More accurate size contrast judgments in the Ebbinghaus Illusion by a remote culture.
The Ebbinghaus (Titchener) illusion was examined in a remote culture (Himba) with no words for geometric shapes. The illusion was experienced less strongly by Himba compared with English participants, leading to more accurate size contrast judgments in the Himba. The study included two conditions of inducing stimuli. The illusion was weaker when the inducing stimuli were dissimilar (diamonds) t...
متن کاملAffective stimulus properties influence size perception and the Ebbinghaus illusion
In the New Look literature of the 1950s, it has been suggested that size judgments are dependent on the affective content of stimuli. This suggestion, however, has been 'discredited' due to contradictory findings and methodological problems. In the present study, we revisited this forgotten issue in two experiments. The first experiment investigated the influence of affective content on size pe...
متن کاملAttractive Contours of the Ebbinghaus Illusion.
There is debate as to whether or not the Ebbinghaus illusion is driven by high-level cognitive size contrast mechanisms as opposed to low-level biphasic contour interactions. In this study, we examine the variability in effects that are shared between this illusion and a different illusion that cannot be explained logically by a size contrast account. This comparison revealed that nearly one qu...
متن کاملJudgmental model of the Ebbinghaus illusion.
Two experiments studied the Ebbinghaus illusion as a function of four stimulus variables: the size of the context circles, the number of context circles, the distance between the context circles and the center circle, and the size of the center circle. The results provided a quantitative test of a judgmental model that considers the Ebbinghaus illusion to be comparative in nature. The context c...
متن کاملRelative Size Discrimination and Perception of the Ebbinghaus Illusion in a Bottlenose Dolphin (Tursiops truncatus)
Dolphins are known to show similarities to humans with respect to a range of visual perceptual tasks, but it is not well understood how dolphins perceive objects through vision. In this study, we tested the relative size discrimination of visual stimuli in a bottlenose dolphin (Tursiops truncatus) in order to examine whether dolphins could solve size discrimination problems using relative size ...
