Abstract
Children with Turner Syndrome (TS) (n = 61) and healthy children (n = 60), whose ages ranged from 6 to 17, were compared on the focus-execute attention measures. The focus-execute component of attention is the ability to identify salient features, and perform rapid responses under conditions of distractions (Lyon, 1994). Findings suggested that children with TS performed significantly less well on the following measures of the focus-execute component of attention: Stroop Color and Word Test (Golden, 1978) and the Trail Making Test B (Reitan & Wolfson, 1985). No differences between the groups were found on the Symbol Digit Modalities Test (Smith, 1982) and Concentration Endurance Test (Brickenkamp, 1981). The pattern of performance on the focus-execute attention measures of young and old children with TS did not differ from that of young and old healthy comparison children. In general, children with TS performed within the normative range on low but not high task demands. Karyotype of children with TS was not related to the level of performance on the focus-execute attention measures. In examining unique contributions of several potentially confounding variables (e.g., visual-spatial, motor, impulse control, and working memory) to the focus-execute attention measures, visual-spatial skills and working memory were found to account for variance in the performance on the Stroop Color condition only, indicating that the focus-execute measures used in the study were relatively not confounded. Results are discussed in the context of an integrated model of attention proposed by the present author to explain the nature of the focus-execute component of attention in children with TS. The need for establishing ecological validity of the focus-execute attention measures to assist in planning psychoeducational interventions for children with TS is suggested.
