  1. Ivans Chou & Lucia M. Vaina (1995). Two-Dimensional Symmetric Form Discrimination: Fast Learning, but Notthat Fast. Synthese 104 (1):33 - 41.
    Several authors have characterized a striking phenomenon of perceptual learning in visual discrimination tasks. This learning process is selective for the stimulus characteristics and location in the visual field. Since the human visual system exploits symmetry for object recognition we were interested in exploring how it learns to use preattentive symmetry cues for discriminating simple, meaningless, forms. In this study, similar to previous studies of perceptual learning, we asked whether the effects of practice acquired in the discrimination of pairs of (...)

  3. Lucia M. Vaina, Harold Goodglass & Lawren Daltroy (1995). Inference of Object Use From Pantomimed Actions by Aphasics and Patients with Right Hemisphere Lesions. Synthese 104 (1):43 - 57.
    Twenty-four aphasic and fifteen right brain-damaged subjects were compared on their ability to identify the objects whose use was depicted in a series of twenty videotaped pantomimes. Aphasics were inferior to right brain-damaged patients in inferring object use. Success was correlated with Performance IQ, but not with language measures. Analysis of movement features contributing to subjects' choices reveal speed of movement and object weight to be the most robust and hand shape and size to be the most fragile.

  4. Lucia M. Vaina (1990). Common Functional Pathways for Texture and Form Vision: A Single Case Study. Synthese 83 (1):93 - 131.
    A single case study of a patient, D.M., with a lesion in the region of the right occipito-temporal gyrus is presented. D.M. had well-preserved language and general cognitive abilities. Colour discrimination, contrast sensitivity, gross depth perception, spatial localization, and motion appreciation were within normal limits.On the evaluation of perceptual abilities, he failed to identify two-dimensional shapes from stereoscopic vision, motion, and texture although in all cases he (...)
