Objective. Interferences from spatially adjacent non-target stimuli are known to evoke event-related potentials (ERPs) during non-target flashes and, therefore, lead to false positives. This phenomenon was commonly seen in visual attention-based brain-computer interfaces (BCIs) using conspicuous stimuli and is known to adversely affect the performance of BCI systems. Although users ...

Background: Evaluation tools are lacking for the identification of patients exhibiting pseudotinnitus. It was hypothesized that tinnitus loudness traces might show a separation between continuous and pulsed tones for participants exhibiting pseudotinnitus, that is, the "type V" pattern shown for threshold tracking among participants exhibiting pseudohypacusis. It was further hypothesized ...

Everyday walking is often interrupted by obstacles and changes in the environment that make gait a highly non-stationary process. This study introduces a novel measure, termed the step stability index (SSI), to quantify stepping stability under non-stationary walking conditions among older adults. This index is based on the ensemble empirical ...
