研究发现学习效能感会受到同伴支持的影响,同时它又是影响学生学业状况的重要前因变量。根据控制价值理论,本研究通过对3329名高一和高二学生的调查,考察在物理和化学学科中,学习效能感是否会在同伴学业支持和学业情绪中起到中介作用。发现：(1)同伴学业支持和学习效能感呈显著正相关;两者与高兴学业情绪显著正相关,与厌倦学业情绪显著负相关;(2)在控制了年龄、年级、性别和地域后,学习效能感在同伴学业支持和高兴学业情绪中起部分中介作用,在同伴学业支持和厌倦学业情绪中起完全中介作用;(3)在物理学科中,性别调节了学习效能感和学业情绪的关系。本研究验证并拓展了控制价值理论,对于如何提高中学生物理和化学学习的积极情绪有借鉴意义。     

Visual context processing and its development in gamers and non-gamers

Visual context processing was investigated in both action video game players and nonplayers using the Ebbinghaus illusion task (N = 312, 39.4% female) in a cross-sectional study design. When presented in context, players showed markedly poorer target size discrimination accuracy compared with nonplayers in the 6-, 7-, 8-, and 9-years old age groups, but this difference was reduced in 10-years old group and diminished in adults. When presented in isolation (no-context), the two groups displayed similar performance in all age groups. Furthermore, nonplayers (linear) and players (bell curve) showed profoundly different age-related differences in context processing. These findings provide evidence that players might have enhanced perceptual bias to process visual context in the transition from early childhood to early adolescence, and the differences between the two groups start at early ages and continue with distinct developmental profiles.     

Anticipation across modalities in children and adults: Relating anticipatory alpha rhythm lateralization,reaction time,and executive function

The development of the ability to anticipate—as manifested by preparatory actions and neural activation related to the expectation of an upcoming stimulus—may play a key role in the ontogeny of cognitive skills more broadly. This preregistered study examined anticipatory brain potentials and behavioral responses (reaction time; RT) to anticipated target stimuli in relation to individual differences in the ability to use goals to direct action (as indexed by measures of executive function; EF). A cross-sectional investigation was conducted in 40 adults (aged 18–25 years) and 40 children (aged 6–8 years) to examine the association of changes in the amplitude of modality-specific alpha-range rhythms in the electroencephalogram (EEG) during anticipation of lateralized visual, tactile, or auditory stimuli with inter- and intraindividual variation in RT and EF. Children and adults exhibited contralateral anticipatory reductions in the mu rhythm and the visual alpha rhythm for tactile and visual anticipation, respectively, indicating modality and spatially specific attention allocation. Variability in within-subject anticipatory alpha lateralization (the difference between contralateral and ipsilateral alpha power) was related to single-trial RT. This relation was more prominent in adults than in children, and was not apparent for auditory stimuli. Multilevel models indicated that interindividual differences in anticipatory mu rhythm lateralization contributed to the significant association with variability in EF, but this was not the case for visual or auditory alpha rhythms. Exploratory microstate analyses were undertaken to cluster global field power (GFP) into a distribution-free temporal analysis examining developmental differences across samples and in relation to RT and EF. Anticipation is suggested as a developmental bridge construct connecting neuroscience, behavior, and cognition, with anticipatory EEG oscillations being discussed as quantifiable and potentially malleable indicators of stimulus prediction.     

Brain bases of English morphological processing: A comparison between Chinese-English,Spanish-English bilingual,and English monolingual children

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.     

The role of effort type and intensity in children's decisions about effort-based outcomes

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.     

Childhood fantasy play relates to adult socio-emotional competence

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.     

亲子依恋与儿童抑郁症状的关系：儿童对环境的生物敏感性的作用及父母差异

不良的亲子依恋是导致儿童抑郁症状的风险因素,但其对儿童的影响会因儿童对环境的生物敏感性不同而存在差异。为探究家庭中母子、父子依恋对儿童抑郁症状的影响及儿童生物敏感性(本文中采用迷走神经抑制作为指标)在其中的作用,本研究结合行为任务、问卷报告、生理测量等多种研究手段,招募150名学龄儿童(平均年龄8.64岁,63名女孩)参与研究。结果表明：(1)学龄儿童的母子依恋水平高于父子依恋水平。(2)高水平的母子依恋与父子依恋会同等程度地降低儿童的抑郁症状。(3)儿童对环境的生物敏感性对母子依恋影响儿童抑郁症状路径的调节作用显著,生理上对环境更敏感(高迷走神经抑制)的儿童更易得益于高母子依恋,表现出较低的抑郁水平;但同时,这类儿童在母子依恋较低时也更易表现出较高的抑郁水平。(4)儿童的生物敏感性对父子依恋影响儿童抑郁症状路径的调节作用不显著,高父子依恋对生物敏感性水平不同的儿童均存在有利影响。(5)在不同情境中测量的迷走神经抑制对亲子依恋影响儿童抑郁症状的调节作用模式相似,表现出跨情境一致的特点。本研究率先揭示儿童迷走神经抑制与亲子依恋对儿童抑郁症状的联合作用机制及父母角色差异。     

Implementation and evaluation of a juvenile mental health training for law enforcement in a medium-sized jurisdiction

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.     

Family mental health during the COVID-19 pandemic: Changes in parent-adolescent internalizing symptoms in the United States

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.
