Music Density: A Novel Measurement Of Music Perception, Tyler Ussery

All Master's Theses

Empirical research in fields such as music perception, cognition, and therapy has developed considerably in recent decades. While many studies implement musical stimuli, there are few expeditious metrics for identifying the objective characteristics of music itself. The current study proposed and developed a tool for measuring perception of the theoretical concept of music density. Music density can be defined as the compactness of auditory information that comprises a piece of music. For this study, five musical factors were explored (tempo, texture, timbre, dynamics, and predictability) via a 5-point Likert scale. It is well established that personality is an important …

Cannabis Cues And Effects On Social Anxiety, Erica Steinberg

All Master's Theses

Prior research has shown that individuals experiencing social anxiety may use cannabis for self-medication; therefore, the current study evaluated if viewing cannabis cues would reduce feelings of social anxiety. Central Washington University undergraduates enrolled in psychology courses (n = 124; 66.7% female; M_age = 19.8, SD_age = 4.7) were shown cannabis cues after viewing expressive facial images that prior research has shown induces feelings of social anxiety. Contrary to prior research, the current study found that emotional faces did not significantly affect state-trait anxiety as measured by the 6-item State-Trait Anxiety Inventory (STAI-6) but that trait social …

Critically Evaluating Website Credibility: Factors That Influence Perceptions Of Online Mental Health Information, Mikayla Kimery

All Master's Theses

Research on the use of online information has suggested that general users of the internet do not critically evaluate the information they consume. In addition, specific elements of online information, such as the presence of advertisements, has been shown to affect perceptions of that information, resulting in less favorable ratings of websites. In contrast, communication studies have shown that perceptions of the presented information increased favorably when an image of a brain was included even when the actual information was considered insufficient in quality by experts. To date, the combined effects of brain images and advertisements on evaluations of online …

Mood Effects And Individual Differences On Reappraisal And Distraction: An Erp Study Of The Sensitivity Of Emotion Regulation Strategies, Elsa Mastico

All Master's Theses

The present research evaluated the effect of mood and individual differences on the regulatory process of emotions by using a regulation task with negative and neutral images to assess reappraisal and distraction ability. Specifically, this research evaluated the average amplitude of the latent positive potential (latent positivity, LPP) brainwave linked to distraction and reappraisal using an ERP analysis. In addition, the current study compared the modulation of the LPP to the self-reported mood of the participants and their individual differences in regulation ability through scores of a self-report emotion regulation questionnaire. The latent positive potentials from an emotion regulation task …

Examining Environmental Use By Captive Lemur Catta And Varecia Rubra, Rhiannon Belcher

All Master's Theses

There are over 100 named species of lemurs, of which 94% are considered threatened with extinction by the International Union for the Conservation of Nature (IUCN). They live in increasingly fragmented forests. To understand how best to protect them in their natural habitats, we can observe how they manipulate the environment and how they use objects, both natural and humanmade, around them. Understanding their behavior is a critical component of conservation, and observing behavior in a captive setting allows us to study lemur-environment relationships without disrupting what little habitat is left in Madagascar. In this study I investigated whether the …

Forgive Them, Forgive Them Not: The Role Of Remorse And Empathy In Interpersonal Forgiveness, Molly Mortensen

All Master's Theses

Forgiveness research has suggested that the reduction of negative thoughts and emotions between a victim and perceived transgressor (forgiveness) may be beneficial for close, personal relationships. The current study aimed to examine the influence of perceived remorse and elicited empathy on forgiveness following the occurrence of a hypothetical transgression. It was hypothesized that (a) participants would demonstrate the greatest levels of Forgiveness in the condition of Remorse and Empathy compared to all other conditions, (b) Empathy would increase Forgiveness only when combined with Remorse, and (c) Remorse would be more critically to increasing Forgiveness than Empathy. Participants from Central Washington …

A Book And Its Cover: The Effects Of Dynamic And Static Facial Expressions On The Perction Of Personality Traits, Jonathan Ojeda

All Master's Theses

This study used three dynamic and three static images of older adult men depicting either smiling, scowling, or neutral facial expressions to examine the influence of motion on emotion identification and stereotype activation, specifically the Halo Effect, in older adults (55-85 years). To that end, two hypotheses emerged: 1) older adults will be more accurate in identifying facial expressions when viewing dynamic facial expressions than static facial expressions, and 2) participants exposed to the dynamic stimuli would experience greater levels of the Halo Effect with the greatest levels in the smiling facial expression condition. A 2 (stimulus type: dynamic and …

The Effects Of Feedback Sequence On Cognitive Performance, Travis W. Pyle

All Master's Theses

The current study tested the effects of feedback sequence on performance on a visual-spatial task. Twenty-three female participants were randomly assigned to one of five feedback sequence conditions which occurred after two consecutive trials of a hole-punch task. The five feedback sequence conditions consisted of positive-positive (i.e., positive feedback followed by positive feedback), positive-negative, negative-positive, negative-negative, and a no-feedback control group. Positive feedback was presented as a 80%-90% accuracy range whereas negative feedback was a 30%-40% accuracy range. Third trial accuracy and completion time were measured as was locus of control via the Internal Control Index (ICI) survey. Analyses revealed …

Javan Gibbon (Hylobates Moloch) Non-Vocal Social Communication And Gesture Use With Conspecifics, Melanie Bell

