The effect of centesimal prismatic lenses on attention orienting processes: neuroscientific evidence

Prismatic Adaptation has different clinical applications but, given its association with attention orienting mechanisms, it might hold a potential even for neurocognitive empowerment. The present study aimed at investigating the empowerment effect of a protocol based on centesimal prismatic lenses (SiXDEVICE™) on attention orientation processes and their electrophysiological markers (event-related potentials, ERPs) by using a spatial cueing paradigm. Twenty participants were divided into an experimental group, training with SiXDEVICE™, and an active control group, performing traditional visual training. The comparison of pre/post-training performance measures and ERP markers of attention orienting – namely, the P300 component – highlighted qualitatively different patterns of performance modulation between the groups and a significant reduction of P300 amplitude over parietal areas in response to invalid cue trials in experimental participants. Preliminary results hint at the potential of the tested optical device and protocol as supportive tools to foster attention skills even in healthy people.
