^*LISA's performances were compared to that of a 12-subject control group (C), matched for age (m = 27.25, SD = 2.67), gender, and education level (m = 17.25, SD = 1.36), by means of the analysis developed by Crawford and Howell (36) (CH) and Crawford and Garthwaite (44) using the computer program SINGLIMS.EXE. Not sufficient performances are in bold.
