Training and Transfer Effects Achieved with N-Back Task in Older Subjects Evidenced with EEG

摘要

Working Memory (WM) and cognitive functions decrease with age. Although WM training has been extensively studied, transfer effects to other cognitive functions are still inconclusive. We examined whether 10 sessions of N-Back training could improve not only the trained task but also lead to significant transfer effects to similar cognitive functions (near-transfer), such as spatial memory, and to different cognitive functions, such as intelligence and attention (far-transfer). We analyzed behavioral, as well as electroencephalogram (EEG) data recorded during task performance. Our results showed significant differences in N-Back performance and near-transfer effects, but no evidence for far-transfer effects.
