Movement abnormalities are prevalent across all stages of schizophrenia contributing to poor social functioning and reduced quality of life. To date, treatments are scarce, often involving pharmacological agents, but none have been shown to improve movement abnormalities effectively. Virtual reality (VR) is a tool used to simulate virtual environments where behavioral performance can be quantified safely across different tasks while exerting control over stimulus delivery, feedback and measurement in real time. Sensory information is transmittedviaa head mounted display allowing users to (...) directly interact with virtual objects and bodies using gestures and body movements in the real world to perform different actions, permitting a sense of immersion in the simulated virtual environment. Although, VR has been widely used for successful motor rehabilitation in a variety of different neurological domains, none have been exploited for motor rehabilitation in schizophrenia. The objectives of this article are to review movement abnormalities specific to schizophrenia, and how VR can be utilized to restore and improve motor functioning in patients with schizophrenia. Constructing VR-mediated motor-cognitive interventions that can help in retaining and transferring the learned outcomes to real life are also discussed. (shrink)

We develop a mathematical formalism that allows to study decoherence with a great level generality, so as to make it appear as a geometrical phenomenon between reservoirs of dimensions. It enables us to give quantitative estimates of the level of decoherence induced by a purely random environment on a system according to their respectives sizes, and to exhibit some links with entanglement entropy.

Plato put housing second only to a secure food supply in the order of business of an emerging polis [Republic 2.369d); we argue, without quibbling over rank, that adequate housing ought to have fundamental priority, with health and education, in civil societies' planning, budgets, and legislative agendas. Something made explicit in the Platonic Laws, and often reiterated by today's poor — but as often forgotten by bureaucrats— is that human wellbeing, eudaimonia, is impossible for the homeless. That is, adequate housing (...) is valuable to human societies independently of its instrumental role in supporting the safety, health, and education of the populace. Currently, governments all too frequently end up undermining their own health and education programs as a direct result of neglecting the housing needs of the poor. Finally, we argue that governments ought now to be using the low-cost ways that already exist to provide, or to promote the provision of, better housing for their increasingly urbanized populations; further, even in those circumstances where it is necessary to subsidize housing, governments' most important role is to develop just regulatory and enforcement systems within which public- and private-sector investment can operate.

BackgroundNonverbal social perception is the ability to interpret the intentions and dispositions of others by evaluating cues such as facial expressions, body movements, and emotional prosody. Nonverbal social perception plays a key role in social cognition and is fundamental for successful social interactions. Patients with schizophrenia have severe impairments in nonverbal social perception leading to social isolation and withdrawal. Collectively, these aforementioned deficits affect patients’ quality of life. Here, we compare nonverbal social perception in patients with schizophrenia and controls and (...) examine how nonverbal social perception relates to daily functioning.MethodsWe compared nonverbal social perception in 41 stable outpatients with schizophrenia and 30 healthy controls using the Mini Profile of Nonverbal Sensitivity. The participants evaluated 64 video clips showing a female actor demonstrating various nonverbal social cues. Participants were asked to choose one of two options that best described the observed scenario. We correlated clinical ratings, Self-report of Negative Symptoms, and functional assessments with Mini-PONS scores.ResultsPatients performed significantly poorer in the Mini-PONS compared to controls, suggesting deficits in nonverbal social perception. These deficits were not associated with either positive symptoms or negative symptoms. However, impaired nonverbal social perception correlated with distinctive domains of BNSS, as well as functional capacity and functional outcome in patients.ConclusionWe demonstrate that nonverbal social perception is impaired in stable outpatients with schizophrenia. Nonverbal social perception is directly related to specific negative symptom domains, functional capacity and functional outcome. These findings underline the importance of nonverbal social perception for patients’ everyday life and call for novel therapeutic approaches to alleviate nonverbal social perception deficits.

The supervisor of the activities of a system user should benefit from the knowledge contained in the event logs of the user. They allow the monitoring of the sequential and parallel user activities. To make event logs more accessible to the supervisor, we suggest a process mining approach, including first the design of an understanding model of the activities of a system user. The model design is based on the relationships between the event logs and the activities of a system (...) user. An intervention model completes the understanding model to assist the supervisor. The intervention model enables an action of the supervisor on the critical activities, and the detection of anomalies. The models are automatically designed with a model-driven engineering approach. An experiment on a smart home system illustrates this tooled design, where the supervisor is a medical or paramedical staff member. (shrink)

J.S. Mill has formulated a classical statement of the "argument from analogy� concerning knowledge of other minds: "I must either believe them [other human beings] to be alive, or to be automatons� (Mill 1872, 244). It is possible that Wittgenstein had this in mind when writing the following: "I believe he is suffering.�—Do I also believe that he isn"t an automaton? It would go against the grain to use the word in both connexions. (Or is it like this: I believe (...) he is suffering, but am certain the he is not an automaton? Nonsense!) Suppose I say of a friend: "He isn"t an automaton�.—What information is conveyed by this, and to whom would it be information? To a human being who meets him in ordinary circumstances? What information could it give him? (At the very most that this man always behaves like a human being, and not occasionally like a machine.) "I believe he is not an automaton�, just like that, so far makes no sense. My attitude towards him is an attitude towards a soul [eine Einstellung zur Seele]. I am not of the opinion that he has a soul. (PI p. 178) Here Wittgenstein contrasts opinion (Meinung) and attitude (Einstellung). How should this contrast be understood? On a view such as Mill"s, to regard someone as a conscious being is to hold certain beliefs about him, beliefs that can perhaps ultimately be grounded in a theory of some sort. To have an "attitude towards a soul� is, on the contrary, to see a person"s gestures and facial expressions as "filled with meaning�. We have an attitude towards a soul when confronted with a person, which means that we react to his presence and behaviour in a certain way. (shrink)
