Abstract
This study examined strategies designed to increase the rate of targeted, low-probability mands in a concurrent operant environment. We examined the effects of schedule manipulations, prompt manipulations, motivating operation manipulations, and combined behavioral process manipulations. Increases in target mands were produced for all 8 participants. Schedule manipulations were effective in producing increased rates of targeted mands for 3 of 8 participants, whereas prompt manipulations were effective for 4 of 8 participants. Motivating operation manipulations were effective in producing increased rates of targeted mands for 2 of 8 participants and combined behavioral process manipulations were effective for the single participant exposed to the combination.

Abstract
The current study replicated and extended the findings of Wallace, Iwata, and Hanley (2006), who demonstrated conditions that facilitated the transfer from tact to mand relations. Students in the current study were taught to tact both high-preference (HP) and low-preference (LP) items and subsequently were assessed on their ability to mand for those items. The results showed the emergence of mands for HP items but not LP items following tact training.

Abstract
Mand training is often a primary focus in early language instruction and typically includes mands that are positively reinforced. However, mands maintained by negative reinforcement are also important skills to teach. These include mands to escape aversive demands or unwanted items. Another type of negatively reinforced mand important to teach involves the removal of a stimulus that prevents access to a preferred activity. We taught 5 participants diagnosed with autism spectrum disorders to mand for the removal of a stimulus in order to access a preferred item that had been blocked. An evaluation was conducted to determine if participants responded differentially when the establishing operations for the preferred item were present versus absent. All participants learned to mand for the removal of the stimulus exclusively under conditions when the establishing operation was present.

Abstract
Mand training is an essential component of verbal behavior training for any individual who lacks this skill. The current study replicates and extends, with some procedural differences, the work of Hall and Sundberg (1987) by using an interrupted chain procedure to teach mands for missing items to children with autism. The participants were 3 children with autism, ranging between 5 and 8 years of age, who would regularly mand for a wide variety of reinforcers when they were present but would rarely mand for items that were not in sight (i.e., missing items). Participants were first taught to complete 3 behavior chains. Subsequently, the chains were interrupted by removing 1 item needed to complete each chain to contrive motivating operations (MOs) as a means of teaching mands for missing items. Following mand training incorporating vocal prompt and prompt fading procedures, all participants emitted unprompted mands for the missing items within the context of the trained chains and within the context of novel, untrained chains. After teaching mands for missing items, probes were conducted to test for untrained tact acquisition. All participants also demonstrated tact responses relative to the missing items as a result of the mand training.

Abstract
We evaluated differential reinforcement of alternative behavior (DRA) plus prompting to increase peer-directed mands for preferred items using a picture exchange communication system (PECS). Two nonvocal individuals with autism participated. Independent mands with a peer increased with the implementation of DRA plus prompting for both participants. In addition, peers engaged in brief social interactions following the majority of mands for leisure items. These results suggest that teaching children to use PECS with peers may be one way to increase manding and social interactions in individuals with limited or no vocal repertoire.

Abstract
Naming is a verbal developmental capability and cusp that allows children to acquire listener and speaker functions without direct instruction (e.g., incidental learning of words for objects). We screened 19 typically developing 2- and 3-year-old children for the presence of Naming for 3-dimensional objects. All 9 3-year-olds had Naming, and 8 of 10 2-year-olds lacked Naming. For the 2-year-old children who lacked Naming, we used multiple-probe designs (2 groups of 4 children) to test the effect of multiple exemplar instruction (MEI) across speaker and listener responses on the emergence of Naming. Prior to the MEI, the children could not emit untaught listener or speaker responses following match-to-sample instruction with novel stimuli, during which they had heard the experimenter tact the stimuli. After MEI with a different set of novel stimuli, the children emitted listener and speaker responses when probed with the original stimuli, in the absence of any further instruction with those stimuli. Seven of 8 children acquired the speaker and listener responses of Naming at 83% to 100% accuracy. We discuss the basic and applied science implications.

Abstract
We assessed the maintenance of newly acquired mands under presession reinforcer access (reinforcer efficacy abolished) and no presession reinforcer access (reinforcer efficacy established) conditions with 3 children with autism spectrum disorder. Results suggested that the no presession access condition established the value of the reinforcer and evoked responding relative to the presession access condition. Results are discussed in the context of implications for assessing maintenance of previously acquired skills.

Abstract
Research on the functional independence of verbal operants (Skinner, 1957) has demonstrated inconsistent findings. One explanation may be that these studies have not manipulated the motivating operation (MO) to facilitate the emergence of mands (Hall & Sundberg, 1987; Lamarre & Holland, 1985). In the current study, 1 participant, diagnosed with autism, was taught to tact high-preference and low-preference leisure items, and emergence of mands was tested under varying MO conditions. Results showed the emergence of mands following periods of arranged deprivation, and greater maintenance for a highly preferred relative to a less preferred stimulus. However, mands only emerged when presession tact trials were conducted. These results suggest that in a state of deprivation, transfer of stimulus control from discriminative to motivational conditions may occur without direct training.

Abstract
The current investigation evaluated the effects of extinction and prompts on training and generalization of peer-directed mands for preferred items using a picture exchange communication system with 2 children diagnosed with autism. Results showed that independent mands with a peer increased during treatment for both participants, generalized to a novel peer without explicit training for 1 participant and following training for the second participant, and maintained in a more naturalistic setting that simulated a free-play activity in a classroom.

