Teaching conversational speech to children with autism spectrum disorder using text‐message prompting

The present study was designed to teach conversational speech using text‐message prompts to children with autism spectrum disorder (ASD) in home play settings with siblings and peers. A multiple baseline design across children was used. Children learned conversational speech through the text‐message prompts, and the behavior generalized across peers and settings. Maintenance of treatment gains was seen at 1‐month follow‐up probes. Social validity measures indicated that parents of typically developing children viewed the participants' conversational speech as much improved after the intervention. Results are discussed in terms of the efficacy of text‐message prompts as a promising way to improve conversational speech for children with ASD.     

The Effects of Relationship Closeness on the Communication of Stereotype-Relevant Information in Conversation

刻板印象信息常借助人际关系链得以沟通和传递。而沟通是一种社会情境活动,故人们对信息的沟通和传递依赖于沟通的社会背景,关系亲密度是其中的一个重要因素。关系亲密度指的是沟通者间相互依赖和了解的程度,以自我包含他人量表得分作为判断指标。本研究的目的即为扩展已有的刻板印象沟通研究,采用Ruscher等人提出的二人对话范式,通过两个实验探索关系亲密度如何影响人们在谈话过程中对刻板印象相关信息的沟通和传递。实验1中的关系亲密度由自然存在模式建构,共32对同性别被试参与;实验2中的关系亲密度由RCIT三阶段自我表露任务实验室诱发模式建构,共38对同性别被试参与。所用的沟通材料均为Klein 等 人编制的刻板印象信息故事,并使用自我包含他人量表检核关系亲密度。实验均为2×2×2三因素混合设计,其中,关系亲密度（陌生人和朋友）为被试间因素,刻板印象信息的一致性（SC一致信息与SI不一致信息）和故事情节的核心性（核心和次要）为被试内因素。在实验1中,三因素方差分析的结果显示,刻板印象信息的一致性主效应显著,核心性主效应显著,刻板印象信息的一致性和关系亲密度的交互作用显著。在陌生人关系条件下,被试传递的 SC 信息显著多于 SI 信息;而在朋友关系条件下,被试并没有显示出这种SC偏差,反而传递了稍多的SI信息。在实验2中,三因素方差分析的结果显示,刻板印象信息的一致性主效应边缘显著,核心性主效应显著,刻板印象信息的一致性和关系亲密度的交互作用显著。在陌生人关系条件下,被试传递的SC信息显著多于 SI 信息;而在朋友关系条件下,被试并没有显示出SC偏差,同样传递了稍多的SI信息。因此,可以认为人们倾向于向陌生人传递显著更多的刻板印象一致信息,而向朋友则未显示出这种特点。谈话中,关系亲密度影响刻板印象信息的沟通和传递。     

Effects of hands-free cellular phone conversational cognitive tasks on driving stability based on driving simulation experiment

Driver distraction due to cellular phone usage is a major contributing factor to road crashes. This study compares the effects of conversational cognitive tasks using hands-free cellular phone on driving performance under three distraction conditions: (1) no distraction (no cellular conversation), (2) normal conversation (non-emotional cellular conversation), and (3) seven-level mathematical calculations. A car-following scenario was implemented using a driving simulator. Thirty young drivers with an average age of 24.1 years maintained a constant speed and distance between the subject vehicle and a leading vehicle on the driving simulator, and then respond to the leading vehicle’s emergency stop. The driving performances were assessed by collecting and statistically analyzing several variables of maneuver stability: the drivers’ brake reaction times, driving speed fluctuation, car-following distance undulation, and car-following time-headway undulation. The results revealed that normal conversation on a hands-free cellular phone impaired driving performance. The degree of impairment caused by normal calculation was equivalent to the distraction caused by Level 3 mathematical calculations according to the seven-level calculation baseline. The calculation difficulty of Level 3 is one double-digit figure plus a single-digit figure, and non-carry addition mental arithmetic is required, e.g., 44 + 4. The results indicated that an increase in the level of complexity of the calculation task was associated with an increase in brake reaction time. The seven-level calculation-task baseline could be applied to measure additional distraction effects on driving performance for further comparison.     

Conversation on mental states at nursery: Promoting social cognition in early childhood

Despite growing evidence that conversation on inner states fosters gains in children’s social cognition, this mechanism has yet to be tested with toddlers. To address this gap, we examined whether an intervention based on conversing about mental states with small groups of 2-year-old children at nursery had a significant effect on toddlers’ theory of mind (ToM) and emotion understanding (EU). Participants were 68 children (M_age at pre-test: 29.9 months) who were assigned to either an experimental or a control condition. Measures of verbal ability, ToM and EU were administered at pre-test, post-test and follow-up stages. Over a one-month intervention, all children were read a series of brief illustrated stories. After listening to the stories, the experimental group (n = 34) was involved in conversations on mental states, whereas the control group (n = 34) was engaged in conversation regarding the material entities and actions featured in the storybook. The experimental group significantly outperformed the control group on measures of both ToM and EU, independently of gains in verbal ability. Furthermore, these positive effects remained stable over time. We discuss the theoretical and practical implications of these findings.     

Patient‐focused research supported practices in an intensive family therapy unit

The aim of this study is to explain how families evaluate and describe the use of two measures, the session rating scale and the outcome rating scale, in order to monitor therapeutic work. This study is methodologically based on modifications of methodical hermeneutics and consensual qualitative research. The results confirm the feasibility of these scales although some difficulties were identified. The analysis of the family interviews identified four conversational processes: communicating, focusing, structuring and exploration. These arise through the application of the scales, indicating their usefulness as conversational tools. In general, it is suggested that all the measurements and tools applied can be seen as therapeutic tools that are especially useful for establishing conversations and strengthening collaboration between service users and therapists. This brings the practice of monitoring therapeutic work into close contact with postmodern‐oriented forms of therapy.     

