Longitudinal relationships between speech perception,phonological skills and reading in children at high‐risk of dyslexia

Speech perception deficits are commonly reported in dyslexia but longitudinal evidence that poor speech perception compromises learning to read is scant. We assessed the hypothesis that phonological skills, specifically phoneme awareness and RAN, mediate the relationship between speech perception and reading. We assessed longitudinal predictive relationships between categorical speech perception, phoneme awareness, RAN, language, attention and reading at ages 5½ and 6½ years in 237 children many of whom were at high risk of reading difficulties. Speech perception at 5½ years correlated with language, attention, phoneme awareness and RAN concurrently and was a predictor of reading at 6½ years. There was no significant indirect effect of speech perception on reading via phoneme awareness, suggesting that its effects are separable from those of phoneme awareness. Children classified with dyslexia at 8 years had poorer speech perception than age‐controls at 5½ years and children with language disorders (with or without dyslexia) had more severe difficulties with both speech perception and attention control. Categorical speech perception tasks tap factors extraneous to perception, including decision‐making skills. Further longitudinal studies are needed to unravel the complex relationships between categorical speech perception tasks and measures of reading and language and attention.     

Dynamic relationships between phonological memory and reading: A five year longitudinal study from age 4 to 9

We reconcile competing theories of the role of phonological memory in reading development, by uncovering their dynamic relationship during the first 5 years of school. Phonological memory, reading and phoneme awareness were assessed in 780 phonics‐educated children at age 4, 5, 6 and 9. Confirmatory factor analyses demonstrated that phonological memory loaded onto two factors: verbal short‐term memory (verbal STM; phonological tasks that loaded primarily on serial order memory) and nonword repetition. Using longitudinal structural equation models, we found that verbal STM directly predicted early word‐level reading from age 4 to 6, reflecting the importance of serial‐order memory for letter‐by‐letter decoding. In contrast, reading had no reciprocal influence on the development of verbal STM. The relationship between nonword repetition and reading was bidirectional across the 5 years of study: nonword repetition and reading predicted each other both directly and indirectly (via phoneme awareness). Indirect effects from nonword repetition (and verbal STM) to reading support the view that phonological memory stimulates phonemically detailed representations through repeated encoding of complex verbal stimuli. Similarly, the indirect influence of reading on nonword repetition suggests that improved reading ability promotes the phoneme‐level specificity of phonological representations. Finally, the direct influence from reading to nonword repetition suggests that better readers use orthographic cues to help them remember and repeat new words accurately.

The genesis of reading ability: What helps children learn letter-sound correspondences?

Knowledge of letter-sound correspondences underpins successful reading acquisition, and yet little is known about how young children acquire this knowledge and what prior information they bring to the learning process. In this study, we used an experimental training design to examine whether either prior letter awareness or prior phonemic awareness directly assists preliterate children in subsequently learning letter-sound correspondences. Here 76 preschoolers received 6 weeks of training in either letter awareness, phonemic awareness, or control tasks and then received a further 6 weeks of training in either letter-sound correspondences or control tasks. There was limited evidence that prior training in either phoneme or letter awareness directly assisted learning of letter-sound correspondences, although phonemically trained children appeared to show some advantage on recognition tasks. Overall, the data suggest that there is little value in training preschoolers in either letter forms or sounds in isolation in advance of providing instruction on the links between the two.     

Relation of perinatal risk and early parenting to executive control at the transition to school

