“…No active learning of faces was required in our experiment, but it is possible that automatic memorization was triggered for intact faces and failed for distorted ones. Evidence for automatic encoding exists; an increased parietal positivity is seen for previously viewed faces (Paller et al, 2000) under explicit, but also under implicit, conditions (Münte et al, 1998).…”

Abstract& Most studies on visual perception of human beings have focused on perception of faces. However, bodies are another important visual element, which help us to identify a member of our species in the visual scene. In order to study whether similar configural information processing is used in body and face perception, we recorded high-density evenrelated potentials (ERPs) to normal and distorted faces and bodies in adults and 3-month-old infants. In adults, the N1 responses evoked by bodies and faces were similar in amplitude but differed slightly in latency. The voltage topography of N1 also differed in concordance with fMRI data showing that two distinct areas are involved in face and body perception.Distortion affected ERPs to faces and bodies similarly from N1 on, although the effect was significant earlier for bodies than for faces. These results suggest that fast processing of configural information is not specific to faces but it also occurs for bodies. In 3-month-old infants, distortion decreased the amplitude of P400 around 450 msec, showing no interaction with image category. This result demonstrates that infants are not only able to recognize the normal configuration of faces, but also that of bodies. This could either be related to an innate knowledge of this particular type of biological object, or to fast learning through intense exposure during the first months of life. &

“…Possibly marking the category-recognition stage, the N170 is sensitive to features usually predictive of faces, such as isolated eyes, nose or mouth [117,118], or back views of the head, or face outlines without features. In contrast, the N170 appears independent of face identity [113,119,120] as it is insensitive to face repetition [119,121], learning [122], familiarity [123,124], or attention [125]. Although the N170 is not dynamically responsive to face identity or memory, comparison among adult subjects suggests that its amplitude and latency may predict general proficiency at face recognition [114].…”

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.

“…The late positive component (P300/LPC), occurring between~300 and 1000 msec, also shows an increase to familiar items compared with novel items (Henson et al, 2003;Münte et al, 1997;Schweinberger et al, 1995;Bentin & McCarthy, 1994;Barrett et al, 1988). The LPC effect is largest over centroparietal electrode sites and its magnitude varies with task parameters (Paller et al, 2003;Paller & Gross, 1998), the relative familiarity of the stimulus (Henson et al, 2003;Münte et al, 1997;Schweinberger et al, 1995;Bentin & McCarthy, 1994;Barrett et al, 1988), and the delay between item repetitions (Rugg & Nagy, 1989), among other factors.…”

The repetition effect for unfamiliar faces is smaller than that to well known (famous/family) faces (Münte et al, 1997;Schweinberger et al, 1995;Bentin & McCarthy, 1994;Barrett et al, 1988;see Henson et al, 2003, for equivalent repetition effects). Furthermore, although the LPC difference between ERPs to new and repeated items is on the order of~2.5-8 AV in explicit tasks, it is about half the size,~1 and 4 AV, in implicit tasks (Paller et al, 2003;Paller & Gross, 1998).…”

Abstract& Electrophysiological studies have investigated the nature of face recognition in a variety of paradigms; some have contrasted famous and novel faces in explicit memory paradigms, others have repeated faces to examine implicit memory/ priming. If the general finding that implicit memory can last for up to several months also holds for novel faces, a reliable measure of it could have practical application for eyewitness testimony, given that explicit measures of eyewitness memory have at times proven fallible. The current study aimed to determine whether indirect behavioral and electrophysiological measures might yield reliable estimates of face memory over longer intervals than have typically been obtained with priming manipulations. Participants were shown 192 faces and then tested for recognition at four test delays ranging from immediately up to 1 week later. Three event-related brain potential components (e.g., N250r, N400f, and LPC) varied with memory measures although only the N250r varied regardless of explicit recognition, that is, with both repetition and recognition. &
