Embodiment enables non-predictive ways of coping with self-caused sensory stimuli

Living systems process sensory data to facilitate adaptive behavior. A given sensor can be stimulated as the result of internally driven activity, or by purely external (environmental) sources. It is clear that these inputs are processed differently—have you ever tried tickling yourself? Self-caused stimuli have been shown attenuated compared externally caused stimuli. classical explanation this effect when brain sends a signal would in motor it uses copy predict consequences resulting activity. The predicted input then subtracted from actual input, attenuation To critically evaluate utility predictive approach for coping with self-caused stimuli, and investigate non-predictive solutions may viable, we implement computational model simple embodied system sensorimotor dynamics, use genetic algorithm explore possible model. We find emerge modify their behavior shape avoid inputs, rather than predicting filtering them out. In some cases, take advantage presence inputs. existence demonstrates embodiment provides possibilities interference without need an internal,
