Kinaesthesis: Its measurement, training and relationship to motor control

This paper reviews studies which demonstrate the importance of kinaesthesis in the acquisition and performance of motor skills. A method of measuring kinaesthetic sensitivity in children and adults (recently developed) is briefly described. Developmental trends in kinaesthetic perception are discussed and large individual differences found within age groups. It was shown that kinaesthetically undeveloped children can be trained to perceive and memorize kinaesthetic information with greatly improved accuracy. Furthermore perceptual training facilitates the performance of a drawing skill. On the basis of these results an argument is made for the importance of kinaesthesis in skilled motor behaviour.     

A longitudinal study of motor ability and kinaesthetic acuity in young children at risk of developmental coordination disorder

Several studies have linked poor kinaesthetic ability with poor motor coordination in school-aged children. However, few studies have investigated kinaesthesis in younger children. The aim of this study was to determine if preschool aged children who have been identified as at risk of developing developmental coordination disorder (DCD) have poorer kinaesthetic ability than matched controls. Kinaesthetic ability and performance IQ were examined in a group of children aged between 4 and 5 years. Following individual assessment of 291 children, 31 were identified as at risk of DCD at this age. One year later, 30 of these children were retested, and 23 were still found to be at risk. These children were matched on verbal IQ, age and sex with control children and their performance compared on the kinaesthetic acuity test (KAT) [D.J. Livesey and N.A. Parkes, Aust. J. Psychol., 47 (1995) 160] and three subtests of the WPPSI-R performance IQ (D. Wechsler, Manual for the Wechsler preschool and primary scale of intelligence--revised, Psychological Corporation, New York, 1989). Both the KAT and the performance subtest scores were found to be significantly poorer in the children at risk of DCD. Follow-up testing one year later showed that both groups improved their kinaesthetic acuity score although the control children remained significantly better than the children with poor motor coordination.     

Attention deficit disorder and age of onset of problem behaviors

In the course of a prospective longitudinal study, we examined age of onset of behavior problems in a group of boys and girls identified with attention deficit disorder (ADD) at age 11. Onset occurred during the preschool years, by the first year of schooling, or by the end of the second year of school. Onset was strongly related to informant source at age 11, pattern of comorbidity of disorder at age 11, and developmental language, perceptual motor, and IQ measures. Onset by the first year of schooling was particularly related to poor reading skills. By age 15, nearly three-quarters of those with onset of problems before age 6 had one or more DSM-III disorders.

Children’s Life Satisfaction: Developmental Trajectories and Environmental and Personality Predictors

Life satisfaction is a key indicator of children’s healthy development. Although the developmental changes of life satisfaction during adolescence have been investigated, the developmental trajectories of life satisfaction and related predictors during childhood remain unclear. Thus, the current study aimed to identify the developmental trajectories of life satisfaction covering the period from middle to late childhood as well as to examine the predictive roles of environmental factors (i.e., family dysfunction and basic psychological needs satisfaction at school), personality factors (i.e., neuroticism and extraversion), and their interactions in these developmental trajectories. An accelerated longitudinal design was used with Chinese elementary school students (N?=?1069, 45.8% girls, M _age?=?9.43, SD?=?0.95) of 3 cohorts (grade 3, grade 4, and grade 5) on 4 occasions at 6-month intervals. Growth mixture modeling analyses revealed three distinct trajectories of life satisfaction: “High-Stable” (88.8%), “High-Decreasing” (6.8%), and “Low-Increasing” (4.4%). Multivariate logistic regression analyses revealed that family dysfunction and neuroticism served as risk factors for adverse developmental trajectories of life satisfaction; whereas basic psychological needs satisfaction at school served as a protective factor. Furthermore, the interaction between family dysfunction and extraversion suggested that higher levels of extraversion buffered children against the negative effect of family dysfunction on the development of life satisfaction. The identification of three heterogeneous trajectory groups of children’s life satisfaction and key personality and environmental predictors associated with the trajectories suggests that specific interventions need to be tailored to the unique characteristics of the relevant trajectory groups.

