Introduction: an overview of the acquisition of reference

Language is a social tool that allows us to speak to others about the world. In doing so we need words that pick out those entities that we want to talk about. Linguistic expressions that identify such entities are known as referential or referring expressions, including proper names (Laura), natural kind terms (water, gold, tiger), indexicals (you, I, she), and definite descriptions (the dog, the smallest positive number). The mechanisms of reference have been the subject of intense speculation, and the debate over descriptive (Frege 1892/1948; Searle, 1958) vs. causal (Kripke, 1972/1980) or hybrid theories of reference (Evans, 1973) is still rife in the semantics literature (Genone & Lombrozo, 2012; Lam, 2010; Martí, 2014). Whatever the theoretical approach to reference, from a developmental perspective the three key questions are the following: What is the trajectory of language learners’ comprehension and production of referential expressions? To what extent, and in which contexts, do children abide by the same linguistic constraints as adults in their referential choices? How do cross-linguistic differences shape the process of referential choice acquisition

COMMITMENT AND FLEXIBILITY IN THE DEVELOPING PARSER

This dissertation investigates adults and children's sentence processing mechanisms, with a special focus on how multiple levels of linguistic representation are incrementally computed in real time, and how this process affects the parser's ability to later revise its early commitments. Using cross-methodological and cross-linguistic investigations of long-distance dependency processing, this dissertation demonstrates how paying explicit attention to the procedures by which linguistic representations are computed is vital to understanding both adults' real time linguistic computation and children's reanalysis mechanisms. The first part of the dissertation uses time course evidence from self-paced reading and eye tracking studies (reading and visual world) to show that long-distance dependency processing can be decomposed into a sequence of syntactic and interpretive processes. First, the reading experiments provide evidence that suggests that filler-gap dependencies are constructed before verb information is accessed. Second, visual world experiments show that, in the absence of information that would allow hearers to predict verb content in advance, interpretive processes in filler-gap dependency computation take around 600ms. These results argue for a predictive model of sentence interpretation in which syntactic representations are computed in advance of interpretive processes. The second part of the dissertation capitalizes on this procedural account of filler-gap dependency processing, and reports cross-linguistic studies on children's long-distance dependency processing. Interpretation data from English and Japanese demonstrate that children actively associate a fronted wh-phrase with the first VP in the sentence, and successfully retract such active syntactic commitments when the lack of felicitous interpretation is signaled by verb information, but not when it is signaled by syntactic information. A comparison of the process of anaphor reconstruction in adults and children further suggests that verb-based thematic information is an effective revision cue for children. Finally, distributional analyses of wh-dependencies in child-directed speech are conducted to investigate how parsing constraints impact language acquisition. It is shown that the actual properties of the child parser can skew the input distribution, such that the effective distribution differs drastically from the input distribution seen from a researcher's perspective. This suggests that properties of developing perceptual mechanisms deserve more attention in language acquisition research

Formal Linguistic Approaches to Adult Second Language (L2) Acquisition and Processing

The relative conformity with which (typically developing) children attain adult grammatical competence—ultimate attainment—and the similarity in developmental paths along which they progress is remarkable (e.g., Ambridge & Lieven, 2011; Clark, 2003; Guasti, 2002; Synder, 2007). This achievement is, however, so ubiquitous and mundane that we seldom marvel at it. Of course, monolingual adult grammars may also differ from one another, especially for some domains of grammar (e.g., Dąbrowska, 1997, 2012), but such variability pales in comparison to the variation in adult non-native second language (L2) grammars. Indeed, the path and outcomes of L2 acquisition can be highly variable from one individual to another, even under seemingly comparable contexts. Individual and group-level factors in adulthood that either do not apply or apply with much less consequence in young childhood conspire to explain at least some of the gamut of L2 variability

Formal linguistics approaches to adult second language acquisition and processing

This chapter provides an overview of the major contemporary trends driving adult, non-native language acquisition and processing research from a formal linguistic theory perspective. In doing so, we contextualize for the reader what formal linguistics is, inclusive of the main tenets of generative grammar. We provide an overview of the formative questions of generative second language acquisition (GenSLA), focusing on how they have been recast/refocused over time in accord with: (a) the evolution of formal linguistic theory, (b) insights from GenSLA’s own research over three decades and other paradigms of SLA, as well as (c) the expansion of empirical testing methods to include psycholinguistic and neurolinguistic processing measures. All of the aforementioned is done with the backdrop of adult language learning in mind; that is, what do formal linguistic studies on adult non-native language acquisition and processing contribute to our understanding of how L2ers typically learn/process language

Pronoun processing in post-stroke aphasia:A meta-analytic review of individual data

Pronouns constitute a heterogeneous class of linguistic elements, allowing for expression of referential relationships. Pronouns have an important place in daily communication which speakers and listeners rely heavily on for. Aphasia literature has evidenced that pronoun processing is impaired in people with aphasia (PWA), although explanations underpinning pronoun impairments are mixed. To address this, through a systematic literature review, we identified 42 studies which examined pronoun processing (both production and comprehension) in 474 PWA across 16 different languages. An initial meta-analysis was conducted on the overall data with all PWA and pronoun conditions with an outcome measure indicating whether or not pronoun processing is individually impaired in PWA. Further meta-analytic models were built to compare certain conditions of particular interest (e.g. reflexives vs object pronouns, object vs subject wh-pronouns) in an attempt to further disentangle the explanations behind their difficulty in use. Outputs from our meta-analysis suggest that: (i) a form of pronoun impairment is consistently present in aphasia regardless of aphasia type, fluency or language spoken; (ii) pronoun variables show selectivity in their impairment, for instance, reflexives are better preserved over object pronouns, and the subject-advantage in who-pronouns is language-selective; and (iii) other important linguistic variables that largely predict pronoun impairments include aspects like argument position of subject/object phrases, case marking, cliticization, and the presence of relative clause constructions. These outputs are discussed in relation to neurolinguistic hypotheses that predict pronoun impairments in aphasia
