Economic Insecurity Increases Physical Pain

The past decade has seen a rise in both economic insecurity and frequency of physical pain. The current research reveals a causal connection between these two growing and consequential social trends. In five studies, we found that economic insecurity produced physical pain and reduced pain tolerance. In a sixth study, with data from 33,720 geographically diverse households across the United States, economic insecurity predicted consumption of over-the-counter painkillers. The link between economic insecurity and physical pain emerged when people experienced the insecurity personally (unemployment), when they were in an insecure context (they were informed that their state had a relatively high level of unemployment), and when they contemplated past and future economic insecurity. Using both experimental-causal-chain and measurement-of-mediation approaches, we also established that the psychological experience of lacking control helped generate the causal link from economic insecurity to physical pain. Meta-analyses including all of our studies testing the link from economic insecurity to physical pain revealed that this link is reliable. Overall, the findings show that it physically hurts to be economically insecure.

Pleasure Now, Pain Later: Positive Fantasies About the Future Predict Symptoms of Depression

Though common sense suggests that positive thinking shelters people from depression, the four studies reported here showed that this intuition needs to be qualified: Positive thinking in the form of fantasies about the future did indeed relate to decreased symptoms of depression when measured concurrently; however, positive fantasies predicted more depressive symptoms when measured longitudinally. The pattern of results was observed for different indicators of fantasies and depression, in adults and in schoolchildren, and for periods of up to 7 months (Studies 1–4). In college students, low academic success partially mediated the predictive relation between positive fantasies and symptoms of depression (Study 4). Results add to existing research on the problematic effects of positive fantasies on performance by suggesting that indulging in positive fantasies predicts problems in mental health.

Conceptual Conditioning: Mechanisms Mediating Conditioning Effects on Pain

Classical conditioning can profoundly modify subsequent pain responses, but the mechanisms that drive this effect are unresolved. In pain-conditioning studies, cues are typically conditioned to primary aversive reinforcers; hence, subsequent pain modulation could reflect learned precognitive associations (i.e., those involving neural plasticity independent of expectations and other forms of conceptual thought) or conceptual expectancies. We isolated conceptual contributions using a thermal pain-conditioning procedure in which different conditioned stimulus (CS) cues were repeatedly paired with symbolic representations of high and low noxious heat. In a subsequent test phase, identical noxious stimuli evoked larger skin conductance responses (SCRs) and pain ratings when preceded by CS cues associated with high temperature than by those associated with low temperature. These effects were mediated by participants’ self-reported expectancies. CS cues associated with high temperature also evoked larger anticipatory SCRs than did CS cues associated with low temperature, but larger anticipatory SCRs predicted smaller subsequent heat-evoked SCRs. These results provide novel evidence that conditioned modulation of pain physiology can be acquired through purely conceptual processes, and that self-reported expectancies and physiological threat responses have opposing effects on pain.
