ABSTRACT
In preparing this chart, an effort was made to select significant items in each of the stages while abiding within limits that would allow a comprehensive view of the field. This procedure was beset with frequent and persistent doubt as to what to include or omit. To alleviate the uneasiness arising from such difficult and inescapable decisions, I have added an appendix in which the reader may find, in tabular form, a fuller summary of the characteristic features of the several aspects of child development.
