Abstract
Prism adaptation theory in unilateral neglect: motor and perceptual components
Highlights
Striemer and Danckert (2010a) suggest that prism adaptation (PA) has beneficial effects primarily on spatial attention and the motor components of neglect, and that the direct effects on visual neglect are insignificant
Striemer and Danckert’s (2010a) argument that PA primarily affects visuomotor and dorsal aspects of neglect, while leaving perceptual and ventral components of the syndrome mostly unaffected, underestimates the role of diagnosis and neuroanatomcial understanding of motor response deficits in unilateral neglect. Their main hypothesis is that PA improves visually guided actions but not perceptual biases that characterize neglect; this statement does not address the role of visual neglect in the therapeutic effects of PA
Even if the empirical findings of Striemer and Danckert (2010b) do not reveal positive effects on visual neglect, it is likely the deficit plays a passive role in improved directional motor response biases of unilateral neglect
Summary
Striemer and Danckert (2010a) suggest that prism adaptation (PA) has beneficial effects primarily on spatial attention and the motor components of neglect, and that the direct effects on visual neglect are insignificant.
