Fig. 3.

Sagittal slice (X = 56) depicting a probability map in the inferior frontal gyrus (IFG), where the percent signal change in the threat minus safe contrast is greater during stranger handholding than partner handholding as a function of perceived social support (MSPSS, centered on the mean). Scatterplots show the association between percent signal change in the threat-safe contrast and MSPSS for each handholding condition. As perceived social support increases, threat minus related activation in IFG increases during the stranger handholding (r = .19, P = .05), but decreases during partner handholding (r = -.33, P < .001). Notably one participant was an outlier on MSPSS, but results did not change when this participant removed.
