ABSTRACT
The basic foundations of psychological research are analyzed from a systematic and historical point of view. The conceptual frame of reference of contemporary psychology—both in its biological and in its social end—is considered. Current criticisms to experimental methodology are presented and refuted. Experimental psychology has contributed to a better understanding of behavioral issues and has a number of applications. The research program carried out by the author on early learning and psychological development is presented as an example of cross-cultural investigation. An international perspective shows that social and political factors influence the main trends in research. The most important trends that will define the future of psychology are analyzed.
