Differential responsiveness by social stimuli was demonstrated in the communicative performance of an 8-year-old autistic boy. The pragmatic behavior of the subject varied with different communicative settings (waiting vs. interaction conditions) as well as with different communicative partners (mother, stranger, clinician). Communicative intentions, relational communication, topic strategies and differential responding to adults to communicative and non-communicative utterances were analyzed. Results indicated that the adults' communicative performance was a function of their relationships with the subject (mother, stranger, clinician) as well as the different experimental conditions (waiting, interacting). The child's communicative behavior showed greater consistency in conditions with the same interlocutor than over comparable experimental settings. Conclusions were drawn on how to facilitate communicative behavior and how to enhance generalization of remedial effects to the subject's natural environment.

Children with autism have difficulty in solving social problems and in generating multiple solutions to problems. They are, however, relatively skilled in responding to visual cues such as pictures and animations. Eight distinct social problems were presented on a computer, along with a choice of possible solutions, and an option to produce alternative solutions. Eight preschool children with autism and eight matched normal children went through 10 training sessions interleaved with 6 probe sessions. Children were asked to provide solutions to animated problem scenes in all the sessions. Unlike the probe sessions, in the training sessions problem solutions were first explained thoroughly by the trainer. Subsequently these explanations were illustrated using dynamic animations of the solutions. Although children with autism produced significantly fewer alternative solutions compared to their normal peers, a steady increase across probe sessions was observed for the autistic group. The frequency of new ideas was directly predicted by the diagnostic category of autism. Results suggest young children with autism and their normal peers can be taught problem-solving strategies with the aid of computer interfaces. More research is required to establish whether such computer-assisted instruction will generalize to nontrained problem situations in real-life contexts.

a b s t r a c t This experiment compared the effect of computerized visual feedback (computer assisted instruction) with traditional play interaction (personal instruction) in promoting vocal imitation in children with autism. Ten non-verbal children with autism participated in ten sessions. Each session was composed of four sections: a parent and a trainer interacted with the child on the computer or using play interactions. The study was conducted as a simultaneous treatment design and the sequence of experimental conditions was randomized across sessions. Participants showed significantly greater vocal imitations in the computer assisted instruction condition, compared with the personal instruction condition. This trend was present in nine out of ten children. Vocal imitations increased across the sessions, with greater increments in the computer assisted instruction condition. These effects were consistent across both parent and trainer.a d d r e s s Correspondence should be addressed to: d r v e r a b e r n a r do p i t z,

This study compared the effect of structured play (SP) and facilitated play (FP) in promoting spontaneity and responsiveness in communication and play behaviors in children with autism. SP is characterized by the use of mass practice trials under the instruction of the experimenter while FP incorporated incidental teaching with multiple exemplars. Eight preschoolers participated in a crossover design of both play conditions. Gains in appropriate communication and play were observed across both treatments. Respondent communicative acts occurred more frequently across all participants during SP compared with FP. The preliminary results indicate an interaction between the mental age of the child and the teaching paradigm used. The need to match treatment goals and specific methods of the play intervention to the skill profile of participants is discussed.

This research examined whether children with autism could be trained to improve their conversational skills and whether this led to changes in standard tests of theory of mind (ToM). Three high-functioning children with autism participated in a multiple baseline across participants design. The children were taught how to initiate a conversation, take turns during conversation, listen attentively, maintain a conversation topic, and change a conversation topic appropriately. The children were tested for ToM using False Belief tasks before and after training sessions. Results indicate that the amount of shared interest exhibited by the children with autism during conversation with their caregivers increased during training sessions. The children also made more responses that were appropriate to the context of the conversation. Performance on the False Belief tasks remained constant throughout the study. Results are discussed with respect to the implications of results of performance in standard ToM tasks.
