[15] [16] Similarly, increasing the duration of a stimulus available in a reaction time task was found to produce slightly faster reaction times to visual [15] and auditory stimuli, [17] though these effects tend to be small and are largely consequent of the sensitivity to sensory receptors.
Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action. S–R compatibility has been described as the "naturalness" of the association between a stimulus and its response, such as a left-oriented stimulus requiring a response from the left side of the body.
Simon wished to see if an alteration of the spatial relationship, relative to the response keys, affected performance. Age was also a probable factor in reaction time. As predicted, the reaction time of the groups increased based on the relative position of the light stimulus (age was not a factor). The reaction time increased by as much as 30% ...

The gunslinger effect applies to the initial reaction, not later limb control, but there is no trade-off between that early reaction and later targeting accuracy. [ 8 ] One study conducted at the University of Birmingham found that subjects moved 10% faster when reacting rather than acting with intention. [ 9 ]
The time course of the response priming effect described so far only holds for SOAs up to about 100 ms. For longer SOAs, the priming effect can increase further. Under some circumstances, however, a reversal of the effect can be observed where inconsistent primes lead to faster responses to the target than do consistent primes.
Stimulus onset asynchrony, the time that lapses between the presentations of the two stimuli, acts as the independent variable in this paradigm, and the reaction time to the second stimulus acts as the dependent variable. [1] Figure 1. Model of the central bottleneck accounting for the psychological refractory period.
But airflow meeting the leading edges is initially decelerated, so the free stream speed must be slightly greater than Mach 1 to ensure that all of the flow over the aircraft is supersonic. It is commonly accepted that the supersonic speed range starts at a free stream speed greater than Mach 1.3.
