This study reports a revised version of the ‘Reading the Mind in the Voice’ (RMV) task. The original task (Rutherford et al., (2002), Journal of Autism and Developmental Disorders, 32, 189–194) suffered from ceiling effects and limited sensitivity. To improve that, the task was shortened and two more foils were added to each of the remaining items. About 50 adults with Asperger Syndrome (AS) or High Functioning Autism (HFA) and 22 matched controls took the revised task. Results show the revised task has good reliability and validity, is harder, and more sensitive in distinguishing the AS/HFA group from controls. Verbal IQ was positively correlated with performance, and females performed worse than males in the AS/HFA group. Results are discussed with regard to multi modal empathizing deficits in autism spectrum conditions (ASC).
