reaction time

Biology

The period of time between the detection of a stimulus at a sensory receptor and the performance of the appropriate response by the effector organ. This delay is caused by the time taken for the impulse to travel across the synapses of adjacent neurons. The reaction time for a reflex response, involving only a single linking synapse, is very short.

Geology and Earth Sciences

1. In geomorphology, the time taken for a system to react to a sustained change in external conditions. Representative reaction times are difficult to define, because of variations both in the resistance of systems to change and in the magnitude of the external change. For example, a sand-bed river channel reacts more readily to change than does a rock-floored channel. See also relaxation time.
2. See corona.

Geography

The time between any kind of change and the response it elicits in a system. In geomorphology it is the interval between a disturbance or change in controls and observable morphological change. In hydrology, the bigger a catchment, the longer its reaction time. Harrison (2003) Am. Geophys. Union C22A-01 extends this term to glaciers, but Oerlemans (2007) J. Glaciol. 53, 182 thinks that reaction time is not a well-defined concept, ‘because the reaction time may depend on the glacier/climate history in a non-transparent way’.
