Intervention Condition

The effects of the systematic use of mands (non-yes/no questions and instructions to verbalize), models (imitative prompts), and specific consequent events on the productive verbal behavior of three unresponsive, socially isolate, language-delayed preschool children were investigated in a multiple-baseline design within a classroom free play period. Following a lengthy intervention condition, experimental procedures were systematically faded out to check for maintenance effects. The treatment resulted in increases in total verbalizations and nonobligatory speech (initiations) by the subjects. Subjects also became more responsive in obligatory speech situations. In a second free play (generalization) setting, increased rates of total child verbalizations and nonobligatory verbalizations were observed for all three subjects, and two of the three subjects were more responsive compared to their baselines in the first free play setting. Rate of total teacher verbalizations and questions were also higher in this setting. Maintenance of the treatment effects was shown during the fading condition in the intervention setting. The subjects' MLUs (mean length of utterance) increased during the intervention condition when the teacher began prompting a minimum of two-word utterances in response to a mand or model.

Comprehension Intervention

This study was designed to investigate the effects of script-based and nonscript-based treatment on the language comprehension of 4 preschool children with mental retardation. An alternating treatments design (ATD) in combination with a multiple baseline design was used to evaluate treatment effects. Treatments were comprised of three script routines and three nonscript activities. Two semantic constructions were selected for training and counterbalanced across subjects and treatments. Daily probes were administered to assess the effects of the treatments. The script-based treatment was more effective than the nonscript treatment in facilitating comprehension of the targeted semantic constructions in 3 of the 4 subjects.

Enhanced Milieu Teaching

The primary and generalized effects of Enhanced Milieu Teaching were examined with six preschool children with significant language delays. In a multiple baseline design across children, trainers implemented the naturalistic language intervention during play-based interaction sessions in the children's preschool classrooms. Children systematically increased their use of targeted language skills during the intervention sessions, and these changes were maintained when the treatment was discontinued. Generalized changes in children's communication resulting from the intervention were examined with untrained teachers, peers, and parents. Some generalization to untrained partners was observed for all children. Correlational analyses indicated that greater numbers of child utterances and greater diversity in vocabulary were associated with increased talking and mands for verbalization presented by partners.

Letter Sound

The effects of training in letter-sound correspondences and phonemic decoding (segmenting and blending skills) on three kindergartners' word recognition abilities were examined using a single-subject multiple-baseline design across behaviors and subjects. Whereas CVC pseudowords were trained, generalization to untrained CVC pseudowords, untrained CVC real words, untrained CV and VC pseudowords, and untrained CV and VC real words were assessed. Generalization occurred to all of the untrained constructions for two of the three subjects. The third subject did not show the same degree of generalization to VC pseudowords and real words; however, after three training sessions, this subject read all VC constructions with 100% accuracy. Findings are consistent with group training studies that have shown the benefits of decoding training on word recognition and spelling skills and with studies that have demonstrated the effects of generalization to less complex structures when more complex structures are trained.

Initial Intervention

A peer-mediated intervention designed to promote communicative interaction by 3 handicapped children with behavioral, social, and communicative deficits in an integrated preschool was evaluated. All 6 normally developing preschoolers in the class were taught facilitative strategies. A multiple baseline design across subjects was used in combination with withdrawal designs for 2 of the subjects. Significant increases in communicative interaction occurred when the peers were prompted to use the strategies with the 3 handicapped classmates. In particular, increases in the handicapped children's response rates were demonstrated during free play observations. In addition, fewer initiations by the handicapped children during the peer intervention was shown to be attributable to reductions in teacher prompting. Generalization to other settings was demonstrated by 1 subject. Although most strategy use by peers was prompted during the initial intervention phases, prompting dropped gradually while peer strategy use was maintained by the end of the study. Results of this study have implications for refining our ability to tailor interventions individually to improve treatment effectiveness based upon the characteristics of handicapped children.

The purpose of this study was to determine the suitability of using interactive videodisc for developing community based simulations for students with moderate disabilities. A multiple baseline design across students was used to assess the effects of the training package, that made use of an interactive videodisc-based simulation, on the students' skills to locate and purchase an item in simulated and natural convenience store settings. Three adolescents with moderate disabilities were taught how to access the equipment, discriminate items, and shop for snack items in a convenience store. During baseline and intervention phases, purchasing skills were assessed daily in simulated settings and weekly in natural settings. Measures included the number of extra actions to locate an item, percentage of assistance from the teacher, and number of purchasing steps completed correctly. All students learned how to access the equipment, to discriminate visuals of shopping items, and to interact in the simulated store setting. In addition for the simulated settings, students demonstrated a decrease in the number of extra actions needed to locate an item and an increase in the number of purchasing steps performed correctly.

Baseline Design

This study evaluated a program to develop help-recruiting competencies as a strategy to facilitate the transition of adjudicated male youths with disabilities residing in a segregated institution. six adjudicated male youths with disabilities participated in the study. a multiple baseline design across behaviors was used to evaluate the youths' acquisition of help-recruiting skills. self-reported measures of the actions taken by the youths in the process of pursuing transition goals were also collected. youths' performance in role-play situations and generalization probes indicated consistent improvements in help-recruiting skills following training. the youths established a total of 17 transition goals at the beginning of the study, of which 11 were attained as planned, 4 were still in progress at the end of data collection, and 2 were dropped. participants also increased the size of their social support network and reported improved satisfaction with their social competencies. the limitations and benefits of developing help-recruiting competencies to facilitate attainment of transition goals among at-risk youths with disabilities are discussed.
