Not this, but that.' Exploring disambiguation in the context of multilingual word learning
|

Abstract:
Growing up and living with more than one language modulates new language learning in a variety of ways. Similarities and differences to monolinguals with regards to languages learning in all its aspects were found. These range from phonology to pragmatics. However, non-linguistic domains, such as cognition, can also be affected by the multilingual experience. The acquisition of words is an indispensable step in learning a language, be that one’s first or subsequent languages. To learn a word, its word form must be correctly mapped onto its meaning and then remembered. One ‘strategy’ children and adults implicitly employ to map a new label to a new item or concept is referred to as disambiguation. This mental process is analogous to the common process-of-elimination and based on the Disjunctive Syllogism. The idea is that a new label refers to a novel object in the presence of familiar items creating the support for one-to-one mappings between a word and its referent. Attaching a new label to a new label-unknown object rather than a familiar label-known object expedites vocabulary growth, especially in children. Although this mental process can be found in adults too, it was predominantly studied in the context of word learning in children, and more recently multilingual children. The interest in researching disambiguation in multilingual contexts arose as researchers began to wonder if people, who grew up and were exposed to more than one language, would exhibit the so-called disambiguation effect at all given that they know multiple labels for the same objects. The formulation of many-to-one mappings stands in opposition to one-to-one mappings mentioned above. However, does this mean that multilingual children and adults never disambiguate? The answer to this question cannot be binary, considering the myriad of direct and indirect effects multilingualism has on word learning. In this thesis, I explore the use of disambiguation in various multilingual contexts: 1. Disambiguation studies on children are usually conducted under the scope of word learning, which consists of mapping and retention of words; however, only very few studies explicitly explore the relationship between the mapping of a new word and the ability to retain it. In this first study, I explored whether and how monolingual and multilingual children’s use of disambiguation as a fast mapping constraint boosted their ability to retain this new mapping within the same experiment. For this, I designed and adapted a looking-while-listening eye-tracking paradigm to allow for data collection within a young population (aged 18 to 30 months old). I found that children from monolingual and multilingual backgrounds are able to use disambiguation as mapping strategy; however, they differ with regards to how disambiguation modulated their ability to retain the new word. Whilst the use of disambiguation positively affected monolingual children’s retention performance, children from multilingual backgrounds did not display this boosting effect. Thus, it can be said that disambiguation starts out as default mapping strategy that in some, but not other, cases develops into a more consolidated learning/retention strategy. 2. In a second study, I examined whether disambiguation as a mapping strategy is prevalent in multilingual adults and how their multilingual experience may modulate the processing speed of this process-of-elimination. Multilingualism does affect a person’s learning not only directly but also indirectly. An accumulating amount of research is currently being conducted on the mutual effects of multilingualism and executive functioning with findings addressing cognitive domains such as working memory and cognitive control. As these findings allude to differences in cognitive processing, any task requiring the contribution of these skills, such as the one in this study, one must control for these variations. In this study, I explored the individual contributions of multilingualism and executive functioning to a fast mapping and retention task. Language experience variables strongly modulated the accuracy and processing times of disambiguation and retention conditions, whereby speed-accuracy trade-offs were found. Furthermore, working memory and cognitive control impacted the accuracy and reaction times. Those with better scores on the working memory task also performed faster. Results highlight the requirement for regarding multilingualism as a multivariate spectrum in future research rather than in dichotomous categories. 3. In a third study, I extended the context of disambiguation by not only examining its use on mappings between words and objects but also on mappings between factual information and objects. Factual information about items in this study are, for instance, “this is the one I keep in the living room”. Studies with young children have shown their tendency to transfer the use of disambiguation onto other domains of language learning, such as assigning new factual information to an unfamiliar object rather than a familiar name-known object. However, it is self-evident that adults may not show this transfer of disambiguation due to their ability to draw from other forms of knowledge, such as their cognitive, semantic, and pragmatic abilities, and life experience in general. In this study, I examined how multilinguals adults’ linguistic experience impacts on the use of disambiguation in factual contexts by looking at eye-gaze data. Furthermore, I probed participants’ underlying decision-making processes by questioning their choices after specific trials. The results showed that adults do not extend disambiguation to contexts other than labels, but that language background did modulate those instances in which disambiguation took place based on contrast. In conclusion, it can be said that disambiguation is a sound strategy for making fast decisions about labels and how they attach to meaning. However, the investigations in this thesis also show that the context in which disambiguation is to be used is paramount to its success or someone’s implicit decision to rely upon it. Lastly, this thesis and its findings contribute to the modern view that multilingualism is a continuum and should be researched and regarded from a holistic angle.
