Unilateral neglect and disambiguation of the Necker cube.
Three groups of patients (right brain-damaged patients with or without left neglect, and left brain-damaged patients) and a group of healthy subjects, matched for age and educational level to the three groups of patients, were asked to report which of the two frontal surfaces of Necker cubes oriented in four different ways looked, at first sight, nearer to the viewer. The extent to which, and t...
متن کاملOrganizational determinants of subjective contour: the subjective Necker cube.
With specially arranged inducing elements on a white surface of uniform luminosity, a phenomenally complete Necker cube can be seen in any array where only the 'corners' of the cube are physically represented. The subjectively seen bars of the cube disappear when the inducing 'discs' are seen as 'holes' in an interposing surface, through which the corners of a partially occluded cube are viewed...
متن کاملDisambiguation of Necker cube rotation by monocular and binocular depth cues: Relative effectiveness for establishing long-term bias
The apparent direction of rotation of perceptually bistable wire-frame (Necker) cubes can be conditioned to depend on retinal location by interleaving their presentation with cubes that are disambiguated by depth cues (Haijiang, Saunders, Stone, & Backus, 2006; Harrison & Backus, 2010a). The long-term nature of the learned bias is demonstrated by resistance to counter-conditioning on a consecut...
متن کاملNeural generators of ERPs linked with Necker cube reversals.
Multistable perception occurs when a single physical stimulus leads to two or more distinct percepts that spontaneously switch (reverse). Previous ERP studies have reported reversal negativities and late positive components associated with perceptual reversals. The goal of the current study was to localize the neural generators of the reversal ERP components in order to evaluate their correspon...
متن کاملAssessment of unilateral neglect.
U nilateral neglect (ULN) (or “neglect”) is a common behavioral syndrome in patients following stroke. The reported incidence of ULN varies widely from 10%1 to 82%2 following right-hemisphere stroke and from 15%3 to 65%2 following left-hemisphere stroke. Reasons for the variability in the published rates of occurrence of ULN after stroke include subject selection criteria, lesion site, and the ...
