A study of 60- to 89-mo.-old children's skill at writing numerals

The skill of writing numerals necessitates a certain developmental maturity. Studying the age at which children start to develop this skill and assessing problems they encounter while writing numerals should give direction to their training. From 8 schools a total of 267 children, ages 60 to 89 mo., were asked to write the numerals 1 to 9. Analysis showed that 80% of the children wrote most of the numerals correctly, 15% wrote inverted numerals, 2.0% wrote some numerals as letters, and 4% did not write certain numerals at all. In addition, 64% of children ages 60 to 65 mo. gave correct responses, and the perception of correct responses increased across age groups until 95% were correct in the group who were 84 to 89 mo. There was no significant difference between girls and boys in these writing skills.     

Early communicative gestures and play as predictors of language development in children born with and without family risk for dyslexia

The present study investigated early communicative gestures, play, and language skills in children born with family risk for dyslexia (FR) and a control group of children without this inheritable risk at ages 12, 15, 18, and 24 months. Participants were drawn from the Tromsø Longitudinal study of Dyslexia (TLD) which follows children's cognitive and language development from age 12 months through Grade 2 in order to identify early markers of developmental dyslexia. Results showed that symbolic play and parent reported play at age 12 months and communicative gestures at age 15 months explained 61% of the variance in productive language at 24 months in the FR group. These early nonlinguistic measures seem to be potentially interesting markers of later language development in children born at risk for dyslexia.     

Development of hand preference in the Colorado Adoption Project

A longitudinal study of the development of hand preference in 152 adopted and 120 nonadopted (control) infants measured in natural behavioral situations at both 12 and 24 mo. of age is reported. Significant developmental trends were observed for both increasing strength and direction of handedness. Less than 10% of the infants exhibited a clear preference at 12 mo. of age, whereas about 30% were lateralized at 24 mo., with more boys than girls being left-handed. In contrast, over 90% of the parents of these children (both biological and adoptive parents of the adopted children and parents of the nonadopted children) were lateralized. Perhaps because so few infants were lateralized at either age, parent-offspring resemblances were inconsistent and the number of significant parent/child correlations was about that expected on the basis of chance alone.     

Father-child relationships from the preschool years through mid-adolescence

In this study, we examined variations in fathering and father-child relationships from the children's preschool years through mid-adolescence. One hundred seventy-seven fathers with first-born children ages 4, 8, 12, and 16 years responded to five sets of questionnaires tapping four domains of childrearing: practices, attitudes, parental role involvement, and role satisfaction. A multivariate analysis of variance identified significant variability among the four age groups in fathers' use of acceptance in childrearing practices, role involvement (frequency and task sharing), satisfaction with paternal role performance, and attitudes about the modifiability of child behavior. The results contribute new information about the nature of fathering throughout the childhood years and adolescence and provide additional support for the view of parenting as dynamic and responsive to the developmental level and gender-related characteristics of the child.     

Risk factors and the Child Behavior Checklist in a child mental health center setting

The relationship between risk factors and the severity and type of childhood disorder, as measured by parent-completed Child Behavior Checklists, was examined for 768 children, ages 4–16, seen at a child mental health center. Regression analyses revealed no significant relationships between any combination of risk factors and the total number of behavior problems, internalizing, or externalizing scores for the entire group, males and females separately, or for the age and sex groupings of 6- to 11- and 12-to 16-yearolds. Chi-square tests revealed no relationship of profile type with any risk factor or with total number of risk factors. Implications for broad-based child assessment and risk factor research within a clinical population are discussed.We wish to thank Orin Bolstad, Linda Magnuson, and Julian Taplin for their assistance in this project.     

Correlates of the Temporal Consistency of rsonality Patterns in Childhood

ABSTRACT The temporal consistency of children's personality patterns as measured by the California Child Q-set was investigated in a sample of 151 German children between ages 4 and 6 years, and in a sample of 87 Dutch children between ages 10 and 12 years. Children's personality patterns showed a high interindividual variance of consistency. Correlational analyses revealed that children's ego resiliency predicted the longitudinal consistency of their Q-sort patterns irrespective of variations in age, culture, and type of judge. Itemwise extreme group comparisons of very consistent and very inconsistent children with a middle group showed that consistent children were characterized by culturally desirable traits, and inconsistent children by undesirable traits. The items typical for consistent children changed with age in agreement with the change in major developmental tasks. Discussion focuses on the processes that mediate the positive relations between the temporal consistency of personality, ego resiliency, and the age-appropriateness of personality.     

