Detection of Dynamic Changes in Interaural Delay
The ability to detect a dynamic change in interaural time difference (ITD) was examined for rates of change from 3.125 to 32,000 s/s, for stimulus durations from 0.025 to 16 seconds, and for extent of change in interaural delay from 50 to 800 s. The stimulus was a sinusoidal tone of frequency f Hz presented to one ear and f f to the other ear, where f , the frequency difference, was varied to s...
متن کاملDetection of static and dynamic changes in interaural correlation.
This study examines the relation between a static and a dynamic measure of interaural correlation discrimination: (1) the just noticeable difference (JND) in interaural correlation and (2) the minimum detectable duration of a fixed interaural correlation change embedded within a single noise-burst of a given reference correlation. For the first task, JNDs were obtained from reference interaural...
متن کاملConcurrent motion detection based on dynamic changes in interaural delay.
The ability to detect a dynamic change in the interaural delay of a pure tone in the presence of a distracter tone of a different frequency was investigated in four conditions: (1) a control condition in which no distracter tone was present, (2) the distracter tone was stationary (fixed interaural delay), (3) the distracter had an interaural delay that changed in the same direction as that of t...
متن کاملThe influence of interaural stimulus uncertainty on binaural signal detection.
This paper investigated the influence of stimulus uncertainty in binaural detection experiments and the predictions of several binaural models for such conditions. Masked thresholds of a 500-Hz sinusoid were measured in an NrhoSpi condition for both running and frozen-noise maskers using a three interval, forced-choice (3IFC) procedure. The nominal masker correlation varied between 0.64 and 1, ...
متن کاملEffect of Phase-Encoding Reduction on Geometric Distortion and BOLD Signal Changes in fMRI
Introduction Echo-planar imaging (EPI) is a group of fast data acquisition methods commonly used in fMRI studies. It acquires multiple image lines in k-space after a single excitation, which leads to a very short scan time. A well-known problem with EPI is that it is more sensitive to distortions due to the used encoding scheme. Source of distortion is inhomogeneity in the static B0 field that ...
