Face Recognition


“Which Face is Happier?”

Activity Instructions



There are three examples provided for this activity. Each example consists two
pictures of the same face. The face in each picture is ambiguous because one side is
“happy” and one side is
“sad.” Specifically, one of the pictures is “happy” on the left side
and “sad” on the right side, while the other picture is “happy” on the right side and “sad”
on the left side.


Give each student a copy of each example and ask which of the two pictures
in
each example looks “happier.” Take a class vote once on which of the two looks
happier. According to face recognition theory, more people will say that the picture with
the left side as “happy” will tend to look happier. Explain to the class why the maj
ority
thinks that the face with the left side as “happy” looks happier.

According to research studies, people use more of their right brain hemisphere to
recognize and process faces. As we all learned earlier this week, the right side of the
brain is conn
ected to and controls the left side of our body, including our eyes. Thus,
because we see the “happy” side of the face in our left visual field, we tend to think that
the overall picture looks “happy.” Inversely, when the “sad” side of the face is in our l
eft
visual field, we tend to think the overall picture looks more “sad.”
