The discussion about environmental influence on ontogeny has fueled the question about how much context manipulation can regulate individuals’ characteristics. Today, scientific evidence from different fields (e.g., developmental psychology, neuroscience) describes not only how environment can modulate brain development and function, but also the plastic mechanisms involved. In consequence, different methodological approximations of early stimulation (ES) have arisen, although they are not necessarily based on solid empirical evidence. In this context, a brief approximation to the ES background is provided, as well as a general framework about brain plasticity. In addition, the theoretical and practical perspective of the ES practitioners is also described by detailing the empirical evidence around its most known/used variants in Costa Rica (i.e., Doman-Delacato, Snoezelen®, Point and Bebé políglota). Finally, bringing up the scope and limitations of ES, we conclude that the professional experiences need to be systematized, in order to open an academic debate on the subject.