Executive control (EC) develops rapidly during the preschool years and is central to academic achievement and functional outcome. Although children with perinatal adversity are at known risk for EC impairments, little is known about the underlying nature of these impairments or the mechanisms that contribute to their development over time. Drawing on a cohort of 110 high‐risk children born very preterm (VPT; < 33 weeks / < 1500 g) and 113 healthy full‐term children, this study examined the implications of perinatal adversity and early parenting for children's EC as they transitioned to formal schooling. Parent supportive presence, intrusiveness, and parent–child synchrony were observed during a series of problem‐solving tasks at ages 2 and 4 years. At age 6, children completed a comprehensive battery of EC tasks. Academic outcomes were assessed at age 9. The VPT group showed global EC impairments at age 6, although the unitary factor that best characterized the structure of EC was the same in both groups. High‐risk dyads were characterized by more intrusive and less synchronous parent–child interactions in early childhood, which in turn predicted poorer child EC at age 6. EC partially mediated the relation of risk status to poorer academic achievement at age 9. Findings demonstrate the cumulative effects of perinatal adversity on children's EC in the crucial transition to schooling. They also highlight the importance of the parent–child relationship as a target for intervention efforts to help mitigate these effects.     

Children's perception and understanding of (dis)similarities among dynamic bodily/facial expressions of happiness, pleasure, anger, and irritation

The current study examined the abilities of children (6 and 8 years of age) and adults to freely categorize and label dynamic bodily/facial expressions designed to portray happiness, pleasure, anger, irritation, and neutrality and controlled for their level of valence, arousal, intensity, and authenticity. Multidimensional scaling and cluster analyses showed that children (n = 52) and adults (n = 33) structured expressions in systematic and broadly similar ways. Between 6 and 8 years of age, there was a quantitative, but not a qualitative, improvement in labeling. When exposed to rich and dynamic emotional cues, children as young as 6 years can successfully perceive differences between close expressions (e.g., happiness, pleasure), and can categorize them with clear boundaries between them, with the exception of irritation, which had fuzzier borders. Children’s classifications were not reliant on lexical semantic abilities and were consistent with a model of emotion categories based on their degree of valence and arousal.     

Group Affiliations of University Students in the Arab Middle East

Summary

A study was undertaken in Morocco in order to separate the effects of age and formal schooling on the development of cognitive style. A total of 384 boys (age range: 6–22 years) were selected from environmental backgrounds including: urban/schooled, rural/schooled, urban/nonschooled, and rural/nonschooled. Results indicated that chronological age and schooling played major, but independent roles in promoting perceptual development (and “field independent” cognitive style), while childhood environment appeared to have little effect. It was concluded that general statements about the effects of cultural socialization practices on cognitive style should be tempered by considering particular environmental experiences (such as formal schooling) that may significantly influence cognitive assessment techniques that are said to measure cognitive style.     

Assessment of working memory components at 6years of age as predictors of reading achievements a year later

The ability of working memory skills (measured by tasks assessing all four working memory components), IQ, language, phonological awareness, literacy, rapid naming, and speed of processing at 6 years of age, before reading was taught, to predict reading abilities (decoding, reading comprehension, and reading time) a year later was examined in 97 children. Among all working memory components, phonological complex memory contributed most to predicting all three reading abilities. A capacity measure of phonological complex memory, based on passing a minimum threshold in those tasks, contributed to the explained variance of decoding and reading comprehension. Findings suggest that a minimal ability of phonological complex memory is necessary for children to attain a normal reading level. Adding assessment of phonological complex memory, before formal teaching of reading begins, to more common measures might better estimate children’s likelihood of future academic success.     

Do dyslexics have difficulty accessing articulatory information?

Summary Dyslexic and normal readers of the same reading age of around eight years, but of different chronological age (ten and eight years) were given an articulation accessing and a phoneme segmentation task. For the former task they had to indicate which of several schematic drawings corresponded to the position of their tongue, teeth, and lips for a given phoneme. The dyslexic children experienced great difficulty with this task while they were equal to the normal children on a simple phoneme segmentation task. These results were replicated with two further samples of dyslexic and normal children. It is hypothesized that awareness of articulation processes is an important factor in explanations of dyslexia.     

