Home Literacy Environment and Phonological Awareness in Preschool Children: Differential Effects for Rhyme and Phoneme Awareness

The literature to date suggests that the best predictor of early reading ability, phonological awareness, appears to be associated with the acquisition of letter-sound and vocabulary knowledge and with the development of well-defined phonological representations. It further suggests that at least some aspects of phonological awareness critically depend upon literacy exposure. In this study of 4- to 6-year-olds, we examine whether aspects of the home literacy environment are differentially associated with phonological awareness. Parental responses to a questionnaire about the home literacy environment are compared to children\u27s awareness of rhyme and phonemes, as well as to their vocabulary, letter knowledge, and performance on measures of phonological strength (nonword repetition, rapid naming skill, phonological distinctness, and auditory discrimination). The results showed that a teaching focus in the home literacy environment and exposure to reading-related media are directly associated with phoneme awareness and indirectly associated via letter knowledge and vocabulary. Exposure to reading-related media and parents\u27 active involvement in children\u27s literature were also directly and indirectly linked with rhyme awareness skills via their association with letter and vocabulary knowledge

Effects of Onset Density in Preschool Children: Implications for Development of Phonological Awareness and Phonological Representation

Neighborhood density influences adult performance on several worked processing tasks. Some studies show age-related effects of density on children\u27s performance, reflecting a developmental restructuring of the mental lexicon from holistic into segmental representations that may play a role in phonological awareness. To further investigate density effects and their implications for development of phonological awareness, we compared performance on dense and sparse onset words. We adapted these materials to three phonological awareness tests that were pretested on adults then administered to preschool children who were expected to vary in phonological awareness skills. For both the adults and the children who passed a phonological awareness screening task, dense onset neighborhoods were associated with slower reaction times and increased errors. A separate comparison of word repetition by the children who passed and who did not pass the phoneme awareness screening failed to provide evidence that lexical restructuring was a sufficient condition for the attainment of phonological awareness. Both groups of children more accurately repeated words from high onset density neighborhoods, regardless of the level of their phonological awareness. Thus, we find no evidence of either age or ability driven effects in children\u27s performance, contradictory to a view that the attainment of phoneme awareness relates to developmental changes in the segmental representation of words in dense neighborhoods

The effects of education on homophobic attitudes in college students

The purpose of this study was to investigate whether attitudes towards homosexuals could be modified by education from a biological or moral/religious perspective. Sixty-eight male and fifty-seven female volunteers from a mid-sized Catholic liberal arts university were randomly assigned to two groups. The first group viewed a video discussing homosexuality from a biological perspective. The second group viewed a video discussing homosexuality from a moral/religious perspective. The subject\u27s attitudes towards homosexuality were measured with a modified version of Smith\u27s Homophobic Scale (Lumby, 1976) immediately after viewing the video. A two-way (video x gender) ANOVA revealed significant main effects of video for three items on the questionnaire. Subjects viewing the biological video were less likely to be homophobic than subjects viewing the moral religious video on one of the questions. Significant main effects for gender revealed that males were more likely than females to be homophobic on most of the items

Speech production deficits in early readers: predictors of risk

Speech problems and reading disorders are linked, suggesting that speech problems may potentially be an early marker of later difficulty in associating graphemes with phonemes. Current norms suggest that complete mastery of the production of the consonant phonemes in English occurs in most children at around 6–7 years. Many children enter formal schooling (kindergarten) around 5 years of age with near-adult levels of speech production. Given that previous research has shown that speech production abilities and phonological awareness skills are linked in preschool children, we set out to examine whether this pattern also holds for children just beginning to learn to read, as suggested by the critical age hypothesis. In the present study, using a diverse sample, we explored whether expressive phonological skills in 92 5-year-old children at the beginning and end of kindergarten were associated with early reading skills. Speech errors were coded according to whether they were developmentally appropriate, position within the syllable, manner of production of the target sounds, and whether the error involved a substitution, omission, or addition of a speech sound. At the beginning of the school year, children with significant early reading deficits on a predictively normed test (DIBELS) made more speech errors than children who were at grade level. Most of these errors were typical of kindergarten children (e.g., substitutions involving fricatives), but reading-delayed children made more of these errors than children who entered kindergarten with grade level skills. The reading-delayed children also made more atypical errors, consistent with our previous findings about preschoolers. Children who made no speech errors at the beginning of kindergarten had superior early reading abilities, and improvements in speech errors over the course of the year were significantly correlated with year-end reading skills. The role of expressive vocabulary and working memory were also explored, and appear to account for some of these findings

Identification of genetic variants associated with Huntington's disease progression: a genome-wide association study

