In experiments 2 and 3, they should discriminate between upright and inverted faces (in experiment 2, stimuli were faces with neutral or fearful expressions, while in experiment 3, stimuli were famous or unfamiliar faces).
In experiment 1, they should indicate whether the stimulus was either a face or a house or a scrambled image. Participants performed different tasks following the stimulus presentation. Eight healthy participants were tested as a control group. To address the involvement of these higher processes, we investigated event-related potential (ERP) neural correlates of faces in a patient with AD showing a face recognition deficit. However, it has been hypothesized that failure in identifying familiar people could also be due to deficits in higher-level perceptual processes, since there is evidence showing a reduced inversion effect for faces but not for cars in AD. 4Centro de Investigacion en Ciencias Cognitivas, Universidad Autonoma del Estado de Morelos, Cuernavaca, Mexicoįace recognition deficits are frequently reported in Alzheimer's disease (AD) and often attributed to memory impairment.3Center for Cognitive Decline and Dementia, ULSS 9 Scaligera, Verona, Italy.2Department of Neuroscience, Biomedicine and Movement Sciences, University of Verona, Verona, Italy.
