Rodriguez et al. (2022) discovered that teaching four component skills was sufficient to facilitate the emergence of intraverbal tacts across four applications with three participants. Our study replicated and evaluated an extension of this procedure that was directed at facilitating intraverbal tacts when a child learns the component skills but continues to fail to produce intraverbal tacts. The extension consisted of procedures to enhance the divergent control exerted by the auditory stimulus (i.e., the question) and the discriminability of joint control. Intraverbal tacts emerged for all three participants after undergoing the extension procedures. These results are discussed in the context of a conceptual analysis of intraverbal tacts and the potential role of joint control.

Autoclitics are secondary verbal operants that are controlled by a feature of the conditions that occasion or evoke a primary verbal operant such as a tact or mand. Qualifying autoclitics extend, negate, or assert a speaker's primary verbal response and modify the intensity or direction of the listener's behavior. Howard and Rice (1988) established autoclitics that indicated weak stimulus control (e.g., “like a [primary tact]”) with four neurotypical preschool children. However, generalization to newly acquired tacts was limited. In Experiment 1, we addressed similar behavior as in Howard and Rice but with autistic children while using simultaneous teaching procedures, and we observed generalization across sets and with newly acquired tacts. In Experiment 2, we evaluated the effects of multiple‐exemplar training on generalization of autoclitics across sets of naturalistic stimuli. Across participants, gradual increases in the frequency of autoclitics occurred with untaught stimuli after teaching with one or more sets.

Ecological validity refers to how closely an experiment aligns with real‐world phenomena. In applied behavioral research, ecological validity may guide decisions about experimental settings, stimuli, people, and other design features. However, inconsistent use of the term ecological validity in the published literature has led to a somewhat disjointed technology. The purposes of this paper were to review current uses of the term “ecological validity” in the Journal of Applied Behavior Analysis, propose ways to make a study more ecologically valid, and develop a checklist to assist in identifying the type and degree of ecological validity in any given study.

Young children break rules (i.e., transgress) and then lie about those transgressions. By adolescence, lying is associated with decreased trust, communication, and quality of relationships, and with befriending antisocial peers. To decrease lies, we replicated differentially reinforcing honest reports about transgressions for one 6‐year‐old neurotypical child and two 7‐year‐old children who were diagnosed with autism spectrum disorder. After all children learned to report honestly about transgressions, we extended past research to decrease transgressions by differentially reinforcing alternative play behaviors. For all children, this resulted in increased levels of play, decreased transgressions, and continued honesty about infrequent transgressions. Caregivers were satisfied with children's increased honest reports and decreased transgressions. The results support first reinforcing children's honest reports about transgressions and then decreasing transgressions to satisfying levels for caregivers.

Intraverbal tacts are an example of multiply controlled verbal behavior. More specifically, they are verbal responses under control of both a nonverbal (visual) stimulus (e.g., a green ball) and a verbal (auditory) stimulus (e.g., “What color?” vs. “What shape?”). Studies have shown that verbal behavior training can be arranged in a way that would lead to the emergence of other verbal operants, including multiply controlled (convergent) intraverbals. Our study sought to evaluate the relevance of a specific set of component skills on the emergence of intraverbal tacts in children with an autism spectrum disorder. Intraverbal tacts were observed only when all component skills were mastered, suggesting that this set of skills was sufficient to produce emergent verbal performance. Preliminary data were obtained on the necessity of 4 of the 6 component skills and tentatively suggest that they may be necessary to produce emergent intraverbal tacts, at least under some conditions.

This study assessed children's and caregivers' preferences for various arrangements of negative reinforcement, including differential negative reinforcement of an alternative behavior (DNRA), noncontingent escape (NCE), and escape extinction. In the first treatment comparison, the DNRA and NCE treatments similarly decreased problem behavior, but all 3 children preferred DNRA. By contrast, 3 of 4 caregivers preferred escape extinction, likely due to increased compliance in this condition. In a second treatment comparision with 1 child, a multiple schedule and then a chained schedule were introduced to increase the practically of the initial DNRA treatment. The child continued to prefer the treatment with contingent reinforcement in both comparisons, and his caregivers preferred the chained schedule. Results further support the selection of treatments that include contingent reinforcement, and the evaluation serves as a model for progressing through treatment options until child and caregiver preferences align.

