Abstract(in English) | It is observed that in English the composition of a semelfactive predicate, jump, and a for-adverbial, such as 1_"Frances jumped for an hour," engenders an iterative reading (Frances jumped repeatedly for an hour). Previous studies report that this iteration generation engenders processing cost (vs. 2_"Frances ran for an hour"). The cost is captured by the Partition Measure (PM) hypothesis, which argues that for-adverbials contain a universal quantifier that quantifies over the subintervals of the interval that they denote (e.g., hour). A non-infinitesimal partition measure interpretation of the subintervals yields an iterative reading, construed out of the local lexical meaning of the verbal denotation (e.g. jump). An infinitesimal partition measure yielding a continuous reading (one jumping event), implausible in (1), is nonetheless always available and cost-less. Crucially, this account predicts that an iterative reading emerging from the composition of a for-adverbial with a "durative" predicate, as in 3_"Frances ran for 10 years", also engenders cost from the necessary PM construal, this time from the entire sentential context. For-adverbial composition thus demands a partition measure obtained from structured individuals--entities with structured subparts. The relation between the sub-parts, i.e., non-infinitesimal vs. infinitesimal, yields the iterative vs. continuous readings observed. A Self-Paced Reading_Study.1 and an fMRI_Study.2 from our lab show that, as predicted, both iterative conditions--punctual_1 & durative_3--are costly vis-a-vis no-iteration_2. fMRI results also show brain activation consistent with the source of partition measure: lexical vs. sentential, and convergent deactivation, consistent with the partition-measure search. The observed PM retrieval process evidences a model of real-time sentential semantic composition that demands (a) rich lexical meanings whose full realization depends on key contextual information; (b) a search process that uses lexical vs. sentential locality as a processing complexity metric, and (c) a conceptual structure system that ultimately resolves the underspecified lexical variables. |
