Waites, a psychologist, provides numerous useful references about infantile memory, starting with the example of Helen Keller who retrieved at age six memories about the word "water," which she had learned before she lost her hearing at age 19 months. It was this recovery of an infantile memory trace—taking place, as it so often does, within a sensorimotor reenactment as Helen Keller touched the water—that reopened the doors of language to her. We learn about other children who were able to narrate traumatic events that occurred before they were able to speak, and we learn that six-month-olds remember for 15 to 16 days. Certainly, the developmental rearrangement of memory organization at ages four to six confounds retrieval for much of the episodic aspects of these infantile memories, but all these processes are much more variable than the most dogmatic of the memory skeptics would have us believe.
