Judging relative positions across saccades
When components of a shape are presented asynchronously during smooth pursuit, the retinal image determines the perceived shape, as if the parts belong to the moving object that the eyes are pursuing. Saccades normally shift our gaze between structures of interest, so there is no reason to expect anything to have moved with the eyes. We therefore decided to examine how people judge the separati...
متن کاملJudging distance across texture discontinuities.
Sinai et al (1998 Nature 395 497-500) showed that less distance is perceived along a ground surface that spans two differently textured regions than along a surface that is uniformly textured. We examined the effect of texture continuity on judged distance using computer-generated displays of simulated surfaces in five experiments. Discontinuities were produced by using different textures, the ...
متن کاملAllocation of attention across saccades.
Whenever the eyes move, spatial attention must keep track of the locations of targets as they shift on the retina. This study investigated transsaccadic updating of visual attention to cued targets. While observers prepared a saccade, we flashed an irrelevant, but salient, color cue in their visual periphery and measured the allocation of spatial attention before and after the saccade using a t...
متن کاملSaccades from torsional offset positions back to listing's plane.
Rapid eye movements include saccades and quick phases of nystagmus and may have components around all three axes of ocular rotation: horizontal, vertical, and torsional. In this study, we recorded horizontal, vertical, and torsional eye movements in normal subjects with their heads upright and stationary. We asked how the eyes are brought back to Listing's plane after they are displaced from it...
متن کاملInitial directions and landing positions of binocular saccades
Existing models for the generation of saccades predict fixed trajectories between start and landing positions of saccades. Experimental data show that saccades have rather variable trajectories. The objective of the present research is to quantify the variability in trajectories of binocular saccades and to test in how far spatial variability can be described by adding noise to components of ex...
