The gender self-concept profiles of 128 adolescents (107 males) whose persistent behaviour problems led to suspension from school were investigated. Establishing the students' percentile ratings in the 11 subscales of the Self-Description Questionnaire overcame previous methodological weaknesses. For boys and girls Physical Appearance, Opposite-sex Relationships, and Honesty and Trustworthiness were in the average range, but Parent Relationships, General Self, and General School self-concepts were low. Only girls were low for Same-sex Relationships and Emotional Stability. The profiles suggest that boys' antisocial behaviours are associated with striving for a masculine self-image, but girls' antisocial behaviours are associated with greater social marginalisation. The issues of multi-focused interventions, prosocial role models, the particular needs of girls, and the relationship between self-control, self-enhancement, and reputation enhancement theories are discussed.

This paper reports the literacy skills of 63 children selected as being at genetic risk of dyslexia compared with 34 children from families reporting no history of reading impairment. Fifty-seven per cent of the at-risk group were delayed in literacy development at 6 years compared with only 12% of controls. The “unimpaired” at-risk group were not statistically different from controls on most cognitive and language measures at 45 months, whereas the literacy-delayed group showed significantly slower speech and language development, although they did not differ from controls in nonverbal ability. Letter knowledge at 45 months was the strongest predictor of literacy level at 6 years. In addition, early speech and language skills predicted individual differences in literacy outcome and genetic risk accounted for unique variance over and above these other factors. The results are discussed in terms of an interactive developmental model in which semantic and phonological skills support early reading acquisition.

This longitudinal study is part of a series examining the relationships between maternal mood, feeding practices, and infant growth and development during the first 6 months of life in 226 well-nourished mother-infant dyads in Barbados. In this report, we assessed maternal moods (General Adjustment and Morale Scale and Zung Depression and Anxiety Scales), feeding practices (scales describing breast-feeding and other practices associated with infant feeding in this setting), and infant cognitive development (Griffiths Mental Development Scales). Multivariate analyses, with and without controlling for background variables, established significant relationships between maternal moods and infant cognitive development. Infants of mothers with mild–moderate depression had lower Griffiths scores than infants of mothers without depression. Maternal depressive symptoms and lack of trust at 7 weeks predicted lower infant social and performance scores at 3 months. Maternal moods at 6 months were associated with lower scores in motor development at the same age. Although no independent relationships emerged between feeding practices and infant cognitive development, the combination of diminished infant feeding intensity and maternal depression predicted delays in infant social development. These findings demonstrate the need to carefully monitor maternal moods during the postpartum period, in order to maximize the benefits of breast-feeding and related health programs to infant cognitive development.

Phonological awareness is important for reading development in hearing children, in whom it develops at the three consecutive levels of the syllable, rhyme, and phoneme. Deaf children typically have literacy difficulties, and previous research has been equivocal about whether deaf children can develop phonological awareness. Three experiments are presented that investigate the phonological skills of deaf children (mean age 11 years) at the three linguistic levels of syllable, rhyme, and phoneme. The first experiment showed that deaf children's syllable awareness can be equivalent to that of chronological age-matched hearing controls. In the second experiment, deaf children's ability to make rhyme judgements was above chance, but poorer than that of younger reading-matched hearing controls. The third experiment showed that deaf children could phonologically recode nonsense words at a level above chance, suggesting that they could draw on phonemic skills in certain conditions. We conclude that deaf children can develop phonological awareness, but that their phonological skills lag those of hearing children and may develop in different ways. Differences between our tasks and those used in other studies are discussed.

Although tests of young children's understanding of mind have had a remarkable impact upon developmental and clinical psychological research over the past 20 years, very little is known about their reliability. Indeed, the only existing study of test–retest reliability suggests unacceptably poor results for first-order false-belief tasks (Mayes, Klin, Tercyak, Cicchetti, & Cohen, 1996), although this may in part reflect the nonstandard (video-based) procedures adopted by these authors. The present study had four major aims. The first was to re-examine the reliability of false-belief tasks, using more standard (puppet and storybook) procedures. The second was to assess whether the test–retest reliability of false-belief task performance is equivalent for children of contrasting ability levels. The third aim was to explore whether adopting an aggregate approach improves the reliability with which children's early mental-state awareness can be measured. The fourth aim was to examine for the first time the test–retest reliability of children's performances on more advanced theory- of-mind tasks. Our results suggest that most standard and advanced false-belief tasks do in fact show good test–retest reliability and internal consistency, with very strong test–retest correlations between aggregate scores for children of all levels of ability.

