For children with autism or intellectual and developmental disabilities who also have complex communication needs, communication is a necessary skill set to increase independence and quality of life. Understanding the how, where, and communication style being taught is important for identifying deficits in the field as well as which interventions…

Augmentative and Alternative Communication systems (AAC) are used to support communication abilities of children with severe communication impairments; as a result, teachers should be prepared to teach in their classrooms those students who use AAC. The purpose of this paper is to provide an overview of AAC, in terms of what teachers need to know…

This study compared a picture exchange (PE) system and an iPad®-based speech generating device (SGD) when teaching requesting skills to preschoolers with developmental disabilities and limited functional speech. A multiple baseline design with counterbalancing the order of two instruction conditions across participants was applied to compare the…

The purpose of this study was to investigate the effects of Transition to Literacy (T2L) software features (i.e., dynamic text and speech output upon selection of a graphic symbol) within a grid display in an augmentative and alternative communication (AAC) app on the single-word reading skills of five individuals with severe disabilities and…

This article provides clinicians and educators a useful conceptualization of general instructional strategies often used to promote the performance of requests in children with developmental disabilities, and which can be applied in interventions that utilize augmentative and alternative communication. A case study illustrates the specialized…

Many individuals with autism cannot speak or cannot speak intelligibly. A variety of aided augmentative and alternative communication (AAC) approaches have been investigated. Most of the research on these approaches has been single-case research, with small numbers of participants. The purpose of this investigation was to meta-analyze the single…

This article describes comprehensive, high-quality writing instruction for students with developmental disabilities. The Enriched Writers' Workshop combines differentiated writing process instruction with social communication instruction and cognitive strategy instruction for students with complex writing needs across a wide range of ages. It…

This study compares use of the Picture Exchange Communication System (PECS) and a Voice Output Communication Aide (VOCA) with four preschool children who were either non-speaking or limited in their ability to speak and did not use an AAC system to communicate functionally. An alternating treatment single subject design was used to measure…

Research-based information is used to support the idea of the use of adaptations and accommodations for early childhood students who have varying disabilities. Multiple adaptations and accommodations are outlined. A step-by-step plan is provided on how to make specific adaptations and accommodations to fit the specific needs of early childhood…

Visual-language and augmentative-communication systems for individuals with pervasive developmental disorders and autism are presented as both legitimate languages and as effective strategies. Methods for choosing target environments, generating appropriate vocabulary, creating interactive language boards, and implementing them with appropriate…

The controversy regarding the use of facilitated communication with individuals having developmental disabilities is addressed, and an oversight procedure for the use of this methodology is recommended, which includes informed consent from all involved, the inclusion of a validation protocol, and the inclusion of other potential means of…

Educational and behavioural psychologists have made major contributions to the field of communication intervention for individuals with developmental and physical disabilities. A brief personal perspective is provided on some of the major works and contributors that have shaped the field over the past 25 years. Major contributions and personal…

This text explains the phenomenon of facilitated communication (FC) from an empirical, data-based, and/or clinical perspective. It is not a how-to-facilitate text, but one that explores the clinical and sociological reality of FC. A common theme running through each of the papers in the book is the question of FC's legitimacy. The papers reveal…

This thesis investigated the effects of adding the learning of American Sign Language (ASL) signs (as part of the Applied Behavior Analysis) on the negative behaviors of seven developmentally disabled children (aged 8-13 years). The children were measured on the following: overall disruptive behavior; aggressive behavior; tantrums; and the use of…

Potential individual variations in the effectiveness of facilitated communication (FC) were examined with 20 students with autism and related disorders. Use of multiple methods (including auditory or visual input, simple point responses, and typing) provided no clear support for validity of FC over students' independent communication. Increased…
