孤独症谱系障碍(Autism Spectrum Disorder, ASD)早期识别有助于早期诊断和早期干预的实施, 对于改善ASD儿童发育结果至关重要。高风险前瞻性纵向研究以高风险婴儿(ASD儿童的年幼同胞, 入组年龄小于12个月)作为主要研究对象, 通过对ASD高风险婴儿(24至36个月之间诊断为ASD的高风险婴儿)的早期发育轨迹的描绘和核心症状早期表现的识别, 为ASD早期识别提供了重要依据。未来可以增加被试数量、延长观察时间并密集观察时间点、关注伴发障碍、综合考虑遗传、环境和文化因素影响, 并结合早期干预研究进行深入探索。未来在中国开展相关研究具有重要的科学价值和临床意义。  相似文献

以汉语把字句和被字句为材料,采用学习-再认方式,考察基于同义关联的句子错误记忆及其发展性逆转现象和句式效应。实验1结果发现高二和初二校正后的关键诱饵句错误再认率显著高于小学五年级,把字关键诱饵句校正后的错误再认率显著高于被字句,表明基于同义关联的句子错误记忆存在发展性逆转现象和句式效应。实验2结果发现三个年级关键诱饵句与无关句的错误再认率差异均不显著,表明去除同义关联后,句子错误记忆现象被抑制。结果表明,同义关联能诱发句子错误记忆,且句子错误记忆存在发展性逆转现象和句式效应。  相似文献

The generality and long-term maintenance of a pairing procedure designed to improve the efficacy of less intrusive procedures were evaluated for the treatment of problem behavior maintained by automatic reinforcement exhibited by 2 individuals with developmental disabilities. Results suggested that a less intrusive procedure could be established as a conditioned punisher by pairing it with an effective punisher contingent on problem behavior. Generalization across multiple therapists was demonstrated for both participants. However, generalization to another setting was not achieved for 1 participant until pairing was conducted in the second setting. Long-term maintenance was observed with 1 participant in the absence of further pairing trials. Maintenance via intermittent pairing trials was successful for the other participant.  相似文献

The objectives of the study were to model the developmental trajectories of physical aggression (PA) from toddlerhood to pre-adolescence and to identify risk factors that distinguish typical (normative) from atypical developmental patterns. Ten cohorts of approximately 1,000 children (n = 10,658) drawn form a nationally representative (Canadian) sample were followed over 6 years. Using a group based trajectory approach, we identified three groups of children with distinct developmental trajectories between 2 and 11 years of age. One third of the children (31.1%) followed a low desisting trajectory, reflected in infrequent use of PA in toddlerhood and virtually no PA by pre-adolescence. The majority of children (52.2%) followed a moderate desisting trajectory, reflected in occasional use of PA in toddlerhood and infrequent use by pre-adolescence. One sixth of the children (16.6%) followed a high stable trajectory of PA. Multivariate logistic regression indicated that children in the high PA trajectory group were more likely to be boys (OR: 1.67; CI: 1.5–1.87), from low income families (OR: 1.4; CI; 1.27–1.67), from families where the mother had not completed high school (OR: 1.20; CI: 1.05–1.38) and who reported using hostile/ineffective parenting strategies (OR: 1.16; CI: 1.14–1.18). In sum, the results indicate that the typical developmental pattern of PA was one of occasional and declining use over time. However, about one sixth of children, mostly boys from disadvantaged families, exhibited an atypical developmental pattern reflected in more frequent and stable use of PA. The results suggest that most children learned relatively well to inhibit PA by the end of childhood and that a minority failed to do so. Family risks traditionally found to be associated with antisocial behaviors during adolescence appear to interfere with the socialization of PA during early and middle childhood.  相似文献

Violence prevention programs with varying degrees of scientific support have proliferated in the United States and elsewhere. This paper previewed a broad range of programs involving youth, families, or systems that aimed to prevent or reduce violence-related behavior. The purpose of the review was to address critical issues concerning (1) target level of programming, (2) theory-driven versus problem-driven conceptualization, (3) cultural considerations, (4) developmental considerations, (5) intervention fidelity, and (6) outcome and impact assessment. Conclusions about these issues address tendencies and trends across programs.  相似文献

综合运用课堂观察、访谈和问卷调查法,本研究以263名小学1~6年级学生为被试,考察了小学生课堂参与的类型及其发展特点。结果表明:1)根据学生课堂参与的性质、参与的程度可以将小学生划分为三类,即消极参与型、主动参与型和被动参与型;2)从总体分布上看,小学生课堂参与的类型是比较多样化的,相比较而言,被动参与型的人数最多,主动参与型次之,消极参与型最少;3)在学习成绩和自我概念方面,主动参与型学生的发展要优于被动参与型和消极参与型学生。  相似文献

An analogue functional analysis revealed that the problem behavior of a young child with developmental delays was maintained by positive reinforcement. A concurrent-schedule procedure was then used to vary the amount of effort required to emit mands. Results suggested that response effort can be an important variable when developing effective functional communication training programs.  相似文献

该研究通过对儿童2~4岁的抑制性发展类型与他们同陌生同伴交往特征的关系研究发现(1)在陌生情境中,稳定极端抑制儿童与陌生同伴的游戏活动的社交复杂程度是最低的.从非抑制发展到抑制的儿童在陌生情境中与稳定极端抑制的儿童没有明显差异.(2)从抑制发展到非抑制的儿童在陌生情境中的单独-被动行为是最多的;他们在介绍生日的同伴活动中的主动性是最好的;他们进行的社会性装扮游戏也是最多的.(3)稳定极端非抑制的儿童在陌生情境中与陌生同伴交往的社交复杂程度最高,他们进行的活动类型和活动频次最多,但他们可能有一些外显行为问题.  相似文献

The goal of the current study was to test the diathesis–stress and causal mediation components of the hopelessness theory of depression in third- and seventh-grade children. The procedure involved an initial assessment of depressive symptoms, hopelessness, and the 3 cognitive styles posited as vulnerability factors by hopelessness theory. The procedure also involved a series of 6 weekly follow-up assessments in which depressive symptoms, hopelessness, and the occurrence of negative events were assessed. A depressogenic attributional style interacted with negative events to predict increases in depressive symptoms in seventh-grade children but not in third-grade children. A depressogenic inferential style about consequences interacted with negative events to predict increases in depressive symptoms in both third- and seventh-grade children. Last, a depressogenic inferential style about the self interacted with negative events to predict increases in depressive symptoms in third- and seventh-grade girls but not boys. None of these interactions were mediated by hopelessness.  相似文献
