ABSTRACT
This chapter deals with the unexpected and surprisingly broad role of self-produced experience in generating a number of crucial developmental changes in infancy. It has several objectives: to describe important developmental transitions that occur in several psychological domains in the second half-year of life, to specify the converging research operations that are used to demonstrate that experience locomoting is a catalyst for these developmental changes, and to propose the processes through which experience facilitates these transitions. Throughout the chapter, we stress the role of attention as an important index and mediator of infant development.
