Quantifying Auditory Perceptual Learning Following Hearing Aid Fitting

The purpose of this study is to examine and relate physiological, behavioral, and self-perceived changes after a period of hearing aid use and as a function of auditory training. The project will focus on the following questions: 1)Is experience-related behavioral change in hearing aid performance reflected as a neurophysiologic change? 2)Does a neurophysiologic change occur prior to or in conjunction with an experience-related behavioral change? 3) Does behavioral training mod...

Spatial Neglect and Delirium After Stroke

The goal of this study is to understand what brain mechanisms become disrupted when stroke survivors experience delirium. Delirium is an acute reduction in attention and cognition, associated with poor recovery, longer hospitalization and even death. One major factor increasing the risk of delirium after stroke may be spatial neglect occurring after stroke on the right side of the brain. Spatial neglect affects awareness, orientation, and movement. The study will test the hypot...

A Model to Identify Specific Predictors of Spatial Neglect Recovery

This study examines methods to better predict improvement of a hidden disability of functional vision, spatial neglect, following stroke. Spatial neglect is a tendency to make visual judgment and movement errors mislocating the body and objects in space. The investigators are using specialized statistical methods to compute the proportion of improvement accounted for by personal characteristics of each stroke survivor, the proportion of improvement accounted for by the unique...

Spatial Skill Training for Robot-assisted Surgery

Surgical residents from a single tertiary medical center were divided into 2 groups. All residents performed 2 tasks on a Da Vinci robotic simulator system after which they were either given a real training session in spatial skills (study group) or shown a short presentation regarding robotic surgery. After training/watching the presentation, they repeated the for mentioned tasks on the robotic simulator. Improvement in surgeon performance, especially regarding tissue damage w...

Predicting Success With Hearing Aids

The primary complaint of individuals with hearing loss is difficulty understanding speech in the presence of background noise. Although hearing aids help individuals understand speech in background noise better, there is a high rate of hearing aid rejection in part due to continued difficulty understanding speech in complex listening situations. The results of this study may demonstrate that speech-in-noise test results can be a predictor of hearing aid success. The results of ...
