Warning Signals Influence Motor Processing [PDF]

Journal of Neurophysiology, 2007
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 ...

Effects of Bright Light Treatment on Psychomotor Speed in Athletes

Frontiers in Physiology, 2014
Purpose: A recent study suggests that transcranial brain targeted light treatment via ear canals may have physiological effects on brain function studied by functional magnetic resonance imaging (fMRI) techniques in humans.

Early Warning Signals of Military Coups [PDF]

Obrana a strategie (Defence & Strategy), 2020
The following paper focuses on the identification of basic early warning signals of military coups. The primary purpose is to use a theoretical framework of coups and create a list of factors that increase the probability of upcoming or ongoing military coups.

The speeding of voluntary reaction by a warning signal [PDF]

Psychophysiology, 2009
AbstractWarning signals can shorten reaction time (RT) via either a top‐down mechanism, temporal attention, or a bottom‐up one, phasic arousal. The goal of this review article is to identify the locus at which these processes influence RT. Electrophysiological and behavioral evidence indicate that the chronometric locus for both modulatory effects lies

A Signal-Detection Theory Based Perspective on Design of Warning

, 1998
The effects of warnings are analyzed using a distributed signal-detection theory model. It is established that selectivity always increases effectiveness.

Anticipating regime shifts by mixing early warning signals from different nodes

Nature Communications
Real systems showing regime shifts, such as ecosystems, are often composed of many dynamical elements interacting on a network. Various early warning signals have been proposed for anticipating regime shifts from observed data. However, it is unclear how

Multi-indicator precursor warning method for gas-bearing coal rock fracture based on charge signals

Meitan kexue jishu
To address the challenge of accurate precursor charge signal warning for gas-bearing coal rock dynamic disasters, a comprehensive warning method based on multi-indicator charge signals for gas-bearing coal rock failure is proposed.

Balance of payment crises in emerging markets: how early were the “early” warning signals? [PDF]

Although many papers have already proposed empirical models of currency crises, the timing of such crises has received relatively little attention so far.
