There is considerable interest in determining whether high-quality American Sign Language videos can be used as an accommodation in tests of mathematics at both K-12 and postsecondary levels; and in learning more about the usability (e.g., comprehensibility) of ASL videos with two different types of signers - avatar (animated figure) and human. The researchers describe the results of administering each of nine pre-college mathematics items in both avatar and human versions to each of 31 Deaf participants with high school and post-high school backgrounds...

Purpose The purpose of this study was to evaluate the perceptions that certified diabetes educators (CDEs), of diverse health professions, have of a culturally appropriate e-health intervention that used avatar-based technology. Methods Cross-sectional, survey-based design using quantitative and qualitative paradigms. A logic model framed the study, which centered on the broad and general concepts leading to study outcomes. In total, 198 CDEs participated in the evaluation. Participants were mostly female and represented an age range of 26 to 76 years...

Upon a first encounter, individuals spontaneously associate faces with certain personality dimensions. Such first impressions can strongly impact judgments and decisions and may prove highly consequential. Researchers investigating the impact of facial information often rely on (a) real photographs that have been selected to vary on the dimension of interest, (b) morphed photographs, or (c) computer-generated faces (avatars). All three approaches have distinct advantages. Here we present the Basel Face Database, which combines these advantages...

A key predictor of whether or not an individual who hears voices (auditory verbal hallucinations; AVH) meets criteria for a psychiatric diagnosis is the level of negative content of the voices (e.g., threats, criticism, abuse). Yet the factors that contribute to negative voice-content are still not well understood. This study aimed to test the hypotheses that levels of childhood adversity would predict levels of negative voice-content, and that negative voice-content would partially mediate a relation between childhood adversity and voice-related distress...

Participants' performance differs when conducting a task in the presence of a secondary individual, moreover the opinion the participant has of this individual also plays a role. Using EEG, we investigated how previous interactions with, and evaluations of, an avatar in virtual reality subsequently influenced attentional allocation to the face of that avatar. We focused on changes in the alpha activity as an index of attentional allocation. We found that the onset of an avatar's face whom the participant had developed a rapport with induced greater alpha suppression...

BACKGROUND: Presently, ∼85 serially transplantable human prostate cancer xenografts spanning the phenotypic, epigenetic, and genetic heterogeneity seen clinically are available in a variety of laboratories throughout the world. If distributed to the prostate cancer research community, these can provide an experimental platform for resolving the specificity versus generalizability of basic cancer biology principles (eg, credentialing of therapeutic molecular targets) and for validating translational approaches for prevention, diagnosis, and therapy...

Julia Marshall, Anton Gollwitzer, Laurie R Santos
Considerable debate has focused on whether adults possess an implicit system for representing others' mental states. Some argue that people automatically represent the perspective of others using evidence from altercentric interference-cases in which another agent's perspective affects the speed with which one can report one's own perspective. Others have argued that altercentric interference is not always specific to social stimuli and thus may represent a simpler process such as submentalizing. To distinguish between these positions, Study 1 developed a novel measure of altercentric interference-a "sandbox" measure-that allowed us to more sensitively assess altercentric interference across social and non-social conditions...

OBJECTIVE: The PAL project develops a conversational agent with a physical (robot) and virtual (avatar) embodiment to support diabetes self-management of children ubiquitously. This paper assesses 1) the effect of perceived similarity between robot and avatar on children's' friendship towards the avatar, and 2) the effect of this friendship on usability of a self-management application containing the avatar (a) and children's motivation to play with it (b). METHODS: During a four-day diabetes camp in the Netherlands, 21 children participated in interactions with both agent embodiments...

This article reports the impact of the degree of personalization and individualization of users' avatars as well as the impact of the degree of immersion on typical psychophysical factors in embodied Virtual Environments. We investigated if and how virtual body ownership (including agency), presence, and emotional response are influenced depending on the specific look of users' avatars, which varied between (1) a generic hand-modeled version, (2) a generic scanned version, and (3) an individualized scanned version...

