A critical review and meta-analysis of the perceptual pseudoneglect across psychiatric disorders: is there a continuum?
The phenomenon known as "perceptual pseudoneglect" refers to the leftward bias in visuospatial attention in non-clinical samples, possibly as a consequence of right hemisphere dominance for visuospatial attention. The degree of such a lateralized visuospatial attention bias is often assessed using the line bisection task. Interestingly, various psychiatric disorders may influence the expression of this phenomenon. The aim of this paper was to perform a critical appraisal of the literature on the expression of the perceptual pseudoneglect across all psychiatric disorders accompanied by meta-analytical evaluation of the data. Moreover, we will discuss whether this phenomenon may be considered as a trait marker across different psychiatric disorders.
