Simple discrimination training with differential responses to establish functional and equivalence classes with preschool children

The present study assessed whether simple discrimination training with differential responses would produce functional and equivalence classes with preschool children. In Experiment 1, we exposed 10 children to simple successive discrimination training in which they had to press different buttons (selection‐based responses). Response 1 (R1) was reinforced only in the presence of A1, B1, or C1, and Response 2 (R2) was reinforced only in the presence of A2, B2, or C2. We assessed the formation of functional classes by training new selection responses in the presence of one member of each class (A1‐R3, A2‐R4) and testing to see if these responses would occur in the presence of other members. Eight children responded consistently with functional class formation. Four of these eight children also responded consistently with the formation of equivalence classes. Experiment 2 investigated whether differential motor responses (i.e., gestures) would improve equivalence class yields. Three of six children showed both functional and equivalence class formation. In general, the results indicate that the simple discrimination procedure with differential responses yielded functional and equivalence class formation.     

Frequency and Intensity of Emotional Expressiveness and Preschool Children’s Peer Competence

Children’s emotional expressiveness with peers was examined as a predictor of social competence. Data were collected from 122 preschool children (57 boys, 65 girls; 86 European American, 9 African American, 17 Hispanic, and 10 other ethnicity) over a period of two?years. Observations of children’s peer interactions in Year 1 were coded for frequency and intensity of happiness, anger, sadness, and fear. Sociometric interviews and teacher ratings provided assessments of children’s peer competence in both Years 1 and 2. Frequent expression of happiness in Year 1 predicted higher social competence scores in Year 2, whereas frequent anger in Year 1 predicted lower peer competence Year 2. More intense anger and sadness in Year 1 predicted lower peer social competence scores in Year 2. Frequency and intensity of emotional expressiveness in Year 1 accounted for unique variance in peer competence in Year 2.     

Does Narrative Feedback Enhance Children's Motor Learning in a Virtual Environment?

Augmented feedback has motivational and informational functions in motor learning, and is a key feature of practice in a virtual environment (VE). This study evaluated the impact of narrative (story-based) feedback as compared to standard feedback during practice of a novel task in a VE on typically developing children's motor learning, motivation and engagement. Thirty-eight children practiced navigating through a virtual path, receiving narrative or non-narrative feedback following each trial. All participants improved their performance on retention but not transfer, with no significant differences between groups. Self-reported engagement was associated with acquisition, retention and transfer for both groups. A narrative approach to feedback delivery did not offer an additive benefit; additional affective advantages of augmented feedback for motor learning in VEs should be explored.     

An examination of the psychometric properties of scores on the Family Strain Index (FSI) in a general community sample

Given the potentially harmful effects of parenting stress on parents, children, and their relationship, it is critical to have a reliable and valid measure of parenting stress in clinical and community samples. The Family Strain Index (FSI) is a brief questionnaire designed to measure stress and demand on parents of children with ADHD. The present study is the first to evaluate the psychometric properties of scores on the FSI in a general community sample. Parents (89% mothers) of 550 preschool children (aged 2–5 years; 50% boys) sampled through 17 kindergartens located in Danish cities and villages completed the FSI, the ADHD Rating Scale (RS)‐IV Preschool Version, and a background questionnaire. FSI scores were characterized by restricted range and floor effects. The scale's construct validity was not supported and the measurement repeatability after 1 month was low. The scale did have convergent validity as levels of parenting stress were associated with perceived ADHD behavior in off‐spring, but overall, results did not encourage the use of the FSI as a measure of parenting stress in the general population. Measures that include more normative events may be more appropriate when attempting to capture parenting stress in general community samples.     

Sex differences in the development of physical aggression: An intergenerational perspective and implications for preventive interventions

This article reviews the state of knowledge on the development of chronic physical aggression (CPA), with the aim of identifying the most effective prevention strategies. We specifically focus on the early development of physical aggression, on sex differences in the use of physical aggression, and on the transmission of behavior problems from one generation to the other. The body of research on the development of CPA from the past three decades that we review shows increasing evidence that its prevention requires a long-term biopsychosocial developmental approach which also must include an intergenerational perspective. Recent genetic and epigenetic research has indicated that there are both important genetic and environmental effects on gene expression which start at conception. We conclude that one of the most effective strategies to break the intergenerational transmission of CPA involves giving long-term support to pregnant women with a history of behavior problems, their spouse, and their offspring.     

