“…A rich body of literature has demonstrated evidence of corticostriatal response during reward-related tasks (J. P. Bhanji & Delgado, 2014; Dobryakova & Smith, 2022; Knutson et al, 2000; O’Doherty et al, 2017; Sazhin et al, 2020), noting links between the areas described as the “social brain” and the striatum when introducing social context (Fareri et al, 2022; Fareri & Delgado, 2014; Kwon et al, 2022; Lockwood et al, 2020). Likewise, trait reward sensitivity has been noted as a significant factor in neural reward response (Chat et al, 2022).…”

“…We also found that sharing rewards with close friends enhances connectivity between the VS and the posterior temporoparietal junction (pTPJ). These two regions have previously been individually implicated in the enhancing effects of social context and close social relations (Fareri et al, 2022; Park et al, 2017). However, this result is the first to directly link connectivity between the VS and pTPJ with increased response to close friends relative to strangers, expanding upon evidence linking connectivity between the regions with pro-social sharing of monetary funds (Park et al, 2017).…”

“…Additionally, our study had limited variability in participant age, focusing on young adults between the ages of 19-25. Given that adolescents and older adults show differential VS responses in social contexts (Fareri et al, 2022; Gadassi Polack et al, 2023; O’Brien et al, 2011; A. R. Smith et al, 2015; Telzer et al, 2013), the effects of reward sensitivity on monetary reward response in social contexts require further research across the human lifespan.…”

Although prior research has demonstrated enhanced striatal response when sharing rewards with close social connections, less is known about how individual differences affect ventral striatal (VS) activation and connectivity when experiencing rewards within social contexts. Given that self-reported reward sensitivity and level of substance use have been associated with differences in VS activation, we set out to investigate whether these factors would be independently associated with enhancements to neural reward responses within social contexts. In this pre-registered study, participants (N=45) underwent fMRI while playing a card guessing game in which correct or incorrect guesses resulted in monetary gains and losses that were shared evenly with either a close friend, stranger (confederate), or non-human partner. Consistent with our prior work, we found increased VS activation when sharing rewards with a socially close peer as opposed to an out-of-network stranger. As self-reported reward sensitivity increased, the difference in VS response to rewards shared with friends and strangers decreased. We also found enhanced connectivity between the VS and temporoparietal junction when sharing rewards with close friends as opposed to strangers. Finally, exploratory analyses revealed that as reward sensitivity and sub-clinical substance use increase, the difference in VS connectivity with the right fusiform face area increases as a function of social context. These findings demonstrate that responsivity to the context of close friends may be tied to individual reward sensitivity or sub-clinical substance use habits; together these factors may inform predictions of risk for future mental health disorders.

“…Each item asks how much money a participant would invest for a prospective higher return with a person who could choose to either split the multiplied amount evenly (reciprocate) or retain it for themselves (defect). The person was either a hypothetical friend in two of the items or a hypothetical stranger in the other two items (adopted from Fareri et al, 2022 ). Participants were asked to indicate how much in dollars they would share with the other person (e.g., how much out of $28.…”

People lose tens of billions of dollars a year to financial exploitation in the United States alone. Few studies have examined how preferences for trust and fairness in economic activities may contribute to risk for financial exploitation. Furthermore, few studies have examined the interaction between risk factors. In three studies, we attempt to address these gaps by surveying 1918 demographically and socioeconomically diverse participants to examine putative risk factors for self-reported financial exploitation. We focused on: 1) how trust in others and fairness preferences during economic games are associated with self-reported financial exploitation; and 2) how sociodemographic and health-related factors interact with psychosocial factors to confer risk for financial exploitation. We found participants with lower socioeconomic status and poor emotion regulation skills were at the greatest risk for financial exploitation. We also found associations between greater risk for financial exploitation and poorer physical health, more severe cognitive decline, increased persuadability, and increased insensitivity to trustworthiness cues. Our findings suggest that risk for financial exploitation is dependent upon a combination of psychosocial, sociodemographic and health factors, which may lead to interventions that protect vulnerable individuals.

“…Cassidy et al (2021), for example, found a stronger positive relationship between caudate activity and trustworthiness ratings among older than young adults for in-group (i.e., same-race) faces. Similarly,Fareri et al (2022) found greater striatal activity in response to receiving investment from friends compared to strangers among young adults, with this pattern reversed in older adults. Following up on the current findings, future studies could probe differential involvement of the reward network in facial trustworthiness perception for negative compared to positive emotions for own-age vs. other-age faces across adulthood.…”

Objectives Trust is crucial for successful social interaction across the lifespan. Perceiver age, facial age and facial emotion have been shown to influence trustworthiness perception, but the complex interplay between these perceiver and facial characteristics has not been examined. Method Adopting an adult lifespan developmental approach, 199 adults (aged 22-78 years) rated the trustworthiness of faces that systematically varied in age (young, middle-aged, older) and emotion (neutral, happy, sad, fearful, angry, disgusted) from the FACES Lifespan Database. Results The study yielded three key results. First, on an aggregated level, facial trustworthiness perception did not differ by perceiver age. Second, all perceivers rated young faces as most trustworthy; and middle-aged and older (but not young) perceivers rated older faces as least trustworthy. Third, facial emotions signaling threat (fear, anger, disgust) relative to neutral, happy, and sad expressions, moderated age effects on facial trustworthiness perception. Discussion Findings from this study highlight the impact of perceiver and facial characteristics on facial trustworthiness perception in adulthood and aging and have potential to inform first impression formation, with effects on trait attributions and behavior. This publication also provides normative data on perceived facial trustworthiness for the FACES Lifespan Database.
