Ecological Interface Design For Flexible Manufacturing Systems: An Empirical Assessment Of Direct Perception And Direct Manipulation In The Interface, Dylan G. Cravens

Browse all Theses and Dissertations

Four interfaces were developed to factorially apply two principles of ecological interface design (EID; direct perception and direct manipulation) to a flexible manufacturing system (FMS). The theoretical foundation and concepts employed during their development, with findings related to more significant issues regarding interface design for complex socio-technical systems, are discussed. Key aspects of cognitive systems engineering (CSE) and EID are also discussed. An FMS synthetic task environment was developed, and an experiment was conducted to evaluate real-time decision support during supervisory operations. Participants used all four interfaces to supervise and maintain daily part production at systematically varied levels of difficulty …

Mortality Salience And The Effects Of Autonomy On Death Anxiety, Dylan Earlin Horner

ETD Archive

The present research built on prior work suggesting that mortality salience (MS) can undermine psychological well-being and explored the previously-untested hypothesis that autonomy can mitigate that effect. Specifically, the study investigated the effects of primed autonomy on measured death anxiety following a reminder of mortality. Participants (n = 119) were randomly assigned to either an MS or control condition and then, following a delay, were primed with the concept of either autonomy or being controlled. Death anxiety was then measured. Results found that MS increased death anxiety among those in the controlled prime condition, but not among those in the …

The Effects Of Mortality Salience And Autonomy Priming On Worldview Defensiveness, Joseph P. Conti

ETD Archive

Terror Management Theory posits that people are motivated to defend against death awareness by maintaining cultural beliefs and behaviors that transcend mortality— sometimes motivating hostile, even militaristic, defenses of one’s culture. In contrast, self-determination theory suggests that autonomous regulation (self-determination) serves as a platform for personal growth and well-being. However, the present thesis suggests that, in addition to fueling growth, self-determination may also help buffer against the awareness of mortality, thus mitigating the impact of death awareness on hostile cultural worldview defense. To test this hypothesis, American participants were randomly assigned to be reminded of mortality or a control topic, …

Spatialized Auditory And Vibrotactile Cueing For Dynamic Three-Dimensional Visual Search, Rachel J. Cunio

Browse all Theses and Dissertations

The traditional method of maintaining spatial awareness through visual displays can cause visual system overload and lead to performance decrements. This study examined the benefits of spatialized auditory, tactile, and audio-tactile cues for maintaining awareness as a method of enhancing visual search performance. I examined visual search performance in an immersive, dynamic, three-dimensional (360-degree), virtual reality environment with no cues, spatialized auditory cues, degraded spatialized auditory cues, spatialized tactile cues, spatialized audio-tactile cues, and degraded spatialized auditory with tactile cues. Results indicated a significant reduction in visual search time from the no-cue condition when any cues were presented. The tactile …

Atheism And The Effects Of Mortality Salience And Limited Analytic Processing Ability On Religious Faith And Teleological Thinkin, Brett Jordan Waggoner

ETD Archive

The scenario of the atheist in the proverbial foxhole has been a topic of discussion in religious circles for centuries. Building on prior research utilizing terror management theory (TMT), a dual process model of cognition, and previous work suggesting that humans are intuitively wired for teleological and religious concepts, the researchers set out to examine atheist’s religiosity when confronted with the reality of one’s impermanence. To explore this idea, the present experiment recruited a sample of atheists, manipulated their awareness of mortality, manipulated their ability to employ analytic thinking, and measured various intuitive cognitions (e.g., teleological reasoning) alongside religious belief. …

The Relationship Between Social Status Motivation And The Detection Of Trustworthy And Affiliative Cues In Faces, Christopher J. Lustgraaf

Dissertations

A prominent feature of human (and non-human primate) social group structure involves the establishment and maintenance of a social hierarchy; that is, social groups are arranged hierarchically, based on individuals’ level of status, and conspecifics who more effectively ascend this status hierarchy accrue more reproductive and resource benefits (Hawley, 1999). Thus, for any individual, other group members could be either a threat to one’s status, or an ally to assist status goals, and accurate identification of these various social targets would have adaptive utility in status maintenance or status hierarchy ascension. The current study tested the hypotheses that activation of …

Variability And Location Of Movement Endpoint Distributions: The Influence Of Instructions For Movement Speed And Accuracy, Abhishek Dey

ETD Archive

An influential theory of motor control predicts that targeted hand movements should be aimed at the target center and that the variability of movement endpoint distributions should fill the target region (Meyer et al., 1988). Because increases in the amount of movement endpoint variability correlates with increases in movement speed (Schmidt et al., 1979), centering the distribution on the target center and expanding variability to the limits of the target boundaries should allow for maximization of movement speed, without the production of movement errors (i.e., target misses). Slifkin and Eder (2016) recently found that those predictions only held over a …

Aging And Emotion Recognition: An Examination Of Stimulus And Attentional Mechanisms, Stephanie Nicole Sedall

ETD Archive

Emotion recognition is essential for interpersonal communication. However, previous research has suggested that older adults are not as accurate as younger adults in recognizing certain emotions, particularly negative facial expressions of anger, fear, and sadness. Including additional contextual information (e.g., manipulation of certain facial features) might help us better understand these age differences. The present study investigated how potential age differences in emotion recognition are influenced by stimulus factors (target eye gaze direction) as well as facial viewing patterns, cognitive functioning, and physiological processes. A sample of younger and older adults viewed static facial expressions depicting anger, fear, sadness, happiness, …

