Can verbal working memory training improve reading?

Area of Science:

• Cognitive Psychology
• Developmental Neuroscience

Background:

• Poor word reading accuracy and verbal working memory are common in children.
• The causal relationship between these two deficits is not fully understood.

Purpose of the Study:

• To investigate the causal relationship between verbal working memory and word reading accuracy.
• To determine if verbal working memory training or reading training can improve deficits in the other area.

Main Methods:

• A case series of four children with deficits in both verbal working memory and word reading accuracy.
• Each child underwent 8 weeks of verbal working memory training and 8 weeks of reading training.

Main Results:

• Verbal working memory training improved verbal working memory in 50% of participants but did not impact reading accuracy.
• Reading training improved word reading accuracy in all participants but did not affect verbal working memory.

Conclusions:

• The findings suggest that the causal links between verbal working memory and reading accuracy are not as direct as previously assumed.
• Interventions targeting one skill may not automatically improve the other, indicating distinct underlying mechanisms.
