Congenital prosopagnosia (cPA) is a selective impairment in the visual learning and recognition of faces without detectable brain damage or malformation. There is evidence that it can be inherited in an autosomal dominant mode of inheritance. We assessed the capacity for visual mental imagery in 53 people with cPA using an adapted Marks' VVIQ (Vividness of Visual Imaging Questionnaire). The mean score of the prosopagnosic group showed the lowest mental imagery scores ever published for a non… Expand
Congenital prosopagnosia. Diagnosis and mental imagery: Commentary on “Tree JJ, and Wilkie J. Face and object imagery in congenital prosopagnosia: A case series.”
TLDR
The leading symptom in cPA is an irritating inability to decide whether a face is familiar or not, which discerns the condition from acquired prosopagnosia, where most of the affected people report that all faces look definitely unfamiliar to them. Expand
Configural and featural processing in humans with congenital prosopagnosia.
TLDR
It is indicated that congenital prosopagnosia is a face-specific deficit, but that this shortcoming is particularly pronounced for processing configural facial information. Expand
Prosopagnosia and disorders of face processing.
TLDR
Recon rehabilitative studies have shown some modest ability to improve face perception in prosopagnosic subjects through perceptual training protocols. Expand
Congenital prosopagnosia: multistage anatomical and functional deficits in face processing circuitry
TLDR
A comprehensive behavioral pattern is found, an impairment in visual recognition for faces and buildings that spared long-term memory for faces with negative valence and suggests that anatomic curtailing of visual processing in the lingual gyrus plays a substantial role. Expand
Face and object imagery in congenital prosopagnosia: A case series
TLDR
Overall, it is advocated that the findings demonstrate a category specific visual imagery impairment in congenital prosopagnosia, such that general imagery skill can be intact in such cases. Expand
Mental imagery in congenital prosopagnosia: A reply to Grüter et al.
  • J. Tree
  • Medicine, Psychology
  • Cortex
  • 2011
TLDR
Criticism of Tree and Wilkie (2010) is levelled, suggesting that the findings of both studies don’t necessarily conflict, and that vividness testing and accuracy testing using forced choice measures can be agreed on. Expand
Congenital prosopagnosia without object agnosia? A literature review
TLDR
This paper reviews all CP cases from 1976 to 2016, and explores the evidence for the association or dissociation of face and object recognition, and considers the implications for theories of functional organization of the visual system. Expand
Electrophysiological studies of face processing in developmental prosopagnosia: Neuropsychological and neurodevelopmental perspectives
TLDR
Findings from recent event-related brain potential (ERP) studies of face perception and face recognition in developmental prosopagnosia suggest that visual face memory and semantic memory can become disconnected in some individuals with DP. Expand
Congenital prosopagnosia: A case report
TLDR
A forty-six year-old woman with congenital prosopagnosia is presented, and it appears that the agnosia in this case best fits the group of categories termed “associative”. Expand
Aphantasia: The science of visual imagery extremes.
TLDR
Preliminary evidence suggests that lifelong aphantasia is associated with prosopagnosia and reduction in autobiographical memory; hyperphantasia are associated with synesthesia; and aphantasic individuals can be highly imaginative and complete many tasks that were previously thought to rely on visual imagery, demonstrating that visualization is only one of many ways of representing things in their absence.

Structural imaging reveals anatomical alterations in inferotemporal cortex in congenital prosopagnosia.
TLDR
Detailed morphometric and volumetric analyses of the occipitotemporal cortex in a group of CP individuals and matched control subjects implicate a specific cortical structure as the neural basis of CP and target the aF gyrus as a potential site for further, focused genetic investigation. Expand

Faces as Objects of Non-Expertise: Processing of Thatcherised Faces in Congenital Prosopagnosia
TLDR
A speeded grotesqueness decision task with thatcherised faces shows dissociate patterns between people with and without cPA, which is interpreted as a diagnostic sign of impaired configural processing, being the primary cause of the absence of ‘face expertise’ in prosopagnosia. Expand

TLDR
Analysis of single cases showed that patients with lesions of the left temporo-occipital region failed to benefit from the imagery instruction in the memorizing of concrete words, but these patients could nonetheless solve correctly the visuospatial imagery tasks. Expand
Less impairment in face imagery than face perception in early prosopagnosia
TLDR
The confirmation of the reports of less impaired face imagery in some prosopagnosics cannot be attributed to pre-lesion storage, and it is speculated that face recognition, in contrast to object recognition, relies more heavily on a representation that describes the initial spatial filter values so the metrics of the facial surface can be specified.

Disorders of visual recognition.
TLDR
Diagnostic and clinical features characterizing the disruption of the last stage of visual information processing are focused on, the failure to identify what a stimulus represents despite evidence that its three-dimensional structure has been properly reconstructed. Expand

Seven family pedigrees with 38 cases in two to four generations of suspected hereditary prosopagnosia, detected using a screening questionnaire provide compelling evidence for significant genetic contribution to face recognition skills and contribute to the promise offered by the emerging field of cognitive neurogenetics.