An Experimental Test Of Whether Mortality Salience Can Motivate Open-Mindedness Among Individuals With Intrinsic Goal Orientations, Mark Blades

ETD Archive

Terror management theory posits that when people are primed with thoughts of death, they will seek to abide by their cultural worldview beliefs. For example, mortality reminders motivate those with an extrinsic goal orientation to strive to accomplish culturally valued goals (e.g., wealth) and defend familiar cultural worldviews. But, as of yet, no research has investigated the possibility that MS might motivate those with an intrinsic goal orientation to strive instead to explore culturally, socially, or intellectually novel experiences and information. The present research hypothesized that MS would lead individuals with stronger extrinsic goal orientations to defensively prefer their familiar …

The Role Of Attention In Retrieval Practice, Joshua W. Whiffen

Open Access Theses

Dividing attention during encoding is detrimental to learning. In contrast, dividing attention during retrieval appears to have very little effect on recall. However, very few studies have investigated whether dividing attention during initial recall has an impact on subsequent retrieval attempts. ^ Research on retrieval practice has clearly shown that retrieval is an active process that leads to important changes in memory that ultimately enhance long term retention. However, it has yet to be established exactly how retrieval practice derives its benefits. One possibility is that retrieval involves the reinstatement of temporal context, which leads to the updating or encoding …

Cued Visual Search And Multisensory Enhancement, Jordan Haggit

Browse all Theses and Dissertations

Previous research has been divided on whether or not multisensory cues can speed visual search relative to their component unisensory cues alone. Some studies (e.g., Mateo et al., 2012) found reaction times for multisensory cues were not faster than the RT of the faster component unisensory cue alone. Other studies (e.g., Oskarsson et al., 2012) found the multisensory cue to be faster than either unisensory cue alone (i.e., multisensory enhancement). This study aimed to determine whether the relative effectiveness match between auditory and tactile cues affects multisensory enhancement on a visual search task. In Experiment 1 we estimated for each …

The Effects Of Implementation Intentions On Volunteer Firefighter Exercise Behavior: A Randomized Controlled Study, Rodney L. Hammer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The current study used a randomized control design to determine if an implementation intention intervention based on the Health Action Process Approach would increase exercise behavior in volunteer firefighters. One hundred forty-seven male and female volunteer firefighters from nine fire departments participated. The treatment group received a survey that prompted them to create exercise implementation intentions by describing "where," "when," and "how" they will exercise, while the control group survey included a general exercise message.

We hypothesized that the implementation intervention would increase exercise behavior while the general exercise message would have no effects on exercise, that earlier stage-of-change exercisers …

Walter Miles And His 1920 Grand Tour Of European Physiology And Psychology Laboratories: A Reproduction Of The Original Typescript, Walter R. Miles, C. James Goodwin, Lizette Royer Barton

University of Akron Press Publications

Walter R. Miles (1885-1978) was an American experimental psychologist very much interested in laboratory apparatus and procedures and their applications to human behavior. Early in his career, Miles received an appointment as a research scientist at the Carnegie Nutrition Laboratory in Boston, Massachusetts. When Miles arrived at the Carnegie Nutrition Laboratory in 1914, work was well underway on the physiological effects of various nutrients on the human body. Miles began studies on the effects of alcohol on physiological and psychological functioning.

The First World War severed many of the relationships that the Carnegie Laboratory had with research counterparts in Europe. …

Threat Perception As A Determinant Of Pro-Environmental Behaviors: Public Involvement In Air Pollution Abatement In Cache Valley, Utah, Joshua D. Marquit

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Threat perception related to environmental issues such as air pollution may be a determinant of pro-environmental behaviors. Among the potential threats of air pollution, include the perceived impacts on the psychological, social, and economic wellbeing of a community. Because of rapid increases in population growth, urbanization, and the mountainous landscapes, the American West is extremely susceptible to the adverse impacts of air pollution.

A secondary data analysis was conducted using data from the Air Quality Perception Survey conducted in Cache County, Utah. The survey focused on the public perception of air pollution in Cache County and perceived impact on personal …

Preference, Resistance To Change, And Qualitatively Different Reinforcers, Christopher Aaron Podlesnik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Preference for one stimulus context over another and resistance to disruption within those contexts are a function of the conditions of reinforcement arranged within those contexts. According to behavioral momentum theory, these measures are converging expressions of the concept of response strength. Most studies have found that preference in concurrent chains and resistance to change are greater in contexts presenting higher rates or larger magnitudes of reinforcement. The present series of experiments attempted to extend behavioral momentum theory by examining whether differences in reinforcer type affect relative response strength with rats lever pressing for different types of food. In Experiment …

Language In Social Contexts: An Examination Of The Effects Of The Linguistic Intergroup Bias On Social Categorization And Interpersonal Behavior, Virginia Ann Cylke

Electronic Theses and Dissertations

This dissertation examines the role of language in social contexts. Specifically, two experiments were designed to extend our understanding of the Linguistic Intergroup Bias (LIB) by elucidating its effects on stereotype application and social behavior. The LIB is the tendency to describe positive in-group and negative out-group behaviors more abstractly than negative in-group and positive out-group behaviors. The first experiment examined the extent to which the LIB augments intergroup categories and perpetuates stereotype use. When asked to match positive and negative behavioral descriptions written at different levels of abstraction to in-group and out-group faces, participants tended to categorize abstract negative …
