Abstract
En 中文
This article presents the development and validation of a computerized clinical protocol for assessing Central Visual Processing (CVP). The protocol was designed to overcome limitations in current visual assessment tools by integrating sensory, perceptual, and cognitive visual functions within the dorsal and ventral processing streams. It comprises psychophysically controlled tasks measuring contrast sensitivity, texture perception, coherent motion, form integration, visual attention, reading-related eye movements, quantity estimation, and spatial-numerical mapping. Stimuli were developed using high-precision presentation software, and procedures were adapted to ensure both clinical feasibility and psychophysical validity. Method validation was conducted with 41 healthy adults through test-retest analysis, Cronbach's alpha, and Spearman-Brown split-half reliability. No significant differences were observed between first and second assessments (p > 0.05), and reliability indices showed strong internal consistency across subtests. These findings confirm the reproducibility and methodological robustness of the protocol. center dot A comprehensive computerized battery assessing central visual functions across dorsal and ventral streams center dot Psychophysical methods adapted for clinical precision and feasibility center dot Strong reliability demonstrated through test-retest, internal consistency, and split-half correlations
