Embodied Transgender Interactions: Exploring Dyadic Interpersonal Coordination and Decision Making in Virtual Reality

Social cognition is shaped by cultural and social-psychological contexts. Depending on the social cues displayed, the cognitive processes that emerge during embodied social interactions can vary. This study explored the influence of gender diverse social cues on interpersonal coordination and decision-making during dyadic interaction in virtual reality. Participants embodied either a transgender or cisgender avatar and interacted with a transgender confederate (human-controlled virtual agent). Results suggest that transgender embodied women and men displayed more interpersonal affiliation, via their coordination dynamics with the confederate, after an explicit gender identity disclosure. Additionally, cognitive flexibility for ambiguous decisions was influenced by attributions of responsibility made toward the confederate. However, cisgender embodied men did not substantially change their decision-making behaviours or increase their coordination with the confederate. Viscerally taking on the perspective and appearance of a transgender person, achieved through virtual embodiment and interaction, may support positive interactions between cisgender and transgender communities

B-cell responses to vaccination at the extremes of age

Infants and the elderly share a high vulnerability to infections and therefore have specific immunization requirements. Inducing potent and sustained B-cell responses is as challenging in infants as it is in older subjects. Several mechanisms to explain the decreased B-cell responses at the extremes of age apply to both infants and the elderly. These include intrinsic B-cell limitations as well as numerous microenvironmental factors in lymphoid organs and the bone marrow. This Review describes the mechanisms that shape B-cell responses at the extremes of age and how they could be taken into account to design more effective immunization strategies for these high-risk age groups
