Self-congruity, Preference, and Pathfinder: An Examination of News Media Outlet Knowledge Structures
Description
Using a modified news media brand personality scale developed by Kim, Baek, and Martin (2010), this study measured the personalities of eight news media outlets and combined them into the same associative network with participants’ self-image via the Pathfinder tool (Schvaneveldt, Durso, & Dearholt, 1989). Using these networks, this study was able to both explore the personality associations of participants and observe if self-congruity, measured by the distance between the self-image node and a brand, is significantly related to participant preference for a brand. Self-congruity was found to be significantly related to preference. However, this relationship was mediated by participants’ fiscal and social orientation. Overall, using Pathfinder to generate associative networks and measure self-congruity could be a useful approach for understanding how people perceive and relate to different news media outlets.

Student pilots are the future of aviation and one of the biggest problems that they face as new pilots is fatigue. The survey was sent out asking if student pilots were fatigued, if they attribute flight training, school work, work outside of school, and social obligations to their sleep loss, and how they spend their time on those activities. The survey was given to aviation students at Arizona State University (ASU) Polytechnic Campus. ASU student pilots were found to be fatigued through a single sample t-test. Other t-tests were done on each of the questions that asked student pilots how flight training, school work, work outside of school and social obligations affect their sleep loss. Flight training and school were found to be contributing to student pilots sleep loss. Work outside of school and social obligations were found to not be contributing to student pilots sleep loss. It was found that student pilots’ tendency to use a planner or calendar was found to not be significant. Along with this planning through the week when they will do assignments or study for exams was also not found to be significant. Students making lists of assignments and when they are due was also found to not be significant. The t-test also found that student pilots are neutral on the topic of whether good time management skills would help increase the amount of sleep that they get.

Highly automated vehicles require drivers to remain aware enough to takeover
during critical events. Driver distraction is a key factor that prevents drivers from reacting
adequately, and thus there is need for an alert to help drivers regain situational awareness
and be able to act quickly and successfully should a critical event arise. This study
examines two aspects of alerts that could help facilitate driver takeover: mode (auditory
and tactile) and direction (towards and away). Auditory alerts appear to be somewhat
more effective than tactile alerts, though both modes produce significantly faster reaction
times than no alert. Alerts moving towards the driver also appear to be more effective
than alerts moving away from the driver. Future research should examine how
multimodal alerts differ from single mode, and see if higher fidelity alerts influence
takeover times.

We experience spatial separation and temporal asynchrony between visual and
haptic information in many virtual-reality, augmented-reality, or teleoperation systems.
Three studies were conducted to examine the spatial and temporal characteristic of
multisensory integration. Participants interacted with virtual springs using both visual and
haptic senses, and their perception of stiffness and ability to differentiate stiffness were
measured. The results revealed that a constant visual delay increased the perceived stiffness,
while a variable visual delay made participants depend more on the haptic sensations in
stiffness perception. We also found that participants judged stiffness stiffer when they
interact with virtual springs at faster speeds, and interaction speed was positively correlated
with stiffness overestimation. In addition, it has been found that participants could learn an
association between visual and haptic inputs despite the fact that they were spatially
separated, resulting in the improvement of typing performance. These results show the
limitations of Maximum-Likelihood Estimation model, suggesting that a Bayesian
inference model should be used.

Description
In baseball, the difference between a win and loss can come down to a single call, such as when an umpire judges force outs at first base by typically comparing competing auditory and visual inputs of the ball-mitt sound and the foot-on-base sight. Yet, because the speed of sound in air only travels about 1100 feet per second, fans observing from several hundred feet away will receive auditory cues that are delayed a significant portion of a second, and thus conceivably could systematically differ in judgments compared to the nearby umpire. The current research examines two questions. 1. How reliably and with what biases do observers judge the order of visual versus auditory events? 2. Do observers making such order judgments from far away systematically compensate for delays due to the slow speed of sound? It is hypothesized that if any temporal bias occurs it is in the direction consistent with observers not accounting for the sound delay, such that increasing viewing distance will increase the bias to assume the sound occurred later. It was found that nearby observers are relatively accurate at judging if a sound occurred before or after a simple visual event (a flash), but exhibit a systematic bias to favor visual stimuli occurring first (by about 30 msec). In contrast, distant observers did not compensate for the delay of the speed of sound such that they systematically favored the visual cue occurring earlier as a function of viewing distance. When observers judged simple visual stimuli in motion relative to the same sound burst, the distance effect occurred as a function of the visual clarity of the ball arriving. In the baseball setting, using a large screen projection of baserunner, a diminished distance effect occurred due to the additional visual cues. In summary, observers generally do not account for the delay of sound due to distance.

