Active vehicle pitch motion for communication in automated driving

The number of automated vehicles (AVs) is expected to successively increase in the near future. This development has a considerable impact on the informal communication between AVs and pedestrians. Informal communication with the driver will become obsolete during the interaction with AVs. Literature suggests that external human machine interfaces (eHMIs) might substitute the communication between drivers and pedestrians. In the study, we additionally test a recently discussed type of communication in terms of artificial vehicle motion, namely active pitch motion, as an informal communication cue for AVs.N = 54 participants approached AVs in a virtual inner-city traffic environment. We explored the effect of three communication concepts: an artificial vehicle motion, namely active pitch motion, eHMI and the combination of both. Moreover, vehicle types (sports car, limousine, SUV) were varied. A mixed-method approach was applied to investigate the participantś crossing behavior and subjective safety feeling. Furthermore, eye movement parameters were recorded as indicators for mental workload.The results revealed that any communication concept drove beneficial effects on the crossing behavior. The participants crossed the road earlier when an active pitch motion was present, as this was interpreted as a stronger braking. Further, the eHMI and a combination of eHMI and active pitch motion had a positive effect on the crossing behavior. The active pitch motion showed no effect on the subjective safety feeling, while eHMI and the combination enhanced the pedestrianś safety feeling while crossing. The use of communication resulted in less mental workload, as evidenced by eye-tracking parameters. Variations of vehicle types did not result in significant main effects but revealed interactions between parameters. The active pitch motion revealed no learning. In contrast, it took participants several trials for the eHMI and the combination condition to affect their crossing behavior. To sum up, this study indicates that communication between AVs and pedestrians can benefit from the consideration of vehicle motion.     

Social eye gaze modulates processing of speech and co-speech gesture

In human face-to-face communication, language comprehension is a multi-modal, situated activity. However, little is known about how we combine information from different modalities during comprehension, and how perceived communicative intentions, often signaled through visual signals, influence this process. We explored this question by simulating a multi-party communication context in which a speaker alternated her gaze between two recipients. Participants viewed speech-only or speech + gesture object-related messages when being addressed (direct gaze) or unaddressed (gaze averted to other participant). They were then asked to choose which of two object images matched the speaker’s preceding message. Unaddressed recipients responded significantly more slowly than addressees for speech-only utterances. However, perceiving the same speech accompanied by gestures sped unaddressed recipients up to a level identical to that of addressees. That is, when unaddressed recipients’ speech processing suffers, gestures can enhance the comprehension of a speaker’s message. We discuss our findings with respect to two hypotheses attempting to account for how social eye gaze may modulate multi-modal language comprehension.     

ANALYTIC MIND USE AND INTERPSYCHIC COMMUNICATION: DRIVING FORCE IN ANALYTIC TECHNIQUE,PATHWAY TO UNCONSCIOUS MENTAL LIFE

Developed from established psychoanalytic knowledge among different psychoanalytic cultures concerning unconscious interpsychic communication, analysts' use of their receptive mental experience—their analytic mind use, including the somatic, unconscious, and less accessible derivatives—represents a significant investigative road to patients' unconscious mental life, particularly with poorly symbolized mental states. The author expands upon this tradition, exploring what happens when patients unconsciously experience and identify with the analyst's psychic functioning. The technical implications of the analyst's “instrument” are described, including the analyst's ego regression, creation of inner space, taking mind as object, bearing uncertainty and intense affect, and self‐analysis. Brief case vignettes illustrate the structure and obstacles to this work.     

First symbols in a girl with Down syndrome: A longitudinal study from 12 to 18 months

Symbolic uses of objects originate in communicative and triadic contexts (adult–child-object). In this longitudinal study we explore the emergence and development of the first symbolic uses in triadic interaction contexts in a girl with Down syndrome between 12 and 18-months of age. We conducted five sessions of video recording, at 12, 13½, 15, 16½, and 18 months chronological age. At each session we videotaped the girl and her mother interacting with different objects. Data were coded in semiotic categories used in previous studies (Rodríguez & Moro, 1999) and a microgenetic analysis was conducted for each session. The first symbolic uses by the girl appeared at 13½ months. Symbols were of different types and levels of complexity, and the adult had an important role in facilitating the production of these symbols.     

