Speeding Up Reaction Time with Invisible Stimuli

Speeding Up Reaction Time with Invisible Stimuli

Normal subjects react more quickly to a pair of visual stimuli than to a stimulus alone. This phenomenon is known as the redundant signal effect (RSE) and represents an example of divided visual attention in which signal processing is carried out in parallel to the advantage of response speed. A most interesting aspect of this phenomenon is that it can occur when one stimulus in a pair cannot b...

Speeding Up Network Simulations Using Discrete Time

We develop a way of simulating disease spread in networks faster at the cost of some accuracy. Instead of a discrete event simulation (DES) we use a discrete time simulation. This aggregates events into time periods. We prove a bound on the accuracy attained. We also discuss the choice of step size and do an analytical comparison of the computational costs. Our error bound concept comes from th...

Speeding Up the Response-Time Analysis of Tasks with Offsets

We present a method that enables an efficient implementation of the approximative response-time analysis for tasks with offsets presented by Tindell [11] and Palencia Gutierrez et al. [6]. The method allows for significantly faster implementations of schedulability tools. To have fast calculations of response-times is paramount in optimising tools that perform automatic configuration of systems...

Speeding-up Reinforcement Learning with

Human reaction time to negative contrast stimuli.

Simple motor reaction time (RT) to 100 percent negative contrast stimuli was measured for various background luminances as well as after bleaching a fraction of retinal photopigments. RT decreased to asymptotical value with the increase of background intensity. The intensity-dependent portion of RT behaved identically for 100 percent positive and negative contrast. Moreover, RT to 100 percent n...
