Basic Principles of Dual Coding Theory book
DCT developed through research in which experimental procedures and hypotheses were progressively modified and extended to new cognitive domains. For example, the rhyme mnemonic technique evolved into standard laboratory tasks that isolated its effective components, and further extensions led to more general dual coding interpretations of memory and other cognitive phenomena. The survivors of this conceptual evolution consist of a series of interrelated assumptions and hypotheses that define DCT (e.g., Paivio, 1971b, 1986, 1991a, 1991b; Sadoski & Paivio, 2001), This chapter offers an updated version of the theory and its empirical implications. Detailed discussion of the relevant research is postponed to the next chapter, where the emphasis is on aspects that are especially pertinent to interpretations of cognitive evolution.
