“…There have been many useful models of body babbling that have been proposed as of late in the robotics literature Lee (2011), making new advances in solving the inverse problems involved in motor planning (Rolf et al, 2010) and representation issues in sensorimotor representations (Law et al, 2013). We view our model as a simplified form of model for body babbling that allows us to ask what kind of impact it has on evolution of animals that engage in it and robots that use genetic algorithms combined with body babbling.…”

“…Also, the MWUA model assumes there are internal reward signals associated with different motor behaviors, and that the ones which are closer to goal-directed are internally rewarded this way. So too does Lee (2011) emphasize the importance of internal rewards and intrinsic motivation as a way to model play, with the latter originally introduced by Furth (1969). …”

As part of the extended evolutionary synthesis, there has recently been a new emphasis on the effects of biological development on genetic inheritance and variation. The exciting new directions taken by those in the community have by a pre-history filled with related ideas that were never given a rigorous foundation or combined coherently. Part of the historical background of the extended synthesis is the work of James Mark Baldwin on his so-called “Baldwin Effect.” Many variant re-interpretations of his work obscure the original meaning of the Baldwin Effect. This paper emphasizes a new approach to the Baldwin Effect, focusing on his work in developmental psychology and how that would impact evolution. We propose a novel population genetics model of the Baldwin Effect. First, the impact of a kind of learning process motivated by motor babbling, in the developmental psychology literature, on evolution; second, that Information-theoretic phenotype reshaping speeds up evolution compared to populations without this kind of learning. The basic idea behind the model is to allow the organism to apply abstraction to his initial phenotype to situate it within one of a few different classes of phenotypes in the local neighborhood of a fitness maximum. The reshaping of the phenotype space thereby allows the organism to reach a nearby fitness maximum. By so doing, valleys in the fitness landscape are leveled out, making a rugged fitness landscape into a set of mesas and plateaus with increasing height. Using this model we can show the first sizeable speed-up for the Baldwin Effect compared to ordinary population genetics. We also introduce an information-theoretic foundation for the Baldwin Effect, which may be of independent interest.

“…Moreover, our work focus on using the “Play” strategy to create the mobile reaching ability for our robot, with the two game modes created. Our system not only involves spontaneous and intrinsically motivated exploration of actions and objects in varying contexts (Lee, 2011 ) but also, contains developmental characteristic by applying the “LCAS” developmental learning algorithm. Without setting specific goals, the robot uses its learning status to develop from the simple game mode to the complex one.…”

Inspired by infant development theories, a robotic developmental model combined with game elements is proposed in this paper. This model does not require the definition of specific developmental goals for the robot, but the developmental goals are implied in the goals of a series of game tasks. The games are characterized into a sequence of game modes based on the complexity of the game tasks from simple to complex, and the task complexity is determined by the applications of developmental constraints. Given a current mode, the robot switches to play in a more complicated game mode when it cannot find any new salient stimuli in the current mode. By doing so, the robot gradually achieves it developmental goals by playing different modes of games. In the experiment, the game was instantiated into a mobile robot with the playing task of picking up toys, and the game is designed with a simple game mode and a complex game mode. A developmental algorithm, “Lift-Constraint, Act and Saturate,” is employed to drive the mobile robot move from the simple mode to the complex one. The experimental results show that the mobile manipulator is able to successfully learn the mobile grasping ability after playing simple and complex games, which is promising in developing robotic abilities to solve complex tasks using games.

“…Rich behaviour can emerge from physical (or virtual) constraints and fundamental low level mechanisms. For example, intrinsic goal free motor activity which underlies babbling may lay an essential foundation for play and cognitive development [Lee 2011]. Intrinsically motivated behaviour has arguably been demonstrated in biologically based models of action discovery [Gurney et al 2013].…”

“…a specialized circuit for vocal babbling has been discovered in the Songbird [Aronov et al 2008]) and it is argued that babbling is a fundamental to cognitive development in autonomous intelligent agents [Lee 2011]. In the model, motor babbling is produced by a specialized recurrent neural network which forms part of the basal ganglia thalamic circuit [Goldberg and Fee 2011].…”

We describe a neurobehavioural modeling and visual computing framework for the integration of realistic interactive computer graphics with neural systems modelling, allowing real-time autonomous facial animation and interactive visualization of the underlying neural network models. The system has been designed to integrate and interconnect a wide range of computational neuroscience models to construct embodied interactive psychobiological models of behaviour. An example application of the framework combines models of the facial motor system, physiologically based emotional systems, and basic neural systems involved in early interactive behaviour and learning and embodies them in a virtual infant rendered with realistic computer graphics. The model reacts in real time to visual and auditory input and its own evolving internal processes as a dynamic system. The live state of the model which generates the resulting facial behaviour can be visualized through graphs and schematics or by exploring the activity mapped to the underlying neuroanatomy. *The development of autonomous interactive virtual agents and social robots is a developing area of research aiming to recreate naturalistic human behaviour in computer graphic or humanoid robotic form. A key idea behind making humanlike digital characters and robots more realistic in appearance and behaviour is that in doing so we open up many more natural channels of communication -we begin to share the same appearance and signaling mechanisms, making for a more fluid interaction between man and machine, whether it is for entertainment or functionality. However creating realistic appearance and behaviour is challenging
