Through the Eyes of Neglect Patients: A Preliminary Eye-Tracking Study of Unilateral Spatial Neglect

Increased scene complexity during free visual exploration reveals residual unilateral neglect in recovered stroke patients

“…Independently from the method of choice, the orientation bias towards the ipsilesional side was consistently identified as a correlate of unilateral neglect. The orientation shift could be measured and expressed by the relative time participants spent exploring their ipsi-versus their contralesional side ( Johnston and Diller, 1986 ), the number of fixations measured on the ipsi-versus the contralesional side ( Cazzoli, 2015 , LLorens and Noé, 2016 ; Machner et al, 2012 ) and by the mean and median fixation position on the horizontal axis ( Fruhmann Berger et al, 2008 ; Kaufmann et al, 2020 ).…”
