The objective is to examine underlying associations between childhood fears, behavior problems and neurobehavioral functioning (NBF) in school-age children. Healthy, regular school children (N = 135), from second, fourth and sixth grade classes were assessed. Data regarding children's fears and behavioral problems were obtained with the Revised Fear Survey Schedule for Children, the Child Behavior Checklist, and NBF was assessed using a computerized neurobehavioral evaluation system. Significant correlations between childhood fears and NBF measures and somatic complaints were found. Children who reported higher levels of fears demonstrated lower working memory span (r = 0.24, p less than 0.05), lower motor speed (r = -0.23, p less than 0.05), and had more somatic complaints (r = 0.20, p less than 0.05). Furthermore, younger children reported less fears than older ones and girls reported more fears than boys. These results highlight significant association between childhood fears, NBF and behavior problems in a non-clinical group children. Lower working memory span is an important component of executive control that may be an underlying factor in fears and anxiety in children.
