Impacts of cognitive flexibility on central word identification: evidence from poor comprehenders' discourse comprehension of first graders with ADHD.

Cognitive flexibility (CF) is an executive function component related to the ability to flexibly shift amongst multiple incompatible perspectives or descriptions of an object task. However, whether CF enhances the narrative discourse comprehension of students with attention-deficit hyperactivity disorder (ADHD) during surface semantic meaning identification remains unclear. This study aimed to examine the impacts of CF on central word (CW) identification amongst primary school students with ADHD and reading comprehension difficulties (i.e. scores in the ≤ 25th percentile of discourse comprehension but with adequate decoding skills and average decoding performance score within one standard deviation). In addition, the association of CF with CW identification performance, when the CW was located in either the first or second half of sentences, was tested with and without the interference of playing music. This study recruited 104 low-CF and 103 high-CF first grade students with ADHD and reading difficulties. Participants received measures of nonverbal intelligence, working memory, Chinese receptive vocabulary, Chinese word reading, CF and a music preference questionnaire. Additionally, participants completed the entire CW identification experiment (about 7 min) individually in a silent classroom located within the school campus. After controlling nonverbal intelligence, working memory, music preference, Chinese receptive vocabulary and Chinese word reading, the results showed that high-CF students had similar poetry discourse comprehension performance with low-CF students when the CWs were at the second half of a sentence. Moreover, high-CF students showed significantly better performance than low-CF students when the CWs were at the first half of the poetry sentences in both conditions with and without music, especially if the poetry sentence structure was more complicated than the typical 'subject-verb-object' sequence. All students with ADHD performed significantly worse in poetry discourse comprehension with music interference than without it. The results highlight the importance of CF in poetry discourse comprehension tasks, particularly when a poetry sentence uses a non-typical structure format. The possible effects of CF on poetry discourse comprehension are also discussed.

Longitudinal Relationship between Bullying Victimization and Non-Suicidal Self-Injury among Chinese Adolescents: The Buffering Roles of Gratitude and Parental Autonomy Support.

Drawing on the resilience-oriented socioecological framework, the current study contributes to scarce scholarship by exploring intrapersonal (i.e., gratitude) and interpersonal (i.e., parental autonomy support) factors in the longitudinal association between bullying victimization and adolescent non-suicidal self-injury (NSSI). Participants were 238 Chinese adolescents (Mage at Time 1 (T1) = 13.45 years; 106 girls and 132 boys) based on a two-wave prospective design with data spanning one year. At T1, adolescents self-rated all study variables, and at Time 2 (T2), youth again reported their NSSI. The results showed a significant main effect (b = 0.12, SE = 0.05, p = 0.04), indicating that bullying victimization was positively related to T2 NSSI one year later, even controlling for T1 NSSI. Moderation analyses further indicated that parental autonomy support buffered against the positive association between bullying victimization and T2 NSSI, but only when adolescents experienced lower levels of gratitude. Specifically, for adolescents with lower levels of gratitude, high levels of parental autonomy support, in a compensatory way, prevented adolescents from NSSI after victimization occurred (b = -0.03, SE = 0.09, p = 0.78); by contrast, for those with higher levels of gratitude, bullying victimization was not significantly related to T2 NSSI, regardless of the levels of parental autonomy support (b = 0.07, SE = 0.04, p = 0.59 for higher parental autonomy support; b = 0.01, SE = 0.07, p = 0.93 for lower parental autonomy support). These findings suggest that gratitude and parental autonomy support, manifesting in a compensatory interaction pattern, could serve as targeted agents for breaking the vicious linkage between bullying victimization and NSSI.

Dialogic reading with attention-deficit-hyperactivity disorder (ADHD) kindergarteners: Does reading with parents or siblings enhance their language development?

Dialogic reading (DR) is an interactive reading approach that enhances the language development of children. This study aims to extend DR to the shared reading context involving children with attention-deficit-hyperactivity disorder (ADHD) and their older siblings and to examine the effects of DR with parents/siblings on the language development of Chinese children with ADHD. This study included 850 Chinese kindergarteners with ADHD and their parents/older siblings. These children were pretested on their Chinese receptive vocabulary, expressive vocabulary, character reading, listening comprehension, and reading interest and were randomly assigned to four groups, namely, dialogic reading with parents (PR-DR), dialogic reading with siblings (SR-DR), parent reading control (PR-C), and sibling reading control (SR-C). After a 12-week intervention period, they were posttested on the same measures. Results show that both DR with parents and siblings effectively enhanced language skills and reading interest in children with ADHD. In addition, those children who read with their older siblings demonstrated greater improvements in their expressive vocabulary, character reading skills, morphological awareness, phonological awareness, and reading interest yet achieved a smaller growth in their listening comprehension compared with those who read with their parents. These findings showed the positive effects of DR on the language development of children with ADHD and highlight the importance of involving siblings in home literacy activities to facilitate the language development of these children.

Behavioral and neurophysiological aspects of working memory impairment in children with dyslexia.

