Durable,efficient, and economical electronic toilet-training devices for use with retarded children

Instrumented behavior observation and modification is typically an expensive process, yet the instruments used are often relatively simple and limited in function. Two sets of electronic devices were constructed to aid in training correct toileting behavior with retarded children. The body-worn alerting unit monitors the residents’ elimination as he moves through his environment. This set consists of a moisture detection circuit enclosed in a durable plastic box which is worn by the resident in either a harness or vest. The body-worn alerting unit is connected, via a cord, to underwear which have pliable wires running along their midline. The other set of units monitors elimination on a commode or toilet, and consists of a signaling box containing the moisture-detection circuit and a circular plate which is hung on the toilet or commode. Over 3 years of field testing have shown the units to be very durable and efficient.