Maternal sensitivity and overt aggression in young children with Down syndrome

Children with genetic syndromes offer a unique opportunity to combine genetic and environmental approaches to the study of aggression. Children with genetic syndromes associated with developmental delay are at increased risk for behavior problems, but little is known about risk and resilience factors. In this study, we examined maternal sensitivity of mothers of children with Down syndrome using home observations when their children were 2, 3, and 5 years old, and relations with maternal reports and observations of overt aggression at school at age 5. Maternal sensitivity at ages 2 and 3 years did not significantly predict child aggression at age 5, but low maternal sensitivity at age 5 was significantly related to overt aggression at both home and school. By replicating and extending earlier work, this study informs developmental theory and identifies an important maternal variable related to aggression in children with Down syndrome.     

Sensibilité développementale théorique et empirique des items de la Batterie d’Évaluation Cognitive et Socio-émotionnelle (BECS) pour l’évaluation du développement psychologique de très jeunes enfants au développement typique

The Social and Cognitive Evaluation Battery (SCEB) is an instrument specifically created for the examination of pre-school and school-aged children with autism and intellectual disability and recommended by the French High Health Authority (HAS, 2010, 2011, 2012, 2018). The SCEB explores 16 functional abilities, in both cognitive and socio-emotional areas and allows the calculation of domains and areas developmental levels and heterogeneity indices for the global, cognitive and socio-emotional areas. Each of the 16 domains of the SCEB includes behavioral items hierarchized into 4 developmental levels corresponding to 4 age periods (level 1: 4–8 months; level 2: 8–12 months; level 3: 12–18 months; level 4: 18–24 months). The child's assessment provides a profile of the 16 levels of cognitive and socio-emotional development that can be interpreted within the framework of Piaget's (1977) and Fisher's (1980) theory. The study tests the developmental sensitivity of level scores and their adjustment to chronological ages and developmental ages assessed with the Brunet-Lézine Scale for 65 young typical developmental French children aged from 4 months to 24 months. The results show high sensitivity of scores and satisfactory adjustment to chronological and developmental age differences. Normative benchmarks are also given for indices of heterogeneity of development profiles, heterogeneity that decreases with age. Thus, the scores are interpretable in reference to theoretical models and can be used for the study of all developmental characteristics in infant and toddlers’ children with and without neurodevelopmental disorder.     

Developmental sequences in the age of onset of disruptive child behaviors

Retrospective and prospective reports of the onset of disruptive child behaviors were analyzed in a sample of clinic-referred boys. The younger boys (ages 7–9 years), compared with the older boys (ages 10–12 years), showed the highest level of disruptive behavior and, judging from mothers' reports, had the fastest progression of onsets from less serious to more serious problem behaviors. Despite some overlap, developmental sequences in problem behavior within the domains of hyperactivity/inattention, oppositional behavior, and conduct problems were similar across the two age groups. This was also the case for developmental sequences of overt or confrontive problem behaviors and covert or concealing conduct problems. Sequences of the onset of oppositional behavior and conduct problems were validated through prospective data, based on the information from mothers, teachers, and boys themselves. The implications of the findings are discussed for the formulation of developmental pathways of behavior and the analysis of causal factors.     

Comparability of the Vineland Social Maturity Scale and the Vineland Adaptive Behavior Scale--survey form with infants evaluated for developmental delay.

The Vineland Social Maturity Scale and its revision, the Vineland Adaptive Behavior Scale-Survey Form, were evaluated with infants referred for suspected developmental delay. Since the latter is being used more often by psychologists in evaluation and placement of children in the age group of birth to two years, comparative studies must ensure appropriate placement of children observed to have developmental delays. The present study indicated significantly higher over-all adaptive functioning on the Vineland Adaptive Behavior Scale-Survey Form for 33 black and 11 white infants of mean age 12 mo. than on the original Vineland scales. Substituting the Survey Form for the original Vineland scales when evaluating developmentally delayed infants is questionable. These results are also noteworthy in that children whose Vineland Social Maturity scaled scores make them eligible for special services would be excluded if the revised form were used in the evaluation process.     

A developmental origins perspective on the emergence of violent behavior in males with prenatal substance exposure

Children with prenatal substance exposure are at increased risk for externalizing behavior problems and violence. However, the contribution of early life experiences for placing these individuals at risk is not well understood. Utilizing a sample of 1,388 children with prenatal substance exposure from the Maternal Lifestyle Study, we attempt to shed light on these contributing factors by examining the impact of infant temperament, maternal sensitivity, and early life stress on the expression of violent behavior at ages 12 through 14 years. Males may be more at risk for increases in violent behavior in early adolescence through a number of early life experiences, such as variability in responses to maternal flexibility and engagement related to individual differences in temperament, as well as exposure to early adversity. Comparing two prevailing developmental theoretical frameworks, deficit models and differential susceptibility, we aim to understand the developmental origins of violent behavior in males by identifying children who may be most susceptible to early caregiving experiences.     

