This dissertation examines native speakers' word recognition of, differentiation between, and social attitudes toward varieties of Arabic. It is a particularly interesting test case because of the Arabic unique regional variation situation and the available literature lacks data on how Arabic speakers perceive different accents, with a particular…

Automaticity in recognizing the words in a text is fundamental to comprehension. If the number of words readers need to stop and decode exceeds their ability to retain their understanding of a narrative's plot or an expository text's description, their comprehension suffers. The conventional intervention for students who lack the automaticity to…

Purpose: Adults recognize words that are acquired during childhood more quickly than words acquired during adulthood. This is known as the Age of Acquisition (AoA) effect. The AoA effect, according to the integrated account, manifests in tasks necessitating greater semantic processing and in tasks with arbitrary input-output mapping. Compound…

During spoken word processing, native (L1) listeners use allophonic variation to predictively rule out word competitors and speed up word recognition. There is some evidence that second language (L2) learners develop an awareness of allophonic distributions in their L2, but whether they use their knowledge to facilitate word recognition online,…

Background: Arabic is recognised as diglossic; one manifestation of diglossia is the co-existence of two varieties of the language used in different social settings: standard (or literary) Arabic (StA) and spoken Arabic (SpA). The study investigated the impact of lexical-phonological distance in Arabic (identical, cognate, unique, which are…

Foreign accents can vary considerably in the degree to which they deviate from the listener's native accent, but little is known about how the relationship between a speaker's accent and a listener's native language phonology mediates adaptation. Using an artificial accent methodology, we addressed this issue by constructing a set of three…

Successful word recognition requires that listeners attend to differences that are phonemic in the language while also remaining flexible to the variation introduced by different voices and accents. Previous work has demonstrated that American-English-learning 19-month-olds are able to balance these demands: although one-off one-feature…

Many studies evidence the flexibility of speech perception in the first language (L1), which allows rapid adaptation to unfamiliar foreign accents. Two influential studies by Bradlow and Bent (2008) and a follow-up study by Baese-Berk et al. (2013) found that increased variability as a function of the number of talkers and accents facilitated the…

The present study investigated the influence of orthographic input on the recognition of second language (L2) spoken words with phonological variants, when first language (L1) and L2 have different orthographic structures. Lexical encoding for intermediate-to-advanced level Mandarin learners of Korean was assessed using masked cross-modal and…

Spoken word recognition depends on variations in fine-grained phonetics as listeners decode speech. However, many models of second language (L2) speech perception focus on units such as isolated syllables, and not on words. In two eye-tracking experiments, we investigated how fine-grained phonetic details (i.e. duration of nasalization on…

Spoken words vary phonetically along a number of dimensions, such as duration, pitch, and vowel quality. Much of this variation is associated with social factors like the dialect, age, or gender of the speaker -- a type of variation termed 'socio-indexical'. Traditional theories of speech perception have seen this socio-indexical variation as a…

The ability to map similar sounding words to different meanings alone is far from enough for successful speech processing. To overcome variability in the speech signal, young learners must also recognize words across surface variations. Previous studies have shown that infants at 14 months are able to use variations in word-internal cues (i.e.,…

Infants struggle to understand familiar words spoken in unfamiliar accents. Here, we examine whether accent exposure facilitates accent-specific adaptation. Two types of pre-exposure were examined: video-based (i.e., listening to pre-recorded stories; Experiment 1) and live interaction (reading books with an experimenter; Experiments 2 and 3).…

To isolate cross-lingual phonological effects during visual-word recognition, Arabic-Hebrew bilinguals who are native speakers of Spoken Arabic (SA) and proficient readers of both Literary Arabic (LA) and Hebrew, were asked to perform a visual lexical-decision task (LDT) in either LA (Experiment 1) or Hebrew (Experiments 2 and 3). The critical…

In conversational speech, it is very common for words' segments to be reduced or deleted. However, previous research has consistently shown that during spoken word recognition, listeners prefer words' canonical pronunciation over their reduced pronunciations (e.g., pretty pronounced [word omitted] vs. [word omitted]), even when the latter are far…
