Dimensions of executive functioning: Evidence from children

2003

This study investigated dimensions of executive functioning in 8- to 13-year-old children. Three tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB), two tasks from the NEPSY battery and some additional executive function (EF) tests were administered to 108 children. In line with earlier work, modest correlations among EF measures were obtained (r < .4). Both exploratory and confirmatory factor analyses yielded three interrelated factors, which resembled those obtained by Miyake et al. (2000) and which were—with some reservations—labelled Working Memory (WM), Inhibition and Shifting. Age correlated with performance on most individual EF measures as well as Shifting a…

Are balance problems connected to reading speed or the familial risk of dyslexia?

2011

Aim The aim of this study was to examine the connection between balance problems and reading speed in children with and without a familial risk of dyslexia by controlling for the effects of attention, hyperactivity, and cognitive and motor functioning. Method The prevalence of balance problems was studied in 94 children (48 females, 46 males) with a familial risk of dyslexia (at-risk group) and 85 children (38 females, 47 males) without a risk of dyslexia (comparison group). Further, the relationships between balance problems (at age 8y 6mo), reading proficiency (at age 9y), attention-deficit-hyperactivity disorder (at age 8y), and cognitive (at age 8y 6mo) and motor functioning (at age 6y …

Behavioural correlates of early-treated congenital hypothyroidism

2007

Parents' and teachers' ratings were used to evaluate the behavioural characteristics of children with early-treated congenital hypothyroidism (CH). Comparisons were made between 63 children with early-treated CH and 34 healthy controls at the ages of 7.5 and 9.5 y. Additional comparisons were made between the two largest CH subgroups (thyroid agenesis, thyroid dysgenesis) and controls. The most marked differences were found on the introversion cluster and the motor clumsiness scale within it. Children with CH, particularly those with thyroid agenesis, showed introversion and motor clumsiness rather than social negativity and inattention. It is suggested that this behavioural profile may wel…

The effects of a psychomotor training programme on motor skill development in children with developmental language disorders

1998

Abstract The purpose of this study was to compare the effectiveness of two approaches to movement intervention for children with a combination of language and movement difficulties – a specialist approach labelled psychomotor training and regular PE lessons from trained PE teachers. From a sample of 76 children formally classified as suffering from developmental language disorder, 54 (71%) fell below the 15th percentile on a test of motor competence. These 54 children were then divided into two groups, one of whom received a 10 week psychomotor training programme and the other regular PE lessons. Although all children, regardless of the type of intervention, made progress, the differences b…

A school-based movement programme for children with motor learning difficulty

2006

The study investigated the effectiveness of a school-based movement programme for a population of 5 to 7 year old children. Performance profiles on the Movement ABC were used to classify the children and to assess skill changes over time. Children were assigned to four different groups: motor learning difficulty (n = 10), borderline motor learning difficulty ( n = 5), trained controls ( n = 9), untrained controls ( n = 9). The total programme consisted of 26 weekly sessions. Each one-hour session comprised of structured group play, individualized skill training, and relaxation. The results showed that children with motor learning difficulty improved consistently in the targeted skills. Mos…

Motor problems in children with early-treated congenital hypothyroidism: A matter of failing cerebellar motor control?

1998

This study addresses the question of whether "clumsiness" in children with early treated Congenital Hypothyroidism (CH) might be attributable to cerebellar dysfunction. CH is known to affect rapid perinatal growth of the cerebellum. If this would affect the supposed motor timing function of the cerebellum this should be especially reflected by difficulty in producing fast aiming movements. An experiment was devised in which children made sequences of fast, goal directed movements in order to examine two aspects of fast voluntary movements that are known to be affected by cerebellar injury: dysmetria and dysdiadochokinesis. Three groups of children between the ages of 9 and ii participated: …

An aggression machine v. determinants in reactive aggression revisited

2001

The relations between reactive aggression, situational cues, and emotion regulation were examined by means of the Pulkkinen Aggression Machine (PAM) task. In the PAM, provocation and response were systematically varied under two conditions: the impulsive aggression condition and the controlled aggression condition. In the impulsive condition, no information about the attacker was provided, while in the controlled condition the attackers were specified in terms of sex, age, and physical strength. The task was administered to 109 children aged 8 to 13 years. Boys (n = 61) and girls (n = 48), as well as subgroups of Adjusted (n = 67) and Maladjusted (n = 26) children were compared. The results…
