Spanish lower and upper bounded change of state verbs: focusing on transitive experiencer object verbs

Transitive causative change of state (TCoS) verbs elicit scalar readings, distinguishing them between: upper-bounded verbs (e.g., dry), denoting a culminating change of state, and lower-bounded verbs (e.g., wrinkle), denoting a change from a zero to a non-zero value (or from one value to another) regarding the property described by the semantic core of the verb. In their eventive reading, transitive experiencer object (TEO) verbs (e.g., calm down, delight) also denote causative eventualities able to yield scalar inferences. This study investigates whether TEO verbs are also associated with a minimum or maximum standard degree, proposing a similar subdivision of TEO verbs into lower-bounded items (delight) and upper-bounded items (calm down). In a forced-choice selection experiment we tested the impact of the standard degree (bound) of the semantic core of Spanish TEO verbs on the availability of lower-bounded or upper-bounded readings comparing them to TCoS verbs. Results revealed that the factor bound was significant to the extent that both lower-bounded TEO and TCoS predicates yielded the response compatible with a lower-bounded reading significantly more often than predicates that possess a maximum degree, supporting the distinction between lower and upper bounded items. Further, a significant effect of verb type was also observed, differentiating a change of state on the mental (TEO) versus the physical (TCoS) levels.
