Good-enough representations in language comprehension. Current Directions in Psychological Science, 11, 11-15.
How do we generate the meaning of a sentence beyond just
knowing what each individual word means? One source of information to help us
understand a sentence comes from our knowledge of syntax, or the linguistic
rules we know for how words go together. Another source of information comes
from our ability to problem-solve, learn or discover information based on our
past experience and present context, also known as a heuristic process. Although
not as detailed and specific as linguistic rules, heuristics can be applied
very rapidly. The application of heuristics can allow for the quick creation of
a ‘good enough’ representation of a sentence, which could result in
misinterpretations in some cases.
The authors reviewed two sources of evidence to support
their idea that initial processing of sentences is ‘good enough’. In one study,
participants were shown ‘garden-path sentences’, that is, sentences in which
the most likely grammatical interpretation suggested by the first words of the
sentence turns out to be wrong. The assumption has been that when readers
become aware of the difficulty understanding, they re-interpret the sentence
coming to a full and complete representation of the sentence. The results of
the reported study, however, indicated that even though participants were able
to indicate their understanding of the key confusion after reviewing the
garden-path sentence, they persisted in misunderstanding another aspect of the
sentence. The authors suggested that the processing of the sentences was ‘good
enough’ to allow comprehension of the main idea required for the context but
did not reflect the true content of the sentence. In another study,
participants were asked to judge the possible truth of active sentences like
‘The man bit the dog’ and passive sentences like ‘The dog was bitten by the
man’. More errors were made on the
passive sentences especially when the word order was unexpected. The authors
argued that the linguistic representation of passive sentences was fragile, and
was often outweighed by the heuristics favouring the error response.
The authors suggested that ‘good enough’ language processing
is often successful because the context of the sentence or the conversation
supports the linguistic interpretation generated. In cases where the context or
heuristics are unclear or unknown, however, individuals with weak linguistic
representations such as children with language impairment may fail to
comprehend the sentence.