The present study aimed to identify behavioral and neurophysiological correlates of dyslexia which could potentially predict reading difficulty. One hundred and three Chinese children with and without dyslexia (Grade 2 or 3, 7- to 11-year-old) completed both verbal and visual working memory (n-back) tasks with concurrent EEG recording. Data of 74 children with sufficient usable EEG data are reported here. Overall, the typically developing control group (N = 28) responded significantly faster and more accurately than the group with dyslexia (N = 46), in both types of tasks. Group differences were also found in EEG band power in the retention phase of the tasks. Moreover, forward stepwise logistic regression demonstrated that both behavioral and neurophysiological measures predicted reading difficulty uniquely. Dyslexia was associated with higher frontal midline theta activity and reduced upper-alpha power in the posterior region. This finding is discussed in relation to the neural efficiency hypothesis. Whether these behavioral and neurophysiological patterns can longitudinally predict later reading development among preliterate children requires further investigation.

Children With Chinese Dyslexia Acquiring English Literacy: Interaction Between Cognitive Subtypes of Dyslexia and Orthographies.

This study investigated the impact of Chinese dyslexia subtypes on English literacy skills (i.e., reading fluency and dictation) in Hong Kong children. Eighty-four Cantonese-speaking children officially diagnosed with dyslexia (Mage = 103 months) and 48 age-matched typically developing (TD) children were tested. Cluster analysis with performances on Chinese syllable awareness (CSA), Chinese phonemic awareness (CPA), Chinese phonological memory (CPM), Chinese orthographic awareness (COA), and matrix reasoning (MR) yielded three cognitive subtypes: the phonological deficit (PD) subtype, the orthographic deficit (OD) subtype, and the global deficit (GD) subtype. After controlling for English language experience, age, and gender, all three dyslexia subtype groups performed significantly worse in English word reading fluency and dictation than the TD children. In addition, the PD group performed worse in English PA; the OD group performed worse in English OA; and the GD group performed worse in all English skills except English PM. We compared the level of impairment in literacy between languages and dyslexia subtypes. In word reading fluency, all subtype groups experienced less impairment in English than Chinese, while the OD group showed the largest English advantage. In dictation, only the OD group showed a significant language effect favoring English. The findings suggest that different subtypes of Chinese dyslexia bear different risks for difficulties in English literacy.

Development and Validation of the Youth Career Development Competency Scale: A Study Based on Hong Kong Youth.

The challenging labor market conditions concomitant with economic globalization and advanced technology have made youth career development competency (YCDC)-young people's ability to navigate transitions through education into productive and meaningful employment-especially important. The present study aims to develop a holistic instrument to measure YCDC in Hong Kong, which has rarely been investigated in past studies. The sample consisted of 682 youths aged 15-29 years (387 male, mean age = 19.5 years) in Hong Kong. Exploratory factor analysis of the 17-item YCDC scale resulted in four competence factors-engagement, self-understanding, career and pathway exploration, and planning and career management-which accounted for 78.95% of the total variance. The final confirmatory factor analysis results indicated good model fit (CFI = 0.96, TLI = 0.95, RMSEA = 0.06, 90% CI (0.05, 0.07), SRMR = 0.03) and good factor loadings (0.78-0.91). Moreover, the results demonstrated a satisfactory internal consistency of subscales (0.89-0.93). Subgroup consistency across subsamples categorized by gender, age, and years of residence in Hong Kong was also demonstrated. In addition, correlations between the YCDC scale and subscales with other career-related and psychosocial outcomes (i.e., career outcome expectancy, career adaptability, civic engagement, social contribution, and social integration) showed good concurrent validity. The results indicated that the YCDC scale is a valid and reliable tool for measuring career development competence among youth in the Hong Kong context. Its development sheds light on how career professionals can holistically assess young people's navigation competence during their school-to-work transitions.

Mediating Effects of Emotional Support Reception and Provision on the Relationship between Group Interaction and Psychological Well-Being: A Study of Young Patients.

While it is well-established that mutual aid groups are effective in the psychological rehabilitation of vulnerable individuals, few studies have thoroughly investigated the dynamic mechanism of how psychological well-being improves through mutual aid groups of young patients with chronic health conditions. In connection with several existing theories (i.e., the helper therapy principle, equity theory, the norm of reciprocity, and the concept of communal relationships), this study aims to: (1) evaluate whether emotional support exchanges (i.e., emotional support reception and provision) mediate the relationship between group interaction and psychological well-being; and (2) compare three potential underlying mechanisms-the mediating role of emotional support provision, equitable reciprocity (i.e., a balance of receiving and providing emotional support, where no party over-benefits or under-benefits), and sequential reciprocity (i.e., repaying the helper or a third party in the future after receiving help)-through a path analysis model. A stratified random sampling procedure with chronic health conditions as the stratifying criterion was used to recruit 391 individuals aged 12-45 years from mutual aid groups in Hong Kong, who completed both the baseline and follow-up surveys over a 12-month interval. The results of the path model revealed significant mediating roles of emotional support provision and sequential reciprocity, not equitable reciprocity. The present study offers theoretical and practical implications for promoting the psychological well-being of young patients with chronic health conditions.

