The developmental trajectory from amodal perception to empathy and communication: The role of mirror neurons in this process

In a recent paper entitled "Mirror Neurons, Procedural Learning and the Pos itive New Experience" (Wolf et al., 2000), data were presented about a spec ial type of neuron, the mirror neuron, originally located by Rizzolatti and his colleagues(1995). These neurons were discussed as they related to a pa rticular developmental view of psychoanalysis, developmental systems self p sychology (Shane, Shane, and Gales, 1997). In this paper, we focus on how this mirror neuron system might contribute t o the development of communicative abilities in humans. First we summarize the research findings about mirror neurons and how they apply to humans. We then attempt to demonstrate how the mirror neuron system might be involved in a developmental sequence hypothesized by Kohut (1984), Stern (1985), an d others to begin in infancy. We postulate that this trajectory starts with the onset of "amodal perception" (Stern, 1985) and then proceeds to affect resonance, joint attention, and ultimately to symbolization of language. I n this paper, we attempt to integrate these concepts with a formulation of empathy and demonstrate what might go awry in developmental disorders when the normative sequence of development described above does not take place.