Background Huntington's disease is caused by a CAG repeat expansion in the huntingtin gene, HTT. Age at onset has been used as a quantitative phenotype in genetic analysis looking for Huntington's disease modifiers, but is hard to define and not always available. Therefore, we aimed to generate a novel measure of disease progression and to identify genetic markers associated with this progression measure. Methods We generated a progression score on the basis of principal component analysis of prospectively acquired longitudinal changes in motor, cognitive, and imaging measures in the 218 indivduals in the TRACK-HD cohort of Huntington's disease gene mutation carriers (data collected 2008–11). We generated a parallel progression score using data from 1773 previously genotyped participants from the European Huntington's Disease Network REGISTRY study of Huntington's disease mutation carriers (data collected 2003–13). We did a genome-wide association analyses in terms of progression for 216 TRACK-HD participants and 1773 REGISTRY participants, then a meta-analysis of these results was undertaken. Findings Longitudinal motor, cognitive, and imaging scores were correlated with each other in TRACK-HD participants, justifying use of a single, cross-domain measure of disease progression in both studies. The TRACK-HD and REGISTRY progression measures were correlated with each other (r=0·674), and with age at onset (TRACK-HD, r=0·315; REGISTRY, r=0·234). The meta-analysis of progression in TRACK-HD and REGISTRY gave a genome-wide significant signal (p=1·12 × 10−10) on chromosome 5 spanning three genes: MSH3, DHFR, and MTRNR2L2. The genes in this locus were associated with progression in TRACK-HD (MSH3 p=2·94 × 10−8 DHFR p=8·37 × 10−7 MTRNR2L2 p=2·15 × 10−9) and to a lesser extent in REGISTRY (MSH3 p=9·36 × 10−4 DHFR p=8·45 × 10−4 MTRNR2L2 p=1·20 × 10−3). The lead single nucleotide polymorphism (SNP) in TRACK-HD (rs557874766) was genome-wide significant in the meta-analysis (p=1·58 × 10−8), and encodes an aminoacid change (Pro67Ala) in MSH3. In TRACK-HD, each copy of the minor allele at this SNP was associated with a 0·4 units per year (95% CI 0·16–0·66) reduction in the rate of change of the Unified Huntington's Disease Rating Scale (UHDRS) Total Motor Score, and a reduction of 0·12 units per year (95% CI 0·06–0·18) in the rate of change of UHDRS Total Functional Capacity score. These associations remained significant after adjusting for age of onset. Interpretation The multidomain progression measure in TRACK-HD was associated with a functional variant that was genome-wide significant in our meta-analysis. The association in only 216 participants implies that the progression measure is a sensitive reflection of disease burden, that the effect size at this locus is large, or both. Knockout of Msh3 reduces somatic expansion in Huntington's disease mouse models, suggesting this mechanism as an area for future therapeutic investigation

Does Strength of Phonological Representations Predict Phonological Awareness in Preschool Children?

Previous research has shown a clear relationship between phonological awareness and early reading ability. This article concerns some aspects of spoken language skill that may contribute to the development of phonological awareness, as manifested in rhyme awareness and phoneme awareness. It addresses the hypothesis that phonological awareness abilities are associated with measures that purportedly tap into the strength of phonological representations. We examined rhyme awareness, phoneme awareness, articulatory skill, speech perception, vocabulary, and letter and word knowledge in 40 children, aged 4 to 6, who were just beginning to be exposed to for-mat reading experiences in private preschools. The children also received cognitive tests and tests of reading ability. The results did not validate strength of phonological representation as a unitary construct underlying phonological awareness more generally, but instead revealed a selective pattern of associations between spoken language tasks and aspects of phonological awareness. Speech perception was closely associated with rhyme awareness measures when age, vocabulary, and letter knowledge were controlled. Children with a less developed sense of rhyme had a less mature pattern of articulation, independent of age, vocabulary, and letter knowledge. Phoneme awareness was associated with phonological perception and production. Children with low phoneme awareness skills showed a different pattern of speech perception and articulation errors than children with strong abilities. However, these differences appeared to be largely a function of age, letter knowledge, and especially vocabulary knowledge

Psychological/behavioral interventions for emerging adults with chronic pain

BackgroundEmerging adults, of whom significant numbers report chronic pain, are characterized as having unique needs and challenges. Psychological/behavioral treatments found to be beneficial for reducing pain outcomes in children and adults are understudied in emerging adults. Following a systematic review of the literature, our objective is to report on quantitative studies of psychological/behavioral interventions for chronic pain in emerging adults.MethodWe conducted a search of six databases (Cochrane Central Register of Controlled Trials, Google Scholar, ProQuest, PsycINFO, PubMed, and Web of Science) and reference sections in dissertations and systematic reviews to 4/29/2023. Keywords and phrases were search term combinations of “chronic/persistent pain”, “emerging/young adults,” and “intervention/treatment” using Boolean logic.ResultsOur review resulted in identifying 37 articles, of which 2 duplicates were removed, and 31 were further excluded by a screening process based on various inclusionary and exclusionary criteria. The search yielded four studies on psychological/behavioral interventions (yoga, acceptance and commitment therapy and relaxation), all of which positively affected the pain experience and/or pain-related outcomes. These studies presented issues in design such as not being blinded or randomized, having a small sample size, and potential confounds that were not reported or examined.DiscussionThe low number of studies reveals a large gap in the literature and is a call-to-action to further expand our understanding of effective and safer psychological/behavioral therapies for chronic pain in emerging adults. Successful pain management during this developmental phase may help young adults achieve positive trajectories for personal, occupational, relational, and health aspects of their lives
