Subtle Expression Recognition Training

Use the Matsumoto Method to learn Subtle Expressions

Created by Dr. David Matsumoto and Dr. Hyi Sung Hwang, Humintell’s SubX Subtle Expression Training courses were originally funded by and developed for US government agencies. Subtle expressions are often very difficult to see because they’re of low intensity. Recent research suggests that the ability to detect subtle expressions may be especially important for detecting deception, or for just learning to see the signs of concealed emotions.

All trainings have no time limit and are accessible 24 hours a day, 7 days a week through our training website. All licenses expire 1 year from date of purchase. Simply purchase the training, create an account and register your product key that you receive via email. It’s that simple.

How is our training different than SETT?

SubX features a baseline test, 13 instructional videos, a practice test with 70 color images and a post test. SETT features no baseline or post test and contains only 37 practice images in black and white.

SubX features instructional videos complete with full video and audio capabilities whereas SETT training contains only written verbiage.

SubX also contains better images-representing multiple ethnicities, genders and age groups whereas SETT features images from only one individual.

SubX contains an instructional video on how to identify expressions when portions of the face are hidden or covered. SETT does not contain this feature.

SubX training was developed for and funded by top governmental agencies in the United States.