     

Infant motor skill predicts later expressive language and autism spectrum disorder diagnosis

Motor difficulties may be an early Autism Spectrum Disorder (ASD) risk indicator and may predict subsequent expressive language skills. Further understanding of motor functioning in the first year of life in children with ASD is needed. We examined motor skills in 6-month-olds (n = 140) at high and low familial risk for ASD using the Peabody Developmental Motor Scales (Grasping, Visual-Motor Integration, and Stationary subscales). In Study 1, motor skill at 6 months predicted ASD status at 24–36 months; ASD was associated with poorer infant motor skills. In Study 2, motor skill at 6 months predicted expressive language at 30 and 36 months. Findings provide evidence that vulnerability in motor function early in development is present in ASD. Findings highlight the importance of developmental monitoring in high-risk infants and possible cascading effects of early disruption in motor development.     

Predicting school adjustment from motor abilities in kindergarten

The present study assessed the relations between basic motor abilities in kindergarten and scholastic, social, and emotional adaptation in the transition to formal schooling. Seventy‐one five‐year‐old kindergarten children were administered a battery of standard assessments of basic motor functions. A year later, children's adjustment to school was assessed via a series of questionnaires completed by the children and their class teachers. The results indicate that in addition to the already documented association between visual–motor integration and academic achievement, other motor functions show significant predictive value to both scholastic adaptation and social and emotional adjustment to school. The results further suggest a better prediction of scholastic adaptation and level of disruptive behaviour in school when using an aggregate measure of children's ability in various motor domains than when using assessments of singular motor functions. It is concluded that good motor ability may serve as a buffer to the normative challenges presented to children in the transition to school. In contrast, poor motor ability emerges as a vulnerability factor in the transition to formal schooling. Copyright © 2007 John Wiley & Sons, Ltd.     

Development of Cognitive Skills in Children with Motor Coordination Impairments at 12-Month Follow-up

The current study presents a 1-year follow-up investigation of the development of executive functions (i.e., inhibition, updating, and shifting) in children with motor coordination impairments. Cognitive and motor coordination skills of children (N = 94) aged between 5 and 7 years with and without motor coordination impairments were compared. A second focus of the study was on pre-academic skills. The results indicate marked stability of motor coordination impairments and persistent executive functioning deficits in motor-impaired children. Inhibition and shifting performance was consistently lower, compared to the children without motor coordination impairments. Moreover, children with motor coordination impairments showed lower pre-academic skills, facing a substantial disadvantage at the beginning of formal schooling. The combined cognitive and motor problems may be the result of an underlying inhibition deficit or a general automation deficit. Implications for intervention are discussed.     

IES Arrow-Dot longitudinal comparisons of personality development in preschool children.

19 preschool children were administered the IES Arrow-Dot test at the beginning and end of the school year and results compared with those based on a similar sample gathered the previous year. Trends for declining Impulsivity and Superego development were corroborated. Baselines for Impulsivity and Superego showed variation. Baselines and trends of rising Ego scores were supported. Results suggested suport for developmental trends of personality integration in preschool children.     

Spilling thoughts: configuring attentional resources in infants’ goal-directed actions

The focus and organization of attention in perception-action coupling is systematically examined in two studies involving 9 and 10 -month-old infants engaged in learning goal-directed behaviors. Experiment 1 (discrimination study) observed the influence of an attentionally demanding motor task on learning and cognition, while Experiment 2 (means-ends study) observed the influence of an attentionally demanding goal on motor planning and reaching performance. Taken together the results of these two experiments revealed that when mental processing resources were directed to thinking about movement, discrimination performance became compromised; conversely, when processing resources were directed to thinking about the goal-state, the motor planning and execution became compromised. These results suggest a “spilling forward” of thoughts onto actions and goal-states and thus an attention-driven cognition/action trade-off for infants’ goal-directed actions. Findings highlight the ultimate importance of emerging motor skills on cognition and are contextualized within the on-going dialogues and developmental debates surrounding perceptual-motor skill development and problem-solving strategies during the first year.     

