There are other striking examples of visual processes being tailored to an organism’s tasks. Milner and Goodale (1995) have proposed interacting but distinct visual pathways involved in visual identification/recognition of an object and reaching for that object. One confirmed prediction of the idea that perceptual processes are tuned to the currently relevant actions is that visual systems engaged in identification/recognition and reaching should not always show the same pattern of sensitivity to illusions (Aglioti et al., 1995 and Bruno and Franz, 2009). While verbally reported size judgments for a central circle are heavily influenced by the sizes of surrounding circles, grasps for the central circle are relatively unaffected. This is a plausible pattern if one assumes that successful grasps depend on metric calculations based on the target itself, whereas explicit perceptual judgments about that target can sometimes benefit from determining its relation to other objects (Franz, 2001).