Different answers to different audiences: effects of social context on the accuracy-informativeness trade-off

Research on conversational exchanges shows that people attempt to optimise their responses’ relevance when they definitely know the correct answer (e.g., “What time is it?”). However, such certainty is often unavailable while speakers may still be under social pressure to provide an answer. We investigated how social context influences the informativeness level when answering questions under uncertainty. In three experiments, participants answered difficult general-knowledge questions placed in different social contexts (formal vs. informal). Participants generated their answers, then they were presented with a given context, and decided on the number of alternative responses they wanted to provide (single, with one alternative vs. plural, with several alternatives) and whether the answer should be reported or withheld (report option). Participants reported more answers in the informal context. In the formal context, single answers were preferred, and they were more frequently reported. We conclude that social context influences the level of informativeness in a conversation, affecting achievable accuracy. Our results also show the joint influence of the confidence and the social context on willingness to share information.     

Gricean Belief Change

One of the standard principles of rationality guiding traditional accounts of belief change is the principle of minimal change: a reasoner's belief corpus should be modified in a minimal fashion when assimilating new information. This rationality principle has stood belief change in good stead. However, it does not deal properly with all belief change scenarios. We introduce a novel account of belief change motivated by one of Grice's maxims of conversational implicature: the reasoner's belief corpus is modified in a minimal fashion to assimilate exactly the new information. In this form of belief change, when the reasoner revises by new information p ∨ q their belief corpus is modified so that p∨q is believed but stronger propositions like p∧q are not, no matter what beliefs are in the reasoner's initial corpus. We term this conservative belief change since the revised belief corpus is a conservative extension of the original belief corpus given the new information.     

Rethinking our Maxims: Perceptual Salience and Practical Judgment in Kantian Ethics

Some contemporary Kantians have argued that one could not be virtuous without having internalized certain patterns of awareness that permit one to identify and respond reliably to moral reasons for action. I agree, but I argue that this insight requires unrecognized, farreaching, and thoroughly welcome changes in the traditional Kantian understanding of maxims and virtues. In particular, it implies that one's characteristic emotions and desires will partly determine one's maxims, and hence the praiseworthiness of one's actions. I try to show this by pointing out an instability in the Kantian understanding of maxims. On the one hand, maxims are thought of as consciously affirmed, subjective principles of action. On the other hand, Kantians claim that nothing counts as an action, nor as morally assessable, unless it has a maxim. One cannot take both thoughts seriously without implausibly constricting the range of behavior that counts as action, hence as morally assessable. This difficulty can be overcome, I suggest, by jettisoning the idea that maxims must be consciously affirmed, and by stressing the way in which maxims are grounded in the pruning and shaping of one's emotions and desires during socialization. This opens the door to a rich Kantian theory of virtue. It also raises questions about the scope and ground of our moral responsibility, which I address at the end of the paper.     

Effects of Right- and Left-Hemisphere Damage on Understanding Conversational Implicatures

Processing of implicatures was examined in 27 right-brain-damaged (RBD) and 31 left-brain-damaged (LBD) stroke patients with focal lesions using a new implicatures battery (IB) as part of an exploration of the neural basis and modularity of natural language pragmatics. Following Grice, we sampled implicatures of Quantity, Quality, Relation, and Manner. Verbal implicatures consisted of two-sentence conversational vignettes which are literally problematic. Nonverbal implicatures consisted mostly of famous paintings that are literally problematic (e.g., Magritte's "Le Domain d'Arnheim"). The patient has to identify and solve the problem. To compare with performance on the IB, patients also received a Hebrew adaptation of Gardner and Brownell's Right Hemisphere Communication Battery, a new test of basic speech acts (verbal and nonverbal assertions, questions, requests, and commands), a Hebrew version of the Western Aphasia Battery, and standardized neuropsychological tests. Both LBD and RBD patients were significantly impaired in implicature processing relative to age-matched normal controls. In general, both patient groups showed weak correlations of implicatures with extents of lesions in left perisylvian language area or its right-hemisphere (RH) homolog. However, performance of LBD and RBD patients on the IB revealed different patterns of correlations with other pragmatic, language, and nonlanguage tests. In LBD patients, there was a greater association between performance on verbal and nonverbal implicatures and between performance on implicatures and basic speech acts than in RBD patients. Given the different modes in which right-and left-hemisphere (LH) damage affect the processing of conversational implicatures, it remains to be discovered how the two hemispheres interact to process natural language pragmatics in the normal brain in real time.     

Speech act conditions as tools for reconstructing argumentative discourse

According to the pragma-dialectical approach to argumentation, for analysing argumentative discourse, a normative reconstruction is required which encompasses four kinds of transformations. It is explained in this paper how speech act conditions can play a part in carrying out such a reconstruction. It is argued that integrating Searlean insights concerning speech acts with Gricean insights concerning conversational maxims can provide us with the necessary tools. For this, the standard theory of speech acts has to be amended in several respects and the conversational maxims have to be translated into speech act conditions. Making use of the rules for communication thus arrived at, and starting from the distribution of speech acts in a critical discussion as specified in the pragma-dialectical model, it is then demonstrated how indirect speech acts are to be transformed when reconstructing argumentative discourse.
