Paragraph 2
In the study, 17 volunteers looked at
false and human faces. They rated the
of emotion they felt upon seeing
one. The researchers said the same
processing was involved in deciding what was or wasn't a
face. Researcher David Alais said: "We know these objects are not
faces, yet the perception of a face lingers." He said our
sees two things at once, and that we focus more on the
of a face than the object. He added: "The
impression of a face does not give way to the second
of an object."
