Alfredo Villagracia Lagmay (August 14, 1919 –December 15, 2005) was a respected Filipino psychologist and Professor Emeritus of Psychology at the University of the Philippines Diliman.

He received his Ph.D. in psychology from Harvard University and trained under the psychologist and founder of the radical behaviorism movement B.F.

After a year, he worked with the Dean of Men's office and afterwards as a reception clerk to then UP President Bienvenido M. Gonzales.

After the war, he shifted to philosophy due to the lack of teachers in psychology at the time.

[4] Lagmay's researches include experimental analysis of behavior, relaxation, hypnosis, and other related studies.

It was entitled "The Pacing of Behavior: A Technique for the Control of the Free Operant" published in the Natural and Applied Science Bulletin.

Her paper lacks empirical data and this led Lagmay to make a thematic apperception test conducted with 15 participants from Metro Manila.