Trimestre de naissance et parcours scolaire

This article examines the effect of quarter of birth on school years during kindergarten and primary school from data of several recent researches realized in France. Results show that pupils born at the beginning of the civil year obtain best academic performances that these born at the end of the year and have a more high probability to follow schooling without repeating. Nevertheless, the effect of quarter of birth seems more marked in kindergarten and first elementary school year than to more advanced steps of schooling (3rd primary year and 1st year of secondary school). Pedagogical implications of gaps in psychological development linked to the quarter of birth and to the age of children are discussed.     

Reading Development in Typically Developing Children and Children With Prenatal or Perinatal Brain Lesions: Differential School Year and Summer Growth

Summer slide, uneven growth of academic skills during the calendar year, captures the fact that the learning gains children make during the school year do not continue at the same pace over the summer, when children are typically not in school. We compared growth of reading skills during the school year and during the summer months in children with prenatal or perinatal brain lesions (PL) and typically developing (TD) children from varying socioeconomic-status (SES) backgrounds as a new way to probe the role of structured environmental support in functional plasticity for reading skills in children with PL. Results showed that children with PL performed worse than TD children on both reading decoding and reading comprehension. Group differences were primarily driven by children with larger lesions and children with right-hemisphere lesions (RH). For reading comprehension, children with RH showed greater growth during the school year but more slide during the summer months than both TD children and children with left-hemisphere lesions, implicating a particularly strong role of structured input in supporting reading comprehension in this group. TD children from lower-SES backgrounds fell behind their TD peers from higher-SES backgrounds on decoding and reading comprehension but did not show differential patterns of school year and summer growth. Overall, results highlight the importance of considering the role of a host of factors interacting at multiple levels of analyses, including biological and environmental, in influencing developmental trajectories of TD children and atypically developing children.     

Correlated longitudinal changes across linguistic, achievement, and psychomotor domains in early childhood: evidence for a global dimension of development

An important question within developmental psychology concerns the extent to which the maturational gains that children make across multiple diverse domains of functioning can be attributed to global (domain-general) developmental processes. The present study investigated this question by examining the extent to which individual differences in change across children's development in five different domains are correlated. Multivariate growth-curve models were fit to longitudinal data on linguistic, mathematics, reading, gross motor, and fine motor skills in 8950 children ranging in age from 44 to 86 months (3.7 years to 7.2 years). All five rates of change were positively intercorrelated. A common factor accounted for 42% of the individual differences in change. These results suggest that a global dimension underlies substantial proportions of cognitive and psychomotor development.     

Motor and cognitive proficiency of learning disabled and normal children

Motor and cognitive skills of learning disabled (N = 32) and normal (N = 32) boys were compared on the Modified Lincoln-Oseretsky Motor Development Scale and on the WISC-R Vocabulary and Block Design subtests. Eight learning disabled and eight normal boys were tested at four age levels from 8 to 11 years. All boys were of normal intelligence. Motor and cognitive skills of the learning disabled boys were significantly below those of the normal boys and below those of the normative group. Chronological age was not a significant factor in relationship to either motor or cognitive skills. Intercorrelations indicated that in the learning disabled group Block Design, but not Vocabulary, was significantly related to motor scores at the 8- and 9-year ages. These results suggest that a common factor relating to perceptual-motor coordination and efficiency may be involved on the Lincoln-Oseretsky and Block Design subtest for young learning disabled children but not for older learning disabled children or for normal children.     

The differential effects of age and first grade schooling on the development of infralogical and logico-mathematical concrete operations

Using the “between-grade levels” regression discontinuity design, this study examined the hypothesized differential sensitivity of logico-mathematical (LM) and infralogical (IL) operational tasks to the effects of chronological age and first grade schooling in a sample of 580 1st and 2nd grade Israeli children. The results indicate that the development of logico-mathematical operational skills (classification, class inclusion and transitivity) is mainly attributable to schooling. In contrast, the effect of schooling on the development of conservation of mass, liquid quantity and number (clearly an infralogical task) is negligible; acquisition of conservation is almost exclusively due to maturation and out-of-school experiences. The results support the theoretical predictions derived from French-Swiss research of the last two decades and are inconsistent with claims regarding the specificity of schooling effects to tasks that are taught in school.     

