Mechanisms Of False Memories In Bilinguals, Bianca Valentina Gurrola

Open Access Theses & Dissertations

Research on false memory in bilinguals has discovered that false memories can transfer across languages and occur at a higher rate than for within-language false memories (Marmolejo et al., 2009). However, the exact conditions that cause the stronger between-language false memory effect are not clear, nor is it clear how language proficiency influences the production of false memories. The present study had three goals. First, we tested whether the stronger between- language false memory effect relative to the within-language effect would replicate. Second, we examined whether bilinguals could integrate information across languages to form false memories by implementing a mixed-language …

Sources Of Top-Down Processing In Recognition Of Repeated Speech In Noise, Liam Gleason

Open Access Theses & Dissertations

Prior research has shown that repetition facilitates speech recognition in difficult listening environments, as indicated by more accurate reporting and lower subjective noise ratings. Both effects were found even when sentences were read at encoding, suggesting that the top-down processing involved comes from a modality-general level of representation (Gleason & Francis, 2021). We investigated whether this top-down processing comes from the semantic or lemma level of language representation. Bilingual participants listened to sentences in English and Spanish. At test, these sentences and new sentences were presented auditorily in English with background noise. After listening to each sentence, participants reported the …

Who Said What To Whom?: Contextual Memory Processes In Bilinguals, Naoko Tsuboi

Open Access Theses & Dissertations

Source memory is memory for sources of information (who gave the information), whereas destination memory is memory for destinations of information (to whom the information was given). Prior literature found that source memory exceeded destination memory, and destination memory was impaired remarkably under high cognitive demand tasks. These findings supported the attention hypothesis, the idea that greater attentional resource availability leads to better source and destination memory. The current study extended prior source and destination research to bilingualism because bilinguals are thought to have a greater attention control ability than monolinguals. In the only published study to compare bilingual and …

So I Was, 'Like', Totally Buggin’ – Evidence For The Role Of Attention On Entrainment From Discourse Particles, Rachel L. Williams

Open Access Theses & Dissertations

In this study, we investigated the role of attention for entrainment during production and comprehension using the discourse particle like. We tested two main hypotheses – that entrainment to discourse particles, even if relatively implicit, requires some attentional resources, versus that it requires little (if any) attention. In two experiments, participants read a short story and retold it (baseline retelling phase), then read another short story and listened to a recording of it (priming phase), and then read and retold a third story (target retelling phase). In Experiment 1, half of the participants simultaneously navigated a busy pedestrian zone in …

All these new devices in our homes make our day-to-day lives easier and more comfortable with less effort on our part, converting our simple houses into smart homes. This increase in inter-connectivity brings multiple benefits including the improvement in energy efficiency in our homes, however it also brings with it some potential dangers since more points of connection mean more potential vulnerabilities in our grid. These vulnerabilities bring security …

Bilingual Children's L1 And L2 Word Frequency Effects: The Role Of Individual Differences, Astrid Michelle Portillo

Open Access Theses & Dissertations

Bilingualism continues to grow among the world's population. Nevertheless, most research studies on language processing have focused on monolingual individuals, leaving questions about how language processing unfolds in bilingual individuals. Here, we investigated how individual differences in bilingual experience, indexed by current L2 exposure, impact eye movement measures of reading fluency, indexed by word frequency effects, in an understudied population: bilingual children. Prior eye movement research involving bilingual younger adults (aged 18 to 30) has reported a trade-off in L1 and L2 word frequency effects with greater levels of current L2 exposure (Whitford & Titone, 2012, 2017). We wanted to …

Association Between Adverse Childhood Experiences, Resilience And Mental Health Among College Students In The El Paso Texas Border Region, Maribel G. Dominguez

