A unity of the self or a multiplicity of locations? How the graphesthesia task sheds light on the role of spatial perspectives in bodily self-consciousness

Integrating multisensory stimuli from a self-centred perspective is crucial for the unity of the self. On the other hand, understanding external space and communicating spatial knowledge with others necessitate the adoption of decentred perspectives. How do we juggle these two requirements? In this article, we review those studies that have used the graphesthesia task in order to investigate the perspectives that people adopt when interpreting ambiguous tactile symbols (e.g., b, d, p, and q). With such ambiguous symbols, self-centred and decentred perspectives conflict with one another. The results reviewed here reveal that the perspectives adopted vary significantly with spatial, personal, and interpersonal factors. Such findings suggest that the self can adopt a multiplicity of spatial locations. However, the unity of the self can partly be explained by the predominance of a head-centred perspective. On the other hand, perspective-taking abilities contribute to the distinction between self and others, reinforcing self-consciousness.     

Are situation awareness and decision-making in driving totally conscious processes? Results of a hazard prediction task

Detecting danger in the driving environment is an indispensable task to guarantee safety which depends on the driver’s ability to predict upcoming hazards. But does correct prediction lead to an appropriate response? This study advances hazard perception research by investigating the link between successful prediction and response selection. Three groups of drivers (learners, novices and experienced drivers) were recruited, with novice and experienced drivers further split into offender and non-offender groups. Specifically, this works aims to develop an improved Spanish Hazard Prediction Test and to explore the differences in Situation Awareness, (SA: perception, comprehension and prediction) and Decision-Making (DM) among learners, younger inexperienced and experienced drivers and between driving offenders and non-offenders. The contribution of the current work is not only theoretical; the Hazard Prediction Test is also a valid way to test Hazard Perception. The test, as well as being useful as part of the test for a driving license, could also serve a purpose in the renewal of licenses after a ban or as a way of training drivers. A sample of 121 participants watched a series of driving video clips that ended with a sudden occlusion prior to a hazard. They then answered questions to assess their SA (“What is the hazard?” “Where is it located?” “What happens next?”) and DM (“What would you do in this situation?”). This alternative to the Hazard Perception Test demonstrates a satisfactory internal consistency (Alpha = 0.750), with eleven videos achieving discrimination indices above 0.30. Learners performed significantly worse than experienced drivers when required to identify and locate the hazard. Interestingly, drivers were more accurate in answering the DM question than questions regarding SA, suggesting that drivers can choose an appropriate response manoeuvre without a totally conscious knowledge of the exact hazard.     

Facial gender confirmation surgery—review of the literature and recommendations for Version 8 of the WPATH Standards of Care

Facial gender confirmation surgery (FGCS), also popularly known and referred to in the scientific literature as facial feminization surgery (FFS), was previously treated as a collection of aesthetic procedures complementing other aspects of gender-confirming surgery. Recent literature on quality-of-life outcomes following FGCS has supported the substantial impact these procedures have on overall well-being and reduction of psychosocial sequelae in patients. The World Professional Association for Transgender Health Standards of Care, Version 7 (WPATH SOC 7), did not deem FGCS a medical necessity. Based on these new studies, increasing evidence points to the need to include FGCS among medically necessary gender-confirming surgeries, though more-prospective studies are needed. Updates to the WPATH SOC 8 are proposed based on available quality of life studies.     

‘If I only had a little humility,I would be perfect’: Children’s and adults’ perceptions of intellectually arrogant,humble, and diffident people

Abstract

Intellectual humility is usually regarded as a virtue. In this paper, we conceptualized intellectual humility along two dimensions: (1) placing an adequate level of confidence in one’s own beliefs; (2) being willing to consider other people’s beliefs. We tested whether children (ages 4 to 11 years) and adults perceived intellectual humility as positive and how these perceptions changed across development. To do so, we asked participants to evaluate an intellectually humble person as compared to an intellectually arrogant person, who readily dismissed other people’s beliefs, or to an intellectually diffident person, who was unsure of a well-supported belief. Young children did not favor the intellectually humble person over the others, but older children and adults liked this person better and tended to consider her nicer than the arrogant one and smarter than the diffident one. These findings suggest that the virtuousness of intellectual humility in others is recognized from mid-childhood on.
