Social touch to build trust:A systematic review of technology-mediated and unmediated interactions
No full textAvatars and social robots offer new opportunities for communication and raise questions about how trust is built and maintained in hybrid social interactions. We wonder what kind of trust people build with these technologies, especially where they are no longer simply tools but rather partners in interactions and affective exchanges involving vulnerability and reciprocity. Following the PRISMA guidelines, we conducted a systematic review on how trust in humans and technology can be shaped by social touch, which is the bodily contact occurring between two or more parties that express and share affective signals. Based on the n = 15 papers that meet the inclusion criteria, the evidence on the power of social touch to facilitate trust appears limited. Especially in the realm of technology-mediated interactions, mixed and inconclusive results emerge in different social contexts. Individual differences and neurophysiological correlates that could shed light on the effects between touch and trust are rarely investigated. Our positive proposal is that future studies should overcome the divisive conceptualisation of trustor and trustee, and rather explore the phenomenon of trust as a two-person bridge built in synergy between the parties. Outlining some key directions for future research, we discuss the extant solutions and applications of technology-mediated social touch, delving into the sensory and contextual factors that make it similar but different to unmediated social touch. We propose that if social touch were to be effective in promoting trust in specific technologies, this would have important consequences on various application domains such as telecommunication, healthcare, and education

Swelling and shrinking kinetics of a lamellar gel phase
No full textWe investigate the swelling and shrinking of L lamellar gel phases composed of surfactant and fatty alcohol after contact with aqueous poly(ethyleneglycol) solutions. The height change Δh(t) is diffusionlike with a swelling coefficient S: Δh=S√t. On increasing polymer concentration, we observe sequentially slower swelling, absence of swelling, and finally shrinking of the lamellar phase. This behavior is summarized in a nonequilibrium diagram and the composition dependence of S quantitatively described by a generic model. We find a diffusion coefficient, the only free parameter, consistent with previous measurements
Reciprocity and alignment: quantifying coupling in dynamic interactions
No full textRecent accounts of social cognition focus on how we do things together suggesting that becoming aligned relies on a reciprocal exchange of information. The next step is to develop richer computational methods that quantify the degree of coupling and describe the nature of the information exchange. We put forward a definition of coupling comparing it to related terminology and detail available computational methods and the level of organisation to which they pertain, presenting them as a hierarchy from weakest to richest forms of coupling. The rationale is that a temporally coherent link between two dynamical systems at the lowest level of organisation sustains mutual adaptation and alignment at the highest level. Postulating that when we do things together, we do so dynamically over time, we argue that to determine and measure instances of true reciprocity in social exchanges is key. Along with this computationally rich definition of coupling, we present challenges for the field to be tackled by a diverse community working towards a dynamic account of social cognition

Voice over: Audio-visual congruency and content recall in the gallery setting
No full textExperimental research has shown that pairs of stimuli which are congruent and assumed to 'go together' are recalled more effectively than an item presented in isolation. Will this multisensory memory benefit occur when stimuli are richer and longer, in an ecological setting? In the present study, we focused on an everyday situation of audio-visual learning and manipulated the relationship between audio guide tracks and viewed portraits in the galleries of the Tate Britain. By varying the gender and narrative style of the voice-over, we examined how the perceived congruency and assumed unity of the audio guide track with painted portraits affected subsequent recall. We show that tracks perceived as best matching the viewed portraits led to greater recall of both sensory and linguistic content. We provide the first evidence that manipulating crossmodal congruence and unity assumptions can effectively impact memory in a multisensory ecological setting, even in the absence of precise temporal alignment between sensory cues
Coordinating attention requires coordinated senses
No full textFrom playing basketball to ordering at a food counter, we frequently and effortlessly coordinate our attention with others towards a common focus: we look at the ball, or point at a piece of cake. This non-verbal coordination of attention plays a fundamental role in our social lives: it ensures that we refer to the same object, develop a shared language, understand each other’s mental states, and coordinate our actions. Models of joint attention generally attribute this accomplishment to gaze coordination. But are visual attentional mechanisms sufficient to achieve joint attention, in all cases? Besides cases where visual information is missing, we show how combining it with other senses can be helpful, and even necessary to certain uses of joint attention. We explain the two ways in which non-visual cues contribute to joint attention: either as enhancers, when they complement gaze and pointing gestures in order to coordinate joint attention on visible objects, or as modality pointers, when joint attention needs to be shifted away from the whole object to one of its properties, say weight or texture. This multisensory approach to joint attention has important implications for social robotics, clinical diagnostics, pedagogy and theoretical debates on the construction of a shared world
