Construal: overview, motivation, and some new evidence

Is there underspecification in the syntactic phrase marker constructed during on-line sentence analysis? According to the construal hypothesis (Frazier & Clifton, 1996), a very limited amount and type of structural underspecification is available to the human sentence parsing mechanism. Here we present the basic definitions of construal, illustrating the theory with some already published evidence. We also discuss several new pieces of evidence, from our laboratory and elsewhere, that support the construal hypothesis. We end by raising the question of what kind of mechanism operates in the process of interpreting a nonprimary phrase (a phrase that receives an underspecified syntactic analysis), and conclude that it is not a process of competition between multiple activated possible analyses but instead is a process in which the sheer existence of ambiguity need not result in increased processing cost.
