|dc.description.abstract||The present work suggests that sentence processing requires both heuristic and algorithmic processing streams,
where the heuristic processing strategy precedes the algorithmic phase. This conclusion is based on three self-paced
reading experiments in which the processing of two-sentence discourses was investigated, where context sentences
exhibited quantifier scope ambiguity. Experiment 1 demonstrates that such sentences are processed in a shallow
manner. Experiment 2 uses the same stimuli as Experiment 1 but adds questions to ensure deeper processing.
Results indicate that reading times are consistent with a lexical-pragmatic interpretation of number associated with
context sentences, but responses to questions are consistent with the algorithmic computation of quantifier scope.
Experiment 3 shows the same pattern of results as Experiment 2, despite using stimuli with different lexicalpragmatic
biases. These effects suggest that language processing can be superficial, and that deeper processing,
which is sensitive to structure, only occurs if required. Implications for recent studies of quantifier scope ambiguity are
