Working Memory Training in Children: A Review of Basic Methodological Criteria.

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Neuroscience

Background:

• Working memory is vital for complex skills in childhood and is sensitive to environmental factors.
• Targeted interventions are explored to enhance working memory and related executive functions in children.
• Existing working memory training studies often report promising results but lack methodological rigor.

Purpose of the Study:

• To review the methodological quality of process-based working memory training studies in children.
• To analyze the impact of methodological criteria on the internal validity of these studies.
• To discuss limitations and suggest improvements for future research.

Main Methods:

• Systematic review of working memory training literature for children.
• Assessment of adherence to key methodological criteria: control groups (preferably active) and random assignment.
• Analysis of the influence of these criteria on study internal validity.

Main Results:

• Many studies exhibit methodological weaknesses, impacting the reliability of working memory training efficacy claims.
• Inconsistent use of active control groups and random assignment compromises internal validity.
• Motivational factors associated with interventions are often inadequately controlled.

Conclusions:

• The efficacy of current working memory training interventions in children remains uncertain due to methodological limitations.
• Future research must prioritize robust methodologies, including appropriate control conditions and randomization.
• Addressing these limitations is essential for advancing our understanding of working memory development and intervention effectiveness.
