The Effects Of Categorization On Memory, Logan Armstrong Apr 2011

The Effects Of Categorization On Memory, Logan Armstrong

Undergraduate Student Symposium

The purpose of this study was to explore the effects of categorization on our ability to remember events and objects. This is an important question because little research has tested the notion that the ability to categorize helps produce better memory. Morris & Baker-Ward (2007) studied a similar question when they examined whether having the vocabulary to describe an experience affected the ability to remember that experience. Specifically, they tested whether infants who had learned their colors prior to participating in an experiment involving different colored bubbles would recall the experiment better than those who learned the colors after the …

On Parmenides’ Reality, Nathaniel Dolan Apr 2011

On Parmenides’ Reality, Nathaniel Dolan

Undergraduate Student Symposium

The treatment being submitted here for the Farquhar College of Arts and Sciences Undergraduate Student Symposium began quite simply in the form of a journal entry submitted as one of the required elements of Dr. Toscano’s Introduction to Philosophy (PHIL 1010) in the 2010 fall term. The professor’s review and critique of that original work (which was comparably brief compared to this final edition) produced remarks from Dr. Toscano that motivated me to reevaluate my own interpretations of the proposition on Reality put forth by Parmenides of Elea in the fifth century BCE. Having studied philosophy as a personal interest …

More Than Just A Memory, Sebastian Acosta-Nijamkin Apr 2011

More Than Just A Memory, Sebastian Acosta-Nijamkin

Undergraduate Student Symposium

“More than just a memory” is a film about love and friendship. Ethan is confronted with a tough decision: whether to tell the girl he loves how he really feels, or whether to accept the fact that she loves someone else and that Ethan will only be a friend in her eyes. Throughout the film, Ethan is driving in a car, and flashbacks of the night where he chose to be just a friend keep entering his mind. That night he made a choice -- a choice that would change his life forever. The film is directed by Sebastian Acosta-Nijamkin.

Cognitive Inhibition In Bilinguals Vs. Monolinguals, Juliana Acosta, Raquel Chocron, Jacqueline Pablos Apr 2011

Cognitive Inhibition In Bilinguals Vs. Monolinguals, Juliana Acosta, Raquel Chocron, Jacqueline Pablos

Undergraduate Student Symposium

Bilingualism has been linked to enhanced cognitive abilities and these enhanced abilities are believed to be mediated by the same frontal lobe system that controls language output in bilinguals. Moreover, recent research suggests that this bilingual advantage may be moderated by degree of balance between the two languages such that those who are equally proficient in their two languages show the best performance on cognitive tasks compared to unbalanced bilinguals and monolinguals. For instance, results from one study revealed that balanced bilinguals showed significantly fewer errors on the Wisconsin Card Sorting Test (WCST) than unbalanced bilinguals. Thus, the purpose of …

Tmnt: Dynamic Models Of Cancer And Hiv, Christina Gobin, Emily Nguyen, Fayssa Salomon, Arash Nasajpour

Undergraduate Student Symposium

Differential equations are used to build dynamic mathematical models for systems and nonlinear phenomena, which dynamically change with time. Ordinary differential equations describe a relation that contains functions of only one independent variable, and one or more of their derivatives with respect to that variable. Applications of those models are found in biological systems. In one study, homogeneous mathematical models are used to describe the interactions between cancerous cells and the immune system. Modeling using differential equations will allow better understanding of the behavior and spreading of those malignant cells. The models will investigate the dynamics of populations of cancer …

The Impact Of Psychological Stress On An Acute Stress Challenge: An Investigation Into Biochemical, Social And Personality Correlates, Tatiana Viena, Isabelle Barbu

Undergraduate Student Symposium

Stress exposure activates a variety of physiological coping systems. While acute stress responses are considered important for healthy coping, overexposure to stress results in an alteration of the functioning of the stress (HPA) axis, leading to a variety of deleterious psychological and physiological effects. For that reason, understanding and explaining these mechanisms is essential. Here, we sought to determine whether chronic psychological (examination) stress would result in a decreased ability to mount an acute stress and immune response. We also assessed locus of control and social support measures. Thirty subjects participated in 2 sessions (baseline and examination week) in which …

The Effects Of Sugar Substitutes On Gene Expression In Saccharomyces Cerevisiae, Hannah Bromberg Apr 2011

The Effects Of Sugar Substitutes On Gene Expression In Saccharomyces Cerevisiae, Hannah Bromberg

Undergraduate Student Symposium

Sugar substitutes are marketed as being healthier than sucrose (table sugar). Within this experiment, information about how table sugar and three different sugar substitutes, Splenda (sucralose-based), Truvia (stevia-based), and Equal (aspartame-based), affect gene expression in yeast was examined. Since the genomes of yeast and humans are approximately 30% similar, the specific genes selected for analysis in yeast overlapped with genes that are expressed in humans. Thus, Saccharomyces cerevisiae (Baker’s yeast) was used as a model eukaryotic organism in order to examine the effects of sugar substitute exposure on gene expression. The yeast was grown under four different conditions: 1) A …

