title: The interaction between language and visual spatial attention systems in grammatical gender processing. An N2pc study.
abstract: This ERP study employed an N2pc paradigm to investigate possible functional interactions between mechanisms of visual spatial attention and grammatical gender processing. Previous studies showed that the N2pc, an attention-related ERP component, can be modulated by lexical-semantic variables. However, it remains to be seen whether the N2pc can be affected by grammatical features as well. To test this, we conducted an N2pc study with Italian word pairs whose grammatical gender either agreed or disagreed. Participants read a centrally presented noun followed by an adjective in a lateralized position during a gender agreement task. Between 170 and 310ms, the N2pc was elicited contralaterally to the adjective position with a left-lateralized effect of the agreement manipulation. These results suggest that this component could be influenced by grammatical features, supporting a functional interaction between processes mediating visual spatial attention and agreement computation.
