Does a monocularly presented size-contrast illusion influence grip aperture?
The present study tested the idea that if subjects rely more on scene-based pictorial cues when binocular cues are not available, then both their perceptual judgements and their grasp might be influenced by pictorial illusions such as the Ebbinghaus (Titchener) Circles Illusion under monocular viewing conditions. Under binocular viewing conditions, subjects were always able to scale their grip ...
متن کاملWhy We Thought That Action Mind-Sets Affect Illusions of Control
Gollwitzer and Kinney (1989) proposed the following hypothesis: People who ponder a goal decision (i.e., to either pursue Goal A or B, or to pursue either Goal A or stay passive) develop a deliberative mind-set that allows them to accurately assess whether a desired outcome can be controlled by their actions or not, whereas people who are planning the pursuit of a chosen goal develop a mind-set...
متن کاملVisual illusions affect planning but not control.
Much debate has arisen over how to account for the pattern of effects of visual illusions on action - that is, the findings that illusions affect actions in some circumstances but not others. I propose that this pattern can best be explained by postulating that visual illusions affect the planning of actions but do not affect the on-line control of actions. Strong evidence for this viewpoint co...
متن کاملA connectionist architecture for view-independent grip-aperture computation.
This paper addresses the problem of extracting view-invariant visual features for the recognition of object-directed actions and introduces a computational model of how these visual features are processed in the brain. In particular, in the test-bed setting of reach-to-grasp actions, grip aperture is identified as a good candidate for inclusion into a parsimonious set of hand high-level feature...
متن کاملAfterimage size is modulated by size-contrast illusions.
Traditionally, the perceived size of negative afterimages has been examined in relation to E. Emmert's law (1881), a size-distance equation that states that changes in perceived size of an afterimage are a function of the distance of the surface on which it is projected. Here, we present evidence that the size of an afterimage is also modulated by its surrounding context. We employed a new vers...
