“…Consistent with the idea that the N170 represents a crucial early stage of face processing, McPartland et al (2004) found a positive correlation between N170 latency and face identification deficits among individuals with ASD [128]. In a separate study of children with ASD (ages 3-4) compared to controls, Dawson et al (2002) found atypical modulation of late potentials in response to repeated presentation of a familiar versus an unfamiliar face in children with ASD [129].…”

Autism is a pervasive developmental condition, characterized by impairments in non-verbal communication, social relationships and stereotypical patterns of behavior. A large body of evidence suggests that several aspects of face processing are impaired in autism, including anomalies in gaze processing, memory for facial identity and recognition of facial expressions of emotion. In search of neural markers of anomalous face processing in autism, much interest has focused on a network of brain regions that are implicated in social cognition and face processing. In this review, we will focus on three such regions, namely the STS for its role in processing gaze and facial movements, the FFA in face detection and identification and the amygdala in processing facial expressions of emotion. Much evidence suggests that a better understanding of the normal development of these specialized regions is essential for discovering the neural bases of face processing anomalies in autism. Thus, we will also examine the available literature on the normal development of face processing. Key unknowns in this research area are the neuro-developmental processes, the role of experience and the interactions among components of the face processing system in shaping each of the specialized regions for processing faces during normal development and in autism.

“…Findings from electrophysiological studies have indicated that individuals with autism exhibit atypical event-related brain potentials to faces, characterised by an absent or reduced N170 waveform component (the event-related potential marker for faces), with a more bilateral rather than right lateralized voltage distribution (Dawson, et al, 2002;McPartland et al, 2004).…”

“…The N170 is maximal over posterior temporal areas (typically measured at electrodes T5 and T6), peaks at about 170 ms after stimulus onset, is faster and larger to face stimuli compared to non-face stimuli, and does not differ based on the familiarity of the face (Bentin, Deouell, & Soroker, 1999;Eimer, 2000). In a recent report, McPartland, Dawson, Webb, Carver, & Panagiotides, (2004) found that individuals with autism displayed slower N170 response to faces than to furniture and failed to show a face inversion effect, which in typical adults is characterized by a slower N170 to inverted than upright faces. Taylor, McCarthy, Saliba, and Degiovanni (1999) and Taylor, Edmonds, McCarthy, and Allison (2001) have identified a precursor to the adult N170, referred to here as the "precursor N170" in children between 4 and 15 years of age.…”

Autism involves a basic impairment in social cognition. This study investigated early stage face processing in young children with autism by examining the face-sensitive early negative eventrelated brain potential component in 3-4 year old children with autism spectrum disorder (ASD), typical development, and developmental delay. Results indicated that children with ASD showed a slower electrical brain response to faces and a larger amplitude response to objects compared to children with typical development and developmental delay. These findings indicate that children with ASD have a disordered pattern of brain responses to faces and objects at an early age.
