Past research suggests that these metaphors have some measure of psychological reality: people are faster to respond to valenced words and faces when they are presented in metaphor-congruent regions of space.

Environmental noise can cause an exponential reduction in the mean time to extinction (MTE) of an isolated population. We study this effect on an example of a stochastic birth-death process with rates modulated by a colored (that is, correlated) Gaussian noise. A path integral formulation yields a transparent way of evaluating the MTE and finding the optimal realization of the environmental noi...
