The Development of Selective Attention in Children With Attention Deficit Hyperactivity Disorder

The influence of age on a selective attention task was studied in a sample of children with and without Attention Deficit Hyperactivity Disorder (ADHD). The impact of methylphenidate (MPH) treatment on selective attention was also investigated in the children with ADHD. Two age groups of children with ADHD and two age groups of control children were tested using a timed computer task. The task consisted of identifying visual target stimuli under various distracter conditions. Distracters varied on the basis of modality (i.e., visual, auditory, or both) and task relevance (i.e., meaningful or irrelevant). Reaction times and accuracy were measured. Children with ADHD were less efficient on the selective attention task than were children without ADHD, and older children were more efficient than younger children in both groups. Children without ADHD were influenced more by the nature of distracters than were children with ADHD. For children with ADHD, MPH improved performance overall.     

Comprehension of televised stories by preschool children with ADHD.

Investigated visual attention to and story comprehension of televised stories in 4- to 6-year-old children with attention deficit hyperactivity disorder (ADHD) and comparison children. Half of the children in each group watched the program with toys in the room, and the other half watched without toys. Visual attention to the television was recorded, and story comprehension was assessed by performance on cued recall questions. All children attended significantly less when toys were present, but the difference when toys were present was greater for children with ADHD. The groups did not differ on recall of factual information when toys were absent. When toys were present, the comparison children showed no decrement in performance on factual questions, whereas the performance of children with ADHD was significantly worse. On questions testing causal connections, the children with ADHD performed more poorly than comparison children regardless of whether toys were present. Implications of these results for understanding and treating the academic and social difficulties of children with ADHD are discussed.     

Developmental coordination disorder: associated problems in attention,learning, and psychosocial adjustment

This study investigated the problems of attention, learning and psychosocial adjustment evidenced by children with developmental coordination disorder (DCD). Forty-five children identified with DCD, 51 children identified as being suspect for DCD and 78 comparison children without motor problems on standardized tests of motor function participated in this study. Results revealed that both children with DCD and children suspect for DCD obtained significantly poorer scores on measures of attention and learning (reading, writing and spelling) than comparison children. Children with DCD and those suspect for DCD were also found to evidence a relatively high level of social problems and display a relatively high level of somatic complaints based on parent report. These findings indicate that all children with movement problems are at risk for problems in attention, learning and psychosocial adjustment. Assessment of children with movement problems, regardless of the degree or severity of these problems should examine a wide range of functions in addition to motor functioning. Such an approach, would assist in determining the types of intervention that would provide the most benefit to these children.     

Quantitative and qualitative evaluation of neuromotor behaviour in children with a specific speech and language disorder

Several studies have described problems in a wide area of motor functions in language impaired children. The purpose of this study was to identify the nature of the motor deficits in two subgroups of language impaired children. A standard neurological examination was performed on 18 children with an expressive language disorder and 21 children with a receptive language disorder. The motor performance of the language disordered children was compared with the motor performance of 23 normal children. The standard neurological examination allowed for a qualitative and quantitative assessment of five specific neurological subsystems. Handedness was determined for all children. The language impaired children had more motor problems than the control children on most neurological subsystems. There were few statistically significant differences between the two groups of language impaired children. An excess in left‐handedness was established in the group of children with a receptive language disorder. There was a co‐occurrence of verbal and non‐verbal deficits in language impaired children. As these motor problems put an additional burden on the development of language impaired children, they should be diagnosed as early as possible. Copyright © 2002 John Wiley & Sons, Ltd.     

Behavioral and personality characteristics of children with reactive attachment disorder

The authors compared behavioral and personality characteristics of children with reactive attachment disorder (RAD) with non-RAD children. Participants included parents of children with RAD (n = 21), parents of non-RAD children (n = 21), and some of the children (n = 20). The parents completed questionnaires regarding behavioral and personality characteristics of their children. Parents were also given the option of asking their children to participate in the study by completing self-report measures. Several significant findings were obtained. Children with RAD scored lower on empathy but higher on self-monitoring than non-RAD children. These differences were especially pronounced based on parent ratings and suggest that children with RAD may systematically report their personality traits in overly positive ways. Their scores also indicated considerably more behavioral problems than scores of the control children. Previous research has been generally qualitative in nature. The current research represents some of the first quantitative, empirical work documenting specific behaviors associated with the diagnosis of RAD. The findings of this study have implications for better understanding and dealing with reactive attachment disorder.

