In this thesis, I conduct a preliminary analysis of the Islamic State of Iraq and Al-Sham's travel manual-cum-propaganda ebook Hijrah to the Islamic State, which has been used by people from various parts of the world attempting to enter Syria and join the terrorist organization. Using techniques from discourse and propaganda analysis I examine how the author of the text uses discursive resources to construct the reader of the text, the author's expectations for the reader, and the act of traveling to Syria. I then use news articles from varying organizations as well as the Islamic State-produced periodical magazine Dabiq to locate the document within the context of Islamic State affairs and propaganda. Subsequently, I show that the use of discursive resources is consistent with the ethos espoused in Dabiq, and in addition to serving as a guide to entering Syria Hijrah to the Islamic State is also a soft introduction into the radical belief systems of the terrorist group itself.

This thesis covers second language acquisition in regards to age, examining the difference between elementary and high school students. The primary language of all the students tested was English. The second language being tested in this study is German. The general age range in the elementary students observed was 7-12 years old. The high school students' ages were between 14-18 years old. The environment consisted of a physical education atmosphere, which includes: gyms, outside recreational areas, fitness equipment, fields, etc. Methods used to conduct this study were visual and auditory/verbal approaches. No direct instruction was provided to the students, they were assessed based on their ability to absorb the information when provided to them indirectly in a traditional classroom atmosphere. In addition, direct instruction is also not conducive to a physical education setting as it has the potential to detract from the necessary lesson content.

This dissertation study examined the language ideologies about the different languages used in Sri Lanka to understand how they may reflect and align with ideologies about ethnicity and national belonging and structures of power operating in Sri Lankan society. It was a qualitative study which gathered data by interviewing twelve participants from the four main ethnic communities of Sri Lanka. Through the analysis of data comprising observations about language evaluations and practices, three main themes were generated. First, the study showed that Sri Lanka is a complex multilingual context in which the status of different languages changes according to context, audience as well as the participants of an interaction and that therefore it is difficult to describe languages by static labels such as “first”, “second” or “link” language. Secondly, the study found the situation of English in Sri Lanka is still largely influenced by cultural practices introduced during colonial rule which has caused it to function as a basis for social division. The study also found that the situation of Sinhala and Tamil in Sri Lanka is shaped by ideologies about ethnicity and the social power that the two ethnic groups, the Sinhalese and Tamils, who speak the two languages, hold in society. Taken together these three main findings of the study showed that language ideologies in circulation in Sri Lanka as observed by the study participants were closely linked to and align with and sometimes even reinforce ideologies about ethnicity, national belonging and power in Sri Lankan society.

Diffusion weighted imaging utilizes magnetic resonance imaging to capture white matter tracts in the brain. Many studies have utilized this technique to measure white matter structures looking for evidence of anatomical and physiological differences in Autism Spectrum Disorder (ASD). Parkinsonian-like symptoms have been documented and self-reported in aging autistic individuals, opening up questions about a possible link between ASD and an increased risk of Parkinson’s Disease. Utilizing MRtrix3, an image processing proof-of-concept pipeline was developed for the Autism and Brain Aging (ABA) lab to generate and visualize the brain’s structural connectivity network in these populations of interest. The pipeline provides the opportunity for white matter tractography analysis in the lab’s Aging in Autism study.

