“THE VOICES IN OUR HEADS”
“Verbal rehearsal of material — the shopping list you recite as you walk the aisles of a supermarket — is part of our working memory system. But for some of us talking to ourselves goes much further: it’s an essential part of the way we think. Others experience auditory hallucinations, verbal promptings from voices that are not theirs but those of loved ones, long-departed mentors, unidentified influencers, their conscience, or even God…
Fernyhough has based his research on the hunch that talking to ourselves and hearing voices — phenomena that he sees as related — are not mere quirks, and that they have a deeper function…
In his work at Durham, Fernyhough participated in an experiment in which he had an inner conversation with an old teacher of his while his brain was imaged by fMRI scanning. Naturally, the scan showed activity in parts of the left hemisphere associated with language. Among the other brain regions that were activated, however, were some associated with our interactions with other people. Fernyhough concludes that “dialogic inner speech must therefore involve some capacity to represent the thoughts, feelings, and attitudes of the people with whom we share our world.” This raises the fascinating possibility that when we talk to ourselves a kind of split takes place, and we become in some sense multiple: it’s not a monologue but a real dialogue…
Romme came to sympathize with her point of view, and decided that it was vital to engage seriously with the actual content of what patients’ voices said. The pair started to publicize the condition, asking other voice-hearers to be in touch. The movement grew from there. It currently has networks in twenty-four countries, with more than a hundred and eighty groups in the United Kingdom alone, and its membership is growing in the United States. It holds meetings and conferences in which voice-hearers discuss their experiences, and it campaigns to increase public awareness of the phenomenon…
Fernyhough and his colleagues have tried to quantify this phenomenon. Ninety-one writers attending the 2014 Edinburgh International Book Festival responded to a questionnaire; seventy per cent said that they heard characters speak. Several writers linked the speech of their characters to inner dialogues even when they are not actively writing. As for plot, some writers asserted that their characters “don’t agree with me, sometimes demand that I change things in the story arc of whatever I’m writing.”
