Performance of disturbed hyperactive and nonhyperactive children on an objective measure of hyperactivity

Twenty hyperactive emotionally disturbed children (6–11 years) and a matched sample of nonhyperactive emotionally disturbed children were selected from the population of a therapeutic day treatment facility on the basis of teacher ratings. They were administered the Matching Familiar Figures Test-20 and were rated on several scales of impulsivity and/or hyperactivity. Each subject was required to perform on the Delay Task of the Gordon Diagnostic System, which required them to inhibit behavioral responding on a temporally based schedule (DRL-6) in order to win points. Children classified as hyperactive, whether by one or more criteria, were relatively unable to refrain from emitting a high number of nonreinforced responses. Moreover, these performance differences persisted regardless of age or IQ and were stable over the 8 minutes required to complete the test.The authors gratefully acknowledge the efforts of the following members of the Institute of Clinical Psychology, University of Virginia: Richard Abidin, Ann Loper, Ronald Reeve, and Sherry Kraft.

Stimulus-seeking behavior in hyperactive and nonhyperactive children

Auditory and visual stimulus-seeking behavior was measured in hyperactive and nonhyperactive youngsters. The design controlled for motor activity level. The results indicate that hyperactive children preferred auditory stimulation more than the control children. There were no differences in stimulus-seeking preferences in the visual modality. The groups did not differ in motor activity. It was concluded that abnormally high needs for stimulation are important in hyperactivity.The authors would like to express their appreciation to James Fogarty, Superintendent, Walter Galvin, Principal, and the many teachers, students, and parents of the Greene Avenue Learning Center of BOCES II in Sayville, New York for their cooperation and support in this study.

Self-control behavior in hyperactive and nonhyperactive children

This study was aimed at evaluating the self-control behaviors of hyperactive (HA) and nonhyperactive (NHA) first-grade pupils under conditions of repeated failure on a previously learned concept formation task. Subjects were divided into HA and NHA groups on the basis of their scores on the Conners (1969) Teacher Rating Scale. During the training stage of the experiment the children learned a concept formation task under a schedule of contingent positive reinforcement. In the test stage they performed the same task but under a negative noncontingent reinforcement schedule. The results revealed no differences in initial rate of learning the task between the groups. After the introduction of the negative noncontingent reinforcement schedule, however, the HA group showed a marked decrease in the use of effective problem-solving strategies. The HA children's performance on the concept formation task was accompanied by the emission of negative self-evaluations and solution-irrelevant statements. The NHA group used significantly more statements showing useful goal directed cognitive mediations than the HA children. The results suggested that HA children may have deficits in self-control skills.Grateful acknowledgment is made to the two anonymous reviewers whose insightful comments were very helpful in producing the final form of this paper.     

Attention and distractibility during reading in hyperactive boys

Nonhyperactive and clinically defined hyperactive boys were administered reading tasks under quiet and distracting conditions. Hyperactive boys were less attentive to task relevant stimuli and more attentive to task irrelevant stimuli than their controls. Our results demonstrate that the previous findings of inattentiveness among hyperactive boys on laboratory tasks can be generalized to more typical school activities such as reading.     

The assessment of impulsivity and mediating behaviors in hyperactive and nonhyperactive boys

Twenty boys (6–8 years) rated by their teachers as hyperactive and a matched sample of nonhyperactive boys performed a task that required them to withhold responding for a set time interval in order to be rewarded (DRL 6-second schedule). Half of each group worked on a one-button console while the other half was provided with additional collateral buttons. Results indicated that hyperactive children were relatively unable to perform efficiently on the task, and that this deficit endured regardless of age, IQ, or experimental condition. DRL was thus found to discriminate accurately between teacher-rated and parent-rated hyperactive and nonhyperactive children. Furthermore, a wide variety of self-generated mediating behaviors was observed, and it was determined that a child's DRL performance was related to the kind of mediating behaviors he displayed. Results are discussed in terms of the clinical assessment of hyperactivity and the training of impulsive children.This report is based upon a dissertation submitted by the author in partial fulfillment for the Ph.D. degree.

Types of private speech produced by hyperactive and nonhyperactive boys

Types and amount of private speech (audible talking that is not addressed to another person) were assessed during the free play of 16 hyperactive and 16 nonhyperactive boys. Verbalizations were coded into nine categories that denoted the boys' level of use of verbal control of their own behavior (Luria, 1961; Kohlberg, Yeager, & Hjertholm; 1968). Differences in amount and type of private speech between hyperactive and nonhyperactive boys were found to indicate that hyperactive boys may be presenting a specific or general cognitive lag in development. Treatment ramifications are discussed.     

