Analyses of Covariance: Group (ADHD vs. Control) × Sentence Structure × Verb Type

Interaction	Analysis
3-way
Group × Sentence Structure × Verb Type	F(1, 283) = 0.44, p > .10, η² = .002
2-way
Sentence Structure × Verb Type	F(1, 283) = 9.27, p < .05, η² = .032
Sentence Structure × Group	F(1, 283) = 4.30, p < .05, η² = .015
Verb Type × Group	F(1, 283) = 2.84, p > .05, η² = .010
Main effects
Sentence structure	F(1, 283) = 44.68, p < .05, η² = .136
Verb type	F(1, 283) = 3.00, p > .05, η² = .010
Group	F(1, 283) = 5.53, p < .05, η² = .019

Note. ADHD = attention-deficity/hyperactivity disorder.
