Representational pseudoneglect in line bisection

Abstract

Representational pseudoneglect refers to a bias towards the left side of space that occurs when visual information is remembered. Recently there have been a number of demonstrations of such representational pseudoneglect. In the current paper we report an experiment where we adopted the classic line bisection paradigm to study representational pseudoneglect. Participants bisected horizontal lines that were shown in extra-personal space. When lines were visible on the screen, there was no evidence of any leftward bias. However, when lines were bisected from memory, participants demonstrated a clear bias to the left. This is the first demonstration of a leftward bias in bisection of remembered visually presented lines.
