Erratum to: Token Reinforcement of Verbal Responses Controlled by Temporally Removed Verbal Stimuli

In the present study we examined the effects of token reinforcement on the convergent control of immediate and temporally removed verbal stimuli over the verbal behavior of three school-age children with autism who showed specific deficits in intraverbal responding. Throughout the study, participants were systematically introduced to a series of visitors to a university-based autism center, and subsequently probed for information about the visitor they had most recently met. Results show that contingent token reinforcement was effective at establishing control by temporally removed verbal stimuli.     

Why Do Some Toddlers Help A Stranger? Origins of Individual Differences in Prosocial Behavior

This study investigated the influence of emotion on toddlers' prosocial behavior in instrumental helping tasks with an unfamiliar adult. The goals were to examine whether early prosocial behavior was affected by (1) the adult's expressions of sadness (in contrast to a neutral expression) as a cue of need and (2) toddlers' emotion understanding. Thirty‐five 18‐ to 20‐month‐olds participated in eight trials in which an experimenter either indicated need for assistance (experimental condition) or did not (control). In addition, the experimenter expressed either sadness or neutral affect in each trial. Toddlers' emotion understanding was assessed using maternal reports of children's emotion words. The experimenter's emotional expression alone was not associated with prosocial behavior, but toddlers helped more in experimental than control conditions. However, toddlers with larger emotion word vocabularies were marginally more prosocial when the experimenter expressed sadness, and girls provided more assistance than boys in experimental conditions. These findings highlight the complex influences of emotion on early prosocial motivation.     

A Functional Analysis of Gestural Behaviors Emitted by Young Children With Severe Developmental Disabilities

Many children with severe developmental disabilities emit idiosyncratic gestures that may function as verbal operants (Sigafoos et al., 2000). This study examined the effectiveness of a functional analysis methodology to identify the variables responsible for gestures emitted by 2 young children with severe developmental disabilities. Potential verbal operants for each participant were functionally analyzed using a multi-element design. Results indicate that gestures were maintained by access to tangible items or the delivery of information about novel stimuli. This study extends the use of functional analysis to identify conditions under which children with developmental disabilities emit gestural verbal behavior.     

Natural implementation in public goods economies

In this paper, we identify necessary and sufficient conditions for social choice correspondences to be Nash implemented by “natural” mechanisms in economies with arbitrary numbers of private and public goods. We find that when there exist only one public good and an arbitrary number of private goods, the Lindahl correspondence is implementable by a natural quantity mechanism in which each agent announces his own consumption bundle of private goods and input vectors for public goods. However, regardless of the numbers of private and public goods, the Pareto correspondence is not implementable even by any natural price ⁿ -quantity mechanism in which each agent reports a price vector of private goods and all agents’ personalized price vectors of public goods, in addition to his own consumption bundle of private goods and input vectors for public goods.     

Establishing Naming in Typically Developing Two-Year-Old Children as a Function of Multiple Exemplar Speaker and Listener Experiences

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.     

Antecedents and Consequences of Words

As instances of behavior, words interact with environments. But they also interact with each other and with other kinds of behavior. Because of the interlocking nature of the contingencies into which words enter, their behavioral properties may become increasingly removed from nonverbal contingencies, and their relationship to those contingencies may become distorted by the social contingencies that maintain verbal behavior. Verbal behavior is an exceedingly efficient way in which one organism can change the behavior of another. All other functions of verbal behavior derive from this most basic function, sometimes called verbal governance. Functional verbal antecedents in verbal governance may be extended across time and space when individuals replicate the verbal behavior of others or their own verbal behavior. Differential contact with different verbal antecedents may follow from differential attention to verbal stimuli correlated with consequential events. Once in place, verbal behavior can be shaped by (usually social) consequences. Because these four verbal processes (verbal governance, replication, differential attention, and verbal shaping) share common stimulus and response terms, they produce interlocking contingencies in which extensive classes of behavior come to be dominated by verbal antecedents. Very different consequences follow from verbal behavior depending on whether it is anchored to environmental events, as in scientific verbal practices, or becomes independent of it, as in religious fundamentalism.     

A Behavior Analytic Analogue of Learning to Use Synonyms,Syntax, and Parts of Speech

Matching-to-sample and sequence training procedures were used to develop responding to stimulus classes that were considered analogous to 3 aspects of verbal behavior: identifying synonyms and parts of speech, and using syntax. Matching-to-sample procedures were used to train 12 paired associates from among 24 stimuli. These pairs were analogous to synonyms. Then, sequence characteristics were trained to 6 of the stimuli. The result was the formation of 3 classes of 4 stimuli, with the classes controlling a sequence response analogous to a simple ordering syntax: first, second, and third. Matching-to-sample procedures were then used to add 4 stimuli to each class. These stimuli, without explicit sequence training, also began to control the same sequence responding as the other members of their class. Thus, three 8-member functionally equivalent sequence classes were formed. These classes were considered to be analogous to parts of speech. Further testing revealed three 8-member equivalence classes and 512 different sequences of first, second, and third. The study indicated that behavior analytic procedures may be used to produce some generative aspects of verbal behavior related to simple syntax and semantics.     

