Working memory, strategy knowledge, and strategy instruction in children with reading disabilities

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Educational Psychology

Background:

• Working memory (WM) is crucial for cognitive tasks, including reading.
• Children with reading disabilities (RD) often exhibit WM deficits.
• Understanding the impact of strategy knowledge and training on WM in RD is vital for targeted interventions.

Purpose of the Study:

• To investigate how strategy knowledge and strategy training affect WM performance in children with and without RD.
• To examine the relationship between strategy stability, cued performance, and WM capacity.
• To determine if WM capacity or strategy-related factors best predict reading comprehension.

Main Methods:

• Two experiments were conducted with children aged 10-11, including groups with and without RD.
• Experiment 1 assessed WM performance under initial, cued, and maintenance conditions, analyzing strategy knowledge.
• Experiment 2 involved random assignment to strategy instruction or control groups to evaluate training effects.

Main Results:

• WM performance improved for both groups under cued conditions, but children with RD consistently performed worse.
• WM capacity measures were stronger predictors of reading comprehension than strategy stability or processing efficiency.
• Strategy training led to significant WM improvements, yet residual differences between reading groups persisted.

Conclusions:

• Stable strategy choices, cued performance, and strategy instruction positively impact WM in children with RD.
• Despite improvements, overall WM performance in children with RD is limited by underlying capacity constraints.
• Interventions should consider both strategy-based approaches and the fundamental limitations in WM capacity for children with RD.
