A comparison of objective measures of activity and distractibility in hyperactive and nonhyperactive children

In a 15-minute free-play and a 5-minute test session, 13 measures of activity, distractibility, and parental ratings of activity were obtained on three groups of children, consisting of 16 boys referred to a psychological services center for evaluation of possible hyperactivity, 16 referred to that same center for problems other than hyperactivity, and 20 obtained from the local community. Subjects were boys with average intelligence between the ages of 4 and 12 years. Results indicated that the multiple measures of activity and distractibility had significant but relatively low order correlations among themselves. These relationships varied as a function of the subject group. However, there was no sonsistent relationship between the measures of activity and distractibility. The pattern of relationships obtained suggested that both activity level and distractibility are not homogeneous, unidimensional constructs. Results also indicated that boys referred for hyperactivity displayed greater wrist activity in free play, tended to display greater ankle activity in free play, had significantly correlated wrist and ankle activity, and were rated by their parents as more active than other children. This pattern suggested a global restlessness in children referred for hyperactivity that distinguishes them from other children.     

Relationship between fine/gross motor skills and language and math development in Colombian Caribbean children: A study in Barranquilla

Literature suggests that motor skills are associated with other areas of development or domains, such as language and math, especially at early ages. These results are mainly based on studies developed in medium-to-high sociocultural contexts. Thus, this study was conducted in a medium-to-low-income area. The aim was to know the 4–5 years old children's motor development (both fine and gross motor skills), and its relation to language and mathematical development. A total of 219 Colombian Caribbean children (105 boys and 114 girls) aged 4 and 5 years participated in this study. Results revealed higher motor skills among girls, although differences by gender were not notable. Positive and significant correlations were found between motor skills and language and mathematical skills, although most of the correlations were weak or moderate. Also, it was observed that fine motor skills were less related to language or mathematical development in comparison with gross motor skills, especially among boys. These results suggest that among Colombian Caribbean children gross motor skills could have a higher influence on the development and acquisition of some language and mathematical skills in comparison with fine motor skills.     

A SOCIAL ECOLOGY OF HYPERACTIVE BOYS: MEDICATION EFFECTS IN STRUCTURED CLASSROOM ENVIRONMENTS

Hyperactive boys on methlyphenidate (Ritalin), hyperactive boys on placebo, and comparison boys were observed in quasi-naturalistic classroom settings. Ambient stimulation (quiet versus noisy conditions) and source of regulation (self-paced versus other-paced activities) were varied in a 2 × 2 design. Compared to their peers, hyperactive boys on placebo showed lower rates of task attention and higher rates of gross motor movement, regular and negative verbalization, noise-making, physical contact, social initiation, disruption, and acts that were perceived as energetic, inappropriate, or unexpected. Self-paced activities resulted in increased rates of verbalization, social initiation, and high-energy episodes. High ambient noise levels reduced task attention and increased the rates of many other behaviors including verbalization, physical contact, gross motor movement, and high-energy acts. Medication-by-situation interactions emerged for both classroom dimensions, with hyperactive boys on placebo being readily distinguishable from their peers under some classroom conditions and indistinguishable under other conditions. Moderate relationships were found between teacher ratings and many individual behavior categories. Discussion focused on (a) the merits and limitations of a social ecological research perspective, and (b) the implications of these findings for the design of intervention strategies.     

Aggression and Sociometric Status among Peers: Do Gender and Type of Aggression Matter?

The connections between the use of different types of aggression (direct physical, direct verbal, and indirect) and sociometric status among same-sex and opposite-sex peers were studied. The subjects were 209 ninth-grade adolescents. Although an adolescent's aggression in general was related to being rejected by peers, a different picture emerged when the shared variance between types of aggression was controlled: The partial correlations showed that when the level of direct (physical and verbal) aggression was kept constant, increases in indirect aggression did not explain variance in peer rejection scores. On the contrary, the use of indirect aggression contributed (especially among boys) to social acceptance by peers. The direct (physical and verbal) forms of aggression were unrelated to adolescents' social acceptance scores. No clear differences were detected between girls' and boys' acceptance or rejection of their aggressive peers, despite the finding that boys seemed to tolerate indirect aggression better than girls did.     

