Quick Summary

Orthokinesis is a type of unlearned behavioral response to a stimulus, characterized by undirected movement. It involves an organism's rate of locomotion or frequency of turning in response to a stimulus, rather than a directed movement towards or away from it.12

For example, some organisms may increase their movement in response to a stimulus, while others might decrease their activity. This type of response is observed in various organisms, including planarians and cockroaches, and is considered a fundamental aspect of an organism's interaction with its environment.12
