Adolescence is a developmental period marked by heightened attunement to social evaluation. While adults have been shown to enact self-protective processes to buffer their self-views from evaluative threats like peer rejection, it is unclear whether adolescents avail themselves of the same defenses. The present study examines how social evaluation shapes views of the self and others differently across development. = 107 participants ages 10-23 completed a reciprocal social evaluation task that involved predicting and receiving peer acceptance and rejection feedback, along with assessments of self-views and likability ratings of peers. Here, we show that, despite equivalent experiences of social evaluation, adolescents internalized peer rejection, experiencing a feedback-induced drop in self-views, whereas adults externalized peer rejection, reporting a task-induced boost in self-views and deprecating the peers who rejected them. The results identify codeveloping processes underlying why peer rejection may lead to more dramatic alterations in self-views during adolescence than other phases of the lifespan.
Converging behavioral evidence suggests that people respond to experiences of social exclusion with both defensive and affiliative strategies, allowing them to avoid further distress while also encouraging re-establishment of positive social connections. However, there are unresolved questions regarding the cognitive mechanisms underlying people's responses to social exclusion. Here, we sought to gain insight into these behavioral tendencies by using functional magnetic resonance imaging (fMRI) to examine the impact of social exclusion on neural responses to visual scenes that varied on dimensions of sociality and emotional valence. Compared to socially included participants, socially excluded participants failed to recruit dorsomedial prefrontal cortex (dmPFC), a brain region involved in mentalizing, for negative social scenes. Moreover, following social exclusion, dmPFC demonstrated a linear effect of valence, with greater activity to positive social scenes compared to negative social scenes. These results suggest that, following social exclusion, people display a preference for mentalizing about positive social information and tend to avoid negative aspects of their social world.
Human survival depends on identifying targets potentially capable of engaging in meaningful social connection. Using sets of morphed images created from animate (human) and inanimate (doll) faces, we provide converging evidence from across two studies showing that the motivation to connect with other people systematically alters the interpretation of the physical features that signal that a face is alive. Specifically, in their efforts to find and connect with other social agents, individuals who feel socially disconnected actually lower their thresholds for what it means to be alive, consistently observing animacy when fewer definitively human cues are present. From an evolutionary perspective, overattributing animacy may be an adaptive strategy, allowing people to cast a wide net when identifying possible sources of social connection and maximize their opportunities to renew social relationships.
Falls are common adverse events following hospital discharge. However, prevention programs are not tailored for older patients transitioning home. To inform development of transitional fall prevention programs, nine older adults designated as being at risk of falls during hospitalization who were recently discharged home were asked about their perceptions of fall risk and prevention, as well as their knowledge and opinion of materials from the Centers for Disease Control and Prevention Stopping Elderly Accidents, Deaths & Injuries Initiative. Using the constant comparative method, five themes were identified: Sedentary Behaviors and Limited Functioning ; Prioritization of Social Involvement ; Low Perceived Fall Risk and Attribution of Risk to External Factors ; Avoidance and Caution as Fall Prevention ; and Limited Falls Prevention Information During Transition from Hospital to Home . Limited awareness of and engagement in effective fall prevention may heighten recently discharged older adults' risks for falls. Prevention programs tailored to the post-discharge period may engage patients in fall prevention, promote well-being and independence, and link hospital and community efforts.

Adolescents routinely take risks that impact the well-being of the friends they are with. However, it remains unclear when and how consequences for friends factor into decisions to take risks. Here we used an economic decision-making task to test whether risky choices are guided by the positive and negative consequences they promise for peers. Across a large developmental sample of participants ages 12-25, we show that risky decision computations increasingly assimilate friends' outcomes throughout adolescence into early adulthood in an asymmetric manner that overemphasizes protecting friends from incurring loss. Whereas adults accommodated friend outcomes to a greater degree when the friend was present and witnessing these choices, adolescents did so regardless of whether a friend could witness their decisions, highlighting the fundamentality of adolescent social motivations. By demonstrating that outcomes for another individual can powerfully tune an actor's risk tolerance, these results identify a key factor underlying peer-related motivations for risky behavior, with implications for the law and risk-prevention.

As a social species, humans are acutely aware of cues that signal inclusionary status. The present study characterizes behavioral and neural responses when individuals anticipate social feedback. Across two functional magnetic resonance imaging studies, participants (N = 42) made social judgments about supposed peers and then received feedback from those individuals. Of particular interest was the neural activity occurring when participants were awaiting social feedback. During this anticipatory period, increased neural activity was observed in the ventral striatum (VS), a central component of the brain’s reward circuitry, and dorsomedial prefrontal cortex (dmPFC), a brain region implicated in mentalizing about others. Individuals high in rejection sensitivity exhibited greater responses in both the VS and dmPFC when anticipating positive feedback. These findings provide initial insight into the neural mechanisms involved in anticipating social evaluations, as well as the cognitive processes that underlie rejection sensitivity.
Findings from neuroimaging studies suggest that the medial prefrontal cortex (MPFC) differentiates between self and mother in participants from Western cultures, but not in Chinese participants. However, previous research suggests that self-motivated immigrants possess more independent self-construal styles. Thus, it is possible that their independent self-construals might be reflected at the neural level. In the present study, we examined the contribution of the MPFC to self and close other-referential processing of psychological traits in Chinese participants, newly arrived to the United States, in both their native language and in English. We predicted that, contrary to prior findings, the MPFC would differentially represent psychological traits for self and mother. Moreover, this effect would be greatest when performing judgments in English. During fMRI scanning, participants (N = 18) completed a standard self-referential processing task in which they rated whether a series of psychological trait adjectives applied to themselves or to their mothers. Consistent with our hypothesis, we found that the MPFC strongly differentiated between self and mother judgments in both languages. However, we found no effect of language in this task. Finally, the posterior cingulate cortex was uniquely sensitive to self-referential judgments in Chinese. These findings indicate that the MPFC differentiates between self and mother among self-motivated immigrants.
Adults titrate the degree of physical effort they are willing to expend according to the magnitude of reward they expect to obtain, a process guided by incentive motivation. However, it remains unclear whether adolescents, who are undergoing normative developmental changes in cognitive and reward processing, translate incentive motivation into action in a way that is similarly tuned to reward value and economical in effort utilization. The present study adapted a classic physical effort paradigm to quantify age-related changes in motivation-based and strategic markers of effort exertion for monetary rewards from adolescence to early adulthood. One hundred three participants aged 12-23 years completed a task that involved exerting low or high amounts of physical effort, in the form of a hand grip, to earn low or high amounts of money. Adolescents and young adults exhibited highly similar incentive-modulated effort for reward according to measures of peak grip force and speed, suggesting that motivation for monetary reward is consistent across age. However, young adults expended energy more economically and strategically: Whereas adolescents were prone to exert excess physical effort beyond what was required to earn reward, young adults were more likely to strategically prepare before each grip phase and conserve energy by opting out of low reward trials. This work extends theoretical models of development of incentive-driven behavior by demonstrating that layered on similarity in motivational value for monetary reward, there are important differences in the way behavior is flexibly adjusted in the presence of reward from adolescence to young adulthood.
