Subjective Value Of Previous Item Is Encoded During Valuation In Event-Related Potentials, Madeline Valdez
Subjective Value Of Previous Item Is Encoded During Valuation In Event-Related Potentials, Madeline Valdez
CMC Senior Theses
Research in economics and neuroscience has shown that an item’s value is subjective, in that it depends on the circumstances and preferences of the observer rather than the item’s inherent properties. In particular, value can be affected by the context in which an item is presented: for example, an apple might look more appealing if it is offered right after something less tasty, such as broccoli, than after something tempting like chocolate cake. Consistent with this idea, studies using invasive electrophysiology have shown that value signals corresponding to the current item are modulated by the value of the previously encountered …
Diversifying Participation: The Rarity Of Reporting Racial Demographics In Neuroimaging Research, Madeline Goldfarb
Diversifying Participation: The Rarity Of Reporting Racial Demographics In Neuroimaging Research, Madeline Goldfarb
Pitzer Senior Theses
Background: Functional neuroimaging techniques have been instrumental to progress in the cognitive and behavioral sciences; however, their increasing prevalence has evoked conversations concerning limitations associated with reproducibility and bias (Gilmore et al., 2017). While the literature has explored several mechanisms driving issues of replicability, few discussions have considered the effects of confounding social and environmental variables such as age, sex, socioeconomic status, and race (Sauce & Matzel, 2013). The prevailing racial, cultural, and socioeconomic bias in scientific research and the methodological limitations of EEG perpetuate racial and ethnic homogeneity in participation, eliciting qualms regarding the generalizability of findings (Henrich et …
The Characterization Of Alzheimer’S Disease And The Development Of Early Detection Paradigms: Insights From Nosology, Biomarkers And Machine Learning, Isabel Milano
CMC Senior Theses
Alzheimer’s Disease (AD) is the only condition in the top ten leading causes of death for which we do not have an effective treatment that prevents, slows, or stops its progression. Our ability to design useful interventions relies on (a) increasing our understanding of the pathological process of AD and (b) improving our ability for its early detection. These goals are impeded by our current reliance on the clinical symptoms of AD for its diagnosis. This characterizations of AD often falsely assumes a unified, underlying AD-specific pathology for similar presentations of dementia that leads to inconsistent diagnoses. It also hinges …
Global Consciousness: A Functionalist Neurophilosophical Perspective, Connor C. Bowen
Global Consciousness: A Functionalist Neurophilosophical Perspective, Connor C. Bowen
CMC Senior Theses
The purpose of this thesis is to explore a thought-provoking consequence of the functionalist theory of mind. Given the current organizational structure of Earth and field theories of consciousness in neuroscience, Earth is probably conscious. The argument is explored through an examination of the current organizational structure of Earth and field theories of consciousness in neuroscience, which leads to the conclusion that Earth is conscious. Various theories of mind have been proposed by neuroscientists and philosophers alike in an attempt to qualify what consciousness is and what provides the basis for consciousness to occur. Support, in the form of data …
An Exploration Of The Adaptive Functions Of Dreams And Empirically-Based Methods Of Dream Interpretation, Isaac Roberts
An Exploration Of The Adaptive Functions Of Dreams And Empirically-Based Methods Of Dream Interpretation, Isaac Roberts
CMC Senior Theses
This paper presents a meta-analysis of dream theory within psychology and neuroscience. The questions it attempts to answer are: what is the neuroscientific basis of dreaming? Why do dreams exist (do they have an adaptive function)? Could dreams possibly have no function? And, what is the best way to interpret a dream? The current analysis presents various theories relevant to each of these questions and compares their viability. It also briefly examines the origins of psychological thought on dreams and, towards the end, outlines the steps and empirical support for a well-regarded method of dream interpretation known as the cognitive …
Creativity, Laterality And Critical State Balance In Learning, Jenny Rock, Asher Flatt
Creativity, Laterality And Critical State Balance In Learning, Jenny Rock, Asher Flatt
The STEAM Journal
Understanding the intersecting cognitive pathways that are integral to ways of thinking, creating and functioning in both art and science is an important grounding for a STEAM educational approach. We combine three divergent concepts, including creativity, hemisphere laterality, and critical state theory, to argue for a more balanced approach to learning as part of a modern meaning-centered education in STEAM. Reviewing the concept of hemisphere laterality, or how the two hemispheres of our brain have different (though not disconnected) ways of processing sensory information, we note how these two means of interpreting the world have become unbalanced in traditional modes …
Consumer Neuroscience: A Multi-Disciplinary Approach To Marketing Leveraging Advances In Neuroscience, Psychology And Economics, Bridget E. Blum
