An experiment was performed in which a small target, viewed foveally, underwent 1 degree lateral shifts at quasi-random intervals. Subjects' response latency to the shift was investigated under various square-wave flicker conditions and compared to non-flickering conditions. Flicker was found to raise latencies, the effect peaking between 8 and 14 Hz. Under(More)
5 We investigate the validity of the popular coupled-continuum pipe-flow 6 (CCPF) model for flow in a karst aquifer. The (Navier) Stokes-Darcy model 7 is used as the " true model " for calibrating the exchange coefficient in the 8 CCPF model by minimizing the relative differences between results from the 9 two models or at least by having those differences(More)
Response times to a change in location of a small, low contrast target in a uniform flickering field were investigated under a range of flicker modulation depths. Increasing depth of modulation gave an increased response time for modulation depths from 0% (no flicker, to approx. 35%. Further increases in modulation depth had only a marginal effect on(More)
