Fetal androgen exposure and childhood experiences are believed to contribute to the development and organization of the hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes, which are responsible for the regulation and release of stress and sex hormones, respectively. Evidence suggests the HPA and HPG axes can couple in response to childhood adversity, and that hormonal dysregulation contributes to psychopathological disorders such as anxiety and depression. Recent research also suggests self-compassion interventions could reduce PTSD symptoms, and that the experience of childhood trauma is related to increased empathy. Still, little is known regarding the impact of fetal androgen exposure on PTSD susceptibility and the relationships between self-compassion, compassion for others, and empathy. The current study aims to determine whether fetal androgen exposure mitigates PTSD susceptibility, and to clarify the relationships between empathy, compassion for others, self-compassion, and PTSD symptoms. A sample of 208 adults completed an online survey designed to measure fetal androgen exposure, childhood maltreatment, self-compassion, compassion for others, empathy, and PTSD symptoms. Findings show a significant difference in PTSD symptoms between individuals in high and low fetal androgen exposure groups, and significant correlations were discovered between empathy and compassion for others, empathy and self-compassion, but not compassion for others and self-compassion. Future studies could explore the extent to which fetal androgen exposure influences PTSD symptom susceptibility and the clinical implications therein.
Currently, autonomous vehicles are being evaluated by how well they interact with humans without evaluating how well humans interact with them. Since people are not going to unanimously switch over to using autonomous vehicles, attention must be given to how well these new vehicles signal intent to human drivers from the driver’s point of view. Ineffective communication will lead to unnecessary discomfort among drivers caused by an underlying uncertainty about what an autonomous vehicle is or isn’t about to do. Recent studies suggest that humans tend to fixate on areas of higher uncertainty so scenarios that have a higher number of vehicle fixations can be reasoned to be more uncertain. We provide a framework for measuring human uncertainty and use the framework to measure the effect of empathetic vs non-empathetic agents. We used a simulated driving environment to create recorded scenarios and manipulate the autonomous vehicle to include either an empathetic or non-empathetic agent. The driving interaction is composed of two vehicles approaching an uncontrolled intersection. These scenarios were played to twelve participants while their gaze was recorded to track what the participants were fixating on. The overall intent was to provide an analytical framework as a tool for evaluating autonomous driving features; and in this case, we choose to evaluate how effective it was for vehicles to have empathetic behaviors included in the autonomous vehicle decision making. A t-test analysis of the gaze indicated that empathy did not in fact reduce uncertainty although additional testing of this hypothesis will be needed due to the small sample size.
