The impacts of training on change deafness and build-up in a flicker task Open
Performance on auditory change detection tasks can be improved by training. We examined the stimulus specificity of these training effects in behavior and ERPs. A flicker change detection task was employed in which spatialized auditory sce…

The Phase of Spontaneous Pre-stimulus EEG Oscillations Predicts Auditory Pattern Identification Open
Recent studies have shown that the power and phase of spontaneous pre-stimulus oscillations in the electroencephalogram (EEG) predict behavior on simple perceptual and cognitive tasks. Such findings suggest that pre-stimulus EEG may be use…

Learning-related improvements in auditory detection sensitivities correlate with neural changes observable during active and passive sound processing Open
Auditory detection can improve with training. Though the majority of theorists posit that such improvements relate to dynamics of selective attention, longer-term sensory plasticity may also play a role (e.g., increased cortical processing…

Enhanced auditory spatial performance using individualized head-related transfer functions: An event-related potential study Open
This study examined event-related potential (ERP) correlates of auditory spatial benefits gained from rendering sounds with individualized head-related transfer functions (HRTFs). Noise bursts with identical virtual elevations (0°–90°) wer…

In Ear to Out There: A Magnitude Based Parameterization Scheme for Sound Source Externalization Open
While several potential auditory cues responsible for sound source externalization have been identified, less work has gone into providing a simple and robust way of manipulating perceived externalization. The current work describes a simpl…

Response Techniques and Auditory Localization Accuracy Open
Auditory cues, when coupled with visual objects, have lead to reduced response times in visual search tasks, suggesting that adding auditory information can potentially aid Air Force operators in complex scenarios. These benefits are substa…

Virtual-Audio Aided Visual Search on a Desktop Display Open
As visual display complexity grows, visual cues and alerts may become less salient and therefore less effective. Although the auditory system’s resolution is rather coarse relative to the visual system, there is some evidence for virtual s…

Modeling Two‐Channel Speech Processing With the EPIC Cognitive Architecture Open
An important application of cognitive architectures is to provide human performance models that capture psychological mechanisms in a form that can be “programmed” to predict task performance of human–machine system designs. Although many …

Enhancing listener strategies using a payoff matrix in speech-on-speech masking experiments Open
Speech recognition was measured as a function of the target-to-masker ratio (TMR) with syntactically similar speech maskers. In the first experiment, listeners were instructed to report keywords from the target sentence. Data averaged acro…

Efficient Real Spherical Harmonic Representation of Head-Related Transfer Functions Open
Several methods have recently been proposed for modeling spatially continuous head-related transfer functions (HRTFs) using techniques based on finite-order spherical harmonic expansion. These techniques inherently impart some amount of sp…

Free-Field Localization Performance With a Head-Tracked Virtual Auditory Display Open
Virtual auditory displays are systems that use signal processing techniques to manipulate the apparent spatial locations of sounds when they are presented to listeners over headphones. When the virtual audio display is limited to the prese…
