van der Meer, Larah; Kagohara, Debora; Achmadi, Donna; O'Reilly, Mark F.; Lancioni, Giulio E.; Sutherland, Dean; Sigafoos, Jeff – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
We compared speed of acquisition and preference for using a speech-generating device (SGD) versus manual signing (MS) as augmentative and alternative communication (AAC) options. Four children with developmental disabilities (DD), aged 5-10 years, were taught to request preferred objects using an iPod[R]-based SGD and MS. Intervention was…

van der Meer, Larah; Sigafoos, Jeff; O'Reilly, Mark F.; Lancioni, Giulio E. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
We synthesized studies that assessed preference for using different augmentative and alternative communication (AAC) options. Studies were identified via systematic searches of electronic databases, journals, and reference lists. Studies were evaluated in terms of: (a) participants, (b) setting, (c) communication options assessed, (d) design, (e)…

Choi, Hayoung; O'Reilly, Mark; Sigafoos, Jeff; Lancioni, Giulio – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
The purpose of this study was to evaluate the feasibility of teaching an integrated requesting-rejecting sequence. Four children with developmental disabilities were taught to request missing items and reject wrong items using either speech-generating devices (SGD) or picture-exchange (PE) communication. Data showed that the introduction of the…

Lancioni, Giulio E.; O'Reilly, Mark F.; Singh, Nirbhay N.; Sigafoos, Jeff; Didden, Robert; Oliva, Doretta; Campodonico, Francesca; de Pace, Claudia; Chiapparino, Claudia; Groeneweg, Jop – Research in Developmental Disabilities: A Multidisciplinary Journal, 2009
The first of these two studies assessed whether 11 participants with multiple disabilities of 5.3-18.2 (M = 10.7) years of age would succeed in combining a microswitch for accessing preferred environmental stimuli and a Voice Output Communication Aid (VOCA) for requesting social contact. The second study conducted a social validation assessment of…

Lancioni, Giulio E.; O'Reilly, Mark F.; Singh, Nirbhay N.; Sigafoos, Jeff; Oliva, Doretta; Severini, Laura – Research in Developmental Disabilities: A Multidisciplinary Journal, 2008
This study assessed the combination of two microswitches with a voice output communication aid (VOCA) with two persons (an adolescent and a young adult) with multiple disabilities. The microswitches allowed the participants to obtain direct access to preferred environmental stimuli; the VOCA enabled them to ask for caregiver's attention.…

Lancioni, Giulio E.; O'Reilly, Mark F.; Cuvo, Anthony J.; Singh, Nirbhay N.; Sigafoos, Jeff; Didden, Robert – Research in Developmental Disabilities: A Multidisciplinary Journal, 2007
This paper provides an overview of the literature dealing with the use of the Picture Exchange Communication System (PECS) and voice output communication aids (VOCAs) for promoting the performance of requests by students with developmental disabilities. Computerized and manual searches were carried out to identify the studies published during the…

Schlosser, Ralf W.; Sigafoos, Jeff – Research in Developmental Disabilities: A Multidisciplinary Journal, 2006
Augmentative and alternative communication (AAC) as an area of clinical and educational practice involves a myriad of decisions related to the symbols, devices, and strategies from which each client must choose. These decision-making points can be productively informed through evidence from comparative intervention studies. The purpose of this…

Sigafoos, Jeff; O'Reilly, Mark; Seely-York, Sue; Edrisinha, Chaturi – Research in Developmental Disabilities: A Multidisciplinary Journal, 2004
Students with autism and related developmental disabilities who do not speak are often taught to use some type of augmentative and alternative communication (AAC) system, such as a voice output communication aid (VOCA). One problem with such devices is that the person may be unable to communicate when the device is not readily accessible. We first…
