Subjective Measures Of Implicit Categorization Learning, Audrey Zlatkin

Electronic Theses and Dissertations

The neuropsychological theory known as COVIS (COmpetition between Verbal and Implicit Systems) postulates that distinct brain systems compete during category learning. The explicit system involves conscious hypothesis testing about verbalizable rules, while the implicit system relies on procedural learning of rules that are difficult to verbalize. Specifically from a behavioral approach, COVIS has been supported through demonstrating empirical dissociations between explicit and implicit learning tasks. The current studies were designed to gain deeper understanding of implicit category learning through the implementation of a subjective measure of awareness, Meta d', which until now has not been validated within a COVIS framework. …

The Art Of Caring: Increasing Empathy Through Conversation, Joy Harlynking

Postures In Mobile Device Usage: Effects On Interpretation Bias, Mood, And Physical Tension, Gabriela Flores-Cruz

Honors Undergraduate Theses

Past research has shown that there is a relationship between body posture and cognitive processes. However, postures used with technological devices has not been studied more extensively. The purpose of this study was to examine posture effects when using a mobile device on interpretation bias, mood, and physical tension. Each participant was randomly assigned one of three conditions: sitting slumped, sitting upright, or lying down. Participants were asked to complete the Scrambled Sentences Task (SST), a task of unscrambling emotional and neutral sentences, to measure their interpretation bias. Additional questions were asked to measure the participant's physical tension and mood. …

Aviation Weather Products In General Aviation: Interpretability And Usability Research Trends, Jacqueline Mcsorley, Jayde King, Beth Blickensderfer

General Aviation Weather Display Interpretation

As a result of advances in weather forecasting and technology, today’s General Aviation (GA) pilots have access to a wealth of aviation weather information. During pre-flight planning, GA pilots may access weather radar images, satellite pictures, winds, and forecast maps. During flight, pilots can access in-cockpit weather displays, as well as, handheld portable weather devices. Despite the increasing advancement and accessibility of weather displays, there is limited research addressing the interpretability of both in-cockpit and preflight weather displays. This is particularly concerning considering that preflight planning and poor product interpretability have been cited as possible contributing factors for GA weather …

Honors Undergraduate Theses

The present study empirically examined the effects of four fatiguing task domains on executive function through participants' reaction time, accuracy, and brain activity in prefrontal cortex (PFC). Forty college-age participants were collected (16 males and 24 females), of which eleven were examined using a functional near-infrared spectroscopy (fNIRS) imaging system. The present study used a 4×2 mixed factorial design consisting of fatiguing task (arm contractions task, vigilance task, distance-manipulated Fitts' task, size-manipulated Fitts' task) as a between-participant variable and n-back testing period (pre-test versus post-test 3-back task) as a within-participant variable. Results indicated significant increases in 3-back performance after …

Difference In Attitudes Toward Crew Resource Management Based On Nationality, Christoph Zurman, Herbert O. Hoffmann, Hans-Joachim K. Ruff-Stahl

International Journal of Aviation, Aeronautics, and Aerospace

The E-3A Airborne Early Warning and Control System aircraft operates with multinational crewmembers from 15 different nations on 12 different aircrew positions. Given this non-standard cultural environment, the authors explored the differences in the attitude toward Crew Resource Management (CRM), based on nationality, and how these differences could be used as a predictor for other nationalities attitudes. The potential benefit of this study may be, that CRM methods could be developed further to either work universally, independent to national or cultural backgrounds, or be adjusted for different cultural contexts in order to be even more effective. Primary data was gathered …

The Effects Of Presence And Cognitive Load On Episodic Memory In Virtual Environments, Paul Barclay

Electronic Theses and Dissertations

Episodic memory refers to an individual's memory for events that they have experienced in the past along with the associated contextual details. In order to more closely reflect the way that episodic memory functions in the real world, researchers and clinicians test episodic memory using virtual environments. However, these virtual environments introduce new interfaces and task demands that are not present in traditional methodologies. This dissertation investigates these environments through the lenses of Presence and Cognitive Load theories in order to unravel the ways that basic technological and task differences may affect memory performance. Participants completed a virtual task under …
