A number of studies have found evidence for the so-called "ambiguity advantage," that is, faster processing of ambiguous sentences compared with unambiguous counterparts. While a number of proposals regarding the mechanism underlying this phenomenon have been made, the empirical evidence so far is far from unequivocal. It is compatible…

Research utilizing morphological priming has found that L2 speakers show facilitation from derived L2 primes, which could suggest morphological processing during derived L2 word recognition. However, the process of L2 derived word recognition is still poorly understood, with some arguing that the observed priming effects may not be morphological…

The age at which people acquire a word influences word recognition, known as the age of acquisition (AoA) effect. In the first language (L1), AoA effects are widely found in various languages and experimental tasks. Arbitrary Mapping Hypothesis proposes that AoA effects reflect the loss of network plasticity during the learning of mappings between…

Effects of concreteness and grammatical class on lexical-semantic processing are well-documented, but the role of sensory-perceptual and sensory-motor features of concepts in underlying mechanisms producing these effects is relatively unknown. We hypothesized that processing dissimilarities in accuracy and response time performance in nouns versus…

The Interface Hypothesis proposes that second language (L2) learners, even at highly proficient levels, often fail to integrate information at the external interfaces where grammar interacts with other cognitive systems. While much early L2 work has focused on the syntax-discourse interface or scalar implicatures at the semantics-pragmatics…

This paper investigates the difference between the production of grammatical determiners and lexical determiners in the production of adjective-noun phrases (NPs) in Danish. Models of sentence processing (Garrett in "Psychology of learning and motivation," Academic press, New York, pp 133-177, 1975; Bock in "J Mem Lang"…

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…

This study is aimed to re-examine the Interface Hypothesis via investigating the adult L2 acquisition of the word order variation of numeral classifier indefinites at the syntax-semantics and syntax-discourse interfaces in L2 Chinese. A computerized acceptability judgment task was administered to 41 advanced and intermediate adult Korean learners…

Emotion plays important roles in learning, memory, and other cognitive processes; it does so not only in the form of "macro-level emotion" (e.g., salient affective states and self-reportable motivational currents) but also in the form of "micro-level emotion" (e.g., subtle feelings and linguistic attributes that are usually…

Analysis of second language (L2) learners' language development can allow valid and reliable assessment of the learners' L2 linguistic knowledge, which can enable the teachers and researchers to choose appropriate teaching or experimental materials (Bardovi-Harlig & Bofman, 1989; Wolfe-Quintero et al., 1997). However, most language development…

Research on agrammatism has revealed that the nature of linguistic impairment is systematic and interpretable. Non-canonical sentences are more impaired than those of canonical sentences. Previous studies on Japanese (Hiroshi et al. 2004; Chujo 1983; Tamaoka et al. 2003; Nakayama 1995) report that aphasic patients take longer Response Time (RT)…

Individuals with agrammatic Broca's aphasia experience difficulty when processing reversible non-canonical sentences. Different accounts have been proposed to explain this phenomenon. The Trace Deletion account (Grodzinsky, 1995, 2000, 2006) attributes this deficit to an impairment in syntactic representations, whereas others (e.g., Caplan,…

Bilingual language control refers to how bilinguals are able to speak exclusively in one language without the unintended language intruding. Two prominent verbal theories of bilingual language control have been proposed by researchers: the inhibitory control model (ICM) and the lexical selection mechanism model (LSM). The ICM posits that…

The growing number of multilingual speakers poses an interesting question as to the way in which three or more languages are represented in the memory of a language user. The Revised Hierarchical Model (Kroll and Stewart in "J Mem Lang" 33: 149-174, 1994) or the Sense Model (Finkbeiner et al. in "J Mem Lang" 51(1), 1-22, 2004)…

In this dissertation, we present three empirical studies exploring the relationship between the central planning processes of spoken word production--lexical selection, phonological encoding, and phonetic encoding--and three other cognitive processes traditionally considered separate or peripheral to this core system. Study 1 examines the role of…
