Increasing Verbal Behavior in a Young Adolescent Girl with Catatonia and Autism Spectrum Disorder.

Catatonia is a syndrome characterized as a cluster of difficulties in verbal and motor behavior that interferes with everyday function. This study analyzed the effects of a prompt-fading behavioral treatment package on the verbal behavior of an adolescent girl with autism and catatonia. Data were collected on three verbal responses previously observed in the participant's repertoire, including "Hi," "That sounds great," and "Excuse me." Instructors provided full manual guidance, in conjunction with a verbal model, when needed, to assist the participant in emitting the verbal responses. A functional relation was demonstrated between the prompt-fading package and the three verbal responses, and independent verbal responding emerged as manual prompts were faded. Responding was displayed across unfamiliar adults and maintained over time.

Script fading for children with autism: Generalization of social initiation skills from school to home.

We used a script-fading package to teach children with autism to initiate social interactions across various activities in the school setting, and we programmed for generalization in the untrained home setting with a sibling. The three participants, ages 8 to 10 years, demonstrated deficits in social initiations with their peers. During baseline, the participants emitted initiations to one another, although this behavior was variable and did not endure over time. With the introduction of the script-fading package, however, social initiations systematically increased. Moreover, the effects of the script-fading package generalized to the untrained home setting with a sibling. This study expands upon previous research by demonstrating the generalization of social initiations from school with peers to the home setting with siblings.

Acquisition and Generalization of Complex Empathetic Responses Among Children with Autism.

Empathy can be defined as a social interaction skill that consists of four components: (1) a statement voiced in the (2) appropriate intonation, accompanied by a (3) facial expression and (4) gesture that correspond to the affect of another individual. A multiple-baseline across response categories experimental design was used to evaluate the effectiveness of a prompt sequence (video modeling, in vivo modeling, manual and verbal prompting) and reinforcement to increase the frequency of complex empathetic responding by four children with autism. The number of complex empathetic responses increased systematically with the successive introduction of the treatment package. Additionally, generalization was demonstrated to untaught stimuli and a novel adult. Responding maintained over time to varying degrees for all participants. The data illustrate that children with autism can be taught using modeling, prompting, and reinforcement to discriminate between categories of affective stimuli and differentially respond with complex empathetic responses.

Graduated guidance delivered by parents to teach yoga to children with developmental delays.

We evaluated the effects of a parent-implemented intervention to teach yoga poses to 3 children with developmental delays. Graduated guidance, provided by the participants' mothers, was introduced in a multiple baseline design across the participants. With the introduction of intervention, imitation of the response chains increased over baseline for all participants. Generalization to novel and live models occurred for 2 participants. Results are discussed in terms of using behavior-analytic procedures to teach physical fitness activities to individuals with developmental disabilities.

Social Referencing and Children with Autism.

During social referencing, infants as young as 6 months of age look to others when confronted with unfamiliar or unexpected events in the environment and then respond to these events based on affective cues of the parent or caregiver (e.g., smiling and frowning). Social referencing is important for early communication and language development. Unfortunately, social referencing repertoires are limited or completely lacking in children with autism. Despite these documented social deficits, little research has focused on ameliorating social referencing deficits. The purpose of this paper is to present a behavior-analytic conceptualization of social referencing and the implications for ameliorating social referencing deficits of children with autism.

Teaching empathy skills to children with autism.

The purpose of this study was to teach empathetic responding to 4 children with autism. Instructors presented vignettes with dolls and puppets demonstrating various types of affect and used prompt delay, modeling, manual prompts, behavioral rehearsals, and reinforcement to teach participants to perform empathy responses. Increases in empathetic responding occurred systematically with the introduction of treatment across all participants and response categories. Furthermore, responding generalized from training to nontraining probe stimuli for all participants. Generalization occurred from dolls and puppets to actual people in a nontraining setting for 2 participants. Generalization was observed initially to the nontraining people and setting for the other participants, but responding subsequently decreased to baseline levels. Introduction of treatment in this setting produced rapid acquisition of target skills.

Establishing a generalized repertoire of helping behavior in children with autism.

The present study used a multiple baseline across participants design to assess whether 4 children with autism could learn a generalized repertoire of helping adults with different tasks through the use of a multicomponent teaching package. Different helping responses were taught in the presence of multiple exemplars of discriminative stimuli drawn from experimenter-defined categories of helping behavior (e.g., locating objects, putting away items, setting up an activity). During the training condition, video models, prompting, and reinforcement were used. The results showed that all 4 children learned to emit appropriate helping responses in the presence of discriminative stimuli from the helping categories used during training. Generalization of helping responses was observed in the presence of untrained discriminative stimuli during additional probe conditions. Additional pre- and postintervention generalization trials showed that the frequency of helping responses also increased in the presence of novel stimuli, in a novel setting, and with a novel instructor.

Generalized imitation of facial models by children with autism.

Imitation is an essential skill in the acquisition of language and communication skills. An initial phase in teaching young children with autism to engage in appropriate affective responding may be to teach the imitation of facial models. Using a multiple baseline across participants design, imitation training (consisting of modeling, prompting, differential reinforcement, and error correction) was introduced successively across 3 participants. Low and inconsistent rates of imitation of facial models were observed in baseline. All of the participants learned to imitate some of the facial models presented during imitation training, but only 2 of the 3 participants demonstrated generalized responding across stimuli.

Gross-motor skill acquisition by preschool dance students under self-instruction procedures.

The effects of two training procedures--(a) modeling and praise and (b) self-instruction, modeling, and praise--on complex gross-motor chain acquisition for preschool dance class students were evaluated. Six girls participated in the study. A multiple baseline design across six gross-motor chains with a secondary group comparison for treatment order effects was used. Both procedures were effective in teaching the gross-motor chains. Nevertheless, for 4 of the 6 participants, the self-instruction procedure produced a faster acquisition rate in at least two of the three comparable pairs of gross-motor chains. Furthermore, very early in gross-motor chain acquisition, for five of the six gross-motor chains, the self-instruction condition was associated with faster response acquisition.

Generalized imitation within three response classes in typically developing infants.

Effects of modeling and contingent praise on infant imitation of three different responses was analyzed. Generalization to nonreinforced probe models was assessed both within and across response types. Three 12- to 14-month-old infants and their mothers participated in this study. During baseline the mothers provided models only. During treatment mothers modeled and also praised contingent upon infant matching of the training models. During interspersed probe trials the mothers modeled different responses, which, if matched by the infant, produced no praise. The three responses modeled were motor-with-toy, motor-without-toy, and vocal responses. The dependent measure was the percentage of maternal models that were matched by the infant within 6 s. Nonmatching responses of the same response type were also measured. Results showed a systematic increase in the percentages of training and probe models matched by the three infants following the introduction of the model-and-praise treatment condition. Nonmatching responses did not systematically increase. Thus, imitation generalized within response class, but not across response classes.
