The effects of massed versus distributed learning have been well studied in the verbal and motor learning literature, with findings suggesting enhanced outcomes from distributing learning over time. However, some studies have found limited evidence to support enhanced outcomes from distributed learning when applied to an entire academic course.…

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…

Many children who require hospitalization in the pediatric intensive care unit (ICU) are unable to or have difficulty communicating through speech, whether because of preexisting or acute conditions. Children who are unable to be heard and understood using only speech benefit from aided augmentative and alternative communication (AAC), including…

Although the last decade has welcomed evidence that individuals with Rett syndrome (RTT) can communicate using alternative and augmentative communication (AAC), less is known about effective procedures for teaching various component skills required for expressive communication of individuals with complex communication needs. The purpose of the…

Individuals with complex communication needs cannot articulate what they want to communicate through intelligible speech. Consequently, augmentative and alternative communication (AAC) methods can be taught to these individuals so they can communicate in a way that is understood by others. As part of the training on how to use AAC methods,…

The purpose of this study was to select a core vocabulary list obtained from Mandarin Chinese-speaking Taiwanese persons without disabilities. Mandarin Chinese is dominant and official language of Taiwan. A total of 28 participants, equally divided among seven age groups, were recruited for the study. In all, 112 samples across different…

Little is known about what features of AAC systems are regarded by AAC professionals as more suitable for children with different characteristics. A survey was conducted in which participants rated the suitability of hypothetical AAC systems on a Likert scale from 1 ("very unsuitable") to 7 ("very suitable") alongside a…

Workplace accommodations can reduce barriers to employment for people who use augmentative and alternative communication (AAC), however, the lack of accommodations continues to challenge participation in employment. This systematic review identified and analyzed barriers and facilitators to implementing workplace accommodations for adults (19…

The purpose of this large-scale descriptive study was to investigate the impact of an implementation model designed to provide U.S. classroom teachers with the knowledge, skills, and resources required to provide aided augmentative and alternative communication (AAC) instruction to their students with extensive support needs and complex…

Background: The communicative effectiveness of persons with aphasia (PWA) has been assessed through a range of functional communication measures. However, variability in interpretations of what is covered by the term "functional communication" may have resulted in challenges to the implementation of appropriate and consistent…

The American Speech-Language-Hearing Association (n.d.) suggests that acquisition and use of augmentative and alternative communication (AAC) is dynamic and that learning multiple modalities may be beneficial particularly for those individuals with severe disabilities. Evaluation of response variability after training multiple modalities has yet…

Purpose: Previous research has shown that many speech-language pathologists (SLPs) lack confidence in conducting augmentative and alternative communication (AAC) evaluations. The AAC Clinical Assessment Project team developed a protocol to help guide SLPs to complete AAC assessments for children with autism spectrum disorder (ASD). This article…