An Analysis of Verbal Stimulus Control in Intraverbal Behavior: Implications for Practice and Applied Research

A common characteristic of the language deficits experienced by children with autism (and other developmental disorders) is their failure to acquire a complex intraverbal repertoire. The difficulties with learning intraverbal behaviors may, in part, be related to the fact that the stimulus control for such behaviors usually involves highly complex verbal stimuli. The antecedent verbal control of intraverbal behavior may involve discriminative stimuli (i.e., discriminated operants), conditional stimulus control, and/or control by compound stimuli. Distinctions among these different types of antecedent control are presented, along with recommendations for intervention procedures that may facilitate the acquisition of intraverbal behavior.     

The Use of Instructive Feedback to Promote Emergent Tact and Intraverbal Control: A Replication

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 with two children with ASD. Therapists conducted sessions of mastered listener-by-name trials (e.g., “Show me otter,” with pictures of otter, dog, and elephant) with IF statements for features of the target stimuli (e.g., “It lives in rivers.”) embedded during the consequence portion of the trial. We evaluated the acquisition of secondary targets and emergent responses using a concurrent multiple baseline across sets design. We observed increased correct responding for secondary targets and emergent responses for all three sets of stimuli with one participant. The other participant emitted correct responses for secondary targets and emergent operants with the first set but not with the other two sets of stimuli. Results suggested that IF can lead to emergent verbal operants, but the extent of emergence may be idiosyncratic.Supplementary InformationThe online version contains supplementary material available at 10.1007/s40616-022-00171-y.     

Consumer Evaluation Research: Implications for Methodology,Social Policy,and the Role of the Sociologist*

Consumer evaluation research is defined and analyzed as an experimental model for establishing a link between social science research and public policy. The paper reports the results of an 18-month longitudinal study of an experimental citizen evaluation group. Participant observation was the method used to organize the data. The impact of the model on methodological issues, such as objectivity, researcher autonomy, and control over research decision-making, is discussed. Implications of the CER model for integrating social research and public policy formulation are analyzed.     

The Interaction of Sex,Verbal, and Nonverbal Cues in Same-Sex First Encounters

This experiment examined sex differences in responses to various combinations of verbal and nonverbal content during a same-sex interaction. Fifty men and thirty women participated in a same-sex interview task with a confederate posing as another participant. Confederates disclosed either superficial or emotional information, and they faced away from or toward the participant, when answering questions. Results revealed that men attended to verbal information to evaluate the appropriateness of their own personal disclosure, whereas women attended to both verbal and nonverbal cues to evaluate the conversation partner and the appropriateness of their own personal disclosure.     

A Comparison of Stimulus-Stimulus Pairing,Standard Echoic Training,and Control Procedures on the Vocal Behavior of Children With Autism

An alternating treatments design was employed to compare the effect of stimulus-stimulus pairing, standard echoic training, and a control condition on the vocal behavior of 3 preschoolers with autism. Data were recorded during pre- and postsession observations. During the stimulus-stimulus pairing condition, the experimenter''s vocal model was paired with the delivery of a preferred item. During the standard echoic training condition, the experimenter presented a vocal model and delivered a preferred item contingent on an echoic response. During the control condition, the experimenter presented a vocal model and, after a 10-s delay, presented a preferred edible item. Results from the post-session observations during the stimulus-stimulus pairing condition showed an immediate but temporary increase in the target sound for 1 participant only. Implications and suggestions for future research are provided.     

The Effect of Social Presence on the Facial and Verbal Expression of Emotion and the Interrelationships Among Emotion Components

Women were videotaped while they spoke about a positive and a negative experience either in the presence of an experimenter or alone. They gave self-reports of their emotional experience, and the videotapes were rated for facial and verbal expression of emotion. Participants spoke less about their emotions when the experimenter (E) was present. When E was present, during positive disclosures they smiled more, but in negative disclosures they showed less negative and more positive expression. Facial behavior was only related to experienced emotion during positive disclosure when alone. Verbal behavior was related to experienced emotion for positive and negative disclosures when alone. These results show that verbal and nonverbal behaviors, and their relationship with emotional experience, depend on the type of emotion, the nature of the emotional event, and the social context.     

