This follow-up study investigated the associations of childhood learning disabilities (LDs) with adult-age anxiety, depression, and unemployment. Psychosocial problems in childhood and psychiatric diagnoses and lack of education in adolescence were studied as potential mediators, and gender and mother's education were studied as potential moderators of these associations. Data on childhood clinical neuropsychological assessments and lifelong register data on individuals with childhood LD (n = 430; 301 [70%] males; 20–39 years of age) and matched controls (n = 2,149) were applied. Mediation analyses were performed using structural equation modeling. Childhood LDs exerted a significant, but relatively small effect on psychiatric diagnoses in adolescence, which predicted adult-age depression and anxiety. Learning disabilities were related to unemployment both directly and via psychiatric diagnoses in adolescence. Examination of differences in the effects on adult-age outcomes of subtypes of LDs revealed mathematical disability to be more strongly associated with psychosocial problems in childhood and psychiatric problems in adolescence and adulthood than reading disability. Our findings show that LD has small and mostly indirect effects on the risk for later well-being problems. The findings emphasize the importance of adolescence in predicting adult-age psychiatric and employment problems and call for more holistic support for individuals with LDs. [ABSTRACT FROM AUTHOR]

We examined frequency of adult-age reading disability (RD) and its childhood predictors among 48 adults (20 to 39 years) with documented childhood RD, and contrasted their cognitive skills, education, and employment with 37 matched controls. Among individuals with childhood RD, more than half had improved in their reading fluency to the level where the set criterion for adult-age RD was not met anymore. More fluent rapid naming, less severe childhood RD, and multiple support providers in childhood together predicted improvement of reading fluency. More fluent naming differentiated the childhood RD participants whose reading fluency had improved by adult-age from those participants whose RD persisted to adult-age. All the individuals with childhood RD performed weaker than the controls in adult-age working memory, processing speed, and verbal skills. Educational level among both RD groups was lower than that among the controls. Unemployment of individuals with persistent adult-age RD (31.6%) was higher than that of individuals with improved adult-age RD (13.8%) or that of the controls (8.1%). According to our findings, rapid naming is one evident factor differentiating individuals with persisted RD from those with ameliorated reading fluency. Also, better adult-age reading fluency has significance for adult-age employment among individuals with childhood RD. [ABSTRACT FROM AUTHOR]

Purpose: This longitudinal study examined the development of prelinguistic skills and the continuity of communication and language from the prelinguistic stage to school age. Method: Prelinguistic communication of 427 Finnish children was followed repeatedly from 6 to 18 months of age (n = 203-322 at ages 6, 9, 12, 15, and 18 months), and its associations with language ability at ages 2;0 (n = 104), 3;0 (n = 112), 4;7 (n = 253), 5;3 (n = 102), and 7;9 (n = 236) were examined using latent growth curve modeling. Results: Prelinguistic development across several skills emerged as a rather stable intraindividual characteristic during the first 2 years of life. Continuity from prelinguistic development to later language ability was indicated. The common level and growth of prelinguistic skills were significant predictors of language ability between ages 2;0 (years;months) and 7;9; the percentage explained varied between 10.5% and 53.3%. A slow pace of development across multiple skills, in particular, led to weaker language skills. Conclusions: The results support (a) the idea of a developmental continuum from prelinguistic to linguistic ability and (b) the dimensional view of language ability by indicating that individual variations in early communication skills show consistency that extends beyond the toddler years. Our results also advocate developmental surveillance of early communication by emphasizing the significance of growth in predicting language development. [ABSTRACT FROM AUTHOR]

Purpose: This study focused on developmental trajectories of prelinguistic communication skills and their connections to later parent-reported language difficulties. Method: The participants represent a subset of a community-based sample of 508 children. Data include parent reports of prelinguistic communication skills at 12, 15, 18, and 21 months and language difficulties at age 4;7 (years;months). The authors used latent profile analysis to identify groups of children with differing developmental trajectories of prelinguistic communication skills (n = 271). The relations among these groups and follow-up data of parent-reported concerns of language development (n = 187), as well as the role of gender, were examined. Results: Six meaningful prelinguistic communication groups were identified with the latent profile analysis, and these groups showed connections to later parent-reported concerns of language difficulties. Delayed early expressive language and a minor delay of overall performance, together with symbolic difficulties, appeared as predictors of later language difficulties. Nearly 80% of the children whose parents reported language-related concerns at the follow-up stage could already be identified before their 2nd birthday. Conclusion: The results support the potential of early screening in identifying children at risk of developing language difficulties, particularly when screening includes repeated surveillance of more than one area of communication skills.

