 The Imagery Debate is historically significant for yet another reason: it helped us to appreciate how interpersonal variations in mental imagery can have a major impact on one’s philosophical/theoretical positions. An important and fairly large study conducted at a time when the Imagery Debate was on its way out shows this very clearly. It mapped how philosophers’ and psychologists’ intuitions about the format of mental imagery vary as a result of the vividness of their mental imagery. The results showed that the vividness of imagery has significant impact on theoretical commitments in this debate (Reisberg 2003). Researchers with less vivid mental imagery were more likely to take the propositional side and those with more vivid mental imagery tended to come down on the iconic side.
