Material and conditions Clause Samples

Material and conditions. Material was made of videos recorded by a native speaker of American English following model videos recorded by one of the authors. All videos were made of sentences with two parts. The first part always contained a gestural verb, matching with the content of the statement in that part of the sentence. The second part either contained another gesture, or an elided VP whose antecedent was the gestural verb. This second gesture, whether explicit or elided, could then either match or mismatch with the statement in that second part of the sentence. There were therefore in principle 2 (gesture or ellipsis) times 2 (match or mismatch) possible conditions. In the target conditions, the match/mismatch manipulation was used to test the effect of person marking, either under ellipsis (Ellipsis-Mismatch condition) or explicitly (Gesture-Mismatch condition). For a given gesture, when this was possible (with SHOOT and PUNCH) the model sought to vary only the target locus of the movement, and thus his eye gaze remained towards the camera; this was not possible in the SEND-KISSES condition because in the third person condition the model's face had to be turned towards the third person locus. We obtained the set of conditions described in the table in (34). The Ellipsis-Match was absent from the paradigm because, given the general set up, this would have required the introduction of a second third person locus – a possibility that has not been verified yet. The actual examples are transcribed in (36)-(38), with relevant gestures given in (35).
