This research examines focusing preferences for referents of pronouns following two types of verbs. The first type, transfer verbs (e.g., pass, bring), is a special case of the second type, experiential verbs (e.g., scare, trust). The frequency data from these corpus studies is compared with previous experimental research. Both studies confirm that with thematic roles (Goal and Source; Stimulus and Experiencer), continuations with pronouns are predictable. In experiential verbs, this is dependent on verb type (Stimulus-Experiencer vs. Experiencer-Stimulus), so there is an interaction between thematic roles and grammatical functions, which is consistent with Arnold (2001). For transfer verbs, there was an overall Goal bias. Guarantee of transfer (a distinction made by Hartshorne & Snedeker) did not influence the predictability of the continuation based on thematic roles. The object bias percentages per verb found by Hartshorne & Snedeker (in press) show a moderate correlation with the percentages from this study. The fact that this correlation is not higher could be caused by the difference in structure of the studies: a corpus study produces noisier data than a controlled experiment.
