小学生人格类型及发展特点研究

该文在以往中国儿童人格结构研究基础上,以问卷调查(N=1316)方式,将层次聚类和迭代聚类两种方法结合起来,同时采用理论分析等方法最终确定我国小学生的人格类型包括认可型、矛盾型、拒绝型及中间型四类。其中认可型属积极人格类型,矛盾型和拒绝型属消极人格类型。研究表明,认可型女孩的人数比重明显高于男孩,而拒绝型男孩的人数比重明显高于女孩。此外,矛盾型女孩的人数比重较明显地高于男孩。     

儿童和青少年信息加工速度发展函数的研究

选择７—１９岁的被试１４０名,对三种不同任务进行操作。结果表明,在句图匹配任务中,儿童反应时是青年反应时的函数,指数函数能较好的描述这种共同的发展变化趋势,但在字母匹配任务中,这种线性关系较差;随着年龄的变化,信息加工速度的下降速率是根据不同的加工任务变化的,简单任务（选择反应和字母匹配）下降速度快,复杂任务（句图匹配）下降速度慢     

Learning to divide the labor: an account of deficits in light and heavy verb production

Theories of sentence production that involve a convergence of activation from conceptual‐semantic and syntactic‐sequential units inspired a connectionist model that was trained to produce simple sentences. The model used a learning algorithm that resulted in a sharing of responsibility (or “division of labor”) between syntactic and semantic inputs for lexical activation according to their predictive power. Semantically rich, or “heavy”, verbs in the model came to rely on semantic cues more than on syntactic cues, whereas semantically impoverished, or “light”, verbs relied more on syntactic cues. When the syntactic and semantic inputs were lesioned, the model exhibited patterns of production characteristic of agrammatic and anomic aphasic patients, respectively. Anomic models tended to lose the ability to retrieve heavy verbs, whereas agrammatic models were more impaired in retrieving light verbs. These results obtained in both sentence production and single‐word naming simulations. Moreover, simulated agrammatic lexical retrieval was more impaired overall in sentences than in single‐word tasks, in agreement with the literature. The results provide a demonstration of the division‐of‐labor principle, as well as general support for the claim that connectionist learning principles can contribute to the understanding of non‐transparent neuropsychological dissociations.     

Life skills instruction for children with developmental disabilities

The Preschool Life Skills program is an intervention package designed to teach functional skills to prevent problem behavior in typically developing children. The purpose of the current study was to evaluate the effects of the instructional package (renamed “Life Skills”) with children with developmental disabilities. The program involved teaching 12 life skills to nine participants across four instructional units. The units were instruction following, functional communication, tolerance of denial and delay, and friendship skills. Teachers provided instruction through a three-tiered instructional approach, starting with class-wide instruction followed by small group and one-to-one instruction as necessary. We extended previous research by using visual prompts during all three tiers and progressively increasing intertrial intervals during one-to-one instruction. Results indicated that the intervention led to skill acquisition with all nine participants. The skills maintained 4 weeks after instruction ended.     

The Early Childhood Irritability-Related Impairment Interview (E-CRI): A Novel Method for Assessing Young Children’s Developmentally Impairing Irritability

Irritability is a substrate of more than one dozen clinical syndromes. Thus, identifying when it is atypical and interfering with functioning is crucial to the prevention of mental disorder in the earliest phase of the clinical sequence. Advances in developmentally based measurement of irritability have enabled differentiation of normative irritable mood and tantrums from indicators of concern, beginning in infancy. However, developmentally sensitive assessments of irritability-related impairment are lacking. We introduce the Early Childhood Irritability-Related Impairment Interview (E-CRI), which assesses impairment associated with irritable mood and tantrums across contexts. Reliability and validity are established across two independent samples varied by developmental period: the Emotional Growth preschool sample (EmoGrow; N = 151, M = 4.82 years) and the When to Worry infant/toddler sample (W2W; N = 330, M = 14 months). We generated a well-fitting two-factor E-CRI model, with tantrum- and irritable mood-related impairment factors. The E-CRI exhibited good interrater, test–retest, and longitudinal reliability. Construct and clinical validity were also demonstrated. In both samples, E-CRI factors showed association to internalizing and externalizing problems, and to caregiver-reported concern in W2W. Tantrum-related impairment demonstrated stronger and more consistent explanatory value across outcomes, while mood-related impairment added explanatory utility for internalizing problems. The E-CRI also showed incremental utility beyond variance explained by the Family Life Impairment Scale (FLIS) survey indicator of developmental impairment. The E-CRI holds promise as an indicator of impairment to inform identification of typical versus atypical patterns reflecting early emerging irritability-related syndromes in the initial phase of the clinical sequence.

Timing of Onset and Correlates of Severe Conduct Problems in Adjudicated Girls and Boys

An influential model for explaining the development of conduct disorder (CD) in boys proposed that there are two distinct trajectories through which boys develop CD that differ on the timing of onset, correlates, and outcome. In this study, the applicability of this two trajectory approach to the development of CD in girls was tested. Participants were 72 adolescents (mean = 15.17 years of age; SD = 1.32) who were adjudicated for serious patterns of illegal behavior in a secure detention facility, nearly all of whom (94.4%) met criteria for a diagnosis of CD. Based on a combination of youth self-report and file review, boys in the sample were fairly evenly split between a childhood-onset to their CD symptoms and an adolescent-onset to their symptoms. In contrast, girls more uniformly exhibited an adolescent-onset to their severe antisocial behavior. Despite this later age of onset, the antisocial girls tended to resemble the childhood-onset boys on personality traits such as showing problems of impulse control and showing combination of both a callous and unemotional interpersonal style and poor impulse control. These findings suggest modifications of or alternatives to the two-trajectory model may be needed to explain the development of CD in girls.
