Assessing How Bilingual Experience Impacts Performance In Stimulus-Stimulus And Stimulus-Response Conflict Tasks, Christian Ruiz-Ortiz

Open Access Theses & Dissertations

Numerous studies have revealed that bilingual individuals outperform monolinguals in tasks requiring executive control. However, the exact impact of bilingualism on executive functions remains unclear due to inconsistent findings in the literature. These discrepancies may stem from factors such as participant demographics, variations in definitions and operationalizations of bilingualism, and task selection. To address these issues, we investigated the link between degree of balance and contextual use with the ability to address conflict across sensory modalities (auditory and visual) at different stages of processing. Rather than focusing on mean performance, this study investigated performance stability (coefficient of variation) over time …

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 …

Examining The Role Of Perceptual Biases In Health Care Utilization Among Adults, Sandra L. Oviedo Ramirez

Open Access Theses & Dissertations

A large body of literature has identified significant racial and ethnic disparities in health care and health outcomes. In an effort to gain an understanding of how to achieve health equity, it is crucial that we broaden our search for factors beyond access factors that may explain these observed disparities. The present study examined how cultural differences related to attention (context vs. focal) and attribution (internal vs. external) influence individuals' propensity to identify symptoms as potential markers of poor health, and ultimately, report less utilization of professional health care services. Using a community sample of 252 (n = 134 Latinos …

Hemispheric Asymmetry Of The Affective Priming Effect, David R. Herring

Open Access Theses & Dissertations

The present study examined the role of prime strength on the lateralized affective priming effect. Participants were presented unilateral primes (i.e., either to the left or right visual field) and then made evaluative decisions on centrally presented targets. Across both experiments, the affective congruity effect occurred for high, but not low, arousing primes. In Experiment 1, when stimuli were primes or targets but not both, the affective priming effect occurred in the right visual field (left hemisphere) for high arousing primes. However in Experiment 2, when stimuli were presented as both primes and targets receiving repeated parafoveal and foveal exposure …

The Role Of Perceptual Processes In The Use Of And Willingness To Use Professional Health Care Services, Luis Omar Rivera

Open Access Theses & Dissertations

To better address ethnic health disparities, it is imperative that we understand the psychological processes that shape people's use of and willingness to use professional health care services. The current research proposes and tests a model in which people's attentional orientation toward context discourages them from seeking professional health care services because (a) attentional orientation toward context encourages people to attribute symptoms of illness to external/environmental factors and (b) attributing symptoms of illness to external/environmental factors is associated with less use of professional health care services. The results of two studies show mixed support for the proposed model. Consistent with …

Attention Allocation And The Variability Of The Stereotype Priming Effect, Katherine R. White

Open Access Theses & Dissertations

The stereotype priming effect is assumed to be a rather uniform and robust effect. However, a closer look at the existing literature suggests that the `standard' stereotype priming effect may be more susceptible to variability than originally believed. In the present study, we sought to demonstrate that the stereotype priming effect displays significant variability in strength depending upon the level of attention allocated to the stereotype feature of interest. Participants were assigned to 1 of 3 conditions: a lexical decision task (LDT) condition, a pre-primed LDT condition, and a gender categorization condition. It was predicted that the stereotype priming effect …

Effects Of Concurrent Task Performance On Object Processing, Gabriela Durán

Open Access Theses & Dissertations

Most research on visual object identification focus on the bottom-up processes of the visual what? and where? pathways. However, such research has not been able to fully account for many visual abilities (e.g., identifying an object among many other objects and across changing conditions). Neurological evidence has shown that feedback from high-level areas (i.e., top-down processing) makes object processing more efficient. However, there are no behavioral studies that have tested this. Thus, four experiments used a concurrent n-back task to occupy higher-level areas and tested its effects on visual object processing relative to a number-repetition control task.

Experiment 1 examined …
