A comparison was made between the verbal and spatial VESPAR scores for three matched groups of children, selected from the larger group on the basis of their CAT scores: a CAT-discrepant group was identified as having VCAT scores at least 15 points (1.5 SD) below their NVCAT scores; and two constructed CAT non-discrepant groups, one group individually matched for VCAT with the discrepant group and one individually matched for NVCAT with the discrepant group.
