The acquisition of skills by individuals with developmental disabilities typically includes the attainment of a certain mastery criterion. We conducted a survey of practitioners who indicated the most commonly used mastery criterion as 80% accuracy across three consecutive sessions. Based on these results, we conducted a series of three…

We replicated and extended the study by Koegel, Dunlap, and Dyer (1980) by examining the effects of 3 intertrial-interval (ITI) durations on skill acquisition in 2 children with autism spectrum disorders. Specifically, we compared the effect of short (2 s), progressive (2 s to 20 s), and long (20 s) ITIs on participants' mastery of tacts or…

We examined whether adults with dementia could learn to emit a picture-based communication response and if this skill would maintain over time. Three women with moderate to severe dementia were taught to exchange a picture card for a highly preferred activity. All participants quickly learned to exchange the picture card and maintained this…

We taught 5 adults with mild intellectual disabilities to respond appropriately to lures from strangers. Skills were taught in the classroom first and then in situ. Before training, participants did not walk away from confederate strangers who tried to lure them away. Participants demonstrated appropriate responses during classroom and in situ…

The preschool life skills (PLS) program (Hanley, Heal, Tiger, & Ingvarsson, 2007; Luczynski & Hanley, 2013) involves teaching social skills as a means of decreasing and preventing problem behavior. However, achieving durable outcomes as children transition across educational settings depend on the generalization and long-term maintenance…

Using a control group design, we evaluated the effectiveness of the "Stranger Safety" DVD (The Safe Side, 2004) and parent training of abduction-prevention skills with 6- to 8-year-old children. Children in the training or control group who did not demonstrate the safety skills received in situ training from their parents. There was no…

Cummings and Carr (2009) compared two methods of data collection in a behavioral intervention program for children with pervasive developmental disorders: collecting data on all trials versus only the first trial in a session. Results showed that basing a child's progress on first-trial data resulted in identifying mastery-level responding…

We evaluated the influence of two different frequencies of data collection on skill acquisition and maintenance within behavioral treatment programs for children with autism spectrum disorders. Six children were taught multiple skills in up to four different behavioral programs. Half of the skills were measured continuously (i.e., trial by trial),…

Five children with autism participated in learning sessions involving trials of an acquisition task interspersed with trials of three maintenance tasks. Correct responses to acquisition tasks were continuously reinforced throughout all conditions; reinforcement for competent performance of maintenance tasks differed systematically. All children…

Three autistic boys, aged 6-7, observed videotaped conversations consisting of 2 people discussing toys. Subsequent assessment of the boys using untrained topics of conversation, new stimuli, new persons, and other settings indicated that the children learned through video modeling, generalized their conversational skills, and maintained…

Three high school students with moderate mental retardation were taught to remove and discard broken materials (plates and glasses) safely from three locations. The multicomponent treatment package used was effective in teaching the skills, whereas follow-up data indicated mixed results. (Author/JDD)

Four young children were taught contact lens wear using a shaping procedure, which involved praise and tangibles for compliance and time-outs or restraint for noncompliance. At followup, levels of compliance were high for three children, while a subject with Down's syndrome showed low compliance with need for physical restraint throughout.…

Eleven mothers with developmental disabilities who provided neglectful child care received parent training. The training (consisting of verbal instructions, pictorial manuals, modeling, feedback, and reinforcement) resulted in rapid acquisition and maintenance of child-care skills in all mothers.

Results of a study with four autistic students (ages five-nine) showed that a picture training procedure was effective in teaching a generalized response to questions for which the relevant cue was visible, whereas specific generalization programing was required for situations in which the relevant cue was not visible.

Four children (ages 5-8) with tracheostomies were taught to self-administer a suctioning procedure via doll-centered simulations. Performance of all children improved as a function of training; skill maintenance was demonstrated during followup; and participants revealed high levels of satisfaction with outcomes. (Author/JDD)
