July 1971 saw the expansion of the Department of Psychology, integrating related disciplines to form the new Behavioral Sciences Department headed by Professor Exaltacion Ramos. The Experimental Psychology Laboratory was launched. On July 6, the University's Academic Council approved the proposal for a major in Behavioral Sciences, for implementation in School Year (SY) 1971 – 1972. May 1985 saw the development of a new curriculum for the Behavioral Sciences major program, emphasizing the three disciplines of sociology, anthropology, and psychology. In 1992, the Behavioral Science major program spun off to create the present Behavioral Sciences Department. June 1993 witnessed the launch of the post-graduate diploma and master's program in health social science.
