RESUMO

BACKGROUND: The Children's Response Styles Questionnaire (CRSQ) is a widely-adopted inventory that assesses response styles in youths. It is useful in examining how coping styles (particularly rumination) may relate to depressive vulnerability in youths. Despite its utility, little is known about its applicability in non-Western cultures and CRSQ has not been evaluated using current psychometric methods including item response theory (IRT). The present study assessed the properties using IRT methods in a Chinese youth sample. METHODS: Students in Grades 4-6 were recruited from seven public primary schools in Hong Kong, and a total of 581 children (280 boys and 301 girls) between 8 and 14 years of age participated in the study. A Chinese version of CRSQ was administered to them in groups at school after receiving written parental consent as well as students' assent. RESULTS: Confirmatory factor analysis revealed a two-factor structure that was comparable to that identified in Western samples, namely, the rumination and distraction/problem-solving subscales. IRT analysis suggested that items varied in levels of item discrimination and item severity, and in precision/usefulness for assessing the underlying latent trait levels. Test information analysis indicated that rumination subscale was more useful than the distraction and problem-solving subscale in assessing the latent trait over a broader range of levels. For gender-based Differential Item Functioning (DIF) analysis, item 1 "When I am sad, I think about how alone I feel" was found to exhibit higher discriminating power for girls than boys. CONCLUSIONS: The study presents the first attempt to examine CRSQ item properties using IRT analysis and supports its validity beyond the Western cultures. The factor structure of CRSQ was found to be comparable to the West in our Chinese sample. Differential Item Functioning (DIF) evaluation suggested all but one item in the rumination subscale of the CRSQ apply equally well to both boys and girls.

RESUMO

To fully acquire a language, especially its phonology, children need linguistic input from native speakers early on. When interaction with native speakers is not always possible - e.g. for children learning a second language that is not the societal language - audios are commonly used as an affordable substitute. But does such non-interactive input work? Two experiments evaluated the usefulness of audio storybooks in acquiring a more native-like second-language accent. Young children, first- and second-graders in Hong Kong whose native language was Cantonese Chinese, were given take-home listening assignments in a second language, either English or Putonghua Chinese. Accent ratings of the children's story reading revealed measurable benefits of non-interactive input from native speakers. The benefits were far more robust for Putonghua than English. Implications for second-language accent acquisition are discussed.

RESUMO

Holistic processing and left-side bias are both behavioral markers of expert face recognition. By contrast, expert recognition of characters in Chinese orthography involves left-side bias but reduced holistic processing, although faces and Chinese characters share many visual properties. Here, we examined whether this reduction in holistic processing of Chinese characters can be better explained by writing experience than by reading experience. Compared with Chinese nonreaders, Chinese readers who had limited writing experience showed increased holistic processing, whereas Chinese readers who could write characters fluently showed reduced holistic processing. This result suggests that writing and sensorimotor experience can modulate holistic-processing effects and that the reduced holistic processing observed in expert Chinese readers may depend mostly on writing experience. However, both expert writers and writers with limited experience showed similarly stronger left-side bias than novices did in processing mirror-symmetric Chinese characters; left-side bias may therefore be a robust expertise marker for object recognition that is uninfluenced by sensorimotor experience.

RESUMO

Early attention bias to threat-related negative emotions may lead children to overestimate dangers in social situations. This study examined its emergence and how it might develop in tandem with a known predictor namely temperamental shyness for toddlers' fear of strangers in 168 Chinese toddlers. Measurable individual differences in such attention bias to fearful faces were found and remained stable from age 12 to 18 months. When shown photos of paired happy versus fearful or happy versus angry faces, toddlers initially gazed more and had longer initial fixation and total fixation at fearful faces compared with happy faces consistently. However, they initially gazed more at happy faces compared with angry faces consistently and had a longer total fixation at angry faces only at 18 months. Stranger anxiety at 12 months predicted attention bias to fearful faces at 18 months. Temperamentally shyer 12-month-olds went on to show stronger attention bias to fearful faces at 18 months, and their fear of strangers also increased more from 12 to 18 months. Together with prior research suggesting attention bias to angry or fearful faces foretelling social anxiety, the present findings point to likely positive feedback loops among attention bias to fearful faces, temperamental shyness, and stranger anxiety in early childhood.

