How do early bilingual experiences influence children's neural architecture for word processing? Dual language acquisition can yield common influences that may be shared across different bilingual groups, as well as language-specific influences stemming from a given language pairing. To investigate these effects, we examined bilingual English speakers of Chinese or Spanish, and English monolinguals, all raised in the US (N = 152, ages 5–10). Children completed an English morphological word processing task during fNIRS neuroimaging. The findings revealed both language-specific and shared bilingual effects. The language-specific effects were that Chinese and Spanish bilinguals showed principled differences in their neural organization for English lexical morphology. The common bilingual effects shared by the two groups were that in both bilingual groups, increased home language proficiency was associated with stronger left superior temporal gyrus (STG) activation when processing the English word structures that are most dissimilar from the home language. The findings inform theories of language and brain development during the key periods of neural reorganization for learning to read by illuminating experience-based plasticity in linguistically diverse learners. 相似文献

Despite the importance of persistence in early learning, we know little about how children reason about outcomes that result from their efforts. Here we examined the role of effort type (i.e., physical vs. cognitive) and intensity (i.e., high vs. low effort) in shaping children's decision making about effort-based rewards. Five- to 7-year-olds (N = 133) were assigned to one of four conditions (High Physical Effort, Low Physical Effort, High Cognitive Effort, Low Cognitive Effort) and completed a series of tasks to construct a toy. Tasks varied in the type (physical/cognitive) and intensity (high/low) of effort required to complete them. After constructing their toy, children completed a series of tasks to probe how much they valued that toy. Across conditions, children preferred their toy and gave it a higher monetary value, relative to a stranger's. However, when choosing their toy came at a cost, children no longer preferred it. Only children who built their toy through either cognitive or low effort were willing to incur a cost for their toy. Older children, across conditions, were also more likely to incur a cost for their toy. These findings demonstrate that by age five, children are sensitive to variations in effort type and intensity, and these factors shape how they evaluate effort-based rewards. 相似文献

Childhood fantasy play and creation of imaginary companions are thought to confer socio-emotional benefits in children, but little is known about how they relate to socio-emotional competence in adulthood. A total of 341 adults (81 males) aged 18 and above (M = 31.47, SD = 12.62) completed an online survey examining their fantasy play as a child, their childhood imaginary companion status, and their adult socio-emotional competence. Adults who reported higher levels of childhood fantasy play were found to be significantly more prosocial, empathetic, and emotionally intelligent than their counterparts after controlling for demographic factors. Recall of a childhood imaginary companion, however, was significantly related only to higher scores for perspective-taking and did not explain unique variance in any adult competence measure. Findings suggest that engagement in fantasy play during childhood may be a precursor to later socio-emotional competence, while benefits previously associated with imaginary companions specifically may not extend into adulthood. 相似文献

This article contains the principal ideas that I presented in four different sessions at the IRAS 2022 conference, on the theme “‘We' and ‘They’: Cross-Cultural Conversation on Identity.” Focusing on the central topic, the article begins with (i) the contents of my opening lecture; followed by (ii) a broad outline of the concerns discussed in my book, Cross-Cultural Conversation: A New Way of Learning, intertwined with glimpses of the intellectual journey that led me to CCC, delivered in the Book-discussion session; (iii) a summary of the main ideas about the importance of meeting of religions today, which formed the background for the CCC Panel discussion on religion, where I was in conversation with spokespersons of five world religions; and (iv) my comments on how science–religion dialogue can help promote a sense for human solidarity by combining knowledge with wisdom, in the concluding session. 相似文献

The need for specialized training programs that are focused on youth mental health needs, awareness of community-based services, and de-escalation skills is growing across law enforcement agencies due to calls for service that involve youth in mental health crisis. The current study evaluates a juvenile mental health training for law enforcement that was developed based on agency needs. The training was completed by 159 officers and a pre-/post-test design was used. Findings suggest that officers were satisfied with the training and improvements were seen across several training constructs (confidence, preparedness, stigma, resource awareness, and de-escalation skills). Satisfaction with the training predicted change in confidence and preparedness. Recommendations for future research and the implementation of juvenile mental health trainings are discussed. 相似文献

The current paper examined the temporal linkage of internalizing symptoms among parent-adolescent dyads during the beginning of the COVID-19 pandemic, and whether COVID-19-related concerns were associated with parent-adolescent linkage of symptoms. Using a 5-week survey-based study, parent-adolescent dyads filled out weekly surveys measuring COVID-19 concerns and internalizing symptoms. Parent and adolescent depressive symptoms did not change over time; however, adolescents experienced decreases in anxiety. Parent-adolescent dyads exhibited linkage in depressive symptoms but not anxiety symptoms. However, linkage in anxiety symptoms varied by parent's COVID-related stress. Study findings provide insight into how COVID-19 disruptions impacted family well-being during adolescence. 相似文献

This paper examines the ethical issues of conflict of interest raised by the burgeoning development of physician involvement in for-profit entrepreneurial activities outside their practice. After documenting the nature and extent of these activities, and their potential for conflicts of interest, the paper assesses the major arguments for and against physicians' referral of patients to facilities they own or in which they invest. The paper concludes that an outright ban on such activity seems ethically warranted. 相似文献

从情绪描述看青少年期到成人期认知结构的发展 总被引:1,自引:0,他引:1
该研究依据研究者制定的认知发展水平评价系统,对年龄范围在13—55岁之间的90名被试关于生气、害怕、伤心、高兴四种情绪的自我描述进行了评价分析。结果表明,青少年期的思维具有形式化、外在、抽象等特点,成人期的思维具有内在、具体、形象等特点,前者具有刻板性、封闭性,后者具有灵活性、开放性。 相似文献
