“…Faust, a contemporary of Bodamer, initially proposed that prosopagnosia reflects a general inability to grasp the detailed features of a stimulus so that its individuality is not appreciated , a claim supported by his observations of neurological patients who had difficulties distinguishing objects belonging to the same category, such as a chair versus an armchair (Faust, , ). Supporting this view, other reported prosopagnosic patients presented with difficulties recognizing specific foods and animals (Pallis, ), car brands (Macrae & Trolle, ), fruits (De Renzi, Faglioni, & Spinnler, ), horses (Newcombe, ), similar birds (Bornstein, ), or individual cows (Bornstein, Sroka, & Munitz, ) (see Barton & Corrow, for a longer list of such cases, and the discussion below).

“…(), but appears also in the anecdotal reports of Damasio et al . () on their patients’ recognition difficulties, or other reports as listed by Barton and Corrow (). Exactly how this deficit needs to be taken into account is unclear, but one could argue that to estimate the cost of increasing similarity between a target and a distractor, proportional increases of error rates and RTs should be considered with increasing levels of visual similarity rather than stable levels as in Gauthier et al .…”

“…It has been stated that proving that a patient does not have any problems at object recognition requires one to accept proof of the null hypothesis (Barton & Corrow, ; Ellis & Young, ). As I understand this, one would have to prove the domain‐specificity of prosopagnosia, and doing so would require testing an infinite number of categories in the visual world.…”

The sudden inability to recognize individual faces following brain damage was first reported in a scientific journal 150 years ago and termed ‘prosopagnosia’ 70 years ago. While the term originally identified a face‐selective neurological condition, it is now obscured by a sequence of imprecisions. First, prosopagnosia is routinely used to define symptoms of individual face recognition (IFR) difficulties in the context of visual object agnosia or other neurological conditions, or even in the normal population. Second, this over‐expansive definition has lent support to a long‐standing within‐category recognition account of prosopagnosia, that is, that the impairment of IFR reflects a general impairment in recognizing within‐category objects. However, stringent experimental studies of classical cases of prosopagnosia following brain damage show that their core impairment is not in recognizing physically similar exemplars within non‐face object categories. Instead, the impairment presents specifically for recognizing exemplars of the category of faces. Moreover, compared to typical observers, the impairment appears even more severe for recognizing individual faces against physically dissimilar than similar distractors. Here, I argue that we need to limit accordingly our definition of prosopagnosia to a clinical (i.e., neurological) condition in which there is no basic‐level object recognition impairment. Other criteria for prosopagnosia are proposed, with the hope that this conservative definition enables the study of human IFR processes in isolation, and supports progress in understanding the nature of these processes.

“…faces, cars, trees), though difficulty distinguishing between specific items in other categories (e.g. which face, which car, which tree) should not be grounds for exclusion, given ongoing debates about whether the prosopagnosic deficit is face-specific (Barton & Corrow, 2016). Detailed screening of memory can be done, but a statistically significant discrepancy between good short-term memory for words and poor familiarity for faces on the Warrington Recognition Memory test (Warrington, 1984) may serve a similar purpose (Corrow, et al, 2016; Liu, Corrow, Pancaroglu, Duchaine, & Barton, 2015).…”

The problem of being bad at faces

Developmental prosopagnosia has received increased attention in recent years, but as yet has no confirmed genetic or structural markers. It is not certain whether this condition reflects simply the low-end of the spectrum of normal face recognition, an ‘under-development’, or a pathologic failure to develop such mechanisms, a ‘mal-development’. This difference in views creates challenges for the diagnosis of developmental prosopagnosia by behavioural criteria alone, which also vary substantially between studies, with secondary effects on issues such as determining its prevalence. After review of the literature and the problems inherent to diagnoses based solely on behavioural data, we propose as a starting discussion point a set of two primary and four secondary criteria for the diagnosis of developmental prosopagnosia.

Selective defects of face familiarity associated to a left temporo-occipital lesion

et al. 2020

Acquired prosopagnosia is usually a consequence of bilateral or right hemisphere lesions and is often associated with topographical disorientation and dyschromatopsia. Left temporo-occipital lesions sometimes result in a face recognition disorder but in a context of visual object agnosia with spared familiarity feelings for faces, usually in left-handers. We describe a patient with a left temporo-occipital hemorrhagic lesion unexpectedly resulting in a deficit of face familiarity, which could represent a mild form of associative prosopagnosia. Our patient failed to feel familiarity feelings even with very well-known famous faces but had neither visual object agnosia nor defects with semantics or naming of celebrities. This was confirmed even when the patient was re-tested a year later. We speculate that a graded lateralization of face processing could be at the basis of occasional cases of prosopagnosia.
