Japanese high school students were glued to the screen as a Harvard University student, acting as teacher, clicked on the computer and fused photographs of people's faces, claiming she could create a face people would find attractive.

"Maybe," one high school student said when asked if he thought the face was attractive. "Hard to say," said another, who wasn't as easily convinced.

The presentation, titled "Psychology of Love," is part of a program in which 20 Harvard students lecture to about 80 Japanese high school students in seminars based on those at the prestigious Ivy League institution, the first of their kind in Tokyo.
