The role of working memory and punctuation in the processing of Garden Path sentences: An Online Study

Ambiguity resolution has been a topic of debate in language processing models. The present study investigated the impact of punctuation and working memory in Garden Path structures and related these concepts with assumptions made under the Good Enough parsing approach. A word-by-word self-paced reading task was used to assess the effects. A backwards digit span and a reading span task were administered to measure the participant’s working memory capacity. The study found evidence for the presence of Garden Path effects in Late Closure structures. In the form of response accuracy to the comprehension questions, the data supports the Good Enough parsing approach’s assumption that ambiguities are not fully resolved. The scores on the backwards digit span task correlated positively with response accuracy on comprehension questions while reading span scores did not. Punctuation did not impact reading time of the disambiguating region nor response accuracy.
