Complications travel: A cross‐cultural comparison of the proportion of complications as a verbal cue to deceit

Verbal lie detection tools are almost exclusively examined in Western Europe and North America, but practitioners worldwide show interest in such tools. Because cultural differences in the efficacy of such tools may occur, it is important to examine their efficacy in different cultures. In this article, we focus on proportion of complications, which in previous research was more diagnostic than “total details” in two British samples and in three samples that each included Hispanic, Russian, and South Korean participants. In the present article, we merged the three non‐British samples and analysed the data by presenting them for each cultural group separately. Truth tellers disclosed the details of a trip away they had made, whereas liars fabricated such details. Proportion of complications discriminated truth tellers from liars in all three groups and was consistently a better indicator of veracity than total details. Implications of the findings are discussed.     

The importance of multiple exemplar instruction in the establishment of novel verbal behavior

According to traditional linguistic accounts language, and its generative nature, cannot be taught. From a behavior analytic perspective, language is like any other behavior; it is learned and amenable to change. Based upon Skinner's radical behavioral analysis of verbal behavior, specific procedures have been designed to promote novel verbal relations. However, despite the strength and utility of this approach, using behavioral principles to understand the generativity of language has been challenging. Dependent upon the specific theory (e.g., stimulus equivalence, relational frame theory, bidirectional naming) within the radical behavioral orientation, researchers arrange unique procedures to evaluate the variables responsible for this phenomenon. This paper presents the commonalities and differences of two procedures (i.e., multiple exemplar training, multiple exemplar instruction) with examples of research highlighting the use of both in producing generativity. Further, it describes how multiple exemplar instruction is independent from other procedures leading to this outcome, and concludes by providing recommendations for both research and practice.     

Teaching children with autism to mand for social information

We replicated Shillingsburg et al. (2018) by teaching children with autism to mand for social information while analyzing the variables influencing the emission of mands. We presented questions about a social partner that were known and observable (e.g., “What is Robin doing?”), known but unobservable (i.e., questions for which an intraverbal response had previously been taught, such as, “Where does Robin work?”), or unknown (e.g., “What is Robin's favorite food?”). Correct answers were reinforced across all conditions. During treatment, we prompted children to mand for information from the social partner following only unknown questions. All children acquired mands for social information and answered previously unknown questions correctly after manding for social information and 3 of 4 participants emitted mands to novel social partners, including a peer with autism.     

An inter-subjective multi-factorial model of auditory verbal hallucinations in schizophrenia

Auditory verbal hallucinations (AVHs) are perceptive-like experiences happening without appropriate stimuli that in individuals with schizophrenia very often feature distressing contents. AVH frequently interfere with social relationships or result in dangerous behaviours. We hypothesize that in schizophrenia several vulnerability factors, especially when a subject is engaged in real or represented interpersonal transactions, lead to the appearance of AVHs, and favour their self-perpetuation over time. We analyse the different psychological factors that, according to empirical studies and clinical experience with persons with schizophrenia, seem involved in the genesis of AVHs. Several vulnerability factors appear to interact with situational ones to trigger AVHs: a) a facilitation of neural transmission from the premotor regions to the perceptual ones; b) a difficulty attuning with others, c) interpersonal schemas, provoking emotional suffering, intrusive thoughts and rumination; d) metacognitive dysfunctions. Once AVHs have appeared, further factors promote their perpetuation over time: a) cognitive factors like ruminative processing on AVHs, b) metacognitive beliefs about AVHs. An integrated theoretical model of AVHs is described and ideas for its empirical testing are suggested.     

Verbal interactions of aggressively and nonaggressively predisposed males in a drinking situation

The effects of progressive intoxication were studied in male social drinkers classified from prior histories as either aggressively (A) or nonaggressively (NA) predisposed while intoxicated. Two groups of two A and two NA subjects engaged in videotaped group discussions that were analyzed by Bales interaction process analysis (IPA). At comparable levels of ad libitum alcohol intake in a natural drinking environment, significantly more verbal activity was displayed by the A subjects than by the NA subjects (P <.001), including IPA category D (P <.025). The A subjects tended to address the group as a whole rather than individual members (P <.001) and NA subjects rather than other A subjects (P <.01). Free testosterone levels assessed from saliva were higher among A subjects than among NA subjects (P <.05) with no significant changes related to time and progressive intoxication. The results suggest that the tendency to behave aggressively while intoxicated may be a fairly stable individual trait, possibly related to androgen levels and active or coercive modes of social communication.     

Effects of mand-tact versus tact-only training on the acquisition of tacts

We sought to replicate and extend Carroll and Hesse's (1987) study of the acquisition of tacts by including participants with and without developmental disabilities. As in Carroll and Hesse, the present results showed that mand-tact training, rather than tact-only training, led to more rapid acquisition of tacts. Tacting on follow-up tests did not differ. In addition, our results show that mand-tact training established both verbal operants involved about as rapidly as tact-only training established only one verbal operant. DESCRIPTORS: verbal behavior, tact acquisition, mand-tact training, tact-only training, follow-up     

FUNCTIONAL ANALYSIS AND TREATMENT OF INAPPROPRIATE VERBAL BEHAVIOR

The present study examined the possible function of inappropriate verbal behavior of an adult man who had been diagnosed with both mental retardation and psychosis. Results of a functional analysis indicated that inappropriate verbal utterances were maintained by attention. An intervention consisting of the differential reinforcement of appropriate verbal behavior effectively reduced the inappropriate behavior.     

高述情障碍者的情绪图式特征

采用混合实验设计,以情绪词和情绪图片为实验材料,选取不同述情障碍得分的大学生为被试,通过三个实验考察了高述情障碍者的情绪图式特征。研究结果发现：（1）高述情障碍组被试对情绪词的效价判断反应时显著长于低述情障碍组,述情障碍各维度得分均与情绪词的效价判断反应时呈显著正相关;（2）高述情障碍组被试对情绪图片的效价判断反应时与低述情障碍组相比差异不显著;（3）高述情障碍组被试情绪图式联结所需反应时显著长于低述情障碍组,情感描述困难与情绪图式联结所需反应时之间相关显著。研究结论如下：高述情障碍者存在情绪语言图式和参考性链接上的缺陷,而在情绪意象上并不存在积极/消极区分能力方面的缺陷     

Nonmonotonic conditionals that behave like conditional probabilities above a threshold

I'll describe a range of systems for nonmonotonic conditionals that behave like conditional probabilities above a threshold. The rules that govern each system are probabilistically sound in that each rule holds when the conditionals are interpreted as conditional probabilities above a threshold level specific to that system. The well-known preferential and rational consequence relations turn out to be special cases in which the threshold level is 1. I'll describe systems that employ weaker rules appropriate to thresholds lower than 1, and compare them to these two standard systems.
