Abstract
ABSTRACT When asked to align an object to what is perceived as straight ahead under conditions of an asymmetrical retinal stimulation observers systematically err in the direction of the centre of stimulation. This effect is known as Roelofs (or Dietzel-Roelofs) effect. When asked to judge the position of an object relative to an external reference under related conditions of sensory asymmetry a systematical bias of the opposite direction is usually observed. This effect has been called induced Roelofs effect. Here, I suggest that these illusions result from different attentional states caused by sensory asymmetry that are accompanied by changes in low-level spatial coding. This approach interlinks earlier ideas on the Roelofs effects and recent research on spatial attention, and can provide new insights into the origin of these effects.
期刊介绍：
Visual Cognition publishes new empirical research that increases theoretical understanding of human visual cognition. Studies may be concerned with any aspect of visual cognition such as object, face, and scene recognition; visual attention and search; short-term and long-term visual memory; visual word recognition and reading; eye movement control and active vision; and visual imagery. The journal is devoted to research at the interface of visual perception and cognition and does not typically publish papers in areas of perception or psychophysics that are covered by the many publication outlets for those topics.
