Indiana University-Purdue University Indianapolis (IUPUI) / This paper aims to reproduce the voice effect in a pay-for-performance (PFP) environment, ultimately to uncover how affective measures can be leveraged in analyzing the effectiveness of PFP programs. Historically, the effectiveness of PFP programs has been measured by readily available metrics like sales quotas or widgets produced such that effective PFP programs would increase the amount of sales or widgets produced. Using affective measures like pay satisfaction and perceptions of fairness can supplement objective measures in the future. 410 participants with a percentage of their pay involved in PFP participated in this study via MTurk. Employee voice was hypothesized to positively influence perceptions of pay system satisfaction and pay level satisfaction through the mediating effects of procedural (PJ) justice and distributive justice (DJ) respectively. Results yielded significant, positive relationships between voice, PJ, and pay system satisfaction as well as voice, DJ, and pay level satisfaction. Relationships were stronger the more pay the employee had that was variable in the PFP program. These findings suggest that employees are more likely to be satisfied with their pay and the amount of pay in the PFP program as their opportunity to voice their opinions about PFP increase.

Trust is valuable as it plays a vital role in first impressions and decision-making. However, trust perceptions of speakers are heavily influenced by stereotypes and biases. Given how impactful eyewitness testimonies are in courtroom rulings and how often biases are used to judge speakers in courtroom settings, it is crucial to understand what factors impact perceptions of trust within this context. This is the first study to analyze the relationship between trust perception and emotion (Anger, Fear, Happy, Sad, Disgust, and Neutral) within the context of a courtroom testimony while also looking at how race, sex, vocal characteristics of the speaker, and intensity (gun-present vs. gun-absent crime) impact this interaction. Participants listened to a random sample of voices saying, "That is exactly what happened" and then responded yes or no when asked if they trusted the speaker. We found a highly significant interaction between sex and race on the proportion of voices trusted in select emotions. An in-depth analysis of voice characteristics indicated varying effects of pitch, Cepstral Peak Prominence, Vocal tract length, Subharmonic to harmonic ratio, Speech rate, Long-term Average Spectrum, and Harmonics to Noise Ratio (HNR) on perceptions of trust in male and female speakers. This experiment supports findings that heuristic cues influence the perception of trust in the courtroom. Understanding the role stereotypes and biases play in decision-making in the courtroom is vital to ensuring a fair prosecution. / Thesis / Master of Science (MS)

This experiment furthered previous research on perceptions of speakers as a function of various vocal characteristics. A low relevance passage was recorded by male and female speakers, simulating voices of orotund, thin, thoaty, flat, breathy, as well as rate and pitch variations, so as to determine effects on persuasiveness and confidence. Main effects were found regarding gender across all vocal characteristics. While an orotund voice produced predominately positive effects of ratings of speakers' confidence and persuasiveness, a breathy effect elicited negative ratings. The male speaker was judged more harshly than the female speaker when the vocal characterization departed from the norm.

How the Sky Tastes is not simply a collection of stories. It is my representation of moments in life, social commentaries, bits of humor, and pure entertainment all in one. Each story, although unique and easily able to stand alone, shares qualities I find important in writing fiction. First, each story features realistically flawed, yet sympathetic characters dealing with difficulties in life. Secondly, the actual moment is important in each story--whether that moment is something shared between two or more characters or simply the time a certain character comes to a serious realization. Finally, the style can make or break the story. I do not believe in gimmicky writing--form must always have function--but I do feel that the writing must be representative of the characters and the stories that it serves. Experimentation is important in writing. Each story should have its own way of telling itself. All these stories can be seen as experimental in some way, but also all these stories are told the way they have to be told. The characters tell the stories themselves and the writing just follows suit. It is my hope that readers can identify with most, if not all, of these stories, and engage interest in these characters enough to care about what happens to them, even if they don't necessarily like them.
