Basis of the horizontal-vertical illusion.
Three experiments were designed to determine the basis of the horizontalvertical (HV) illusion using an L figure. Experiment I showed that there were no differences in the size of the effect in darkness, semidarkness, and in the light, a result contrary to the visual field explanation. In Exp. II the figure was viewed in the dark with 5s upright and recumbent, and in Exp. Ill the L figure was o...
متن کاملAnalysis of individual variations in the classical horizontal-vertical illusion.
In the horizontal-vertical illusion (HVI), the length of the vertical line is overestimated, whereas in the bisection illusion (BI), the horizontal bisecting line is expected to be overestimated. Here, only half of our 22 observers showed the expected BI, whereas the other half underestimated the bisecting line. Observers also differed in their judgments of the strength of the HVI: The HVI was ...
متن کاملAbsence of the horizontal-vertical illusion in haptic space.
An earlier experiment showed that the so-called horizontal-vertical (HV) illusion with an L is a function of the retinal meridians with which the two lines correspond. This finding indicated that the illusion is specifically visual and, therefore, unlike other geometrical illusions, would not be expected to occur haptically. The experiment showed that, as found in earlier studies, a large hapti...
متن کاملA simple model of the vertical–horizontal illusion
In spite of being one of the most elementary visual effects, the vertical-horizontal illusion is still poorly understood. We provide here a simple quantitative model to describe the overestimation of the vertical segment relative to the horizontal one. The model also includes a necessary factor related to the effect of bisecting a line on the under-estimation of its length. These two factors, o...
متن کاملHorizontal-vertical illusion in mental imagery: quantitative evidence
The present study had two main goals: (1) to investigate the difference between perception and mental imagery using a visual illusion as a stimulus; (2) to inspect gender related differences in perception and imagery. Our main hypothesis, that there would be no differences between perception and mental imagery, was motivated by previous neuroimaging data. Unlike these neuroimaging studies that ...
