[en] Large Scale Screener ; Visual Perceptual Processing ; Functional Vision Impairment
[en] Cerebral Visual Impairment (CVI) is a term used to designate a neurological disorder of the visual pathways impacting visual processes at any given level (Lueck et al., 2019). Due to the advances in perinatal and medicinal care, CVI’s occurrence has increased significantly over the last years (Chokron & Dutton, 2016). The condition almost always entails aggregated functional vision impairments, i.e., limitations on the use of binocular vision during everyday tasks (Dutton, 2015). CVI can have effects on school achievements if undetected. Early detection is thus key to offer appropriate aids to avoid a negative impact on learning processes. The aim of this project is to develop a large-scale screener at the beginning of formal schooling, to identify functional vision impairments early on. For this reason, a set of items assessing different visual functions will be incorporated into the Luxembourgish school monitoring program. Based on a theoretical model of visual perceptual processing (Humphreys and Riddoch, 1987), we developed timed and non-timed items that can be administered in a large-scale classroom setting which target different stages of visual perceptual processing. Furthermore, we included visual functions connected with both dorsal and ventral streams, visual spatial processing, visual exploration and visual memory. We will present the design of the large-scale screener in relation to the theoretical model, as well as the rationale used to include or exclude various perceptual visual functions in the final test. Furthermore, we will explain the planned data collection and tool validation processes.
