The Bactra Review An Introduction
to Natural Computation
For a good introductory account of both signal-detection and foraging theory,
along with studies of animal learning, perception, communication, etc., see
Sara J. Shettleworth, Cognition, Evolution and Behavior (Oxford
UP, 1998).
Recent experiments show that decision-theoretic variables are detectably
encoded at the neural level, at least in rhesus monkeys: see Michael L. Platt
and Paul W. Glimcher, ``Neural Correlates of Decision Variables in Parietal
Cortex,'' Nature 400 (1999): 233--238.
