We argue that lateralities are not merely a result of phylogenetic processes but reflect probability functions that are influenced by task characteristics and extended practice. We support our argument by empirical findings on lateral biases in early infancy in general, and footedness in particular, and on hand preferences in nonhuman primates.

No. Animals' primary problem is the shaping of movements, guided by and adapting to sensory signals. This requires a narrower class of biorobotic models than that spanned by Webb's dimensions and examples. We claim that all model variables and mechanisms must have real counterparts, input vectors must model known sensor fields, internal state vectors and transformations must model neurophysiological processes, and output vectors must model coordinated muscle signals.

We show that Stoffregen & Bardy's arguments against the assumption of separately functioning senses have more historical antecedents than they give credit for, and that multimodal functioning – primitive in perceptual and brain development – does not require this assumption. What is needed is evidence that biological organisms are indeed detecting and acting upon information in a multimodal (or global) array.
