Domain-specific executive control and the revision of misinterpretations in sentence comprehension

Abstract

Two individual differences experiments examined the relationship between executive control and the revision of misinterpretations in sentence comprehension. Garden-path sentences were used as they often lead to initial misinterpretations, necessitating revision during comprehension. In addition to garden-path revision, verbal and non-verbal executive controls were assessed by using the verbal and non-verbal version of the Stroop task. Experiment 1 showed that garden-path revision errors in a grammaticality judgement task correlated with verbal Stroop interference errors. Experiment 2 further showed that the time taken to revise the garden-path interpretation correlated with the time taken to resolve verbal Stroop interference, but not with the time taken to resolve non-verbal Stroop interference. Together, the results argue for a role of executive control, which is possibly domain-specific, in the revision of misinterpretations during sentence comprehension.
