How Do We Represent Possibilities In The Visual World? — An Analysis Of Amodal Completion Under Cognitive And Perceptual Load., Camden Parker
How Do We Represent Possibilities In The Visual World? — An Analysis Of Amodal Completion Under Cognitive And Perceptual Load., Camden Parker
Dartmouth College Undergraduate Theses
How do cognitive and perceptual load affect the way we experience the world when the visual scene is incomplete or partially occluded? The present study seeks to answer this question with a series of experiments based on primed matching, amodal completion, and load theory. In Experiment 1, we replicated results that amodal completion is automatic and supports multiple possible completions. In Experiment 2, we found that working memory load decreases the priming effects of both partially occluded and fully visible shapes. In Experiment 3, we found that perceptual load decreases the priming effect of partially occluded shapes more so than …
Possibility Is Not A Luxury: The Role Of Identity In Representations Of Possibility, Hannah M. Lebaron
Possibility Is Not A Luxury: The Role Of Identity In Representations Of Possibility, Hannah M. Lebaron
Dartmouth College Undergraduate Theses
In what ways are our expectations of others and their behaviors limited by the ways they are identified? Broadly, this project asks how identity traits are considered across judgments about which social roles people can assume. This work is an interdisciplinary project that exists within the fields of both Cognitive Science and Women’s, Gender, and Sexuality Studies. As such, the first chapter explores the central issues of identity conception from the perspective of feminist theory, including a discussion of category destabilization, intersectionality, and knowledge production in the context of feminist science studies. 4 empirical studies were launched with methods informed …
Probing Nlp Conceptual Relatedness Judgments Through The Word-Based Board Game Codenames, Tracey Mills
Probing Nlp Conceptual Relatedness Judgments Through The Word-Based Board Game Codenames, Tracey Mills
Dartmouth College Undergraduate Theses
In this paper I evaluate the ability of different Natural Language Processing (NLP)
techniques to make human-like word relatedness judgements in a variant of the word-based board game Codenames. I analyze a variety of statistical and knowledge based approaches, combinations of these, and techniques for incorporating the wider game context into relatedness judgements. While no approach explored here reaches human performance, simple word embedding based approaches incorporate a surprising amount of the useful information captured by other techniques. I attempt to characterize the limitations of these approaches in relation to human game play, although differences are largely not systematic. Finally, …
Destabilizing Terrorist Networks, John Keane
Destabilizing Terrorist Networks, John Keane
Dartmouth College Undergraduate Theses
Terrorism is a threat to global security and instills fear in the lives of people across the world. Over the past decades, billions in \$USD have been invested in counter-terrorism efforts. One approach to counter-terrorism is to destabilize terrorist organizations such that they are less effective at carrying out attacks. Previous work has investigated how to best proceed in this direction, such as which terrorists to target. Terrorist organizations have also been modeled as networks, where nodes can represent factions and/or terrorists. Research has been done to understand the network dynamics and link the structure of such networks to their …