Visual search by children: the effect of background variation and the use of visual cues

A visual search task was used to assess developmental changes in children's selective attention to specified portions of a visual display. Seven-, nine-, and twelve-year-olds searched for a target letter in matrices of letters, each of which was centered in a form. On each matrix the forms were uniform or they varied in color, shape or both color and shape. The children searched with either no cues or with color or shape cues that could be used to restrict and speed their search. In all conditions search speed increased with age. Comparisons among conditions revealed three different age trends. With no cues children of all ages were slowed comparably by variation in background forms. With color cues all children increased their search speeds relative to no-cue speeds, suggesting selective fixation, but the 12-year-olds benefited most from the cues. With shape cues the search speed of 9- and 12-year-olds was slowed while that of 7-year-olds was either unchanged or was slowed only slightly. These different trends caution against overly general statements of changes with age in selective attention, and highlight the need to consider both particular task requirements and the processes used by subjects of different ages in tasks requiring selective attention.     

汉语发展性阅读障碍儿童的不同视野注意能力

以某城市小学三至五年级的学生为研究对象,筛选出发展性阅读障碍和同年龄对照组两组儿童,采用不同视角的刺激探测任务初步探查了汉语发展性阅读障碍儿童的不同视野注意能力及特点。研究使用圆点、数字和汉字三种刺激类型并设置了3°,12°,17°三种视角条件。结果发现,在数字和汉字条件下,汉语发展性阅读障碍儿童对刺激探测的反应时显著长于同年龄对照组儿童,说明在加工复杂刺激时,汉语发展性阅读障碍儿童可能存在知觉加工迟缓的缺陷。但是,汉语发展性阅读障碍儿童并没有表现出扩散的视觉空间注意模式,即更多地注意外侧视野的信息。汉语发展性阅读障碍儿童的视觉空间注意模式与正常儿童相似,表现为随着视角的增加,正确率降低,反应时延长。     

Hand preference as related to development and behavior in infancy

55 healthy infants were assessed for their developmental and behavioral patterns at the age of 9 mo. Hand preference was assessed at 20 mo. of age. The distribution of hand preference showed 12 were right-handed, 11 left-handed and 23 ambidextrous. This distribution appears shifted more to the left than that reported for older children. Although their data were based on different tests not appropriate for 9-mo.-old infants, ambidexterity appeared to reflect part of the hand-preference continuum. No significant relationship between hand preference and developmental attainments was noted. Perhaps a larger sample would provide a clear developmental behavioral pattern and hand preference in infancy.     

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.     

Behavior Problems in Young Children With or At Risk for Developmental Delay

We examined the prevalence of behavior problems and their relationship to child, parent, and family factors in 76 children with or at risk for developmental delay. Parents reported that 42% of the children had behavior problems. Child Behavior Checklist (CBC) scores revealed that 25% of the sample scored above the borderline cutoff. Although the total, externalizing, and internalizing mean CBC scores did not differ from the normative group (same-aged peers without developmental delay), each of the syndrome subscales was significantly higher in the study group. The Reiss Scales for Children's Dual Diagnosis revealed that, as compared to older children (4 years) with developmental delay, the study sample scored significantly lower on the total score and 8 of the 10 subscales. Increased CBC total scores were significantly related to dependency and management of the child, birth weight, gestational length, paternal illness, maternal depression, perceived personal burden of care, maternal escape-avoidance coping strategy, family disharmony, and financial stress. CBC total scores were significantly negatively correlated with being of a multiple birth, paternal education, maternal employment, two-parent family, family social support, and family income. Multiple regression analyses revealed that an empirically-derived combination of child, parent, and family variables accounted for 31% of the variance in CBC total scores. Our findings suggest that 2-year old children with or at-risk for developmental delay may already be showing signs of increased risk of behavior problems relative to peers without developmental delay. We identified several child, parent, and family variables that may help to pinpoint children at increased riskxs for psychopathology.     

Prevention of anxiety symptoms in children: results from a universal school-based trial

The present study evaluated the effectiveness of a universal school-based cognitive behavior prevention program (the FRIENDS program) for childhood anxiety. Participants were 638 children, ages 9 to 12 years, from 14 schools in North Rhine-Westphalia, Germany. All the children completed standardized measures of anxiety and depression, social and adaptive functioning, coping strategies, social skills, and perfectionism before and after the 10-week FRIENDS program and at two follow-up assessments (6 and 12 months) or wait period. Children who participated in the FRIENDS program exhibited significantly fewer anxiety and depressive symptoms, and lower perfectionism scores than children in the control group at 12-month follow-up. Younger children (9-10-year-olds) displayed treatment gains immediately after the intervention, whereas older children (11-12-year-olds) showed anxiety reduction only at 6- and 12-month follow-up. Perfectionism and avoidant coping acted as mediators of pre- to postintervention changes in anxiety scores. This study provides empirical evidence for the utility of the FRIENDS program in reducing anxiety and depressive symptoms among German children.     

