Further observations of evoked potentials in obsessional patients.
This study was designed to replicate and extend earlier findings. Evoked potentials (EP) were recorded, using a task of varying complexity involving shape discrimination, with matched groups of obsessional and normal subjects. Results confirmed previous findings that obsessional patients are characterized by reduced amplitudes and decreased latencies of late EP components; divergences between the groups were more marked for tasks of increased complexity.