Effect of noise distractibility on the spans of apprehension of hyperactive boys

Denton and McIntyre (1978), using a forced-choice letterrecognition procedure, demonstrated increasing reductions in the spans of apprehension of hyperactive as compared to normal boys when a signal letter was embedded within an increasing number of noise letters. In the present study, the effect of variations in the amount of physical signal-noise similarity and noise redundancy upon the spans of apprehension of hyperactive and normal boys was compared to determine whether noise letters act as more potent distractors for the hyperactive boys. Results indicated the spans of both groups were effected equivalently by variations in signal-noise similarity and noise redundancy. No evidence for a distractibility explanation was obtained.     

Effects of Peer Victimization on Child Emotional and Behavioral Difficulties: The Moderating Role of Parenting

While the harmful effects of peer victimization have been well documented, there is limited research on the parental behaviors as potential moderators of victimization and child mental health outcomes. The current study examined the moderating effects of parental warmth, parental rejection, and child gender on the relation between peer victimization and child mental health difficulties, i.e., emotional and behavioral difficulties. Participants included 425 Chinese elementary school children in grades 3 to 6 (M_age?=?10.59, SD_age?=?1.11), who self-reported on peer victimization experiences, perceived parental warmth and rejection, and mental health difficulties. Data were collected at two-time points, six months apart. Victimization and parental rejection positively predicted child emotional and behavioral difficulties, while parental warmth negatively predicted child emotional and behavioral difficulties at both time points. Victimization significantly predicted emotional difficulties (at time 1) and behavioral difficulties (at time 2) for girls, but not boys. In addition, gender moderated the interaction of victimization and parental rejection in predicting child behavioral difficulties at time 1, i.e., parental rejection exacerbated the effects of peer victimization on behavioral difficulties for girls only. Findings highlight the need to target bullying prevention efforts, and underscore the importance of evaluating peer and parental factors while working with children with emotional and behavioral issues.

     

Child dissociation and the family context

Forty boys and their parents completed measures of dissociation, state anxiety, and perceptions of parental behaviors. Mothers completed a behavior problems checklist about their sons. The results indicated a correspondence between fathers' and sons' dissociation scores. In addition, links were found between parental dissociation, parental inconsistency and rejection, and child dissociation. The findings are discussed in the context of several recently proposed models of the etiology of child dissociative disorders.     

Behavior Problems of preschool children: Dimensions and congenital correlates

Factor analysis of a revised Behavior Problem Checklist for a sample of preschool children yielded six oblique primary factors and two orthogonal second-order factors. Scores on these factors were correlated with activity level, gross- and fine-motor incoordination, minor physical anomalies, and sociability. There were sex differences and factor differences in the resulting patterns of correlations. The patterns of correlations also indicated that the six primary factors could be collapsed into two broad (Conduct and Personality) and two narrow (Distractibility and Attention Seeking) factors.     

Minor physical anomalies in exceptional children: A review and critique of research

The study of the relationship between physical characteristics and behavior is placed in historical context. Current research concerned with the implications of minor physical anomalies is reviewed. Anomalies, measurement considerations, relationship between anomalies and selected characteristics, methodological issues, and underlying assumptions are examined. Conclusions and suggestions for future research are provided.     

Gender Differences in Predicting Antisocial Behaviors: Developmental Consequences of Physical and Relational Aggression

This study investigated gender differences in the relationship of early physical and relational aggression to later peer rejection and overt and covert antisocial behaviors. Significant gender differences were found indicating physically aggressive boys were more likely than girls to experience later peer rejection. Early physical aggression was related to later overt antisocial behavior for boys and girls, and more strongly for girls than for boys. Early relational aggression was not associated with later forms of antisocial behavior. In the context of early physical aggression, for boys and girls peer rejection generally served to increment risk for later overt and covert antisocial behavior in an additive fashion. The data suggest some gender specificity in the social risk processes associated with the development of early overt and covert antisocial behaviors.     

