Visual Attention In Remote Vehicle Supervision: Examining The Effects Of Mental Models And Information Bandwidth, Michael Stanley Politowicz

Psychology Theses & Dissertations

Advances in automation and aviation technologies have been catalysts for the emerging market of Advanced Air Mobility (AAM), an ecosystem of novel aircraft concepts including package delivery drones and passenger carrying air-taxis. Future aircraft operators in this environment will be tasked with remotely supervising multiple highly automated aircraft on a visual interface while receiving less training than traditional pilots. More research should explore how an operator’s potentially limited understanding of an automated system affects visual performance and interactions between human operators and AAM technologies. This study examined the influence of mental models of an autopilot system on visual attention allocation …

Attention And Task Engagement During Automated Driving, James Richard Unverricht

Psychology Theses & Dissertations

Many young drivers suffer fatal crashes each year in the United States at a rate approximately three times greater than more experienced drivers. Automated driving systems may serve to mitigate young drivers high crash rates but remain underexplored in research. This dissertation project examined the effects of levels of automation and interestingness of auditory clips on latent hazard anticipation in young drivers during simulated driving. Participants drove a vehicle at varying levels of vehicle automation (SAE Level 0, 2, or 3) in simulated scenarios, each containing a latent hazard event during which a boring, neutral, or interesting auditory clip was …

The Impact Of First-Person Perspective Text And Images On Drivers’ Comprehension, Learning Judgments, Attitudes, And Intentions Related To Safe Road-Sharing Behaviors, Alexandra Bryson Proaps

Psychology Theses & Dissertations

Drivers and cyclists lack an alignment of road sharing knowledge, attitudes, and expectations, resulting in unnecessary fatalities. Educational countermeasures need to present information that captures drivers’ interest by being personally relevant, facilitate elaboration and synthesis of new information with existing knowledge, and change attitudes, intentions, and behavior. Well-documented health-related communication methods were employed to determine their effectiveness in a transportation domain. Health countermeasure designers use first-person perspective to improve narrative instruction outcomes, based on the Elaboration Likelihood Model (ELM; Petty & Cacioppo, 1986). Exploring narrative perspective-taking as a design tool requires the integration of multiple disciplines.

Our design case stems …

The Effects Of Interruption Relevance And Complexity On Primary Task Resumption And Mental Demand, Brandon Allan Fluegel

Psychology Theses & Dissertations

In the present study, undergraduate students viewed patient charts and entered numerical values from these charts into a medical record database. They were unexpectedly interrupted by secondary tasks that differed in relevance and complexity. The secondary tasks varied by whether they facilitated or inhibited (i.e., relevant or irrelevant) rehearsal of the suspended task and whether they placed a demand on working memory (i.e., high complexity or low complexity). The primary measures of interest were the duration of time needed to resume the primary task and perceived mental demand. The Memory for Goals model (Altmann & Trafton, 2002) predicts that task …

Examining The Effect Of Interruptions At Different Breakpoints And Frequencies Within A Task, Sarah Anastazia Powers

Psychology Theses & Dissertations

Research on the effects of interruptions shows that they can be either costly or beneficial depending on which aspects of an interruption are manipulated. One important aspect that contributes to these conflicting results concerns when an interruption occurs. The present study explored how event segmentation theory (EST) can be used to determine optimal moments for an interruption relying on hierarchical task analysis (HTA) to identify coarse and fine event boundaries. Utilizing a 2 X 3 mixed design, undergraduate students completed a trip planning task divided into three task trials. The within-subjects factor was interruption timing, which had three levels: none, …

The Effect Of Task Interruptions And Reliable Cues On Detection Changes Within Dynamic Scenes, Kimberly N. Perry

Psychology Theses & Dissertations

Interruptions are a common problem for attention and pose a threat to visual task performance. The Memory for Goals (MFG) theory suggests that strongly and accurately encoded cues can assist the ability to resume a primary task after an interruption (Altmann & Trafton, 2002). Encoded cues can undergo an activation decay during an interruption and become forgotten. Currently, there has been limited research on how visual interruptions affect cued recall within a dynamic environment. Thus, the goal of the present study was to examine the effect of cuing and task interruptions on change detection within dynamic scenes. Undergraduate students watched …

