Processing speed in children with clinical disorders

The Processing Speed Index (PSI) was first introduced on the Wechsler Intelligence Scale, Third Edition (WISC‐III; D. Wechsler, 1991), and little is known about its clinical significance. In a referred sample (N = 980), children with neurological disorders (ADHD, autism, bipolar disorder, and LD) had mean PSI and Freedom from Distractibility Index (FDI) scores that were below the group mean IQ and lower than Verbal Comprehension (VCI) and Perceptual Organization (POI). For these groups, Coding was lower than Symbol Search. The majority of these children had learning, attention, writing, and processing speed weaknesses. This pattern was not found in the other clinical groups. For children with depression, only PSI was low. Children with anxiety disorders, oppositional‐defiant disorder, and mental retardation had no PSI weakness. PSI and POI were both low in children with traumatic brain injury and spina bifida. Implications for a revision of the WISC‐III (WISC‐IV; D. Wechsler, 2003) are discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 333–343, 2005.     

The learning and study strategies of college students with ADHD

This study compared learning and study strategies of students with attention‐deficit/hyperactivity disorder (ADHD) to two groups: college students with learning disabilities (LD) and college students without disabilities. In addition, strengths and weaknesses within the ADHD group were examined on the Learning and Study Strategies Inventory, 2nd edition (LASSI; C.E. Weinstein & D.R. Palmer, 2002). The LASSI was also evaluated as a predictive measure for academic achievement for college students with ADHD compared to other students. Results indicate that several important differences may exist in the learning and study strategies of students with ADHD versus students with LD and students without disabilities. However, the LASSI may not be a useful tool for predicting academic achievement for college students with ADHD.

An intervention approach for children with teacher- and parent-identified attentional difficulties

Using a multimodal and multi-informant method for diagnosis, we selected 33 children by teacher and parent nomination for attention and work completion problems that met DSM-IV criteria for attention-deficit/hyperactivity disorder (ADHD). Of the 33 children in this group, 21 participated in the initial intervention, and 12 were placed in an ADHD control group and received the intervention after pre- and posttesting. A similarly selected group of 21 children without difficulties in attention and work completion served as a control group. Each child was assessed on pre- and posttest measures of visual and auditory attention. After an 18-week intervention period that included attention and problem-solving training, all children in the intervention and control groups were retested on visual and auditory tasks. Children in both ADHD groups showed significantly poorer initial performance on the visual attention task. Whereas the ADHD intervention group showed commensurate performance to the nondisabled control group after training, the ADHD control group did not show significant improvement over the same period. Auditory attention was poorer compared to the control group for both ADHD groups initially and improved only for the ADHD intervention group. These findings are discussed as a possible intervention for children with difficulties in strategy selection in a classroom setting.     

Evidence for unexpected weaknesses in learning in children with attention-deficit/hyperactivity disorder without reading disabilities

This study examined the mechanisms underlying verbal learning in children with and without attention-deficit/hyperactivity disorder (ADHD), none of whom had reading disabilities. Children with ADHD were compared to typically developing children on both process and product scores from the California Verbal Learning Test for Children. The findings indicated that children with ADHD initially learned the same number of words as controls but showed weaknesses recalling the words after delays, suggesting that children with ADHD are less efficient learners. Regardless of ADHD status, boys and girls performed differently. Boys used semantic clustering less frequently and recalled fewer words from the middle region of the list than girls; girls also outperformed boys in terms of overall performance, despite lower verbal IQ scores. These findings show that children with ADHD can exhibit unexpected weaknesses in learning even without a formal learning disability. Gender differences in verbal learning are also illustrated.     

Early literacy and parental writing mediation in young children with and without ADHD

The study compared early literacy of Israeli children aged five to six years with and without attention deficit hyperactivity disorder (ADHD), contrasted parental writing mediation in the two groups and tested the relations between parents’ mediation characteristics and children’s early literacy skills. Each of 62 parent‐child dyads (32 with ADHD) was videotaped at home while writing words. Videotapes were transcribed and analysed for mediation (specific writing task measures, emotional measures typical of problem‐solving tasks, and general measures of interactions). Children’s early literacy (word writing, letter knowledge and phonological awareness) was assessed at home. Results showed that children with ADHD already exhibited lower literacy achievements at ages five to six compared to their peers without ADHD. Parents of children with ADHD scored lower than parents of children without ADHD on the writing‐specific, emotional and general mediation measures. In both groups, the specific writing mediation measures correlated significantly with children’s early literacy. More emotional mediation measures correlated significantly with children’s early literacy in the ADHD than in the non‐ADHD group. Discussion focused on parent‐child writing interactions as a context of early literacy development among young children with ADHD.     

