Concept maps make students' knowledge visible. Creating a mind map gives students an opportunity to organize their knowledge and allows instructors to visualize and assess it. When students create mind maps at multiple time points, instructors can compare the maps and use the themes, patterns, and gaps that emerge to reflect on their teaching and…

Background: This study explores communication partners' perceptions of their roles and responsibilities in the design, planning and use of augmentative and alternative communication (AAC) with individuals with severe/profound intellectual disability. Methods: A qualitative descriptive approach was used. Purposive sampling, data collection and…

Multiple contemporary theories emphasize the quantity and quality of child vocalizations for promoting spoken language acquisition. Yet, empirical evidence for facilitating vocal development is strikingly lacking including for children with autism spectrum disorder (ASD) who have difficulty developing language. We evaluate use of contingent…

The current study examined vocalizations that occurred during training of the Picture Exchange Communication System for three U.S. preschool-age participants with autism spectrum disorder. In Phase IV, the protocol incorporates a delay to reinforcement in an effort to encourage vocalizations; however, the manual does not suggest additional…

This simulation study assessed the ability of Speech-Output Technologies (SOTs) to keep in-time during conversational repair. Fifty-eight Other Initiated Repair (OIR) initiators were collected from transcripts of repair interaction sequences collected from past research. A range of selection latencies were then used to calculate simulated…

The present study investigated the relationship between lexicon and grammar in individuals who use graphic symbol-based aided augmentative and alternative communication (AAC). Data came from 60 transcripts of generalization sessions that were part of two previous intervention studies, aimed at improving the expressive vocabulary and grammar of 12…

Literacy skills can assist in the navigation and enjoyment of adult life. For individuals who have reached adulthood without strong literacy skills, opportunities for continued literacy learning are few. Redesigning AAC technologies to support literacy skill development could extend literacy learning opportunities for adults with developmental…

Students with complex communication needs have increasingly been using non-dedicated communication systems, such as mobile devices, to support their communication needs. This in turn, has led to an increased used of augmentative and alternative communication apps. The main challenge currently faced is the lack of empirically validated apps and…

It is estimated that approximately 97 million people in the world have complex communication needs and may benefit from alternative and augmentative communication (AAC). Although AAC is considered an evidenced-based intervention, device abandonment remains common, and researchers have attempted to analyze the causes of people abandoning devices.…

Background: Those supporting children and young people who use augmentative and alternative communication (AAC) contribute to ongoing complex decision-making about communication aid selection and support. Little is known about how these decisions are made in practice and how attributes of the communication aid are described or considered. Aims: To…

A group of U.S. school speech-language pathologists (SLPs; N = 233), via survey, provided the following business-as-usual (BAU) augmentative and alternative communication (AAC) practices: (a) service delivery models, (b) treatment intensity, (c) the number of aided models provided, and (d) caseload size and knowledge. In addition to descriptive…

Core vocabulary lists and vocabulary inventories vary according to language. Lists from one language cannot and should not be assumed to be translatable, as words represent language-specific concepts and grammar. In this manuscript, we (a) present the results of a vocabulary overlap analysis between different published core vocabulary lists in…

Background: People who have communication difficulties may benefit from using augmentative and alternative communication (AAC). Understanding and measuring outcomes from the use of AAC is an important part of evaluating the impact of devices and services. Outcome measurement needs to reflect the changing nature of the impact of using AAC on an…

Despite advances in the field of augmentative and alternative communication (AAC), outcomes among children who require AAC remain discouraging. Practitioners may benefit from guidelines to aid decision-making in relation to supporting pre-linguistic communicators. We conducted an open-ended questionnaire of 30 AAC professionals from six…

Although augmentative and alternative communication (AAC) strategies are often used by autistic youth, little is known about the use of AAC in inpatient psychiatric settings. This study evaluated how demographic and clinical factors (e.g., language level, IQ) related to AAC use in a well-characterized sample of 527 autistic youth (78.7% male, mean…
