Theme-experiencer verbs, like 'amuse', for which the experiencer is the object of an active clause (e.g., 'the joke amused the host'), are distinguished theoretically from action verbs, like 'clean', and experiencer-theme verbs, like 'cherish', for which the experiencer is the subject of an active clause. Three experiments are reported in which readers' comprehension of these verbs was examined using a meaning-classification paradigm. Active themeexperiencer sentences were read for longer than actives containing the other verb types. By contrast, passive theme-experiencer sentences resulted in fewer errors and shorter reading times than passives containing experiencertheme verbs, and in terms of errors, theme-experiencer passives resembled adjectival structures. Findings were consistent with a previous account by Belletti and Rizzi of the syntactic differences between verb types, although a semantic explanation was not discounted. A correspondence between the language systems responsible for comprehension and production was implied, given the similarity between these results and those of a 1994 study by Ferreira.
