Color Signals in Human

For more than 20 years there has been confusion and contradiction about whether and how the visual system can examine the motion of pure color patterns that contain no luminance variety. Three new papers have reported proof that, given their force, color patterns match luminance designs in the motion related sensations and utilitarian attractive resonance imaging signals. They evoke in people, and in the neural signs they inspire in the motion region of cortex of acting monkeys. This key aspect of the most seasoned and the most modern of cognitive neuroscience strategies decisively reject the proposal that color signs ...

4. Methodology As this experiment is considered as an improvement to the previous experiments, the other cars that might appear on these pictures were controlled by removing any other cars that appear on these pictures, except the approaching one. Then on the opposite lane, pictures of one or two cars were added to act as distracters. By this method, the road was transformed from an empty road, to either mild or high busy road creating another factor that can be tested (Traffic Density factor). This factor can be acted as more realistic (see figure 4.1). Figure 4.1 ...

Problem statement

Weber’s law is one of the most studied phenomenons in experimental psychology. Weber’s law gets used to study the response of human beings to stimuli in a quantitative manner. The law gets used to describe human sensation and perception (Goldstein, 2010). Weber’s law states that the just noticeable difference- JND, is a constant proportion of the original stimulus. This research proposes to measure the just noticeable difference thresholds of the participants using a psychophysical experimental procedure to prove Weber’s law (Rajamanickam, 2002). This research will aim to replicate Weber’s phenomenon using an adaptive psychophysical procedure in ...