Significance of Childhood Conduct Problems to Later Development of Conduct Disorder Among Children With ADHD: A Prospective Follow-Up Study

This study investigates whether low to moderate levels of childhood oppositional defiant disorder (ODD) and conduct disorder (CD) behaviors contribute to the development of clinically diagnosed CD in adolescence, in children with attention deficit hyperactivity disorder (ADHD). Participants were 207 White boys (ages 6-12) with ADHD free of conduct disorder diagnoses. Parent and teacher ratings were obtained. Participants were assessed at mean age 18 by clinicians blind to childhood status. A non-ADHD group (recruited in adolescence) was also studied. ODD behavior ratings did not predict CD in adolescence, whereas CD behavior ratings did. No single ODD or CD behavior predicted adolescent outcome. ADHD probands with very low ratings (Not at all, Just a little) by parents and teachers on all CD behaviors were still at significantly increased risk for CD in adolescence, compared to non-ADHD controls. The same relationships were found between childhood ODD and CD behaviors, and antisocial personality disorder in adulthood (mean age, 25). We conclude that childhood ADHD is a developmental precursor of later antisocial disorder, even in the absence of comorbid ODD or CD in childhood. However, low levels of CD-type problems are not innocuous, because they predict later CD among children with ADHD without comorbid CD.     

Screens across the pond: Findings from longitudinal screen time research in the US and UK

Digital media are increasingly pervasive in the lives of young children. This increase in the availability of digital media might have long-run implications for child development; however, it is too soon to definitively conclude the direction of effects. In part due to this lack of certainty, leading health organizations have chosen to make different recommendations to parents of young children: Many international health organizations (e.g., the American Academy of Pediatrics, World Health Organization) recommend very young children be limited to under one hour of screen time daily, whereas others (e.g., Royal College of Paediatrics and Child Health) have intentionally opted not to make recommendations about specific limits. These guidelines might contribute to parents in different countries making meaningfully different choices about children’s use of digital media. Using a sample of N = 303 families recruited in Cambridgeshire, England and New York City prior to the birth of couples’ first child, we explore predictors of digital media use across the first two years of life. Data were collected when children were 4, 14, and 24 months of age. Results of latent growth curve analyses show that generally, children spend more time engaging with digital media as they grow older; however, growth mixture models reveal most children fit into one of two classes: One group of children (High Media Users; 52.2 %) engages with a substantial amount of digital media, whereas the other (Low Media Users; 48.8 %) engages with relatively little. Children in the US were approximately 30 % more likely to be in the Low Media Users group and there were no differences in group membership on the basis of parents’ psychosocial wellbeing. While these differences could be due to a number of factors, these findings may reflect the power of pediatric recommendations.     

Trajectories of Oppositional Defiant Disorder Irritability Symptoms in Preschool Children

This study traces the developmental course of irritability symptoms in oppositional defiant disorder (ODD) from ages 3–5 and examines the psychopathological outcomes of the different trajectories at age 6. Method. A sample of 622 3-year-old preschoolers (311 were boys), followed up until age 6, was assessed yearly with a semi-structured diagnostic interview with parents and at age 6 with questionnaires answered by parents, teachers and children. Results. Growth-Mixture-Modeling yielded five trajectories of irritability levels for the whole sample (high-persistent 3.5 %, decreasing 3.8 %, increasing 2.6 %, low-persistent 44.1 % and null 46.0 %). Among the children who presented with ODD during preschool age, three trajectories of irritability symptoms resulted (high-persistent 31.9 %, decreasing 34.9 % and increasing 33.2 %). Null, low-persistent and decreasing irritability courses in the sample as a whole gave very similar discriminative capacity for children’s psychopathological state at age 6, while the increasing and high-persistent categories involved poorer clinical outcomes than the null course. For ODD children, the high-persistent and increasing trajectories of irritability predicted disruptive behavior disorders, comorbidity, high level of functional impairment, internalizing and externalizing problems and low anger control at age 6. Conclusions. Irritability identifies a subset of ODD children at high risk of poorer longitudinal psychopathological and functional outcomes. It might be clinically relevant to identify this subset of ODD children with a high number of irritability symptoms throughout development with a view to preventing comorbid and future adverse longitudinal outcomes.