Patterns of performance on the Stroop Color and Word Test in children with learning,attentional, and psychiatric disabilities

The study presented here investigated the performance of children with learning, psychiatric, and attentional disabilities on the Stroop Color and Word Test. Forty‐three children diagnosed with a full battery of tests as learning disabled (LD [reading]) in grades K through 6 were matched on age, gender, ethnicity, and grade with 43 normal controls. They were also matched with groups of 43 children with psychiatric disorders and 43 children with attentional problems. All subjects were given the Stroop test, which took about 4 minutes per subject. The results indicated clear differences between the groups, with the LD and the psychiatric/attention deficit/hyperactivity disorder (ADHD) groups generating unique profiles different from the normal controls. The children with LD showed slower reading speed and less interference, while the subjects with ADHD and diagnoses showed impairment only on the Color‐Word score. A discriminant analysis using the three basic Stroop scales was able to significantly differentiate the LD group from the non–learning‐disabled (NLD) group (89%) and the LD group from a joint Psychiatric/ADHD group (86%). However, results were poorer for differentiating a joint LD/ADHD group from the NLD group (68%) and the LD from the ADHD group (59%). © 2002 Wiley Periodicals, Inc.     

Response Inhibition in Preschoolers at Familial Risk for Attention Deficit Hyperactivity Disorder: A Behavioral and Electrophysiological Stop‐Signal Study

Children participating in the Ben‐Gurion Infant Development Study were assessed with a dynamic‐tracking version of the stop‐signal task at the age of 5 years. The sample consisted of 60 males. Stop‐signal reaction time (SSRT) was correlated with concurrent ratings of the child's attention deficit hyperactivity disorder (ADHD) symptoms. Paternal symptoms measured in the child's early infancy predicted the child's performance in the stop‐signal task: Paternal inattentiveness predicted SSRT, whereas hyperactivity predicted error proportion. Maternal symptoms were not correlated with the performance of the child in the task. A subsample of children, who were tested while electrophysiological brain activity was measured, showed that having higher ADHD symptomatology, especially hyperactivity, correlated with less activity in the brain areas that are usually recruited by children for successful inhibition.     

Efficacy of an Intervention Program for Attention and Reflexivity in Children With Attention Deficit Hyperactivity Disorder

There has been increasing evidence in recent years of the need to adapt intervention programs to the specific needs of children with attention deficit hyperactivity disorder (ADHD). The main goal of this research work was to study the efficacy of an educational intervention program to improve attention and reflexivity in school children with ADHD in order to verify the improvements in symptoms associated with ADHD such as aggressivity, social isolation, anxiety, and attention deficit. The sample was comprised of 26 primary school children ranging from 7 to 10 years of age with ADHD. Symptoms of children with ADHD were evaluated by applying the Escalas Magallanes Screening Scale for Attention Deficits and Other Developmental Problems in Children (EMA‐DDA) at two time points (pre and post). The results show a statistically significant reduction in symptoms on the aggressivity and social isolation scales measured with the EMA‐DDA after applying the intervention program. These data supports the potential value of an intervention program for working with ADHD children.     

Evaluating the effectiveness of KooLKIDS: An interactive social emotional learning program for Australian primary school children

The effectiveness of universal social emotional learning (SEL) programs are dependent on the incorporation of best practice principles, including an evaluative component. In the present study, the effects of a best practice, teacher-led SEL program was examined with 854 children aged 8–12 years. KooLKIDS uses an interactive multimedia format and animated character to help children develop their emotion regulation capacities, social and friendship skills, empathy and compassion for others, and self-esteem. A quasi-experimental waitlist-control design was used to examine the impact of KooLKIDS on social and emotional competence, behavioral and emotional problems, academic achievement and effort. Hierarchical linear modeling demonstrated significant increases in social and emotional competence, and reductions in internalizing and externalizing problems in children post KooLKIDS program in the intervention group. The findings suggest that KooLKIDS has strong potential as a teacher-led, classroom-based, structured program for enhancing children's social and emotional learning.     

