Margit Säde speaks at The Hearing Voices Café about her exhibition “source amnesia” – on text produced in unconventional ways, sometimes as the result of extreme and hallucinatory perception.
Source amnesia is the inability to remember where, when or how previously learned information has been acquired, while retaining the factual knowledge. This branch of amnesia is associated with the malfunctioning of one’s explicit memory. It is likely that the disconnect between having the knowledge and remembering the context in which the knowledge was acquired is due to a dissociation between semantic and episodic memory – an individual retains the semantic knowledge (the fact), but lacks the episodic knowledge to indicate the context in which the knowledge was gained.

What is most problematic for the development of any inner speech account of auditory hallucinations is that we still know next to nothing about thought itself. Until we have some idea of the nature of thought and how the brain produces it, it remains very hard to assess how unusual manifestations of it result in auditory hallucinations. How can we know how thoughts relate to voices until we know what thinking itself is like? We have already seen how a traditional corollary discharge account views auditory hallucinations as resulting from efference copy signals from inner speech productions in left Broca’s area not being communicated correctly to the left speech perception regions of the brain, but what other accounts may we consider?
