When unpredictability or uncertainty prods us to consider the prospect of a bleak future, it fuels a state of apprehension that scientists study in the form of anxiety. Anxiety sits along a continuum of defensive behaviors we use when threats are somewhat remote from our current experience. It’s less extreme than the full-on fear elicited by direct, acute situations like an immediate physical attack. Anxiety triggers the release of stress hormones and reorganizes our priorities to prepare for a future threat. Cognitive effects include repetitive worries, hyper-vigilant scanning for signs of trouble in the environment, and attentional and memory biases toward threat-related material. rawstory/rs/2014/11/why-youre-so-stressed-out-your-brain-transforms-remote-threats-into-anxiety/