Sensitivity of Four Subtests of the Test of Everyday Attention for Children (TEA‐Ch) to Stimulant Medication in Children with ADHD

Children with attention deficit hyperactivity disorder (ADHD) were examined on four subtests of the Test of Everyday Attention for Children (TEA‐Ch) when on and off stimulant medication. Performance was assessed relative to 18 individually age‐matched controls. Children with ADHD performed significantly worse on TEA‐Ch measures when off compared to when on stimulant medication. This was found in both predominantly inattentive (n = 6) and combined inattentive and hyperactive‐impulsive (n = 12) subtypes. The age‐matched controls significantly improved with repeated testing on most TEA‐Ch measures. Significant differences were found between the unmedicated children with ADHD and age‐matched controls on sustained attention (Score! and Walk Don’t Walk) and attention control measures (Same and Opposite Worlds). When the ADHD group was on stimulant medication, with the exception of the Walk Don’t Walk subtest, no significant differences were found between them and the age‐matched controls. Unlike the TEA‐Ch subtests, the significant differences between the two groups on the Test of Word Reading Efficiency (TOWRE) subtests remained when attentional status was altered in the children with ADHD. The study supports further investigations of the TEA‐Ch as a measure sensitive to changes in stimulant medication in children with ADHD.     

Task performance and response to frustration in children with attention deficit hyperactivity disorder

The present study examined performance on an arithmetic task of increasing difficulty and a frustrating puzzle task for children with ADHD and comparison children. Emotional competence also was investigated in the two groups. Sixty‐four children, 21 previously diagnosed with ADHD, participated. Performance on the arithmetic task was measured in terms of completion and accuracy. Children with ADHD had similar rates of accuracy for all levels of difficulty, but completed fewer problems. Performance on the puzzle task was measured both through completion and persistence. Although children with ADHD persisted for a similar amount of time compared to children without ADHD, they were more likely to quit the task before completion. Children with ADHD also were more likely to report that they became frustrated with the task. Furthermore, they tended to report that in general, they become more frustrated than other children. With regard to emotional competence, children with ADHD did not differ from the comparison children on their reported understanding of their own emotions or attention to emotions; however, children with ADHD reported that they engage in less mood repair. © 2006 Wiley Periodicals, Inc.

The IQs of children with ADHD are normally distributed

The purpose of this investigation was to determine whether or not attention-deficit/hyperactivity disorder (ADHD)-when there was an absence of reading problems-was associated with having a high IQ. The vocabulary and block design short forms of the Wechsler Intelligence Scale for Children-Third Edition were administered to 63 children with ADHD, 69 children with reading difficulties (RD), and 68 children with comorbid ADHD + RD. Results indicated that the distributions of estimated Full Scale IQs (FSIQ) for each of the three groups of children did not differ significantly from a normal distribution, with the majority of children (more than 50%) in each group scoring in the average range. The percentage of children with ADHD who scored in the above-average range for FSIQ was not significantly higher than the percentages of children in the other two groups. No significant group differences emerged for estimated FSIQ, vocabulary, or block design. It was concluded that children with ADHD are no more likely to have an above-average IQ than are other children.     

Social-Emotional Learning Profiles of Preschoolers' Early School Success: A Person-Centered Approach

Examined how aspects of social-emotional learning (SEL)-specifically, emotion knowledge, emotional and social behaviors, social problem-solving, and self-regulation-clustered to typify groups of children who differ in terms of their motivation to learn, participation in the classroom, and other indices of early school adjustment and academic success. 275 four-year-old children from private day schools and Head Start were directly assessed and observed in these areas, and preschool and kindergarten teachers provided information on social and academic aspects of their school success. Three groups of children were identified: SEL Risk, SEL Competent-Social/Expressive, and SEL Competent-Restrained. Group members differed on demographic dimensions of gender and center type, and groups differed in meaningful ways on school success indices, pointing to needed prevention/intervention programming. In particular, the SEL Risk group could benefit from emotion-focused programming, and the long-term developmental trajectory of the SEL Competent-Restrained group requires study.     

