This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/Psycholinguistic models of spoken word production differ in how they conceptualize the relationship between lexical, phonological and output representations, making different predictions for the role of production in language acquisition and language processing. This work examines the impact of production on spoken word recognition of newly learned non-words. In Experiment 1, adults were trained on non-words with visual referents; during training, they produced half of the non-words, with the other half being heard-only. Using a visual world paradigm at test, eye tracking results indicated faster recognition of non-words that were produced compared with heard-only during training. In Experiment 2, non-words were correctly pronounced or mispronounced at test. Participants showed a different pattern of recognition for mispronunciation on non-words that were produced compared with heard-only during training. Together these results indicate that production affects the representations of newly learned words.Peer reviewedFinal Accepted Versio

Input-based phonological acquisition
This dissertation contrasts two theories of language acquisition. The first theory (Universal Grammar Hypothesis - UGH), which has been dominant in generative linguistics, argues that acquisition is primarily mediated by innate properties of language provided by UG. The opposing view (General Pattern Learning Hypothesis - GPLH) is that language is acquired according to the patterns in the ambient language or input. These theories are contrasted by examining children's acquisition of coda consonants in CVC words. The UGH was based on the universally preferred codas. These data came from previous research and from frequency analyses of codas in CVC words from 35 languages. Results showed that languages prefer coronal codas and sonorant codas. These cross-linguistic preferences are interpreted as reflecting UG. Predictions of the GPLH were established through an examination of English codas in CVC words from a number of different sources. This examination revealed the frequency of codas in the input, upon which the GPLH was based. In order to determine which hypothesis better predicts children's coda acquisition, data were then collected from previously published research, from CHILDES, and from an experiment designed to test children's productions of English codas. To evaluate the UGH, children's coda productions were analysed to determine whether the preferred codas were coronals or sonorants. Results showed that neither of these codas were favoured. To evaluate the GPLH, analyses determined whether there were significant correlations between children's coda productions and the frequency of codas in English. Results showed that these relationships were significant. The role of the input was further examined in an experiment designed to test children's productions of the identical coda in non-words controlled for phonotactic probabilities. Results showed that phonotactic probabilities played a significant role in accounting for children's productions of the identical coda in different words. The results support an input-based account of phonological acquisition. Thus, language acquisition is best characterised with respect to patterns in the ambient language, where frequently occurring properties of the input serve to organise children's linguistic representations. The research here illustrates the importance of considering the input in children's acquisition of phonological structures

Representations in the Developing Lexicon for Consonants and Vowels
Gradient phonological relationships: Evidence from vowels in French
The dichotomy of contrastive and allophonic phonological relationships has a long-standing tradition in phonology, but there is growing research that points to phonological relationships that fall between contrastive and allophonic. Measures of lexical distinction (minimal pair counts) and predictability of distribution were applied to Laurentian French vowels to quantify three degrees of contrast between pairs: high, mid, and low contrast. According to traditional definitions, both the high and mid contrast pairs are classified as phonologically contrastive, and low contrast pairs as allophonic. As such, a binary view of contrast (contrastive vs. non-contrastive) predicted that high and mid contrast pairs would pattern together on tasks of speech perception, and low contrast pairs would show a different pattern. The gradient view predicted all vowel pairs would fall along a continuum. Thirty-two speakers of Laurentian French participated in two experiments: an AX task and a similarity rating task. The results did not support a strict binary interpretation of contrast, since the high, mid, and low contrast vowel pairs pattern differently across the experiments. Instead, the results support a gradient view of phonological relationships. Â This article is part of the special collection: Marginal Contrasts</a

The role of long-distance phonological processes in spoken word recognition: A preliminary investigation
Previous work has demonstrated that during spoken word recognition, listeners can use a variety of cues to anticipate an upcoming sound before the sound is encountered. However, this vein of research has largely focused on local phenomena that hold between adjacent sounds. In order to fill this gap, we combine the Visual World Paradigm with an Artificial Language Learning methodology to investigate whether knowledge of a long-distance pattern of sibilant harmony can be utilized during spoken word recognition. The hypothesis was that participants trained on sibilant harmony could more quickly identify a target word from among a set of competitors when that target contained a prefix which had undergone regressive sibilant harmony. Participants tended to behave as expected for the subset of items that they saw during training, but the effect did not reach statistical significance and did not extend to novel items. This suggests that participants did not learn the rule of sibilant harmony and may have been memorizing which base went with which alternant. Failure to learn the pattern may have been due to certain aspects of the design, which will be addressed in future iterations of the experiment
Combining and integrating multiple linguistic cues during spoken language comprehension: A focus on semantics and coarticulation
This research examines how adults process and integrate a combination of higher-level semantic cues (i.e., semantic context) which are followed by lower-level acoustic cues (i.e., coarticulatory cues) during online spoken comprehension. Previous studies investigating cue integration (e.g., Martin, 2016) found that listeners can flexibly use and integrate a variety of available cues across linguistic representations. The current pre-registered study used an eye-tracking paradigm and tested a previously unstudied combination of cues. Specifically, how listeners process coarticulation (a lower-level cue) in the presence of preceding semantic information (a higher-level cue). Adult listeners were sensitive to both semantic and coarticulatory cues; moreover, adults’ processing of later acoustic cues varied depending on the earlier semantic context. These results demonstrate that listeners can flexibly use and weigh cues across multiple levels of linguistic representations during language comprehension. Earlier semantic information can be maintained over time and can influence the processing of later lower-level acoustic cues
Developmental change in children’s speech processing of auditory and visual cues: An eyetracking study
This study investigates how children aged two to eight years (N = 129) and adults (N = 29) use auditory and visual speech for word recognition. The goal was to bridge the gap between apparent successes of visual speech processing in young children in visual-looking tasks, with apparent difficulties of speech processing in older children from explicit behavioural measures. Participants were presented with familiar words in audio-visual (AV), audio-only (A-only) or visual-only (V-only) speech modalities, then presented with target and distractor images, and looking to targets was measured. Adults showed high accuracy, with slightly less target-image looking in the V-only modality. Developmentally, looking was above chance for both AV and A-only modalities, but not in the V-only modality until 6 years of age (earlier on /k/-initial words). Flexible use of visual cues for lexical access develops throughout childhood.

Infants track word forms in early word-object associations
A central component of language development is word learning. One characterization of
this process is that language learners discover objects and then look for word forms to
associate with these objects (Mcnamara, 1984; Smith, 2000). Another possibility is that
word forms themselves are also important, such that once learned, hearing a familiar
word form will lead young word learners to look for an object to associate with it
(Juscyzk, 1997). This research investigates the relative weighing of word forms and
objects in early word-object associations using the anticipatory eye-movement paradigm
(AEM; McMurray & Aslin, 2004). Eighteen-month-old infants and adults were taught
novel word-object associations and then tested on ambiguous stimuli that pitted word
forms and objects against each other. Results revealed a change in weighing of these
components across development. For 18-month-old infants, word forms weighed more in
early word-object associative learning, while for adults, objects were more salient. Our
results suggest that infants preferentially use word forms to guide the process of word-object
association.Arts, Faculty ofPsychology, Department ofReviewedFacult
