Anxious People Make Poor Decisions in the Midst of Uncertainty

University of Oxford researchers have found that individuals who are prone to high anxiety have a more difficult time reading the environmental cues that may help them avoid a bad outcome. Participants played a computerized “two-armed bandit-style” game in which they chose between two shapes, one of which, if selected, would deliver a mild to moderate electrical shock. To avoid getting shocked, participants needed to keep track of the shape that most frequently delivered electrical jolts. The researchers noted that highly anxious people had more trouble than their less anxious counterparts adjusting to avoid shocks. Study lead author Dr. Sonia Bishop writes, “Our results show that anxiety may be linked to difficulty in using information about whether the situations we face daily, including relationship dynamics, are stable or not, and deciding how to react.”
