Second Day

After the completion of the workshop-group discussions in the morning of the second day, the meeting continued in the afternoon with a further plenary session, this time chaired by Prof. R. Wallerstein, and with a panel consisting of Dr Prof. D. Cohen, Dr A. Kris and Prof. J. Sandler. Following the panellists' contributions, the Chairman invited a discussion from the floor. The Colloquium ended with the Chairman's final summing up.

R. Wallerstein: We have made some changes this year in the format of the last session which you will recognize. We are not having the usual reports from the panels that have characterized the second afternoon sessions in previous years; instead we had a meeting of the chair people of the groups earlier today and I hope to include the highlights of what they brought into the talk that I will give later. The panel in this first half of the afternoon consists of three speakers, but they will not be reporting on the discussion in their specific groups except insofar it adds to their own general perspectives on the symposium as a whole. So these will be three quite different and quite personal statements reflecting the panellists' thoughts and do not claim to represent the discussions within their group. This will give them additional leeway and flexibility. I will now just call upon them in alphabetical order.

D. Cohen: I will make several brief points which may return in the discussion.

The topic that we are discussing is obviously extremely complicated. The two papers have taken, I think, quite different and in some ways more provocative points of view than appears on their surface. The paper prepared by George Moran and his colleagues seems like a simple, straightforward exposition but contains important and dramatic propositions. Conceptual problems are faced in reading these two papers. These stem primarily from the concepts of development and developmental disorders; these concepts are relied on heavily.
