We are quite capable of distinguishing those outcomes we cause from those we do not. This ability to sense self-agency is thought to be produced by a comparison between a predictive representation of an outcome and the actual outcome that occurs. It is unclear, though, specifically what types of information can be entered into agency computations. Here, we demonstrate that information from non-target stimuli (stimuli that are not directly acted upon) incidentally present in our surroundings can influence predictions of outcomes, consequently modulating the sense of agency over clearly-defined target outcomes (those that occur to acted-upon stimuli). This provides the first evidence that our sense of agency is contextualized with respect to what is in our immediate visual environment. Furthermore, our data suggest that agency computations, instead of just a single comparison, may involve comparisons performed in stages, with different stages involving different types/classes of information. A model of such multi-stage comparisons is described.

Current lithium batteries experience significant performance degradation under extreme temperature conditions, both high and low. Traditional wide-temperature electrolyte designs typically addressed these challenges by manipulating the solvation sheath and selecting solvents with extreme melting/boiling points. However, these solvent-mediated solutions, while effective at one temperature extreme, invariably fail at the opposite end due to the inherent difficulties in maintaining solvent stability across wide temperatures.

Background: The concept of thriving at work (TAW) has received increased interest within health services research in recent years. TAW embraces employees' experience of being energized and feeling alive when employed in an organization. However, previous research has been limited mainly to the investigation of factors that promote TAW.

Bromopropane was introduced commercially as an alternative to ozone-depleting and global warming solvents. The identification of 1-bromopropane neurotoxicity in animal experiments was followed by reports of human cases of 1-bromopropane toxicity. In humans, the most common clinical features of 1-bromopropane neurotoxicity are decreased sensation, weakness in extremities, and walking difficulties.

A growing body of literature explores the intersection of eating disorders and identity formation-an entanglement that makes eating disorders particularly challenging to treat. Narrative medicine is a discipline of the health humanities that is interested in bearing witness to patients' stories with a closeness and rigor that enhances clinical care. The pedagogy of the field is the narrative medicine workshop, which mobilizes close-reading of works of art and reflective writing to improve our understanding of Self and Other.

Functional Motor Disorders (FMD) consists in symptoms of altered motor function not attributable to typical neurological and medical conditions. This study aimed to explore explicit and perceptual measures of Sense of Ownership, Agency, and Body Schema in FMD patients, and assess whether these alterations are specific to FMD or shared with other functional disturbances. Twelve FMD patients, ten with Irritable Bowel Syndrome (IBS, a functional gastrointestinal disorder) and fifteen healthy controls (HC) underwent: (i) the Mirror Box Illusion (MBI), requiring participants to perform tapping movements with their dominant hand concealed from sight, while visual feedback was provided by an alien hand under visuo-motor congruency or incongruency conditions; (ii) a Forearm Bisection Task before and after exposure to the MBI, and the Embodiment Questionnaire after the MBI, as perceptual and explicit indices of the embodiment illusion, respectively.
