Description: Figure 3: Age-related Differences in Neural Responses to Social Outcomes (A) We found that the anterior insula exhibited a larger response to defect outcomes relative to reciprocate outcomes in younger adults (defect > reciprocate), consistent with the idea that older adults are less sensitive to outcomes associated with losses. (B) For descriptive purposes, we extracted beta values within this anterior insula region and confirmed that older adults showed a blunted response to defect outcomes. (C) In the opposite contrast (reciprocate > defect), we found several regions whose outcome-related activation was enhanced in younger adults. (D) For descriptive purposes, we extracted the response within the posterior cingulate cortex (PCC) and confirmed that the response to reciprocation in this region was enhanced in younger adults. We note that Z statistic images were thresholded parametrically (Gaussian Random Field Theory) using clusters determined by Z>3.1 and a (corrected) cluster significance threshold of P=0.05.
