Duchaine BC , Weidenfeld A An evaluation of two commonly used tests of unfamiliar face recognition. R package , version 1. Retrieval of autobiographical memory in Alzheimer's disease: Finally, the number of transitions was computed for each facial feature, separately. Evidence from individual differences and amnesia. Federica Biotti does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment. This experimental manipulation reduces the ability to use novelty detection, and likely required hippocampal memory representations to support detailed knowledge of spatial relations among facial features.
Faces are special but not too special: spared face recognition in amnesia is based on familiarity.
Prosopagnosia is thought to be the result of abnormalities, damage, or impairment in the right fusiform gyrus, a fold in the brain that appears to coordinate the neural systems that control facial perception and memory. Often prosopagnosics grow up blaming themselves, attributing their face recognition difficulties to a lack of focus or poor memory. This test can only be taken once.

If you don't practice, you soon forget the needed skills -- they don't stick. It'd be great if the research team released an app for this training.

A selective impairment in learning new faces. Recognition confidence judgments were used to plot receiver operating characteristics ROCs in order to more fully quantify recognition performance and to estimate the contributions of recollection and familiarity. MZ's facial recognition abilities decreased when she stopped practicing, and my stereovision declined when I stopped my vision therapy procedures for six months. Networks of domain-specific and general regions involved in episodic memory for spatial location and object identity. Autobiographical episodic and semantic memory in semantic dementia and amnesia: If you have a deficit in a certain skill, you need to concentrate on that particular skill to get better. Visual processing deficits as assessed by spatial-frequency contrast sensitivity and backward-masking in normal aging and Alzheimer's disease.
Tippett's group described its cause as a "disconnection between learning mechanisms and domain-specific representations". Abnormal fMRI adaptation to unfamiliar faces in a case of developmental prosopamnesia. A year follow-up to a sabbatical in Jerusalem. Retrieval of autobiographical memory in Alzheimer's disease: That is, recognition accuracy was higher for faces studied in the fixed condition and subsequently tested in the same view than when tested in a novel viewpoint corrected recognition for same viewpoint:
