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

Phonological 'wildness' in early language development: exploring the role of onomatopoeia

This study uses eye-tracking to single out the role of ‘wild’ onomatopoeia in language development, as described by Rhodes (1994). Wildness–whereby extra-phonetic features are used in order to reproduce non-human sounds–is thought here to facilitate infants’ understanding of onomatopoeic word forms, providing a salient cue for segmentation and understanding in the input. Infants heard onomatopoeic forms produced in familiar and unfamiliar languages, presented in a phonologically ‘wild’ (W) or ‘tame’ (T) manner. W forms in both familiar and unfamiliar languages were hypothesised to elicit longer looking times than T forms in both familiar and unfamiliar languages. Results reflect the role that onomatopoeia play in early language development: wildness was not found to be a factor in infants’ understanding of word forms, while reduplication and production knowledge of specific stimuli generated consistent responses across participants

A faster path between meaning and form? Iconicity facilitates sign recognition and production in British Sign Language

A standard view of language processing holds that lexical forms are arbitrary, and that non-arbitrary relationships between meaning and form such as onomatopoeias are unusual cases with little relevance to language processing in general. Here we capitalize on the greater availability of iconic lexical forms in a signed language (British Sign Language, BSL), to test how iconic relationships between meaning and form affect lexical processing. In three experiments, we found that iconicity in BSL facilitated picture-sign matching, phonological decision, and picture naming. In comprehension the effect of iconicity did not interact with other factors, but in production it was observed only for later-learned signs. These findings suggest that iconicity serves to activate conceptual features related to perception and action during lexical processing. We suggest that the same should be true for iconicity in spoken languages (e.g., onomatopoeias), and discuss the implications this has for general theories of lexical processing

Phonological Iconicity

The arbitrariness of the linguistic sign is a fundamental assumption in modern linguistic theory. In recent years, however, a growing amount of research has investigated the nature of non-arbitrary relations between linguistic sounds and semantics. This review aims at illustrating the amount of findings obtained so far and to organize and evaluate different lines of research dedicated to the issue of phonological iconicity. In particular, we summarize findings on the processing of onomatopoetic expressions, ideophones, and phonaesthemes, relations between syntactic classes and phonology, as well as sound-shape and sound-affect correspondences at the level of phonemic contrasts. Many of these findings have been obtained across a range of different languages suggesting an internal relation between sublexical units and attributes as a potentially universal pattern

The Development of Spontaneous Sound-Shape Matching in Monolingual and Bilingual Infants During the First Year

Online First November 17, 2016Supplemental materials: http://dx.doi.org/10.1037/dev0000237.suppRecently it has been proposed that sensitivity to nonarbitrary relationships between speech sounds and objects potentially bootstraps lexical acquisition. However, it is currently unclear whether preverbal infants (e.g., before 6 months of age) with different linguistic profiles are sensitive to such nonarbitrary relationships. Here, the authors assessed 4- and 12-month-old Basque monolingual and Spanish-Basque bilingual infants’ sensitivity to cross-modal correspondences between sound symbolic nonwords without syllable repetition (buba, kike) and drawings of rounded and angular shapes. The findings demonstrate that sensitivity to sound-shape correspondences emerge by 12 months of age in both monolinguals and bilinguals. This finding suggests that spontaneous sound-shape matching is likely to be the product of language learning and development and may not be readily available prior to the onset of word learning

The Two Meanings of Sound Symbolism

This article deals with sound symbolism and the ways to interpret sound symbolic phenomena. Sound symbolism appears to be a universal phenomenon but linguists tend to neglect it or offer heterogeneous approaches and definitions. This paper is concerned with the role of motivation, as assumed in cases like cuckoo, and the question whether some sound symbolic effects might be the result of acquired statistical knowledge about the language system. The author argues that several aspects of sound symbolism such as natural/iconic or habitual relationships between sound and (facets of) referents interact but should be considered separately to gain a more realistic insight into the working of sound symbolism

The building blocks of sound symbolism

Languages contain thousands of words each and are made up by a seemingly endless collection of sound combinations. Yet a subsection of these show clear signs of corresponding word shapes for the same meanings which is generally known as vocal iconicity and sound symbolism. This dissertation explores the boundaries of sound symbolism in the lexicon from typological, functional and evolutionary perspectives in an attempt to provide a deeper understanding of the role sound symbolism plays in human language. In order to achieve this, the subject in question was triangulated by investigating different methodologies which included lexical data from a large number of language families, experiment participants and robust statistical tests.Study I investigates basic vocabulary items in a large number of language families in order to establish the extent of sound symbolic items in the core of the lexicon, as well as how the sound-meaning associations are mapped and interconnected. This study shows that by expanding the lexical dataset compared to previous studies and completely controlling for genetic bias, a larger number of sound-meaning associations can be established. In addition, by placing focus on the phonetic and semantic features of sounds and meanings, two new types of sounds symbolism could be established, along with 20 semantically and phonetically superordinate concepts which could be linked to the semantic development of the lexicon.Study II explores how sound symbolic associations emerge in arbitrary words through sequential transmission over language users. This study demonstrates that transmission of signals is sufficient for iconic effects to emerge and does not require interactional communication. Furthermore, it also shows that more semantically marked meanings produce stronger effects and that iconicity in the size and shape domains seems to be dictated by similarities between the internal semantic relationships of each oppositional word pair and its respective associated sounds.Studies III and IV use color words to investigate differences and similarities between low-level cross-modal associations and sound symbolism in lexemes. Study III explores the driving factors of cross-modal associations between colors and sounds by experimentally testing implicit preferences between several different acoustic and visual parameters. The most crucial finding was that neither specific hues nor specific vowels produced any notable effects and it is therefore possible that previously reported associations between vowels and colors are actually dependent on underlying visual and acoustic parameters.Study IV investigates sound symbolic associations in words for colors in a large number of language families by correlating acoustically described segments with luminance and saturation values obtained from cross-linguistic color-naming data. In accordance with Study III, this study showed that luminance produced the strongest results and was primarily associated with vowels, while saturation was primarily associated with consonants. This could then be linked to cross-linguistic lexicalization order of color words.To summarize, this dissertation shows the importance of studying the underlying parameters of sound symbolism semantically and phonetically in both language users and cross-linguistic language data. In addition, it also shows the applicability of non-arbitrary sound-meaning associations for gaining a deeper understanding of how linguistic categories have developed evolutionarily and historically
