xsd:string This frame has similarities to Experiencer_subject, but here the verbs are more 'active' in meaning. (For example, they often occur in negative imperatives, e.g. "Don't worry!''). They also differ from Experiencer_subject verbs in that they occur with Topic expressions and can be used in the present progressive: Pat is still worrying about the exam. *Pat is fearing the exam. This frame can be thought of as a blend of a basic emotion frame with Cogitation.