Open Access Theses & Dissertations

Purpose: The purpose of this study is to explore the relationship between adverse childhood experiences (ACEs), mental health and resilience among adults living in the United States - Mexico Border region. Background: Numerous studies have investigated the negative impact of ACEs on adult mental health, but the concept of resilience as a protective factor for mental health has limited consideration in ACE treatment interventions. The proposed study addresses this gap in knowledge by investigating relations between ACEs, resilience, and mental health in the understudied U.S - Mexico Border population. Method: An online survey was administered to 221 university students to …

Cross-Language Activation And Integration Of Concepts In Text Passages, Karly Meillyn Schleicher

Open Access Theses & Dissertations

Learning from text requires the ability to efficiently activate and retrieve relevant concepts from long-term memory and connect these with new information that is being presented in the text. It is assumed that memory representations built from text can be influenced by both surface level information (i.e., word forms), or deeper, conceptual level information. The goal of the present study was to investigate the role of surface level features (i.e., language) influence memory representations developed from text. By recruiting Spanish-English bilinguals, the present study investigated how surface level features from a reader's two lexicons influences the activation and integration of …

Concreteness, Frequency, And Bilingual Language Dominance: Implications For The Impact Of Context Availability In Explicit Memory, Randolph Taylor

Open Access Theses & Dissertations

One explanation for why concrete words are better recalled than abstract words is systematic differences across these word types in the availability of context information. In contrast, explanations for the concrete word advantage in recognition memory do not consider a possible role for context availability. Like concrete words, low-frequency words and L2 words also demonstrate item recognition advantages over high-frequency words and L1 words, respectively. Although the theories explaining these advantages do not explicitly discuss context availability, the mechanisms described suggest that context availability may play a role. The present study examined the extent to which context availability can explain …

Source Monitoring In Bilinguals, Renee Michelle Penalver

Open Access Theses & Dissertations

Source memory is memory for the context in which a particular target item is learned (Parker, 1995). The source-monitoring framework is the leading model of source memory (Johnson, Hashtroudi, & Lindsay, 1993). It remains unknown at what level context-to-word associations are made (e.g., at the word form level or conceptual level). Three experiments examined the effects of word frequency and language proficiency on source memory, with each experiment addressing one of the different types of source monitoring identified in this framework. In Experiment 1, we examined how language proficiency and word frequency affect external source discrimination. Participants had to discriminate …

Do Event Boundaries Influence Processing Of Concurrently Presented Information?, Omar Carrasco

Open Access Theses & Dissertations

During our everyday experiences, working memory representations of the current situation are updated at event boundaries, where meaningful perceptual or conceptual changes occur. These event boundaries lead to increases in perceptual processing, attention, activation of semantics and event schemas to generate a more accurate representation of what is currently happening. Previous literature has demonstrated that information embedded within an elapsing experience that is presented at event boundaries receives a processing advantage that leads to better memory for that information compared to information presented at non-boundary locations. However, it is not clear whether information presented concurrently but outside of the elapsing …

Bilingual Novel Word Learning In Sentence Contexts, Justin G. Lauro

Open Access Theses & Dissertations

According to the Instance-based framework of adult vocabulary learning, each time a learner encounters a new word in context, an episodic memory trace, containing the word itself and the surrounding context, is formed. Previous research has demonstrated an advantage in memory for words encountered in a variety of semantic contexts. This advantage occurs because distinctive contexts generate more distinctive memory traces. While research has demonstrated that a variety of contextual characteristics are encoded (e.g. semantic context, modality, and language), it is unknown whether varying the language context in which a word is encountered has a similar benefit on memory for …

Defining Moral Attitudes : An Examination Of The Structure And Consequences Of Moral Attitudes, Ciara Katelyn Kidder

Open Access Theses & Dissertations

The goals of this Dissertation were to contribute to the literature on the structure of moral attitudes and explore the consequences of moral attitudes on person perception. The goal of study 1 was to replicate and extend previous research examining the automatic nature of moral objectivity and moral universalism. In Study 1, there was no support for the relationship between morality and objectivity and morality and universality. Instead, the study demonstrated that sequential priming may be an ineffective methodology for measuring these relationships. The goal of study 2 was to examine the relationship between the similarity of participant attitude to …