Testing the concurrent and predictive relations among articulation accuracy, speech perception, and phoneme awareness

The relations among articulation accuracy, speech perception, and phoneme awareness were examined in a sample of 97 typically developing children ages 48 to 66 months. Of these 97 children, 46 were assessed twice at ages 4 and 5 years. Children completed two tasks for each of the three skills, assessing these abilities for the target phoneme /r/ and the control phoneme /m/ in the word-initial position. Concurrent analyses revealed that phoneme-specific relations existed among articulation, awareness, and perception. Articulation accuracy of /r/ predicted speech perception and phoneme awareness for /r/ after controlling for age, vocabulary, letter-word knowledge, and speech perception or phoneme awareness for the control phoneme /m/. The longitudinal analyses confirmed the pattern of relations. The findings are consistent with a model whereby children's articulation accuracy affects preexisting differences in phonological representations and, consequently, affects how children perceive, discriminate, and manipulate speech sounds.     

SES differences in young children’s metacognition in the context of mathematical problem solving

This investigation examines socioeconomic (SES) differences in young children’s development of key aspects of metacognition and related language. The participants were 102 children ranging in age from 4 years 0 months to 5 years 11 months in five daycare centers located in New York City. Metacognitive abilities and language were observed as children engaged in an individually administered clinical interview concerning mathematical problem solving. The results indicate that the ability to describe thinking and explain ideas is stronger in the upper-SES group than the middle- or lower-SES groups. The findings also indicate that all the SES groups, and children of both ages, show little awareness of mistakes and adaptability without adult assistance. The capacity to express thinking was found to increase with age during early childhood. The results suggest that young children begin to employ rudimentary forms of metacognition before the onset of formal schooling. Implications for education are discussed.     

A Comparison of Phonological Awareness Skills in Early French Immersion and English Children

This 2-year study examined the effects of early second language exposure on phonological awareness skills. Syllable, onset-rime and phoneme awareness skills of 72 anglophone children attending English or French immersion programs in primary and grade 1 were investigated. Three-way mixed ANOVAS revealed the following effects and interactions. In terms of grade effect, grade 1 students performed significantly better than primary students on phoneme and onset-rime tasks. A stimulus language effect was observed for the three levels of phonological awareness. All children performed better on English tasks than on French ones. Interaction effects of stimulus language by program were revealed for phoneme as well as syllable tasks. Posthoc analyses revealed that French students performed better on English phoneme and syllable tasks than on French, while English students performed better than French immersion students on French syllable tasks. Correlational analyses revealed significant relationships between reading and phoneme and onset-rime phonological awareness tasks regardless of program of instruction (English, French immersion) or language of reading test (English, French). Syllable awareness was only significantly correlated with the French non-word reading task for the French immersion students.     

Effects of orthographic transparency on reading and phoneme awareness in children learning to read in Wales

The relationship between the development of reading skills and the consistency of the orthography (writing system) is investigated in a study that examines reading acquisition in children living in Wales. Performance of children learning to read Welsh (a transparent alphabetic orthography) on tests of reading and phoneme detection was compared with the performance of children learning to read English (an opaque alphabetic orthography). The children were tested during their second year of formal reading instruction at school when they were aged between 5 and 6 years, and again one year later. The children learning to read in Welsh performed significantly better at reading both real words and nonwords than children learning to read in English. The English readers made fewer phonologically based reading errors. The Welsh readers also performed better on a phoneme awareness task. These findings support the claim that children learn to read more quickly in a transparent orthography, and provide further evidence that the consistency of the orthography influences the initial adoption of different strategies for word recognition.     

Not all phonological awareness deficits are created equal: evidence from a comparison between children with Otitis Media and poor readers

Children with reading difficulties and children with a history of repeated ear infections (Otitis Media, OM) are both thought to have phonological impairments, but for quite different reasons. This paper examines the profile of phonological and morphological awareness in poor readers and children with OM. Thirty‐three poor readers were compared to individually matched chronological age and reading age controls. Their phonological awareness and morphological awareness skills were consistently at the level of reading age matched controls. Unexpectedly, a significant minority (25%) of the poor readers had some degree of undiagnosed mild or very mild hearing loss. Twenty‐nine children with a history of OM and their matched controls completed the same battery of tasks. They showed relatively small delays in their literacy and showed no impairment in morphological awareness but had phonological awareness scores below the level of reading age matched controls. Further analysis suggested that this weakness in phonological awareness was carried by a specific weakness in segmenting and blending phonemes, with relatively good performance on phoneme manipulation tasks. Results suggest that children with OM show a circumscribed deficit in phoneme segmentation and blending, while poor readers show a broader metalinguistic impairment which is more closely associated with reading difficulties.     

