The mean fundamental frequency in stutterers and nonstutterers during reading and spontaneous speech

Corresponding to the higher tension of muscles involved in speech production, a higher mean fundamental frequency should be expected in stutterers as compared to nonstutterers. It could be shown by the change scores of the mean fundamental frequency from reading to free conversation that stutterers tend to have a higher fundamental frequency during spontaneous speech.     

Interhemispheric functional relationships in auditory agnosia : An analysis of the preconditions and a conceptual model

A statistical analysis revealed the following concerning auditory agnosia. (1) Bilateral temporal lobe lesions prevailed; in a minority of cases unilateral lesions were verified. (2) The syndrome occurred as a result of repeated insults. (3) There was a statistically significant correlation between the side of the first insult and the predilective type of the syndrome, i.e., agnosia preferably for linguistic with respect to nonlinguistic material. On the basis of these results we discuss the principle of contralateral compensation and the hypothesis of lesional interference. In doing so a conceptual model of interhemispheric functional relationships is developed. We made use of a set theory-oriented interpretation of Kinsbourne's “attention-model” (M. Kinsbourne, 1970, Acta Psychologica 33, 193–201).     

Assessing Parental Satisfaction with Children’s Mental Health Services with the Youth Services Survey for Families

We assessed parent satisfaction with childrens mental health services with a new instrument: The Youth Services Survey for Families (YSSF). The Dillman method was used to administer the survey to a random sample of 1,500 parents of Medicaid youth from Kentuckys 14 community mental health centers (CMHCs). The response rate was 37% (n = 534 parents). A factor analysis of YSSF identified five parent-perceived factors: (a) Appropriateness, (b) Outcome, (c) Participation in Treatment, (d) Access, and (e) Cultural Sensitivity. About 70% of parents reported a high level of endorsement with the Appropriateness factor, but only 47% reported high levels of endorsement with the Outcome factor. Results were interpreted as providing support for the reliability of the YSSF in evaluating childrens mental health services in CMHCs.     

Relations between mental performance and reaction time: New aspects of an old problem

The relation between simple and complex reaction time and psychometrically determined mental performance was reexamined with 486 subjects of above-average intelligence. Various standardized tests measuring aspects of cognitive ability, memory and ability to concentrate were used. Simple and complex reaction times were measured using the Klebelsberg modification of the Mierke apparatus. Correlations between complex reaction time and mental performance as observed by other investigators were mostly confirmed. We found, however, the strongest and most consistent correlations with tests measuring short-term memory; ability to concentrate and spatial ability. On the other hand, tests known and shown again in this paper to load highly on Spearman's general factor g, such as verbal abilities; combinatoric thinking; abstraction; or calculation gave only trivial, and, in most cases, nonsignificant correlations with complex reaction time. We even observed a negative (though, for our data, not significant) correlation between g-loadings of subtests and their correlations with complex reaction time for the only complete standardized intelligence test used in this study, the “Intelligenz-Strukturtest (Amthauer).” Therefore, this study does not support the hypothesis that fast processing of complex information as measured by complex reaction time is the decisive component of the general factor of intelligence g.     

考试评分缺失数据的概化理论分析

考试评分缺失数据较为常见,如何有效利用现有数据进行统计分析是个关键性问题。在考试评分中,题目与评分者对试卷得分的影响不容忽视。根据概化理论原理,按考试评分规则推导出含有缺失数据双侧面交叉设计（p×i×r）方差分量估计公式,用Matlab7.0软件模拟多组缺失数据,验证此公式的有效性。结果发现：（1）推导出的公式较为可靠,估计缺失数据的方差分量偏差相对较小,即便数据缺失率达到50％以上,公式仍能对方差分量进行较为准确地估计;（2）题目数量对概化理论缺失数据方差分量的估计影响最大,评分者次之,当题目和评价者数量分别为6和5时,公式能够趋于稳定地估计;（3）学生数量对各方差分量的估计影响较小,无论是小规模考试还是大规模考试,概化理论估计缺失数据的多个方差分量结果相差不大。     

意识特性的理论框架

G．M．Edelman和唐孝威在2003年初分别发表了关于意识特性理论框架的论文和专著。通过对两位学者提出的意识特性理论进行比较后发现,他们对脑功能活动机理以及神经信息加工的动态整合过程认识竟非常相近、对意识本质理论的描述也非常吻合。他们的研究表明了脑科学研究的物理学方向：随着脑成像技术的发展,从中可以获取丰富的脑神经信息,可以从系统层面上建立表征脑复杂性的数学物理模型,辨识脑神经各部分之间的关联作用,研究脑神经信息的整合过程。

Infant withdrawal and behavior problems in urban Chinese toddlers: Roles of maternal sensitivity to infant distress and emerging delay ability

Using a longitudinal design, this study examined the associations between infant temperamental withdrawal and behavior problems during toddlerhood and tested the moderating effects of maternal sensitivity to infant distress (MSID) and toddlers’ ability to delay gratification (ADG) in urban Chinese families. Participants were 84 Chinese children (37 boys, 47 girls) and their mothers. When the infants were 6 months old (T1: infancy), their mothers reported their temperamental withdrawal, and research assistants observed and coded MSID by using a subscale of the Maternal Behavior Q-Sort during free-play interaction. When the toddlers were 1 year old (T2: early toddlerhood), their mothers reported their internalizing and externalizing problems. When the toddlers were 2 years old (T3: late toddlerhood), their mothers again reported their internalizing and externalizing problems, and their abilities of delay gratification were assessed through a laboratory-based procedure. Infant temperamental withdrawal was associated with increased internalizing problems in early toddlerhood and increased externalizing problems during middle to late toddlerhood; infants whose mothers were extremely high sensitive or low sensitive to their distress or those with late poor ability of delay gratification were at particular risk. The findings highlight the importance of matching parenting and promotion of self-control for temperamental withdrawn children's optimal development.     

Creating “Maneuvering Room”: A Grounded Theory of Language and Influence in Marriage and Family Therapy

Influence in psychotherapy has been described as a characteristic of the therapist, a characteristic of the therapeutic relationship, and a negotiated process. This study combines grounded theory and task analysis to explore language patterns in facilitating change in family therapy. Thirty-one episodes of therapy were analyzed, resulting in the emergent concept of creating maneuvering room. Therapists introduce uncertainty into clients beliefs about problems then offer new ways of defining problems by speaking from three dimensions: therapist as expert or non-expert, therapist as participant or observer, or family members experiences as similar or different. The findings of this study support a possible common factor in family therapy.
