Summary: The impact of altered gravitational conditions on the sense of body ownership is a significant area of research. Through the study of unconventional gravity conditions, it has been found that the relative weights of visual, proprioceptive, and vestibular inputs change, favoring vision and increasing susceptibility to the rubber hand illusion.

Summary: It is important to understand how the body representation can be modified, and this study used the Rubber Hand Illusion (RHI) to investigate its temporal dynamics. The feeling of Ownership is established within the first 19 seconds of stimulation and continues to grow, but at a slower pace. The feeling of Ownership disappears within 66 seconds after the stimulation ends, highlighting the malleability of body self-consciousness.

Summary: The study found that in the rubber hand illusion, participants who reported feeling ownership also tended to report touch referral, showing a moderately strong positive relationship between the two. Touch referral was often reported more strongly and frequently than ownership, indicating implications for the experimental paradigm.

Summary: Although the observed proprioceptive drift and subjective reports confirmed the efficacy of inducing illusory hand ownership in the synchronous (vs asynchronous) condition, measures such as heart rate, heart rate variability, electrodermal activity, and SKNA revealed no significant differences in autonomic activity between conditions or between individuals who did or did not experience the rubber hand illusion. Bayes factors indicated substantial evidence for no physiological differences.

Summary: The neurophysiological processes reflecting body illusions such as the rubber hand remain debated. This study recorded EEG responses in human participants and used multivariate classification to identify temporal markers that reliably differentiate the illusory state from non-illusion epochs after approximately 125 and 275 ms following stimulus onset.

Summary: The rubber hand illusion is a widely studied bodily illusion that has been used to investigate the plasticity of body representations in the brain. Recently, there has been an expansion in applying this illusion to children populations to better understand body representation development. To prevent unintended methodological variability from hindering consistency in pediatric literature, it is important to review and summarize available pediatric RHI studies.

Summary: This study investigates the modulation of peripersonal space (PPS) by changes in perceived body ownership. The results show that after induction of a left hand rubber hand illusion, the space around the body shifts to the right for the "synchronous stroking" group. This suggests that the shift in space is mainly driven by multisensory integration of bodily information, rather than feelings of ownership.

Summary: This study analyzes a research on the rubber hand illusion, suggesting that hypnotic suggestibility and expectations have some influence on the illusion, but the main factor is multisensory stimulation. Synchronous stimulation results in a stronger illusion and greater proprioceptive drift compared to asynchronous stimulation. Expectations have a very small effect on the illusion ratings.

Summary: This article investigates the multisensory perception of body ownership and explores the mechanisms underlying the emergence of body ownership illusions such as the visuotactile rubber hand illusion using Bayesian causal inference models. The study finds that proprioception and its relative reliability influence this inferential process and verifies this hypothesis through a rubber hand illusion experiment. The results demonstrate that proprioceptive uncertainty shapes multisensory perception. These findings offer important insights into our understanding of the formation of body ownership.

Summary: In this study, the researchers attempted to replicate the reduction in MEP amplitude associated with the rubber hand illusion (RHI) and identify the components of the illusion that might explain these changes. Despite participants reporting the presence of the illusion and shifts in perceived real hand position towards the fake limb, no reduction in MEP amplitude was observed.

Summary: Enabling sensory feedback in limb prostheses may not be effective for all amputees, as evidenced by the failure to induce the rubber hand illusion in participants with transhumeral amputation; in a study with 30 able-bodied subjects, tapping and stroking were found to equally induce ownership sensations in two-thirds of the participants; participants immune to the rubber hand illusion were still able to experience ownership over prosthetic limbs in daily life, highlighting a significant limitation of the RHI paradigm.

Summary: This study used network analysis to examine the relationship between eating disorder-related psychopathology and carers' responses to anorexia nervosa symptoms in adolescents. Results showed that depression in both carers and patients played a significant role in the maintenance of psychopathology. The findings suggest that depression could be a potential treatment target in family interventions.

Summary: The aim of this study was to examine the processes involved in a guided self-help pre-treatment intervention for patients with anorexia nervosa by measuring the levels of patient/mentor Language Style Matching. The study found that early and late Language Style Matching predicted higher working alliance with the clinic therapist, and late Language Style Matching predicted lower eating disorder symptoms at the end of the intervention. Patient/peer mentor dyads showed higher verbal attunement than patient/student mentor dyads.

Summary: This study examined the effects of attention bias modification treatment (ABMT) on anxiety and attention biases in patients with anorexia nervosa (AN). The results showed that ABMT did not have a significant impact on attention biases, but both ABMT and control conditions were effective in reducing eating disorder symptoms, depression, anxiety, and stress, with no between-group differences in these changes.

Summary: In cases of rape and sexual assault, victims often experience a state of immobility referred to as 'freezing'. Neuroscientific research suggests that this freeze response is a result of fear and threat, which can inhibit the brain circuits responsible for voluntary movement. Thus, defense arguments that blame victims for freezing are inappropriate and unfair.

Summary: The perceived distance between touches can be modulated by certain features of tactile stimuli, such as the time interval between them. This study investigated whether a similar effect exists for stimulus intensity. Results showed that the perceived tactile distance did not change when stimuli intensity differed, but the average stimulus intensity did have a clear impact on perceived distance. These findings support theories of general magnitude representation.

Summary: When reproducing the remembered location of dots within a circle, judgments are biased towards the imaginary center of quadrants formed by imaginary vertical and horizontal axes. This bias can be attributed to the heightened precision in the visual system for these orientations in a retinotopic reference frame, or to the internal representation of gravity. By dissociating reference frames defined by the retina and by gravity, the study found that spatial categories are determined by a combination of both gravitational and retinal factors.

Summary: The aim of this study was to test the usefulness of an add-on serious video game approach (Playmancer) to treatment as usual in reducing impulsive behaviors and psychopathology in individuals diagnosed with an eating disorder. The results showed that the additional treatment with Playmancer improved impulsive behaviors and some facets of trait impulsivity, but there were no significant differences in treatment outcomes between the two groups.

Summary: Treatment for anorexia nervosa remains challenging, with no approved psychopharmacological interventions and variable efficacy of psychotherapeutic strategies. Current evidence suggests deficiencies in neuroplasticity in anorexia nervosa, and this paper provides an overview of neuroimaging, neuropsychological, molecular, and qualitative findings in this area. The findings can be translated into the identification of novel biological and psychotherapeutic strategies to improve the treatment outcomes.