Genetic and environmental influences on individual differences in printed word recognition

The genetic and environmental etiologies of individual differences in printed word recognition and related skills were explored in 440 identical and fraternal twin pairs between 8 and 18 years of age. A theoretically driven measurement model identified five latent variables: IQ, phoneme awareness, word recognition, phonological decoding, and orthographic coding. Cholesky decomposition models on these five latent constructs revealed the existence of both common and independent genetic effects, as well as non-shared environmental influences. There was evidence for moderate genetic influences common between IQ, phoneme awareness, and word-reading skills, and for stronger IQ-independent genetic influences that were common between phoneme awareness and word-reading skills, particularly phonological decoding. Phonological and orthographic coding skills in word recognition had both significant common and significant independent genetic influences, with implications for "dual-route" and "connectionist" reading models, subtypes of reading disabilities, and the remediation of reading disabilities.     

Neighbourhood,school and family determinants of children's aspirations in primary school

Aspirations can be important for young children as well as adolescents. However, there is little research on the determinants of aspirations in young children. We carried out this study to investigate the early contextual (neighbourhood, school and family) determinants of occupational aspirations in primary school children. Our sample comprised children from the Millennium Cohort Study who lived in England in the beginning of our study period (n = 10,086; 5,126 boys). Occupational aspirations were measured at age 7 years, while their contextual determinants were measured in the previous data sweeps, at ages 3 and 5 years. We fitted structural equation models to test the role of family and neighbourhood socio-economic status (SES) and child ethnicity in predicting aspirations both directly and via their associations with parental involvement, household chaos, school-level achievement and child cognitive ability. We found that the only significant determinants of aspirations at age 7 years were family SES and ethnicity, and only in boys. Family SES and ethnicity were also related to parental involvement, household chaos, cognitive ability and school-level achievement, but none of these factors predicted aspirations. Supplementary analysis showed that family SES was a particularly powerful determinant of the aspirations of white compared to non-white boys.     

Influences of schooling and urban-rural residence on gender differences in cognitive abilities and academic achievement

A total of 1151 children from indigenous Quechua-speaking families residing in squatter settlements of the city and in two remote rural environments in Peru was given a battery of 16 tests of academic achievement and cognitive abilities. The former tests assessed reading and mathematics achievement and the latter tapped a broad range of cognitive functions. Children were enrolled in first, second, or third grade or did not attend school. “Younger” children were from 6 to 8 years old, and “older” children were from 9 to 12 years old. Large differences in cognitive functioning were associated with attendance at school, grade in school, age, and urban-rural residence. Gender was found to account for less than 5% of the variance in children's performance on cognitive and academic tasks. Gender effects appeared to decline with increased amount of schooling. This was reflected in interactions involving gender and schooling and in a greater number of significant gender effects for children who did not attend school or were in first grade. The results present a complicated picture of various interactional effects of task, location, age, and schooling on the detected gender differences in cognitive abilities and academic achievement.     

Does the Animal Fun program improve motor performance in children aged 4–6 years?

The Animal Fun program was designed to enhance the motor ability of young children by imitating the movements of animals in a fun, inclusive setting. The efficacy of this program was investigated through a randomized controlled trial using a multivariate nested cohort design. Pre-intervention scores were recorded for 511 children aged 4.83 years to 6.17 years (M = 5.42 years, SD = 3.58 months). Six control and six intervention schools were compared 6 months later following the intervention, and then again at 18 months after the initial testing when the children were in their first school year. Changes in motor performance were examined using the Bruininks-Oseretsky Test of Motor Proficiency short form. Data were analyzed using multi-level-mixed effects linear regression. A significant Condition × Time interaction was found, F(2, 1219) = 3.35, p = .035, demonstrating that only the intervention group showed an improvement in motor ability. A significant Sex × Time interaction was also found, F(2, 1219) = 3.84, p = .022, with boys improving over time, but not girls. These findings have important implications for the efficacy of early intervention of motor skills and understanding the differences in motor performance between boys and girls.     

