Improving social interaction in chronic psychotic using discriminated avoidance ("nagging"): experimental analysis and generalization.

Fichter et al. (1976) · Journal of applied behavior analysis 1976
★ The Verdict

A quick verbal prompt delivered right when voice volume drops can make audible speech stick, even after adults with chronic psychosis leave the hospital.

01Research in Context

01

What this study did

Researchers worked with one adult who had lived in a psychiatric hospital for years. The man rarely spoke above a whisper and kept his arms folded.

Staff gave a quick verbal cue (“speak up” or “uncross your arms”) any time his voice dropped too low or his arms stayed folded. This cue acted like a brief “nag” that he could avoid by performing the social action.

The team tracked voice volume, speech length, and arm position across three hospital settings. They used a multiple-baseline design to be sure the prompts, not something else, caused any change.

02

What they found

Voice volume and how long he talked rose right after the prompts began. These gains held when staff faded the cues.

After discharge, the man spoke loudly enough to order food in a diner and chat with a neighbor. Arm crossing improved in the hospital but dropped back to baseline once he left.

The study showed that simple, timely prompts can boost some social skills in adults with chronic psychosis, but not every skill travels to new places.

03

How this fits with other research

Ferguson et al. (2021) extended this idea to autistic adults with intellectual disability. Instead of adult nagging, peers gave brief cues during group behavioral skills training. Social gains appeared just as fast, showing the prompt source can change without losing power.

Conant et al. (1984) conceptually replicated the effect with autistic children. Typical classmates delivered the prompts, again proving that peer-delivered cues can replace adult nagging while keeping the same multiple-baseline design.

Yamamoto et al. (2022) pushed the idea further by using performance feedback alone—no nagging at all—to teach workplace niceties to autistic teens. Together, these studies form a 45-year arc: from hospital nagging to peer cues to feedback-only, each keeping the quick, clear contingency that drives social change.

04

Why it matters

You don’t need fancy equipment to help withdrawn adults speak up. A calm, immediate “speak louder” can be enough.

If you work in a day program or group home, try giving one concise prompt the moment voice volume drops. Track it for a week.

Pair the prompt with natural rewards—staff attention, task choice, or a smile—to keep the skill alive after you fade the cue.

03Original abstract

Three social-interaction behaviors of a withdrawn chronic schizophrenic were increased using a discriminated avoidance ("nagging") procedure. The three behaviors were: (a) voice volume loud enough so that two-thirds of his speech was intellibible at a distance of 3m; (b) duration of speech of at least 15 sec; (c) placement of hands and elbows on the armrests of the chair in which he was sitting. "Nagging" consisted of verbal prompts to improve performance when the behaviors did not meet their criteria. A combined withdrawal and multiple-baseline design was used to evaluate the effectiveness of the procedure, and the contingency was sequentially applied to each of the three behaviors in each of four different interactions to determine the degree of stimulus and response generalization. Results indicated that the contingency was the effective element in increasing the patient's appropriate performance, and that there was a high degree of stimulus generalization and a moderate degree of response generalization. After the patient's discharge from the hospital, the durability of improvement across time and setting was determined in followup sessions conducted at a day treatment center and at a residential care home. Volume and duration generalized well to the new settings, while arm placement extinguished immediately.