The corpus callosum is a core white matter structure that sits at the center of the brain, playing a role in both interhemispheric communication and the inhibition of hemispheric activity to promote lateralization. Structural connectivity is thought to underlie functional connectivity (FC), but cases of structural brain abnormalities allow for a better understanding of this relationship. Agenesis of the corpus callosum (AgCC) is a condition in which an individual is born without a corpus callosum. These individuals provide a unique opportunity to investigate ways in which the brain adapts its functional organization to the lack of interhemispheric structural connectivity, thereby providing unique insights into brain network organization within and between the two cerebral hemispheres. The present study uses resting-state functional magnetic resonance imaging (fMRI) to compare the network connectivity of an individual with AgCC without any significant comorbidities to a control group of neurotypical adults (n=30). Potential differences of FC within the default mode network and frontoparietal network, as well as FC between these networks and bilateral language networks were examined. The AgCC individual displayed significantly higher FC within the frontoparietal network (t(29)=1.84, p<0.05) and significantly lower FC between the default mode network and the right ventral language stream (t(29)=-1.81, p<0.05) compared to the control group. Further analyses suggest that the right hemisphere’s frontoparietal network is driving the significant difference between the case study and control group in the frontoparietal network. The stronger FC of the frontoparietal network may represent a compensatory strategy used to support lower overall levels of default mode network and dual stream language network connectivity. Overall, the findings suggest that decreased interhemispheric structural connectivity may lead to increased compensation via attention networks such as the frontoparietal network, and decreased right hemisphere language network involvement.

The steady influx of Venezuelan immigrants to the United States has resulted in the creation of a close-knit community of these immigrants in the city of Doral, Florida, now nicknamed Doralzuela given the strong imprint Venezuelan have left in this city. This study aimed at gaining understanding on how the process of immigration and settlement in the context has affected Venezuelan immigrants’ identity, their perception and use of English and Spanish in daily interactions, and how, or if, their bonds with the home country has affected their incorporation to the host society. The study followed a qualitative design. Eight semi-structured interviews were conducted and analyzed following Riessman’s (2008) notion of dialogic narrative analysis. Six themes emerged from the data; (re)configuration of the self, the role of social networks, negotiating identity through language, issues of assimilation, transnational identity, and Doralzuela, the new Venezuela. These themes were discussed, and multiple and distinct views on each theme were identified.

The label-feedback hypothesis (Lupyan, 2007, 2012) proposes that language modulates low- and high-level visual processing, such as priming visual object perception. Lupyan and Swingley (2012) found that repeating target names facilitates visual search, reducing response times and increasing accuracy. Hebert, Goldinger, and Walenchok (under review) used a modified design to replicate and extend this finding, and concluded that speaking modulates visual search via template integrity. The current series of experiments 1) replicated the work of Hebert et al. with audio stimuli played through headphones instead of self-directed speech, 2) examined the label feedback effect under conditions of varying object clarity, and 3) explored whether the relative prevalence of a target’s audio label might modulate the label feedback effect (as in the low prevalence effect; Wolfe, Horowitz, & Kenner, 2005). Paradigms utilized both traditional spatial visual search and repeated serial visual presentation (RSVP). Results substantiated those found in previous studies—hearing target names improved performance, even (and sometimes especially) when conditions were difficult or noisy, and the relative prevalence of a target’s audio label strongly impacted its perception. The mechanisms of the label feedback effect––namely, priming and target template integrity––are explored.

Cognitive deficits often accompany language impairments post-stroke. Past research has focused on working memory in aphasia, but attention is largely underexplored. Therefore, this dissertation will first quantify attention deficits post-stroke before investigating whether preserved cognitive abilities, including attention, can improve auditory sentence comprehension post-stroke. In Experiment 1a, three components of attention (alerting, orienting, executive control) were measured in persons with aphasia and matched-controls using visual and auditory versions of the well-studied Attention Network Test. Experiment 1b then explored the neural resources supporting each component of attention in the visual and auditory modalities in chronic stroke participants. The results from Experiment 1a indicate that alerting, orienting, and executive control are uniquely affected by presentation modality. The lesion-symptom mapping results from Experiment 1b associated the left angular gyrus with visual executive control, the left supramarginal gyrus with auditory alerting, and Broca’s area (pars opercularis) with auditory orienting attention post-stroke. Overall, these findings indicate that perceptual modality may impact the lateralization of some aspects of attention, thus auditory attention may be more susceptible to impairment after a left hemisphere stroke.