Examining The Role Of Threat Processing In Memory Consolidation And Prejudice Formation, Stephanie Marie Reyes

Open Access Theses & Dissertations

Memory is a flexible system that integrates new incoming information into existing memory representations (Stickgold & Walker, 2007). Through sleep and over time, memories become stable via consolidation processes (Payne, Stickgold, Swanberg & Kensinger, 2008). Prejudice formation can occur through the consolidation of stereotype schemas. In a previous study Latino participants learned positive and negative trait information about in-group and out-group members (Enge, Lupo & Zárate, 2015). At test, participants responded more quickly to out-group targets paired with negative traits than in-group pairings with these traits. Findings indicate that participants also responded more quickly to in-group targets paired with positive …

The Window To The Bilingual Mind: Eye Movements Reveal Psycholinguistic Grain Unit Sizes Of Bilingual Spoken Word Recognition, Yu-Cheng Lin

Open Access Theses & Dissertations

Although there are common phonological units across different languages, previous studies have shown that individual differences of language proficiency affect sound unit preferences in monolingual and bilingual speakers. The cross-language lexical activation of phonological representations in bilingual minds can provide a great opportunity for testing hypotheses about how this key factor modulates the cross-linguistic phonological transfer across languages. In this study, I used the eye-tracking technique and quantitative methods (i.e., growth curve analysis and multilevel regression) to examine how individual differences in language proficiency affect cross-language phonological unit size transfer in Chinese-English bilinguals. Participants heard a spoken word and were …

Guilty By Association: Time-Dependent Memory Consolidation And The Generalization Of Person-Specific Traits To Other Group Members, Luke R. Enge

Open Access Theses & Dissertations

The following study investigated the extent to which time-dependent memory consolidation facilities the generalization of person-specific traits (individuated targets) to other, familiar social group members (familiar targets) Sixty-Nine (N = 69) participants learned to distinguish between two arbitrary groups, one positive and one negative. Participants learned the negative or positive information about a subset of the group members (individuated targets) and no individuating information about the familiar targets. Participants returned either without a time-delay containing sleep (2-6 hours after learning) or a time-delay with sleep (48 hours after learning). Results demonstrated that only after a time-delay containing sleep, negative information …

Strengthening Cognitive Development In Minority Populations: A Study Of The Beneficial Effects Of Bilingualism, Marisela Gutierrez

Open Access Theses & Dissertations

The long-term goal of this research is to better understand and characterize the "bilingual advantage" so that educational and child care institutions begin to recognize and encourage the active use of two languages to strengthen cognitive development in minority populations. The present study is one of the first one to include a very large sample of well-defined "active bilinguals" who, by objective measures, were determined to be bilingual and determined to engage in language switching on a daily basis. Another goal was to manipulate and activate in the laboratory what might be referred to as the "switching benefit." One hundred …

Assessing Naturalistic Decision Making By Experienced And Inexperienced Interrogators In High Stakes Interviews, Amy Bethany Ross

Open Access Theses & Dissertations

The current thesis aimed to improve the ecological validity of human intelligence interrogation research. Although field practitioners and researchers have worked together to improve the scientific validity and practical execution of interrogation techniques, research has yet to understand how, when and why interrogators implement such techniques. This thesis investigated the active decision making processes of interrogators that occur during high value interrogations. The theory of Naturalistic Decision Making was used to capture the naturalistic characteristics of high value interrogations- ambiguity, time pressure and high stakes. To capture the decision-making processes that are associated with skilled performance, this research conducted in-depth …

Adding Within-Utterance Emotion Decay For More Human-Like Dialog, Michael Hans Durcholz

Open Access Theses & Dissertations

While spoken dialog systems have been used for commercial applications for several decades, most commercial spoken dialog systems provide only simple information exchange capabilities. Emotion synthesis in spoken dialog systems has become an active research area recently, and use of emotion-adaptive dialog systems has demonstrated improvements in user experience and rapport. This thesis seeks to improve how emotions are conveyed in dialog systems to enable robust emotional support that improves user experiences with dialog systems and models human speech characteristics more accurately than current dialog systems.

