Abstract

Meanings communicated with depictions constitute an integral part of how speakers and signers actually use language (Clark, 2016). Recent studies have argued that, in sign languages, depicting strategy like constructed action (CA), in which a signer enacts the referent, is used for referential purposes in narratives. Here, we tested the referential function of CA in a more controlled experimental setting and outside narrative context. Given the iconic properties of CA we hypothesized that this strategy could be used for efficient information transmission. Thus, we asked if use of CA increased with the increase in the information required to be communicated. Twenty-three deaf signers of LIS described unconnected images, which varied in the amount of information represented, to another player in a director–matcher game. Results revealed that participants used CA to communicate core information about the images and also increased the use of CA as images became informatively denser. The findings show that iconic features of CA can be used for referential function in addition to its depictive function outside narrative context and to achieve communicative efficiency.

Abstract

This study investigates whether there is a universal tendency for content
interrogative words (wh-­words) within a language to sound similar in order to facilitate
pragmatic inference in conversation. Gaps between turns in conversation are very
short, meaning that listeners must begin planning their turn as soon as possible.
While previous research has shown that paralinguistic features such as prosody and
eye gaze provide cues to the pragmatic function of upcoming turns, we hypothesise
that a systematic phonetic cue that marks interrogative words would also help early
recognition of questions (allowing early preparation of answers), for instance wh-­
words sounding similar within a language. We analyzed 226 languages from 66
different language families by means of permutation tests. We found that initial
segments of wh-­words were more similar within a language than between languages,
also when controlling for language family, geographic area (stratified permutation)
and analyzability (compound phrases excluded). Random samples tests revealed that
initial segments of wh-­words were more similar than initial segments of randomly
selected word sets and conceptually related word sets (e.g., body parts, actions,
pronouns). Finally, we hypothesized that this cue would be more useful at the
beginning of a turn, so the similarity of the initial segment of wh-­words should be
greater in languages that place them at the beginning of a clause. We gathered
typological data on 110 languages, and found the predicted trend, although statistical
significance was not attained. While there may be several mechanisms that bring
about this pattern (e.g., common derivation), we suggest that the ultimate explanation
of the similarity of interrogative words is to facilitate early speech-­act recognition.
Importantly, this hypothesis can be tested empirically, and the current results provide
a sound basis for future experimental tests.

Abstract

Turn-taking in conversation is a cognitively demanding process that proceeds rapidly due to interlocutors utilizing a range of cues
to aid prediction. In the present study we set out to test recent claims that content question words (also called wh-words) sound similar within languages as an adaptation to help listeners predict
that a question is about to be asked. We test whether upcoming questions can be predicted based on the first phoneme of a turn and the prior context. We analyze the Switchboard corpus of English
by means of a decision tree to test whether /w/ and /h/ are good statistical cues of upcoming questions in conversation. Based on the results, we perform a controlled experiment to test whether
people really use these cues to recognize questions. In both studies
we show that both the initial phoneme and the sequential context help predict questions. This contributes converging evidence that elements of languages adapt to pragmatic pressures applied during
conversation.
