Face-Space Architectures: Evidence For The Use Of Independent Color-Based Features, Adrian Nestor, David Plaut, Marlene Behrmann
Face-Space Architectures: Evidence For The Use Of Independent Color-Based Features, Adrian Nestor, David Plaut, Marlene Behrmann
Marlene Behrmann
The concept of psychological face space lies at the core of many theories of face recognition and representation. To date, much of the understanding of face space has been based on principal component analysis (PCA); the structure of the psychological space is thought to reflect some important aspects of a physical face space characterized by PCA applications to face images. In the present experiments, we investigated alternative accounts of face space and found that independent component analysis provided the best fit to human judgments of face similarity and identification. Thus, our results challenge an influential approach to the study of …
Facing Changes And Changing Faces In Adolescence: A New Model For Investigating Adolescent-Specific Interactions Between Pubertal, Brain And Behavioral Development, K. Suzanne Scherf, Marlene Behrmann, Ronald Dahl
Facing Changes And Changing Faces In Adolescence: A New Model For Investigating Adolescent-Specific Interactions Between Pubertal, Brain And Behavioral Development, K. Suzanne Scherf, Marlene Behrmann, Ronald Dahl

Adolescence is a time of dramatic physical, cognitive, emotional, and social changes as well as a time for the development of many social–emotional problems. These characteristics raise compelling questions about accompanying neural changes that are unique to this period of development. Here, we propose that studying adolescent-specific changes in face processing and its underlying neural circuitry provides an ideal model for addressing these questions. We also use this model to formulate new hypotheses. Specifically, pubertal hormones are likely to increase motivation to master new peer-oriented developmental tasks, which will in turn, instigate the emergence of new social/affective components of face …
Bilateral Hemispheric Processing Of Words And Faces: Evidence From Word Impairments In Prosopagnosia And Face Impairments In Pure Alexia, Marlene Behrmann, David Plaut
Bilateral Hemispheric Processing Of Words And Faces: Evidence From Word Impairments In Prosopagnosia And Face Impairments In Pure Alexia, Marlene Behrmann, David Plaut
Marlene Behrmann
Considerable research has supported the view that faces and words are subserved by independent neural mechanisms located in the ventral visual cortex in opposite hemispheres. On this view, right hemisphere ventral lesions that impair face recognition (prosopagnosia) should leave word recognition unaffected, and left hemisphere ventral lesions that impair word recognition (pure alexia) should leave face recognition unaffected. The current study shows that neither of these predictions was upheld. A series of experiments characterizing speed and accuracy of word and face recognition were conducted in 7 patients (4 pure alexic, 3 prosopagnosic) and matched controls. Prosopagnosic patients revealed mild but …
The Neural Basis Of Visual Word Form Processing: A Multivariate Investigation, Adrian Nestor, Marlene Behrmann, David Plaut
The Neural Basis Of Visual Word Form Processing: A Multivariate Investigation, Adrian Nestor, Marlene Behrmann, David Plaut

Current research on the neurobiological bases of reading points to the privileged role of a ventral cortical network in visual word processing. However, the properties of this network and, in particular, its selectivity for orthographic stimuli such as words and pseudowords remain topics of significant debate. Here, we approached this issue from a novel perspective by applying pattern-based analyses to functional magnetic resonance imaging data. Specifically, we examined whether, where and how, orthographic stimuli elicit distinct patterns of activation in the human cortex. First, at the category level, multivariate mapping found extensive sensitivity throughout the ventral cortex for words relative …