Prior work with Gracie (GRAduate Coordinator with Immediate response Emotions), an emotion-adaptive dialog system, …

Implicit Attitudes Of Ethnicity And Language: Evaluative And Associative Priming, Eva Margarita De La Riva Lopez

Open Access Theses & Dissertations

Most members of minority groups belong to both an ethnic and a linguistic minority. The interplay between these two related yet independent constructs has not been explored. For this reason, this study examined language attitudes following the theoretical model of social categorization by using implicit measures. This study also investigated the implicit association between language and ethnicity. In this manner, the relationship that exists between attitudes towards minority groups and attitudes towards minority languages can be disentangled. A simultaneous study of implicit attitudes of ethnicity and language, and the association between ethnicity and language, may elucidate possible mechanisms involved in …

The Role Of Cross-Language Activation In Syntactic Ambiguity, Li-Hao Yeh

Open Access Theses & Dissertations

There is much evidence demonstrating that bilinguals activate lexical representations from both of their languages in a non-selective manner even in sentence context. Comparatively less research has examined the extent to which bilingual lexical representations interacts with syntactic processing in sentence context. The purpose of this study is to examine whether bilinguals' cross-language lexical activation could influence their resolution of syntactic ambiguity (e.g. relative clause attachment). Proper attachment of relative clauses (RC) to noun phrases is critical for accurate interpretation of syntactically ambiguous sentences. For instance, the sentence The robber shot the secretary of my husband who goes to work …

Bilingual Homonym Disambiguation At The Discourse Level, Yvette Aguilar Baca

Open Access Theses & Dissertations

The objective of this study was to investigate the effects of global context and local context on the time course of activation of cognate homonyms for bilingual readers. Of interest was whether meaning frequency, context, and cross-language activation modulated the time course of activation of the subordinate meaning of cognate homonyms. Also, whether the subordinate bias effect would be altered or even eliminated by the combined influence of such contextual factors and cross-language activation. Eye movements of Spanish-English bilinguals were measured using an eye-tracking device while they read English paragraphs. The paragraphs contained cognate homonyms (e.g. novel/novela), cognate non-homonyms (e.g. …

Indentifying And Understanding User Preferences In Generic Planning Tools, Grisel Ventura

Open Access Theses & Dissertations

Planning is an important cognitive work activity. To support this complex task, the development of planning tools is important to support people during decision-making and problem-solving tasks. Nowadays, a large number of manual and electronic tools support this complex activity; manual and electronic planning tools aid people in creating strategies for effective work performance. However, there is limited information on the design of generic planning tools people use for their activities, and why people choose to use the planning tool they do. Some examples of generic tools for planning are calendars, checklists, agendas, etc.

To answer this question, this research …

Intelligent Tutoring For Interviewing To Detect Deception: Can Investigators Be Trained To Attain And Detect Accurate Cues To Deception?, Justin Albrechtsen

Open Access Theses & Dissertations

The present study examined whether investigators can be trained to elicit and detect cues to deception. The study included two training conditions and a control condition. Participants in the virtual Human Intelligent Tutoring System (vHITS) conditions completed a training program for deception detection and investigative interviewing. The primary components of this training were one-on-one interaction with a virtual human and tutoring tailored to specific participant responses. Participants in the Computer Based Training (CBT) conditions completed a comparable training program for deception detection and investigative interviewing. However, this program provided a more passive training environment with no interaction between student and …

Developmental Variation In Children's Acquisition Of Metrical Structure: How Early Treatment Of Stressless Syllables Can Inform Phonological Theory, Clifford S. Jones

