The initial emphasis of enactivism upon sensorimotor skills has been criticized as "cognitively marginal",[1] but it has been extended to apply to higher level cognitive activities, such as social interactions.[2] "In the enactive view,... knowledge is constructed: it is constructed by an agent through its sensorimotor interactions with its environment, co-constructed between and within living species through their meaningful interaction with each other. In its most abstract form, knowledge is co-constructed between human individuals in socio-linguistic interactions...Science is a particular form of social knowledge construction...[that] allows us to perceive and predict events beyond our immediate cognitive grasp...and also to construct further, even more powerful scientific knowledge."[3]
