Case study: Controlling self-injurious escape behaviors

The present study investigated the effects of a treatment program on the self-injurious behaviors of a 12-year-old autistic male. Initial observations indicated that these behaviors functioned primarily as escape responses to terminate performance demands. For 1 year the subject received general compliance training with the frequency of demands being systematically increased through consecutive treatment weeks. The subject's self-injurious behaviors were no longer reinforced by his escaping from demands nor did they receive social attention. Compliance to demands and appropriate behaviors in general were positively reinforced. The treatment produced substantial reductions in the rates of self-injurious behaviors and increased compliance. Additionally, the intensity of the subject's self-injurious behaviors decreased over the course of treatment. The present study suggests that the treatment approach is a reliable means of not only reducing self-injurious behaviors but also expanding performance repertoires.     

Preventive intervention with latency-aged children of divorce: A replication study

This replication study assessed the efficacy of a school-based preventive intervention for latency-aged children of divorce. The Children of Divorce Intervention Program (CODIP) emphasizes support, identifying and expressing divorce-related feelings, training situationally relevant communication, problem solving, and anger control skills, and enhancing self-esteem. Fifty-four children of divorce participated in the 11-session program conducted in small groups. Their adjustment was contrasted at pre and post with that of demographically matched peers (N = 78) from intact families on teacher, parent, self-report, and group leader measures. Children of divorce were less well adjusted than their peers before the intervention. They improved significantly after the intervention, approaching youngsters from intact families in adjustment status. The replication data support CODIP's efficacy as a preventive alternative for children of divorce. Needed future development and research steps are considered.     

Effectiveness of social skills training with children: A meta-analytic study

This meta-analytic study examined the relative effectiveness of three methods of social skills training with socially isolated children: coaching, interpersonal cognitive problem solving, and modelling. An exhaustive search of the published literature in the area produced a total of 43 studies that met stringent criteria for inclusion in the subsequent analysis. Social skills training produced significant improvements in children's levels of social interaction, sociometric status and cognitive problem solving abilities. No training technique produced a significantly greater improvement than either of the others. Isolated children showed larger increases in their levels of social interaction and sociometric status than non-isolate children. Multi-modal training programmes were recommended to capitalize on the independent therapeutic effects which derive from a number of different social skills training techniques.     

The cognitive consequences of poverty: A neo-Piagetian study with Zulu children

Samples of impoverished Zulu schoolchildren drawn from three age groups were tested repeatedly on the Figural Intersection Test (FIT), a measure of M-power in Pascual-Leone's theory of constructive operators. Results showed an initial underperformance when compared with Canadian and urban Zulu children. This was attributed to the effects of impoverishment. However, impoverished children did acquire the age-related levels of performance after repeated trials, a result consistent with the concept of M-power in the theory of constructive operators.     

Incidence of dysarthria in children with cerebellar tumors: a prospective study

The present study investigated dysarthric symptoms in children with cerebellar tumors. Ten children with cerebellar tumors and 10 orthopedic control children were tested prior and one week after surgery. Clinical dysarthric symptoms were quantified in spontaneous speech. Syllable durations were analyzed in syllable repetition and sentence production tasks. Localization of the cerebellar lesions were defined after manual transfer from individual 2D-MR images onto 3D images of a spatially normalized healthy brain. Cerebellar children showed few and mild clinical signs of dysarthria. No difference was present in the sentence production task compared to controls. In five cerebellar children, syllables were prolonged in the syllable repetition task after surgery. Syllable duration normalized in an additional four-week session in all but one case. The MR-analysis showed that superior paravermal cerebellar areas likely involved in dysarthria in adults (paravermal lobules HVI, Crus I) were not significantly affected. In children, speech impairments appear to be rare after cerebellar surgery because tumors most commonly affect posterior-inferior and medial parts of the cerebellum while critical cerebellar regions are likely spared. The results suggest a similar localization of speech functions in the cerebellum in children and adults.     

