Allan Urho Paivio, professor of psychology at the University of Western Ontario, is known internationally for his systematic theoretical and experimental account of the role of higher mental functions in human learning and memory. Educated at McGill University, his teaching and inspired research at the University of Western Ontario since 1962 have made him the world authority on non-verbal imagery and verbal processes as memory codes and mediators of behaviour. His numerous technical papers, scholarly addresses, and particularly his book "Imagery and Verbal Processes", represent an integration of prebehaviouristic and behaviouristic views concerning the nature of thought. Past President of the Canadian Psychological Association, he has enhanced immeasurably Canada's prestige in the scientific analysis of human behaviour.

LEO VICTOR PANITCH is Canada's pre-eminent contributor to the comparative analysis of corporatism in modern liberal democratic states. He ranks among the most distinguished political scientists in the world, and apart from the wide-ranging impact of his own published scholarship, his dynamic and creative organizational leadership has done much to promote the vitality of Canadian scholarship in political science and political economy. His scholarship has focussed on the parties and politics of labour, and the problems and prospects of social democracy. He has produced major monographs on British and Canadian politics, as well as numerous works of broader comparative and theoretical interest. He is internationally renowned for his original theoretical argument about the limitations of corporatism, and for his contribution to the development of a neo-Marxist theory of the state in capitalist societies.

Dennis Parkinson is one of Canada's outstanding soil scientists. He has added much to our knowledge of how fungi, the largest component in soil biomass and probably the most poorly understood, operate. He has devised ingenious new research techniques, written and taught eloquently and extensively on his chosen field, and built up one of the best Biology Departments in Canada.

A pioneer social historian, Joy Parr has made womens' history and the history of the family central concerns in her discipline. Her two major works, "Labouring Children" and "The Gender of Breadwinners", are at once scholarly works of great subtlety and power as well as touching, human documents that have reached a broad audience. Her scholarship has been recognized with the Canadian Historical Association's highest honour, the Macdonald Prize. Her essays and collections have reshaped Canadian history and helped connect it to an international literature on gender relations, economic change and the family.

Dr. Parsons initiated research in biological oceanography which has served as a basis for programs throughout the hydrosphere. In particular, his work on the chemical composition of organic particulate material in the sea, marine food chains and large-scale studies of the oceanic environment have led to a better understanding of natural processes governing the world's oceans. Dr. Parsons planned and initiated Canada's first Trans-Pacific research cruise and the first large-scale artificial fertilization of a lake (12,000 acres). He has been recognized as an invited speaker at a large number of academic institutions and was elected President of the American Society of Limnology and Oceanography in 1970.
