Unifying psychological and biological approaches to understanding animal cognition.

This special issue has two main aims. The first aim is to broaden the scope of the Canadian Journal of Experimental Psychology. This aim is motivated by the simple fact that the journal's mandate includes comparative psychology, but many of the articles published in the journal are currently, and have been for some time, mainly human cognitive in nature. The second aim of this issue is one that we take very seriously, and that is to promote not only comparative cognition and cognitive ecology research but research from a diverse group of scientists. Although the global diversity in this special issue is not exhaustive, there is work highlighted from scientists at institutions in Canada, Germany, Italy, the Netherlands, Spain, the United Kingdom, and the United States.