The Phoenix area, is known for suburban sprawl which did not happen in isolation but was the result of many external factors. It was not just large environmental and cultural factors that changed over time, but the actual physical characteristics of sprawl that have changed from community to community over the decades. Characteristics like physical size of houses and lot size, along with changes in the residential and commercial design and building style have changed from around the 1950s to present day, with homes being larger and covering more of each parcel. These characteristics were analyzed in 21 communities in the Phoenix area that were built from 1950 to 2019 to find how these characteristics have changed over time. While the issue of sprawl will never fully go away, by learning what the characteristics are that make up the definition of sprawl, stakeholders like cities, planners, and developers will have better knowledge for planning for tomorrow.

With the growth of autonomous vehicles’ prevalence, it is important to understand the relationship between autonomous vehicles and the other drivers around them. More specifically, how does one’s knowledge about autonomous vehicles (AV) affect positive and negative affect towards driving in their presence? Furthermore, how does trust of autonomous vehicles correlate with those emotions? These questions were addressed by conducting a survey to measure participant’s positive affect, negative affect, and trust when driving in the presence of autonomous vehicles. Participants’ were issued a pretest measuring existing knowledge of autonomous vehicles, followed by measures of affect and trust. After completing this pre-test portion of the study, participants were given information about how autonomous vehicles work, and were then presented with a posttest identical to the pretest. The educational intervention had no effect on positive or negative affect, though there was a positive relationship between positive affect and trust and a negative relationship between negative affect and trust. These findings will be used to inform future research endeavors researching trust and autonomous vehicles using a test bed developed at Arizona State University. This test bed allows for researchers to examine the behavior of multiple participants at the same time and include autonomous vehicles in studies.

Description
The study at hand investigated the effects of guidance and type of occlusion on the prediction of shot direction during a soccer penalty kick. Seventy participants took an online survey where they had to guess the direction of a penalty kick from the perspective of a goalkeeper. Half the participants were placed in a group where they had access to tips on what to look for, while the other group had no tips provided. Participants were shown videos in which the penalty shooter had their upper body covered or their lower body covered. Participants had 30 seconds to decide what side the ball was going to, right or left. Results showed that there is no significant between the two groups in terms of judgment accuracy. The group that received no guidance and had the kicker's lower body covered was the group with the highest average score, 50.44%. The findings may help future studies that focus on what material is taught to goalkeepers in a classroom setting and the role of occlusion during free kicks outside the 18-yard box.

Description
The Barrett Honors College website contains a lot of information that isn’t easily accessible by Honors Students. Many honors students have trouble finding the correct information they need. Important information is scattered all over the website making it difficult for honors students to find and understand the information they need. One example of this is the requirements for Lower and Upper Division credit. This website displays the upper and lower division credit needed for a student to graduate from the honors college via a noninteractive flowchart. Many high school seniors find it difficult to understand the mundane flowchart outlining the required honors credit that is required for graduating from Barrett at Arizona State University. Also, it is confusing for many transfer students with unique circumstances to determine the necessary requirements for them to graduate as a Barrett student.
These difficult flowcharts and confusing websites have a huge impact on a student’s ability to adequately receive the information they need and, in the end, can have a negative impact on their ultimate decision when deciding if Barrett is right for them. A better user experience can be a more effective way of displaying information to students. A better design that allows to user more interaction would allow for the user to better understand the information they are presented. Instead of a monotone flowchart displaying the requirements necessary to graduate with honors status, A web application where a user can input their information and get an output of the necessary requirements tailored to the unique circumstance would be more informative, useful, and easier to use. The web app would take information such as a student’s year, whether it be an incoming freshman or transfer student, and their current and previous course credit to determine the specific number of honors credits, The Human Event courses, and Thesis project required for this user to complete the requirements for Barrett Honors College. This application would give the user a better understanding of what is required of them and in turn lead to a better user experience.

During the height of COVID-19 in the summer of 2020, most major sports leagues were shut down or postponed, to limit the spread of COVID-19. However, people still yearned for the community of cheering on their favorite team. To that end, The Game Band, a Los Angeles-based game development studio, decided to make America's favorite pastime, baseball, virtual. Just like that, Blaseball was born. In this creative project, the Season Twelve version of Blaseball.com was subjected to analysis of its user interface and user experience elements by the author of this paper in the role of the researcher. The research questions posited by this project were as follows: - What user interface/user experience elements of the Season Twelve version of Blaseball.com were effective, and what elements detracted from the purpose of the site? - What recommendations could be made by the researcher to improve the user experience and allow for a more effective user experience of the Season Twelve version of Blaseball.com? To answer these questions, two deliverables were decided upon. The first was a research study consisting of a usability survey and interviews with web developers who worked on Blaseball or Blaseball-related projects. The second deliverable was an industry-level analysis of the Season Twelve version of Blaseball.com to be presented as a culmination of the research and work. Through this process, it had been discovered that while the site was simplistic and could easily direct users to other pages, as intended by the developers, UI elements on individual pages confused and misled users. As such, clarifications and a more in-depth UI were recommended.
