Immersive collaborative virtual environments (CVEs) allow us to interact with geographically distant others while experiencing social presence to a degree that goes far beyond text chatting or teleconferencing. Moreover, these environments provide this high level of realism within social contexts that are impossible in the physical world. Given these facts, CVEs provide behavioral researchers with an ideal platform to study social interaction both within and between geographically and culturally distinct communities. The study reported here leveraged these two unique capabilities of CVEs within a persuasive context by: (1) placing people who are seated in physically distal places into the exact same virtual world, and (2) structuring virtual space to maximize persuasion. Specifically, we report data from a study in which pairs of participants listened to a speaker deliver a persuasive passage within the same digital immersive virtual room. The individual members of each pair were separated by hundreds of kilometers, located at two different college campuses. Within the CVE, we digitally transformed the placement of participants' seats in the virtual classroom. Participants in the front of the classroom were more persuaded by the speaker and had more positive impressions of the speaker. Patterns in both persuasion and memory differed between campuses. Together these findings speak to the utility of wide range CVEs to maximize persuasion and demonstrate the viability of using CVEs for inter-site research.

Abstract. In this work we present the development of a prototype, mobile mapping platform with modular design and architecture that can be suitably modified to address effectively both outdoors and indoors environments. Our system is built on the Robotics Operation System (ROS) and utilizes multiple sensors to capture images, pointclouds and 3D motion trajectories. These include synchronized cameras with wide angle lenses, a lidar sensor, a GPS/IMU unit and a tracking optical sensor. We report on the individual components of the platform, it’s architecture, the integration and the calibration of its components, the fusion of all recorded data and provide initial 3D reconstruction results. The processing algorithms are based on existing implementations of SLAM (Simultaneous Localisation and Mapping) methods combined with SfM (Structure-from-Motion) for optimal estimations of orientations and 3D pointclouds. The scope of this work, which is part of an ongoing H2020 program, is to digitize the physical world, collect relevant spatial data and make digital copies available to experts and public for covering a wide range of needs; remote access and viewing, process, design, use in VR etc.

Studies related to non-verbal communication in virtual space need to be explored as a result of changes in communication processes that largely rely on online interaction due to the COVID-19 pandemic. Undoubtedly, it has extended the scope of understanding an individual’s virtual presence and the effectiveness of non-verbal communication practices. In this study, non-verbal communication is explored in the process of online teaching and learning. Social Presence Theory has been used in understanding the practice of lecturers to establish relationships through their virtual presence and build closeness with students during online teaching and learning. In-depth interviews were conducted with a total of ten students of Universiti Utara Malaysia (UUM). This study has found that lecturers can establish relationships and closeness with students through non-verbal communication cues such as kinesic, proxemic, chronemic, and paralinguistic. Lecturers who practice effective non-verbal communication enable a positive effect on students in terms of motivation to learn, focus in learning sessions, create interest in understanding topics, and feel at ease in learning. However, the lecturers' non-verbal communication has had a negative effect if the lecturer is unable to build a good relationship especially in terms of chronemic and facial expressions cues. It will cause students to be unmotivated and experience emotional stress. In conclusion, non-verbal communication is still vital in the process of establishing a social presence and building relationships even online. The practice of non-verbal communication during the individual social presence in virtual space needs to be explored in other contexts such as in organisations.

This article presents a novel diagramming approach which employs aspects of Actor-Network Theory (ANT) in the creation of ANT Analysis Diagrams (AADs). ANT is a socio-material approach which allows for the consideration of both human and inanimate entities in a social context. AADs provide a novel method for the analytical investigation of social situations, thereby both operationalizing elements of ANT and generating a visualization of a domain. It is the process of creating an AAD which is crucial, focusing attention on the characteristics of the entities involved and the nature of the relationships between them, thereby supporting the analysis of qualitative social data. As this article illustrates, AADs can be usefully applied to a wide range of social contexts and across scales, from the individual person, to groups through to broad social concepts.

The economic behaviour, needs and preferences of people vary in the individual phases of their lives. The silver economy market is made up of consumers, employees or employers aged 50+. The share of this population is an important target group for entrepreneurs, brings a wide range of new products and services to businesses and has a significant role for the national economy as there is a change in the understanding of the ageing process from a threat towards economic opportunities. Although the ageing workforce and seniors in the Slovak Republic do not represent a strong demand for market goods yet, their economic potential may not be negligible. The rapid ageing of the Slovak population represents, among other things, an economic potential that can be exploited in favour of innovation and improvement. Despite not a high level of pensions, seniors have considerable purchasing power, which will generate an increasing demand for specific goods and services, which is an opportunity for the labour market. In this paper we try to describe selected areas in which the silver economy and the ageing population itself should be viewed as a challenge to new business opportunities. In particular, these include health service and health care, spa care, the pharmaceutical industry, tourism, the financial sector and, last but not least, construction industry. The silver economy will change the rules of market forces in existing sectors and create a wholly new industry at the intersection of demographic and technological changes with a high export potential.

