Mean and standard errors of P3b amplitude on Pz EEG channels in the Young and Old groups under different stimulation conditions. Virtual environments The P3b amplitude averaged across target stimuli is reported A Aisle; L living room; B bedroom. Target stimuli colors: The P3b amplitude obtained by target stimuli in W white, R red, and G green conditions are reported, as well as the amplitude of the positive response in the 300–600 ms time interval after F—frequent stimuli