This study explored the links between the development of language and the development of social cognition. Measures of language, phonological short-term memory, social cognition, and social competence of two groups of children with specific language impairment (SLI), one group attending a special school, the other attending integrated educational placements, were compared with those of chronological and language age-matched normally developing peers (N = 8 in each group). Significant differences between the scores of normally developing children and the scores of the group of children with SLI who attended the special school were found for social cognition and ratings of social competence. Children with SLI from integrated placements did not differ significantly from other groups on these measures. Assessments of language development and phonological short-term memory were not related to social cognition and social competence. Models of the possible relationship between social cognition and language development in children with SLI are discussed.

This study examined social-emotional functioning in children with Gilles de la Tourette's syndrome (TS) alone and children with TS and Attention Deficit Hyperactivity Disorder (ADHD). In addition, the contribution of family functioning to social competence was examined. Children with a clinical diagnosis of TS were recruited from the Yale Child Study Center TS specialty clinic. Unaffected control children were recruited through newspaper advertisements and announcements within the university and at area schools. The final sample consisted of 72 children (45 boys and 27 girls) between the ages of 8 and 14. Sixteen children met DMS-III-R criteria for TS, 33 children met criteria for TS and ADHD, and 23 children had no psychiatric diagnoses. Children with TS and ADHD evidenced more externalizing and internalizing behavior problems and poorer social adaptation than children with TS only or unaffected controls. Children with TS only were not significantly different from unaffected controls on most measures of externalizing behaviors and social adaptation but did exhibit more internalizing symptoms. Tic symptom severity was not associated with social, behavioral, or emotional functioning among children with TS, even after stratifying by medication status. However, ADHD diagnosis, obsessional symptom severity, and family functioning were significantly associated with social and emotional adjustment among TS children. Moreover, family functioning was associated with social and emotional adjustment even after controlling for TS and ADHD diagnostic status. These findings demonstrate that much of the social and behavioral dysfunction in children with TS is ADHD-specific and children with TS alone have a very different social-emotional profile than do those with TS plus ADHD. Finally, social-emotional adjustment in children with TS is best understood within the family context.

This study investigated the association between reading disability (RD) and internalizing and externalizing psychopathology in a large community sample of twins with (N = 209) and without RD (N = 192). The primary goals were to clarify the relation between RD and comorbid psychopathology, to test for gender differences in the behavioral correlates of RD, and to test if common familial influences contributed to the association between RD and other disorders. Results indicated that individuals with RD exhibited significantly higher rates of all internalizing and externalizing disorders than individuals without RD. However, logistic regression analyses indicated that RD was not significantly associated with symptoms of aggression, delinquency, oppositional defiant disorder, or conduct disorder after controlling for the significant relation between RD and ADHD. In contrast, relations between RD and symptoms of anxiety and depression remained significant even after controlling for comorbid ADHD, suggesting that internalizing difficulties may be specifically associated with RD. Analyses of gender differences indicated that the significant relation between RD and internalizing symptoms was largely restricted to girls, whereas the association between RD and externalizing psychopathology was stronger for boys. Finally, preliminary etiological analyses suggested that common familial factors predispose both probands with RD and their non-RD siblings to exhibit externalizing behaviors, whereas elevations of internalizing symptomatology are restricted to individuals with RD.

Objective: To use the Five Minute Speech Sample (FMSS) to assess Expressed Emotion (EE) in various samples of children with asthma in order to clarify (1) developmental and validity issues for the EE construct and (2) the use of the FMSS technique, specifically, in children with chronic medical illness.

Method: Data were collected on a sample of 84 adolescents with severe, chronic asthma who had failed outpatient management. In addition, a sample of 30 children with asthma, ages 6–9, were recruited from an outpatient pediatric clinic. A comparison sample of 15 children without any chronic illness, ages 6–9, were recruited by notices posted in the community. The primary caregiver of each child was assessed using the FMSS.