Consumer Neuroscience: A Multi-Disciplinary Approach To Marketing Leveraging Advances In Neuroscience, Psychology And Economics, Bridget E. Blum
CMC Senior Theses
For decades, neuroscience has greatly contributed to our foundational understanding of human behavior. More recently, the findings and methods of neuroscience have been applied to study the process of decision-making in order to offer advanced insights into the neural mechanisms that influence economic and consumer choices. In this thesis, I will address how customized marketing strategies can be enriched through the integration of consumer neuroscience, an integrative field anchored in the biological, cognitive and affective mechanisms of consumer behavior. By recognizing and utilizing these multidisciplinary interdependencies, marketers can enhance their advertising and promotional mix to elicit desired neural and affective …
Are Coloring Books Really Just For Kids? Investigating Possible Effects Of Specific Pattern Coloring On Conceptual, Physiological And Behavioral Aspects Of Anxiety, Hannah Taylor
Scripps Senior Theses
This study examined the role of specific pattern coloring, such as coloring books for adults, on conceptual, behavioral and physiological measures of anxiety. Undergraduate female students (n = 8) had ECG electrodes and a respiration belt attached and completed the State Trait Anxiety Inventory (STAI) at five time points; at baseline, after an initial autobiographical anxiety induction, following a passive relaxation condition, after a repeat induction and then after a coloring condition. The participants were randomly split into a control and experimental group; the control group free colored while the experimental group colored in a mandala pattern. Participants had the …
Role Of Alpha Oscillations In Reweighting Multiple Attributes During Choice, Samuel I. Dunham
Role Of Alpha Oscillations In Reweighting Multiple Attributes During Choice, Samuel I. Dunham
CMC Senior Theses
In our everyday lives, we must often weigh the different attributes of items in order to select the item that best fits our current goals, allowing us to make optimal decisions. Construal Level Theory proposes a psychological mechanism for re-weighting attributes, utilizing selective attention as the process by which we implement self-control. It has been hypothesized that switching attention between attributes is facilitated by the suppression of cortical oscillations over posterior brain regions within the alpha (8-12 Hz) frequency range. To test this idea, we re-examined previously collected whole-brain electroencephalography (EEG) data from a dietary choice experiment in which participants …
Reducing Subjectivity: Meditation And Implicit Bias, Diana M. Ciuca
Reducing Subjectivity: Meditation And Implicit Bias, Diana M. Ciuca
CMC Senior Theses
Implicit association of racial stereotypes is brought about by social conditioning (Greenwald & Krieger, 2006). This conditioning can be explained by attractor networks (Sharp, 2011). Reducing implicit bias through meditation can show the effectiveness of reducing the rigidity of attractor networks, thereby reducing subjectivity. Mindfulness meditation has shown to reduce bias from the use of one single guided session conducted before performing an Implicit Association Test (Lueke & Gibson, 2015). Attachment to socially conditioned racial bias should become less prevalent through practicing meditation over time. An experimental model is proposed to test this claim along with a reconceptualization of consciousness …
Examining The Intersection Of The Cognitive Advantages And Disadvantages Of The Bilingual Brain, Irina Rabkina
Examining The Intersection Of The Cognitive Advantages And Disadvantages Of The Bilingual Brain, Irina Rabkina
Scripps Senior Theses
Two conflicting findings characterize cognitive processing accompanying bilingualism. The “bilingual advantage” refers to improved cognitive performance for bilingual compared to monolingual participants. Most bilingual advantages fall under the umbrella of cognitive control mechanisms, most frequently demonstrated using the Stroop task and the Simon task (e.g., Bialystok, 2008; Coderre, Van Heuven, & Conklin, 2013). The “bilingual disadvantage,” on the other hand, refers to bilinguals’ diminished performance on tasks that require word retrieval or switching between languages. This study examined the intersection of the bilingual advantage and the bilingual disadvantage to investigate whether they stem from a single cognitive control process. The …
Navigating The Diverse Dimensions Of Stereotypes, With Domain Specific Deficits: Processes Of Trait Judgments About Individuals With Disabilities, Christina G. Boardman
Navigating The Diverse Dimensions Of Stereotypes, With Domain Specific Deficits: Processes Of Trait Judgments About Individuals With Disabilities, Christina G. Boardman
Scripps Senior Theses
Stereotype groups are interrelated. For example, in Australia, New Zealand, and the United States, racial minorities are referred to special education at a much higher rate than are majority racial groups (Tse, Lloyd, Petchkovsky, and Manaia, 2005; Harry, Arnaiz, Klingner, Sturges, 2008). The Stereotype Content Model describes stereotype relationships in terms of an interaction between competence and warmth. Warmth is the more consistent dimension. The nature of competence remains elusive (Fiske, Cuddy, and Glick, 2007; Fiske, Cuddy, Glick, and Xu, 2002). Knowledge of relationships between stereotype groups, which themselves may be effects of bias, could factor into observed competence effects. …
