“…Human neuroimaging studies report both view-selective as well as partial viewinvariant representation up to 30 -60°for different object categories (James et al, 2002;Vuilleumier et al, 2002;Andresen et al, 2009). Most functional magnetic resonance imaging (fMRI) studies with faces report view selectivity for unfamiliar faces (Grill-Spector et al, 1999;Andrews and Ewbank, 2004), with partial view-invariant representation up to 20 -30°for familiar faces (Eger et al, 2004;Pourtois et al, 2005;Ewbank and Andrews, 2008). These findings are consistent with behavioral studies showing better recognition of faces that were previously seen in the same or adjacent views (Hill and Bruce, 1996;Fang and He, 2005).…”

“…Most of these studies revealed release from adaptation for different views of faces and objects (Gauthier et al, 2002;Andrews and Ewbank, 2004;Fang et al, 2007;Xu et al, 2009). Other fMR-adaptation studies revealed a moderate invariance for view (view differences of up to 30°) for familiar (celebrity) faces (Eger et al, 2005; Pour- Ewbank and Andrews, 2008), objects (James et al, 2002;Vuilleumier et al, 2002;Andresen et al, 2009), and bodies (Taylor et al, 2010). In line with these findings, a recent MVPA study revealed both view-specific and view-invariant representation for objects differing in 60°in the LOC (Eger et al, 2008).…”

The ability to recognize objects across different viewpoints (view invariance) is a remarkable property of the primate visual system. According to a prominent theory, view information is represented by view-selective mechanisms at early stages of visual processing and gradually becomes view invariant in high-level visual areas. Single-cell recording studies have also reported an intermediate step of partial view invariance for mirror-symmetric face views. Nevertheless, similar evidence for this type of hierarchical processing for face view has not been reported yet in the human visual cortex. The present functional magnetic resonance imaging study used state-of-the-art multivariate pattern analysis to explore face-view tuning in the human visual cortex. Our results revealed that consistent with a viewselective representation, face view can be successfully decoded in face and object-selective regions as well as in early visual cortex. Critically, similar neural representations for mirror-symmetric views were found in high-level but not in low-level visual areas. Our results support the notion of gradual emergence of view-invariant representation with invariance for mirror-symmetric images as an intermediate step and propose putative neural correlates of mirror-image confusion in the human brain.

“…Functional magnetic resonance imaging (fMRI) adaptation (fMRI-A) reveals reduced responses in ventral face-selective regions to identical faces than to different faces (Grill-Spector et al, 1999;Grill-Spector and Malach, 2001;Avidan et al, 2002;Winston et al, 2004;Ewbank and Andrews, 2008). Notably, the level of fMRI-A depends on the similarity among faces.…”

Development of Neural Sensitivity to Face Identity Correlates with Perceptual Discriminability

Face perception is subserved by a series of face-selective regions in the human ventral stream, which undergo prolonged development from childhood to adulthood. However, it is unknown how neural development of these regions relates to the development of faceperception abilities. Here, we used functional magnetic resonance imaging (fMRI) to measure brain responses of ventral occipitotemporal regions in children (ages, 5-12 years) and adults (ages, 19 -34 years) when they viewed faces that parametrically varied in dissimilarity. Since similar faces generate lower responses than dissimilar faces due to fMRI adaptation, this design objectively evaluates neural sensitivity to face identity across development. Additionally, a subset of subjects participated in a behavioral experiment to assess perceptual discriminability of face identity. Our data reveal three main findings: (1) neural sensitivity to face identity increases with age in face-selective but not object-selective regions; (2) the amplitude of responses to faces increases with age in both face-selective and object-selective regions; and (3) perceptual discriminability of face identity is correlated with the neural sensitivity to face identity of face-selective regions. In contrast, perceptual discriminability is not correlated with the amplitude of response in face-selective regions or of responses of object-selective regions. These data suggest that developmental increases in neural sensitivity to face identity in faceselective regions improve perceptual discriminability of faces. Our findings significantly advance the understanding of the neural mechanisms of development of face perception and open new avenues for using fMRI adaptation to study the neural development of high-level visual and cognitive functions more broadly.

“…Neuroimaging studies have highlighted how each of these areas show differential responses for correct versus incorrect face recognition and for familiar compared with unfamiliar faces processing [19][20][21] . In addition, these areas have been shown to respond, to a certain degree, to faces regardless of the viewpoint from which they are being perceived 22,23 . This evidence highlights these regions as candidate areas for updating the familiarity of faces and processing contextual information about how familiar a face is likely to be.…”

Face recognition is a key component of successful social behaviour. However, the computational processes that underpin perceptual learning and recognition as faces transition from unfamiliar to familiar are poorly understood. In predictive coding, learning occurs through prediction errors that update stimulus familiarity, but recognition is a function of both stimulus and contextual familiarity. Here we show that behavioural responses on a two-option face recognition task can be predicted by the level of contextual and facial familiarity in a computational model derived from predictive-coding principles. Using fMRI, we show that activity in the superior temporal sulcus varies with the contextual familiarity in the model, whereas activity in the fusiform face area covaries with the prediction error parameter that updated facial familiarity. Our results characterize the key computations underpinning the perceptual learning of faces, highlighting that the functional properties of face-processing areas conform to the principles of predictive coding.
