Project Description

This directory contains files from three children. The children are Peter, Eric, and Gia. Peter was born on December 27, 1969; Eric was born on July 2, 1964; and Gia was born on February 5, 1965. The files called “bookeric” and “bookgia” have the material reported in the book. The other files, beginning when Eric is 19 months old, have been entered from handwritten transcripts. Eric and Gia were studied in the context of the project reported upon in Bloom (1970). Additional data on hand-written sheets are available for Eric and Gia, as well as for a fourth child Kathryn.

The Peter subdirectory contains 20 files, recorded between 1971 and 1973 when Peter was between 1;9 and 3;2. Peter was an upper-middle class white child with college-educat-ed parents. He was a first-born child living in a university community in New York City. Digitized audio is available for most of the Peter files, but the following segments are missing: Peter8-Tape21, Peter10-Tape25/26, Peter14-Tape37, and Peter16-Tape43, Peter17-Tape45.
