Paragraph 2
In the study, 17 volunteers looked at a
of illusory and human faces. They had to rate the
of emotional attachment they felt upon seeing each one. The researchers'
was that the same neural
was involved in determining what was or wasn't a real
. Psychologist David Alais said: "We know these objects are not truly faces, yet the
of a face lingers." He added: "We end up with...a
experience that the object is both a
face and an object." Mr Alais said the brain sees two things at once, and that we focus more on the image of a face than the
it is an object. He added: "The first impression of a face does not give way to the
perception of an object."
