ERP studies of face processing in developmental prosopagnosia:
Neuropsychological and neurodevelopmental perspectives
People with developmental prosopagnosia (DP) show severe face
recognition deficits that typically emerge in early childhood, without
history of neurological damage. I will present and discuss recent
findings from ERP studies of face perception and face recognition in DP.
The generic face-sensitivity of the N170 component is preserved in most
DPs, suggesting intact rapid detection of face components. In contrast,
DPs show atypical N170 face inversion effects, indicative of impaired
configural face processing. In line with a neurodevelopmental
interpretation of DP, these effects are similar to those observed for
other developmental disorders, and during earlier stages of typical
development. Identity-sensitive ERP components (N250, P600f) that are
markers of successful face recognition are very similar for DPs and
control participants, indicating that some aspects of the core face
processing network operate normally in DP. However, there is a distinct
sub-group of DPs which shows covert face recognition effects for the
N250 component, indicating that visual face memory is intact but is
disconnected from semantic memory in these individuals. I will discuss
the implications of these findings for neuropsychological and
neurodevelopmental perspectives on DP.
We're looking forward to see you there (Frankel Leo u. 30-34) !