Abstract
The effects of contriving motivating operations (MOs) and script fading on the acquisition of the mand "Where's [object]?" were evaluated in 2 boys with language delays. During each session, trials were alternated in which high-preference items were present (abolishing operation [AO] trials) or missing (establishing operation [EO] trials) from their typical locations. Both participants learned to mand during EO trials and not to mand during AO trials during training. Generalization of manding was demonstrated across novel instructors, stimuli, and settings and maintained 3 to 4 weeks following the intervention.

Abstract
This study sought to examine the effects of training mands on the emergence of tacts with the same response forms. Results indicated that training adjective sets as mands resulted in the emergence of adjective sets as tacts under modified, but not standard, antecedent conditions. The findings suggested that the apparent functional independence of mands and tacts may be explained by a lack of appropriate antecedent control over responding.

Abstract
The production of verbal operants not previously taught is an important aspect of language productivity. For Skinner, new mands, tacts, and autoclitics result from the recombination of verbal operants. The relation between these mands, tacts, and autoclitics is what linguists call analogy, a grammatical pattern that serves as a foundation on which a speaker might emit new linguistic forms. Analogy appears in linguistics as a regularity principle that characterizes language and has been related to how languages change and also to creativity. The approaches of neogrammarians like Hermann Paul, as well as those of Jespersen and Bloomfield, appear to have influenced Skinner's understanding of verbal creativity. Generalization and stimulus equivalence are behavioral processes related to the generative grammatical behavior described in the analogy model. Linguistic forms and grammatical patterns described in analogy are part of the contingencies of reinforcement that produce generalization and stimulus equivalence. The analysis of verbal behavior needs linguistic analyses of the constituents of linguistic forms and their combination patterns.

Abstract
Previous studies have identified a number of effective teaching procedures to increase verbal behavior in individuals with developmental disabilities. However, few studies have evaluated modifications of treatment procedures when children fail to acquire communication skills. In the present investigation, a 4-year-old boy with autism failed to acquire unprompted mands and tacts during mand-only and tact-only training. Results indicated that combining echoic training with mand or tact training increased unprompted manding and tacting.

Abstract
Children with autism and related disabilities frequently fail to develop echoic repertoires. Among the ways in which treatment approaches vary is the extent to which automatic reinforcement is utilized. The present experiment was designed to test the efficacy of a procedure that incorporates automatic reinforcement and socially mediated reinforcement in the development of an echoic repertoire. The implementation of this treatment package resulted in an increase in the vocal play and echoic behavior for two participants, each of whom had very limited verbal repertoires. The study was conducted as a multiple probe across sounds design. Vocal play for Participant 1 increased from baseline rates as low as .2 per min to 4.5 per min during treatment, and her percent correct echoic behavior increased from 0% to at least 90% on both sounds. Participant 2 showed rapid gains in echoic control on one sound before requiring dismissal from the study. Interobserver agreement on the occurrence of target vocals equaled 100%. The results of this study have implications for which procedures to use in the establishment of echoic, echoic mand, and mand repertoires.

Abstract
In Verbal Behavior,Skinner (1957) provided a conceptual framework and taxonomy for the controlling variables of language that defined independent verbal operants by their functional relations to antecedents and consequences (rather than by topography or meaning). Although professional interest in this area has recently increased within the behavior analytic community, Skinner's conceptual framework may not yet have fully impacted the experimental literature. This quantitative review of the literature examined the studies on verbal behavior that were empirical in nature, concerned with human verbal behavior, and addressed at least one verbal operant (e.g., mand, tact, echoic, autoclitic, and/or intraverbal behavior) within the experiment. The results of this review suggest that a growing body of research exists to support many of the tenets of Skinner's conceptualization and taxonomy but many areas of verbal behavior research have yet to be addressed. Continued research in this area is crucial for the development and implementation of effective verbal behavior interventions for people with disabilities.

Abstract
According to Skinner's (1957) analysis of verbal behavior, the mand and the tact are functionally independent verbal operants, each of which is acquired through a unique history of reinforcement. The present study attempted to replicate the findings of Lamarre and Holland (1985), who empirically demonstrated functional independence of mands and tacts in typically developing preschool children. Five children participated. All were initially trained to complete two 4-piece assembly tasks. Four children were then trained to tact the four pieces that comprised one of the assembly tasks, and to mand for the four pieces that comprised the other task, using arbitrary vocal response forms. The remaining child received tact training only, and only on one task. The effects of training on the untrained operant were evaluated in a multiple-probe design across tasks. Following mand training, 4 out of 4 children reliably emitted tacts under testing conditions, while the effects of tact training differed across participants. The results differ from those of Lamarre and Holland, but are not necessarily surprising from the point of view of either Skinner's analysis or more recent behavioral accounts of language. Future research should attempt to identify variables that affect transfer between mand and tact relations.

Abstract
The purpose of this project was to demonstrate untrained vocal requests in three adults with severe developmental disabilities. Specifically, we evaluated whether a history of reinforced relational responding would give rise to untrained vocal requests for novel items. Participants were first taught to request preferred items using their category names. They were then taught conditional discriminations between pictures of preferred items that were categorically related. Finally, participants were tested for their abilities to request items that had not been originally presented during request training, using their category names. All participants demonstrated untrained requests, and for some participants, changes in the mand repertoire were accompanied by changes in the tact repertoire. Some participants also showed generalization of skills across settings.
