Reclaiming Communication

This article focuses on the history of the ecumenical discussion on communication, as reflected in the assemblies of the World Council of Churches (WCC). It examines, in particular, the communication statements that emerged from the WCC assemblies in Uppsala in 1968 and in Vancouver in 1983, as well as the more tentative moves at the Harare assembly of 1998 to develop an understanding of communication as an integral part of an “ecumenical space.” The article goes on to argue that the changing perspectives manifested at these assemblies, each 15 years apart, were linked to changing paradigms of social and theological reflection that were themselves the product of economic and political transformation. Finally, the article considers how the insights gained can be brought to bear on the challenges presented by digital transformation.     

Canine responses to familiar and unfamiliar humans

Dogs were observed during controlled approaches by their owners and by strangers. Significant differences between the dogs' responses to their owners and their responses to strangers were found. These results supported the popular belief that dogs respond differently to different persons, and not merely to different situations in which persons are usually encountered.     

Sex differences in aggressive behavior in a marsupial,the gray short-tailed opossum (Monodelphis domestica)

In male and female gray short-tailed opossums (Monodelphis domestica), same-sex interactions were characterized by high levels of threat behavior (open-mouth postures and screeching vocalizations). Actual fighting behavior (biting, locking, and tumbling) was seen almost exclusively in male-male interactions. In male-female interactions, females showed high levels of threat behavior and males showed little aggressive behavior of any kind. Clicking vocalizations, submissive behavior in marsupials, were displayed almost exclusively by males. These findings are discussed with respect to the uses of auditory and olfactory communication in marsupials.     

Infants’ intentionally communicative vocalizations elicit responses from caregivers and are the best predictors of the transition to language: A longitudinal investigation of infants’ vocalizations,gestures and word production

What aspects of infants’ prelinguistic communication are most valuable for learning to speak, and why? We test whether early vocalizations and gestures drive the transition to word use because, in addition to indicating motoric readiness, they (a) are early instances of intentional communication and (b) elicit verbal responses from caregivers. In study 1, 11 month olds (N = 134) were observed to coordinate vocalizations and gestures with gaze to their caregiver's face at above chance rates, indicating that they are plausibly intentionally communicative. Study 2 tested whether those infant communicative acts that were gaze‐coordinated best predicted later expressive vocabulary. We report a novel procedure for predicting vocabulary via multi‐model inference over a comprehensive set of infant behaviours produced at 11 and 12 months (n = 58). This makes it possible to establish the relative predictive value of different behaviours that are hierarchically organized by level of granularity. Gaze‐coordinated vocalizations were the most valuable predictors of expressive vocabulary size up to 24 months. Study 3 established that caregivers were more likely to respond to gaze‐coordinated behaviours. Moreover, the dyadic combination of infant gaze‐coordinated vocalization and caregiver response was by far the best predictor of later vocabulary size. We conclude that practice with prelinguistic intentional communication facilitates the leap to symbol use. Learning is optimized when caregivers respond to intentional vocalizations with appropriate language.     

Expressing embarrassment (or not): Which effects on produced impression on others and on attributed social value?

IntroductionEmbarrassment is a negative but prosocial emotion, which often arises from the transgression of a social norm. Its expression thus plays a crucial role in the social perception.ObjectiveThe aim of this paper is to document this role during both ordinary and extra-ordinary situations (i.e., with stakes).MethodUsing scenarios’ method, 27 participants and 100 recruiters evaluated persons expressing embarrassment or not.ResultsStudy 1 showed that during ordinary situations, nonverbal expression of embarrassment led to make a good impression by signalling desire of appeasement and prosociality. In contrast, Study 2 revealed that during a job interview, verbal expression of embarrassment through defensive tactics was rather negatively perceived.ConclusionThe manipulation of emotions as emotive communication tools will be discussed.     

External HMI for self-driving vehicles: Which information shall be displayed?

