    INVESTIGATING INDIVIDUAL DIFFERENCES’ PREDICTION OF LANGUAGE PROFICIENCY OUTCOMES: A LATENT GROWTH CURVE MODELING APPROACH
    (2023) Rhoades, Elizabeth Rogler; Gor, Kira; Clark, Martyn; Second Language Acquisition and Application; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Although decades of research within the field of second language acquisition have been dedicated to investigating the impact of individual differences on second language learners’ success, longitudinal research focused on individual differences and their impact on adult second language acquisition is extremely limited. Additional longitudinal research on individual differences is necessary to further our understanding of the nature of the process of adult second language acquisition. This area of research is also critical to the U.S. Government and the Department of Defense as thousands of military service members work in language-related positions, and these service members’ maintenance of high levels of language proficiency is critical for our nation’s national security. The current study used a longitudinal design to investigate the impact of individual differences such as general cognitive ability, language aptitude, and attitude toward learning assigned second language (L2) on military service members’ language proficiency outcomes. Latent growth curve modeling (LGM) was used to model participants’ initial proficiency levels and growth trajectories, and measures of cognitive ability, language aptitude, and attitude toward learning assigned L2 were used to measure the impact of these individual differences on language proficiency outcomes. Additional variables including GPA, age, education level, number of language training hours, billet type, and sex were also included in the analyses. The results from the four phases of analyses support the conclusion that the predictive value of individual difference factors on language proficiency outcomes differ not only by DLI Language Difficulty Category, as suggested by previous research, but also by language and even language modality.

    MEMORY AND PREDICTION IN CROSS-LINGUISTIC SENTENCE COMPREHENSION
    (2014) Lago, Maria S.; Phillips, Colin; Linguistics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation explores the role of morphological and syntactic variation in sentence comprehension across languages. While most previous research has focused on how cross-linguistic differences affect the control structure of the language architecture (Lewis & Vasishth, 2005) here we adopt an explicit model of memory, content-addressable memory (Lewis & Vasishth, 2005; McElree, 2006) and examine how cross-linguistic variation affects the nature of the representations and processes that speakers deploy during comprehension. With this goal, we focus on two kinds of grammatical dependencies that involve an interaction between language and memory: subject-verb agreement and referential pronouns. In the first part of this dissertation, we use the self-paced reading method to examine how the processing of subject-verb agreement in Spanish, a language with a rich morphological system, differs from English. We show that differences in morphological richness across languages impact prediction processes while leaving retrieval processes fairly preserved. In the second part, we examine the processing of coreference in German, a language that, in contrast with English, encodes gender syntactically. We use eye-tracking to compare comprehension profiles during coreference and we find that only speakers of German show evidence of semantic reactivation of a pronoun's antecedent. This suggests that retrieval of semantic information is dependent on syntactic gender, and demonstrates that German and English speakers retrieve qualitatively different antecedent representations from memory. Taken together, these results suggest that cross-linguistic variation in comprehension is more affected by the content than the functional importance of gender and number features across languages.

    Subjacent Culture, Orthogonal Community: An Ethnographic Analysis of an On-Line Buffy the Vampire Slayer Fan Community
    (2013) Ali, Asim; Caughey, John L; American Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation presents an ethnographic analysis of the community of fans of the television series Buffy the Vampire Slayer whose members frequented the online linear posting board known as The Bronze. Buffy originally aired from 1997 until 2003, but the community that formed at the official Buffy fan site in 1997 continues on in real life and on line, having survived the end of Buffy and the closure of all three of its official posting boards. This study uses an interdisciplinary combination of textual analysis and ethnographic techniques (interviews, participant observation, autoethnography, cyberethnography) to ascertain the importance, relevance, and meaning of The Bronze community to its members, known as Bronzers. I argue that the nature of the linear posting board allowed Bronzers to form a unique and long-lived community by using The Bronze in creative and imaginative ways. In particular, language--to some degree appropriated from Buffy--was used by Bronzers to write a better world for themselves on line. Hence, the community is built on (and maintained by) language that is used in an unusually postmodern manner. As a group, Bronzers tend to be highly educated, literary, and artistic. To Bronzers, much of Buffy's appeal was its emotional realism and imaginative depth. Unusually for television, these elements were combined with strong female leading roles, a cast of bookish and somewhat countercultural characters, and a foregrounding of emotionality and interpersonal relationships. Bronzers were drawn to these aspects of Buffy--which formed its "gothic aesthetic"--and in turn created their own somewhat countercultural community, one that came to reflect their own close ties and emotional attachments. I argue that The Bronze community exists subjacent to mainstream cultural formations, and orthogonal to real life communities. Using this framework, a number of implications emerge for computer-mediated communication in general, including an explanation for the prevalence of hostility in online communication. Furthermore, when situated in its broader context, The Bronze can be seen as a meager palliative to the damaging effects of contemporary post-industrial capitalism, one that nonetheless illumines the brightly stultifying commonplaces that lead people to seek shelter in dimly-lit imagined spaces.

