    Potato not Pope: human brain potentials to gender expectation and agreement in Spanish spoken sentences
    (Elsevier, 2003-08-07) Wicha, Nicole; Bates, Elizabeth A.; Kutas, Marta; Moreno Bella, Eva
    Event-related potentials were used to examine the role of grammatical gender in auditory sentence comprehension. Native Spanish speakers listened to sentence pairs in which a drawing depicting a noun was either congruent or incongruent with sentence meaning, and agreed or disagreed in gender with the immediately preceding spoken article. Semantically incongruent drawings elicited an N400 regardless of gender agreement. A similar negativity to prior articles of gender opposite to that of the contextually expected noun suggests that listeners predict specific words during comprehension. Gender disagreements at the drawing also elicited an increased negativity with a later onset and distribution distinct from the canonical N400, indicating that comprehenders attend to gender agreement, even when one of the words is only implicitly represented by a drawing.

    Anticipating Words and Their Gender: An Event-related Brain Potential Study of Semantic Integration, Gender Expectancy, and Gender Agreement in Spanish Sentence Reading
    (MIT Press Direct, 2004-09) Wicha, Nicole; Kutas, Marta; Moreno Bella, Eva
    Recent studies indicate that the human brain attends to and uses grammatical gender cues during sentence comprehension. Here, we examine the nature and time course of the effect of gender on word-by-word sentence reading. Eventrelated brain potentials were recorded to an article and noun, while native Spanish speakers read medium- to high-constraint Spanish sentences for comprehension. The noun either fit the sentence meaning or not, and matched the preceding article in gender or not; in addition, the preceding article was either expected or unexpected based on prior sentence context. Semantically anomalous nouns elicited an N400. Genderdisagreeing nouns elicited a posterior late positivity (P600), replicating previous findings for words. Gender agreement and semantic congruity interacted in both the N400 windowā€”with a larger negativity frontally for double violationsā€”and the P600 windowā€”with a larger positivity for semantic anomalies, relative to the prestimulus baseline. Finally, unexpected articles elicited an enhanced positivity (500ā€“700 msec post onset) relative to expected articles. Overall, our data indicate that readers anticipate and attend to the gender of both articles and nouns, and use gender in real time to maintain agreement and to build sentence meaning.