RESUMO

Holistic processing has been identified as an expertise marker of face and object recognition. By contrast, reduced holistic processing is purportedly an expertise marker in recognising orthographic characters in Chinese. Does holistic processing increase or decrease in expertise development? Is orthographic recognition a domain-specific exception to all other kinds of recognition (e.g. face and objects)? In two studies, we examined the developmental trend of holistic processing in Chinese character recognition in Chinese and non-Chinese children, and its relationship with literacy abilities: Chinese first graders-with emergent Chinese literacy acquired in kindergarten-showed increased holistic processing perhaps as an inchoate expertise marker when compared with kindergartners and non-Chinese first graders; however, the holistic processing effect was reduced in higher-grade Chinese children. These results suggest a non-monotonic inverted U-shape trend of holistic processing in visual expertise development: An increase in holistic processing due to initial reading experience followed by a decrease in holistic processing due to literacy enhancement. This result marks the development of holistic and analytic processing skills, both of which can be essential for mastering visual recognition. This study is the first to investigate the developmental trend of holistic processing in Chinese character recognition using the composite paradigm.

RESUMO

LAY ABSTRACT: The 13-item Classroom Observation Scale is an autism spectrum disorder screening tool for teachers and non-clinically trained observers to make real-time observation of children's peer interaction (or the lack thereof) in regular preschool classrooms. The Classroom Observation Scale was originally developed in English and validated with ethnically diverse preschoolers at English-speaking international schools serving families from middle to middle-upper socioeconomic backgrounds in Hong Kong. These private schools can usually afford a higher teacher-student ratio, which is not typical for most preschools. This study, therefore, investigated whether the Classroom Observation Scale is ecologically valid when used by Chinese teachers with teacher-student ratios typically found in less-resourced preschools. We found that the Classroom Observation Scale reliably helped observers with little or no clinical training-research assistants with just a few hours of Classroom Observation Scale training and preschool teachers with an hour of briefing-to identify children in their first year of Chinese-language preschool who were more likely than their peers to have autism spectrum disorder. Reliability estimates of Classroom Observation Scale-Teacher and Classroom Observation Scale-Researcher in this study were comparable to those for the original English Classroom Observation Scale. Our results provided further evidence on the versatility and ecological validity of the Classroom Observation Scale for use by preschool teachers and non-clinically trained observers in the early identification of children with autism spectrum disorder in community settings.

RESUMO

This study examined how mood states affect nursing students' performance on a treatment procedure consisting of a novel combination of familiar clinical steps. Thirty third-year and fourth-year nursing students were first taught the procedure and then given both an anxious-mood and a calm-mood induction in a randomly assigned counterbalanced order. Anxiety was induced by showing a video of interviews with frontline nurses and doctors during the severe acute respiratory syndrome epidemic in Hong Kong, China; calmness was induced by a video of a nursing student's pleasant orientation to a clinical placement site. Nursing students were significantly less proficient in performing the newly acquired procedure after an anxious-mood induction (focused on occupational risks) than after a calm-mood induction. Therefore, managing clinical training site anxiety among nursing students may help to optimize learning and clinical performance.

RESUMO

LAY ABSTRACT: With professional training and regular opportunities to observe children interacting with their peers, preschool teachers are in a good position to notice children's autism spectrum disorder symptomatology. Yet even when a preschool teacher suspects that a child may have autism spectrum disorder, fear of false alarm may hold the teacher back from alerting the parents, let alone suggesting them to consider clinical assessment for the child. A valid and convenient screening tool can help preschool teachers make more informed and hence more confident judgment. We set out to develop a screening tool that capitalizes on peer interaction as a naturalistic "stress test" to identify children more likely than their peers to have autism spectrum disorder. A total of 304 3- to 4-year-olds were observed at school with an 84-item preliminary checklist; data-driven item reduction yielded a 13-item Classroom Observation Scale. The Classroom Observation Scale scores correlated significantly with Autism Diagnostic Observation Schedule-2 scores. To validate the scale, another 322 2- to 4-year-olds were screened using the Classroom Observation Scale. The screen-positive children and randomly selected typically developing peers were assessed for autism spectrum disorder 1.5 years later. The Classroom Observation Scale as used by teachers and researchers near preschool onset predicted autism spectrum disorder diagnoses 1.5 years later. This user-friendly 13-item Classroom Observation Scale enables teachers and healthcare workers with little or no clinical training to identify, with reliable and valid results, preschoolers more likely than their peers to have autism spectrum disorder.