The Effects Of Automation Transparency And Reliability On Task Shedding And Operator Trust, William Everett Lehman

Psychology Theses & Dissertations

Because automation use is common in many domains, understanding how to design it to optimize human-automation system performance is vital. Well-calibrated trust ensures good performance when using imperfect automation. Two factors that may jointly affect trust calibration are automation transparency and perceived reliability. Transparency information that explains automated processes and analyses to the operator may help the operator choose appropriate times to shed task control to automation. Because operator trust is positively correlated with automation use, behaviors such as task shedding to automation can indicate the presence of trust. This study used a 2 (reliability; between) × 3 (transparency; within) …

Identifying The Strengths And Weaknesses Of Over-The-Shoulder Attack Resistant Prototypical Graphical Authentication Schemes, Ashley Allison Cain

Psychology Theses & Dissertations

Authentication verifies users’ identities to protect against costly attacks. Graphical authentication schemes utilize pictures as passcodes rather than strings of characters. Pictures have been found to be more memorable than the strings of characters used in alphanumeric passwords. However, graphical passcodes have been criticized for being susceptible to Over-the-Shoulder Attacks (OSA). To overcome this concern, many graphical schemes have been designed to be resistant to OSA. Security to this type of attack is accomplished by grouping targets among distractors, translating the selection of targets elsewhere, disguising targets, and using gaze-based input.

Prototypical examples of graphical schemes that use these strategies …

The Role Of Trust As A Mediator Between System Characteristics And Response Behaviors, Eric T. Chancey

Psychology Theses & Dissertations

There have been several theoretical frameworks that acknowledge trust as a prime mediator between system characteristics and automation reliance. Some researchers have operationally defined trust as the behavior exhibited. Other researchers have suggested that although trust may guide operator response behaviors, trust does not completely determine the behavior and advocate the use of subjective measures of trust. Recently, several studies accounting for temporal precedence failed to confirm that trust mediated the relationship between system characteristics and response behavior. The purpose of the current work was to clarify the roles that trust plays in response behavior when interacting with a signaling …

Effects Of Signal Ambiguity And Signal Location On Target Detection Under Varying Degrees Of Time Constraint, Kimberly E. Culley

Psychology Theses & Dissertations

The purpose of the current study was to investigate the effects of decision-making strategies and tendencies, time constraint, and signal characteristics on decision-making performance utilizing the fuzzy signal detection theory framework. Participants were tasked with deciding whether x-ray images of passenger luggage contained hazardous objects.

The first objective of the study was to develop a methodology for quantifying optimizing versus satisficing tendencies in decision making through direct measurement and observation.

The second objective of the study was to examine how time constraint and specific signal characteristics contribute to decision making. Interestingly, despite having more time available to conduct a comprehensive …

The Effect Of Improvisations And Observations On Standardized Patient Encounters, Subjective Workload And Stress, Elizabeth T. Newlin-Canzone

Psychology Theses & Dissertations

Standardized patients (SPs) are people trained to present a medical case for teaching and assessing medical students and they simultaneously perform several demanding tasks including portraying the patient, assessing the learner, and providing feedback. This study investigated the effect of improvisations and multiple task performance on the ability to observe another's nonverbal (NV) behaviors and rate their communication skills. Subjective reports of mental workload and stress were also obtained. The first study involved undergraduates interviewing for a job. Type of interview (rote and improvisational) and type of observation (passive and active) were manipulated within groups. Based on theories of attention …

Pilot Performance And Eye Movement Activity With Varying Levels Of Display Integration In A Synthetic Vision Cockpit, Julie Michele Stark

Psychology Theses & Dissertations

The primary goal of the present study was to investigate the effects of display integration in a simulated commercial aircraft cockpit equipped with a synthetic vision display. Combinations of display integration level (low/high), display view (synthetic vision view/traditional display), and workload (low/high) were presented to each participant. Sixteen commercial pilots flew multiple approaches under IMC conditions in a moderate fidelity fixed-base part-task simulator. Pilot performance data, visual activity, mental workload, and self-report situation awareness were measured.

Congruent with the Proximity Compatibility Principle, the more integrated display facilitated superior performance on integrative tasks (lateral and vertical path maintenance), whereas a less …