ABSTRACT Adenovirus (AdV)-based vectors are popular experimental vaccine vectors, but despite their ability to induce strong immune responses, their application is impeded by widespread preexisting immunity against many AdV types that can impair or even abrogate the induction of transgene-specific immune responses. Therefore, the development of vectors based on AdV types with a low seroprevalence is important for effective AdV-based immunization in humans. We investigated the immunization efficacy of vectors based on AdV type 48 (Ad48) and Ad50 in the ovalbumin (ova) model as well as the Friend retrovirus (FV) model, which allows testing of the protective effect of vaccine-induced immunity. Using ova-encoding vectors, we found a significantly lower induction of ova-specific CD8+ T cells and antibody responses by Ad48- and Ad50-based vectors than by Ad5-based vectors. Similarly, we found a reduced induction of FV-specific CD8+ T cell responses in Ad48- and Ad50.Leader-Gag-immunized mice compared with that in Ad5-immunized mice; however, some of those mice were able to control the FV infection, and protection correlated with the level of neutralizing antibodies 10 days after FV challenge. Analyses of the AdV-specific antibodies and CD8+ T cells induced by the individual AdV types revealed a high level of cross-reactivity, and the efficacy of Ad48-based immunization was impaired in Ad5-preimmune mice. Our results show that the immunity induced by Ad48- and Ad50-based vectors is reduced compared to that induced by Ad5 and is sufficient to control FV infection in only some of the immunized mice. A high level of cross-reactivity suggests that AdV preimmunity must be considered even when applying rare AdV-based vectors. IMPORTANCE AdV-based vectors are important tools for the development of vaccines against a wide range of pathogens. While AdV vectors are generally considered safe and highly effective, their application can be severely impaired by preexisting immunity due to the widespread seroprevalence of some AdV types. The characterization of different AdV types with regard to immunogenicity and efficacy in challenge models is of great importance for the development of improved AdV-based vectors that allow for efficient immunization despite anti-AdV immunity. We show that the immunity induced by an Ad48-based vector is inferior to that induced by an Ad5-based vector but can still mediate the control of an FV infection in highly FV-susceptible mice. However, the efficacy of Ad48-based immunization was impaired in Ad5-preimmune mice. Importantly, we found cross-reactivity of both the humoral and cellular immune responses raised by the individual AdV types, suggesting that switching to a different AdV type may not be sufficient to circumvent preexisting anti-AdV immunity.

Attention And Perception

Cognitive scientists have paid very little attention to magic as a distinctly human activity capable of creating situations or events that are considered impossible because they violate expectations and conclude with the apparent transgression of well-established cognitive and natural laws. And even though magic techniques appeal to all known cognitive processes from sensing, attention and perception to memory and decision making, the relation between science and magic has so far been mostly unidirectional, with the primary goal of unraveling how magic works. Building up from the deconstruction of a classic magic trick, we provide here a cognitive foundation for the use of magic as a unique and largely untapped research tool to dissect cognitive processes in tasks arguably more natural than those usually exploited in artificial laboratory settings. Magicians can submerge every spectator into the precise experimental protocol they have previously designed, accounting with ease for both circumstantial and social contexts. Magicians do not base the success of their experiments in statistical measures that smear out the individual in favor of an average spectator that we know never exists in the real world. They target each and everyone in the audience and, often, with a complete accomplishment. Magicians deliver their cognitive manipulations in real-time, in tight closed-loop with the audience, and in a single trial (they cannot afford to repeat the trick if it fails). Magic has also an inherent and strong social component, merging the private cognitive processes of each spectator with the group dynamics. Finally, when combined with the wide range of precise measuring and wearable technologies available today, magic paves the way for a road not taken towards real-world cognitive science. We dare to speculate that some of the mysteries of how the brain works may be trapped in the split realities present in each magic effect.

Effective social interactions rely on humans’ ability to attune to others within social contexts. Recently, it has been proposed that the emergence of shared representations, as indexed by the Joint Simon effect (JSE), might result from interpersonal coordination (Malone et al., 2014). The present study aimed at examining interpersonal coordination in cooperative and competitive joint tasks. To this end, in two experiments we investigated response coordination, as reflected in instantaneous cross-correlation, when co-agents cooperate (Experiment 1) or compete against each other (Experiment 2). In both experiments, participants performed a go/no-go Simon task alone and together with another agent in two consecutive sessions. In line with previous studies, we found that social presence differently affected the JSE under cooperative and competitive instructions. Similarly, cooperation and competition were reflected in co-agents response coordination. For the cooperative session (Experiment 1), results showed higher percentage of interpersonal coordination for the joint condition, relative to when participants performed the task alone. No difference in the coordination of responses occurred between the individual and the joint conditions when co-agents were in competition (Experiment 2). Finally, results showed that interpersonal coordination between co-agents implies the emergence of the JSE. Taken together, our results suggest that shared representations seem to be a necessary, but not sufficient, condition for interpersonal coordination.
