Safety Warning: Uncontrolled Reaction

Evaluating warning sound urgency with reaction times.

It is well-established that subjective judgments of perceived urgency of alarm sounds can be affected by acoustic parameters. In this study, the authors investigated an objective measurement, the reaction time (RT), to test the effectiveness of temporal parameters of sounds in the context of warning sounds. Three experiments were performed using a RT paradigm, with two different concurrent visu...

Tamoxifen for breast cancer prevention: safety warning.

HE A LT H A N D DR U G AL E RT S rate in the HRT group (42%), which would tend to underestimate treatment effects (beneficial and harmful), the trial showed a net harm. The trial did not address the benefit of short-term HRT in relieving postmenopausal symptoms, nor did it allow determination of the relative influence of estrogen versus progestin on disease event rates. A parallel WHI trial of ...

The speeding of voluntary reaction by a warning signal.

Warning 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 mainly within a narrow window at the center of the...

Intelligent Safety Regulation and Warning Method for Fishing Boat Security

The data mining is carried out for the historical data to investigate and analyze crucial factors related to the causes of accidents of fishing boats. The vital factors, especially shipping time, weather and manipulation, etc. are extracted as the input variables of a BP neural network to establish a safety warning model for fishing boats. In addition, the Particle Swarm Optimization (PSO) is e...