Researchers have demonstrated the efficacy of picture prompts on the acquisition of intraverbals (Coon & Miguel in Journal of Applied Behavior Analysis, 45, 657–666, 2012; Goldsmith, LeBlanc, & Sautter in Research in Autism Spectrum Disorders, 1, 1–13, 2007; Ingvarsson & Hollobaugh in Journal of Applied Behavior Analysis, 44, 659–664, 2011; Ingvarsson & Le in The Analysis of Verbal Behavior, 27, 75–93, 2011; Miguel, Petursdottir, & Carr in The Analysis of Verbal Behavior, 21, 27–41, 2005; Partington & Bailey in The Analysis of Verbal Behavior, 11, 9–18, 1993). However, no one (to our knowledge) has determined the effects of picture prompts on the variability of responding during intraverbal categorization. We evaluated the use of a scenic picture prompt on response variability during the acquisition of intraverbal categorization with 4 children diagnosed with autism. All children mastered the task and initially demonstrated varied responding. However, responding eventually became invariant for all children. These results demonstrate the efficacy of a scenic picture prompt for teaching children with autism intraverbal categorization and for producing initial response variability. Additional research should be conducted to determine teaching procedures that promote continued varied responding for individuals with autism.

Under naturally occurring conditions, the individual who is the target of aggression is likely to physically react to evade the aggressor and avoid physical harm. Like other forms of attention that occur following problem behavior, physical reactions may maintain problem behavior. However, evaluating the effects of physical reactions is complicated by issues related to therapists' ability to consistently and safely control their reactions, which may prove difficult to achieve in functional analyses. We evaluated the utility of a concurrent‐operant analysis to test behavioral sensitivity to physical reactions. The results suggest that the concurrent‐operant analysis may be useful when therapists cannot consistently refrain from responding contingent on problem behavior in the control condition of a more typical functional analysis.

Despite its advantages, discrete‐trial instruction (DTI) has been criticized for producing rote responding. Although there is little research supporting this claim, if true, this may be problematic given the propensity of children with autism to engage in restricted and repetitive behavior. One feature that is common in DTI that may contribute to rote responding is the prompting and reinforcement of one correct response per discriminative stimulus. To evaluate the potential negative effects of rote prompts on varied responding, we compared the effects of modeling rote versus varied target responses during the teaching of intraverbal categorization. We also evaluated the effects of these procedures on the efficiency of acquisition of any one correct response. For all four children, any increase in varied responding was fleeting, and for two participants, acquisition was slower in the variable‐modeling condition.

Convergent intraverbals represent a specific type of intraverbal in which multiple components of one speaker's verbal behavior control a specific verbal response from another speaker (e.g., Speaker 1: What wooly, horned animal lives in the high country? Speaker 2: Bighorn sheep). To foster the development of advanced language, Sundberg and Sundberg (2011) proposed prerequisite skills that may engender the emergence of novel, convergent intraverbals. We used a multiple‐probe design with both nonconcurrent (across participants) and concurrent (across stimulus sets) components to evaluate the effects of training these prerequisite skills on the emergence of convergent intraverbals with four children with autism. Participants showed the emergence of convergent intraverbals at mastery levels after they displayed mastery performance on all of the prerequisite skills identified by Sundberg and Sundberg, lending support to their characterization as prerequisites. We discuss these findings in terms of operant mechanisms that may facilitate the development of generative language.

We taught three children diagnosed with autism spectrum disorder to request help using an interrupted chain procedure during which we manipulated task materials such that the child was either incapable or capable of independently completing a link of a behavior chain. We initially observed undesirable generalization of requests for help during capable trials when teaching was introduced during incapable trials for two participants and to a lesser extent for the third participant. However, with repeated exposure to differential prompting and reinforcement across incapable and capable trials, differential responding was observed across EO‐present and EO‐absent trials for all three participants during both teaching sets and one generalization set that was never exposed to teaching procedures. These findings suggest that it is important to consider the antecedent conditions under which the response should occur when teaching children to request help.
