The aging effects on subitizing were investigated using event-related brain potentials. Forty younger adults and 35 older adults perfonned an enumeration task in the subitizing range (i.e., 1 to 4 items). Results showed the slope of reaction times were steeper for older adults compared to younger adults, in dicating subitizing speed is affected by aging. Nl amplitudes increased with the number of items irrespective of age, suggesting that age-related decline of subitizing speed is independent of visual perceptual processes. In contrast, N2 amplitudes did not change with the number of items for younger adults, whereas the amplitudes decreased with increasing numbers of items for the older adults. These findings suggest that older adults might require attentive processes to enumerate items even in the subitizing range, whereas younger adults could enumerate the number of items by using preattentive information.
