competitive workplace, individuals who are best prepared will have the greatest chance of obtaining and retaining jobs. Students can better prepare by developing the maximum possible knowledge and skills during their college educations. Research has shown that attitudes and perceptual variables have significant effects on development activity in organizations. We extend that research by using structural equations modeling to examine influences on attitudes toward one's college education. We posited that Big Five personality factors influence personal growth, readiness to change, and the perceived instrumentality of a university education and that these factors influence attitudes toward education. Results supported the posited model. A better understanding of antecedents of attitudes can enhance educational intervention effectiveness.  相似文献

Daily college drinking data often have highly skewed distributions with many zeroes and a rising and falling pattern of use across the week. Alcohol researchers have typically relied on statistical models with dummy variables for either the weekend or all days of the week to handle weekly patterns of use. However, weekend versus weekday categorizations may be too simplistic and saturated dummy variable models too unwieldy, particularly when covariates of weekly patterns are included. In the present study we evaluate the feasibility of cyclical (sine and cosine) covariates in a multilevel hurdle count model for evaluating daily college alcohol use data. Results showed that the cyclical parameterization provided a more parsimonious approach than multiple dummy variables. The number of drinks when drinking had a smoothly rising and falling pattern that was reasonably approximated by cyclical terms, but a saturated set of dummy variables was a better model for the probability of any drinking. Combining cyclical terms and multilevel hurdle models is a useful addition to the data analyst toolkit when modeling longitudinal drinking with high zero counts. However, drinking patterns were not perfectly sinusoidal in the current application, highlighting the need to consider multiple models and carefully evaluate model fit.  相似文献

Children with a history of child maltreatment often have limited social interactions with other children and adults. This study examined the effects of a Peer Engagement Program, consisting of peer mentoring and social skills training with positive reinforcement, in three children with low levels of oral and social interaction. A multiple baseline, single-subject research design was used to test whether introduction of the intervention was associated with increased, directly observed oral interaction and engagement in social activities with peers and adults. The Child Behavior Checklist (CBCL) and the Social Skills Rating Scale (SSRS) were administered before and after intervention. All children showed increased levels of oral and social interaction and improved scores on the SSRS and the CBCL.  相似文献

Younger and older African American and Caucasian American adults, who were matched by age (M age = 40.63 years), completed a survey on perceptions of aging and subjective age. The 2 groups did not differ in the age they considered someone to be old (M age = 74.5 years). However, when asked which age was the happiest age, African Americans chose a significantly younger age (M age = 18.26 years) than did Caucasian Americans (M age = 31.32 years), and this racial group difference interacted with age differences such that older Caucasian Americans named an older age than did younger Caucasian Americans. The authors found no such age difference for African Americans. When asked if old age was a happy time, 60% of Caucasian Americans answered yes, whereas only 2% of African Americans answered yes. These and other differences in images and concerns of old age and subjective age suggest a far more negative view of aging for African Americans and a need for changes in the provision of positive information about aging for this group.  相似文献

I argue that a metaphysical controversy, comparable with the ‘pantheism controversy’ of the late 18th century, is being played out today in the world-wide clash between religion and science, in which one side adheres to a strict materialism and the other admits phenomena of inspiritment as having a place in ontology. Just as the pantheism controversy was resolved, to some degree, via the concept of panentheism, so the solution to the contest between science and religion today might be pointing us in a panentheist direction. Taking into account (a) the empirical evidence of science, (b) the widespread evidence of spirit phenomena from different religions and spirit traditions, and (c) that the experience of spirit phenomena varies according to cultural frame of reference, I conclude that spirit phenomena must emanate from something that is common across cultures. The only thing that could be common across cultures is matter: it must be matter itself then that is imbued with spirit. While this position has affinities with panentheism, I argue that ‘panentheism’ is not in fact an appropriate name for it in the 21st century, as this name excludes the experience of many cultures for whom phenomena of inspiritment are not describable in any kind of theistic terms.  相似文献

The purpose of this article is threefold: (a) to describe the relevant ethical and legal issues associated with decisional capacity among minors and to discuss the importance of these concepts for children and adolescents living with HIV, (b) to provide a framework for assessing the decisional capacity of children and adolescents with HIV, and (c) to present a model for thinking about how to use this assessment data to guide action along the protection-autonomy continuum.  相似文献

We investigated whether a fearful expression enhances the effect of another's gaze in directing the attention of an observer. Participants viewed photographs of faces whose gaze was directed ahead, to the left or to the right. Target letters then appeared unpredictably to the left or right. As expected, targets in the location indicated by gaze were detected more rapidly. In nonanxious volunteers the effects of fearful gaze did not differ from neutral gaze, but fearful expression had a more powerful influence in a selected high anxious group. Attention is thus more likely to be guided by the direction of fearful than neutral gaze, but only in anxiety-prone individuals.  相似文献
