MISSION STATEMENT :
The Mexican Journal of Behavior Analysis (MJBA, ISSN-0187-4534) is published three times per year (June, September and December) by the Mexican Society of Behavior Analysis. The MJBA publishes original basic or applied research reports relevant to the behavior of animals or humans. Review or theoretical articles are also considered for publication. While both, the June and December issues include diverse papers submitted for publication, the September, special issue, focuses on a single topic. The MJBA publishes papers in either, Spanish or English and include abstracts in both languages. English abstracts of papers published in MJBA appear in the indexes of the American Psychological Association, Psychological Abstracts, PsycINFO and PsycLIT.
MJBA POLICIES
Manuscripts submitted to MJBA should conform to the standard style described in the Publication Manual of the American Psychological Association. With the exception of invited articles, each newly received manuscript is assigned to a particular Associate Editor, who then, in turn sends the paper for review to at least two members of the Editorial Board. The usual publication lag ranges from six months to a year. Manuscripts submitted for publication should be sent to Carlos A. Bruner, Editor MJBA, Apartado Postal 70/693, Ciudad Universitaria, Mexico D. F. 04510, MEXICO. Email bruner @ servidor.unam.mx .