Predicting the Stability of Conduct Problems in Children with and Without Callous-Unemotional Traits

We tested predictors of persistence in conduct problems for children with and without callous-unemotional (CU) traits. Participants were 79 children of an original 98 children recruited from a community-wide screening to oversample children with conduct problems and to ensure equal numbers of children high and low on CU traits. The sample was reassessed at four yearly intervals and the 79 children (81%) were those with data at all four assessments. Children within each conduct problem group were divided into those with more and less stable patterns of conduct problems based on structured interviews with parent and child. Stability in conduct problems for children without CU traits was more strongly related to level of impulsivity and socioeconomic status, whereas children high on CU traits showed more stable conduct problems if they experienced higher rates of life stressors.     

“The Frog Ate the Bug and Made his Mouth Sad”: Narrative Competence in Children with Autism

This study compares the narrative abilities of 13 children with autism, 13 children with developmental delays, and 13 typically developing children matched on language ability. Although groups did not differ in their use of causal language or internal state terms, children with autism and children with developmental delays were less likely than typical children to identify the causes of characters' internal states. Rather, they tended simply to label emotions and explain actions. Children with autism and children with developmental delays also relied on a more restricted range of evaluative devices, which both convey point of view and maintain listener involvement. In addition, the narrative abilities of children with autism were linked to performance on measures of theory of mind and an index of conversational competence, whereas this was not the case among children with developmental delays. Findings are discussed in relation to the social, cognitive, and emotional underpinnings and consequences of narrative activity.     

Selective and sustained attention in children with spina bifida myelomeningocele

This study examined memory functioning in children and adolescents with 22q11.2 Deletion Syndrome (DS; velocardiofacial syndrome). An overall verbal better than nonverbal memory pattern was evident on the Test of Memory and Learning (TOMAL), with children with 22q11.2 DS performing significantly below their siblings and children with low average IQ but similar to children with autism on facial memory. Children with 22q11 DS also performed significantly below their siblings on tests of verbal working memory. Children with autism performed significantly poorer than the siblings of children with 22q11.2 DS only on their recall of stories. Delayed recall was significantly poorer in children with 22q11.2 DS and children with autism, compared to sibling controls. Although there were no significant group differences on tests of multiple trial verbal or visual learning, a relative weakness was noted with multiple trial visual learning in children with 22q11.2 DS and their siblings, suggesting that an alternative or interactive factor other than the deletion may account for the relatively better verbal compared to nonverbal memory abilities. Deficits in facial memory in children with both 22q11.2 DS and autism suggest disruptions in ventral temporal pathways such as between fusiform gyrus and parahippocampal/hippocampal regions whereas deficits in verbal working memory in children with 22q11.2 DS implicates dorsolateral prefrontal regions, both intimating aberrant white matter pathways.     

Physical growth delays and stress dysregulation in stunted and non-stunted Ukrainian institution-reared children

To study the effect of institutional rearing on physical growth and stress regulation we examined 16 institution-reared children (3–6 years old) in Ukraine and compared them with 18 native family-reared children pair-matched on age and gender. Physical growth trajectories were examined on the basis of archival medical records and current measurements of height, weight, and head circumference. Stress regulation was studied on the basis of diurnal salivary cortisol sampled six times during 1 day. 31% of institution-reared children were stunted at 48 months whereas none of the family-reared children were. Substantial delays in physical growth were observed in institution-reared children especially during the first year of life. From 24 months onwards a tendency for improvement in physical growth was evident among the temporarily stunted institution-reared children, with complete catch-up in weight and partial catch-up in height by the time of assessment. Chronically stunted institution-reared children demonstrated persistent severe growth delays. Institution-reared and family-reared children showed similar patterns of diurnal cortisol production with decreases over the day. However, temporarily stunted institution-reared children had a significantly higher total daily cortisol production than both chronically stunted institution-reared children and family-reared children. These data confirm previous findings regarding physical growth delays and stress dysregulation associated with institutional care, but also point to differences in cortisol production between stunted and non-stunted institution-reared children.     