RESUMO

A cross-cultural comparison between U.S. and Hong Kong preschoolers examined factors responsible for young children's analogical reasoning errors. On a scene analogy task, both groups had adequate prerequisite knowledge of the key relations, were the same age, and showed similar baseline performance, yet Chinese children outperformed U.S. children on more relationally complex problems. Children from both groups were highly susceptible to choosing a perceptual or semantic distractor during reasoning when one was present. Taken together, these similarities and differences suggest that (a) cultural differences can facilitate better knowledge representations by allowing more efficient processing of relationally complex problems and (b) inhibitory control is an important factor in explaining the development of children's analogical reasoning.

RESUMO

It is as yet unclear whether the benefits of early linguistic experiences can be maintained without at least some minimal continued exposure to the language. This study compared 12 adults adopted from Korea to the US as young children (all but one prior to age one year) to 13 participants who had no prior exposure to Korean to examine whether relearning can aid in accessing early childhood language memory. All 25 participants were recruited and tested during the second week of first-semester college Korean language classes. They completed a language background questionnaire and interview, a childhood slang task and a Korean phoneme identification task. Results revealed an advantage for adoptee participants in identifying some Korean phonemes, suggesting that some components of early childhood language memory can remain intact despite many years of disuse, and that relearning a language can help in accessing such a memory.

RESUMO

OBJECTIVES: To promote gender diversity and equity in higher education, Athena Scientific Women's Academic Network (SWAN) supports and recognises higher education institutions (HEI) in advancing the careers of women through charter commitment, awards, training and advocacy since 2005. Most evaluation studies, however, are based on qualitative assessments. This study sought to (1) examine the relationship between Athena SWAN accreditation/awards in the UK and gender diversity of leaders and senior academics using quantitative data from 2012/2013 to 2016/2017, and (2) explore the associations between Athena SWAN awards and university performance as measured by overall scores in global ranking systems. DESIGN: Retrospective cohort study based on the UK HEIs. SETTING: Higher education sector in the UK provided by the Higher Education Statistics Agency. PARTICIPANTS: 148 HEIs who provided employment data on female-to-male ratios (55% complete data) for each academic year between 2012/2013 and 2016/2017. PRIMARY AND SECONDARY OUTCOME MEASURES: Gender diversity, defined as female representation rates of positions in managerial leadership (eg, heads of institutions, department heads) and professors. The Quacquarelli Symonds (QS) World University Rankings scores, an indicator of research, teaching, employability and internationalisation, were collected to measure university performance. RESULTS: Gender diversity of managerial leaders and non-managerial professors at all levels of Athena SWAN status has improved over the 5 years. Linear mixed effects models identified that Athena SWAN awardees had lower female representation than non-awardees in managerial leadership positions (p<0.05), while the gap was narrowed among Silver awardees over time. Athena SWAN Charter members had increasingly higher female representation than those not in the Charter (p<0.05). Silver-award institutions ranked higher in QS rankings than Bronze-award institutions (ß=11.80, p<0.05). CONCLUSIONS: There are overall rising trends in gender diversity from 2012/2013 to 2016/2017. Athena SWAN members showed greater and faster growth in female representations. Silver awardees had greater university performance than Bronze awardees.

