Modelling Visual Change Detection and Identification under Free Viewing Conditions
We examined whether the abilities of observers to perform an analogue of a real-world monitoring task involving detection and identification of changes to items in a visual display could be explained better by models based on signal detection theory (SDT) or high threshold theory (HTT). Our study differed from most previous studies in that observers were allowed to inspect the initial display f...

1987 SUMMARY Thirty-jive volunteers responded when they first perceived an increase in apparent size o f a collimated, two-dimensional image of an Orbiter vehicle. The test variables of interest included the presence o f afixed angular reticle within the field of view (FOV); three initial Orbiter distances; three constant Orbiter approach velocities corresponding to 1.6, 0.8, and 0.4% of the in...
متن کاملVergence eye movements under natural viewing conditions.
PURPOSE To determine whether there are any fundamental differences in vergence dynamics under different viewing conditions, both in instrument space and free space. METHODS Symmetric vergence responses were measured for a variety of conditions under the traditional instrument space as well as the more natural free space viewing environment. Vergence eye movements were recorded objectively in ...
متن کاملAiming at a far target under different viewing conditions: visual control in basketball jump shooting.
Most research on visual search in aiming at far targets assumes preprogrammed motor control implying that relevant visual information is detected prior to the final shooting or throwing movements. Eye movement data indirectly support this claim for stationary tasks. Using the basketball jump shot as experimental task we investigated whether in dynamic tasks in which the target can be seen until...
متن کاملThe effect of retinal stabilization on anorthoscopic percepts under free-viewing conditions
Outline shapes were moved back and forth at .5 Hz behind a simulated narrow (10' or 15') slit without visible borders. Under free-viewing conditions observers reported spontaneous transitions between periods in which they saw a horizontally moving shape and periods in which they saw only vertically moving contour segments. Eye movements were monitored with a dual-Purkinje image eye-tracker. On ...
