Long-term follow-up of echolalia and question answering.
A long-term follow-up of echolalia and correct question answering was conducted for 6 subjects from three previously published studies. The follow-up periods ranged from 26 to 57 months. In a training site follow-up, subjects were exposed to baseline/posttraining conditions in which the original trainer and/or a novel person(s) presented trained and untrained questions. Four subjects displayed echolalia below baseline levels, and another did so in some assessments. Overall, echolalia was lower than in baseline in 80.6% of the follow-ups. Five subjects displayed correct responding above baseline levels. No clear differences were noted in correct responding or echolalia between the trainer and novel-person presentations or between trained and untrained questions. In a follow-up in a natural environment conducted by a novel person, lower than baseline levels of echolalia were displayed by 3 subjects; 2 subjects displayed lower than baseline levels in some assessments. Two subjects consistently displayed correct responding above baseline, and 3 did so occasionally. Issues related to the study of maintenance are discussed.
