Escalona-Heider-Kagan

Comments on the book review by Jerome Kagan (see record 200606020-011) on the book Prediction and Outcome: A Study in Child Development by Grace Heider and Sibylle K. Escalona (1959). The author states that he was astonished to read that the contamination between prediction and evaluation of outcome could have been avoided. In many cases, groups of predictions were so similarily phrased that if one proved valid, so must the second Some statements were the most likely outcomes for any child in this culture. The reason was that he had written something like this more than two years ago after seeing rough drafts of original chapters and then the authors, with the help of the staff of the Coping Project, had gone ahead to meet these objections.
