The purpose of the study was to experimentally model summation in convergent multiple control over selection-based verbal behavior. Eight undergraduate students participated. In divergent--convergent tact training, a three-choice match-to-sample task was used to establish two selection-based tacts for each of five pictorial stimuli. One textual…

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…

The autoclitic is among the least studied and most complex verbal operant named and described by Skinner. The descriptive autoclitic is one subtype, which among other functions can describe the strength of the response. If the clarity of the stimulus is one source of response strength for tacts, manipulating stimulus clarity should evoke different…

The use of autoclitics can influence the behavior of individuals making choices when responding to a survey (e.g., checking or unchecking a box). In two studies, we investigated the effects of autoclitics as "nudges" on choice by manipulating different frames (opt-in and opt-out) and default options (i.e., unchecked and checked boxes).…

This systematic review evaluated the effects of foreign tact training on emergent learning outcomes in ten published studies. We also conducted a meta-analysis of aggregate data from seven studies comparing outcomes of foreign tact training with other verbal operant procedures. The preliminary findings indicated foreign tact training produced…

Since Skinner's conceptualization of the mand, applied behavior analysis researchers have used the concept to develop stimulus control transfer procedures effective for addressing manding deficits. More recently, researchers have explored the clinical utility of reinforcing mand variability during mand training and functional communication…

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…

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…

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…

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…

Mands for information (MFIs) play an important role in language development and are important for successfully acquiring new information from one's environment. Yet many individuals with autism do not acquire mands for information without direct teaching. Research has demonstrated effective procedures for teaching all "wh" forms, except…

Members (behaviors) of a response class are equivalent in that they produce the same functional reinforcer. Oftentimes, some members of a response class occur at higher rates than others. This can be problematic when the members that occur at high rates are socially inappropriate (e.g., self-injury, aggression, or disruption). The participant in…