Developmental co‐ordination disorder (DCD) in adolescents and adults in further and higher education

Few studies have looked at the strengths and weaknesses and needs of students with developmenal co‐ordination disorder (DCD). This paper describes a cohort of 93 UK students currently studying at further or higher education and who have reported motor difficulties present since childhood. The study group consisted of 21 reporting to have DCD only, 38 with DCD plus another diagnosis (a combination of any of the following: dyslexia, attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), learning difficulties); 23 subjects reporting dyslexia only, and 11 students who have not been formally diagnosed. The aim of this study was to first ascertain the similarities and differences between the students in the type of support received in childhood and while at university. The second goal was to examine the reported strengths and difficulties and see how they vary for each subgroup. The DCD group reported higher levels of motor‐related difficulties such as handwriting and also executive functioning difficulties. They also had higher levels of professional support given in childhood and were also more likely to be living at home with parents compared with the dyslexia group. Despite different types of difficulties reported in the DCD group, the range of student support given across all groups was similar. Significantly more of the dyslexia group were reported to be in receipt of disability student allowance than the DCD group. The DCD and other disorders group were seen to be an intermediary group in most of the areas studied.     

Student Diversity Representation and Reporting in Universal School-Based Social and Emotional Learning Programs: Implications for Generalizability

This paper addresses two major and potentially conflicting movements: the importance of diversity as both a conceptual and political issue and the rise of the evidence-based practice movement in education. This tension is particularly important when evaluating and reporting universal interventions because of their intended applicability across diverse groups of children and adolescents. This study contributes to this discussion through an analysis of published school-based universal social and emotional learning (SEL) intervention evaluations in terms of their theoretical and empirical attention to student diversity characteristics. We defined student diversity in terms of five characteristics: gender, race/ethnicity, SES, disability status, and sexual orientation/gender identity. We assessed how and when demographic characteristics were reported, how these characteristics were analyzed as moderators of program outcomes, and how differential effects based on diversity were incorporated into reported intervention generalizability discussions. Results showed that diversity characteristics were inconsistently reported across articles. Most studies did not test for moderating effects, but those that did found inconsistent effects across diversity characteristics. Further, conceptual and/or empirical support for conducting the moderation analyses was often not provided or sufficiently supported by previous literature or a hypothesis. This research highlights the need for a more nuanced understanding of how SEL program effects may be moderated by student demographic characteristics and suggests caution about the generalizability of the reviewed SEL programs across diverse groups of children and adolescents.     

A Tale of Two Cases: Lessons for Education From the Study of Two Boys Living With Half Their Brains

ABSTRACT— In recent years, educators have been looking increasingly to neuroscience to inform their understanding of how children’s brain and cognitive development are shaped by their learning experiences. However, while this new interdisciplinary approach presents an unprecedented opportunity to explore and debate the educational implications of neuropsychological research, a good model for this dialogue is lacking. This is in part because relatively little is known about the relationships between cognitive, emotional, and neurological development, in part because of a dearth of research methods designed to rigorously connect issues of learning and development to neuropsychological strengths and weaknesses, and in part because neuropsychological studies are rarely presented in a format that is conducive to meaningful cross‐disciplinary dialogue with educators. To begin to address these issues, in this article, I present the complementary cases of Nico and Brooke, two high‐functioning adolescents, who have suffered the removal of an entire brain hemisphere (Nico his right and Brooke his left) to control severe epilepsy. Through presenting a neuropsychological study of these rare boys’ emotion and affective prosody (vocal intonation) through the developmental lens of an educator, I reinterpret the neuropsychological findings for what they reveal about how the boys leveraged their emotional and cognitive strengths to learn important skills for which they were each missing half of the normally recruited neural hardware. While Nico’s and Brooke’s results seem on the surface to contradict expectations based on neuropsychological findings with adults, they combine to reveal a compensatory logic that begins to elucidate the active role of the learner as well as the organizing role of emotion in brain development, providing a jumping‐off point for discussion between educators and neuroscientists and a model for connecting neuropsychological strengths and weaknesses to learning.     

