Word Learning in Deaf Children Using Eye-tracking and Behavioral Measures

Mutual exclusivity is a word learning constraint in which the learner assumes that a given word refers to only one category of objects. In spoken languages, mutual exclusivity has been demonstrated in monolingual children as young as 17 months and cross-linguistically, while multilingual learners show an attenuated mutual exclusivity bias. Mutual exclusivity has not been robustly demonstrated in deaf children acquiring American Sign Language (ASL). Further, it is unclear if mutual exclusivity applies to those learning both a signed and a spoken language. Like unimodal bilinguals, bimodal bilingual (BiBi) children learn two words for an object, but these words are separated by modality. A BiBi child could therefore assume that all objects have two words (like unimodal bilinguals) or that all objects have one spoken word and one sign (within-modality mutual exclusivity). The goals of the current study are to demonstrate mutual exclusivity in monolingual deaf children acquiring ASL, and to determine if BiBi deaf children utilize mutual exclusivity within each modality.

A Study to Evaluate the PK and PD of IM or SQ Injections of Levonorgestrel Butanoate (LB) for Femal1

This is a Phase I multicenter, open-label, dose-ranging, three-dose PK and PD study of injectable LB administered as an IM or SQ injection at 40 mg, and subsequently at 50mg SQ and then 60 mg SQ depending on the preliminary pharmacokinetic and pharmacodynamic results obtained with 40 mg dosing. expand

The purpose of this study is to conduct a randomized clinical trial for an innovative intervention entitled "Mastering the World of Work" (MWW). MWW aims to improve the employment outcomes of individuals with psychiatric disabilities who experience metacognitive deficits. Metacognitive deficits are represented in diminished capacity to form an integrated sense of self and others and respond to challenges in life. The randomized trial (N=60) will be conducted with recipients of Supported Employment (Individual Placement and Support) services at the Mental Health Center of Greater Manchester, in Manchester, NH. Given COVID-19 safety considerations, the MWW intervention will be delivered in a hybrid manner depending on the preferences of both clinicians and clients at the MHCGM at any given point of the study. The feasibility of remote delivery of the intervention has been established as part of a pilot study conducted at BU CPR. Thus, clinicians may deliver the intervention using HIPAA-complaint ZOOM connection and/or in person. The assessments will be administered at baseline, 6, 12, and 18 months post baseline remotely by BU staff using a HIPAA-complaint ZOOM connection. The RCT will establish preliminary evidence about the incremental effectiveness of the MWW intervention to improve the employment outcomes of individuals with metacognitive deficits who receive high fidelity IPS services. Study participants randomized to the control condition will receive IPS services as usual.

TRIAD Appendicitis Decision-making Surveys

While appendectomy has been the main treatment of appendicitis for over 100 years, recent European studies found that, at least among highly selected patients, antibiotics alone can be an effective alternative. Surgeons and patients alike have a difficult time deciding if surgery or antibiotics are the best choice to treat appendicitis. The goal of the TRIAD is to evaluate the patients who are a part of the TRIAD implementation program and assess satisfaction and decisional regret for patients with appendicitis. This information will be used to inform the design of decision-support interventions to help patients improve their ability to make an informed decision in-line with their preferences and values.

Digital mental health interventions are a cost-effective and efficient approach to expanding the accessibility and impact of psychological treatments; however, little guidance exists for selecting the most effective program for a given individual. In the proposed study, decision rules will develop for selecting the digital program that is most likely to be the optimal intervention for each user. These treatment recommendations can be implemented in the context of large healthcare delivery systems to improve the delivery of digital mental health interventions at scale. The overarching aim of the current study is to better understand for whom and how leading digital interventions work in a large healthcare setting. The study builds on the existing literature and follows expert recommendations by using machine learning (ML) methods to develop precision treatment rules (PTRs) for three leading digital interventions for emotional disorders (e.g., anxiety, depression, and related mental health disorders). Specifically, ML methods will be used to develop PTRs to optimize clinical outcomes and associated intervention engagement. This study will leverage a unique partnership between Boston University (BU), SilverCloud Health (SC)--a leading provider of digital mental health care--and Kaiser Permanente (KP)--one of America's leading health care providers. A clinical trial (RCT) will be conducted to evaluate the relative effectiveness of three distinct empirically supported digital mental health interventions (from SC's existing library of programs) in a sample recruited from KP primary care and other clinical settings. Data from this trial will be used to develop theoretically and empirically informed, reliable selection algorithms for managing treatment delivery decisions. Algorithms will be validated in a separate "holdout" dataset by examining whether allocation to predicted optimal treatment is associated with superior outcomes compared to allocation to a non-optimal treatment. The role of user engagement will be determined, and other mechanisms in treatment outcome.

The purpose of this study is to investigate several approaches for improving spatial perception and speech intelligibility in multitalker listening situations for hearing-aid users. The hypotheses are that spatial perception and speech intelligibility will be improved by (1) increased high-frequency audibility, (2) speech envelope enhancement, and/or (3) appropriate sound image externalization.
