The Cognitive Enhancement Therapy (CET) computerized therapy exercises are a subset of therapy programs from the Psychological Software Service's Neuropsychonline and PSSCogRehab cognitive rehabilitation therapy systems. This collection of therapy exercises was provided to Gerard Hogarty and Samuel Flesher for their research in the utilization of cognitive rehabilitation therapy techniques as part of treatment for schizophrenia.
