Representational pseudoneglect in line bisection

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