The rate of sampling is higher in red light than in blue and in loud noise than in quietness. We suggest that monkeys 'tune' their sampling rate to the a priori probability of change in the environment. date: 1978 date_type: published publication: Perception volume: 7 pagerange: 343-348 refereed: TRUE citation: Humphrey, Nicholas K and Keeble, Graham R (1978) Effects of red light and loud noise on the rate at which monkeys sample the sensory environment.
