Abstract/Summary

Previous studies have reported that temporarily ambiguous sentences sometimes cause reading disruption (garden-path effects). These studies have interpreted their finding as indicating that the human sentence processing device (the processor) initially assigns incorrect structures and subsequently attempts revision. That is a logical interpretation. However, no previous studies have demonstrated evidence of a causal relationship between garden-path effects and initial misanalysis. Besides, there is currently limited evidence regarding whether the processor conducts revision. The present study reports two self-paced reading experiments that investigated these fundamental issues about garden-path effects. Experiment 1 demonstrated that the processor initially misanalyses temporarily ambiguous sentences and consequently encounters garden-path effects and persists with initial misinterpretations. Experiment 2 similarly observed garden-path effects. Additionally, there was evidence that the processor constructs globally correct structures during revision. These findings provide evidence that garden-path effects result from initial misanalysis, and the processor conducts revision upon disambiguation.
