Deficits in communicating one's wants and needs can have significant and detrimental effects on quality of life. Particularly for individuals with autism spectrum disorder (ASD) and other related disabilities, manding is a pivotal skill that influences long-term prognosis. Mand training is complex and relies on several components to facilitate…

This study aimed to evaluate the impact of a speech-generating device (SGD) application on manding skills in Chinese children with autism spectrum disorder (ASD). Given the communication challenges faced by many individuals with ASD, alternative methods for expressing needs are crucial. The SGD utilized speech synthesis technology to provide…

For children with developmental or language delays, mand interventions have been identified as an integral part of educational programming (e.g., Greer & Ross, 2008; Shafer, 1994; Sundberg & Michael, 2001). Mands, which are the most elementary forms of verbal behavior, allow individuals to begin to contact social contractual contingencies;…

In the current investigation, we reviewed the literature on mand training for individuals with intellectual and developmental disabilities (IDD) in schools. Ninety-three studies met our inclusion criteria including 225 individual participants. Data were extracted related to participant demographics (e.g., age, disability, response form) and study…

One measure of success for interventions treating problem behavior is the effects achieved in the face of a challenge (e.g., changes in reinforcement schedules, lapses in treatment integrity); one hopes to demonstrate persistence of appropriate alternatives and the absence of resurgence of target behaviors. The present study successfully treated…

Augmentative and alternative communication (AAC) refers to a wide range of aided and unaided modes that are employed with a diverse group of people to support a range of language and communication outcomes. Children whose comprehension of spoken language greatly exceeds their ability to express themselves within that modality can be described as…

Sundberg and Michael (2011) reviewed the contributions of Skinner's (1957) "Verbal Behavior" to the treatment of language delays in children with autism spectrum disorder (ASD) and discussed several aspects of interventions, including mand training, intraverbal repertoire development, and the importance of using Skinner's taxonomy of…

Recently, there has been a proliferation of research on the functional independence of two of Skinner's (1957) verbal operants, the mand, and the tact. This research has produced highly variable results. In this article, we provide a critical review of the literature on mand-tact independence, a literature that has implications for both theory and…

The purpose of the present study was to assess whether intraverbal behavior, in the form of answers to questions, emerges as a result of listener training for five children diagnosed with autism. Listener responses were targeted and taught using prompting and differential reinforcement. Following successful acquisition of listener responses, the…

The purpose of the current paper is to describe the impact of applied behaviour analysis on language treatment for children with autism spectrum disorders (ASDs) diagnoses. Specifically, this paper will describe Skinner's theory of verbal behaviour and its contributions to evidence-based treatments for communication deficits among individuals with…

In Experiment 1, I conducted a functional analysis of student rate of learning with and without a peer-yoked contingency for 12 students in Kindergarten through 2nd grade in order to determine if they had conditioned reinforcement for collaboration. Using an ABAB reversal design, I compared rate of learning as measured by learn units to criterion…

This study aimed to teach individuals with autism spectrum disorder (ASD) and limited vocal speech to emit target vocalizations while using a speech-generating device (SGD). Of the 4 participants, 3 began emitting vocal word approximations with SGD responses after vocal instructional methods (delays, differential reinforcement, prompting) were…

In the following paper, two experiments are reported based on the relation between adult approvals as conditioned reinforcers and the number of vocal verbal operants, specifically tacts, mands, wh questions, sequelics, and conversational units emitted by children diagnosed with developmental disabilities. In Experiment I, following an experimental…
