Does illusory flickering result from rhythmic sampling of visual stimuli?
Approximately a century ago, the oscillatory character of human neural activity was revealed by the discovery of electroencephalographic (EEG) rhythms. Since then, numerous observations have helped to decipher the functional meaning of brain oscillations. Most of the studies have focused on the alpha rhythm (8 –13 Hz), whose strong spectral power is clearly modulated by visual stimulation, visu...
متن کاملMotion aftereffect with flickering test stimuli depends on adapting velocity
Temporal tuning property of motion aftereffect (MAE) with flickering test stimuli (flicker MAE) was examined. Using sinusoidal gratings of several spatial frequencies (SF), MAE strength was measured for various adapting temporal frequencies (TF). Unlike the traditional MAE with static test field, the results indicated that flicker MAE did not depend on TF. Rather, when plotted as a function of ...
متن کاملPerceived Speed of Colored Stimuli
The influence of contrast and color on perceived motion was measured using a speed-matching task. Observers adjusted the speed of an L cone contrast pattern to match that of a variety of colored test patterns. The dependence of speed on test contrast was the same for all test colors measured, differing only by a sensitivity factor. This result suggests that the reduced apparent speed of low con...
متن کاملConsumer Perception of Product Stimuli
Consumer perception of product value is central to all stages of the process of bringing products to markets, from design and manufacture to distribution and retail. As a result, product strategy needs to respect customer needs in order to achieve or retain competitive advantage in providing innovative and differentiated products. Increasingly however, markets are becoming saturated with homoge...
متن کاملPosition-based motion perception for color and texture stimuli: effects of contrast and speed
Motion can be perceived either through low-level, motion-energy detection or through tracking the change in position of features. Previously we have shown that, while luminance-based motion likely is detected with velocity-sensitive motion-energy units, patterns defined by texture or binocular disparity ('second-order' stimuli) were tracked by a position-sensitive mechanism (Seiffert & Cavanagh...
