“…View-centered descriptions provide information for the analysis of expression, whereas abstract, expression-independent descriptions provide information for the analysis of identity. This parallel processing model has generally been supported by the results of early neurobiological studies (for a critical view, see Tiberghien, Baudouin, Guillame, & Montoute, 2003). Neuropsychological studies showed that some prosopagnosic patients with an impairment in face recognition also exhibited a relatively preserved ability to recognize emotional expressions, whereas other patients presented the reverse pattern of performance (e.g., Humphreys, Donnelly, & Riddoch, 1993).…”

Asymmetrical interactions in the perception of face identity and emotional expression are not unique to the primate visual system

The human visual system appears to process the identity of faces separately from their emotional expression, whereas the human visual system does not appear to process emotional expression separately from identity. All current explanations of this visual processing asymmetry implicitly assume that it arises because of the organization of a specialized human face perception system. A second possibility is that this finding reflects general principles of perceptual processing. Studying animals that are unlikely to have evolved a specialized face perception system may shed fresh light on this issue. We report two experiments that investigated the interaction of identity and emotional expression in pigeons' perception of human faces. Experiment 1 found that pigeons perceive the similarity among faces sharing identity and emotion, and that these two dimensions are integral according to a spatial model of generalization. Experiment 2 found that pigeons' discrimination of emotion was reliably affected by irrelevant variations in identity, whereas pigeons' discrimination of identity was not reliably affected by irrelevant variations in emotion. Thus, the asymmetry previously reported in human studies was reproduced in our pigeon study. These results challenge the view that a specialized human face perception system must underlie this effect.

“…In the present case, we suggest thatthere is a difference in theway facial features can be used to makecontrasting judgements, but there is not necessarily a differencebetween processing facial identity and emotion. A failure todemonstrate qualitative similarities between a residual ability ina patient and the normal process in controls means that it is possibleto challenge the view that two distinct and/or independentregions sustain identity and emotion processing (e.g., Baudouin,Martin, Tiberghien, Verlut, & Franck, 2002;Ganel& Goshen-Gottstein, 2004;Martin, Baudouin, Tiberghien,&Franck, 2005;Schweinberger, Burton, & Kelly, 1999;Tiberghien, Baudouin,Guillaume, &Montoute, 2003).…”

Compensatory strategies in processing facial emotions: Evidence from prosopagnosia

We report data on the processing of facial emotion in a prosopagnosic patient (H.J.A.). H.J.A. was relatively accurate at discriminating happy from angry upright faces, but he performed at chance when the faces were inverted. Furthermore, with upright faces there was no configural interference effect on emotion judgements, when face parts expressing different emotions were aligned to express a new emergent emotion. We propose that H.J.A.'s emotion judgements relied on local rather than on configural information, and this local information was disrupted by inversion. A compensatory strategy, based on processing local face parts, can be sufficient to process at least some facial emotions.

A detailed investigation of facial expression processing in congenital prosopagnosia as compared to acquired prosopagnosia

Whether the ability to recognize facial expression can be preserved in the absence of the recognition of facial identity remains controversial. The current study reports the results of a detailed investigation of facial expression recognition in three congenital prosopagnosic (CP) participants, in comparison with two patients with acquired prosopagnosia (AP) and a large group of 30 neurologically normal participants, including individually age- and gender-matched controls. Participants completed a fine-grained expression recognition paradigm requiring a six-alternative forced-choice response to continua of morphs of six different basic facial expressions (e.g. happiness and surprise). Accuracy, sensitivity and reaction times were measured. The performance of all three CP individuals was indistinguishable from that of controls, even for the most subtle expressions. In contrast, both individuals with AP displayed pronounced difficulties with the majority of expressions. The results from the CP participants attest to the dissociability of the processing of facial identity and of facial expression. Whether this remarkably good expression recognition is achieved through normal, or compensatory, mechanisms remains to be determined. Either way, this normal level of performance does not extend to include facial identity.
