Dissociating perceptual and motor effects of prism adaptation in spatial neglect
By Striemer, C., and Danckert, J. (2010a). Neuroreport 21, 436–441. doi: 10.1097/WNR.0b013e328338592f

Through a prism darkly: re-evaluating prisms and neglect
By Striemer, C., and Danckert, J. (2010b). Trends Cogn. Sci. 14, 308–316. doi: 10.1016/j.tics.2010.04.001

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. The main support for their influential hypothesis (e.g., Saj et al., 2013) comes from their own study (Striemer and Danckert, 2010b), but Saevarsson and Kristjánsson (2013) criticize their interpretations, and call for another possible evaluation of their data. Striemer and Danckert (2013) reply to this criticism; however, there are a number of controversial and fundamental issues that remain unresolved in this debate which future empirical studies need to consider, to explain “how PA remediates symptoms of neglect” (Striemer and Danckert, 2013, p. 2).
