“…For a number of years, one of the present authors (Higson) conducted a token economy programme with long-stay patients in a psychiatric hospital (Higson, Woods, Tannahill, & EHis, 1985;Woods, Higson, & Tannahill, 1984). Detailed analysis showed that verbal control was an integral part of this program, for example, staff provided (a) verbal prompts to initiate target behavior, (b) verbal statements, ac co mpanying token presentation, of whether or not the subject's performance of the target behavior matched the specified criteria, (c) verbal descriptions of the contingencies in operation and instructions given to subjects at group meetings, especially when a subject was new to the program, (d) brief written verbal descriptions of the contingencies posted throughout the ward (e.g., "make your bed and earn six tokens"), and (e) a full written description of the contingencies upon each new subject's introduction to the ward.…”