Effect of training different classes of verbal behavior to decrease aberrant verbal behavior

Inappropriate verbal behavior that is labeled "psychotic" is often described as insensitive to environmental contingencies. The purpose of the current study was to establish different classes of rational or appropriate verbal behavior in a woman with developmental disabilities and evaluate the effects on her psychotic or aberrant vocal verbal behavior. Similar to a previous study (Arntzen, Ro Tonnessen, & Brouwer, 2006), the results of the current study suggested that the procedure helped to establish a repertoire of appropriate functional vocal verbal behavior in the participant. Overall, the results suggested the effectiveness of an intervention based on training various classes of verbal behavior in decreasing aberrant verbal behavior.     

Grammatical constructions in typical developing children: effects of explicit reinforcement, automatic reinforcement and parity

This study replicated and extended Wright (2006) and Whitehurst, Ironsmith, and Goldfein (1974) by examining whether preschool aged children would increase their use of passive grammatical voice rather than using the more age-appropriate active grammatical construction when the former was modeled by an adult. Results showed that 5 of the 6 participants began using the passive voice after this verbal behavior had been modeled. For 3 of the participants, this change was large. The change occurred even though the adult model explicitly rewarded the participant with praise and stickers for using the active voice, while providing no praise or stickers for using the passive form that was modeled. For 1 participant, the modeling procedure had no effect on use of the passive voice. These results indicate a strong automatic reinforcement effect of achieving parity with the grammatical structures used by adults, compared to the effects of explicit reinforcement by the adult. This might help to explain why children acquire grammatical structures prevalent in their language community apparently without explicit instruction.     

The Effects of a Stimulus-Stimulus Pairing Procedure on the Unprompted Vocalizations of a Young Child Diagnosed with Autism

The current study evaluated the effects of a stimulus-stimulus pairing procedure intended to increase spontaneous vocalizations of a young child diagnosed with autism. A multiple-baseline design across two target phonemes was used to evaluate the effects of the pairing procedure on the frequency of phonemes uttered by the participant. Data were collected during presession, postsession, and follow-up periods across three conditions: Baseline, Control, and Pairing. During the Pairing conditions, a target phoneme was repeatedly vocalized by the experimenter and was systematically paired with preferred stimuli. Results from postsession observations following the pairing condition evidenced no increase in the target sounds. Practical and theoretical implications of the results are discussed.     

The development of synchronous text-based instant messaging as an online interviewing tool

The article reports the development of a synchronous text-based online interviewing tool with a continuity of private discussion that is not achieved in open-ended questionnaires, email interviews and online discussion boards. The participants were women who had undergone a surgical or natural menopause, who in a pilot interview highlighted the potential sensitivity of this subject and inspired the implementation of this method. The overall feedback was positive with the main advantages centred on feelings of anonymity, convenience and a more comfortable interview environment. Disadvantages included lack of body language and technical issues with computers. This technique ensures a degree of confidentiality while still obtaining depth of enquiry, where other qualitative methods potentially risk invading a participant’s privacy. It can be offered both alongside other interviewing techniques to allow participant choice and on its own when exploring sensitive and personal topics or when extra participant anonymity is appropriate.     

Effect of Normative Masculinity on Males’ Dysfunctional Sexual Beliefs,Sexual Attitudes,and Perceptions of Sexual Functioning

Male sexual dysfunction is a prevalent and distressing condition, which may be exacerbated by the sufferer's perceptions of masculinity and normative sexual behavior. This study sought to investigate the effect of social context on males’ beliefs regarding sexual behavior. The research examined the effect of male role modeling and masculine cues on males’ dysfunctional sexual beliefs, sexual attitudes, and self-perceptions of sexual functioning. A sample of 140 male participants, with a mean age of 29 years, was exposed to pictorial and verbal cues that presented different versions of male behavior across three conditions. Results indicated that males exposed to models and cues of traditional masculinity showed significantly increased levels of dysfunctional sexual beliefs and traditional sexual attitudes relative to males exposed to models of modern masculinity. Results also indicated that males exposed to traditional masculine stimuli reported lower levels of sexual inhibition due to fear of performance failure than males exposed to models of modern masculinity. The potential role of social context is discussed in the development and maintenance of male sexual dysfunction and its implications for treatment.     

Equivalence class formation in non-hearing impaired children and hearing impaired children

The relationship between verbal behavior and stimulus equivalence was examined using three sets of children differing in chronological age and verbal ability: (1) non-hearing impaired three and four year olds who had verbal skills generally consistent with their chronological ages; (2) partially hearing (severe to profoundly deaf) children who were rated with verbal ages of above 2 years; and (3) partially hearing children (also severely to profoundly deaf) who were rated with verbal ages of below 2 years. All children were taught a series of four conditional discriminations using unfamiliar stimuli. The children were then tested to determine whether classes of equivalent stimuli had formed. Although all the children were able to learn the conditional discriminations equally well and all the verbally-able children (normal and partially hearing) formed equivalence classes, only one of the verbally-impaired children reliably demonstrated stimulus equivalence formation. These results are consistent with the suggestion that stimulus equivalence and human verbal behavior are closely related.