Collaborative mother–toddler communication and theory of mind development at age 4

Focusing on social pragmatics, this longitudinal study investigated the contribution of mother–toddler collaborative communication to theory of mind (ToM) development at age 4. At age 2½, 78 toddlers (42 boys) and their mothers were observed during pretend play. At age 4, children were tested using 4 false belief understanding tasks. Both mothers and toddlers engaged in more collaborative (inform, guide/request, and support/confirm) than non-collaborative communication acts. Other-focused collaborative acts of support/confirm by mothers and toddlers predicted children's false belief understanding, even after controlling for 5 covariates. In addition, as active agents in their own ToM development, the contribution of toddlers' collaborative acts to false belief understanding was independent of their mother's. Finally, the way toddlers and their mothers co-constructed their communication mattered. Only when toddlers engaged in high levels of collaborative acts, the mothers' high levels of collaborative acts demonstrated a positive effect on children's ToM development. The applied implications of these findings are discussed.     

医学影像学见习应用PACS教学法与传统读片教学法的对比研究

将中南大学湘雅医学院2010级临床医学五年制197名学生随机分成两组,在医学影像学见习教学过程中分别应用影像存储及传输系统（PACS）教学法（98人）及传统读片教学法（99人）,学期结束时对两组学生考试成绩进行分析,并对PACS组学生进行问卷调查及结果分析.统计数据显示,PACS组学生读片测验及卷面考试中,病例分析题成绩显著高于传统读片组,问卷调查显示PACS组学生大多数认可该教学方法.因此,应用PACS教学有助于提高学生的临床分析能力及主动学习的能力,是学生欢迎的教学方式.但对医学影像学基本知识的传授,应用PACS法较传统读片法并无明显优势.     

Attachment and Mother-Child Communication in Adjustment to the Death of a Father Among Cambodian Adolescents

This study examined quality of attachment to the mother and child-mother communication in adolescents' adjustment to the death of a father. Forty-eight Cambodian adolescents whose father had died within the previous 3 years completed a set of measures that included attachment, communication, grief, and self-esteem. Results showed that quality of attachment to the mother and whether the adolescent communicated with the mother about the father and found this to be helpful were positively related to adaptive grief and self-esteem. Moreover, support was shown for an indirect effect of quality of attachment to the mother on adaptive grief as mediated by communication. Implications of the findings for quality of attachment in adjustment to bereavement in a non-Western cultural context are discussed.     

‘You have to treat the person,not the mouth only’: UK dentists’ perceptions of communication in patient consultations

Effective communication between patients and health professionals is a key component of patient-centred care. Although there is a large body of literature focusing on doctor-patient communication, there has been limited research related to dentist-patient communication, especially presented from the dentists’ perspective. The aim of our study was to explore UK dentists’ perceptions of communication in their consultations, and the factors they perceive may influence this. We conducted semi-structured interviews with eight dentists in UK dental NHS practices. Thematic analysis revealed three themes (‘Treating the whole person’, ‘Barriers to patient-centred communication’ and ‘Mutuality of communication’), which reflected the dentists’ perceptions of their own communication during consultations, the patients’ interaction skills, attitudes (and characteristics that may affect them), and external factors, such as time constraints, that can influence dentist-patients’ encounters. These in-depth accounts are valuable, in that we see what dentists perceive is important, obstructive and facilitative. They report using a patient-centred approach in their everyday dental practice; however this is often difficult due to factors such as time constraints. Although they emphasized that the patient has an active role to play in the communication process, it may be the case that they also need to play their part in facilitating this.     

‘Hope givers’? A scoping review of new media and mental health in 27 Australian Christian organisations

This article explains a range of conceptual and methodological innovations in the use of new media for the clinical practice and public communication of mental health. Building on two current contexts – the emerging research area of new media and mental health, and major reform of the mental health system in Australia – this article presents a scoping review of the online communication of Christian organisations that offer mental health care in Australia. This article compares the websites of 27 Australian Christian mental health organisations, analysing these organisations’ configurations of mainstream and religious modalities of mental health care, their discursive and visual communication strategies, as well as their use of social media platforms.