RESUMO

Health education can offer a valuable window onto conceptual and behavioral change. In Study 1, we mapped out 3rd-grade Chinese children's beliefs about causes of colds and flu and ways they can be prevented. We also explored older adults' beliefs as a possible source of the children's ideas. In Study 2, we gave 3rd- and 4th-grade Chinese children either a conventional cold/flu education program or an experimental "Think Biology" program that focused on a biological causal mechanism for cold/flu transmission. The "Think Biology" program led children to reason about cold/flu causation and prevention more scientifically than the conventional program, and their reasoning abilities dovetailed with their mastery of the causal mechanism. Study 3, a modified replication of Study 2, found useful behavioral change as well as conceptual change among children who received the "Think Biology" program and documented coherence among knowledge enrichment, conceptual change, and behavioral change.

RESUMO

Patients' perceived satisfaction is a key performance index of the quality health care service. Good communication has been found to increase patient's perceived satisfaction. The purpose of this study was to examine the impact of the prominent themes arising from clinician-patient conversations on the caregiver's perceived quality of communication during paediatric dental visits. 162 video recordings of clinical dental consultations for 62 cases attending the Paediatric Dentistry Clinic of The Prince Philip Dental Hospital in Hong Kong were captured and transcribed. The patients' demographic information and the caregiver's perceived quality of communication with the clinicians were recorded using the 16-item Dental Patient Feedback on Consultation skills questionnaires. Visual text analytics (Leximancer™) indicated five prominent themes 'disease / treatment', 'treatment procedure related instructions', 'preparation for examination', 'positive reinforcement / reassurance', and 'family / social history' from the clinician-patient conversation of the recorded videos, with 60.2% of the total variance in concept words in this study explained through principal components analysis. Significant variation in perceived quality of communication was noted in five variables regarding the prominent theme 'Positive reinforcement / reassurance': 'number of related words' (p = 0.002), 'number of related utterances' (p = 0.001), 'percentage of the related words in total number of words' (p = 0.005), 'percentage of the related utterances in total number of utterances' (p = 0.035) and 'percentage of time spent in total time duration' (p = 0.023). Clinicians were perceived to be more patient-centered and empathetic if a larger proportion of their conversation showed positive reinforcement and reassurance via using related key words. Care-giver's involvement, such as clinicians' mention of the parent, was also seen as critical to perceptions of quality clinical experience. The study reveals the potential of the application of visual text analytics software in clinical consultations with implications for professional development regarding clinicians' communication skills for improving patients' clinical experiences and treatment satisfaction.

RESUMO

While early language experience seems crucial for mastering phonology, it remains unclear whether there are lasting benefits of speaking a language regularly during childhood if the quantity and quality of speaking drop dramatically after childhood. This study explored the accessibility of early childhood language memory. Specifically, it compared perception and production of Korean speech sounds by childhood speakers who had spoken Korean regularly for a few years during childhood to those of two other groups: (1) childhood hearers who had heard Korean regularly during childhood but had spoken Korean minimally, if at all; and (2) novice learners. All three groups were enrolled in first-year college Korean language classes. Childhood speakers were also compared to native speakers of Korean to see how native-like they were. The results revealed measurable long-term benefits of childhood speaking experience, underscoring the importance of early language experience, even if such experience diminishes dramatically beyond childhood.

RESUMO

This study evaluated the psychometric properties of a widely used self-report anxiety scale-the Spence Children's Anxiety Scale (SCAS) and the associated parent-report version (PSCAS)-in a Hong Kong Chinese community sample. While good psychometric properties of SCAS and PSCAS had been documented in Western cultural contexts (e.g., Australia), no systematic psychometric evaluation of the Chinese-translated SCAS and PSCAS has been published. In this study, psychometric properties of SCAS and PSCAS were examined with respect to four criteria: (a) factor structure, (b) descriptive statistics, (c) convergent validity with an anxiety cognition measure, and (d) internal consistency. Psychometric properties of SCAS and PSCAS for a Chinese community sample were found to be highly comparable with those published on Australian samples, thus providing a solid conceptual foundation for use of the Chinese version of SCAS and PSCAS.

