PSYCO258 Chapter Notes - Chapter 7: Chromesthesia, Eidetic Memory, Cognitive Map
Document Summary
This chapter examines mental imagery and how we invoke mental pictures or sounds in order to remember and think. An interesting example of this is seen in time-space synethesia, which is the case when people experience various units of time (e. g. , the months or days of the week) as a spatial pattern that only they can see. Paivio postulated the dual-coding theory, which argues that images can be represented by both verbal and non-verbal systems. Logogens are the units that are part of the first system, and imagens comprise the latter. Furthermore, paivio maintained that words that produce a mental im- age have concreteness. In one of his experiments a high correlation was found between ratings of high concreteness and high imagery. Imagery has also been used as a mnemonic technique, by employing the method of loci (us- ing bizarre images of objects placed in familiar places), for instance.
