*4.3.2 Hierarchization*

The representation of hierarchical language schemas (trees, skeletal events, semantic arborescence, featural arborescence, etc.) is a computational model supported by both computation vs algorithm distribution of minimalist syntax theory and many recent theories of language [108]. Motor hierarchy and abstraction hierarchy ground in mirror neurons frame or adopt other neurocognitive approaches. Links have been advocated between Mirror neuron system and the motor theory of speech perception within the consideration that hierarchy in instantiation relates always on the role of abstract higher levels. This model of consciousness and abstraction [109] includes motor control hierarchy and representation (derivation) into one framework. Moreover, a strict distinction is needed between anatomical location and hierarchy principles. Beyond actual dual models of speech (DIVA model [110]). We will thus refer to the hierarchical model of Dana Ballard suggesting a specification of speech sensory-motor brain abstraction.
