Warning Signals Go Multisensory
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 effecti...
متن کاملWarning signals influence motor processing.
When observers initiate responses to visual targets, they do so sooner when a preceding stimulus indicates that the target will appear shortly. This consequence of a warning signal may change neural activity in one of four ways. On the sensory side, the warning signal may speed up the rate at which the target is registered by the brain or enhance the magnitude of its signal. On the motor end, t...

5 Figures 28 Pages (including references and figure captions) Summary When observers initiate responses to visual targets, they do so sooner when a preceding stimulus indicates that the target will appear shortly. This consequence of a warning signal may change neural activity in one of four ways. On the sensory side, the warning signal may speed up the rate at which the target is registered by...
متن کاملWarning signals and predator-prey coevolution.
Theories of the evolution of warning signals are typically expressed using analytic and computational models, most of which attribute aspects of predator psychology as the key factors facilitating the evolution of warning signals. Sherratt provides a novel and promising perspective with a model that considers the coevolution of predator and prey populations, showing how predators may develop a ...
متن کاملEarly warning signals in plant disease outbreaks
Correspondence Sirio Orozco-Fuentes Email: [email protected] Summary 1. Infectious disease outbreaks in plants threaten ecosystems, agricultural crops and food trade. Currently, several fungal diseases are affecting forests worldwide, posing a major risk to tree species, habitats and consequently ecosystem decay. Prediction and control of disease spread are difficult, mainly ...
