  • Title: Bisection of shapes and lines: analysis of the visual and motor aspects of pseudoneglect.
    Author: Macdonald-Nethercott EM, Kinnear PR, Venneri A.
    Journal: Percept Mot Skills; 2000 Aug; 91(1):217-26. PubMed ID: 11011891.
    Abstract:
    This study examined the visual and motor components of pseudoneglect as expressed on horizontal bisection tasks. Ten participants were tested on bisection of lines and elliptical shapes and judgement of pretransected lines. Results showed the same magnitude of leftward error on all three tasks, in contrast to previous findings for patients with visuospatial neglect who are known to bisect ellipses and circles much more accurately than lines. Participants' mean line bisection error was significantly further to the left than the mean subjective midpoint found on the judgement task. The findings contradict the claim that the visual component of pseudoneglect is caused by the same mechanism that causes visuospatial neglect but support the hypothesis that the motor component of pseudoneglect is similar to directional hypometria.
