Adams-Webber, J. (1985) Self-other contrast and the development of
personal constructs. _Canadian Journal of Behavioral Science Vol.17_,
303-314.
Frans Epting also wrote an article regarding children's personal
constructs in the first issue of IJPCP (I think), maybe somebody can
confirm this for me.
Hope that this was helpful,