Results: FMSS interviews were reliability coded in all samples. Rates of high Criticism (FMSS CRIT), Emotional Overinvolvement (FMSS EOI), and EE were comparable to rates previously reported in child and adolescent samples. Although the validity for ratings of FMSS CRIT was well supported, the validity of FMSS EOI ratings and the overall EE construct were more problematic.

Conclusions: The FMSS is a useful and largely valid measure in children with asthma. Ratings of FMSS CRIT were found to have strong validity. There was little problem shifting the context of FMSS administration from chronic mental to chronic medical illness, but a variety of developmental considerations arose, especially regarding FMSS EOI ratings. Although we raise concerns about viewing EE as a valid construct, it may remain a useful predictive index.

Language impairments are commonly observed among children referred for psychiatric services. The most frequent psychiatric diagnosis of children with language impairment (LI) is Attention Deficit Hyperactivity Disorder (ADHD). It is not clear whether there are differences between children with ADHD and comorbid LI and children with other psychiatric disorders who are also comorbid for LI. In the present study the language, achievement, and cognitive processing characteristics of 166 psychiatrically referred 7–14-year-old children were examined using a 2 × 2 (ADHD, LI) design to examine four groups: children with ADHD+LI, children with ADHD who have normally developing language, children with psychiatric diagnoses other than ADHD with a language impairment (OPD+LI) or without a LI (OPD). Results indicated that children with LI were at the most disadvantage regardless of the nature of the psychiatric diagnosis. Contrary to prediction, working memory measures, used to tap the core cognitive deficit of ADHD in executive functions, were more closely associated with LI than with ADHD. It was concluded that caution must be exercised in attributing to children with ADHD what might be a reflection of problems for children with language impairment generally. As most therapies are verbally based it is notable that language competence is rarely evaluated systematically before such therapies are undertaken.

This study on children with a Pervasive Developmental Disorder (PDD; N = 32), children with developmental language disorder (N = 22), and normally developing children (N = 28) sought to answer questions concerning attachment and autistic behaviour. We could replicate the finding that children with a PDD are able to develop secure attachment relationships to their primary caregiver. Children with PDD who had an insecure attachment showed fewer social initiatives and responses than children with PDD who had a secure attachment, even when the insecurely and securely attached PDD children were matched on chronological and mental age. Children with both a PDD and mental retardation were more often classified as disorganised.

Three findings suggested that a disorganised attachment does not merely reflect the presence of “autistic” behaviour: (1) children with PDD did not reveal higher rates of a disorganised attachment than matched comparison children; (2) having a PDD diagnosis and having a disorganised attachment were found to be associated with opposite effects on an ethological measure of level of behavioural organisation; and (3) a disorganised attachment but not a PDD diagnosis was associated with an increase in heart rate during parting with the caregiver and a decrease in heart rate during reunion.

Factors influencing the rate, form, and severity of phenotypic expression among relatives of autistic probands are examined. Family history data on 3095 first- and second-degree relatives and cousins from 149 families with a child with autism and 36 families with a child with Down syndrome are studied. The results provide further evidence of an increased risk among autism relatives for the broadly defined autism phenotype. Of proband characteristics, severity of autism and obstetric optimality were confirmed as being related to familial loading for probands with speech. There was little variation in loading among probands lacking speech. The type of phenotypic profile reported in relatives appeared little influenced by characteristics of the relative or the proband, except for variation by degree of relative, parental status of relative, and perhaps proband's birth optimality score. Phenotypic rates among parents suggested reduced fitness for the severest and more communication-related forms of expression but not for the more mild and social forms of expression. Patterns of expression within the families did not support a simple X-linked nor an imprinted X-linked mode of inheritance. The basis for sex differences in rates of expression is discussed.

This study explored the claim that individuals with autism and Asperger's disorder tend to process locally rather than holistically. Participants observed a large or “global” number composed of smaller or “local” numbers. The response was contingent upon the identification of either the large stimulus or the small stimuli. Relative to age, sex, and IQ matched controls, global processing in children and adolescents with autism (N = 12) and Asperger's disorder (N = 12) was more vulnerable when the local stimuli were incongruent. The autism group made more global errors than their matched control group, regardless of whether there was local incongruence. In contrast, the Asperger's disorder group made a similar number of global errors as their respective control group. These results were discussed in relation to an “absence of global precedence” notion, “weak central coherence” theory, and right-hemisphere dysfunction. The neurobiological significance of these findings were discussed in the context of a fronto-striatal model of dysfunction.

