Subclaims¶

q3 i3 WMPT accuracy showed large positive correlations with Word Reading (r = .532), Numerical Operations (r = .507) and Composite Score (r = .555), and a moderate correlation with Spelling (r = .359). → Freeman 2017

Evidence¶

Freeman 2017¶

Freeman, Emily E.; Karayanidis, Frini; Chalmers, Kerry A. (2017). Metacognitive monitoring of working memory performance and its relationship to academic achievement in Grade 4 children. Learning and Individual Differences, Vol. 57. http://dx.doi.org/10.1016/j.lindif.2017.06.003

Pearson correlations in the Grade 4 sample (n = 73) linked WMPT accuracy to all WIAT-II outcomes; "Higher WMPT accuracy scores were associated with higher scores in academic achievement", consistent with prior working-memory–achievement findings.

"Pearson correlations conducted to examine the relationship between accuracy on the WMPT and performance on the WIAT-II revealed large positive correlations between WMPT accuracy and Word Reading, r = .532, p < .001, Numerical Operations, r = .507, p < .001, and the Composite Score, r = .555, p < .001, with a moderate positive correlation found for Spelling, r = .359, p = .002."

Related Claims¶

• Confidence on the WMPT predicts numeracy but not reading or spelling — related
• WMPT accuracy, confidence, Bias Index and Absolute Accuracy Index all change significantly with task difficulty — related
• Better calibration (lower Absolute Accuracy Index) is associated with higher Word Reading and Composite achievement scores — related
• Grade 4 children can metacognitively monitor their working memory performance, tending to be over-confident as task difficulty increases — related