Open Access Theses & Dissertations

The present study uses 26 color photos to elicit a total of 14 words conforming to a very specific pattern: a stressless syllable word-initially, followed by a stressed syllable, and at most one more stressless syllable. This was found to be a particularly difficult metrical structure for the two- and three-year old participants to produce in an adult-like manner. Based on the findings that a fairly reliable (if language-particular) order of acquisition is observable for contrasts of both place and manner of articulation, the case is made for a system of six emergent features, which may be characterized as combinable …

Examination Of The Cognitive Mechanisms Underlying Evaluative And Semantic Priming Effects By Varying Task Instructions: An Erp Study, Jennifer Hilda Taylor

Open Access Theses & Dissertations

This study examined the cognitive processes that underlie stimulus identification and the activation of attitudes by investigating behavioral and psychophysiological effects in a priming paradigm. Cognitive mechanisms were investigated by examining evaluative and semantic priming effects on behavioral response times, the N400, and LPP event-related potential (ERP) components by varying tasks between-subjects. Participants either completed an evaluative task, a semantic task, or a feature-detection task. It was hypothesized that the behavioral evaluative priming effect would occur in the evaluative task and that the behavioral semantic priming effect would occur in the semantic and feature-detection tasks. The N400 was hypothesized to …

The Role Of Generation And Monitoring Processes In Governing The Paradoxical Effects Of Retrieval On Memory For Faces, Kyle Joseph Susa

Open Access Theses & Dissertations

Verbal descriptions of faces can at times impair and at other times facilitate subsequent face identification accuracy. Three experiments were conducted from a retrieval-based theoretical perspective to determine the underlying cognitive processes that can account for these paradoxical findings. Results demonstrated that the verbal description-identification relationship is analogous to other domains of memory where an initial retrieval of memory can have both positive and negative effects on subsequent retrieval attempts. Results of Experiment 1 showed that verbal facilitation is a product of self-generated descriptions that enrich the semantic encoding of the original memory trace. Experiments 2 and 3 demonstrated that …

Two Sides Of The Same Coin: Biculturalism, Cultural Ideologies, And Perceptions Of Cultural Change, Stephanie Ann Quezada

Open Access Theses & Dissertations

Ethnic minorities are adopting a bicultural identity to simultaneously identify with their heritage culture and mainstream American culture. While much research has investigated the extent to which ethnic majority and minority groups differentially respond to cultural ideologies, bicultural reactions to cultural ideologies remain uninvestigated. Bicultural individuals' differential endorsement of cultural ideologies has critical implications for implementation of assimilation and multiculturalism in multicultural societies. Therefore, the aim of the present study was to test the extent to which the salience of cultural identity predicts bicultural individuals' endorsement of assimilation and multicultural ideologies. Identity saliency was manipulated for bicultural Latino Americans and …

Getting To Know You: The Effects Of Familiarity And Time On Social Perception, Clarissa Arms Chavez

Open Access Theses & Dissertations

A new direction in social perception research is developed. The present research explored the impact of familiarity and time on social perception processes based on cognitive neuroscience models, social categorization models, and memory consolidation constructs. Familiarity was manipulated within an exposure task and time was manipulated by testing participants both 2-6 hr and 48 hr after the exposure task. Experiment 1 investigated the influence of familiarity and time on the argument of the automaticity of social categorization and associated stereotypes by testing the argument with two separate tasks. Experiment 1a tested the influence of familiarity and time on associated stereotypes …

Does Type Of Stimulus Influence Task-Irrelevant Evaluative Categorization Processes?, Guadalupe Corral

Open Access Theses & Dissertations

The effect of stimulus type on task-irrelevant evaluative categorization was examined in two separate studies by using the P3 component from event-related brain potentials. The first study presented idiosyncratic stimuli consisting of individuals that were rated by participants as either positive or negative within sequences of pictorial and verbal stimuli. The second study presented sequences of novel and familiar stimuli consisting of previously normed unattractive and neutral individuals. It was hypothesized that pictures would elicit task-irrelevant evaluative categorization processes and so would novel stimuli (relative to words and familiar stimuli, respectively). Task-irrelevance was examined by assessing P3 peak amplitude to …
