Abstract:The question was investigated what the role of perceptual learning in a backward masking paradigm is and how perceptual learning evolves either due to feature sensitivity (Ahissar & Hochstein, 2004) or rather due to exogenous attention (Szpiro and Carrasco, 2015). EEG was used to measure spatial attention by focusing on lateralized activity in the alpha bands by computing lateralized power spectra (LPS). Different blocks were examined to study perceptual learning. However, no learning effect as well as no increase in attention was found. Reaction times of the participants actually were faster per block and SOAs. The missing learning effect was explained mostly by the short time coverage of the study. For future research a greater time coverage as well as multiple threshold values for the critical SOA are recommended.