fMRI of parents of children with Asperger Syndrome: a pilot study

BACKGROUND: People with autism or Asperger Syndrome (AS) show altered patterns of brain activity during visual search and emotion recognition tasks. Autism and AS are genetic conditions and parents may show the 'broader autism phenotype.' AIMS: (1) To test if parents of children with AS show atypical brain activity during a visual search and an empathy task; (2) to test for sex differences during these tasks at the neural level; (3) to test if parents of children with autism are hyper-masculinized, as might be predicted by the 'extreme male brain' theory. METHOD: We used fMRI during a visual search task (the Embedded Figures Test (EFT)) and an emotion recognition test (the 'Reading the Mind in the Eyes' (or Eyes) test). SAMPLE: Twelve parents of children with AS, vs. 12 sex-matched controls. DESIGN: Factorial analysis was used to map main effects of sex, group (parents vs. controls), and sexxgroup interaction on brain function. An ordinal ANOVA also tested for regions of brain activity where females>males>fathers=mothers, to test for parental hyper-masculinization. RESULTS ON EFT TASK: Female controls showed more activity in extrastriate cortex than male controls, and both mothers and fathers showed even less activity in this area than sex-matched controls. There were no differences in group activation between mothers and fathers of children with AS. The ordinal ANOVA identified two specific regions in visual cortex (right and left, respectively) that showed the pattern Females>Males>Fathers=Mothers, both in BA 19. RESULTS ON EYES TASK: Male controls showed more activity in the left inferior frontal gyrus than female controls, and both mothers and fathers showed even more activity in this area compared to sex-matched controls. Female controls showed greater bilateral inferior frontal activation than males. This was not seen when comparing mothers to males, or mothers to fathers. The ordinal ANOVA identified two specific regions that showed the pattern Females>Males>Mothers=Fathers: left medial temporal gyrus (BA 21) and left dorsolateral prefrontal cortex (BA 44). CONCLUSIONS: Parents of children with AS show atypical brain function during both visual search and emotion recognition, in the direction of hyper-masculinization of the brain. Because of the small sample size, and lack of age-matching between parents and controls, such results constitute a pilot study that needs replicating with larger samples.     

Interhemispheric communication involving multiple tasks: A study of children with dyslexia

The study investigated whether inefficient interhemispheric communication is involved in developmental dyslexia using multiple tasks. A finger localization task, rhyming judgment task, primed lexical decision task, and a visual half-field presentation paradigm were used. Nineteen dyslexic children (mean age = 13.1 years) were compared with 26 chronological age-matched normal children. Although the dyslexic group demonstrated significantly slower and less accurate performance in all three tasks, there was no significant group difference in term of interhemispheric communication. However, priming effects demonstrated by the dyslexic group (p < .05) further indicate that their reading problems may stem from the word retrieval process from the long term memory.     

Caring for children with an intellectual disability: An exploratory qualitative study

This study explored family caregiver experiences of children with an intellectual disability in a rural South African day-care centre. The family caregivers (N = 15; mothers = 60%; age range = 35 to 68 years) completed in-depth interviews regarding their experiences providing care to children with intellectual disability. Data collection and analysis was done using phenomenological methods. The following themes emerged to characterise the family caregiver experiences: deeper understanding of intellectual disability; disability disclosure conditions; and social and economic support needs. Family support emerged as an important factor in the relationship between caregivers’ psychological stress and well-being.     

Spatial cognition and motor development: a study of children with spina bifida

The purpose of this study was to examine the relation between motor development and spatial cognition. The sample was 20 children with Spina bifida (M age: 11.4 yr., SD = 1.7) and 20 healthy children as controls (M age: 11.8, SD = 1.8 yr.). An experimental assessment of motor development in spatial cognition in a simulated virtual maze by school-age children is lacking. In this study children with Spina bifida, who were impaired in walking since birth, completed four visuospatial tasks in a small-scale space (Mental Rotation, Water-Level Task, Embedded Figures Test, Visual Short-term Memory Test), and a spatial behaviour and knowledge task in a virtual maze. These children showed poorer performance than children in the control group on most measures. The results are discussed with respect to theoretical implications and further research.     

Prosodic processing by children: an fMRI study

Prosodic information in the speech signal carries information about linguistic structure as well as emotional content. Although children are known to use prosodic information from infancy onward to assist linguistic decoding, the brain correlates of this skill in childhood have not yet been the subject of study. Brain activation associated with processing of linguistic prosody was examined in a study of 284 normally developing children between the ages of 5 and 18 years. Children listened to low-pass filtered sentences and were asked to detect those that matched a target sentence. fMRI scanning revealed multiple regions of activation that predicted behavioral performance, independent of age-related changes in activation. Likewise, age-related changes in task activation were found that were independent of differences in task accuracy. The overall pattern of activation is interpreted in light of task demands and factors that may underlie age-related changes in task performance.     

Acquired aphasia with convulsive disorders in children: a case study with a seven-year follow-up.

