Consistent, unemotional use of timeout, without ancillary punishers, is shown to result in typical extinction curves (rather than the steeper gradient of punishment curves) for both autistic and mentally impaired children with widely different abrasive behaviors. Dangers of punishment and the therapeutic value of reduced environmental stimulation…

The study evaluated a commonly used component of brief time-out, in which release from time-out is delayed contingent on the occurrence of the disruption. Data were collected for one normal and two mentally retarded children on time-out producing behaviors and delay-producing behaviors during time-out. (Author/CL)

Two papers describe studies to decrease inappropriate social behaviors of severely retarded students. R. Spangler and others in "The Effect of a Time-Out Procedure on the Duration of Tantrum Behavior in a 13-Year-Old Severely Retarded Male S" report on a three phase study in which a combination of verbal instructions and a timeout procedure…

Timeout from auditory reinforcement was employed to reduce rates of target responses of two mentally retarded children (9 and 11 years old). Results supported the response deceleration characteristic of timeout from auditory reinforcement and indicated its effectiveness as a response reduction technique. (Author)

The present study developed a timeout procedure that did not require removal of the misbehaver from the learning environment and applied the procedure to the disruptive behaviors of five severely retarded children (8 to 18 years old). (Author/SBH)

Psychological treatment techniques for the control of self-injury in a 13-year-old male with de Lange syndrome (a rare disorder characterized by retarded mental and physical development) are presented. Techniques, which included mild punishment, time out, and differential reinforcement, produced a clinically significant control of self-injurious…
