Agreement in future studies on two fronts could have particular impact on our ability to integrate and synthesize the
findings. The first is an increased level of standardization in the choice of pre- and post-training assessments. At present, there is an emerging consensus for the inclusion of cognitive control (e.g., Stroop) and general fluid intelligence assessments, two skills that are evaluated in several training studies. Interestingly, there are instances of both successful and failed transfer for each construct. We suggest that these two constructs may thus serve as a useful benchmark for comparison of different training protocols, and we encourage their inclusion (preferably using normative instruments) in future studies in order to support such comparison.
