Adolescence is characterized by extensive neural development and sensitivity to social context, both of which contribute to engaging in prosocial behaviors. Although it is established that prosocial behaviors are linked to positive outcomes in adulthood, little is known about the neural correlates of adolescents’ prosociality. Identifying whether the brain is differentially responsive to varying types of social input may be important for fostering prosocial behavior. We report pilot results using new stimuli and an ecologically valid donation paradigm indicating (1) brain regions typically recruited during socioemotional processing evinced differential activation when adolescents evaluated prosocial compared with social or noninteractive scenes (N = 20, ages 13–17 years, MAge = 15.30 years), and (2) individual differences in temporoparietal junction recruitment when viewing others’ prosocial behaviors were related to adolescents’ own charitable giving. These novel findings have significant implications for understanding how the adolescent brain processes prosocial acts and for informing ways to support adolescents to engage in prosocial behaviors in their daily lives.  相似文献

Extending previous research on the characteristics associated with adolescents’ general tendency to be a moral rebel (Sonnentag & Barnett, 2016), the present study examined the roles of moral identity and (general and situation-specific) moral courage characteristics on 3 (i.e., caring, just, and brave) expressions of the tendency to stand up for one’s beliefs and values despite social pressure not to do so. Results revealed that general and situation-specific moral courage characteristics are important motivators of individuals’ caring, just, and brave expressions of the tendency to be a moral rebel, especially when they possess a relatively strong moral identity.  相似文献

In response to the need for a more diverse workforce, our medical school developed new policies and procedures that focus on the recruitment and selection of diverse students with a specific focus on those considered underrepresented in medicine. To understand what these students bring to the practice of medicine, researchers investigated their perception of their cultural assets and how they plan to use these assets as physicians. A cross-section of 23 ethnically, culturally, and geographically diverse medical students were interviewed and data were analyzed through phenomenographical methods. The results indicate that students view themselves as having multiple assets that could be of significant value in their future practice of medicine, including: a) an interest in science and access to family members in medicine, b) personal and familial struggles with health, c) self and family as immigrants, and d) strong family and community orientations. Students perceived these as cultural assets because they could directly identify where these assets could be valuable in medicine but questioned how to maintain them throughout medical school. Now that our institution has identified these assets, next steps include administrators' investigation of ways to leverage them through curricular and educational programs.  相似文献

Patients and health care consumers can obtain access to their “raw,” or uninterpreted, genetic data from direct-to-consumer genetic testing companies, researchers, or providers and pursue self-directed analysis via third-party interpretation tools. Yet relatively little is known about the nature of currently available interpretation tools or the motivations of tool developers. We conducted a structured content analysis of 23 third-party interpretation tool websites and supporting information, tracking features such as types of information returned, modes of generating and presenting that information, and privacy and security measures. We additionally conducted qualitative interviews with a subset of 10 tool developers. A majority of tools (16 of 23, or 70%) offer some type of health or wellness-related information, often extracted from publicly available variant annotation databases. Half of those interviewed characterized their activities as “bridging” users to the scientific literature rather than interpretation, for which they gave a variety of scientific, ethical, and regulatory justifications. The scale, heterogeneity, and complexity of information available from third-party interpretation are unprecedented. While developers aim to enlighten and empower tool users, interpretation-free “bridging” to rapidly evolving databases may instead impose burdens on genetic counselors and other health care providers asked to provide further contextualization and explanation.  相似文献

This paper explores patients’ views and experiences of undergoing treatment-focused BRCA1 and BRCA2 genetic testing (TFGT), either offered following triaging to clinical genetics (breast cancer) or as part of a mainstreamed care pathway in oncology (ovarian cancer). Drawing on 26 in-depth interviews with patients with breast or ovarian cancer who had undergone TFGT, this retrospective study examines patients’ views of genetic testing at this point in their care pathway, focusing on issues, such as initial response to the offer of testing, motivations for undergoing testing, and views on care pathways. Patients were amenable to the incorporation of TFGT at an early stage in their cancer care irrespective of (any) prior anticipation of having a genetic test or family history. While patients were glad to have been offered TFGT as part of their care, some questioned the logic of the test’s timing in relation to their cancer treatment. Crucially, patients appeared unable to disentangle the treatment role of TFGT from its preventative function for self and other family members, suggesting that some may undergo TFGT to obtain information for others rather than for self.  相似文献

