Document Summary
Capgras delusion: a window on face recognition: ellis & lewis (2001) Research variables: skin conductance response (scr) tests: iv"s were the known and unknown faces that are shown. The dv"s were the amplitudes of the electric current. Brief experimental description: participants were given pictures of different faces and the resistances on the subjects" skin were measured. Then viewed results on behavioral and cognitive tests, such as name re-learning, face interference, and face-name priming. Main result: there was not a significant difference between amplitudes for familiar and unfamiliar faces for capgras subjects. Those who could not recognize faces were still able to successfully perform behavioral and cognitive tests. Implication: information from two loci behavioral/cognitive recognition, and autonomic recognition must join together in order to identify someone. Capgras syndrome in vascular dementia: recognition memory and visual processing: Research variables: ivs were the types of objects shown: inanimate, and animate.
