Biasing thematic contexts for ambiguous sentences in a dichotic listening experiment.
In an experiment derived from Lackner and Garrett (1972) 80 subjects were given a dichotic listening task where they were presented with ambiguous sentences to an attended ear and disambiguating sentences to the other, unattended, ear. Each of the sentences was preceded by a thematic context that was biased for one meaning of the ambiguous sentence. In one-half of the instances the contexts biased a meaning consistent with that of the disambiguating sentence, and in the remaining one-half they biased the meaning of the ambiguous sentence in a way that was inconsistent with the meaning of the ambiguous sentence. The meanings of the ambiguous sentences the subjects perceived tended to be those that were consistent with the biasing context, even when that meaning was inconsistent with the meaning of the disambiguating sentence. Therefore, when ambiguous sentences are preceded by a thematic context, a single-reading explanation of the processing is more appropriate than a multiple-reading explanation.
