S. Runeson et al., Specificity is always contingent on constraints: Global versus individual arrays is not the issue, BEHAV BRAIN, 24(2), 2001, pp. 240
Stoffregen & Bardy's proposal that perceptual systems can use information d
efined across two or, more sensory domains is valuable and urgent in its ow
n right. However, their claim of exclusive validity for global-array inform
ation is superfluous and perpetuated for incorrect reasons. The seeming amb
iguities of individual arrays emanate from failures to consider relevant ec
ological constraints and higher-order variables.
