    Reading Faces

    Facial expressions can convey emotional nuances that words fail to communicate. Researcher Terrence Sejnowski has developed a computer program that analyzes images of human faces, purportedly matching the skills of professionals trained to read fleeting expressions of emotion. Learn more in an online article from the Howard Hughes Medical Institute’s HHMI Bulletin and at the […]
