A matter of time: Improvement of visual temporal processing during training-induced restoration of light detection performance

Frontiers in Psychology, 2015
The issue of how basic sensory and temporal processing are related is still unresolved. We studied temporal processing, as assessed by simple visual reaction times (RT) and double-pulse resolution (DPR), in patients with partial vision loss after visual ...