Relationships between physical activity and motor skills in middle school children

The purpose of this study was to examine the relationships between physical activity measured as pedometer steps and performance on three motor skill tests. A secondary purpose was to determine if middle school children are meeting the recommendation for the number of daily steps. A sample (n =217) of 6th, 7th and 8th grade students participated. Each subject wore a Digi-Walker pedometer for three consecutive days. Subjects additionally recorded their pedometer steps in two 45 min.-physical education classes. There were strong significant correlations between daily steps taken by boys and girls, pedometer steps during physical education class and the AAHPERD Passing Test and the Bass Stick Balance. Similar correlations were weaker for the Side-Step Agility Test. Multivariate analysis of variance was utilized to examine variability of the three skills test by sex and year in school. Differences between students in Grades 7 and 8 on the AAHPERD Passing Test were significant. In addition, significant differences between daily pedometer steps and steps during physical education between Grades 6 and 7 were observed. Boys and girls had similar means on the AAHPERD Passing Test and Bass Stick Balance Test, but not on the Side-Step Agility Test. Scores on the three movement skills tested in this study were not strongly related to physical activity of the entire sample. Steps taken by middle school children appear not to be related to these measures of motor skills.     

The Protective Role of Teacher Preference for At‐Risk Children's Social Status

Aggressive behaviors have been associated with social costs (e.g., rejection) and benefits (e.g., popularity) in previous studies. The current study sought to examine the moderating effect of teacher preference on the association between distinct forms of aggressive behavior (i.e., physical aggression and relational aggression) and social status (i.e., rejection and popularity), and to explore whether these associations differed for boys and girls. Fourth and fifth grade students (N = 193) completed peer nomination procedures to assess rejection and aggressive behavior and teachers provided self‐reports of their preferences for their students. Findings indicated that relationally aggressive girls were more likely to be popular with their peers when their teachers also liked them. In addition, both relationally and physically aggressive girls were less likely to be rejected by their peers when their teachers liked them. Although physical aggression was most strongly associated with rejection among boys whose teachers liked them, relational aggression predicted popularity among boys whose teachers disliked them. Results suggest that teacher preferences may be a particularly important factor contributing to both physically and relationally aggressive children's social status (e.g., rejection and popularity), especially for girls.

Associations of physical activity and gross motor skills with executive function in preschool children from low‐income South African settings

Executive function is foundational for cognitive development. Previous research has shown both gross motor skills and physical activity to be related to executive function. However, evidence for these relationships in the preschool years, as well as in low‐ and middle‐income countries is lacking. Therefore, this study aimed to investigate the relationships between components of executive function (inhibition, shifting and working memory) and gross motor skills (locomotor skills and object control skills) in a sample of preschool children from urban and rural low‐income settings in South Africa. Results revealed that inhibition and working memory, but not shifting, were associated with gross motor skills. More specifically: inhibition was associated with both locomotor [β = 0.20, p = 0.047] and object control skills [β = 0.24, p = 0.024], whereas working memory was only associated with locomotor skills [β = 0.21, p = 0.039]. Physical activity was not associated with inhibition and shifting but was negatively associated with working memory. These results elaborate a growing evidence base linking executive function and gross motor skills in the early years, and it is the first to look at specific associations of locomotor and object control skills with executive function in the South African context (a low‐ and middle‐income country).     

