Visual Perception In Hearing Sign Language Users, Jessica M. Lammert Jul 2021

Visual Perception In Hearing Sign Language Users, Jessica M. Lammert

Electronic Thesis and Dissertation Repository

Deaf signers exhibit superior visual perception compared to hearing controls in several domains, including the perception of faces and peripheral motion. These visual enhancements are thought to compensate for an absence of auditory input. However, it is also possible that they reflect experience using a visual-manual language, where signers must process complex moving hand signs and facial cues simultaneously. Thus, the current study sought to isolate the effects of sign language experience by examining how visual perception is altered as a function of American Sign Language (ASL) proficiency in hearing individuals. Hearing signers completed an online test of ASL proficiency …


The Effects Of Linguistic Labels On Object Categorization And Perception, Xuan Pan Apr 2019

The Effects Of Linguistic Labels On Object Categorization And Perception, Xuan Pan

Electronic Thesis and Dissertation Repository

The linguistic relativity hypothesis (Whorf, 1956) claims that speakers of different languages perceive and conceptualize the world differently. Language-thought interaction is likely to be more complex in bilinguals because they have two languages that could influence their cognitive and perceptual processes.Lupyan’s (2012) Label-feedback Hypothesis proposes a mechanism underpinning language-thought interactions, arguingthat linguistic labels affect our conceptual and perceptual representations through top-down feedback.This thesis tested the Label-feedback Hypothesis by capitalizing on an interesting feature of Chinese. In English, most nouns do not provide linguistic clues to their categories (an exception issunflower), whereas in Chinese, some nouns provide explicit category …


Enhanced Explicit Vocabulary Learning Compared To Implicit Grammar Learning In Adults, Leah Brainin, Marc Joanisse Mar 2019

Enhanced Explicit Vocabulary Learning Compared To Implicit Grammar Learning In Adults, Leah Brainin, Marc Joanisse

Western Research Forum

Compared to young children, the language learning process is much more difficult and less successful in adulthood. Little is known about how non-linguistic cognitive processes contribute to these age-dependent differences. We argue that language learning involves both explicit declarative memory processes to learn vocabulary and implicit procedural memory processes to learn grammatical patterns. In this preliminary study, we aimed to quantify the relative contribution of declarative versus procedural learning in adults via an artificial language learning task. Participants ages 18 to 29 heard novel singular and plural words associated with images of common objects. The grammar of the language consisted …


Conceptual Representation In Bilinguals: A Feature-Based Approach, Eriko Matsuki Dec 2018

Conceptual Representation In Bilinguals: A Feature-Based Approach, Eriko Matsuki

Electronic Thesis and Dissertation Repository

A challenge for bilinguals is that translation equivalent words often do not convey exactly the same conceptual information. A bilingual exhibits a “semantic accent” when they comprehend or use a word in one language in a way that is influenced by knowledge of its translation equivalent. Semantic accents are well-captured by feature-based models, such as the Distributed Conceptual Feature model and the Shared (Distributed) Asymmetrical model, however, few empirical studies have used semantic features to provide direct evidence for these models. The goal of this thesis is to use a feature-based approach to identify conceptual differences in translation equivalent words …

Universal Features In Phonological Neighbor Networks, Kevin S. Brown, Paul D. Allopenna, William R. Hunt, Rachael Steiner, Elliot Saltzman, Ken Mcrae, James S. Magnuson

Psychology Publications

Human speech perception involves transforming a countinuous acoustic signal into discrete linguistically meaningful units (phonemes) while simultaneously causing a listener to activate words that are similar to the spoken utterance and to each other. The Neighborhood Activation Model posits that phonological neighbors (two forms [words] that differ by one phoneme) compete significantly for recognition as a spoken word is heard. This definition of phonological similarity can be extended to an entire corpus of forms to produce a phonological neighbor network (PNN). We study PNNs for five languages: English, Spanish, French, Dutch, and German. Consistent with previous work, we find that …


Dual Route Model Of Idiom Processing In The Bilingual Context, Tianshu Zhu Jun 2018

Dual Route Model Of Idiom Processing In The Bilingual Context, Tianshu Zhu

Electronic Thesis and Dissertation Repository

The dual route model predicts that idiomatic phrases show a processing advantage over matched novel phrases. This model postulates that familiar phrases are processed by a faster direct route, and novel phrases are processed by an indirect route. This thesis investigated the role of familiar form and concept in direct route activation. Study 1 provided norming evidence for experimental stimuli selection. Study 2 examined whether direct route can be activated for translated Chinese idioms in Chinese-English bilinguals. Bilinguals listened to the idiom up until the last word (e.g., draw a snake and add), then saw either the idiom ending (e.g., …


The Relationship Between Implicit And Explicit Processing In Statistical Language Learning, Nicolette B. Noonan Jun 2014

The Relationship Between Implicit And Explicit Processing In Statistical Language Learning, Nicolette B. Noonan

Electronic Thesis and Dissertation Repository

Statistical language learning is an implicit process wherein language learners track sequential statistics in fluent speech, and may it facilitate the learning of word boundaries. This process is well studied, however, the cognitive mechanisms supporting it remain poorly understood. The present thesis investigated whether domain-specific or cross-domain explicit working memory engagement would impair implicit statistical learning of word boundaries in fluent speech. Participants (n = 110) were exposed to an implicit statistical word segmentation paradigm while concurrently engaged in no other task (control), or an explicit domain- specific (verbal) or cross-domain (visuospatial) working memory task of either low- or high- …


Cultural Brokering And Bicultural Identity: An Exploratory Study, Jorida Cila, Richard Lalonde, Zohrah Haqanee Apr 2011

Cultural Brokering And Bicultural Identity: An Exploratory Study, Jorida Cila, Richard Lalonde, Zohrah Haqanee

Western Migration Conference Series

Abstract: Cultural brokering refers to a process where individuals mediate between two parties that are experiencing some type of cultural misunderstanding. Our exploratory study indicates that cultural brokering is a diverse experience that spans the boundaries of one’s family and includes various norms, values and traditions.