Improving expressive writing skills of children rated for ADHD symptoms

The present study examines the expressive writing abilities of children described by their teachers as having Attention Deficit Hyperactivity Disorder (ADHD) symptoms and of matched controls and the effects of two types of facilitation. A group of 35 ADHD children and matched controls are given the task of composing a letter either under standard instructions or with facilitation (a guide scheme), preceded by a brief training on how to use the facilitation. Results show that both groups drew benefit from the guide scheme. Despite the fact that differences between groups were maintained after the training for the case of spelling errors, the poorer performance of ADHD children vanished. It is concluded that ADHD children have poor expressive writing skills, but this can be improved through the help of a guide scheme preceded by brief training.     

A critical review of self‐regulated learning interventions for children with attention‐deficit hyperactivity disorder

School practitioners and educators are frequently challenged by the diverse and pervasive academic and behavioral needs of children at risk for and with attention‐deficit hyperactivity disorder (ADHD). This paper examines the outcome literature on self‐regulated learning (SRL) interventions for youth with ADHD by systematically reviewing the key intervention components and methodologies used. A total of 34 investigations, including 297 children and adolescents, were reviewed and coded on 34 variables across two dimensions (i.e., intervention components and methodology). In general, SRL interventions can be represented in terms of a three‐phase model of SRL that includes forethought, performance control, and self‐reflection processes. In this review, the vast majority of the published literature used single‐case design studies with a singular focus on the phase of performance control. Weaknesses of the existing literature include a lack of follow‐up data, attrition data, demographic information about teachers or other adult participants, and diversity in the sample. Strengths of the outcome literature are that a majority of the studies reported inclusion/exclusion criteria for samples, the criteria used to diagnose children as ADHD, and clinical significance for assessing treatment outcomes. Findings are discussed in relation to previous research, as well as directions for research and practice.     

Differences between WISC‐R and WISC‐III performance scale among children with ADHD

Reviews involving the Wechsler Scales for children suggest that Full Scale IQ scores on the Wechsler Intelligence Scale for Children, Third Edition, average 5 to 6 points lower than scores on the second edition of the scale [WISC‐R, Wechsler, D. (1974). Zimmerman & Woo‐Sam, 1997], with the differences distributed disproportionately over subtests, i.e., with larger discrepancies found within the Performance Scale (Wechsler, 1991). Changes on the revised subtests of the WISC‐III Performance Scale may place children with ADHD at a disadvantage compared to their performance on analogous WISC‐R subtests. We examined IQ test performance in 122 unmedicated children with ADHD (61 given the WISC‐R, 61 given the WISC‐III), and 46 children from a healthy, comparison group (23 given the WISC‐R, 23 given the WISC‐III). The ADHD and comparison group samples were matched for sex and for Verbal IQ between WISC‐R and WISC‐III. Children with ADHD had significantly lower Performance IQ on WISC‐III compared to the WISC‐R, with the Picture Arrangement subtest showing the most significant difference. In contrast, there were no significant differences between the WISC‐R and WISC‐III cohorts on Performance IQ or any Performance subtests among the comparison group. These findings highlight the importance of examining the comparability of ability test revisions among clinical and non‐clinical populations, and will be especially salient when the WISC‐III is revised. © 2003 Wiley Periodicals, Inc.

Teacher attributions for children's attention‐deficit/hyperactivity disorder behaviors predict experiences with children and with classroom behavioral management in a summer program practicum

Elementary school teachers often implement classroom behavioral management systems to address student misbehavior. Common problems targeted by these systems are the inattentive, hyperactive, and impulsive behaviors characteristic of attention‐deficit/hyperactivity disorder (ADHD). This study examined teachers' attributions for why children display ADHD behaviors, and how such attributions affect their experiences with children in the context of interventions to manage these behaviors. Participants were 32 preservice teachers undertaking a practicum in a summer program for 137 children (Grades 1–3), some of whom had ADHD. Teachers were trained to implement classroom‐wide behavioral management. Teachers' attributions for children's ADHD behaviors were assessed using a vignette measure, before teachers had met their students or begun training on intervention techniques. When controlling for attributions regarding oppositional behavior, teachers' initial attributions for ADHD behaviors as less internal/controllable predicted children reporting more positive relationships with that teacher during the summer program. Teachers' initial attributions for ADHD behaviors as less stable predicted teachers' greater satisfaction with the intervention techniques during the summer program and their greater attunement to children's social networks. Cognitions about the causes of children's ADHD behaviors held by preservice teachers may relate to their subsequent experiences with children in the context of implementing classroom behavioral management.