A comparison of two objective measures of sexual arousal of women

The efficacy of two objective measures of sexual arousal of women was compared by simultaneously recording vaginal blood volume by means of a photoplethysmograph and labial temperature by means of a thermistor-clip during and after stimulation by an erotic film. Both measures increased during the stimulation, and they were highly correlated with each other in six of the eight subjects, indicating that both were valid measures of sexual arousal. During the stimulation, labial temperature was significantly correlated with subjective ratings of arousal while vaginal blood volume only approached significance. During the 15-min period following stimulation, the measures neither correlated significantly with subjective ratings nor each other, and both had a tendency not to return to prestimulation levels.     

A comparison of behavioral and attentional functioning in children diagnosed as hyperactive or learning-disabled

The attentional and behavioral functioning of children diagnosed as hyperactive (ADHD), learning-disabled (LD), and hyperactive/learning-disabled were compared, using standardized behavior rating scales across raters and settings, and results from a battery of standardized neuropsychological tests. The ADHD and LD groups were "pure" samples with respect to comorbidity. Multiple discriminant-function analyses on the behavioral and neuropsychological data showed that one variate made clear-cut discriminations among and between each of the three groups. The constructs self-regulation, task accuracy/planning/speed, and aggression differentiated the three groups, while sustained attention did not. The results lend strong support to the validity of ADHD as a diagnostic entity apart from LD, and suggest that poor self-regulation and inhibition of behavior may be the hallmark of ADHD.     

A comparison of objective classroom measures and teacher ratings of attention deficit disorder

Children identified as Attention Deficit Disorder (ADD) on the basis of teacher ratings using the SNAP Rating Scale were compared to non- ADD children on objective classroom measures including observations of classroom behavior, examination of the organization of children's desks, and scoring of daily academic work. Analyses provided some support for the ability of the objective measures to differentiate between teacheridentified ADD and non-ADD children, though there was considerable overlap on the distributions of most variables between groups. Six measures chosen by a discriminant analysis combined to predict teacher ratings in 83% of the cases. The inclusion of academic, observational, and desk measures in the discriminant function indicates the importance of a multivariate assessment of this construct.Portions of this paper were presented as part of a symposium, W. Pelham (Chair),Identification and diagnosis of children with attention deficit disorder/hyperactivity, at the meeting of the American Psychological Association, Washington, D.C., August 1982.

Effect of noise distractibility on the spans of apprehension of hyperactive boys

Denton and McIntyre (1978), using a forced-choice letterrecognition procedure, demonstrated increasing reductions in the spans of apprehension of hyperactive as compared to normal boys when a signal letter was embedded within an increasing number of noise letters. In the present study, the effect of variations in the amount of physical signal-noise similarity and noise redundancy upon the spans of apprehension of hyperactive and normal boys was compared to determine whether noise letters act as more potent distractors for the hyperactive boys. Results indicated the spans of both groups were effected equivalently by variations in signal-noise similarity and noise redundancy. No evidence for a distractibility explanation was obtained.     

An analysis of the hyperactive syndrome: A comparison of hyperactive,behavior problem,asthmatic, and normal children

In an attempt to determine whether the commonly described deficits associated with hyperactivity — inappropriate activity, short attention span, low frustration tolerance, and impulsivity — are unique to this population, hyperactive, behavior problem, asthmatic, and normal control children were studied. The tests most often used in research with hyperactives were administered. Hyperactives, when compared to normals, did show deficits in the aforementioned areas. However, when compared to the behavior problem and asthmatic children only the attentional deficits clearly differentiated hyperactives from the other children.This research was supported, in part, by grants from the Ontario Ministry of Health (DM-304) and the Ontario Mental Health Foundation (#652-76A).     

Intratask distractibility in hyperkinetic and nonhyperkinetic children

Previous laboratory studies that have either introduced extraneous environmental stimulation or tested children in cubicles have failed to provide support for the common clinical notion that hyperkinetic children are highly distractible. Based on the Rosenthal and Allen (1978) proposal, distractibility was investigated by introducing irrelevant information within the task context. Intratask distractibility was examined by comparing the performance of hyperkinetic and nonhyperkinetic children on a speeded classification task. Errors were measured for responses to slides containing either zero, constant, one varying, or two varying irrelevant stimulus dimensions. Dimensional salience of the three dimensions used in the study was measured for each child. The data indicate that hyperkinetics made more errors than nonhyperkinetics when constant irrelevant or two varying irrelevant dimensions were presented, but the two groups made equal errors when there was no irrelevant information presented within the stimulus array. No group differences in distractibility were found when the irrelevant dimension was low salience. It was concluded that salience of distractors presented within the task context may be useful in specifying the particular task conditions in which hyperkinetic children exhibit high distractibility. This study is based on the first author's Ph.D. thesis in the Department of Psychology, Vanderbilt University, Nashville, Tennessee.

