Role of Working Memory Storage and Attention Focus Switching in Children’s Comprehension of Spoken Object Relative Sentences

Table 3

Hierarchical linear regression analysis for predicting OR sentence comprehension using age, working memory storage (WMs), and attention switching accuracy as the predictors (𝑁=44).

Variable	𝛽	Δ𝐹	(df1, df2)	Δ𝑅^2
Step 1
Age	.001	12.86	(1, 42)	.234**
Step 2
Age, WMs	.404	9.84	(1, 41)	.148*
Step 3
Age, WMs,; Attention Switching	.017	11.37	(1, 40)	.137*

Note. Total variance accounted for = 53%. **Significant at 𝛼=.001 (2 tailed) and *significant at 𝛼=.01 (2 tailed).