Japanese children's numerical competencies: age- and schooling-related influences on the development of number concepts and addition skills

Using a cutoff design (J. Bisanz, F. J. Morrison, & M. Dunn, 1995) to separate school-related influences from those that are age related, the study investigated the development of number concepts and addition skills in Japanese children. Three groups of kindergarten and 1st grade children who differed in age and/or school experiences completed tasks on their numerical competencies 1 and 6 months after school entrance. Children's use of addition strategies, rather than their solution accuracy, changed primarily as a function of schooling, not age. Children's Base 10 number concepts improved with the amount of schooling, as well as with other social and age-related factors. Results suggest that schooling is an important determinant in developing Japanese-speaking children's numerical competencies, which were not explained solely by their language characteristics or by age-related factors.     

Stability of developmental status and risk of impairment at 24 and 36 months in late preterm infants

BackgroundFew studies investigated whether late preterm infants might have developmental delays in several domains in early life and how stable the lag in developmental status might be.AimWe aimed to examine the stability of potential delays across developmental domains at 24 and 36 months of age in late preterm (34°-36⁶ weeks) and term (≥37 weeks) children and whether the risk of delays remained high at 36 months.Study design, subjects, and outcome measureWe conducted a prospective cohort analysis of the children of pregnant women participating in the Vitamin Antenatal Asthma Reduction Trial (VDAART). 652 children who were prospectively followed up and had parent-completed Ages Stages Questionnaires (ASQ-3) questionnaires at both 24 and 36 months were analyzed to assess their domain-specific developmental status.Results6.61 % (42/635) of children had a late preterm birth. Developmental delays were stable between 24 and 36 months on all 5 domains for the children born preterm and on 4/5 domains for those born at term. The developmental domains with the status stability at 24 and 36 months in both late preterm and term children were the gross motor, communication, personal-social skills, and problem-solving. Late preterm children compared with term children remained at higher risk of delays at 36 months for gross motor, communication, and problem-solving skills (aOR = 4.54, 95 %CI: 1.81−10.79; aOR = 8.60, 95 %CI: 3.10−23.28 and aOR = 3.80, 95 %CI: 1.58−8.73, respectively).ConclusionLate preterm birth is associated with suboptimal development and stability in several domains at both 24 and 36 months and compared with term birth, requiring early monitoring and assessment of the developmental lag to avoid potential long-term implications.

The effect of month of birth on the attainments of primary and secondary school pupils

Background Previous research has produced conflicting results regarding the effects of season of birth and age‐position on cognitive attainments. In Northern Ireland the school year divides the summer season into two providing an opportunity to evaluate the relative contribution of season of birth and age‐position effects. Aims To investigate the relationship between attainment in literacy skills and month of birth for primary and secondary school pupils and to determine the relationship between motor skills and month of birth in primary school pupils. Sample One thousand one hundred and twenty four primary school pupils participated, and results for key stage 3 (KS3) English and GCSE English Language, for 3,493 Year 10 and 3,697 Year 12 secondary school pupils, respectively, were obtained. Method Primary school pupils were individually assessed using standardised reading and spelling tests, as well as tests of motor skill. They were also assessed using a standardised group reading test in their class groups. For the secondary school pupils, the results for two year cohorts, in KS3 English and GCSE English language, respectively, were analysed. Results For the primary school pupils there was evidence of both a season of birth and an age‐position effect on all of the cognitive measures, particularly in the early years of schooling. There was, also, evidence of a significant age‐position effect at both KS3 and GCSE in favour of the older pupils. For the younger primary school pupils there was evidence of significant age‐position effects on both motor measures. Conclusions The findings from the present study suggest that month of birth may be related to both season of birth and age‐position effects. These effects may be compounded, particularly in the early years of primary school, when summer born children are youngest in their year, as in England. In Northern Ireland, age‐position effects are also evident in secondary school public examination results, which may have implications for long‐term life choices.
