Attention and number processing:a study of event related potentials / 中华物理医学与康复杂志

Objective To investigate the effects of distractions on number processing using event-related potentials (ERPs). Methods ERPs were recorded in fourteen undergraduate students while they were asked to compare a heard number with the number "5" and judge whether its numerical value was larger or smaller than five. This task was carried out under a distracted attention (DA) condition and a focused attention (FA) condition. The reaction time and EEG signals were recorded during the experiment. Results There were significant differences between the reaction times in the different conditions (t26 = 3. 70,P
