Abstract

Working memory is a process of great relevance during childhood due to its role in diverse complex skills. Like the rest of executive functions, it is highly sensitive to environmental influences, so it is assumed that it could be modified through targeted interventions. A large number of working memory training studies in children aim to achieve transfer effects both on this process and on those with which it is related. Although some promising results have been found, the efficacy of working memory training cannot be affirmed; methodological quality of studies is one of the main reasons for this. Compliance with basic methodological criteria (inclusion of a control group that must preferably be active, random assignment of participants to groups) has a great impact on the internal validity of the studies. Furthermore, the need to control for the effects of motivational factors associated with the intervention is added and emphasized. This study reviews the fulfillment of these criteria in process-based working memory training literature in children, analyzing its impact on internal validity. Limitations of the field in relation to the lack of compliance with the proposed criteria are discussed and alternatives are suggested in order to improve the quality of future studies.
