Generalization of prism adaptation.
Journal of Experimental Psychology: Human Perception and Performance, 2006Prism exposure produces 2 kinds of adaptive response. Recalibration is ordinary strategic remapping of spatially coded movement commands to rapidly reduce performance error. Realignment is the extraordinary process of transforming spatial maps to bring the origins of coordinate systems into correspondence.

Predictors of prism response during prism adaptation. Prism Adaptation Study Research Group.
Journal of pediatric ophthalmology and strabismus, 1991Results of the Prism Adaptation Study (PAS) indicate that prism adaptation improves the success rate of strabismus surgery for patients with acquired esotropia. Patients who show a fusion response to the prisms benefit most from this preoperative treatment. This study analyzes the characteristics of those patients who were and were not prism responders

Dual Prism Adaptation: Calibration or Alignment?
Journal of Motor Behavior, 2003Dual adaptation to different amounts or directions of prismatic displacement, or both, can be acquired and maintained with little mutual interference. Associative recalibration of the regional task- or workspace, contingent on differentiation of distinguishing sensory information, can explain such adaptation.

Preserved prism adaptation in bilateral optic ataxia: strategic versus adaptive reaction to prisms
Experimental Brain Research, 2004To 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

Speculations on a Model of Prism Adaptation
Perception, 1974Arguments and evidence are presented that prism adaptation results in a third end state in addition to the ‘traditional’ components of ‘proprioceptive shift’ and ‘visual shift’. That is, under certain conditions (most importantly, ones involving error-corrective feedback), exposure to prism-displaced vision induces a motor-learning component, referred

Effect of prism adaptation on neglect hemianesthesia
Cortex, 2019Prism adaptation (PA) has proven to be effective in alleviating many signs of unilateral spatial neglect (USN). Generally, the principal improvement after PA treatment was found to be in the high-level cognitive function. Nevertheless, some evidence has also been found for it in somatosensory function.

Adaptation to Displacing Prisms in Human Infants
Perception, 1979This research reports a first attempt to study adaptation to laterally displacing prisms in human infants of ages six to ten months. Twenty infants were tested over four days under conditions similar to those used in adult adaptation studies. Evidence was found of vigorous adaptation when infants were exposed to base-right prisms under conditions of ...

Preoperative Prism Adaptation in Acquired Esotropia
Ophthalmologica, 201041 patients with acquired esotropia who did not have preoperative prism adaptation were compared to 50 patients who were prism-adapted prior to surgery. Surgical success was evaluated at a postoperative period of 6 months. 82% of the patients who responded to prism adaptation had a successful surgical result as compared to only 51% of the patients who ...

Prism Adaptation in Strabismus
Seminars in Ophthalmology, 1997Prisms have both diagnostic and therapeutic uses in strabismus. Many clinicians have popularized the use of prisms preoperatively to determine the target angle for surgery in esotropic patients. A review of the literature shows that preoperative prism adaptation, and the prism adaptation test is effective in predicting postoperative sensory and motor ...

Prism Adaptation Without Binocular Vision
Optometry and Vision Science, 1990ABSTRACT 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.