The underrepresentation of women in technical and STEM fields is a well-known problem, and stereotype threatening situations have been linked to the inability to recruit and retain women into these fields. Virtual reality enables the unique ability to perform body-swap illusions, and research has shown that these illusions can change participant behavior. Characteristically people take on the traits of the avatar they are embodying. We hypothesized that female participants embodying male avatars when a stereotype threat was made salient would demonstrate stereotype lift...

Most existing locomotion devices that represent the sensation of walking target a user who is actually performing a walking motion. Here, we attempted to represent the walking sensation, especially a kinesthetic sensation and advancing feeling (the sense of moving forward) while the user remains seated. To represent the walking sensation using a relatively simple device, we focused on the force rendering and its evaluation of the longitudinal friction force applied on the sole during walking. Based on the measurement of the friction force applied on the sole during actual walking, we developed a novel friction force display that can present the friction force without the influence of body weight...

With the broad range of motion capture devices available on the market, it is now commonplace to directly control the limb movement of an avatar during immersion in a virtual environment. Here, we study how the subjective experience of embodying a full-body controlled avatar is influenced by motor alteration and self-contact mismatches. Self-contact is in particular a strong source of passive haptic feedback and we assume it to bring a clear benefit in terms of embodiment. For evaluating this hypothesis, we experimentally manipulate self-contacts and the virtual hand displacement relatively to the body...

Dennis Küster
Small pupils elicit empathic socioemotional responses comparable to those found for emotional tears. This might be understood in an evolutionary context. Intense emotional tearing increases tear film volume and disturbs tear layer uniformity, resulting in blurry vision. A constriction of the pupils may help to mitigate this handicap, which in turn may have resulted in a perceptual association of both signals. However, direct empirical evidence for a role of pupil size in tearful emotional crying is still lacking...

The history of the mental hospital in Delhi is a fascinating story. Set up in colonial times, the asylum in Delhi seems to reflect the tumultuous and chaotic history of the city itself. It was perhaps established in the early 19th century, and functions till 1857, when it is ransacked in the Mutiny. It is subsequently merged with the asylum at Lahore in 1861, set up again, and incredibly, closed again at the turn of the century. Subject to the whims of administrators and policy makers, the asylum then ceases to exist till the 1960s when a new avatar appears...

For inhibitor design, as in most research, the best system is question dependent. We suggest structurally defined allostery to design specific inhibitors that target regions beyond active sites. We choose systems allowing efficient quality structures with conformational changes as optimal for structure-based design to optimize inhibitors. We maintain that evolutionarily related targets logically provide molecular avatars, where this Sanskrit term for descent includes ideas of functional relationships and of being a physical embodiment of the target's essential features without requiring high sequence identity...

This study assessed the subjective experience of participating in a clinical trial, specifically positive and negative experiences and the experience of audio recording assessment sessions. The study was cross-sectional from a single blinded randomised controlled trial. Forty participants with a primary diagnosis of non-organic psychosis completed baseline and 12-week follow-up questionnaires assessing their experiences. Participants rated research interviews as moderately helpful in facilitating their therapy and talking to the interviewer as moderately helpful at baseline and 12-week follow-up...

In colorectal carcinoma (CRC) patients, distant metastatic disease is present at initial diagnosis in nearly 25% of them. The majority of patients with metastatic CRC have incurable disease; therefore, new therapies are needed. Agents derived from medicinal plants have already demonstrated therapeutic activities in human cancer cells. Antartina™ is an antitumor agent isolated from Deschampsia antarctica Desv. This study aimed to evaluate the antitumor properties of Antartina™ in CRC models. We used human and murine CRC cell lines for investigating proliferation, apoptosis and cell cycle effects of Antartina™ therapy in vitro...

Classically, body ownership illusions are triggered by cross-modal synchronous stimulations, and hampered by multisensory inconsistencies. Nonetheless, the boundaries of such illusions have been proven to be highly plastic. In this immersive virtual reality study, we explored whether it is possible to induce a sense of body ownership over a virtual body part during visuomotor inconsistencies, with or without the aid of concomitant visuo-tactile stimulations. From a first-person perspective, participants watched a virtual tube moving or an avatar's arm moving, with or without concomitant synchronous visuo-tactile stimulations on their hand...
