In an initial factor-analytic study using preschool children (41 girls, 44 boys), the errors and latencies on the Matching Familiar Figures Test saturated different factors. A second study (47 boys, ...39 girls), employing the Kansas Reflection Impulsivity Scale for Preschoolers, replicated this finding. In addition, the error (but not the latency) was associated with measures of gross-motor, fine-motor, and perceptual-motor coordination. The results suggest that error measures a maturational dimension of task-oriented attention for this age group.
Artificial neural networks (ANNs) are a type of artificial intelligence software inspired by biological neuronal systems that can be used for nonlinear statistical modeling. In recent years, these ...applications have played an increasing role in predictive and classification modeling in medical research. We review the basic concepts behind ANNs and examine the role of this technology in selected applications in prostate cancer research.
Factor analysis of a revised Behavior Problem Checklist for a sample of preschool children yielded six oblique primary factors and two orthogonal second-order factors. Scores on these factors were ...correlated with activity level, gross- and fine-motor incoordination, minor physical anomalies, and sociability. There were sex differences and factor differences in the resulting patterns of correlations. The patterns of correlations also indicated that the six primary factors could be collapsed into two broad (Conduct and Personality) and two narrow (Distractibility and Attention Seeking) factors.

The present research reports correlations between ratings of distractibility and minor physical anomalies and gross motor incoordination. For an original and two replication samples of preschool ...children, there were significant average weighted correlations between distractibility and both minor physical anomalies and gross motor incoordination for boys. Also, the magnitude of the correlation between distractibility and the congenital characteristics was significantly higher for boys. Although neither parental rejection nor parental restrictiveness was related to boys' distractibility, parental rejection was marginally related to girls' distractibility.
Children diagnosed Conduct Disorder, Attention Deficit Disorder, or Anxiety Disorder by DSM-III criteria were compared to contrast groups of Physically Disabled and Normal children using the Conners ...Teacher Rating Scale (CTRS). Discriminant function analyses of the CTRS ratings yielded accurate classification (67% correct) only when Conduct was combined with Attention Deficit and Normals were combined with Physically Disabled. The teacher raters seemed to be describing the children as behaviorally disordered with and without hyperactivity. The data also suggest that Attention Deficit Disorder is part of a broader Conduct Problems dimension.
