Many animals may have a previously under-appreciated ability to make up for lost time with more effort, according to new research publishing this week in PLOS Computational Biology.
Researchers from Princeton University challenge the conventional view that animals face a simple trade-off between the speed and the accuracy of their decisions. Adrian de Froment, Daniel Rubenstein and Simon Levin instead suggest that this picture of a two-way trade-off is missing a crucial third component: an ability to expend effort at a greater rate to compensate for any limit to the time spent making a decision.
