Masked stimuli can cause partial motor activation and prime responses to subsequent stimuli. Under certain conditions, a biphasic pattern appears, such that positive priming precedes a negative phase, which has been interpreted as evidence of an inhibitory mechanism that suppresses the motor activity caused by the prime. In this article, the authors report(More)
We provide quantitative measurements of night vision device (NVD) halos formed by light sources as a function of intensity and distance, describe a method to simulate their effects in the lab and present results from psychophysical experiments designed to analyze haloinduced errors in slope estimation. The effective halo generating potential of a point(More)
Night vision devices (NVDs) or night-vision goggles (NVGs) based on image intensifiers improve nighttime visibility and extend night operations for military and increasingly civil aviation. However, NVG imagery is not equivalent to daytime vision and impaired depth and motion perception has been noted. One potential cause of impaired perceptions of space(More)
