Morphological Representations In Lexical Processing
… representations involved in auditory lexical processing. Previous work in theoretical morphology, spoken word recognition, and morphological processing are considered together in generating hypotheses. Chapter 2 provides theoretical and methodological background. Theoretical …

L2 Phonetic Detail in L1 Lexical Processing
… unfamiliar accents cause delayed and disrupted lexical access during spoken word recognition, but that these effects are gradient and attenuated by factors including the degree of mismatch and listener experience (Andruski et al., 1994; Bent & Bradlow, 2003; Bradlow & Bent, 2008; Floccia et al., …

Non-native perception, production, and lexical processing of tone
… first language, namely the function of pitch for lexical distinctions (‘L1 tonal status’) and the shapes of native tonal and intonational contrasts (‘tone type’), as well as extralinguistic factors, namely musical experience, working memory, and pitch perception aptitude. In doing so, I aim to …

Semantically Based Lexical Processing Yields Unique Topographic Contributions to the Speech Bereitschaftspotential
… that articulatory complexity and semantic processing each contribute to observed variations in the speech BP topography. Eighteen healthy volunteers performed 3 speech tasks, designed to distinguish semantic and articulatory contributions to the BP topography. The findings suggested that …

THE ROLE OF PHONOLOGY AND SEMANTICS IN THE LEXICAL PROCESSING OF ASL CORE LEXICAL ITEMS AND CLASSIFIER CONSTRUCTIONS
This MA thesis explores lexical processing in American Sign Language (ASL). Although a model of lexical processing exists for spoken languages, the research on lexical processing, storage, and organization in signed languages is not very extensive and has been focused on the core lexicon. The …

Sublexical, lexical and phonological short-term memory processes: Evaluating models of speech perception and short-term memory
… to traditional models which assume that sublexical processing necessarily precedes lexical processing (e.g., McClelland & Elman, 1986; Norris, 1994), several studies have demonstrated that patients may perform better on lexical than sublexical speech perception tasks (e.g., Miceli, Gainotti, …

The return-sweep in reading.
… characteristics, this thesis examined how lexical processing is influenced by return-sweep execution in both adults and children. Following a review of the existing eye movement literature in chapter 1, chapter 2 examined the basic characteristics of return-sweep saccades. The reported data …

Mechanisms of Spoken Word Recognition and Memory Encoding Studied through Competitor Priming
… (e.g. TRACE) propose direct competition between lexical units such that inhibition of irrelevant candidates leads to selection of critical words, while predictive-selection accounts (e.g. Predictive Coding) suggest that computations of prediction error by comparing heard and predicted speech …

Semantic ambiguity in the lexical access of verbs: how data from monolinguals and bilinguals inform a general model of the mental lexicon
… study of Spanish verbs and an online language processing study investigating whether bilingual lexical processing is nonselective (both languages are activated) when only one language is required for use. To study bilingual lexical processing, researchers have relied upon words of shared …

Credit Rating and Assignment of Naics Codes Using Lsi Method
… assignment of industry codes using LSI (lexical processing) by increasing the algorithm efficiency (both computationally and in term of input requirements), then quantify the lender's risk as "distance to default" (higher distance to default indicates default is less likely to occur), …

Measuring children’s sensitivity to phonological detail using eye tracking and pupillometry
Infants' lexical processing is modulated by featural manipulations made to words, suggesting that early lexical representations are sufficiently specified to establish a match with the corresponding label. However, the precise degree of detail in early words requires further investigation due to …

Pictures, Words, And Synonymy: Representations And Processes
… represented with the hypothesis that synonymy is lexically represented. They also stress the importance of task focal information in the interpretation of experimental results. Current mental models appear to operate with the implicit assumption that synonymy is represented semantically. The …

The Phonetic Specificity of British English-Learning Infants’ Word Form Recognition in Their First Year of Life
… in speech perception: a consonant bias for lexical processing and a vowel bias for syntactic/prosodic processing (Nespor et al., 2003). Research in adults has consistently demonstrated that consonants have a privileged role in various lexical-level experiments across most languages. However, …

The Link Between Fixation Location and Attention During Reading: Its Extent and Nature
… dissociations necessarily implicate parallel lexical processing, or whether they can be accommodated for within a serial-sequential framework is explored in a series of experiments. Experiment 1 tested whether parallel lexical processing is, at the very least, psychologically plausible. Two …

SENSITIVITY TO VOWEL, CONSONANT AND TONE VARIATION IN EARLY CHILDHOOD: EVIDENCE FROM 6-YEAR-OLD MANDARIN MONOLINGUALS AND ENGLISH-MANDARIN BILINGUALS
… is known about how tones are integrated into lexical representations in comparison to more typically studied vowels and consonants. Most of the previous work investigating lexical processing in tone language learners has focused on infants and toddlers. A key finding from this research is that …

Cognitive Processes in Second Language Reading (Orthography, Cognition, Bilingualism)
… (L1) orthographic structures on cognitive processing in second language (L2) reading. More specifically, two aspects of L1 orthographic effects were examined: (a) the effects of the basic unit of representation on acoustic coding strategies, and (b) the effects of representational …

A MEG investigation of lexical access in aphasia
… are thought to arise from impaired phonological processing, semantic representations, or both. The present study examined spreading lexical activation in people with aphasia by implementing thorough clinical evaluation, a series of listening tasks, and a time sensitive means of tracking cortical …

Enhancement of verb retrieval: Neuromodulation, repetition priming, and aphasia rehabilitation
… repetition priming reflects changes in implicit processing of stimuli (at the level of lexical retrieval), and explicit episodic retrieval of the prior occurrence of the stimuli. In patients with aphasia, the data indicates that the observation of item-specific improvement after treatment depend …

Magnetoencephalographic investigations of morphological identity and irregularity
… is one in which the mental lexicon consists of lexical roots (sound -meaning pairs that are arbitrary in the Saussurian sense, such as CAT: 'feline'<->/kaet/) and functional morphemes (affixes such as the plural marker -s, that carry purely grammatical information). Complex words are assembled …

Attentional Orientation and Vocabulary Size
… of a word is both an indicator of effective lexical processing and an opportunity to learn new words. Beginning in infancy, faster attentional orientation during recognition and disambiguation is associated with superior vocabulary ability (Bion et al., 2013; Fernald et al., 2006). Yet, …
