– For example: the chimp knew where the key was but also knew the experimenter
didn't so pointed it out.
"Theory of mind" Are animals aware of themselves and those
around them? 8 Consciousness, Self-Awareness, and
the Brain 9 3 The right hemisphere may be linked to self awareness What neural mechanisms subserve the
process of self-awareness?
The right hemisphere may
selectively participate in
processes linked to selfawareness
What’s the evidence?

Neurology: Self-recognition and the right hemisphere
Julian Paul Keenan, Aaron Nelson, Margaret O'Connor and Alvaro PascualLeone, Nature 409, 305(18 January 2001) > Involves anaesthetization (inactivation) of one side of the braing Studied a group of patients
undergoing the intracarotid
amobarbital (Wada) test.
The Wada test involves
anaesthetization (that is,
inactivation) of one cerebral
hemisphere in order to
provide information regarding
cerebral dominance. 11 Study Design
Five right-handed (left hemisphere is language-dominant)
patients were shown pictures of faces generated by morphing
the picture of a famous person with the patient's own face. > Right handed ( left hemisphere) shown pictures of faces mixed with their

Different pictures were presented during selective anaesthesia