Test-taking behaviors (i.e., task focus, maintenance of attention, and cooperation) affect children's cognitive test performance, and, thus, it is critical to take test-taking behavior into account when drawing conclusions and making recommendations. Prior studies have evaluated test-taking behaviors at the end of the assessment; the present study focused on the fluctuation of cooperation and attention during a neuropsychological assessment. We examined the attention and cooperation of 5-year-old children in a test-taking situation; the associations between these aspects of their test-taking behavior and the children's concurrent neurocognitive test performance, IQ, and parent-rated behavior; and the associations with their IQ, behavioral outcomes, and academic achievement at 8 years of age. The data (for 76 boys and 63 girls) were drawn from the Jyvaskyla Longitudinal Study of Dyslexia (Lyytinen et at., 2001, 2004). All the children were Caucasian and spoke Finnish as their native language. As a whole, the 5-year-old children showed high cooperation and attention, but a slight decrement in test-taking behavior toward the end of the session was rather common. Three subgroups of children with different levels of cooperation and attention were identified. Children in the subgroup with nonoptimal attention and cooperation showed decreasing neurocognitive test performance toward the end of the assessment session. They also showed more inattentive behavior 3 years later. The findings imply that the examiner's observations of waning attention and cooperation during the assessment session are highly relevant, as these provide stable and clinically meaningful information about the child's behavioral tendencies.

This longitudinal study examined the predictive associations between cumulative multidomain risk factors and cognitive (IQ), academic (reading fluency), and social adaptive outcomes at 8 to 9 years among 190 children with or without familial risk for dyslexia. Other risk factors included parental and neurocognitive risks assessed when the children were 1 to 6 years of age. Risks accumulated more among children with familial risk for dyslexia than among children without familial risk. A higher number of risks was associated with poorer performance in all outcome measures as postulated by the cumulative risk model. However, when the effects of individual risk variables were controlled for at the outset, the cumulative risk indices did not have incremental effects beyond those of individual risks. This suggests that the detrimental effect of several risks was due to the content-specific effect of individual risks. Children with familial risk were not differentially affected by the number of risks. [ABSTRACT FROM AUTHOR]

Understanding of the factors that underlie the development of fluency in reading and arithmetic is limited. This longitudinal study examined whether verbal counting and rapid automatized naming (RAN) were predictors of arithmetic and reading fluency in a population-based sample and to what extent related early emerging cognitive abilities and socioeconomic background accounted for the predictive power of counting and RAN. In addition, in order to examine the uniqueness of counting as a numerical predictor of reading fluency, the influence of another early number skill—number concept—was controlled. Three hundred and seventy-eight Finnish children were followed from kindergarten to Grade 3 (from 6 to 10 years). The results demonstrated that counting and RAN were powerful predictors of arithmetic and reading fluency. Controlling for phonological awareness, vocabulary, memory, and mother's education had little impact on the predictive relation of counting and RAN to fluency in arithmetic and reading. The number concept skill did not remove the predictive relation of counting with reading or arithmetic and had only a predictive relation to arithmetic fluency after controlling for cognitive skills. Findings suggest that the strong predictive relation counting had with reading and arithmetic fluency does not exist with all number skills. This finding supports the view that there is something specific in the verbal counting skill related to the development of fluency, which should be studied in the future. [ABSTRACT FROM AUTHOR]

This study examined whether counting and rapid automatized naming (RAN) could operate as significant predictors of both later arithmetic calculation and reading fluency. The authors also took an important step to clarify the cognitive mechanisms underlying these predictive relationships by controlling for the effect of phonological awareness and verbal short-term memory. Due to rather strong covariance between verbal short-term memory and phonological awareness, short-term memory could be controlled only partially. Participants, 200 children from a longitudinal study, were followed from age 5 to 10 years. Structural equation modeling showed counting to be a strong predictor, not only of later calculation but also of reading fluency. Similarly, RAN predicted later calculation as well as reading fluency. These results indicated that counting and RAN were not skill-specific predictors. Phonological awareness explained part of counting and RAN. However, the predictive effects of these 2 skills on calculation and reading remained even after phonological awareness and partially for verbal short-term memory were controlled. Thus, further exploration of other cognitive processes underlying these 2 abilities is needed. [ABSTRACT FROM AUTHOR]
