ETDs

This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

In an ever-faster world, products that are designed for enhancing the speed of a certain task can and are being designed in rapid iterations by means of adding or modifying features that impact the energetics, kinematics and kinetics of a given product. Given the ubiquity of said changes and the need to market these products in a very crowded marketplace, it is imperative for the products to communicate the ‘speed’ of the additional features. Thus, it has been hypothesized that adding a few simple changes to the visual representation of a product or the context in which it is being presented could enhance the perception of the product dynamics at a cognitive or emotional level. The present work is aimed at determining the impact of visual elements such as shapes, colors, and textures on the perception of speed. Three hundred and twenty subjects participated in a discrimination task and a reaction task to measure the impact of various patterns, textures, and colors on the perception of speed. Throughout both tasks, the subjects were exposed to a number of various visual patterns or colors presented as a static background or recognizable object for a set amount of time. Based on the subjects’ performance we have identified and quantified the impact of specific visual design patterns and colors on the perception of speed. Primary results indicate promising evidence that certain fundamental visual elements of shape, color, and texture when presented as a static background or object design could induce subtle changes in visual perception that can alter the overall movement dynamics perception.

Oral Movement Similarities between [i] vs. [Λ] Word Articulation and Emotional Expressions Explain the Gleam-Glum Effect

Description
This project investigates the gleam-glum effect, a well-replicated phonetic emotion association in which words with the [i] vowel-sound (as in “gleam”) are judged more emotionally positive than words with the [Ʌ] vowel-sound (as in “glum”). The effect is observed across different modalities and languages and is moderated by mouth movements…

This project investigates the gleam-glum effect, a well-replicated phonetic emotion association in which words with the [i] vowel-sound (as in “gleam”) are judged more emotionally positive than words with the [Ʌ] vowel-sound (as in “glum”). The effect is observed across different modalities and languages and is moderated by mouth movements relevant to word production. This research presents and tests an articulatory explanation for this association in three experiments. Experiment 1 supported the articulatory explanation by comparing recordings of 71 participants completing an emotional recall task and a word read-aloud task, showing that oral movements were more similar between positive emotional expressions and [i] articulation, and negative emotional expressions and [Ʌ] articulation. Experiment 2 partially supported the explanation with 98 YouTube recordings of natural speech. In Experiment 3, 149 participants judged emotions expressed by a speaker during [i] and [Ʌ] articulation. Contradicting the robust phonetic emotion association, participants judged more frequently that the speaker’s [Ʌ] articulatory movements were positive emotional expressions and [i] articulatory movements were negative emotional expressions. This is likely due to other visual emotional cues not related to oral movements and the order of word lists read by the speaker. Findings from the current project overall support an articulatory explanation for the gleam-glum effect, which has major implications for language and communication.
