Effects of experimenter and mother presence on the attentional performance and activity of hyperactive boys.

The attentional performance, activity, and off-task behavior of hyperactive boys with and without conduct problems and normal boys were compared on a cancellation task under three conditions: when performing the task alone, with mother present, and with experimenter present. Results indicated that both the hyperactive groups achieved poorer attentional scores than normal subjects in the alone and mother present conditions, but improved in the experimenter present condition. The performance of the hyperactive boys with conduct problems was particularly affected by this condition. The activity and off-task behavior scores of both the hyperactive groups were higher than controls in all conditions, although the hyperactive boys with conduct problems decreased in off-task behavior when the experimenter was present. Attention and behavior scores were not significantly correlated. The implications of these findings for assessment of hyperactivity, and the role of noncompliance in the attentional behavior of hyperactive children, are discussed.

Mother-child interactions and noncompliance in hyperactive boys with and without conduct problems.

Mother-child interaction, and parent ratings of child noncompliance and defiance among hyperactive boys with conduct problems (H/CP), hyperactive boys without conduct problems (H), and normal boys (N) were compared. Results indicated more negative mother-child interactions and more noncompliance in the H/CP group than in the other two groups. The H group was more noncompliant than normal children, but these groups showed no differences in defiance, nor in the behaviour of mothers. The implications of these findings in relation to the development of conduct problems in hyperactive children, treatment and research are discussed.

The development of Australian normative data for infant temperament.

Utilizing the revised Infant Temperament Questionnaire previously validated for use with Australian populations, a cohort of 2443 infants aged 4-8 months was studied. This sample was recruited in such a manner as to be representative of all infants of this age group in the State of Victoria. Temperament values obtained differed significantly from American norms on four of the nine temperament dimensions, providing further evidence for the importance of using culturally appropriate norms. There were associations between temperament and problem behaviours and some parent characteristics. The normative values for temperament presented are recommended for use in Australian settings.

Classification of hyperactive children.

Numerical taxonomy was used in an attempt to identify subgroups in a sample of children labelled as hyperactive. In each of two analyses of Conners' questionnaire data (supplied by parents and by teachers), two classes were obtained, apparently differentiated on the basis of rated severity of behavioural symptoms. No aetiologically important differentiating attributes emerged. There was poor agreement between the two data sources. particularly in the classification of the more disordered group; and, over all, teachers perceived the children as less deviant than did parents. Comparison with earlier studies indicated the similarity in behavioural symptoms between this sample and those from other countries. However, the obtained data argued against the existence of a pure hyperactive disorder, since there was virtually no differentiation between conduct problems and items relating more specifically to hyperactivity. Hyperactivity as a diagnostic category appears to have little meaning either aetiologically, or descriptively, or prescriptively.
