Acta Comportamentalia is published three times a year (March, June, and December) by the Editorial Department of the University of Guadalajara (Mexico). It is an international journal that publishes original manuscripts on behavior analysis written in one of the main Romance languages: Spanish, Portuguese, French, and Italian. This journal is intended as a high-quality scientific forum that allows the expression of Latin cultures’ tradition, originality, and innovation as a means to broaden the perspective of an area which so far has been built under a pragmatic, anglophile standpoint.
