Definitions for kinesiskɪˈni sɪs, kaɪ-
This page provides all possible meanings and translations of the word kinesis
a movement that is a response to a stimulus but is not oriented with respect to the source of stimulation
the movement of an organism in response to an external stimulus
Origin: From κίνησις.
Kinesis, like a taxis, is a movement or activity of a cell or an organism in response to a stimulus. However, unlike taxis, the response to the stimulus provided is non-directional. The two main types of kineses include: Orthokinesis: in which the speed of movement of the individual is dependent upon the intensity of the stimulus. Take, for example, the locomotion of a woodlice in relation to temperature. With increased humidity there is an increase in the percentage time that the woodlice will remain stationary. Klinokinesis: in which the frequency or rate of turning is proportional to stimulus intensity. Both orthokinesis and klinokineses result in aggregations. However, the stimulus does not act to attract or repel individuals. The same prefixes used with "taxis" can be applied to kineses; see also -kinesis. Kinesis is an animal's non-directional response to a stimulus, for example humidity. The animal does not move toward or away from the stimulus but moves at either a slow or fast rate depending on its "comfort zone." In this case a fast movement means that the animal is searching for its comfort zone but a slow movement indicates that it has found it.

Locomotor behavior not involving a steering reaction, but in which there may be a turning random in direction. It includes orthokinesis, the rate of movement and klinokinesis, the amount of turning, which are related to the intensity of stimulation.
