![]() ![]() Linguistic information can be conveyed in the form of speech and written text, but it is the content of the message that is ultimately essential for the higher-level processes in language comprehension, such as making inferences and associations between text information and knowledge about the world. The study demonstrates the modality fingerprints for language comprehension and indicates how low- and high working memory capacity readers deal with reading text presented in serial format. The activation of this network may be associated with phonological rehearsal of linguistic information when reading text presented in rapid serial visual format. Readers with higher working memory capacity showed more activation in a frontal-posterior network of areas (left angular and precentral gyri, and right inferior frontal gyrus). ![]() Readers with lower working memory capacity showed more activation of right-hemisphere areas (spillover of activation) and more activation in the prefrontal cortex, potentially associated with more demand placed on executive control processes. Results also showed individual differences in brain activation for reading comprehension. Listening comprehension was associated with extensive bilateral temporal cortex activation and more overall activation of the whole cortex. Reading comprehension was associated with more left-lateralized activation and with left inferior occipital cortex (including fusiform gyrus) activation. The results showed a common core of amodal left inferior frontal and middle temporal gyri activation, as well as modality specific brain activation associated with listening and reading comprehension. ![]() To mirror the transient nature of spoken sentences, visual input was presented in rapid serial visual presentation format. Participants had to decide if the sentences were true or false. An fMRI study measured brain activity while participants read and listened to sentences about general world knowledge. The study compared the brain activation patterns associated with the comprehension of written and spoken Portuguese sentences. ![]()
