There is now a growing body of research examining developmental dyslexia in different languages and writing systems. The phonologically transparent Persian orthography is normally transcribed with two distinct spellings, words spelled with vowels (letters) transcribed as a fixed part of the spelling (transparent) and words spelled with vowels (diacritics) omitted (opaque). This peculiarity of Persian would enable one to examine the impact of transparency, as well as the possible psychological factors associated with verbal punishment in Persian schools on the development of reading and spelling. Twenty-nine Persian children (22 male and 7 female) classified as being developmentally dyslexic (mean age 9.4, SD?=?1.4) were compared with 49 unimpaired male children (mean age 9, SD?=?1.3) on two main aspects of reading Persian opaque and transparent spellings, namely: Spelling and word naming. The results showed an expected impairment on all aspects of reading between unimpaired and children with dyslexia. However, performance of both groups of participants was impaired when performing tasks with opaque as opposed to transparent spellings. There was also a strong correlation between the recorded number of times the dyslexic child was verbally punished and the number of errors on the spelling and naming of transparent and opaque words. These results are supportive of the impact of spelling transparency, as well as psychological variables as factors in the development of reading and spelling.  相似文献

One longstanding hypothesis in the research of depression among Chinese populations is that they tend to express depressive symptoms in somatic terms, which, in turn, prevent them from seeking assistance from mental health services. This study aimed to examine the manifestation of depressive symptoms and its relationship to help‐seeking attitudes among Chinese college students. The Chinese Beck Depression Inventory‐II (BDI‐II; Beck, Steer, & Brown, 1996 ) and the Attitudes Toward Seeking Professional Psychological Help: Shortened Form (ATSPPH‐SF; Fischer & Farina, 1995 ) were administered to 1039 Chinese college students in a private university in Taiwan. Factor ratio scores analyses revealed that Chinese college students generally emphasized somatic complaints compared to cognitive‐affective complaints in expressing depressive symptoms. Probably‐depressed Chinese students (BDI‐II scores?16), however, placed significantly less emphasis on somatic symptoms than did nondepressed students. Additionally, multiple regression analyses showed that while Chinese students with elevated BDI‐II scores were less likely to seek professional psychological help, neither somatic nor cognitive‐affective symptoms were correlated with their attitudes toward seeking and avoiding professional psychological help. These findings seem to run counter to the common assumption that Chinese people tend to express depression in somatic terms and that somatic complaints help to explain their reluctance to seek professional psychological assistance. The current results suggest that Chinese students with elevated depressive symptoms readily acknowledged and expressed cognitive‐affective symptoms of depression and they were likely to distance themselves from professional psychological help. However, somatic symptoms did not explain their reluctance to utilize mental health services.  相似文献

This study uses a multitrait, multimethod (MTMM) approach to investigate the genetic and environmental etiologies of childhood deviant peer affiliation (DPA) and problem behavior (PROB). The variability of genetic and environmental estimates by agent and method is also examined. A total of 77 monozygotic and 72 dizygotic twin pairs and each twin's close friend were assessed. The informants included parents, teachers, and twins, and the methods involved questionnaire reports and coder ratings of videotaped dyadic interactions between each twin and their close friend. Twin intraclass correlations and univariate models attributed DPA and PROB to genetic, and shared and nonshared environmental effects. Parameter estimates differed by rater and method, however. Results accentuate the imperative to attend to method effects inherent in MTMM behavioral geneticresearch.  相似文献

: Statistically, women, particularly pregnant women and new mothers, are at heightened risk for depression. The present review describes the current state of the research linking maternal depressed mood and children's cognitive and language development. Exposure to maternal depressive symptoms, whether during the prenatal period, postpartum period, or chronically, has been found to increase children's risk for later cognitive and language difficulties. The present review considers both the timing of maternal depression and the chronicity of mothers' depression on children's risk for cognitive and language delays. Infancy is frequently identified as a sensitive period in which environmental stimulation has the potential to substantially influence children's cognitive and language development. However, children's exposure to chronic maternal depression seems to be associated with more problematic outcomes for children, perhaps because depression interferes with mothers' ability to respond sensitively and consistently over time. Consistent with this expectation, interventions targeting parenting practices of depressed mothers have been found to increase children's cognitive competence during early childhood. The current review provides a synthesis of the current state of the field regarding the association between maternal depression and children's cognitive and language development during early childhood.  相似文献