Reactive and proactive aggression in childhood: Relations to peer status and social context dimensions

Although there has been an accumulation of evidence to suggest a link between peer-directed aggression and social rejection, little attention has been given to the relations between specific subtypes of aggressive behavior and social rejection. The purpose of this investigation was to examine the relations between two subtypes of aggressive behavior (reactive and proactive aggression) and children's classroom peer status. The reciprocity of each of these subtypes of aggressive behavior and the social contexts in which these behaviors occur were also examined. Assessments of each of these forms of aggression among 70 boys (ages 5 and 6) were conducted using direct observations and teacher ratings. In general, directing reactive aggressive behavior toward peers was associated with social rejection, while utilization of instrumental aggression was positively related to peer status. The findings also indicated that directing proactive forms of aggression toward peers was related to being the target of proactive aggression. Finally, among older boys, both subtypes of aggression were more likely to occur during rough play than during any other type of play activity.     

Profiling Movement and Gait Quality Characteristics in Pre-School Children

There is a dearth of suitable metrics capable of objectively quantifying motor competence. Further, objective movement quality characteristics during free play have not been investigated in pre-school children. The aims of this study were to characterize children's free play physical activity and investigate how gait quality characteristics cluster with free play in pre-school children (3–5 years old). Sixty-one children (39 boys; 4.3 ± 0.7 years, 1.04 ± 0.05 m, 17.8 ± 3.2 kg) completed the movement assessment battery for children and took part in free play while wearing an ankle- and hip-mounted accelerometer. Characteristics of movement quality were profiled using a clustering algorithm. Spearman's rho and the Mann-Whitney U tests were used to assess relationships between movement quality characteristics and motor competence classification differences in integrated acceleration and spectral purity, respectively. Significant differences were found between motor competency classifications for spectral purity and integrated acceleration (p < .001). Spectral purity was hierarchically clustered with motor competence and integrated acceleration. Significant positive correlations were found between spectral purity, integrated acceleration and motor competence (p < .001). This is the first study to report spectral purity in pre-school children and the results suggest that the underlying frequency component of movement is clustered with motor competence.     

Ecological validity of the German Bruininks-Oseretsky Test of Motor Proficiency – 2nd Edition

The diagnosis of Developmental Coordination Disorder (DCD) is based on poor motor coordination in the absence of other neurological disorders. In order to identify the presence of movement difficulties, a standardised motor assessment is recommended to determine the extent of movement problems which may contribute to deficits in daily task performance. A German version of the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (German BOT-2) was recently published. This study aimed to determine the ecological validity of the German BOT-2 by considering the relationship between assessment of fundamental motor skills with the BOT-2 and performance of everyday motor activities as evaluated by parents. This study used data obtained from the German BOT-2 standardisation study (n = 1.177). Subtests were compared with theoretically corresponding tasks via parental ratings of overall fine and gross motor abilities and performance in six typical motor activities. Non-parametric Jonckheere Terpstra test was used to identify differences in ordered contrasts. Subtests reflecting ‘Strength’, ‘Running Speed and Agility’, ‘Upper-Limb Coordination’, ‘Balance’, and ‘Fine Motor Precision’ were associated with parental evaluation of gross motor skills (p < 0.001). The subtest ‘Fine Motor Integration’ significantly correlated with parental ratings of females’ fine motor skills. Parental ratings of males’ fine motor skills were associated with three further subtests. Regarding everyday motor activities, the first three fine motor BOT-2 subtests were associated with parent evaluations of drawing, writing and arts and crafts (p < 0.001). Gross motor subtests of ‘Bilateral Coordination’ and ‘Balance’ showed no relationship to bike riding or performance in sports. Subtests of ‘Upper-Limb Coordination’ and ‘Strength’ showed significant correlations with sports, ball games and cycling. The results of this study suggest that the closer the proximity in the nature of the motor skills assessed in the German BOT-2 to daily motor tasks, the stronger the relationship between the clinical test and parental report of everyday performance of their child. The body functions tested in the German BOT-2, and hypothesized to underpin certain skills, were not automatically relevant for specific activities undertaken by German children. Future research should investigate the relationships of the various BOT-2 constructs for diagnosis of DCD.     

