The article presents proceedings of the Annual meeting of the Phycological Society of America at the University of Minnesota, Minneapolis, Minnesota, held between August 27-September 1, 1972. All sessions of the program at which contributed papers are presented were joint sessions of the Phycological Society of America and the Phycological Section of the Botanical Society of America. Various research papers were presented at the annual meeting. Section one was on Nuisance Algae and Bloom Phenomena. Section two was on Physiology and Biochemistry.

This research paper reports two small studies which form part of a series of exploratory investigations by the authors where the explicit aim has been to examine why some children respond differently to management techniques normally effective with most. A close association between scores on the Psychopathic Deviant Scale (Pd) of the Minnesota Multiphasic Personality Scale and teachers' assessments of refractory behavior suggest that such behavior could be considered as being on the same continuum as psychopathy and that the Pd Scale might prove a useful index of it. Early adverse experience was also found to be related to refractory behavior, as in psychopathy.

This paper reports one aspect of the Nobles County, Minnesota Mental Health Survey which has been underway since 1949. The general investigation had three main aims: (1) to undertake a study of the prediction of adjustment over time, (2) secure age data on personality and adjustment measures, and (3) develop screening instruments for locating children and adolescents in need of special attention. The first of these aims, the prediction of adjustment, is reported on here. The predictions cover a four year period and the results reported are for the men in the sample. The problems of the present prediction study can be reduced to (1) the development of predictors, (2) the development of criteria, and (3) the relation of predictors to criteria.

The article presents information on the norms for the Minnesota multiphasic personality inventory with student nurses. Clinical experience has indicated the need for special norms on the Minnesota Multiphasic Personality Inventory (MMPI) for college students and other groups such as student nurses. This paper presents MMPI T scores secured from a normative group of 168 student nurses. The scores of freshman student nurses did not differ significantly from those of the whole group.
