Illusions of grammaticality have often been used to probe the properties of the human sentence processor in syntactic activities like subject--verb agreement, reflexive binding, and negative polarity item (NPI) licensing. Originally, NPI licensing in processing was thought to be a product of cue-based retrieval. Mounting evidence that the NPI…

Listeners make use of contextual cues during continuous speech processing that help overcome the limitations of the acoustic input. These semantic, grammatical, and pragmatic cues facilitate prediction of upcoming words and/or reduce the lexical search space by inhibiting activation of contextually inappropriate words that share phonological…

We studied the role of discourse coherence relations on structure formulation in sentence production by examining whether a connective, an essential signal of coherence relations, modulates the tendency for speakers to reuse sentence structures (i.e., structural priming). We further examined three possible modulating factors: the type of…

The present study examined transposed-word effects in a same-different matching task with sequences of 5 words. The word sequences were presented one after the other, each for 400 ms, the first in lowercase and the second in uppercase. The first sequence, the reference, was either a grammatically correct sentence or a scrambled ungrammatical…

One perennially important question for theories of sentence comprehension is whether the human sentence processing mechanism is "parallel" (i.e., it simultaneously represents multiple syntactic analyses of linguistic input) or "serial" (i.e., it constructs only a single analysis at a time). Despite its centrality, this question…

In four experiments, we investigated the impact of letter case (lower case vs. UPPER CASE) on the processing of sequences of written words. Experiment 1 used the rapid parallel visual presentation (RPVP) paradigm with postcued identification of one word in a five-word sequence. The sequence could be grammatically correct (e.g., "the boy likes…

In 2 ERP experiments participants read 4-word sequences presented for 200 ms (RPVP paradigm) and were required to decide whether the word sequences were grammatical or not. In Experiment 1, the word sequence consisted of either a grammatically correct sentence (e.g., "she can sing now") or an ungrammatical scrambled sequence (e.g.,…

Despite the empirical evidence for the power of the cognitive capacity of implicit learning of structures and regularities in several modalities and materials, it remains controversial whether implicit learning extends to the learning of temporal structures and regularities. We investigated whether (a) an artificial grammar can be learned equally…

Studies on agreement production consistently report an increase in production errors in the presence of an attractor mismatching the agreement feature of the target. In contrast, results from comprehension studies are mixed, ranging from lack of effect to facilitation. We report 2 forced-choice experiments and 2 self-paced reading experiments on…

We examined whether the position of modifiers in English influences how words are encoded and subsequently retrieved from memory. Compared with premodifiers, postmodifiers might confer more perceptual significance to the associated head nouns, are more consistent with the "given-before-new" information structure, and might also be easier…

One of the most compelling pieces of evidence for the presence of predictions in language comprehension comes from event-related potential (ERP) studies which show that encountering an adjective whose gender marking is inconsistent with that of a highly expectable noun leads to an effect at the adjective. Until now the mechanism underlying this…

Artificial grammar learning (AGL) has been probed with forced-choice behavioral tests (active tests). Recent attempts to probe the outcomes of learning (implicitly acquired knowledge) with eye-movement responses (passive tests) have shown null results. However, these latter studies have not tested for sensitivity effects, for example, increased…

Understanding language requires the ability to compose the meanings of words into phrase and sentence meanings. Formal theories in semantics have framed the hypothesis that all instances of meaning composition, irrespective of the syntactic and semantic properties of the expressions involved, boil down to a unique formal operation, that is, the…

Language is infinitely productive because syntax defines dependencies between grammatical categories of words and constituents, so there is interchangeability of these words and constituents within syntactic structures. Previous laboratory-based studies of language learning have shown that complex language structures like hierarchical center…

During spoken language comprehension, listeners make use of both knowledge-based and signal-based sources of information, but little is known about how cues from these distinct levels of representational hierarchy are weighted and integrated online. In an eye-tracking experiment using the visual world paradigm, we investigated the flexible…