Predictors of reading development in deaf children: A 3-year longitudinal study

The development of reading ability in a group of deaf children was followed over a 3-year period. A total of 29 deaf children (7-8 years of age at the first assessment) participated in the study, and every 12 months they were given a battery of literacy, cognitive, and language tasks. Earlier vocabulary and speechreading skills predicted longitudinal growth in reading achievement. The relations between reading and the predictor variables showed developmental change. Earlier reading ability was related to later phonological awareness skills, suggesting that deaf children might develop their phonological awareness through reading. Deaf children who had the most age-appropriate reading skills tended to have less severe hearing losses and earlier diagnoses and also preferred to communicate through speech. The theoretical implications of the role for speechreading, vocabulary and phonological awareness in deaf children’s literacy are discussed.     

A randomized controlled trial of the impact of a teacher classroom management program on the classroom behavior of children with and without behavior problems

This randomized controlled trial (RCT) evaluated the efficacy of the Incredible Years (IY) Teacher Classroom Management (TCM; Webster-Stratton & Reid, 2002) program to assess whether training teachers in IY-TCM principles improve teacher behavior, whether any observed improvements impact pupil behavior classroom-wide, and whether these effects can be demonstrated with children at risk of developing conduct problems. Six intervention and six control classrooms comprising 12 teachers and 107 children (aged 3 to 7 years) were recruited. Children were screened for high or low behavior problems using the cut-off points of the teacher-rated Strengths and Difficulties Questionnaire (Goodman, 1997). The primary outcome measure was independent classroom observations using the Teacher–Pupil Observation Tool (Martin et al., 2010). Multilevel modeling analyses were conducted to examine the effect of the intervention on teacher, classroom, and child behavior. Results showed a significant reduction in classroom off-task behavior (d = 0.53), teacher negatives to target children (d = 0.36), target child negatives towards the teacher (d = 0.42), and target child off-task behavior (d = 0.48). These preliminary results demonstrate the potential impact of IY-TCM on both teacher and child behavior.     

Rhyming abilities in a dual-task in school-age children who stutter

PurposeWe compared school-age children who stutter (CWS) and age and gender matched control participants (CWNS) in a dual-task involving a word-level rhyming task and a tone task involving pitch decisions.MethodsParticipants were 30 children (CWS, n = 15) between 7 and 16 years. Auditory word – picture stimuli pairs from the rhyme task were categorized into nonrhyme (e.g., bear-cart), rhyme (e.g., bear-pear), and replica (e.g., bear-bear) categories. The effort associated with managing resources in the dual-task was varied through the manipulation of stimulus onset asynchrony (SOA) between the stimuli of the two tasks. Mixed methods analyses of the response time (RT, ms) and error (%) data were conducted with Group, Category, and SOA as the fixed effects and participants as the random effect. Age and phoneme awareness skills were included in the analyses.ResultsMore rhyming errors and a significant positive correlation between rhyming errors and age was observed in the CWS compared to the CWNS. Compared to the CWNS, a higher percentage of rhyming errors was observed in the rhyme than the nonrhyme and replica categories in the CWS in both the SOA conditions, and this effect was influenced by age and phoneme awareness skills. Analysis of the tone task data indicated that a subgroup of CWNS with higher phoneme awareness skills showed reduced RT difference between the long and the short SOA conditions thereby suggesting higher efficiency with resource allocation for dual tasking. Task-specific differences between the CWS and CWNS are interpreted to suggest limitations in the encoding of the phonological aspects of covert speech in a dual-task.