Thirty hyperactive and 30 non-hyperactive children were confronted with a delay, consisting of a waiting situation of 15 minutes, either with or without extra stimulation provided by the presentation of a videotape. The behaviour of the child during the waiting period was videotaped and later coded by two naive observers. In line with theories that emphasise the stimulation-seeking function of hyperactive behaviours, such as the optimal stimulation account and the delay aversion theory, a group by stimulation effect was hypothesised. For two categories of activity this was found, with ADHD children displaying more activity than non-ADHD children in the no-stimulation but not in the stimulation condition. These data provide support for the stimulation-seeking function of certain features of ADHD hyperactivity.

The present study assesses the effects of demographic risk factors on children's exposure to violence (ETV) and how these effects vary by informants. Data on exposure to violence of 9-, 12-, and 15-year-olds were collected from both child participants (N = 1880) and parents (N = 1776), as part of the assessment of the Project on Human Development in Chicago Neighborhoods (PHDCN). A two-level hierarchical linear model (HLM) with multivariate outcomes was employed to analyze information obtained from these two different groups of informants. The findings indicate that parents generally report less ETV than do their children and that associations of age, gender, and parent education with ETV are stronger in the self-reports than in the parent reports. The findings support a multivariate approach when information obtained from different sources is being integrated. The application of HLM allows an assessment of interactions between risk factors and informants and uses all available data, including data from one informant when data from the other informant is missing.

Using a longitudinal sample of children, this study examined the relation between maternal Expressed Emotion (EE) and mother–child attachment disorganization at age 6 years. A nonclinical sample of 33 children (at ages 12 months and 18 months) from Berlin, Germany participated with their mothers in Ainsworth's Strange Situation. Thirty-two children were again observed with their mothers at age 6 years in a standard laboratory attachment observation. At the time of the 6-year assessment, maternal EE was assessed based on a Five-Minute Speech Sample. Mothers also completed the Life Events Questionnaire, a measure of family stress, and the Present State Examination, a measure of maternal depression.

Maternal Expressed Emotion was significantly linked to mother–child attachment security at age 6 years. Further analyses revealed that High EE was most closely linked to the disorganized attachment pattern at age 6 years, an at-risk attachment pattern that has been associated with intrusive and hostile maternal behavior. The relationship was upheld when other relevant variables, including infant attachment disorganization and a measure of perceived family stress, were simultaneously considered. The study provides independent validation of Expressed Emotion as a measure of relationship quality in early childhood. It also provides a basis for the further investigation of the nature of the relation between maternal Expressed Emotion and attachment disorganization.

Functional imaging studies of developmental dyslexia have reported reduced task-related neural activity in the temporal and inferior parietal cortices. To examine the possible contribution of subtle anatomic deviations to these reductions, volumes were measured for the major lobes of the brain, the subcortical nuclei, cerebellum, and lateral ventricles on magnetic resonance imaging (MRI) scans from 16 right-handed dyslexic men, ages 18 to 40, and 14 matched controls, most of whom had previously undergone PET imaging. A specific decrease in tissue volume was localized to the temporal lobes and was particularly prominent on the left (p < .01). An analysis of tissue composition revealed that this reduction was primarily attributable to decreased gray matter within the left temporal lobe (p < .002). Further segmentation of the temporal lobe showed that this reduction was not confined to the superior temporal gyrus, the primary location of primary auditory cortex. Reductions of temporal lobe gray matter may reflect a regional decrease in neuronal number or neuropil, which in turn may result in reading impairment.

The present study utilised a cognitive paradigm to investigate attentional biases in clinically depressed children and adolescents. Two groups of children and adolescents—clinically depressed (N = 19) and normal controls (N = 26)—were asked to complete a computerised version of the attentional dot probe paradigm similar to that used by MacLeod, Mathews, and Tata (1986). Results provided no support for an attentional bias, either toward depression-related words or threat words, in the depressed group. This finding is discussed in the context of cognitive theories of anxiety and depression.
