Although much of the research on implicit memory involves the study of indi­ vidual words, a parallel literature has evolved in the study of text processing. Paul Kolers’ work on memory for messages read in transformed typographies provided the intellectual lead. This chapter traces the development of research that followed Kolers in using transfer measures as a way to explore memorial representations. The studies investigated how prior reading of a message influ­ enced the subsequent reading of that message. In other words, what remained in memory following a reading encounter that facilitated the rereading of that message? The procedure opens a window for exploring the ways in which prac­ tice or experiences can influence the development of reading skill.
