Older adults are disproportionately vulnerable to fraud, and federal agencies have speculated that excessive trust explains their greater vulnerability. Two studies, one behavioral and one using neuroimaging methodology, identified age differences in trust and their neural underpinnings. Older and younger adults rated faces high in trust cues similarly, but older adults perceived faces with cues to untrustworthiness to be significantly more trustworthy and approachable than younger adults. This age-related pattern was mirrored in neural activation to cues of trustworthiness. Whereas younger adults showed greater anterior insula activation to untrustworthy versus trustworthy faces, older adults showed muted activation of the anterior insula to untrustworthy faces. The insula has been shown to support interoceptive awareness that forms the basis of "gut feelings," which represent expected risk and predict risk-avoidant behavior. Thus, a diminished "gut" response to cues of untrustworthiness may partially underlie older adults' vulnerability to fraud. (1) and the Federal Trade Commission (2) have conjectured that older adults' excessive positive responses to other people may underlie their vulnerability. Consistent with this idea, a large body of literature indicates that older adults shape their experiences and social networks in ways that lead to positive socioemotional outcomes (3). As such, older adults' judgments of the trustworthiness of others may also be skewed in a positive direction. Affective judgments of trustworthiness implicate processing in limbic regions, including the amygdala and insula (4, 5). Accordingly, age differences in trust may be reflected in altered patterns of activation in these neural regions.We report the results of two investigations that address how older adults process facial cues indicative of trust differently from younger adults. The first is a behavioral study in which participants rated faces that varied in cues conveying trustworthiness (trustworthy, neutral, untrustworthy) (4). The second study used functional neuroimaging to identify whether facial cues of trustworthiness are processed differently in the brains of older vs. younger adults. We predicted that older adults would perceive people to be more trustworthy and that this pattern would be reflected in lesser insula and/or amygdala responses to the stimuli. Study 1People make many inferences about personal attributes from facial features (6, 7). One fundamental such judgment is whether a person is inherently trustworthy or not (5,8). The present study investigated whether there are reliable age differences in how older and younger adults infer trust from facial cues.Results. Older and younger adults observed faces that had previously been selected to convey cues regarding trustworthiness (trustworthy, neutral, or untrustworthy) (4) and rated them on how trustworthy and approachable the person seemed to be. These ratings were subjected to Age group (younger vs. older) by Face Type (trustworthy, neutral, untrustworthy)...

Much remains unknown regarding the relationship between anxiety, worry, sustained attention, and frontal function. Here, we addressed this using a sustained attention task adapted for functional magnetic resonance imaging. Participants responded to presentation of simple stimuli, withholding responses to an infrequent “No Go” stimulus. Dorsolateral prefrontal cortex (DLPFC) activity to “Go” trials, and dorsal anterior cingulate (dACC) activity to “No Go” trials were associated with faster error-free performance; consistent with DLPFC and dACC facilitating proactive and reactive control, respectively. Trait anxiety was linked to reduced recruitment of these regions, slower error-free performance, and decreased frontal-thalamo-striatal connectivity. This indicates an association between trait anxiety and impoverished frontal control of attention, even when external distractors are absent. In task blocks where commission errors were made, greater DLPFC-precuneus and DLPFC-posterior cingulate connectivity were associated with both trait anxiety and worry, indicative of increased off-task thought. Notably, unlike trait anxiety, worry was not linked to reduced frontal-striatal-thalamo connectivity, impoverished frontal recruitment, or slowed responding during blocks without commission errors, contrary to accounts proposing a direct causal link between worry and impoverished attentional control. This leads us to propose a new model of the relationship between anxiety, worry and frontal engagement in attentional control versus off-task thought.

This study examined neural activation during the experience of compassion, an emotion that orients people toward vulnerable others and prompts caregiving, and pride, a self-focused emotion that signals individual strength and heightened status. Functional magnetic resonance images (fMRI) were acquired as participants viewed 55 s continuous sequences of slides to induce either compassion or pride, presented in alternation with sequences of neutral slides. Emotion self-report data were collected after each slide condition within the fMRI scanner. Compassion induction was associated with activation in the midbrain periaqueductal gray (PAG), a region that is activated during pain and the perception of others' pain, and that has been implicated in parental nurturance behaviors. Pride induction engaged the posterior medial cortex, a region that has been associated with self-referent processing. Self-reports of compassion experience were correlated with increased activation in a region near the PAG, and in the right inferior frontal gyrus (IFG). Self-reports of pride experience, in contrast, were correlated with reduced activation in the IFG and the anterior insula. These results provide preliminary evidence towards understanding the neural correlates of important interpersonal dimensions of compassion and pride. Caring (compassion) and self-focus (pride) may represent core appraisals that differentiate the response profiles of many emotions.
