In an effort to understand cognitive foundations of oral language comprehension (i.e., listening comprehension), we examined how inhibitory control, theory of mind, and comprehension monitoring are uniquely related to listening comprehension over and above vocabulary and age. A total of 156 children in kindergarten and first grade from high-poverty schools participated in the study. Using structural equation modeling, results showed that all three cognitive skills (inhibitory control, theory of mind, and comprehension monitoring) were positively related to listening comprehension after accounting for vocabulary and age. In addition, inhibitory control had a direct relation to listening comprehension, not indirectly via theory of mind. Results are discussed in light of cognitive component skills for listening comprehension.