Fear of storms and hurricanes in Antillean and Belgian children

The present study assessed fear of hurricanes in children who had been confronted with this natural event (i.e., Antillean children, n=161). Their fear levels were compared to those of children who are unfamiliar with such an event (i.e., Belgian children, n=185). Antillean children reported significantly higher levels of fear of storms than Belgian children did, thus providing support for the notion that exposure to dangerous events promotes children's fears of those events. Surprisingly, however, Antillean children had lower scores on the 'Hurricanes' item than Belgian children. Plausibly, differences in how children interpreted this item may have accounted for this unexpected finding. That is, ratings of Antillean children were probably based on actual experiences with hurricanes, whereas scores of Belgian children presumably reflected appraisal of threat in case they would be confronted with such an event. Implications of this finding for the assessment of childhood fears are briefly discussed.

Memory and learning in children with 22q11.2 deletion syndrome: evidence for ventral and dorsal stream disruption?

This study examined memory functioning in children and adolescents with 22q11.2 Deletion Syndrome (DS; velocardiofacial syndrome). An overall verbal better than nonverbal memory pattern was evident on the Test of Memory and Learning (TOMAL), with children with 22q11.2 DS performing significantly below their siblings and children with low average IQ but similar to children with autism on facial memory. Children with 22q11 DS also performed significantly below their siblings on tests of verbal working memory. Children with autism performed significantly poorer than the siblings of children with 22q11.2 DS only on their recall of stories. Delayed recall was significantly poorer in children with 22q11.2 DS and children with autism, compared to sibling controls. Although there were no significant group differences on tests of multiple trial verbal or visual learning, a relative weakness was noted with multiple trial visual learning in children with 22q11.2 DS and their siblings, suggesting that an alternative or interactive factor other than the deletion may account for the relatively better verbal compared to nonverbal memory abilities. Deficits in facial memory in children with both 22q11.2 DS and autism suggest disruptions in ventral temporal pathways such as between fusiform gyrus and parahippocampal/hippocampal regions whereas deficits in verbal working memory in children with 22q11.2 DS implicates dorsolateral prefrontal regions, both intimating aberrant white matter pathways.

An investigation of first‐order false belief understanding of children with congenital profound visual impairment

This study assessed theory of mind understanding in children with congenital profound visual impairment (CPVI): children who have had no access to visual information throughout development. Participants were 18 children with CPVI and no other impairments, aged between 5 and 11 years, and 18 children with normal vision, matched individually on chronological age, verbal IQ and verbal mental age. Three first‐order false belief tasks were presented twice each; the three tasks varied in the extent of deception and involvement of the child. Six of the children with CPVI failed one or more of the false belief tasks; all sighted children passed all of the tasks. The manipulations of deception and involvement did not influence the performance of the children with CPVI. Participant characteristics of the children with CPVI were examined in relation to their performance on the false belief tasks: chronological age and type of school attended were not found to be related to performance; verbal IQ and verbal mental age were found to differ in children with good and poor performance on the false belief tasks. The results are consistent with either a general pattern of delay in theory of mind development for children with CPVI, or with a subset of children who have longer‐term difficulties in this area.     

Threat-based cognitive biases in anxious children: comparison with non-anxious children before and after cognitive behavioural treatment

Attention and interpretation biases for threat stimuli were assessed in 19 anxious (ANX) children before and after cognitive behavioural therapy (CBT), and compared with responses from 19 non-anxious (NA) control children collected over the same period. Attentional bias was assessed using a picture version of the visual probe task with threat, neutral and pleasant pictures. Threat interpretation bias was assessed using both a homographs task in which children used homograph words in a sentence and their neutral or threatening meaning was assessed, and a stories task in which children rated their negative emotion, danger judgments, and influencing ability in ambiguous situations. ANX children showed attention biases towards threat on the visual probe task and threat interpretation biases on the stories task but not the homographs task at pre-treatment in comparison with NA children. Following treatment, ANX children's threat interpretation biases as assessed on the stories task reduced significantly to within levels comparable to NA children. However, ANX children continued to show larger attentional biases towards threat than pleasant pictures on the visual probe task at post-treatment, whereas NA children did not show attentional biases. Moreover, a residual threat interpretation style on the stories task at post-treatment was associated with higher anxiety symptoms in both ANX and NA children.     

