According to many ethologists, the vast majority of linguistic properties and features are not uniquely human, but do exist in nonhuman animals as well. Very recently, Ouattara, et al. (2009) have broadened the range of language properties which are supposedly shared by nonhuman organisms: they have claimed that a species of Old World monkeys is endowed with a morphology-like behavior. Our paper has two main objectives: firstly, we aim at critically discussing Ouattara's claim by showing that the behavior shown by Campbell monkeys has nothing to do with true morphology, if morphology is rigorously considered. Secondly, and more generally, we critically analyze the strategy of attributing linguistic behaviors to animals, which has pervaded ethological studies. [ABSTRACT FROM AUTHOR]

Radical Behaviorism, whose most important exponent was B. F. Skinner, is often misunderstood and criticized in academic and non academic circles. Different cultural, ideological and politic factors help to contribute to this attitude. The present paper offers a panoramic view of the most controversial issues about this theory and some of its critics. The aim is to discuss some of the ideas or hypothesis that psychology has assumed as certainties without any questioning, considering that a debate on this ideas could contribute to the development of this science.
