Imagery Mediation in Learning and Memory
This chapter focuses on experimental evidence and conclusions from studies that have been concerned specifically with imagery as a mediator in learning and memory tasks. Some of the studies simply provide experimental confirmation that imagery mnemonic techniques can be extraordinarily effective, as the proponents of such systems have claimed over the centuries (see Chapter 6). Others provide evidence bearing on certain assumptions and precepts associated with those systems, such as the rule that mnemonic images should be novel or bizarre and the assumption that the same memory loci can be used over and over again without interfering effects. Certain findings also provide a hint that the memory information in mediating images is organized in a spatially parallel form, as distinguished from the sequential characteristic attributed to verbal mediators. Generally, however, the studies reviewed in this chapter were not designed to distinguish the two postulated systems. That task is reserved for the next chapter.
