  • WISC-III indicate Wechlser Intelligence Scales for Children-III; WLPB-R, Woodcock Language Proficiency Battery–Revised; BASC, Behavioral Assessment System for Children; CVLTC, California Verbal Learning Test for Children; CPT, Conners' Continuous Performance Test; NESS, Neurological Examination for Soft Signs.

  • * Higher scores are optimal for the variables Full-Scale IQ, Attention/Executive Functions, Reading, Adaptive Skills, List A Memory, List A Learning Slope, and Hit Reaction Time. Lower scores are optimal for Externalizing Problems, School Problems, d Prime, and Sequential Movements Time.
