Speech‐perception‐in‐noise deficits in dyslexia

Speech perception deficits in developmental dyslexia were investigated in quiet and various noise conditions. Dyslexics exhibited clear speech perception deficits in noise but not in silence. Place‐of‐articulation was more affected than voicing or manner‐of‐articulation. Speech‐perception‐in‐noise deficits persisted when performance of dyslexics was compared to that of much younger children matched on reading age, underscoring the fundamental nature of speech‐perception‐in‐noise deficits. The deficits were not due to poor spectral or temporal resolution because dyslexics exhibited normal ‘masking release’ effects (i.e. better performance in fluctuating than in stationary noise). Moreover, speech‐perception‐in‐noise predicted significant unique variance in reading even after controlling for low‐level auditory, attentional, speech output, short‐term memory and phonological awareness processes. Finally, the presence of external noise did not seem to be a necessary condition for speech perception deficits to occur because similar deficits were obtained when speech was degraded by eliminating temporal fine‐structure cues without using external noise. In conclusion, the core deficit of dyslexics seems to be a lack of speech robustness in the presence of external or internal noise.     

Language‐specific stress perception by 9‐month‐old French and Spanish infants

During the first year of life, infants begin to have difficulties perceiving non‐native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non‐segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a language with fixed stress) have great difficulties in perceiving stress contrasts ( Dupoux, Pallier, Sebastián & Mehler, 1997 ), whereas speakers of Spanish (a language with lexically contrastive stress) perceive these contrasts as accurately as segmental contrasts. We show that language‐specific differences in the perception of stress likewise arise during the first year of life. Specifically, 9‐month‐old Spanish infants successfully distinguish between stress‐initial and stress‐final pseudo‐words, while French infants of this age show no sign of discrimination. In a second experiment using multiple tokens of a single pseudo‐word, French infants of the same age successfully discriminate between the two stress patterns, showing that they are able to perceive the acoustic correlates of stress. Their failure to discriminate stress patterns in the first experiment thus reflects an inability to process stress at an abstract, phonological level.     

Do birds of a feather universally flock together? Cultural variation in the similarity‐attraction effect

Three experiments explored the similarity‐attraction effect (SAE) among North American and Japanese samples. In all studies, North Americans showed a significantly more pronounced SAE than the Japanese. The North Americans consistently revealed a strong SAE whereas the Japanese effect was only significant in the methods with the most power. The cultural differences emerged across different methods, and for the domains of personality, activities, attitudes and demographics. The cultural difference was mediated by self‐esteem, indicating that a motivation for positive self‐views is a mechanism underlying the SAE.     

Predicting school adjustment from motor abilities in kindergarten

The present study assessed the relations between basic motor abilities in kindergarten and scholastic, social, and emotional adaptation in the transition to formal schooling. Seventy‐one five‐year‐old kindergarten children were administered a battery of standard assessments of basic motor functions. A year later, children's adjustment to school was assessed via a series of questionnaires completed by the children and their class teachers. The results indicate that in addition to the already documented association between visual–motor integration and academic achievement, other motor functions show significant predictive value to both scholastic adaptation and social and emotional adjustment to school. The results further suggest a better prediction of scholastic adaptation and level of disruptive behaviour in school when using an aggregate measure of children's ability in various motor domains than when using assessments of singular motor functions. It is concluded that good motor ability may serve as a buffer to the normative challenges presented to children in the transition to school. In contrast, poor motor ability emerges as a vulnerability factor in the transition to formal schooling. Copyright © 2007 John Wiley & Sons, Ltd.     

Do maternal stress and home environment mediate the relation between early income‐to‐need and 54‐months attentional abilities?

Using Ecological Systems Theory and stage sequential modelling procedures for detecting mediation, this study examined how early developmental contexts impact preschoolers' performances on a measure of sustained attention and impulse control. Data from 1273 European‐American and African‐American participants in the NICHD Study of Early Child Care were used to identify the potential mediators of the relation between early household income‐to‐need (INR) and 54‐month impulsivity and inattention. Exploratory analyses were also conducted to determine whether the relationships between early income, home environment, parenting stress, and the outcome variables differ for African‐American versus European‐American‐American children. We found modest support for the study hypothesis that 36‐month home environment quality mediated the INR/attention relationship. INR accounted for more home environment score variance and home environment accounted for more Impulsivity score variance for African‐American children. Home environments were related to inattention in the European‐American, but not African‐American, group. Copyright © 2007 John Wiley & Sons, Ltd.     

Women's Caregiving Careers and Retirement Financial Insecurity

Providing the essential care for children and aged relatives has immediate and long‐term financial consequences for women, particularly financial insecurity in retirement. Women's caregiving careers are examined in relationship to the impact on retirement. The need for career and retirement education and counseling aimed at women who assume caregiving roles is addressed.     

Environmental influences on reading‐related outcomes: an adoption study

Evidence from intervention studies, quantitative genetic and molecular genetic studies suggests that genetic, and to a lesser extent, shared environmental influences are important to the development of reading and related cognitive skills. The Northeast‐Northwest Collaborative Adoption Projects (N2CAP) is a sample of 241 adoptive families, containing 354 children and their adoptive parents. Negative parent outcome × child age interactions significantly predicted child outcomes, suggesting that shared environmental influences related to parent–offspring resemblance, although modest, are most salient in younger children. Additional analyses suggested that identified measures of the family environment largely accounted for these parent–offspring correlations. Copyright © 2007 John Wiley & Sons, Ltd.     

Fathers' parenting hassles and coping: associations with emotional expressiveness and their sons' socioemotional competence

The present study examined fathers' daily parenting hassles and coping strategies to (a) determine their association with fathers' emotional expressiveness and (b) predict their sons' development of socioemotional competence. Fathers of 148 preschool‐aged boys reported on their parenting hassles, coping strategies, and emotional expressiveness; mothers also reported on fathers' emotional expressiveness; and teachers reported on boys' socioemotional competence. Parenting hassles were associated with less rational, more emotional, and more avoidance coping as well as negative emotional expressiveness. More emotional and less rational coping responses were related to more negative expressiveness, whereas more rational, more emotional, and less coping were related to more positive expressiveness. Fathers' negative expressiveness was predictive of their sons being rated as more aggressive and disruptive by their teachers. In addition, fathers' parenting hassles and coping both predicted teacher ratings of their sons' aggressiveness. Implications of the findings are discussed.

关于中国心理健康服务体系建设的若干问题

从我国心理健康服务的基本模式、技术体系、服务主体、教育培训、管理监督等五个方面回顾了我国心理健康服务体系的现状。近二、三十年来,我国心理健康服务体系从无到有,发展迅速,但也存在若干亟待解决的问题:服务的技术体系不完善,心理服务的从业机构和个人良莠不齐、总体水平偏低,从业人员的教育培训、从业人员和机构的资质认证缺乏有效的监督管理机制等。目前我国的心理健康服务体系难以适应社会对心理健康服务的需求。需要立足国情,借鉴外国的成功经验并结合我国传统文化,以扎实的研究和细致的工作来完善我国的心理健康服务体系。
