Parent-Rated Anxiety Symptoms in Children with Pervasive Developmental Disorders: Frequency and Association with Core Autism Symptoms and Cognitive Functioning

Background In addition to the core symptoms, children with Pervasive Developmental Disorders (PDD) often exhibit other problem behaviors such as aggression, hyperactivity, and anxiety, which can contribute to overall impairment and, therefore, become the focus of clinical attention. Limited data are available on the prevalence of anxiety in these children. We examined frequency and correlates of parent-rated anxiety symptoms in a large sample of children with PDD. Methods The goals of this study were to examine the frequency and correlates of parent-rated anxiety symptoms in a sample of 171 medication-free children with PDD who participated in two NIH-funded medication trials. Twenty items of the Child and Adolescent Symptom Inventory (CASI) were used to measure anxiety. Results Forty three percent of the total sample met screening cut-off criteria for at least one anxiety disorder. Higher levels of anxiety on the 20-item CASI scale were associated with higher IQ, the presence of functional language use, and with higher levels of stereotyped behaviors. In children with higher IQ, anxiety was also associated with greater impairment in social reciprocity. Conclusion Anxiety is common in PDD and warrants consideration in clinical evaluation and treatment planning. This study suggests that parent ratings could be a useful source of information about anxiety symptoms in this population. Some anxiety symptoms such as phobic and social anxiety may be closer to core symptoms of PDD. Further efforts to validate tools to ascertain anxiety are needed, as are studies to empirically test approaches to treat anxiety in PDD.     

发展行为遗传学简介

发展行为遗传学是发展心理学与行为遗传学的交叉学科, 旨在探明遗传与环境对人类心理与行为发展是否存在影响, 如何产生影响, 以及该影响及其作用机制是否随年龄增长而发展变化的问题。该学科与行为遗传学在研究对象、设计和内容等方面存在不同; 开展发展行为遗传学研究需要综合运用心理测量法和行为遗传学研究方法; 未来研究应拓宽和深化候选基因与行为关联性的考察, 并着力探析基因与环境的相互作用机制。     

Attentional SNARC: there's something special about numbers (let us count the ways)

We report a study that examines whether the presentation of irrelevant, ordinal information at central fixation interacts with the allocation of attention beyond fixation. Previous research has demonstrated that number perception influences the allocation of spatial attention, such that the presentation of a spatially nonpredictive number at fixation results in attention being allocated to the left when the central number is low (e.g., 1), and attention being allocated to the right when the central number is high (e.g., 9). Here, we examine whether this attentional SNARC effect (spatial numerical association of response codes) generalizes to other ordinal sequences: letters, days, and months. Though we replicate the attentional SNARC we find that this effect is number-specific, unless participants are required to process the cue in an order-relevant fashion. This discovery of number-specificity has important implications both for the functional separation between SNARC and attention-SNARC effects, as well as lending support to recent theories regarding the specificity of a shared neural architecture between numbers and visuospatial attention.     

积极情绪影响任务转换的性别和发展特点

情绪研究中的性别和年龄因素一直是不容忽视的问题.已有研究表明,积极情绪能够提高认知的灵活性,任务转换是认知灵活性的主要成分.本研究以52名大学生3、6名高中生4、5名初中生为被试考察积极情绪影响任务转换的发展变化和性别差异.结果发现,对于女性,积极情绪促进任务转换的现象,在三个年龄段上具有发展上的稳定性;对于男性,只在初中阶段表现出此特点,在高中阶段和大学阶段,积极情绪促进任务转换的现象不再明显.     

企业员工心理契约的结构维度

用所研制的心理契约问卷,先后通过6家和4家两个企业员工样本共1088名被试的调查,对心理契约结构维度进行探讨。探索性因素分析结果表明,心理契约组织责任和员工责任均由现实责任和发展责任两个因素构成。两因素结构的结果在验证性因素分析中得到了验证。最后对心理契约结构维度的构成、内容和含义及其与西方研究结果的异同进行了讨论。     

When home is in jail: child development in Spanish penitentiary units

The quality of the educational family context of children who live with their mothers in prison (N=127, age M=16.3 months) as well as how this situation affects their level of development are analysed. The assessment of these contexts was carried out using the HOME scale. The evaluation of the children's development was carried out using the Brunet–Lézine scale. The data shows that the quality of this context is extremely low, with one of the most striking features being the low score obtained in the subscales of provision of play materials and variety of experiences. Moreover, there are significant differences in the scores that are related to the mother's level of education, ethnic origins and the type of prison where they are serving their sentences. As for the scores obtained by the children in the Brunet–Lézine scale, the data shows that their level of development is similar to that of the infant population in general although we also found that the development quotients of the children in the group with the lowest scores in the HOME scale tend to drop significantly after 18 months of age. The results are discussed taking into account the interaction of context and development under the light of the canalization hypothesis, and making some suggestions about possible ways to improve these children's life conditions.

Using High-Probability Request Sequences to Increase Journal Writing

Written expression is a key aspect of academic success. Programs to enhance writing skills often rely on a feedback loop that consists of student production (i.e., get something on paper) and teacher feedback. Unfortunately, some students fail to produce enough written product so that the teacher can give constructive feedback. The purpose of this study was to examine two methods to increase the written word production of four students with difficulties in written expression. In the verbal prompt condition, students were given verbal prompts by their teacher to resume writing in their journals after the student stopped writing for approximately one min. In the high-p request condition, the teacher asked students to write a series of three words that typically occasioned compliance prior to asking the student to resume journal writing. Both interventions were assessed within the context of verbal praise and no verbal praise. Results suggested that both interventions increased the number of words written, particularly in the verbal praise condition. However, the high-p request sequence was more efficient and produced writing behavior that was more persistent across sessions. Results are discussed within the context of the theory of behavioral momentum.
