Publications

The Human Factors Analysis and Classification System (HFACS) is a theoretically based tool for investigating and analyzing human error associated with accidents and incidents. Previous research has shown that HFACS can be reliably used to identify general trends in the human factors associated with military and general aviation accidents. The aim of this study was to extend previous examinations of aviation accidents to include specific aircrew, environmental, supervisory, and organizational factors associated with 14 CFR Part 121 (Air Carrier) and 14 CFR Part 135 (Commuter) accidents using HFACS. The majority of causal factors were attributed to the aircrew and the …

Beneath The Tip Of The Iceberg: A Human Factors Analysis Of General Aviation Accidents In Alaska Versus The Rest Of The United States, Cristy Detwiler, Carla Hackworth, Kali Holcomb, Albert Boquet, Elaine Pfleiderer, Douglas Wiegmann, Scott Shappell

Publications

Historically, general aviation (GA) accidents have been overlooked and their impact under-appreciated when compared with those in the commercial or military sector. Recently however, the Federal Aviation Administration and other governmental and civilian organizations have focused their attention on one piece of this proverbial “iceberg,” that being GA accidents occurring in Alaska. This study examines more than 17,000 GA accidents using the Human Factors Analysis and Classification System. Comparisons of Alaska to the rest of the U.S. (RoUS) included traditional demographic and environmental variables, as well as the human errors committed by aircrews. Overall, categorical differences among unsafe acts (decision …

Why Girls? The Importance Of Developing Gender-Specific Health Promotion Programs For Adolescent Girls, Amanda Birnbaum, Tracy R. Nichols

Department of Public Health Scholarship and Creative Works

Adolescence is a time when many girls begin to develop unhealthy behaviors that can affect myriad short- and long-term health outcomes across their lifespan.2There is evidence that smoking, physical activity, and diet are habituated during adolescence, and some physiologic processes of adolescence, such as peak bone mass development, have direct effects on future health.3-4 Establishing healthy practices, beliefs and knowledge among adolescent girls will decrease morbidity and mortality among adult women and potentially affect the health of men and children through women’s role as healthcare agents. This paper provides a brief review of lifestyle health behaviors among women and girls …

Using Signal Detection Theory To Examine The Effects Of Workload And Likelihood Displays On Human Responses To Alarms, Ernesto A. Bustamante

Psychology Theses & Dissertations

The purpose of this study was to examine the effects of workload and likelihood displays on human responses to alarms through the use of Signal Detection Theory (SDT). Thirty students performed compensatory tracking, resource management, and system monitoring tasks. They interacted with a Binary Alarm System (BAS) or a Likelihood Alarm System (LAS) during varying workload levels. Overall Response Rate (ORR), False Alarm Response Rate (FARR), True Alarm Response Rate (TARR), Sensitivity (d'), and Bias (c), were used as alarm response measures. Root Mean Squared Tracking Error (RMSTE) and Root Mean Squared Resource Management Error (RMSRMF) reflected primary-task performance. Proportion …

Effects Of Background Music On Spatial And Linguistic Processing, Leslie A. Angel, Donald J. Polzella, Greg C. Elvers

Psychology Faculty Publications

Poster session presented at the meeting of the Psychonomic Society. College students were trained according to one of two standardized task protocols: spatial (mental rotation) or linguistic (letter classification).Testing consisted of multiple randomized trials with and without background music (classical piano) at two levels of task difficulty. Raw data for both tasks were response time and accuracy. Background music increased the speed of spatial processing at both difficulty levels, while accuracy of processing remained unaffected. In contrast, background music increased the accuracy of linguistic processing, while speed of processing remained unaffected. These findings, integrated with those of a previous experiment …

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 …

Brighter Noise: Sensory Enhancement Of Perceived Loudness By Concurrent Visual Stimulation, Yoav Arieh, Eric C. Odgaard, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Two experiments investigated the effect of concurrently presented light on the perceived loudness of a low-level burst of white noise. The results suggest two points. First, white noise presented with light tends to be rated as louder than noise presented alone. Second, the enhancement in loudness judgments is resistant to two experimental manipulations: varying the probability that light accompanies sound and shifting from a rating method to a forced choice comparison. Both manipulations were previously shown to eliminate a complementary noise-induced enhancement in ratings of brightness. Whereas noise-induced enhancement of brightness seems to reflect a late-stage decisional process, such as …

Effects Of Familiar Background Music On Working Memory And Motor Tracking, Donald J. Polzella, Scott Schoeling

Psychology Faculty Publications

Poster session presented at the meeting of the Psychonomic Society. Two groups of college students participated as listeners or non-listeners, based on whether or not they preferred background music while working or studying. Both groups were trained according to standardized memory search and unstable motor tracking task protocols. Testing consisted of multiple trials at varying levels of difficulty with and without familiar background music. Background music enhanced motor tracking, particularly when the task was challenging. In contrast, background music disrupted aspects of working memory. There were no differences between listeners and non-listeners. The results suggest that, regardless of an individual’s …

