Experiments were performed to examine the temporal masking properties of multidimensional tactual stimulation patterns delivered to the left index finger. The stimuli consisted of fixed-frequency sinusoidal motions in the kinesthetic (2 or 4 Hz), midfrequency (30 Hz), and cutaneous (300 Hz) frequency ranges. Seven stimuli composed of one, two, or three spectral components were constructed at ea...

-Backward recognition masking refers to interference of a second masking tone with recognition of a target tone presented earlier in time. The degree of interference has been found to decrease as the length. of the silent interval separating the two tones increases. These results have been interpreted as representing interference of the masking tone upon the preperceptual storage and perceptual...

Recent research suggests that omnidirectional hearing aids are relatively ineffective at improving speech understanding in everyday conversational speech settings when the background noise contains both energetic and informational masking components. Energetic masking refers to situations where the peripheral (or neural) activity of the target is less than that of the masker, thus making the ta...

The COVID-19 virus entered our lives quickly, and almost no one could have predicted that several vaccines would be available less than a year after the public health emergency was declared. After ...

Binocular contrast interactions in human vision were studied psychophysically. Thresholds were obtained for sinewave grating stimulation of the right eye in the presence of simultaneous masking gratings presented to the right eye (monocular masking) or left eye (dichoptic masking). In the first experiment, thresholds were measured at 0.25, 1.0, 4.0, and 16.0 cycle per degree (cpd) as a function...
