Wald chi-square was used to calculate p-values (function Anova in the package car; Fox and Weisberg, 2011).
in order to measure the influence of the context surrounding the complex NP, tokens were classified according to whether information inside the complex NP was enough to determine attachment (internally disambiguated; e.g., voice of men that was uttered) or whether it was also necessary to consult the context surrounding the complex NP (externally disambiguated).
