Does executive control really play a crucial role in explaining age-related cognitive and neural differences?
Executive control, as a unitary function, cannot explain the age-related differences observed, which are more likely to reflect a general slowing of processes with aging. However, when we take into account the specific subprocesses of executive control, the one that seems to be particularly affected by aging is shifting, as revealed by the age-related alterations in the RON parameters.
