Profiles of cognitive precursors to reading acquisition. Contributions to a developmental perspective of adult literacy

This article discusses conceptual and empirical elements concerning the development of cognitive processes that function as precursors of reading, and their association with the acquisition of reading skills in an adult population participating in literacy courses. It connects emergent literacy research with historical–cultural and bioecological concepts. Subsequently, it focuses on the problem of the development of profiles of cognitive reading precursors. A sample of 63 Chilean adults was studied through a growth/learning curves approach. The study replicated previous results indicating the existence of three major profiles of these cognitive precursors. Together, these precursors are associated with significantly different learning curves beyond the effect of each precursor considered separately. In addition, it established a negative association between initial phonological awareness and the rate of reading acquisition during the course. It has been claimed that an individual's participation in specific cultural activities throughout his/her life influences the development of the precursors of reading. Based on a complementary biographical study of a subsample of participants, preliminary evidence is presented that supports this link.

► We replicated the existence of three profiles of cognitive precursors of reading.
► These profiles are associated with different reading learning curves, in adults.
► Profiles explain more variance than the additive effect of cognitive precursors.
► These profiles are associated with formal and non-formal cultural experiences.
