Full Issue

Abstract

The second issue of Volume 6 of the International Journal of Neurology (1967) was dedicated to perception. It began with editorials in Spanish and English and brought together major contributions on the mechanisms and organization of perceptual processes from biological, psychological, and cognitive perspectives.

The articles addressed cognitive style and individual differences in perception (Witkin and Oltman), the hierarchical organization of perceptual systems (Forgus), and the biological foundations of visual perception and imagery in humans (Boernstein). Other studies proposed integrative models, such as a steady-state theory linking evolution, learning, perception, hallucination, and dreaming (Fischer and Rockey), and examined intensity functions in sensory systems (Stevens).

The issue also included a detailed analysis of color blindness, using anomaloscope testing to explore physiological mechanisms of vision (Pickford), a tribute to André Thomas, and sections devoted to book reviews and news.

Overall, this volume reflected a multidisciplinary exploration of perception, emphasizing its neurobiological, psychological, and phenomenological dimensions within modern neuroscience.