Neurocognitive performance of 5- and 6-year-old children who met criteria for attention deficit/hyperactivity disorder at 18 months follow-up: results from a prospective population study

The aim of this prospective study was to examine whether neurocognitive performance of children aged 5–6 years distinguished children who were later diagnosed with attention deficit/hyperactivity disorder (ADHD) or borderline ADHD from children without ADHD after adjustment for behavioral measures and to examine the influence of comorbid psychopathology. Out of a general population of 1,317 children, 366 children were selected on the basis of their scores on the Child Behavior Checklist (CBCL). Eighteen months later, the parents were interviewed using a standardized child psychiatric interview: 33 children were classified as ADHD and 75 children as borderline ADHD, and there were 258 children without ADHD. Children with rated ADHD were significantly impaired on measures of visuomotor ability and working memory compared to children without ADHD after adjustment for CBCL results. The performance of borderline ADHD children was in between that of children with and without ADHD. In addition, 4 groups of children were analyzed: 9 ADHD, 24 ADHD with comorbid oppositional defiant disorder/conduct disorder (ODD/CD), 59 ODD/CD, and 274 controls. Children with rated comorbid ADHD and ODD/CD performed significantly worse on these tasks compared to children with rated ODD/CD and control children while they did not differ from ADHD children. Our results imply that neurocognitive measures can contribute to the early identification of ADHD with and without comorbid ODD/CD.     

Mindfulness Training for Parents and Their Children With ADHD Increases the Children’s Compliance

Children with ADHD are often non-compliant with parental instructions. Various methods have been used to reduce problem behaviors in these children, with medication and manipulation of behavioral contingencies being the most prevalent. An objection often raised by parents is that these management strategies require them to impose external control on the children which not only results in the children not learning self-control strategies, but also does not enhance positive interactions between them and their parents. Studies have shown that providing mindfulness training to parents, without a focus on reducing problem behaviors, can enhance positive interactions with their children and increase their satisfaction with parenting. We were interested to see what effects giving mindfulness training to two mothers, and subsequently to their children, would have on compliance by the children. Using a multiple baseline across mothers and children design, we found that giving a mother mindfulness training enhanced compliance by her child. When the children were subsequently given similar training, compliance increased even more markedly, and was maintained during follow-up. The mothers reported associated increases in satisfaction with the interactions with their children and happiness with parenting. We suspect that the mindfulness training produces personal transformations, both in parents and children, rather than teaching strategies for changing behavior.     

The abilities of children with mental retardation to remember personal experiences: implications for testimony

Investigated the abilities of children with mental retardation to remember the details of a personally experienced event. A simulated health check was administered to 20 children with mental retardation and 40 normally developing children, half matched on mental age (MA) and half matched on chronological age (CA) with the children with mental retardation. The children's memory was assessed immediately after the health check and 6 weeks later. Overall, the children with mental retardation accurately recalled the health check features, provided detail, and resisted misleading questions about features that did not occur. The group with mental retardation performed similarly to the MA matches on virtually all of the memory variables. The children with mental retardation performed worse than the CA matches on most of the memory variables, although they were able to recall a similar number of features. The findings are discussed in terms of the ability of children with mental retardation to provide accurate testimony.     

Independent effects of bilingualism and socioeconomic status on language ability and executive functioning

One hundred and seventy-five children who were 6-years old were assigned to one of four groups that differed in socioeconomic status (SES; working class or middle class) and language background (monolingual or bilingual). The children completed tests of nonverbal intelligence, language tests assessing receptive vocabulary and attention based on picture naming, and two tests of executive functioning. All children performed equivalently on the basic intelligence tests, but performance on the language and executive functioning tasks was influenced by both SES and bilingualism. Middle-class children outperformed working-class children on all measures, and bilingual children obtained lower scores than monolingual children on language tests but higher scores than monolingual children on the executive functioning tasks. There were no interactions with either group factors or task factors. Thus, each of SES and bilingualism contribute significantly and independently to children’s development irrespective of the child’s level on the other factor.
