Prism adaptation improves representational neglect

Neuropsychologia, 2001
Previous work has shown that various symptoms of unilateral neglect, including the pathological shift of the subjective midline to the right, may be improved by a short adaptation period to a prismatic shift of the visual field to the right. We report here, in two neglect patients the improvement of imagery neglect after prism exposure.

Adaptation to Vertical Prism

Optometry and Vision Science, 1988
Patients with vertical heterophoria and a reduced ability to adapt to an induced vertical prism are appropriate patients for a vertical prismatic correction. A clinical method is presented for identifying those patients with a reduced ability to adapt to an induced vertical prism.

Prism adaptation and viewing distance

Ophthalmic and Physiological Optics, 1990
Previous studies have shown that subjects with normal binocular vision adapt to prism‐induced phorias. However, there are conflicting reports as to the amount of adaptation shown to horizontal prisms. Some investigations found a greater amount of adaptation to base out prisms compared with base in, whilst others found the reverse and one study found no

Intermanual Transfer of Prism Adaptation

Journal of Motor Behavior, 2008
The authors measured intermanual transfer in participants (N = 48) whose exposed or unexposed right or left hand was tested 1st after participants experienced prismatic displacement. Test order did not affect either participants' performance during prismatic exposure or the usual aftereffects, but transfer occurred only when the authors tested the ...

Interocular Effects in Prism Adaptation

Science, 1969
Monocular prism aftereffects were measured in three groups of subjects each of whom had walked about wearing a 20-diopter prism, base up, over the right eye and one of the following over the left eye: a diffusing screen, 0-diopter prism, or a 20-diopter prism, base down.

Cognitive Load and Prism Adaptation

Journal of Motor Behavior, 1992
Subjects wore goggles with prisms that laterally displaced the visual field (rightward by 11.4 degree) and with full view of the limb engaged in paced (2-s rate) sagittal pointing at either an implicit ("straight ahead of the nose") target (Experiment 1) or an explicit (positioned leftward by 11.4 degree) target (in Experiment 2).

Prism adaptation by mental practice

Cortex, 2013
The prediction of our actions and their interaction with the external environment is critical for sensorimotor adaptation. For instance, during prism exposure, which deviates laterally our visual field, we progressively correct movement errors by combining sensory feedback with forward model sensory predictions.

Prism Adaptation Without Binocular Vision

Optometry and Vision Science, 1990
The assumption that vergence adaptation to a prism could only take place during single binocular vision was investigated by having subjects wear a prism while fusion was dissociated. Adaptation was evaluated by its effect on lateral heterophoria. Dissociation and measurement of heterophoria were by means of an automated version of Duane's screen and ...

Preserved prism adaptation in bilateral optic ataxia: strategic versus adaptive reaction to prisms

Experimental Brain Research, 2004
To date the anatomical substrate(s) of prism adaptation remain(s) particularly debated, with two main candidates emerging from the literature: the posterior parietal cortex (PPC) and the cerebellum. The functional processes involved in the acquisition of the adaptive aftereffects also remain largely unknown. The main result shown here is that a patient