Reflective functioning (RF) is a measure of mentalization—the capacity to think about one’s own and others’ thoughts and feelings and to understand the connections between mental states and behaviors. Previous research indicates a decline in marital quality across the transition to parenthood, and some studies have found that parents are less happy than non-parents. Thus, researchers have called for research into possible moderators of these patterns. RF may help couples navigate this transition by more easily taking each other’s (and the infant’s) perspective and understanding each other’s behaviors. Much of the research on RF has focused on mothering behavior; research has not yet examined associations between RF and other family interactions. We examined associations between RF and marital and coparenting quality for both wives and husbands. Reflective functioning was coded from Adult Attachment Interviews conducted during pregnancy. We assessed marital quality at 3.5 months, and coparenting quality at 13 months, after the birth of the target child. Wives’ higher RF was associated with higher levels of positive—and lower levels of negative—marital and coparenting interactions. Wives who were better able to reflect on their early experiences with their parents were involved in marital interactions that were more positive and supportive and less conflicted and undermining. Husbands’ RF did not predict marital or coparenting quality. These findings highlight the importance of reflective functioning in understanding family functioning.  相似文献

Many researchers have reported elevated rates of emotional, behavioral, and social competence problems (EBSP) in children with epilepsy. Although executive function has been found to be associated with EBSP in children with typical development, almost no research has looked at the individual components of executive function as potential predictors of EBSP in children with epilepsy. This is surprising given the deficits in executive function in children with epilepsy. We investigated EBSP and executive function in 42 children with epilepsy, aged 6.0 to 18.1 years and found, as expected, that EBSP were associated with executive function in these children even after epilepsy-related variables, such as seizure type, were accounted for. However, different components of executive function were related to different emotional, behavioral, and social competence problems in these children. Shifting of mental sets was a significant predictor of emotional, behavioral, and social competence problems whereas inhibition was a significant predictor of behavioral problems. This suggests that different executive function profiles in children with epilepsy may place them at-risk for developing different types of emotional, behavioral, and social competence problems. These results may help researchers and clinicians develop new techniques to identify and treat emotional, behavioral, and social competence problems in children with epilepsy.  相似文献

Adolescents experiencing social anxiety often experience co-occurring attention-deficit/hyperactivity disorder (ADHD) symptoms. Yet, assessing for social anxiety poses challenges given the already time-consuming task of distinguishing social anxiety from other commonly co-occurring internalizing conditions (e.g., generalized anxiety, major depression). Assessors need short screening devices to identify socially anxious adolescents in need of intensive ADHD assessments. A six-item version of the ADHD Self-Report Scale (ASRS-6) was originally developed to identify adults who likely meet diagnostic criteria for ADHD, but its psychometric properties have yet to be examined among adolescents. We tested the psychometric properties of the ASRS-6 when administered in clinical assessments for adolescent social anxiety. Eighty-nine 14–15 year old adolescents and their parents (67.4% female; 62.1% African American; 30 Clinic-Referred; 59 Community Control) completed the ASRS-6, measures of adolescent social anxiety and depressive symptoms, and parent-adolescent conflict. Adolescent self-reported and parent-reported ASRS-6 positively related with scores from established measures of social anxiety, depressive symptoms, and parent-adolescent conflict. Further, adolescent self-reported (but not parent-reported) ASRS-6 scores significantly discriminated adolescents on referral status. Adolescent self-reported (but not parent-reported) ASRS-6 scores incrementally predicted social anxiety over-and-above depressive symptoms, which commonly co-occur with social anxiety. Conversely, parent-reported (but not adolescent self-reported) ASRS-6 scores incrementally predicted parent-adolescent conflict over-and-above depressive symptoms, which commonly co-occur with conflict. When assessing adolescent ADHD symptoms, adolescents’ and parents’ reports meaningfully vary in their links to validity indicators. As such, among adolescents assessed for social anxiety, clinical assessments of adolescent ADHD symptoms should include both parent reports and adolescent self-reports.  相似文献
