Context Effects in Sentence Reading
نویسندگان
چکیده
The current work investigates the effect of context on the neural representation of concepts, measured by MEG during reading of sentences in active and passive voice. Two approaches to incorporating context are proposed − one by including estimates of the functional connectivity of the MEG sensors, and the other by creating a joint representation of the sentences using an HMM. The suggested methods are evaluated against non-context models in two tasks − classifying sentences as active or passive and identifying pairs of active and passive sentences that exemplify the same concept. Both supervised and unsupervised learning frameworks are presented, as well as the effect of the number of hidden states in the unsupervised framework on the task accuracies.

Two studies investigated the effects of prosody, context and thematic fit on off-line and on-line processing of sentences like John greeted Paul yesterday and Ben today. Such sentences are ambiguous between the so-called 'nongapping' reading, where John greeted Ben, and the highly unpreferred 'gapping' reading, where Ben greeted Paul. Participants listen to dialogues and give a speeded response...

متن کاملEffects of syntactic context on eye movements during reading
Previous research has demonstrated that properties of a currently fixated word and of adjacent words influence eye movement control in reading. In contrast to such local effects, little is known about the global effects on eye movement control, for example global adjustments caused by processing difficulty of previous sentences. In the present study, participants read text passages in which voi...
