Universal meaning extensions of perception verbs are grounded in interaction

Acknowledgements
We wish to thank our collaborators (listed in Figure 1), who were critical in collating the database upon which we rely in this paper (see San Roque et al. 2015). This collaboration was made possible through the generous support of Stephen Levinson. We also gratefully acknowledge the efforts of the people from the language communities who were recorded, and those who worked with the named investigators on recording, transcription and analysis of data. Two anonymous reviewers and Bernard Wälchli gave invaluable advice that greatly improved the paper, as did John Newman. Thanks also to Carolyn O’Meara. This study was funded by: Max Planck Institute for Psycholinguistics (Language and Cognition Department); Ammodo KNAW Award; Netherlands Organisation for Scientific Research/NWO (VICI 277-70-011 and VENI 275-89-024).
Abbreviations and conventions:
Annotations following examples show the language (identified by the first three letters), the number of the example in the database (from San Roque et al. 2015), and the initials of the contributing researcher(s). In some longer examples, the duration of pauses (in seconds) are noted in parentheses. Overlapped elements of speech are indicated using a square bracket in the original language line to show the point where overlap between speakers commences. Notation concerning participants’ actions (e.g., pointing) are enclosed in double parentheses. In the interests of space we give an interlinear gloss only for lines that include a perception verb. In translation lines, an English approximation of the transfield association of the perception verb is shown in bold. This is not intended to exclude the possibility of a co-present literal perception meaning. For intrafield associations, extended meanings are shown in square brackets.
Interlinear gloss abbreviations are:
1
first person
2
second person
3
third person