A Human Error Analysis Of General Aviation Controlled Flight Into The Terrain Accidents Occurring Between 1990-1998, Scott A. Shappell, Douglas A. Wiegmann

Publications

Although all aviation accidents are of interest to the Federal Aviation Administration (FAA), perhaps none is more disconcerting than those in which a fully functioning aircraft is inexplicably flown into the ground. Referred to as controlled flight into terrain (CFIT), these accidents continue to be a major safety concern within aviation, in particular general aviation (GA). A previous study as part of the FAA's Safer Skies agenda examined 165 CFIT accidents using root cause analysis and developed 55 interventions to address their causes. While the study represented the work and opinions of several experts in the FAA and industry, the …

The Aggressive Driving Behavior Scale: Developing A Self-Report Measure Of Unsafe Driving Practices, John M. Houston, Paul Harris

Faculty Publications

The purpose of this study was to investigate the reliability and validity of a new 11-item measure of aggressive driving, the Aggressive Driving Behavior Scale, which focuses on behaviors rather than cognitions, emotions, or motivational states. Based on a sample of 200 undergraduates, 111 women and 89 men), the study examined the convergent validity of the new scale with measures of hostility, hypercompetitiveness, and aggressive thoughts and emotions experienced during driving. A principal component analysis of the Aggressive Driving Behavior Scale (alpha = .80) yielded two factors that form reliable subscales labeled Speeding and Conflict Behavior. As expected, the total …

This study examined the relationship between EEG activity and several driving behaviors, as well as differences between day-shift and nightshift workers. Twenty adults, five males and ten females between the ages of 18 and 45, participated in this experiment. Participants included 10 day-shift and 10 night-shift workers. Participants were wired for EEG recording and asked to drive in a 1-hour highway-driving scenario in a driving simulator. Relative powers of alpha, theta and beta were recorded and an EEG index of alertness was …

Stress-Counter Response Training: Flight Simulation Ans Biofeedback, Debra K. Stewart

Psychology Theses & Dissertations

Many attempts to reduce Human Error (HE) in aviation have been applied in the past. However, HE remains the largest reported cause of accidents and incidents in aviation. The present study was designed to implement a novel training method to produce voluntary control over the autonomic nervous system (ANS). Twenty-one participants flew a PC based F-16 flight simulator. There were three conditions: 1. Stress-Counter Response training (SCR), 2, traditional biofeedback training, and 3. A control. It was hypothesized that the SCR training group would show improved physiological control, better flight performance, and lower subjective workload ratings compared to the other …

Judging By Heuristic: Cognitive Illusions In Judicial Decision Making, Chris Guthrie, Jeffrey J. Rachlinski, Andrew J. Wistrich

Vanderbilt Law School Faculty Publications

The institutional legitmacy of the judiciary depends on the quality of the judgments that judges make. Even the most talented and dedicated judges surely make occasional mistakes, but the public expects judges to avoid making systematic errors that favor particular parties or writing opinions that embed these mistakes into the substantive law. Psychological research on human judgment, however, suggests that this expectation might be unrealistic.

How Behavioral Dimensions Interact With Perceived Social Support Dimensions In First Time Expectant Fathers During Their Wives Pregnancy, Rhonda L. Dunder

Theses, Dissertations and Capstones

While changes in women during a pregnancy are apparent, changes in the expectant father are not. However, research has documented the behavioral and attitudinal changes that take place in the soon to be father. The current study investigated which assessment measures of the behavioral dimension, which included anxiety, narcissism, and self-esteem, would correlate with each other to predict a behavior change. Correlations were also measured between variables of the behavioral dimension and perceived social support. Results found a significant positive correlation between self-esteem and narcissism. A significant negative correlation was found between self-esteem and perceived social support. It appears as …

Thirty-four first time expectant fathers age 20 to 38 were individually administered a set of behavior and attitude assessments during the first, second, and third trimesters of their wives pregnancy. This particular study focused on the Love Attitudes Scale. Research indicates that fathers are expected to go through behavior and attitude changes during their wives pregnancy due to several possible reasons like stress, an unhappy marriage, or love development. The main objective of this study was to measure whether or not first time expectant fathers experienced any significant attitude changes during the pregnancy. A second objective was examining if certain …

An Examination Of Individual Differences In Monitoring For Automation Failures, Holly Devries

Psychology Theses & Dissertations

Automation-induced complacency has been documented as a cause or contributing factor in many airplane accidents throughout the last two decades. It is surmised that the condition results when a crew is working in highly reliable automated environments in which they serve as supervisory controllers monitoring system states for occasional automation failures. Although many reports have discussed the dangers of complacency, little empirical research has been produced to substantiate its harmful effects on performance as well as what factors produce complacency. There have been some suggestions, however, that individual characteristics could serve as possible predictors of performance in automated systems.