Production deficiencies in free recall: A comparison of hyperactive,learning-disabled,and normal children

Free recall of weakly categorizable words was compared in hyperactive (ADDH), reading-disabled, and normal boys. During a baseline trial, hyperactive boys recalled fewer words and showed less category organization than both reading-disabled and normal boys. Following a manipulation designed to encourage semantic encoding of words, hyperactive boys showed an immediate improvement in item recall and organization so that their free-recall performance was similar to that of reading-disabled and normal children. During later trials of a multiple-trial format, hyperactive boys recalled fewer words than did the reading-disabled and normal boys, despite maintaining equality in category organization. Rather than lacking the skill to use semantic organization as a strategy in free recall, hyperactive boys had difficulty in spontaneously generating the organizational strategy in response to instructions to remember and sustaining sufficient effort to task completion.     

Social-cognitive processing and depressive symptoms in children: A comparison of measures

We assessed aspects of the reliability and validity of three measures of socialcognitive processing in children that have been developed to investigate the relations of such processes to childhood depression: the Children's Attributional Style Questionnaire (CASQ), the Children's Negative Cognitive Error Questionnaire (CNCEQ), and the Common Beliefs Inventory for Students (CBIS). In an unselected sample of 61 children, aged 8 to 12, the internal consistencies of the total scores on the CNCEQ and the CBIS were good; for the CASQ, it was only moderate. Internal consistencies of all subscale scores were inadequate. Despite this, several subscale and total scores were significantly associated with depressive symptoms, and the measures were generally correlated with each other. Although these data are encouraging concerning the role of social-cognitive processing in childhood depression, the field needs to develop psychometrically stronger measures and to test the role of social cognition in prospective studies of depression.This study was supported in part by a grant from the Spencer Foundation Awards to Young Scholars Program to the first author. The authors would like to express their thanks to Deborah Long for secretarial assistance, and to W. Edward Craighead, John Curry, and two anonymous reviewers for comments on an earlier draft of this article.     

Attaining and maintaining preparation: A comparison of attention in hyperactive,normal, and disturbed control children

The hypothesis that hyperactive children have a deficit in sustained attention was investigated. Eighteen children who had attention deficit disorder with hyperactivity (ADDH), aged 7 to 11 years, were compared with children who had conduct disorder (n = 15), mixed conduct disorder and ADDH (n = 26), emotional disorder (n = 18), or learning disability (n = 22), and with normal controls (n = 15). The subjects were tested on three versions of the Continuous Performance Task. Sustained attention was assessed from performance with increasing time on task and from ability to prepare attention in response to a warning. Performance of all subjects deteriorated with increasing time and improved with the opportunity to prepare attention. Hyperactive subjects were not more adversely affected by increasing time, nor did they benefit less than controls from the opportunity to prepare attention. Data reanalysis after rediagnosis according to ICD-9 criteria did not change the results. This study did not confirm the hypothesis that hyperactive children have a unique sustained attention deficit.     

Schedule-induced behavior in hyperactive children

A schedule-induced behavior paradigm was used to investigate the activity patterns of hyperactive children in a standardized situation. In Experiment I, 10 hyperactive and 10 normal control children matched for age, sex, and IQ were observed under conditions of baseline and schedule. Measures of a number of categorized activities were taken on a time-sampling basis. Hyperactive children were more active than controls in baseline and did not respond to the schedule, unlike the controls who became significantly more active in schedule conditions. In Experiment II, 12 hyperactive and 6 normal children were again subjected to the same experimental paradigm, but in two of the four experimental sessions the stimulant drug methylphenidate was administered in an attempt to reduce the amount of baseline activity. Results were substantially similar to those of Experiment I, with hyperactive children more active than controls in baseline and insensitive to the schedule. There was no overall effect of drug administration on the behavior of either group. There were some ratedependent effects of both drug and schedule conditions.     

Laterality and selective attention in hyperactive children

Laterality and selective attention were investigated in a group of 20 hyperactive children and their matched controls using a dichotic listening task. There was a strong rightear advantage for both groups indicating that hyperactive children were not different from normal children in hemispheric specialization for verbal stimuli. In the selective attention experiment hyperactive children were again not different from normal children in their ability either to select the input designated as relevant or to resist the distraction of input designated irrelevant. Both groups gave more correct responses from the right ear than from the left ear, and more intrusions from the right ear than from the left. The results do not suggest abnormalities of lateralization for verbal material or indicate the existence of a selective attentional deficit. It is suggested that such reported deftcits may be situation or taskspecific.
