Description
Multimedia learning has become increasingly popular as it proceeds to understand how different senses such as the visual and auditory systems work together to present information. The aim of the present study was to examine the effect of temporal contiguity, a principle of multimedia learning, while displaying images and narration of fruits and vegetables to increase memorization of content. 21 preschool students between the ages of 4 and 5 from Arizona State University’s Child Study Lab were recruited for the purpose of the study. Students received one of two versions of a short video while inside the classroom. The two videos displayed information either at the same time or successively. Children’s knowledge was assessed with a drag and drop categorization game. The findings show there were no significant differences between the two conditions. Future studies should consider a longer training period when developing multimedia learning technology to ensure content is retained.

Description
Previous research has shown that perceptual illusions can enhance golf putting performance, and the effect has been explained as being due to enhanced expectancies. The present study was designed to further understand this effect by measuring putting in 3 additional variations to the Ebbinghaus illusion and by measuring putting kinematics. Nineteen ASU students with minimal golf experience putted to the following illusion conditions: a target, a target surrounded by small circles, a target surrounded by large circles, a target surrounded by both large and small circles, no target surrounded by small circles and no target surrounded by large circles. Neither perceived target size nor putting error was significantly affected by the illusion conditions. Time to peak speed was found to be significantly greater for the two conditions with no target, and lowest for the condition with the target by itself. Suggestions for future research include having split groups with and without perceived performance feedback as well as general performance feedback. The size conditions utilized within this study should continue to be explored as more consistent data could be collected within groups.

Description
Civilian and military use of remotely piloted aircraft (RPA) has significantly increased in recent years. Specifically, the United States Air Force (USAF) has an insatiable demand for RPA operations, that are responsible for fulfilling critical demands in every theater 24 hours a day, 365 days a year (United States Air Force, 2015). Around the clock operations have led to a manning shortage of RPA pilots in the USAF. The USAF MQ-9 “Reaper” Weapons School trains tactical experts and leaders of Airmen skilled in the art of integrated battle-space dominance (United States Air Force, 2015). Weapons Officers for the MQ-9 platform are also critically under-manned, with only 17% of allocated slots filled (B. Callahan, personal communication, January 28, 2016). Furthermore, the leading cause of training attrition has been attributed to lack of critical thinking and problem solving skills (B. Callahan, personal communication, January 28, 2016); skills not directly screened for prior to entering the RPA pilot career field. The proposed study seeks to discover patterns of student behaviors in the brief and debrief process in Weapons School, with the goal of identifying the competencies that distinguish the top students in Weapons School.

Description
Visual aides, such as PowerPoint slides, hand-outs, and lecture notes on whiteboards, are often used in classrooms to convey important content to learners, especially in high school and college. When using these visual learning aides, it is important to consider which qualities of these presentations can affect learning— positively or negatively—and how those qualities interact with individual student characteristics. In the present study, we examine the overlap between audio and text and how the effects of overlap potentially interact with reading comprehension abilities. The examination of these potential influences on learning in this study is inspired by Cognitive Load Theory, the Dual-Channel Assumption, and prior research.

Description
Cyber operations are a complex sociotechnical system where humans and computers are operating in an environments in constant flux, as new technology and procedures are applied. Once inside the network, establishing a foothold, or beachhead, malicious actors can collect sensitive information, scan targets, and execute an attack.Increasing defensive capabilities through cyber deception shows great promise by providing an opportunity to delay and disrupt an attacker once network perimeter security has already been breached. Traditional Human Factors research and methods are designed to mitigate human limitations (e.g., mental, physical) to improve performance. These methods can also be used combatively to upend performance. Oppositional Human Factors (OHF), seek to strategically capitalize on cognitive limitations by eliciting decision-making errors and poor usability. Deceptive tactics to elicit decision-making biases might infiltrate attacker processes with uncertainty and make the overall attack economics unfavorable and cause an adversary to make mistakes and waste resources.
Two online experimental platforms were developed to test the Sunk Cost Fallacy in an interactive, gamified, and abstracted version of cyber attacker activities. This work presents the results of the Cypher platform. Offering a novel approach to understand decision-making and the Sunk Cost Fallacy influenced by factors of uncertainty, project completion and difficulty on progress decisions. Results demonstrate these methods are effective in delaying attacker forward progress, while further research is needed to fully understand the context in which decision-making limitations do and do not occur. The second platform, Attack Surface, is described. Limitations and lessons learned are presented for future work.

Description
The bilingual experience is an often-studied multivariate phenomenon with a heterogeneous population that is often described using subtypes of bilingualism. “Bilingualism” as well as its subtypes lack consistent definitions and often share overlapping features, requiring researchers to measure a number of aspects of the bilingual experience. Different variables have been operationalized to quantify the language proficiencies, use, and histories of bilinguals, but the combination of these variables and their contributions to these subtypes often vary between studies on bilingualism. Research supports that these variables have an influence not only on bilingual classification, but also on non-linguistic outcomes including perceptions of self-worth and bicultural identification. To date, there is a lack of research comparing the quantification of these bilingual subtypes and these non-linguistic outcomes, despite research supporting the need to address both. Person-centered approaches such as latent profile analysis (LPA) and fuzzy set qualitative comparative analysis (fsQCA) have been applied to describe other multivariate constructs with heterogeneous populations, but these applications have yet to be used with bilingualism. The present study integrates models of bilingualism with these analytic methods in order to quantitatively identify latent profiles of bilinguals, describe the sets of conditions that define these subtypes, and to characterize the subjective experiences that differentiate these subtypes. The first study uses an existing data set of participants who completed the Language and Social Background Questionnaire (LSBQ) and performs LPA and fsQCA, identifying latent profiles and the sets of conditions that these subtypes. The following studies use a second set of bilinguals who also completed the LSBQ as well as a supplementary questionnaire, characterizing their identification with biculturalism and their feelings of self-worth. The analyses are repeated with these data to describe the profiles within these data and the subjective experiences in common. Finally, all analyses are repeated with the combined datasets to develop a final model of bilingual subtypes, describing the differences in language use and history within each subtype. Results demonstrate that latent models can be used to consistently characterize bilingual subtypes, while also providing additional information about the relationship between individual bilingual history and attitudes towards cultural identification.

Description
The relationship between user experience, learning, and psychology is complex. There are many rules and concepts that guide experience design. It is likely that some of the guidance is valid whereas other guidance is not. This explores some of that guidance and evaluates how they are linked to learning. Do the guidance’s made 25, 50, 100 years ago still hold true today? Additionally, the psychological background behind the way someone holds memory is important. Knowing how information is stored and processed helps educators provide the best learning experience possible. With an eye toward perception and cognition, this paper examines the relevance of the various pieces of guidance. The results suggest that, overall, this guidance is still valid and valuable to current learning trends and designs. This suggests that user experience designers for education need to pay attention to the guidance provided by psychology when designing learning management systems, placing content in a course, and choosing which aesthetics to follow.

Description
ASU’s Software Engineering (SER) program adequately prepares students for what happens after they become a developer, but there is no standard for preparing students to secure a job post-graduation in the first place. This project creates and executes a supplemental curriculum to prepare students for the technical interview process. The trial run of the curriculum was received positively by study participants, who experienced an increase in confidence over the duration of the workshop.