Prosody, rhythm and pitch changes associated with spoken language may improve spoken language comprehension in persons with aphasia by recruiting intact cognitive abilities (e.g., attention and working memory) and their associated non-lesioned brain regions post-stroke. Therefore, Experiment 2 explored the relationship between cognition, two unique prosody manipulations, lesion location, and auditory sentence comprehension in persons with chronic stroke and matched-controls. The combined results from Experiment 2a and 2b indicate that stroke participants with better auditory orienting attention and a specific left fronto-parietal network intact had greater comprehension of sentences spoken with sentence prosody. For list prosody, participants with deficits in auditory executive control and/or short-term memory and the left angular gyrus and globus pallidus relatively intact, demonstrated better comprehension of sentences spoken with list prosody. Overall, the results from Experiment 2 indicate that following a left hemisphere stroke, individuals need good auditory attention and an intact left fronto-parietal network to benefit from typical sentence prosody, yet when cognitive deficits are present and this fronto-parietal network is damaged, list prosody may be more beneficial.

This thesis examines the narratives and meta-commentary of Indonesian users of English about their English as a Second Language (ESL) experiences. It approaches interview data with ten Indonesian second language (L2) speakers of English from a narrative analysis/inquiry perspective. Each interview was transcribed according to a modified set of discourse analysis (DA) transcription conventions, then coded by the researcher. The first research question addressed what linguistic devices members of this population used to achieve cohesion and coherence in their narratives, and the second research question examined how members of this population portrayed their L2 selves in their narratives. The data yielded 21 linguistic devices that fell into three levels of frequency. Connectives, discourse markers, and repetition were by far the most common linguistic devices, followed by adverbials, embedded clauses, intensifiers, and the word like (non-comparison uses), which were somewhat frequent linguistic devices. The data also showed that participants constructed their L2 selves using three main categories: agency, identity, and perceptions of English and the U.S.. In regard to identity, participants invoked membership categorization, where they portrayed their identities in relation to other individuals. The study concludes with suggestions for future research, especially relating to Indonesian L2 users of English.

The activation of the primary motor cortex (M1) is common in speech perception tasks that involve difficult listening conditions. Although the challenge of recognizing and discriminating non-native speech sounds appears to be an instantiation of listening under difficult circumstances, it is still unknown if M1 recruitment is facilitatory of second language speech perception. The purpose of this study was to investigate the role of M1 associated with speech motor centers in processing acoustic inputs in the native (L1) and second language (L2), using repetitive Transcranial Magnetic Stimulation (rTMS) to selectively alter neural activity in M1. Thirty-six healthy English/Spanish bilingual subjects participated in the experiment. The performance on a listening word-to-picture matching task was measured before and after real- and sham-rTMS to the orbicularis oris (lip muscle) associated M1. Vowel Space Area (VSA) obtained from recordings of participants reading a passage in L2 before and after real-rTMS, was calculated to determine its utility as an rTMS aftereffect measure. There was high variability in the aftereffect of the rTMS protocol to the lip muscle among the participants. Approximately 50% of participants showed an inhibitory effect of rTMS, evidenced by smaller motor evoked potentials (MEPs) area, whereas the other 50% had a facilitatory effect, with larger MEPs. This suggests that rTMS has a complex influence on M1 excitability, and relying on grand-average results can obscure important individual differences in rTMS physiological and functional outcomes. Evidence of motor support to word recognition in the L2 was found. Participants showing an inhibitory aftereffect of rTMS on M1 produced slower and less accurate responses in the L2 task, whereas those showing a facilitatory aftereffect of rTMS on M1 produced more accurate responses in L2. In contrast, no effect of rTMS was found on the L1, where accuracy and speed were very similar after sham- and real-rTMS. The L2 VSA measure was indicative of the aftereffect of rTMS to M1 associated with speech production, supporting its utility as an rTMS aftereffect measure. This result revealed an interesting and novel relation between cerebral motor cortex activation and speech measures.
