Manual reaction time (RT) and visual evoked potentials (VEP) were measured in motion
onset and offset detection tasks. A considerable homology was observed between the …

Prior studies have shown that an electrophysiological correlate of visual motion processing
can be found in the N2, a transient negativity occurring at about 200 ms in the visual evoked …

The relationship between cognitive processing stages and event-related potential
components has been extensively researched for single components, but even the simplest …

We compared visual evoked potentials and psychophysical reaction times to the onset of
first-and second-order motion. The stimuli consisted of luminance-modulated (first-order) …

We used a reaction-time paradigm to examine the extent to which motion detection depends
on relative motion. In the absence of relative motion, the responses could be described by a …

The possibility that the visual system is able to register unattended changes is still debated
in the literature. However, it is difficult to understand how a sensory system becomes aware …

Reaction times to motion onset were measured as a function of eccentricity of presentation.
These were compared with measurements of perceived speed at various eccentricities. For …

Movement detection thresholds were measured for varying exposures of a moving spot. A
tradeoff was found in which an increase in duration (T) was offset by a decrease in the …

The median of simple motor reaction (RT) to a flash parallels the latencies of visually evoked
potential (VEP) deflections if flash intensity is varied. However, mean and median reaction …

Motor processes partly determine reaction time (RT) in both choice reaction time and in
binary classification tasks. These latter tasks are popular in cognitive psychology because …
