When the eye saccades to a group of eccentric targets, it tends to land in a position which can be loosely described as the center of gravity of the configuration. By using letter targets within strings of letters, it was shown in two experiments that this "global effect", that is, the influence of the non-target elements on saccade accuracy, can be(More)
In most normal visual search situations, the environment is filled with a variety of stimuli, and selection among possible saccade targets is necessary. Current theories of visuomotor mechanisms must take into account not only the classical 'retinal error' input signal, but also perceptual and decisional factors as well as task-specific strategies adopted(More)
