The original relational triangulation perspective taking protocol (RT-PTP-M1; Guinther, ) was extended with a second training and testing module (RT-PTP-M2) showing contextual influence over derivation of another's "false beliefs" during an analog of the Sally-Anne test for Theory of Mind (Baron-Cohen, Leslie, & Frith, ; Wimmer & Perner, ) in verbally competent adults. Under the respective contextual control of experimental stimuli X2 and X3 , participants first learned through direct conditioning procedures that avatars A2 and A3 "behave the same way" towards target stimuli...

Previous research has shown that when people read vignettes about the infliction of harm upon an entity appearing to have no more than a liminal mind, their attributions of mind to that entity increased. Currently, we investigated if the presence of a facial wound enhanced the perception of mental capacities (experience and agency) in response to images of robotic and human-like avatars, compared with unharmed avatars. The results revealed that harmed versions of both robotic and human-like avatars were imbued with mind to a higher degree, irrespective of the baseline level of mind attributed to their unharmed counterparts...

BACKGROUND: Interprofessional education is a challenge given the current constraints of clinical education, which is bound by space, location, off-campus clinical rotations, and conflicting academic schedules. New approaches need to be developed if academic settings are to provide high-impact interprofessional education. METHOD: Virtual Interprofessional (VIP) Learning was developed as an innovative, online, asynchronous learning platform utilizing avatars that engages learners in interprofessional clinical learning opportunities across disciplines and settings...

BACKGROUND: Using patient-derived xenografts (PDXs) to assess chemosensitivity to anti-cancer agents in real-time may improve cancer care by enabling individualized clinical decision-making. However, it is unknown whether this new approach will be met with acceptance by patients, family and community. METHODS: We used a cross-sectional structured survey to investigate PDX acceptability with 1550 individuals across Australia and New Zealand (648 survivors of adult and childhood cancer, versus 650 community comparisons; and 48 parents of childhood cancer survivors versus 204 community parents)...

'Wanting' and 'liking' are mediated by distinct brain reward systems but their dissociation in human appetite and overeating remains debated. Further, the influence of socioemotional cues on food reward is little explored. We examined these issues in overweight/obese (OW/OB) and normal-weight (NW) participants who watched food images varying in palatability in the same time as videoclips of avatars looking at the food images while displaying facial expressions (happy, disgust or neutral) with their gaze directed only toward the food or consecutively toward the food and participants...

In virtual reality (VR), avatars are graphical representations of people. Previous research highlights benefits of having a self-avatar when perceiving-acting while embedded in a virtual environment. We studied the effect that an altered avatar had on the perception of one's action capabilities. In Experiment 1, some participants acted with a normal, or faithful, avatar whereas another group of participants used an avatar with an extended arm, all in virtual reality. Experiment 2 utilized the same methodology and procedure as Experiment 1, except that only a calibration phase occurred in VR, whereas other phases were completed in the real world...

When we produce actions we predict their likely consequences. Dominant models of action control suggest that these predictions are used to 'cancel' perceptual processing of expected outcomes. However, normative Bayesian models of sensory cognition developed outside of action propose that rather than being cancelled, expected sensory signals are represented with greater fidelity (sharpened). Here, we distinguished between these models in an fMRI experiment where participants executed hand actions (index vs little finger movement) while observing movements of an avatar hand...

Background: Phantom limb pain (PLP) is commonly seen following upper extremity (UE) amputation. Use of both mirror therapy, which utilizes limb reflection in a mirror, and virtual reality therapy, which utilizes computer limb simulation, has been used to relieve PLP. We explored whether the Virtual Integration Environment (VIE), a virtual reality UE simulator, could be used as a therapy device to effectively treat PLP in individuals with UE amputation. Methods: Participants with UE amputation and PLP were recruited at Walter Reed National Military Medical Center (WRNMMC) and instructed to follow the limb movements of a virtual avatar within the VIE system across a series of study sessions...

Previous social exclusion experiments identified two factors affecting the participants' evaluation of participation in a virtual ball tossing game (cyberball): ball reception probability and vertical position of the participant's avatar on the screen. The P3 component in the event-related brain potentials (ERPs) indicated that both factors moderate subjective expectancies on social participation. The present research builds on an expectancy model explaining these effects and tests whether its predictions - established in a within-participant design - also hold in a between-participant design more common in behavioral cyberball studies...

PURPOSE: With the recent introduction of fully assisting scanner technologies by Siemens Healthineers (Erlangen, Germany), a patient surface model was introduced to the diagnostic imaging device market. Such a patient representation can be used to automate and accelerate the clinical imaging workflow, manage patient dose, and provide navigation assistance for computed tomography diagnostic imaging. In addition to diagnostic imaging, a patient surface model has also tremendous potential to simplify interventional imaging...

BACKGROUND AND AIMS: Effective strategies are needed to address the need for scheduling support in the unique setting of a home rehabilitation service, providing home based therapy, as well as telerehabilitation. One approach is an electronic avatar-directed scheduling and memory aid in the form of an app. The aim of this study is to investigate clinician perspectives on the use of this type of technology. METHODS: In this mixed method study a total of sixteen clinicians from various disciplines based at a metropolitan hospital in Adelaide (SA, Australia) participated in 2 semi-structured focus groups aimed to explore experiences and attitudes towards scheduling support in the form of an avatar-directed app, perceptions on the usefulness of the app, as well as acceptability...

REVIEW
Julia Bachmann, Jörn Munzert, Britta Krüger
Research on the perception of biological human motion shows that people are able to infer emotional states by observing body movements. This article reviews the methodology applied in fMRI research on the neural representation of such emotion perception. Specifically, we ask how different stimulus qualities of bodily expressions, individual emotional valence, and task instructions may affect the neural representation of an emotional scene. The review demonstrates the involvement of a variety of brain areas, thereby indicating how well the human brain is adjusted to navigate in multiple social situations...

BACKGROUND: Impairment of upper extremity function is a common outcome following stroke, to the detriment of lifestyle and employment opportunities. Yet, access to treatment may be limited due to geographical and transportation constraints, especially for those living in rural areas. While stroke rates are higher in these areas, stroke survivors in these regions of the country have substantially less access to clinical therapy. Home therapy could offer an important alternative to clinical treatment, but the inherent isolation and the monotony of self-directed training can greatly reduce compliance...

Logical models are well-suited to capture salient dynamical properties of regulatory networks. For networks controlling cell fate decisions, cell fates are associated with model attractors (stable states or cyclic attractors) whose identification and reachability properties are particularly relevant. While synchronous updates assume unlikely instantaneous or identical rates associated with component changes, the consideration of asynchronous updates is more realistic but, for large models, may hinder the analysis of the resulting non-deterministic concurrent dynamics...
