Warning Signals Go Multisensory

چکیده
The potential use of non-visual warning signals to present spatial information to car drivers has been successfully demonstrated in several recent studies (Ho & Spence, submitted, in preparation; Ho, Tan, & Spence, submitted). Among the three types of spatial warning signals investigated (namely auditory, visual, and vibrotactile), spatial vibrotactile cues were found to be particularly effective in directing a driver’s visual spatial attention to potentially dangerous events on the road. We conducted the present study in order to examine the factors governing the relative effectiveness of auditory, visual, and vibrotactile warning signals. The speeded discrimination of warning signals presented in the various different modalities was investigated in order to explore whether the differences found in our previous research were a result of the relative speed with which people can detect warning signals presented in a given modality, or whether they were attributable to differences in the efficacy with which people can relate the warning signal to the subsequent visually-specified target driving events.

Multisensory processing of redundant information in go/no-go and choice responses.
In multisensory research, faster responses are commonly observed when multimodal stimuli are presented, as compared to unimodal target presentations. This so-called redundant-signals effect can be explained by several frameworks, including separate-activation and coactivation models. The redundant-signals effect has been investigated in a large number of studies; however, most of those studies ...
متن کاملIntegration of Bimodal Looming Signals through Neuronal Coherence in the Temporal Lobe
The ability to integrate information across multiple sensory systems offers several behavioral advantages, from quicker reaction times and more accurate responses to better detection and more robust learning. At the neural level, multisensory integration requires large-scale interactions between different brain regions--the convergence of information from separate sensory modalities, represente...

In this paper, we sketch a specific framework developed to describe and predict crossmodal effects in orienting responses. The time-window-of-integration (TWIN) model postulates that a crossmodal stimulus triggers a race mechanism in the early peripheral sensory pathways, then followed by a compound stage of converging subprocesses that comprise neural integration of the input and preparation o...

The most basic foundations of the self arguably lie in those brain systems that represent the body (Blanke and Metzinger 2009;Damasio 2000; Gallagher 2005; Jeannerod 2006; Knoblich 2002; Metzinger et al. 2007). The representation of the body is complex, involving the encoding and integration of a wide range of multisensory (somatosensory, visual, auditory, vestibular, visceral) and motor signal...
متن کاملPrinciples of multisensory behavior.
The combined use of multisensory signals is often beneficial. Based on neuronal recordings in the superior colliculus of cats, three basic rules were formulated to describe the effectiveness of multisensory signals: the enhancement of neuronal responses to multisensory compared with unisensory signals is largest when signals occur at the same location ("spatial rule"), when signals are presente...
