Instead, Brooks and his followers wrote computer programs with simple subprograms that connected sensor inputs to motor outputs, each subprogram encoding a behaviour such as avoiding a sensed obstacle or heading toward a detected goal.
After all, computational models can incorporate sensory inputs and motor outputs.
For innate behaviours - like reproductive behaviour of insects - such neuronal circuits produce observable stereotypic motor outputs.
Facial expressions are communicative motor outputs, whose kinematics likely are due to musculoskeletal anatomy, neuromotor activity and the well-being and internal states of the individual.
Noë (2004) argues that this experiment supports the enactive approach: in order to develop normal visual depth perception it is necessary to learn how motor outputs lead to changes to visual inputs.
Enriched virtual environments might as well increase motor outputs and could be used to better contextualize the observed behaviour.
From a biological perspective, the goal of all nervous systems is to select motor outputs in order to promote the future of an animal's genetic information.
Note that these theories also consider the role of neuromodulators [54] [55] and the nature of motor outputs; i.e. behavioural responses ([22], [56], [57], [58], [59]).
Despite a spontaneous tendency for imitation, most observed actions are not imitated, suggesting that inhibitory mechanisms prevent motor outputs [11], [12].
The current brain activation findings may suggest that neural processes that generate equivalent motor outputs use the same network of brain areas.
Following this notion, the ecologically so advantageous heavy-tailed searching strategy may be brought about by constantly engaging motor outputs and monitoring their effects in a decision-based queuing process.