Singles View Other Singles As Sexy: The Influence Of Relationship Status On Judgments Of Attractiveness, Jenna Wells Apr 2011

Singles View Other Singles As Sexy: The Influence Of Relationship Status On Judgments Of Attractiveness, Jenna Wells

Undergraduate Student Symposium

Previous studies on whether people find single or non-single opposite-sex targets more attractive are inconsistent (e.g., O’Hagen et al., 2003; Bressan & Stranieri, 2008; Uller & Johansson, 2003); these effects may vary according to social and hormonal factors (e.g., Gangestad et al., 2004). We propose that participants’ own relationship status may influence their judgments of the attractiveness of single and non-single people. In the present study, 43 participants each rated the attractiveness of ten “profiles,” using a between-participants design. Each profile consisted of a photograph and short personal description of a young opposite-sex adult. Half the profiles were depicted as …

Crystalline Metal-Organic Frameworks Drug Transfer, James M. Brandes Apr 2011

Crystalline Metal-Organic Frameworks Drug Transfer, James M. Brandes

Undergraduate Student Symposium

A relatively new type of chemical compound is finding application in such areas as gas storage, and drug delivery. Metal-organic frameworks, or MOF’s, are rigid structures with large cavities which other molecules can occupy for later release and use. We are studying the properties of new MOF’s based on copper and organic molecules known as BAII’s. In at least one case it has been demonstrated that these frameworks are capable of adsorbing, and later desorbing, host molecules. This makes them candidates for drug delivery and gas storage. The synthesis, characterization and adsorption properties of one framework will be discussed. A …

Peace Through Hostility: The Beats' Call For Equality Through Aggressive Poetic Imagery, Dan Abella Apr 2011

Peace Through Hostility: The Beats' Call For Equality Through Aggressive Poetic Imagery, Dan Abella

Undergraduate Student Symposium

This paper focuses on the poetic techniques of two Beat poets, Lenore Kandel and Allen Ginsberg, whose impressionistic, caustic poetry is in some ways representative of the entire Beat movement. Kandel's poems ring with overt sexual overtones, seemingly unconcerned with respect to morality or grace, invoking instead shocking and disturbing images. In her poetry is an intrepid protest of violence and conformity through the paradoxical use of violent description. Like the other Beat poets, she often refused to compromise in either structure or content, adopting a flowing, free-verse form. Allen Ginsberg's poetry employs the same modes: free verse, shocking context, …

Myh16 Masticatory Gene Mutation Correlates With The Evolution Of Human Morphological Cranial Capacity, Renee Michelle Potens Apr 2011

Myh16 Masticatory Gene Mutation Correlates With The Evolution Of Human Morphological Cranial Capacity, Renee Michelle Potens

Undergraduate Student Symposium

In the late Miocene, Homo sapiens encephalization accelerated simultaneously with an anatomic craniofacial transformation, associated with a shift towards a gracilization pattern of diet. Hansell H. Stedman has discovered a deleterious masticatory gene mutation responsible for jaw muscle development that is found in all modern human populations. This gene is functionally conserved in all non-human primates such as chimpanzees and extinct Hominidae species such as Australopithecus and Paranthropus, and is only found in its mutated, non-functional state in humans. The myosin heavy chain (MYH16) inactivation occurred after the divergence of the phylogenic lineages leading to humans and …

The Occurrence Of Helicosporidium In Freshwater Bodies In South Florida, Jhanelle Dawes Apr 2011

The Occurrence Of Helicosporidium In Freshwater Bodies In South Florida, Jhanelle Dawes

Undergraduate Student Symposium

Helicosporidium is a mosquito pathogen found in most South Florida water ecosystems. It is composed of four cells and related to green algae but is non- photosynthetic. It has been proven to be a vector control agent and has therefore shown the potential to eradicate mosquito-borne diseases. However, barely any biogeographical and ecological data regarding Helicosporidium exists. In order to determine the occurrence of Helicosporidium in environmental freshwater samples, water samples were collected from a local south Florida natural freshwater body. The metagenomic DNA extraction and specific amplification of Helicosporidium 18S rDNA genes using Polymerase Chain Reaction were then performed …

The Influence Of Emotional Stimuli On Attention Sharing In A Dual Modality Erp Paradigm: Effects Of Varying Interstimulus Intervals, Amanda Lynch Apr 2011

The Influence Of Emotional Stimuli On Attention Sharing In A Dual Modality Erp Paradigm: Effects Of Varying Interstimulus Intervals, Amanda Lynch

Undergraduate Student Symposium

A large and growing body of evidence demonstrates that attention is preferentially allocated to stimuli with emotional content. Emotionally negative stimuli serve as a mechanism of biological preparedness to enhance attention. In agreement with this idea, previous studies looking at the influence of emotional pictures on tone processing showed that the ERP measures of cognition was reduced when participants were exposed to an emotional picture with intermittent auditory startle probes We hypothesized that if an auditory oddball (attention capturing) stimulus was placed in the same perceptual time frame as a preceding emotional picture, the auditory stimulus would then share attention …
