Multiple hypotheses have been offered to explain the impaired face-processing behavior and the accompanying underlying disruptions in neural circuitry among individuals with autism. We explored the specificity of atypical face-processing activation and potential alterations to fusiform gyrus (FG) morphology as potential underlying mechanisms. Adolescents with high functioning autism (HFA) and age-matched typically developing (TD) adolescents were scanned with sMRI and fMRI as they observed human and animal faces. In spite of exhibiting comparable face recognition behavior, the HFA adolescents evinced hypo-activation throughout the face-processing system in response to unfamiliar human, but not animal, faces. They also exhibited greater activation in affective regions of the face-processing network in response to animal, but not human, faces. Importantly, this atypical pattern of activation in response to human faces was not related to atypical structural properties of the FG. This atypical neural response to human faces in autism may stem from abnormalities in the ability to represent the reward value of social (i.e. conspecific) stimuli.
Complex facial expressions provide signals about emotions that are related to nuanced social behavior (e.g., shame, desire) and inner thoughts (e.g., pensive). In this article, we review the empirical evidence evaluating whether the ability to recognize these complex expressions changes during adolescence, given the increasing evidence of heightened sensitivity to social signals during this time. We propose considerations for interpreting findings from this work and shaping research. Finally, we offer a new hypothesis about the influences of age and pubertal maturation on the development of processing complex facial expressions during adolescence, and propose that puberty influences the emergence of sensitivity to particular kinds of complex expressions, namely social sexual expressions. This hypothesis is embedded in a broader theory about how age‐appropriate social developmental tasks, like forming loyal peer friendships and exploring romantic and sexual relationships in adolescence, influence face‐processing behavior.
It is well known that concerns about sexual risk tend to decline among people in intimate relationships where there is established commitment and trust. In the context of relationships at increased risk for HIV transmission, interactions involving disclosure and partner responsiveness are key to maintaining intimacy and physical safety. This paper explores concepts of risk and sexual intimacy articulated by a community sample of 30 people living with HIV and their intimate relationship partners. Data revealed the shifts in intimate relationship dynamics upon the disclosure of an HIV diagnosis, the importance of intimacy in the context of managing one or both partners' HIV care and responses to new advances in HIV prophylaxis. Findings suggest that participants' experiences of self-disclosure and partner responsiveness most often resulted in an increased sense of protectiveness from and for partners. This suggests that health-promoting messaging should be adapted to be more relevant to intimate couple communication and mutual support.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
