Disconnections of African American Public Housing Residents: Connections to Physical Activity, Dietary Habits and Obesity

African American (AA) and low SES populations report poor health behaviors and outcomes. This study aimed to increase understanding of barriers to participating in healthful behaviors and programs in AA residents of public housing. Twenty two apparently healthy, AA residents (50% female, M = 43.9 years) completed in depth interviews, which were taped, transcribed and analyzed using a constant comparison approach. Residents demonstrated some awareness of health recommendations, but described limited adherence. Physical activity for recreation was reported as primarily for youth, with adults engaging in limited physical activity (primarily incidental to other activities). Barriers reported by residents were both personal and environmental. Few residents were aware of local neighborhood opportunities for physical activity or healthful eating. Future efforts should focus on increasing understanding of health promoting behaviors and awareness and efficacy of residents to connect with the resources of their surrounding communities.     

The need for public policies to promote healthier food consumption: A comment on Wansink and Chandon (2014)

Current approaches to addressing obesity have fallen short. This is largely due to the many environmental forces that undermine people's self-regulatory capacity to be personally responsible for their food choices. Novel insights from the social sciences are needed to inform voluntary, health-promoting actions by companies, institutions, and citizens as well as the design of public health policies. Voluntary interventions that rely on nudges should complement traditional public health strategies such as taxation and restriction of child-targeted marketing in schools. In this commentary, we discuss four food policy issues that would benefit from consumer psychology research: (a) the restriction of food marketing to children, (b) provision of nutrition information through food labels, (c) improving school food environments, and (d) placing limits on portion sizes. Identifying effective solutions for obesity will require approaches that integrate psychological, public health, and legal perspectives and methods.     

Meaning,grounding, and the construction of social reality

Culture has become a critical concept for social psychology over the past quarter of a century. Yet, cultural dynamics, the process and mechanism of formation, maintenance, and transformation of culture, has begun to be investigated only recently. This article reports the current state of play of a research program that takes cultural dynamics as its central question. In this approach, humans are construed as meaning making animals that create, recreate, and exchange information, and turn it into a meaningful basis for action. The locus of meaning making and remaking is an everyday joint activity. The grounding model of cultural transmission describes how cultural information is deliberately or inadvertently transmitted in a joint activity. As we go about our business of living our daily lives, we ground information to our common ground, and construct a social reality that is mutually meaningful and yet only local. If locally grounded information is further generalized to a large collective and disseminated through social networks, repeated and iterative activations of the grounding process maintain the social reality of the collective that we take for granted. Implications of the grounding model of cultural transmission and future research directions are discussed.     

Social and political perspectives on the psychotherapy and counselling profession: Returning caravelles

The counselling and psychotherapy profession is changing. For the first time in its history, it has begun to receive substantial Government funding in the UK and it also has to contend with the principles of evidence-based practice and the policies of the New Public Management systems in many countries. This paper argues that such recent developments present challenges to the profession’s historical apolitical standpoint. More importantly, it argues that the present social and political climate offers many opportunities such as the possibility of learning from psychosocial practices in other countries. The paper will look, in particular, at what can be learned from Latin America and India where mental health care and psychological therapy have adopted grassroots involvement, health-focused approaches and innovatory therapeutic methods.     

Two-step communication for the interaction between automated vehicles and pedestrians

An important challenge of automated vehicles (AV) will be the cooperative interaction with surrounding road users such as pedestrians. One solution to compensate for the missing driver-pedestrian interaction might be explicit communication via external human machine interfaces (eHMIs). Additionally, implicit communication such as a vehicle pitch motion might support AVs when interacting with pedestrians. While previous work explored various explicit and implicit communication cues, these concepts communicated the intention of the AV at one single time point. Currently, empirical findings on two-step communication lack so far. In this study, we empirically test the effect of a two-step AV communication that uses an implicit cue at a long distance and subsequently provides an implicit or explicit cues at a short distance. We compared its efficiency to single-step communication concepts providing implicit or explicit cues at the shorter distance only. To explore whether the right communication cue is used at the right distance, we analyzed pedestrians’ fixations while approaching an AV using an eye tracking device.We conducted a virtual reality study (N = 30) with AV communication concept that provided an active pitch motion or an eHMI and compared them with a two-step AV communication concept that provided an additional active pitch motion at a long distance when approaching the pedestrian. Furthermore, we recorded pedestrians’ fixation behavior while the AV approached.Consistently to previous work, single-step AV communication showed a beneficial effect on crossing behavior. Pedestrians initiated their crossing earlier while approaching an AV with an active pitch motion or an eHMI compared to the baseline condition. While active pitch motion reduced subjective safety feeling, eHMI increased it. However, the two-step communication concept did not further improve pedestrians’ crossing initiation times and their safety feeling. The pattern of fixation behavior differed as a function of AV distance. When the approaching AV was far away, pedestrians exclusively looked at the environment. During the approach, pedestrians gradually fixated the bumper and the hood and only then the windshield of the AV. Hence, it seems to be useful to present an AV intent communication at a certain distance from the pedestrian. These findings posit the importance of considering pedestrians’ fixation behavior when developing communication concepts between AVs and pedestrians.     

User gesticulation inside an automated vehicle with external communication can cause confusion in pedestrians and a lower willingness to cross

Automated vehicles are expected to require some form of communication (e.g., via LED strip or display) with vulnerable road users such as pedestrians. However, the passenger inside the automated vehicle could perform gestures or motions which could potentially be interpreted by the pedestrian as contradictory to the outside communication of the car. To explore this conflict, we conducted an online experiment (N = 59) with different message types (no message, intention, command), gestures (no gesture, wave, stop), and user positions (driver, co-driver) and measured the pedestrian’s confidence in crossing. Our results show that certain combinations (e.g., car indicates cross while the user in the driver seat gestures stop) confused the pedestrian, resulting in significantly lower confidence to cross. We further show that designing intention-based external communication led to less confusion and a significantly higher intention to cross.     

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.