    The predictive nature of language comprehension
    (2009) Lau, Ellen Frances; Phillips, Colin; Linguistics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation explores the hypothesis that predictive processing--the access and construction of internal representations in advance of the external input that supports them--plays a central role in language comprehension. Linguistic input is frequently noisy, variable, and rapid, but it is also subject to numerous constraints. Predictive processing could be a particularly useful approach in language comprehension, as predictions based on the constraints imposed by the prior context could allow computation to be speeded and noisy input to be disambiguated. Decades of previous research have demonstrated that the broader sentence context has an effect on how new input is processed, but less progress has been made in determining the mechanisms underlying such contextual effects. This dissertation is aimed at advancing this second goal, by using both behavioral and neurophysiological methods to motivate predictive or top-down interpretations of contextual effects and to test particular hypotheses about the nature of the predictive mechanisms in question. The first part of the dissertation focuses on the lexical-semantic predictions made possible by word and sentence contexts. MEG and fMRI experiments, in conjunction with a meta-analysis of the previous neuroimaging literature, support the claim that an ERP effect classically observed in response to contextual manipulations--the N400 effect--reflects facilitation in processing due to lexical-semantic predictions, and that these predictions are realized at least in part through top-down changes in activity in left posterior middle temporal cortex, the cortical region thought to represent lexical-semantic information in long-term memory,. The second part of the dissertation focuses on syntactic predictions. ERP and reaction time data suggest that the syntactic requirements of the prior context impacts processing of the current input very early, and that predicting the syntactic position in which the requirements can be fulfilled may allow the processor to avoid a retrieval mechanism that is prone to similarity-based interference errors. In sum, the results described here are consistent with the hypothesis that a significant amount of language comprehension takes place in advance of the external input, and suggest future avenues of investigation towards understanding the mechanisms that make this possible.

    The Cognitive Functions of Language
    (Cambridge University Press, 2002-12) Carruthers, Peter
    This paper explores a variety of different versions of the thesis that natural language is involved in human thinking. It distinguishes amongst strong and weak forms of this thesis, dismissing some as implausibly strong and others as uninterestingly weak. Strong forms dismissed include the view that language is conceptually necessary for thought (endorsed by many philosophers) and the view that language is de facto the medium of all human conceptual thinking (endorsed by many philosophers and social scientists). Weak forms include the view that language is necessary for the acquisition of many human concepts, and the view that language can serve to scaffold human thought processes. The paper also discusses the thesis that language may be the medium of conscious propositional thinking, but argues that this cannot be its most fundamental cognitive role. The idea is then proposed that natural language is the medium for non-domain-specific thinking, serving to integrate the outputs of a variety of domain-specific conceptual faculties (or central-cognitive ‘quasi-modules’). Recent experimental evidence in support of this idea is reviewed, and the implications of the idea are discussed, especially for our conception of the architecture of human cognition. Finally, some further kinds of evidence which might serve to corroborate or refute the hypothesis are mentioned. The overall goal of the paper is to review a wide variety of accounts of the cognitive function of natural language, integrating a number of different kinds of evidence and theoretical consideration in order to propose and elaborate the most plausible candidate.
