1999), ERPs were also recorded that were consistent with the behavioral results: in fact, blind participants showed a steeper N1 gradient compared to the sighted controls for the peripheral but not for the central sounds, indicating a sharper attentional tuning mechanism operating at early spatial attention stages (first 100 ms) in blind individuals. , Bavelier, Tomann et al. 2000). It might be argued that differences in compensation for central and peripheral space are only indirect, rather reflecting an increase in the level of task difficulty, given that the task is more complex in the periphery than in the central visual field.

Blind subjects outperformed the sighted in both conditions; however, when the perceptual threshold of sighted and blind subjects was matched by adding noise, memory spans of the two groups overlapped. These data suggest that the blind subjects’ improved memory abilities depend on improved stimulus processing at an early stage of encoding, rather than on superior abilities at subsequent memory-related processes. In fact, improved sensory encoding may allow the sequencing and “chunking” that support better memory performance, a hypothesis also put forward by Raz et al.

2008) have compared blind and sighted individuals in a haptic angle-discrimination task, depending on both cutaneous and proprioceptive feedbacks. Participants had to actively scan with their right index finger pairs of two-dimensional angles, identifying the larger one. The same exploratory strategy (a single contour-following movement over the angles) was imposed on all subjects to ensure that all relied on the same information in making their sensory decisions.
