Description
The current study explores the extent to which different processing strategies affect comprehension accuracy and integration of information across multiple texts. Reading comprehension of single texts is a difficult task, in which the challenges are compounded by the need to integrate information across texts. Processing strategies, such as self-explanation and source-evaluation, help reduce the challenges that readers face when attempting to comprehend texts. Self-explanation has been a successful strategy for coherence-building processes in single text comprehension, but the benefits for supporting inter-textual comprehension have not yet been explored. Source-evaluation supports identification of different sources, which helps resolve inconsistencies between texts; yet it remains unclear whether sourcing alone supports comprehension within as well as between texts. Think-aloud is a strategy intended to encourage further processing of the text without providing any explicit comprehension strategy. The differences between these two strategies prompts questions regarding the adequacy of either strategy for supporting inferencing and integration within and across texts. In this study, participants (n=80) were randomly assigned to one of three strategy conditions: self-explanation, source-evaluation, or think-aloud. Students read four texts after which they completed three types of open-ended comprehension questions (i.e., textbase, intra-textual inference, and inter-textual inference), a source memory task, and individual difference measures. Prior knowledge and reading skill were strongly correlated (r = .65) and showed moderate correlations (r = .31 to .60) with participants’ comprehension accuracy, total number of integrations within their responses, and their memory for sources. Participants were more likely to respond accurately and demonstrate integrations across texts for the text-based questions in comparison to the more challenging inference questions. There was a marginal effect of condition on comprehension question accuracy, wherein participants who self-explained responded more accurately than those who engaged in the think-aloud task. In addition, those in the self-explanation or source-evaluation conditions recalled more sources than those in the think-aloud condition. There were no significant differences in performance between the self-explanation and the source-evaluation conditions. Overall, the results of this study indicate that encouraging students to self-explain and/or evaluate sources while they read multiple documents enhances comprehension and memory for sources.

Proprioception and Manual Dexterity in Pianists, Reflected in Performance and a Review of Literature
Description
I performed Franz Liszt's Hungarian Rhapsody No. 2 and orally presented the findings of my written literature review. I addressed the relationship between the brain and muscles, and how complex neural networks develop in pianists. I focused on how proprioception, manual dexterity, somatosensory motor integration and fine motor function related to the technical aspects of my piano performance.

Description
Reading comprehension is a critical aspect of life in America, but many English language learners struggle with this skill. Enhanced Moved by Reading to Accelerate Comprehension in English (EMBRACE) is a tablet-based interactive learning environment is designed to improve reading comprehension. During use of EMBRACE, all interactions with the system are logged, including correct and incorrect behaviors and help requests. These interactions could potentially be used to predict the child’s reading comprehension, providing an online measure of understanding. In addition, time-related features have been used for predicting learning by educational data mining models in mathematics and science, and may be relevant in this context. This project investigated the predictive value of data mining models based on user actions for reading comprehension, with and without timing information. Contradictory results of the investigation were obtained. The KNN and SVM models indicated that elapsed time is an important feature, but the linear regression models indicated that elapsed time is not an important feature. Finally, a new statistical test was performed on the KNN algorithm which indicated that the feature selection process may have caused overfitting, where features were chosen due coincidental alignment with the participants’ performance. These results provide important insights which will aid in the development of a reading comprehension predictor that improves the EMBRACE system’s ability to better serve ELLs.

Description
String players have been identified as the most affected group of instrumentalists suffering from musculoskeletal disorders, and most of the problems are related to posture. The high prevalence of injuries among string players suggests that there is room in the music curriculum for a program tailored to this population and that can provide both immediate and long-term solutions. Pilates is a mind-body conditioning method of exercises and a philosophy that shares many similarities with string playing technique and performance, which suggests that its practice can be beneficial to improve not only the posture of string players but also various other areas. Studies about Pilates as a treatment show the varied areas in which Pilates can help, which are all of interest to instrumentalists. However, the application of Pilates into the music curriculum as a way to help string players improve awareness and reduce injuries has not yet been fully explored. This document addresses the similarities between Pilates and string playing, identifies postural tendencies of string players, and demonstrates how specific Pilates exercises can help counteract asymmetries, restore balance, and reduce the number of musculoskeletal injuries of string players. All anatomical drawings included in this document were adapted from other sources, as cited, or originally drawn by the author.

Description
A converging operations approach using response time distribution modeling was adopted to better characterize the cognitive control dynamics underlying ongoing task cost and cue detection in event based prospective memory (PM). In Experiment 1, individual differences analyses revealed that working memory capacity uniquely predicted nonfocal cue detection, while proactive control and inhibition predicted variation in ongoing task cost of the ex-Gaussian parameter associated with continuous monitoring strategies (mu). In Experiments 2A and 2B, quasi-experimental techniques aimed at identifying the role of proactive control abilities in PM monitoring and cue detection suggested that low ability participants may have PM deficits during demanding tasks due to inefficient monitoring strategies, but that emphasizing importance of the intention can increase reliance on more efficacious monitoring strategies that boosts performance (Experiment 2A). Furthermore, high proactive control ability participants are able to efficiently regulate their monitoring strategies under scenarios that do not require costly monitoring for successful cue detection (Experiment 2B). In Experiments 3A and 3B, it was found that proactive control benefited cue detection in interference-rich environments, but the neural correlates of cue detection or intention execution did not differ when engaged in proactive versus reactive control. The results from the current set of studies highlight the importance of response time distribution modeling in understanding PM cost. Additionally, these results have important implications for extant theories of PM and have considerable applied ramifications concerning the cognitive control processes that should be targeted to improve PM abilities.

Description
The notion that a singer’s voice is an expression of their personality serves as the catalyst for an examination of the relationship between the continuum of introversion and extraversion, and the pathologies of muscle tension dysphonia, vocal nodules, and performance anxiety. This paper begins with a brief introduction defining extraversion and introversion, followed by a review of personality studies identifying opera singers as primarily extraverted. Definitions of vocal nodules and muscle tension dysphonia are then given along with a list of recommended therapies. These elements tie in with two studies in speech pathology that suggest that behaviors of extraversion contribute to the development of vocal nodules, and behaviors of introversion contribute to muscle tension dysphonia and a higher laryngeal placement. Performance anxiety is shown to compound the behaviors that lead to vocal pathologies in singers. Additional therapies are recommended to address anxiety management in vocal lessons. Finally, since personality factors that contribute to vocal pathology are psychological, it is recommended that voice teachers refer their students to a psychotherapist for proper treatment.
