Reply to Schooler Consistent Is Not Conclusive

In this reply, I address the major issues raised by Schooler in his commentary on my article. Although we probably disagree about some points, I suspect that we are in agreement that there is empirical evidence that can be interpreted as being consistent with some aspects of the mental-exercise hypothesis. However, from my perspective, the available evidence is far from conclusive with respect to mental exercise slowing the rate of age-related mental decline, and recognition of the current state of uncertainty on this issue will likely facilitate progress in identifying the role of mental activity and other moderators of mental aging.
