Abstract

Laser line bisection (LLB) is a newer visuospatial task that, unlike pen-and-paper line bisection, can be performed in extrapersonal space. We examined the utility of LLB by manipulating factors known to influence visuospatial biases: elevation, lateral position, and distance. In contrast to the leftward biases typical of peripersonal line bisection, we observed an overall rightward bias, with stronger rightward bisections at low elevations, farther distances, and rightward lateral positions. The findings are consistent with those observed in pseudoneglect studies, and mirror those seen in neglect patients, suggesting that LLB is a useful task for studying visuospatial biases in extrapersonal space.