Remediation of a phonological representation deficit in Chinese children with dyslexia: A comparison between metalinguistic training and working memory training.

A form-preparation task in the language production field was adopted to examine output phonological representations in Chinese dyslexia and their susceptibility to training. Forty-one Chinese children with dyslexia (7-11 years old) and 36 chronological age controls completed this task. The controls demonstrated a marginally significant syllable facilitation effect (d = -0.13), indicating their use of syllable-sized phonological representations during speech production, while the group with dyslexia showed a significantly different pattern (d = 0.04), opposite to the direction of a facilitation effect. The children with dyslexia were then randomly assigned to either metalinguistic training (N = 22) or working memory training (N = 19). Only the metalinguistic training subgroup demonstrated a significant syllable facilitation effect afterward (metalinguistic: d = -0.13; working memory: d = -0.01). The results suggest the presence of a phonological representation deficit at the syllable level in Chinese dyslexia and its possible remediation by metalinguistic training. Such a phonological deficit in readers of a logographic script strongly supports the impaired phonological representation view of developmental dyslexia.

Developmental Changes in the Relationship Between Character Reading Ability and Orthographic Awareness in Chinese.

The present study examined developmental changes, over a 6-year period, in the relationship between character reading ability and orthographic awareness in Chinese from the first year of kindergarten to the third year of primary school in two separate samples: the kindergarten sample of 96 children was assessed three times in the first, second, and third years of kindergarten (K1, K2, K3) with 12-month intervals. The primary school sample of 204 children was assessed four times in the first and second semesters of grade 1 (P1-S1; P1-S2), first semester of grade 2 (P2-S1) and grade 3 (P3-S1), with the first three waves at 6-month intervals and the final wave at 12-month interval. Cross-lagged path analysis showed three developmental stages of the relationship between Chinese character reading and orthographic awareness. At stage 1, reading ability in K1 and K2 predicted subsequent orthographic awareness in K2 and K3. At stage 2, there was a bidirectional relationship between character reading and orthographic awareness from P1-S1 to P1-S2. At stage 3, orthographic awareness at P1-S2 and P2-S1 predicted subsequent character reading ability at P2-S1 and P3-S1, but the prediction from reading to orthographic awareness vanished at this stage. The results depict a full developmental picture of the changed relationship between Chinese character reading and orthographic awareness over time. Beginning readers demonstrated impressive abilities in discovering or extracting orthographic regularities with increased reading ability.

Genomewide scan for linkage reveals evidence of several susceptibility loci for alopecia areata.

Alopecia areata (AA) is a genetically determined, immune-mediated disorder of the hair follicle that affects 1%-2% of the U.S. population. It is defined by a spectrum of severity that ranges from patchy localized hair loss on the scalp to the complete absence of hair everywhere on the body. In an effort to define the genetic basis of AA, we performed a genomewide search for linkage in 20 families with AA consisting of 102 affected and 118 unaffected individuals from the United States and Israel. Our analysis revealed evidence of at least four susceptibility loci on chromosomes 6, 10, 16 and 18, by use of several different statistical approaches. Fine-mapping analysis with additional families yielded a maximum multipoint LOD score of 3.93 on chromosome 18, a two-point affected sib pair (ASP) LOD score of 3.11 on chromosome 16, several ASP LOD scores >2.00 on chromosome 6q, and a haplotype-based relative risk LOD of 2.00 on chromosome 6p (in the major histocompatibility complex locus). Our findings confirm previous studies of association of the human leukocyte antigen locus with human AA, as well as the C3H-HeJ mouse model for AA. Interestingly, the major loci on chromosomes 16 and 18 coincide with loci for psoriasis reported elsewhere. These results suggest that these regions may harbor gene(s) involved in a number of different skin and hair disorders.

Dominant and recessive deafness caused by mutations of a novel gene, TMC1, required for cochlear hair-cell function.

Positional cloning of hereditary deafness genes is a direct approach to identify molecules and mechanisms underlying auditory function. Here we report a locus for dominant deafness, DFNA36, which maps to human chromosome 9q13-21 in a region overlapping the DFNB7/B11 locus for recessive deafness. We identified eight mutations in a new gene, transmembrane cochlear-expressed gene 1 (TMC1), in a DFNA36 family and eleven DFNB7/B11 families. We detected a 1.6-kb genomic deletion encompassing exon 14 of Tmc1 in the recessive deafness (dn) mouse mutant, which lacks auditory responses and has hair-cell degeneration. TMC1 and TMC2 on chromosome 20p13 are members of a gene family predicted to encode transmembrane proteins. Tmc1 mRNA is expressed in hair cells of the postnatal mouse cochlea and vestibular end organs and is required for normal function of cochlear hair cells.
