Theories underlying theWLP are described, as are its empirical findings. Recent research from other labsthat has extended the findings of the original WLP is briefly described. Theauthors' research that draws on the findings of WLP are noted as well. An under-lying theme in this work is that relationships (and interactions) with parentsand friends can serve as protective or exacerbating factors in the developmentalcourse of social withdrawal and its concomitants (including social anxiety). 收起
