Abstract

Objective: Providing a detailed description of two participants who failed to acquire functional communication skills following a verbal modelling intervention and Picture Exchange Communication System (PECS) training.

Methods: Single-case research; Independent verbal requests, imitated verbal requests, word approximations and independent picture requests were assessed in a toddler and a pre-schooler with autism before and during two interventions.

Results: Although both participants used some vocalizations over the course of the study, experimental control was not demonstrated and the participants did not acquire a functional communication system prior to the cessation of intervention.

Conclusions: Future research should include additional, detailed reports that provide insight to why some children with autism do not respond to particular communication interventions and should investigate the pairing of particular child characteristics with targeted interventions.

Objetivo: Proveer una detalla descripción de dos participantes que no lograron desarrollar habilidades de comunicación funcionales después de una intervención de modelación verbal y entrenamiento en el Picture Exchange Communication System (PECS).

Métodos: Investigación de un solo caso; se valoraron solicitudes verbales independientes, solicitudes verbales por imitación, aproximaciones de palabras y solicitudes de imágenes independientes en un infante y en un pre-escolar con autismo antes y durante las dos intervenciones.

Resultados: Aunque ambos participantes utilizaron algunas vocalizaciones en el transcurso del estudio, no se demostró control experimental y los participantes no adquirieron un sistema de comunicación funcional antes de la cesación de la intervención.

Conclusiones: Nuevas investigaciones deben incluir reportes adicionales que proporcionen una visión detallada de por qué algunos niños con autismo no responden a intervenciones de comunicación específicas y deben de investigar la vinculación de las características del niño en particular con intervenciones específicas.

Palabras clave: trastornos del espectro autista, comunicación aumentativa y alternativa, intervenciones de comunicación, respuesta a la intervención
