Combining cues while avoiding perceptual conflicts

A common assumption in cue combination models is that small discrepancies between cues are due to the limited resolution of the individual cues. Whenever this assumption holds, information from the separate cues can best be combined to give a single, more accurate estimate of the property of interest. We examined whether information about the...

Quantifying the intelligibility of speech in noise for non-native listeners

Simultaneous exposure to ethyl benzene and noise: Synergistic effects on outer hair cells

The effects on hearing of simultaneous exposure to the ototoxic organic solvent ethyl benzene and broad-band noise were evaluated in rats. The effects of three ethyl benzene concentrations (0, 300 or 400 ppm) and three noise levels (95 or 105 dBlin SPL or background noise at 65 dBlin SPL) and all their combinations were investigated for a 5 day...

Ethyl benzene-induced ototoxicity in rats: A dose-dependent mild-frequency hearing loss

Rats were exposed to ethyl benzene at 0, 300, 400 and 550 ppm for 8 hours/day for 5 consecutive days. Three to six weeks after the exposure, auditory function was tested by measuring compound action potentials (CAP) in the frequency range of 1-24 kHz and 2f1-f2 distortion product otoacoustic emissions (DPOAEs) in the frequency range of 4-22.6...

Influence of body roll on visually induced sensations of self-tilt and rotation

We investigated whether illusory self-tilt and self-motion induced by rotation of a visual scene about the subject's roll-axis was enhanced by actual rotation of the subject during acceleration of the visual scene. Rotation of the subject to a tilt of 15° was with or without a delay between initial rotation (onset) and subsequent return to the...

Motion sickness amelioration induced by prism spectacles

A side effect of the prescription of prism glasses according to the principle of Utermöhlen to improve mechanical reading skills of certain types of learning disabled children, was the alleviation of car sickness. Besides a decrease in reported symptoms after prescription of these glasses, the effect is quantified by a decrease in estimated...
