Instructive feedback (IF) involves incorporating additional acquisition targets into skill-acquisition programs. A recent study by Frampton and Shillingsburg (2020) found that IF led to emergent verbal operants with two elementary-aged children diagnosed with autism spectrum disorder (ASD). The current study replicated Frampton and Shillingsburg…

Language delays are commonly displayed by children on the autism spectrum. To help facilitate the development of verbal behavior, practitioners often implement intensive one-on-one, face-to-face instruction. However, the COVID-19 pandemic hindered typical face-to-face service delivery and caused practitioners to assess alternative approaches to…

Previous research has investigated generalized intraverbal-tacting by teaching children with autism to respond using autoclitic frames. The present study compared the effectiveness and efficiency of a Frame and a No Frame procedure across counterbalanced stimulus sets with 4 children with autism. In the Frame condition, children were taught to…

The current study evaluated a procedure used to teach two children with autism to ask "why" questions maintained by causal information about an event. To increase the value of information as a reinforcer, the experimenter denied access to preferred items and did not provide a reason for the denial. Participants were taught to ask…

For speakers belonging to multiple verbal communities, functional analyses of verbal behavior allow for dynamic control over response topography. The simple practice of allowing the speaker the freedom to select the language of instruction minimizes cultural bias and hegemony. We extended the research on functional analyses of verbal behavior to…

Parents play a significant role in the educational development of their children. However, there is little research around utilizing parents to collect data on their children's language skills. In particular, children with autism oftentimes demonstrate delays in the acquisition and use of language. Having information on a child's language…

Tact is the most important verbal operant (Skinner, 1957) due to the uniqueness of stimulus control and its role in facilitating acquisition of another verbal (e.g., mands, intraverbals) and nonverbal (i.e., listener) operants (Sundberg, 2015). Teaching tacts to children with ASD and the research on this area, however, are largely focused on…

This study examined the effects of presession attention on the acquisition of tacts (Experiment 1) and intraverbals (Experiment 2) in children diagnosed with autism. Each participant experienced 3 conditions. In the first 2 conditions, participants experienced a 15-min interval of either presession attention (PA) or no presession attention (NPA)…

We examined emergent tact control following stimulus pairing, using 2 different stimulus presentation arrangements. In the word-first condition, presentation of the auditory stimulus preceded the visual stimulus, and in the image-first condition, the visual stimulus preceded the auditory stimulus. Eight children (2-5 years old) participated. In…

Children with autism spectrum disorder (ASD) who have limited spoken communication skills are commonly taught to mand by exchanging picture symbols. Competent manding via symbol exchange relies on conditional discrimination--that is, selecting the picture symbol that corresponds to the desired reinforcer. Picture Exchange Communication System…

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…

A child's early language environment, and their parents' active engagement during parent-child interactions play a vital role in facilitating the development of complex social reinforcers and the growth of their verbal behavior. Using a verbal behavioral approach, this study aimed to measure the statistical significance of changes in the quality…

For most children with autism spectrum disorder (ASD), manding for information is an important skill that must be systematically taught. Although previous studies have evaluated interventions for teaching other mands for information, to date no studies have demonstrated effective procedures for teaching the mand "why?" The purpose of the…

A goal of behavior-analytic interventions is to produce behavior that is maintained under naturalistic conditions. In this experiment, we studied the effects of a speaker immersion protocol (SIP) on the number of speaker responses (tacts and mands) emitted by 3 preschool students under naturalistic, not directly targeted, conditions. During the…

The current study combined equivalence-based instruction and instructive feedback (IF) with two groups of children with autism spectrum disorder. For group 1, three sets of three targets were tested, and for group 2, two sets of three targets were tested. For each target stimulus, the following verbal operants were evaluated: (1) tact name, (2)…
