This article aims to investigate whether auditory stimuli in the horizontal plane, particularly originating from behind the participant, affect audiovisual integration by using behavioral and event-related potential (ERP) measurements. In this study, visual stimuli were presented directly in front of the participants, auditory stimuli were presented at one location in an equidistant horizontal ...

Modern driver assistance systems make increasing use of auditory and tactile signals in order to reduce the driver's visual information load. This entails potential crossmodal interaction effects that need to be taken into account in designing an optimal system. Here we show that saccadic reaction times to visual targets (cockpit or outside mirror), presented in a driving simulator environment ...

PURPOSE Continuous performance tasks (CPTs) are used to measure individual differences in sustained attention. Many different stimuli have been used as response targets without consideration of their impact on task performance. Here, we compared CPT performance in typically developing adults and children to assess the role of stimulus processing on error rates and reaction times. METHOD Parti...

THE SPATIOTEMPORAL WINDOW OF INTEGRATION HAS BECOME A WIDELY ACCEPTED CONCEPT IN MULTISENSORY RESEARCH: crossmodal information falling within this window is highly likely to be integrated, whereas information falling outside is not. Here we further probe this concept in a reaction time context with redundant crossmodal targets. An infinitely large time window would lead to mandatory integration...

results our study showed that the sensitivity and specificity of taqman real time pcr was 96% and 95% respectively. these values were 89% and 90, 38% and 100%, 6% and 100% for pcr, culture and microscopy, respectively. conclusions our study showed that sensitivity of taqman real time pcr was higher that pcr, culture and microscopy but specificity of culture and microscopy was more than pcr and ...

To investigate the neural substrates of the perception of audiovisual speech, we conducted a functional magnetic resonance imaging study with 28 normal volunteers. We hypothesized that the constraint provided by visually-presented articulatory speech (mouth movements) would lessen the workload for speech identification if the two were concordant, but would increase the workload if the two were ...

in an attempt to assess objectively the integrity of the auditory pathways in 30 patients with definite multiple sclerosis (ms), an audiometric evaluation was performed and auditory brainstem responses (abrs) were obtained. stressing the auditory system by increasing the stimulation rate showed some enhancement in the identification of ms. 24 (ro%) patients had an abnormal abr along with clinic...

The saccadic response to a suddenly appearing visual target stimulus is faster when an accessory auditory stimulus is presented in its spatiotemporal proximity. This multisensory facilitation of reaction time is usually considered a mandatory bottom-up process. Here, we report that it can be modulated by the predictability of the target location provided by an accessory stimulus, thereby indica...

An apparatus for the measurement of reaction time to both visual and auditory stimuli with a provision to vary intensity of stimuli and with facility for lateralisation of sound to the right or left ear has been described.

To date, no detailed examination of the pattern of change in reaction time performance for different sensory modalities has been conducted across the circadian cycle during sleep deprivation. Therefore, we compared sustained auditory and visual attention performance during 40h of sleep deprivation assessing multiple metrics of auditory and visual psychomotor vigilance tasks (PVT). Forty healthy...