Reconceiving the field: Infant mental health,intersectionality, and reproductive justice

The field of infant mental health is conventionally comprised of professional discourses including developmental science, psychology, and psychiatry, among others, and involves spheres of practice as wide-ranging as pediatrics, maternal/child health, early intervention, early care and education, and child welfare. The World Association of Infant Mental Health [WAIMH] put out its position paper on the rights of infants in 2014 (amended in March 2016) in recognition of the human rights implications of professional understanding of infants’ unique, yet universal, developmental capacities and needs. This article links the policy issues outlined in the WAIMH position paper with critical issues in the field of reproductive justice, extending the reach of WAIMH's call to action on behalf of infants’ rights, and pointing the way toward potent alliances among interconnected movements. Connecting the dots among economic injustice, race-based health disparities, and gender inequities, the article demonstrates that it is not possible to safeguard infant mental health unless we make reproductive justice a reality.     

Brief report: Attentional Control Moderates the Relationship Between Attentional Bias and Anxiety in Children

This current study tested whether attentional control moderates the relationship between attentional bias to threat and anxiety in children. Children completed a self-report measure of attentional control and anxiety and an attentional bias task. Attentional control was examined as a moderator in the relationship between attentional bias and different dimensions of anxiety. The interaction between attentional control and attentional bias was significant for total and generalized anxiety. Although attentional control significantly moderated the relationship between attentional bias and anxiety, the direction of the interaction was not consistent with existing literature. Study implications and explanations for the study results are discussed.     

学龄前孤独谱系障碍儿童汉语核心语法的习得

学龄前孤独谱系障碍(Autism Spectrum Disorders; ASD)儿童对语言的习得程度是决定ASD儿童早期科学干预效果和最终预后水平的关键。以往ASD儿童语言研究多局限于英语ASD儿童, 较少有研究探讨不同语种ASD儿童语言习得的普遍机制。本研究拟结合汉语独特的语法属性, 通过多通道优先注视范式眼动实验考察2~5岁ASD儿童汉语核心语法的理解程度, 通过共同注意游戏评估ASD儿童的社会交流能力, 同时分析ASD儿童语言环境中相关语法结构的输入频率。研究旨在通过探讨学龄前ASD儿童的语法习得, 进一步探索人类语言习得的深层机制, 包括探索人类特有的语言机能对包括ASD儿童语言习得在内的人类语言习得的作用, 同时考察社会交流障碍与语言环境对人类语言习得过程的影响。     

自主阅读和伴读方式下3～4岁幼儿图画书阅读的眼动研究

研究以SMI眼动仪为工具考察了30名3～4岁幼儿在自主阅读和伴读方式下阅读图画书的特点。结果发现:(1)阅读方式对幼儿的眼动模式产生一定影响:伴读方式下儿童的平均注视时间更短,伴读方式有利于3～4岁幼儿对图画书的信息加工。(2)幼儿对图画书中关键信息的注视受到阅读方式的影响,表现为伴读方式下幼儿能更早注视关键信息。(3)幼儿在两种阅读方式下均表现为图画优先、人物主体优先和面部优先的特点而很少关注文字。     

联想学习与工作记忆在流体智力发展中的作用

以115名7、10、13岁儿童为研究对象,采用配对联想学习、倒序背数、字母-数字排序、图画概念和矩阵推理等测验,考察联想学习与工作记忆在流体智力发展中的作用。结果发现:联想学习与工作记忆在流体智力发展中均起着重要的作用,然而,在不同年龄上,两者对流体智力的作用并不相同。具体来说,在7岁时,联想学习对流体智力的作用显著,而工作记忆的作用不显著;到10岁和13岁时,工作记忆对流体智力的作用显著,而联想学习的作用不再显著。从效应量来看,随着年龄的增长,联想学习对流体智力的作用逐渐减小,而工作记忆的作用则逐渐增加。