The Moderation Role of Self‐perceived Maternal Empathy in Observed Mother–Child Collaborative Problem Solving

Based on L. S. Vygotsky's sociocultural theory, previous scaffolding studies have examined some factors associated with adjustment of parental support during collaborative problem solving. However, a factor that remains unexplored in the literature is the potential relationship between parental empathy and parental support in collaborative problem solving. The present study addresses this question through the observation of 45 preschool children and their mothers cooperating in a problem‐solving task with two levels of difficulty. Teachers rated the children's fine motor skills, and sampled mothers reported their empathy levels towards their children. Consistent with the notion of scaffolding, negative correlations were found between observed maternal verbal support (cognitive, autonomy, and emotional) and child age, and between observed maternal cognitive support and teacher reports of child motor skills. An analysis of covariance revealed significant empathy‐by‐difficulty interactions for physical and cognitive support after controlling for the effect of child motor skills. Implications of these findings are discussed in terms of the role of child motor skills and the importance of parental empathy in collaborative problem solving.

Emotional facial expressions differentially influence predictions and performance for face recognition

The relative contribution of child and parent trait anxiety on paternal and maternal controlling behaviour was examined. Thirty-seven children, aged 8–11 years, completed two difficult Tangram puzzles, one with their father and one with their mother. Videotapes of the parent–child interactions were rated on parental control and child dependent and withdrawn behaviour. Results indicated that, opposite to expectations, higher mother and father trait anxiety was associated with lower levels of parental control, and that the relation between parent trait anxiety and parental control was curvilinear. Furthermore, a significant stronger effect between child trait anxiety and parental control was found for boys than for girls. Moreover, more child withdrawal during the parent–child interaction was related to more parental control. The findings offer new insights, which may guide future theories on child and parent anxiety and parental control. Specifically, the role of parent and child gender need further conceptualisation and research.     

Behavior Problems and Peer Rejection in Preschool Boys and Girls

The authors tested the hypothesis that deviant behaviors within a preschool peer group would be linked with peer rejection, irrespective of child gender. Seventy-six children, aged 3 to 5 years, participated. Teachers rated children's behavior on the Child Adaptive Behavior Inventory, and children provided sociometric ratings. For a subsample of children (n = 47), observers coded aggressive, noncompliant, and withdrawn behavior using a time-sampling system. For both boys and girls, noncompliance, hyperactivity, and social withdrawal were associated with peer rejection; overt aggression was associated with peer rejection for boys, but not for girls. Analysis revealed that approximately half of the variance in sociometric and teacher ratings of peer rejection was accounted for by aggression and social withdrawal for both boys and girls. The results suggest that the association between behavior problems and peer rejection emerges at a very early age.     

Testing the Direction of Longitudinal Paths between Victimization,Peer Rejection,and Different Types of Internalizing Problems in Adolescence

The transition to secondary school is accompanied by the fragmentation of peer groups, while adolescents are also confronted with heightened incidents of bullying and increased levels of internalizing problems. Victimization, peer rejection, and internalizing problems are known to be interrelated, but how they influence each other over time remains unclear. We tested the direction of these associations by applying a cross-lagged path model among a large sample of Finnish adolescents (N = 5645; 49.1 % boys; M age at T1 = 14.0 years) after they transitioned to secondary school (grades 7–9). Self-reported depression, anxiety, and victimization and peer-reported rejection were measured 3 times over the course of 1 year. Results showed that depression was predictive of subsequent victimization for both boys and girls, in line with a symptoms-driven model; for girls, anxiety was reciprocally related to victimization, in line with a transactional model; for boys, victimization was related to subsequent anxiety, in line with an interpersonal risk model. Peer rejection was not directly related to depression or anxiety, but among girls peer rejection was bi-directionally related to victimization. Overall, our results suggest that associations between internalizing problems and peer relations differ between depression and anxiety and between genders. Implications for practice and directions for future research are discussed.
