“…In one patient with selective PP, Evans et al (1995) interpreted their patient'spi ct ur e as due to a visual, modality-selective, inability to access personbased semantic knowledge; however, the patient eventually developed (over 9 months) a multi-modal loss of person-based knowledge. Evans et al's patient showed prominent right hemisphere temporal lobe atrophy; analogous lesions were reported in further patients with PP who were affected by analogous multi-modal deficits of person (and face) recognition, not restricted to the visual modality (Barbarotto et al, 1995;Gainotti, 2003;Gentileschi et al, 1999Gentileschi et al, , 2001.…”

“…presented with severe prosopagnosia, along with mild visual associative agnosia, with no relevant low-level visuospatial or semantic deficits. Previously reported cases of PP showed other visuoperceptual deficits or impairments in other cognitive domains (De Renzi, 1986;Tyrrell et al, 1990) or presented a multi-modal loss of personbased semantic knowledge not restricted to the visual modality (Evans et al, 1995;Barbarotto et al, 1995;Gentileschi et al, 1999Gentileschi et al, , 2001Gainotti, 2003). All these patients presented with anterior temporal lobe atrophy.…”

“…In a few studies, prosopagnosia has been described as the main manifestation of a neurodegenerative disorder (Barbarotto et al, 1995;De Renzi, 1986;Evans et al, 1995;Gentileschi et al, 1999Gentileschi et al, , 2001Gainotti, 2003;Tyrrell et al, 1990). Early patients with progressive prosopagnosia (PP) also showed visual agnosia, basic visuoperceptual deficits and impairments in other cognitive domains, associated with posterior cortical atrophy (De Renzi, 1986;Tyrrell et al, 1990).…”

Diffusion tensor imaging was performed to elucidate structural connectivity of the inferior longitudinal fasciculus (ILF) and the inferior fronto-occipital fasciculus (IFOF), the two major tracts that project through the core fusiform region to the anterior temporal and frontal cortices, respectively. Right ILF was markedly reduced in G.S., while left ILF and IFOFs were apparently preserved. These data are in favour of a crucial role of the neural circuit subserved by right ILF in the pathogenesis of PP.

“…2 In 22 of these cases, unfamiliar face recognition was tested only with the BFRT and/or the RMF [4,5,9,12,16,[17][18][19][20]23,28,30,35,36,47,48]. Because we have demonstrated that normal scores on these tests do not require intact unfamiliar face recognition, these cases should no longer be considered support for the dissociation.…”

An evaluation of two commonly used tests of unfamiliar face recognition

The Warrington Recognition Memory for Faces (RMF) and the Benton Facial Recognition Test (BFRT) are commercially available tests that are commonly used by clinicians and cognitive neuropsychologists to evaluate unfamiliar face recognition. Yet, it is not clear that a normal score on either instrument demonstrates normal unfamiliar face recognition. Because the RMFs stimuli contain abundant non-internal facial feature information, subjects may be able to score in the normal range without using internal facial features. On the BFRT, subjects commonly rely on feature matching strategies using the hairline and eyebrows rather than recognizing the facial configuration. To test whether these routes to recognition can support normal performance, normal subjects were tested with versions of the RMF and the BFRT in which the faces had been painted over in a way that prevented the operation of some of the procedures normally involved with face recognition. Even though these modifications removed all of the internal feature information in the RMF, many subjects scored in the normal range, and despite precluding the use of configural processing in the BFRT, many of the scores were in the normal range. As a result, it is apparent that normal scores on these tests do not demonstrate normal unfamiliar face recognition and so clinicians should be cautious in interpreting scores in the normal range. Finally, these results place in question models supported by dissociations involving normal performance on these tests.

“…In several neuropsychological case studies, the right temporal lobe has been implicated as a critical locus for knowledge of people (Ellis, Young, & Critchley, 1989;Evans, Heggs, Antoun, & Hodges, 1995;Gentileschi,Sperber, & Spinnler, 1999;Hanley, Young, & Pearson, 1989;Kitchener & Hodges, 1999), although other studies suggest that left-sided damage can also result in similar, albeit milder, deficits (Eslinger, 1998;. In a recent investigation, Thompson, Graham, Patterson, and Hodges (2003) assessed 12 patients with semantic dementia on a battery of tests requiring access to semantic knowledge about either familiar objects or famous people.…”
