Mediating influences of social support on stress at Three Mile Island


Symptom reporting, task performance, and urinary catecholamine excretion were studied in a group of people living near the Three Mile Island nuclear power plant and in control populations. More than a year after the accident, living near the damaged reactor was associated with elevations in all indices of stress compared with control levels. Social support mediated these stress indices such that higher levels were associated with fewer psychological and behavioral symptoms of stress. Biochemical measures showed a different pattern of results.

The need for a new medical model: a challenge for biomedicine


The dominant model of disease today is biomedical, and it leaves no room within tis framework for the social, psychological, and behavioral dimensions of illness.

The role of ventromedial prefrontal cortex in anxiety and emotional resilience

The study of brain correlates of emotion in humans has posed a persistent challenge, in part because:a) it is difficult to manipulate and maintain strong emotional statesb) the analysis of state-effects is complicated by low-frequency drift and difficulties in specifying precisely what cognitive and affective operations may give rise to state-related brain activity.In this study, we induced an emotional state using a silent public speech-preparation task that has been shown to provoke anxiety.
