Children and adults' understanding and use of sound-symbolism in novel words

Sound-symbolism is the inherent link between the sound of a word and its meaning. The aim of this thesis is to gain an insight into the nature of sound-symbolism. There are five empirical chapters, each of which aims to uncover children and adults’ understanding of sound-symbolic words. Chapter 1 is a literature review of sound-symbolism. Chapter 2 is a cross-linguistic developmental study looking at the acquisition of sound-symbolism. Chapter 3 looks at childrens use of sound-symbolism in a verb-learning task. Chapter 4 looks at childrens use of sound-symbolism when learning and memorising novel verbs. Chapter 5 consists of two experiments looking at what exact part of a word is sound-symbolic. This study compared different types of consonants and vowels, across a number of domains in an attempt to gain an understanding of the nature of sound-symbolism. Chapter 6 looks at the potential mechanisms by which sound-symbolism is understood. This study is a replication of previous research, which found that sound-symbolic sensitivity is increased when the word is said and not just heard. There are therefore a total of five empirical chapters each of which attempts to look at the nature of sound-symbolic meaning from a slightly different angle

Sound symbolism facilitates long-term retention of the semantic representation of novel verbs in three-year-olds

Previous research has shown that sound symbolism facilitates action label learning when the test trial used to assess learning immediately followed the training trial in which the (novel) verb was taught. The current study investigated whether sound symbolism benefits verb learning in the long term. Forty-nine children were taught either sound-symbolically matching or mismatching pairs made up of a novel verb and an action video. The following day, the children were asked whether a verb can be used for a scene shown in a video. They were tested with four videos for each word they had been taught. The four videos differed as to whether they contained the same or different actions and actors as in the training video: (1) same-action, same-actor; (2) same-action, different-actor; (3) different-action, same-actor; and (4) different-action, different-actor. The results showed that sound symbolism significantly improved the childrens’ ability to encode the semantic representation of the novel verb and correctly generalise it to a new event the following day. A control experiment ruled out the possibility that children were generalising to the “same-action, different-actor” video because they did not recognize the actor change due to the memory decay. Nineteen children were presented with the stimulus videos that had also been shown to children in the sound symbolic match condition in Experiment 1, but this time the videos were not labeled. In the test session the following day, the experimenter tested the children’s recognition memory for the videos. The results indicated that the children could detect the actor change from the original training video a day later. The results of the main experiment and the control experiment support the idea that a motivated (iconic) link between form and meaning facilitates the symbolic development in children. The current study, along with recent related studies, provided further evidence for an iconic advantage in symbol development in the domain of verb learning. A motivated form-meaning relationship can help children learn new words and store them long term in the mental lexicon

Sound Symbolism Facilitates Word Learning in 14-Month-Olds

Sound symbolism, or the nonarbitrary link between linguistic sound and meaning, has often been discussed in connection with language evolution, where the oral imitation of external events links phonetic forms with their referents (e.g., Ramachandran & Hubbard, 2001). In this research, we explore whether sound symbolism may also facilitate synchronic language learning in human infants. Sound symbolism may be a useful cue particularly at the earliest developmental stages of word learning, because it potentially provides a way of bootstrapping word meaning from perceptual information. Using an associative word learning paradigm, we demonstrated that 14-month-old infants could detect Köhler-type (1947) shape-sound symbolism, and could use this sensitivity in their effort to establish a wordreferent association

Cross-linguistically shared and language-specific sound symbolism in novel words elicited by locomotion videos in Japanese and English

This paper demonstrates a new quantitative approach to examine cross-linguistically shared and language-specific sound symbolism in languages. Unlike most previous studies taking a hypothesis-testing approach, we employed a data mining approach to uncover unknown sound-symbolic correspondences in the domain of locomotion, without limiting ourselves to pre-determined sound-meaning correspondences. In the experiment, we presented 70 locomotion videos to Japanese and English speakers and asked them to create a sound symbolically matching word for each action. Participants also rated each action on five meaning variables. Multivariate analyses revealed cross-linguistically shared and language-specific sound-meaning correspondences within a single semantic domain. The present research also established that a substantial number of sound-symbolic links emerge from conventionalized form-meaning mappings in the native languages of the speakers
