Languages (spoken and signed) are iconic in addition to being arbitrary. What is iconicity and why is it there?
Iconicity describe those cases in which the linguistic form evokes some properties of referent, as it is the case in onomatopoeic words (e.g., 鈥渂oom鈥�, 鈥渜uack鈥�), or in hand gestures that evoke properties of shape of objects or manner of actions. We have put forward the proposal that iconicity (i.e., presence of transparent relationships between linguistic form and properties of referents may have had a critical role in language evolution. It also has a critical role in language learning and language processing.
We argue that in language evolution, iconicity has been pivotal to the development of language as a displaced communicative system (i.e., the possibility to use language to talk about things and events which are not present in the immediate environment). In language development iconicity would be critical to establishing a link between linguistic forms and referents in the world and in language processing it could support efficient comprehension and production.
Much of the work that has led to this proposal comes from studies of Sign Language learning and processing, carried out as part of our DCAL projects).
Currently, we are especially interested in how multimodal (i.e., comprising the speech, but also the prosody and gestures) communication in spoken languages exploit iconicity. In one project (funded by the ESRC) we ask whether caregivers use iconicity to help their children learn new labels.听In a first study in British Sign Language (BSL) we have compared the language used by caregivers when describing sets of objects when the objects where present to when they were absent. We found that caregivers modify their language making it more iconic when objects are not present. Our interpretation is that these changes help building a mental image of referents when they are absent and therefore support learning. Currently,听we are investigating the听multimodal听language (including prosody and gestures) of English speaking caregivers of children aged 2-3 to see whether they use iconicity (onomatopoeias, prosodic modulation and gestures) especially when objects are absent and especially when the objects are unknown to the child听 and if such iconicity supports learning of new labels and new concepts.
