Abstract
A self-developing device () capable of open-ended development makes use of a special motivational system for selecting which action should be taken on the environment by an associated sensory-motor apparatus (). For a given candidate action, a motivational module () calculates a reward associated with the corresponding values that would be taken by one or more motivational variables that are independent of the nature of the associated sensory-motor apparatus. Preferred motivational variables are dependent on the developmental history of the device (), and include variables quantifying the predictability, familiarity and stability of sensory-motor variables serving as the inputs to the device (). The sensory-motor variables represent the status of the external environment and/or the internal resources () of the sensory-motor apparatus () whose behavior is controlled by the self-developing device (). Open-ended development is enabled by attributing a reward which is proportional to the rate of change of the history-dependent motivational variables.