Effects Of Cannabidiol On Mk-801-Induced Locomotor Sensitization In Mice, Sara K. Cronin
Effects Of Cannabidiol On Mk-801-Induced Locomotor Sensitization In Mice, Sara K. Cronin
Scripps Senior Theses
Previous research has shown that cannabidiol (CBD), a non-psychoactive compound in the hemp plant Cannabis sativa, may be useful in treating drug craving, one of the hallmarks of drug addiction. However, the neural mechanism by which CBD attenuates craving is poorly understood. Studies from other laboratories have shown that neuroplastic changes associated with brain NMDA glutamate systems may at least partially serve as a neural mechanism for craving. In the current study, the noncompetitive NMDA receptor antagonist MK-801 maleate was used to induce locomotor sensitization, a form of NMDA glutamate-mediated neuroplasticity, in mice to test the sensitization-attenuating potential of …

Affective Decision-Making Predictive Of Chinese Adolescent Drinking Behaviors, Lin Xiao, Antoine Bechara, Jerry L. Grenard, Alan W. Stacy, Paula Palmer, Yonglan Wei, Yong Jia, Xiaolu Fu, C. Anderson Johnson
CGU Faculty Publications and Research
The goal of the current investigation was to address whether affective decision making would serve as a unique neuropsychological marker to predict drinking behaviors among adolescents. We conducted a longitudinal study of 181 Chinese adolescents in Chengdu city, China. In their 10th grade (ages 15–16), these adolescents were tested for their affective decision-making ability using the Iowa Gambling Task (IGT) and working memory capacity using the Self-Ordered Pointing Test. Self-report questionnaires were used to assess academic performance and drinking behaviors. At 1-year follow-up, questionnaires were completed to assess drinking behaviors, and the UPPS Impulsive Behavior Scale was used to examine …
Word Association Tests Of Associative Memory And Implicit Processes: Theoretical And Assessment Issues, Alan W. Stacy, Susan L. Ames, Jerry L. Grenard
Word Association Tests Of Associative Memory And Implicit Processes: Theoretical And Assessment Issues, Alan W. Stacy, Susan L. Ames, Jerry L. Grenard
CGU Faculty Publications and Research
Word association is one of the most commonly used measures of association in cognitive science. These tests have been used to infer association parameters in normative studies, to derive cues and primes used in diverse paradigms (semantic priming, cued recall, illusory memory), to test implicit memory in experimental studies, and to suggest the operation of implicit processes in nonexperimental work. This chapter briefly outlines some of the historical routes and current controversies about association and summarizes basic cognitive research applying associative tests. The authors then describe benefits and limitations of the tests, as well as implications for theory and interventions …
Age Differences In Behavior And Pet Activation Reveal Differences In Interference Resolution In Verbal Working Memory, Alan Hartley, John Jonides, Christina Marshuetz, Edward E. Smith, Patricia A. Reuter-Lorenz, Robert A. Koeppe
Age Differences In Behavior And Pet Activation Reveal Differences In Interference Resolution In Verbal Working Memory, Alan Hartley, John Jonides, Christina Marshuetz, Edward E. Smith, Patricia A. Reuter-Lorenz, Robert A. Koeppe
Scripps Faculty Publications and Research
Older adults were tested on a verbal working memory task that used the item-recognition paradigm. On some trials of this task, response-conflict was created by presenting test-items that were familiar but were not members of a current set of items stored in memory. These items required a negative response, but their familiarity biased subjects toward a positive response. Younger subjects show an interference effect on such trials, and this interference is accompanied by activation of a region of left lateral prefrontal cortex. However, there has been no evidence that the activation in this region is causally related to the interference …
Age Differences In The Frontal Lateralization Of Verbal And Spatial Working Memory Revealed By Pet, Alan Hartley, Patricia A. Reuter-Lorenz, John Jonides, Edward E. Smith, Andrea Miller, Christina Marshuetz, Robert A. Koeppe
Age Differences In The Frontal Lateralization Of Verbal And Spatial Working Memory Revealed By Pet, Alan Hartley, Patricia A. Reuter-Lorenz, John Jonides, Edward E. Smith, Andrea Miller, Christina Marshuetz, Robert A. Koeppe
Scripps Faculty Publications and Research
Age-related decline in working memory figures prominently in theories of cognitive aging. However, the effects of aging on the neural substrate of working memory are largely unknown. Positron emission tomography (PET) was used to investigate verbal and spatial short-term storage (3 sec) in older and younger adults. Previous investigations with younger subjects performing these same tasks have revealed asymmetries in the lateral organization of verbal and spatial working memory. Using volume of interest (VOI) analyses that specifically compared activation at sites identified with working memory to their homologous twin in the opposite hemisphere, we show pronounced age differences in this …
