Table 1.
Mean response times (in ms; SD in parentheses) of the compatible, the incompatible, and the neutral conditions as well as the compatibility effects (incompatible–compatible; in ms; SE in parentheses; discrepancies due to rounding differences) for each SOA (147 versus 360 ms) × Motion Type (single-dot versus row-of-dots) × Age Group (middle-aged, old) condition. Additionally, the effects of young participants (MEDage = 22 years, ranging from 18 to 47) in the single-dot ([12], Exp. 1, 147 and 360 ms SOA conditions) and row-of-dots ([9], Exp. 3) conditions from experiments published in previous papers with the same conditions as in the current experiment are presented for a direct comparison.
