Mental State Verbs

This study investigated children ‘s understanding (3-, 6, 9-, and 12-year-olds) of the different levels of meaning of the cognitive verb know as defined by the Hall, Scholnick, and Hughes (1987) abstractness andconceptual dificulty hierarchy. Weness andconceptual dificulty hierarchy. We found that cognitive verb knowledge increased with development and that certain low levels of meaning were mastered before certain high levels of meaning irrespective of the medium of presentation: videotaped “skits” and audiotaped “stories. ’ However, children developed an understanding of low levels of meaning at a more rapid rate than high levels of meaning. Ibis resulted in a more differentiated and hierarchical cognitive verb knowledge in older children. Finally, we found that the audiotaped stories were more dificult than the videotaped skits, and that both tasks were significantly correlated with a standardized vocabulary measure for all ages except the 3-year-olds. The implications of this study and others for a model of the cognitive verb lexicon
