Description
The ways in which human relationships are managed via language is a topic of particular interest in the area of sociolinguistics where work into the study of such topics as politeness, impoliteness, and rapport management have attempted to shed light on this phenomenon. This study examines two segments of extended discourse by President Alvaro Uribe of Colombia at the 2008 Summit of the Rio Group where he addressed a gathering of Rio Group members comprising heads of state from Latin American and Caribbean nations. Faced with serious accusations about his nation's military actions into Ecuador a few days before the meeting in question, Uribe engaged the group through two extended statements where he defended his government's actions. In these two segments of discourse Uribe changed his tone; it is this change that the present study attempts to describe in terms of modification to the effects of his discourse on the relationship between himself and the other interlocutors. To this end, an analysis is done classifying Uribe's utterances as polite, per Brown and Levinson's politeness model, and impolite, per Culpeper's impoliteness model. Additionally, Spencer Oatey's model of rapport management is used to classify Uribe's utterances according to their effect on the components of rapport. These classifications are examined alongside an analysis of factors related to rapport management such as frame, purpose of the exchange, and participants, for the purpose of understanding how these many factors work together to generate a changed effect to rapport. Of greatest significance in this study is the relationship between (im)politeness strategies and components of rapport. This dynamic provided an interesting way of examining (im)politeness in a new context, one that factored-in the effects of (im)politeness to the relationship between interlocutors. The study, as described above, showed that Uribe's change in tone was indeed a change to approach to rapport management characterized by an initial focus on the transactional and relational goals rapport component in the first of two segments, that then changed in the second part to a focus on face and association rights.

Description
Although pragmatic analyses based on empirical data have been conducted throughout most of the Spanish-speaking world, Central America remains the most underrepresented region. This study examines the pragmatic strategies used by female Spanish speakers of Nicaragua and Panama in an advice-giving context. The data consists of eighteen role-plays recorded in Masaya, Nicaragua and Panama City, Panama in June and July of 2011. In the role-play situation, the interlocutor (fixed-role) requests advice from the participant, her best friend, regarding a serious issue in her marriage. The participant's advice-giving strategies are classified according to a categorization adapted from Blum-Kulka's request strategy taxonomy. This allows for a statistical analysis of how these strategies correspond to the three elements of Spencer Oatey's rapport management approach: behavioral expectations, face sensitivities and interactional wants. The results indicate strong similarities between participants from Nicaragua and Panama, both electing to respect all components of the association principle and to violate the equity principle, especially its autonomy control component. These results suggest that, at least in this advice-giving context between intimates, both Nicaraguan and Panamanian Spanish speakers prefer to impose their opinions and suggestions rather than respect the person's right to be treated fairly (i.e. equity principle) as well as to maintain a rapport-enhancing orientation rather than preserve their right to associate with others (i.e. association principle). The results of the pragmatic analysis show similarities with other research on directives in the Spanish-speaking world, including empirical studies in the Dominican Republic, Cuba, Venezuela and Spain. Specifically, these cultures are all associated with direct strategies and less mitigation, positive politeness, conventional indirectness and high involvement.

Description
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.

Description
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.

Description
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.

Description
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.

Description
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.