The objective of this study was to investigate pedestrians’ informational needs towards self-driving vehicles (SDVs). Previous research has shown that external human-machine interfaces (eHMIs) compensate for pedestrian-driver communication when SDVs are integrated into traffic. However, detailed insights on which information the eHMI shall provide lack so far. In a mixed design study, N = 59 participants encountered a simulated driverless vehicle in different traffic scenarios (a. unsignalized intersection vs. b. parking lot; between-subject factor). We investigated the effect of no eHMI (baseline) vs. eHMIs displaying the automated driving system (ADS) status, and informing subsequently about its perception of the pedestrian and/or its intent for the next maneuver ((1) no eHMI, (2) status eHMI, (3) status + perception eHMI, (4) status + intent eHMI, (5) status + perception + intent eHMI; within-subject factor). A mixed-methods design was used to explore participants’ subjective feelings, traffic behavior, and underlying attitudes. The findings reveal that any eHMI contributes to a more positive feeling towards SDVs compared to the baseline condition without eHMI, consistent among traffic scenarios: participants felt significantly safer, reflected greater trust and user experience ratings, and perceived the SDV as more intelligent and transparent. The status indicator mainly drives these beneficial effects on subjective measures. Participants reported that the status information explains the absence of a driver steering the vehicle. Compared to the status eHMI, the status + perception eHMI reflects no further benefit regarding subjective feelings and even has a negative impact on traffic flow. Moreover, participants regarded the additional information on the vehicle’s perception as an obvious gimmick. On the contrary, the status + intent eHMI increases user experience, perceived intelligence, and transparency for pedestrians more than the mere status eHMI. Participants reported that additionally informing about the vehicle’s intent adds a further sense of safety. The present study failed to show any improvements in traffic flow but found evidence for individual crossing and clearing strategies among pedestrians. This work can inform the future design of eHMIs.     

Effects of response preference on resistance to change

Treatments based on differential reinforcement of alternative behavior, such as functional communication training, are widely used. Research regarding the maintenance of related treatment effects is limited. Nevin and Wacker (2013) provided a conceptual framework, rooted in behavioral momentum theory, for the study of treatment maintenance that addressed two components: (a) reemergence of problem behavior, and (b) continued expression of appropriate behavior. In the few studies on this topic, focus has been on variables impacting the reemergence of problem behavior, with fewer studies evaluating the persistence of appropriate behavior. Given the findings from applied research related to functional communication training, variables related to response topography, such as response preference, may impact this aspect of maintenance. In the current study, the impact of response preference on persistence was evaluated in the context of functional communication training for individuals who did not exhibit problem behavior (Experiment 1) and for individuals with a history of reinforcement for problem behavior (Experiment 2). High‐preferred mands were more persistent than low‐preferred mands. These findings suggest that response related variables, such as response preference, impact response persistence and further suggest that response related variables should be considered when developing interventions such as functional communication training.     

Who speaks? Who looks? Who feels? Point of view in autobiographical narratives1

In this paper, the author aims to substantiate Freud's claim that neurotic illness creates gaps in autobiographical narratives in terms of the narrator's stating and inducing perspectives. He sketches out the role of narrative perspective and the joint taking of a shared perspective by analyst and patient in psychoanalytic therapy. He introduces four ways of representing perspectives in narratives. Three degrees of narrative distortion are exemplifi ed by three excerpts from life narratives and explored in terms of narrative perspective representation. The most comprehensive perspective representation is achieved in the fi rst example by explicitly stating the present perspective of the narrator as well as the past perspective of the story's protagonist by use of mental verbs. In the second narrative, exclusive use of linguistic forms for inducing the protagonist's perspective both overwhelms the narrator and gives the listener an incomplete picture of what happened. Inconsistent motives, denial of responsibility and omission of detail render the third narrative even more diffi cult to follow. The author discusses the clinical signifi cance of this exploratory analysis of perspectives in narratives in terms of claiming responsibility for one's past action and of level of defence mechanisms, and by highlighting the emotional impact on listeners, which the author suggests is the stronger the more perspectives are left out. He discusses analogies to countertransference. The analysis of narrative perspectives offers an approach for systematic research in psychoanalytic practice.     

高中生的亲子沟通质量对情绪性刺激注意偏向的影响

为了探讨高中生亲子沟通质量对情绪性刺激注意偏向的影响,实验一采用亲子沟通量表,筛选出亲子沟通高分组和低分组,两组被试参加点探测任务,要求被试迅速判断情绪性图片出现后呈现的圆点的位置。实验为2（组别：高亲子沟通组、低亲子沟通组）×2（情绪类型：负性和正性）×2（探测点位置一致性：一致、不一致）的混合实验设计。结果发现,负性和正性刺激的不一致条件反应时均显著短于一致条件的反应时。实验二采用事件相关电位（ERP）记录了情绪性图片诱发的信号反应。结果发现,亲子沟通高分组对负性刺激所诱发的注意指向和集中（P2成分）及选择和巩固（P3成分）显著高于低分组。以上结果表明,亲子沟通较好,在注意早期定向和选择中会对负性情绪刺激产生注意偏向。亲子沟通较差,则对情绪性的刺激没有明显的偏向性,类似于“漠不关心”的状态。
