Piagetian object-permanence in Cebus capucinus, Lagothrica flavicauda and Pan troglodytes

Object-permanence was studied with one chimpanzee (Pan troglodytes) and two New World monkeys (Lagothrica flavicauda and Cebus capucinus). The chimpanzee and the capucinus attained stage VI, while Lagothrica reached stage Va. The data show that tests of object-permanence are suitable for comparison among species. This study also attempts to propose an experimental scheme that could allow for a more valid comparison among species. Use of an operant conditioning procedure is suggested and discussed.

The directive sex therapies in psychiatric outpatient settings.

The treatment techniques and associated outcome studies of the directive sex therapies (DST) are briefly reviewed and data on the treatment of 12 couples are presented. The directive sex therapies have achieved rather impressive results but only with highly selected populations. Studies, such as the present, with a range of patients more typical of psychiatric outpatient settings have consistently achieved lower success rates. The important effect of patient selection on outcome with DST has, to date, received little attention. The present authors discuss selection criteria for DST in the light of the literature and the outcome in their own cases.
