Document Summary
Summary: in this chapter we have examined mental imagery and its roles in cognitive processes such as perception, learning, and memory. Behind much current research in this area is the influential dual-coding theory of allan paivio. According to paivio, imagery is a non-verbal system by which we represent events as mental images. It exists alongside and often in reference to a verbal system of representation: the defining properties of mental images are concreteness, distinctiveness, and vividness. These properties support learning and memory by helping us to organize incoming information into meaningful units. Sometimes the common ability to form mental images take extraordinary forms, as with individuals who experience eidetic imagery or synesthesia. People with one common form of synesthesia associate particular letters or digits with particular colours: unlike static pictures, mental images are dynamic. They can be mentally rotated, moved, or scanned, often within an egocentric frame of reference.
