Objective: The current study examined the impact of the gender of children with ADHD on teachers' perceptions toward inattentive, hyperactive, or oppositional behaviors, and how these perceptions relate to teachers' ratings of children's impairment and referral recommendations. Method: Teachers read eight vignettes depicting boys and girls with…

Background: Children with attention deficit hyperactivity disorder (ADHD) and with autism spectrum disorders (ASD) are known to have cognitive control deficits. Some studies suggest that such deficits may be reduced when motivation is increased through tangible reinforcers. Whether these deficits can also be modulated by non-tangible reinforcers…

This study investigated (1) hyperactive children's performance on an adaptation of the operant vigilance task, and (2) possible differences in performance when short intersignal intervals versus long intervals were employed. (Author/DB)

The attention controls of 30 learning disabled and 30 normal males (8-to 11-years-old) were tested by a vigilance task in which vigilance was defined as ability to detect infrequently occurring signals over a prolonged time period when signals were embedded in a background of regularly occurring events.

This study extends previous research by examining whether maternal inattention, impulsivity, and hyperactivity are associated with different parenting behaviors. Ninety-six mother-son dyads participated in the study, and the boys ranged between 4 and 8 years of age. Maternal inattention was uniquely and positively associated with mothers' use of…

Examined the differential validity of teacher ratings of Inattention/Overactivity and Aggression among 48 clinic-referred boys. These ratings were correlated with observations undertaken in three different classroom settings. Results indicated that the teachers were able to differentiate significantly between these externalizing behaviors in the…

Sustained attention to visual and auditory stimuli and reflection-impulsivity were examined in 48 hyperactive and 48 normal 9 and 14 year old boys. Multivariate analyses, followed by univariate tests, indicated that the nonhyperactive Ss increased sustained attention efficiency with age to both visual and auditory Stimuli. Hyperactive Ss increased…

A modified operant design demonstrated the effectiveness of the feedback procedure. Significant changes were evidenced by all groups of subjects. Initial results and follow-up observations indicated that the attending behavior of the experimental subjects increased and was maintained, without the use of tangible reinforcers. (Author)

The behavior ratings and psychometric profiles of children with attention deficit disorders (ADD) and children with developmental reading disorders (DRD) were compared. DRD children were more impaired in academic attainment and showed evidence of qualitative disturbances in reading and spelling. ADD children showed no qualitative reading or…

Thirteen hyperactive males (ages five through eight) were rated on activity prior to, during, and after a period of ascending music stimuli. It was hypothesized that they would become less active during, rather than before or after, the stimulus. Activity significantly increased during the music program, thus rejecting the hypothesis. (Author/SJL)

Defined peer-rated, narrow-band dimensions of undercontrolled behavior of 362 third through sixth grade boys that was associated with peer rejection. Results revealed three narrow-band dimensions in the peer perceptions of grade school boys: (1) aggression; (2) hyperactivity; and (3) inattention-immaturity. (SH)

WISC performance of 77 boys with serious school learning problems was analyzed according to three factors hypothesized to reflect functional differences in learning styles. Sub-samples identified as Learning Disordered, Learning Disordered-Hyperactive, or Educable Mentally Retarded, differed in patterns of subtest scores, although within groups…

Thirty-four stimulant-treated, academically deficient, and attention deficit disordered, hyperactive (ADDH) boys (ages 7-12) participated in a 16-week, intensive cognitive training program focusing on academic skills and tasks. Intervention did not enhance self-esteem and there was poor agreement between teacher ratings of academic competence and…

Hyperactivity, impulsivity, and inattention are among the most common behaviour problems in children. The aim of this study was to estimate the prevalence of hyperactivity-impulsivity and inattention in the Canadian population of 2-11-year-old girls and boys, using data from the first National Longitudinal Survey of Children and Youth (NLSCY)…