RESUMO

This study evaluated the effectiveness of cognitive-behavioral treatment for childhood anxiety in a community clinic setting in Hong Kong, China. Forty-five clinically-referred children (age 6-11 years) were randomly assigned to either a cognitive-behavioral treatment program or a waitlist-control condition. Children in the treatment condition showed significant reduction in anxiety symptoms-both statistically and clinically-whereas children in the waitlist condition did not. After the waitlist period was over, the control group also received the treatment program and showed a similar reduction in symptoms. For the full sample of 45 children, the effectiveness of the intervention was significant immediately after treatment and in 3- and 6-month follow-ups. In addition, children's anxiety cognition and their ability to cope with anxiety-provoking situations fully mediated the treatment gains. These results offer empirical support for cognitive-behavioral treatment programs in a non-Western cultural context and plausible mediators for how cognitive-behavioral therapy works.

RESUMO

Childhood experience with a language seems to help adult learners speak it with a more native-like accent. Can analogous benefits be found beyond phonology? This study focused on adult learners of Spanish who had spoken Spanish as their native language before age 7 and only minimally, if at all, thereafter until they began to re-learn Spanish around age 14 years. They were compared with native speakers, childhood overhearers, and typical late-second-language (L2)-learners of Spanish. Both childhood speakers and overhearers spoke Spanish with a more native-like accent than typical late-L2-learners. On grammar measures, childhood speakers-although far from native-like-reliably outperformed childhood overhearers as well as typical late-L2-learners. These results suggest that while simply overhearing a language during childhood could help adult learners speak it with a more native-like phonology, speaking a language regularly during childhood could help re-learners use it with more native-like grammar as well as phonology.

RESUMO

Despite its significance for understanding of language acquisition, the role of childhood language experience has been examined only in linguistic deprivation studies focusing on what cannot be learned readily beyond childhood. This study focused instead on long-term effects of what can be learned best during childhood. Our findings revealed that adults learning a language speak with a more native like accent if they overheard the language regularly during childhood than if they did not. These findings have important implications for understanding of language-learning mechanisms and heritage-language acquisition.

RESUMO

The current study assessed whether overhearing Spanish during childhood helps later Spanish pronunciation in adulthood. Our preliminary report based on a subset of the data [Au et al., Psychol. Sci. 13, 238-243 (2002)] revealed that adults who overheard Spanish during childhood had better Spanish pronunciation, but not better morphosyntax, than adult learners of Spanish who had no childhood experience with Spanish. We now present data from the full sample with additional morphosyntax and pronunciation assessments, as well as measures to help rule out possible confounding prosodic factors such as speech rate, phrasing, and stress placement. Three groups of undergraduates were compared: 15 Spanish-English bilinguals (native Spanish speakers), 15 late learners of Spanish who overheard Spanish during childhood (childhood overhearers), 15 late learners of Spanish who had no regular experience with Spanish until middle or high school (typical late L2 learners). Results confirmed a pronunciation advantage for the childhood overhearers over the typical late L2 learners on all measures: phonetic analyses (VOT and degree of lenition), accent ratings (phoneme and story production), but no benefit in morphosyntax. Importantly, the pronunciation advantage did not seem attributable to prosodic factors. These findings illustrate the specificity of overhearers' advantage to phonological production.

RESUMO

The authors examined in this study whether mothers and adolescents discussed abstinence and safer sex, and how these discussions relate to demographic characteristics. Fifty mother-adolescent dyads (25 girls and 25 boys, aged 11-15) participated in videotaped conversations about two topics: (1) dating and sexuality, and (2) AIDS/HIV. These conversations were coded for specific topics. Both discussions of abstinence and safer sex occurred relatively infrequently during both conversations, although they were more common during AIDS than sexuality conversations and more for mothers than adolescents. The two topics were related--dyads who discussed one were more likely to discuss the other. Adolescents who discussed safer sex with their mothers tended to be older, less religious and have more educated mothers than those who did not. Using observational rather than self-report measures, this study revealed that the extent to which mothers and adolescents discuss abstinence and safer sex can depend on individual (age, gender, socioeconomic status and religious involvement) and contextual (conversational topic) factors.