In a 7-year follow-up a case of the “syndrome of acquired aphasia with convulsive disorder” is described. In particular, attention is paid to EEG patterns and linguistic analysis. Although seizures have been controlled medically and EEG abnormalities have tended to improve, no close parallel improvement has been observed in the patient's language disorders.     

Early processing of emotional faces in children with autism: An event-related potential study

Social deficits are one of the most striking manifestations of autism spectrum disorders (ASDs). Among these social deficits, the recognition and understanding of emotional facial expressions has been widely reported to be affected in ASDs. We investigated emotional face processing in children with and without autism using event-related potentials (ERPs). High-functioning children with autism (n = 15, mean age = 10.5 ± 3.3 years) completed an implicit emotional task while visual ERPs were recorded. Two groups of typically developing children (chronological age-matched and verbal equivalent age-matched [both ns = 15, mean age = 7.7 ± 3.8 years]) also participated in this study. The early ERP responses to faces (P1 and N170) were delayed, and the P1 was smaller in children with autism than in typically developing children of the same chronological age, revealing that the first stages of emotional face processing are affected in autism. However, when matched by verbal equivalent age, only P1 amplitude remained affected in autism. Our results suggest that the emotional and facial processing difficulties in autism could start from atypicalities in visual perceptual processes involving rapid feedback to primary visual areas and subsequent holistic processing.     

Selective attention in children with reading problems: A developmental study of incidental learning

The performance of poor readers and control children at three grade levels, first, third, and fifth grades, was compared on an incidental learning task adapted by Hagen (1967). A significant group by task interaction in a repeated measures ANOVA indicated that reading ability was differentially related to performance on the tasks. Relative to control children at all grade levels, poor readers obtained lower scores on the central task and higher scores on the incidental task. The absence of a grade × task × reading ability interaction indicated that selective attention follows the same developmental course in poor readers as in control children. The data suggest that the development of selective attention as reflected in performance on this task is delayed from 2 to 4 years in poor readers.We wish to thank the Sachem School District for permission to test the children, Mr. Morgan, reading specialist, and the teachers and children involved for their cooperation. We thank especially Mr. David Mello, principal of the Chippewa Elementary School for his invaluable assistance. We also thank Gordon Hale for providing the stimulus materials used in the study and for helpful suggestions regarding procedural details.     

Home-based family intervention for low-income children with asthma: a randomized controlled pilot study

Low-income African American children have disproportionately higher asthma morbidity and mortality. Education alone may not address barriers to asthma management due to psychosocial stress. This study evaluated the efficacy of a home-based family intervention integrating asthma education and strategies to address stress using a community-based participatory research model. Children age 8 to 13 with poorly controlled asthma and their caregivers were recruited from an urban hospital and an asthma camp. Caregivers with elevated scores on a stress measure were enrolled. Forty-three families were randomized to the 4- to 6-session Home Based Family Intervention (HBFI) or the single session of Enhanced Treatment as Usual (ETAU). All families received an asthma action plan and dust mite covers; children performed spirometry and demonstrated MDI/spacer technique at each home visit. The HBFI addressed family-selected goals targeting asthma management and stressors. Asthma management, morbidity, family functioning, and caregiver stress were assessed at baseline, postintervention, and 6 months after the intervention. ED visits and hospitalizations were ascertained by medical record review for a year after intervention completion. Only one child (5%) in HBFI had an asthma-related hospitalization compared to 7 patients (35%) in ETAU in the year following intervention. Participants in both groups demonstrated improved asthma management and family functioning, and reduced ED visits, symptom days, missed school days, and caregiver stress, but there were no differential treatment effects. The results suggest that a home-based intervention addressing medical and psychosocial needs may prevent hospitalizations for children with poorly controlled asthma and caregivers under stress.     

Working parents of children with behavioral problems: a study on the family-work interface

This study examines the process by which child behavioral problems are related to parents' well-being. We developed a family-work spillover model that was tested among 225 working parents. It was hypothesized that family-self conflict (FSC) mediates the relationship between child behavioral problems and parental strain, and that family-work conflict (FWC) mediates the relationship between parental strain and work engagement. Further, it was hypothesized that social support moderates the relationship between child behavioral problems and FSC. The results of (moderated) structural equation modeling supported the mediating role of FSC and FWC and the moderating role of social support. These findings suggest that the negative effects of raising a child with behavioral problems on parental well-being can be buffered by social support.
