Abstract: | We analyze how data on the mirror system for grasping in macaque and human ground the mirror system hypothesis for the evolution of the language-ready human brain, and then focus on this putative relation between hand movements and speech to contribute to the understanding of how it may be that a schizophrenic patient generates an action (whether manual or verbal) but does not attribute the generation of that action to himself. We make a crucial discussion between self-monitoring and attribution of agency. We suggest that verbal hallucinations occur when an utterance progresses through verbal creation pathways and returns as a vocalization observed, only to be dismissed as external since no record of its being created has been kept. Schizophrenic patients on this theory then confabulate the agent. |
