Physiological Processes During Reading, Elizabeth Morrey, Emma Smith, Catherine Bohn-Gettler, Jennifer Schaefer

Celebrating Scholarship and Creativity Day (2018-)

There are many different variables that can impact reading comprehension, such as reading level, emotional state, and the content of the text itself. For example, if a text contains inconsistencies (e.g., when a key moment in the text does not align with the information presented earlier in the story), processing slows as readers attempt to resolve the inconsistency. However, little is known about the connection between processing inconsistent versus consistent passages and physiological responses in the body. The goal of this study is to examine whether reading narrative texts containing inconsistent and/or consistent information elicits sympathetic nervous system activation, as …

Role Of Ectopic Olfactory Receptors In The Regulation Of The Cardiovascular-Kidney-Metabolic Axis, Mitchell R Beito, Sadia Ashraf, Dorcas Odogwu, Romain Harmancey

Faculty, Staff and Student Publications

Olfactory receptors (ORs) represent one of the largest yet least investigated families of G protein-coupled receptors in mammals. While initially believed to be functionally restricted to the detection and integration of odors at the olfactory epithelium, accumulating evidence points to a critical role for ectopically expressed ORs in the regulation of cellular homeostasis in extranasal tissues. This review aims to summarize the current state of knowledge on the expression and physiological functions of ectopic ORs in the cardiovascular system, kidneys, and primary metabolic organs and emphasizes how altered ectopic OR signaling in those tissues may impact cardiovascular-kidney-metabolic health.

Formal Bayesian Approaches To The Sense And Grappa Parallel Fmri Reconstruction Techniques Along With Their Combination, Chase Joseph Sakitis

Dissertations (1934 -)

In fMRI, capturing cognitive temporal dynamics is dependent on how quickly volume brain images are acquired. The sampling time for an array of spatial frequencies to reconstruct an image is the limiting factor in the fMRI process. Parallel imaging techniques Sensitivity Encoding (SENSE), which operates in the image space domain, and GeneRalized Autocalibrating Partial Parallel Acquisition (GRAPPA), which operates in the spatial frequency domain, have been utilized to greatly reduced image acquisition time. In SENSE image reconstruction, coil sensitivities are estimated once from a priori calibration images and used as fixed “known” coil sensitivities for image reconstruction of every subsequent …

Research Publications (2021 to 2025)

The color change of oil palm fresh fruit bunches (FFB) is one of the important parameter for harvesting decisions. However, human visual identification is prone to errors due to uncontrolled ambient lighting and the far distance of fruit bunches on tall palm trees. These errors can lead to inaccurate harvesting and significant revenue loss. This study introduces a laser remote sensor for non-destructive FFB ripeness assessment. Based on the unique spectral reflection curves of the FFO at different ripeness, laser modules at three different wavelenghts (visible-NIR region) have been employed for the measurement. The photodetector and laser sources are configured …

Galactic cosmic rays (GCRs) are charged particles that reach the heliosphere almost isotropically in a wide energy range. In the inner heliosphere, the GCR flux is modulated by solar activity so that only energetic GCRs reach the lower layers of the solar atmosphere. In this work, we propose that high-energy GCRs can be used to explore the solar magnetic fields at low coronal altitudes. We used GCR data collected by the High-Altitude Water Cherenkov observatory to construct maps of GCR flux coming from the Sun’s sky direction and studied the observed GCR deficit, known as Sun shadow (SS), over a …

Everyday Amnesia: Residual Memory For High Confidence Misses And Implications For Decision Models Of Recognition, Christopher J. Berry, David R. Shanks

School of Psychology

Despite studying a list of items only minutes earlier, when reencountered in a recognition memory test, undergraduate participants often say with total confidence that they have not studied some of the items before. Such high confidence miss (HCM) responses have been taken as evidence of rapid and complete forgetting and of everyday amnesia (Roediger & Tekin, 2020). We investigated (a) if memory for HCMs is completely lost or whether a residual memory effect exists and (b) whether dominant decision models predict the effect. Participants studied faces (Experiments 1a, 2, and 3) or words (Experiment 1b), then completed a singleitem recognition …

"A Ghostly Roll Of Drums Remorselessly Beat The Measure Of Life": Mrs. Ramsay's Mediation Of Time And Memory In Virginia Woolf's To The Lighthouse, Kirsten Walker Burningham

Theses and Dissertations

Virginia Woolf declares she was "obsessed" with her mother's presence. Though Julia Stephen died when Woolf was only thirteen, Woolf spent years negotiating her mother's astonishing influence, culminating in her novel To the Lighthouse. How does one square Woolf's obsession with her Victorian mother considering Woolf's progressive and feminist ideologies? I argue that Mrs. Ramsay--and by extension Julia Stephen--mediated time for their children as a byproduct of their role as maternal caregivers. This mediation is presented as an atmospheric quality or ambience as well as an intervention between subjective experiences and objective measures of time. The measurement and psychology of …

A Corpus Study Of The Effects Of Information Packaging On The Position Of Siempre And Nunca In The Spanish Verb Phrase, Rebekah Geddes

Theses and Dissertations

In Spanish, time adverbs show variability in their position with respect to the modified verb. This thesis investigates the effect of information packaging on the position of VP time-adverbs of frequency. Data were drawn from the Davies WEB Dialects Corpus. Two high-frequency verbs (dar and decir), as well as some of their less frequent near-synonyms (expresar, declarar, mencionar vis-à-vis decir, and ofrecer, entregar, and regalar vis-à-vis dar) were examined in relation to the adverbs siempre and nunca. The data show that when VP adverbs are part of sentence focus and do not have any special emphasis, they are found in …
