Magno App : Exploring Visual Processing in Adults with High and Low Reading Competence

Abstract

The aim of the study was to focus on whether visual processing differs between distinct levels of reading competence in young adults, from a regular orthography. We compared the 10% highest scoring (HRC) and the 10% lowest scoring groups (LRC) of reading competence (using the word chain test, WCT) in visual processing of global coherent motion and global coherent form among young adults in Norway. Results showed that the lowest scoring reading group had higher thresholds for detecting coherent motion, than the highest scoring reading group, indicating lower motion sensitivity in adults with low reading competence of a regular orthography. There was no significant difference between the groups in the coherent form control task. These results may indicate reduced sensitivity to temporally defined stimuli such as coherent motion in the group with low reading competence possible related to vulnerability of the visual dorsal stream.