All Master's Theses

I explored gestures used by captive Javan gibbons (Hylobates moloch) at the Gibbon Conservation Center (Santa Clarita, CA). I hypothesized that a sender gibbon’s gesture modality would vary with the recipient gibbon’s attentional state and the sender would be equally likely to use all modalities (tactile, visual, actions, and facial expressions) when the recipient was attending (facing the sender), but would use more tactile gestures and actions when the recipient was non-attending (oriented away from the sender). I collected data from 10 individuals using all-occurrences sampling and an ethogram to score behaviors from video recordings. In 1,143 interactions, …

Electrophysiological And Behavioral Working Memory Differences Between Musicians And Non-Musicians, Benjamin P. Richardson

All Master's Theses

The current study examines the P300 brainwave and working memory differences between musicians and non-musicians. Differences in aspects of recorded electrical brain activity have been used to quantify differences in updating processes of working memory possibly related to differences in amount of music experience. The current study is designed to partially replicate and enhance a method previously implemented in research describing how music experience may be associated with differences in visual processing as well auditory working memory and executive function. Behavioral data were collected using six standardized subtest measures of the TOMAL – II, followed by ERP recordings during a …

Intradimensional Variability With Numbers And Alphabetical Letters In Conceptual Rules, Thomas Henry Clayton

All Master's Theses

Subjects were assigned to bidimensional rule problems that contained either 5, 10, or 15 levels of intradimensional variability. The stimuli consisted of numbers and alphabetical letters. There were no performance differences by either males or females when the number of levels within each rule was increased. There was a significant difference in performance among the three rules (disjunctive, conditional, and biconditional), however, the conditional was more difficult than the biconditional which is inconsistent with earlier research.

Experimenter Bias Effect At Varying Levels Of Motivation, Leslie Marie Slade Gray

All Master's Theses

This study examined the effects of experimenter motivation upon the experimenter bias effect on a person perception task. It was hypothesized that the experimenter bias effect would decrease as reward and threat of punishment increased.

Thirty-five experimenters were randomly assigned to five treatment groups including a control group, two reward groups, and two punishment conditions. Each experimenter administered the photo task to two subjects. The results failed to support the experimental hypotheses.

A Comparison Of Verbal And Geometric Stimuli In Concept Learning, Robert William Greenway

All Master's Theses

Subjects classified stimulus patterns into positive or negative instances of the concept according to either an attribute identification (AI) problem or a rule learning (RL) problem. Four types of stimulus materials were used: verbal stimuli (V), geometric stimuli (G), or two combinations of these modes, verbal geometric (VG) or verbal colored (VC). The only main effects that were significant were the Type of rule and Type of problem. Some interactions were obtained between these factors and the stimulus mode employed.

The Effects Of Truth Table Pretraining And Intradimensional Variability On Rule Learning And Attribute Identification Tasks, Eric S. Gebelein

All Master's Theses

Ss were required to sort geometrical patterns into positive or negative instances. According to (a) an attribute identification problem (wherein one of three conceptual rules was given: Disjunctive, Conditional, or Biconditional) or (b) Rule learning problem (wherein the two relevant attributes were given: either yellow, triangle or blue, circle). Intradimensional variability for each condition was either five, seven, or nine levels. The Rule effect was the only significant source of variance even though performance did worsen as intradimensional variability was increased.

False Physiological Feedback And Acceptance Of A High Fear Message, Michael T. Gray

All Master's Theses

This paper presents an attempt to differentiate between the drive reduction and parallel response theories as explanations of results obtained in fear communication research.

Forty-eight subjects were divided into four equal groups and while listening to a high fear message, three groups received false GSR feedback. The fourth group (control) received no feedback. The results failed to differentiate between the two theoretical models and also failed to support findings of an earlier study which used similar feedback techniques.

It was concluded that further research using false feedback techniques needs to be done.

Effects Of Volition And Justification On The Arousal Of Dissonance During Performance Of A Dull Task, George Roger Schoenhals

All Master's Theses

The present study seeks to add a modest degree of clarification to the present condition of dissonance theory. More specifically, its main purpose is to help define certain conditions for the arousal of cognitive dissonance.

The Effects Of Motivation Level And Task Difficulty On Performance On A Vigilance Task, Donald C. Johnston

All Master's Theses

Although many variables affecting vigilance behavior have been identified, there has not been substantial agreement on the importance of these variables as contributors either to performance decrements often found in laboratory research or to performance levels in industrial inspection tasks. Two variables of presumed importance are level of motivation and task difficulty. The purpose of the present experiment was to assess the main and interactive effects of these variables on performance on a task which approximated more closely an industrial inspection task than have the bulk of traditional vigilance studies.

Concept Identification As A Function Of Three Semantic Dimensions, Richard Eugene Edwards

All Master's Theses

It is the purpose of the present study to determine the differential effects of the three primary semantic dimensions on the ability of Ss to solve a concept identification problem. It was hypothesized that the performance level, as measured by a criterion of learning ten successive responses containing no more than one error, time to completion, and the total number of errors, will be higher for Ss working on the evaluative dimension than for Ss working on the potency or activity dimensions. Two additional hypotheses were formulated in an attempt to answer the following questions: 1) Is the ability to …

The Effect Of Dominance Level When Using Mediated Generalization To Facilitate Concept Formation, Delbert Smith Mchenry

All Master's Theses

This investigation was concerned with demonstrating differences in order of concept attainment as a function of the degree of association between a concept instance and concept response, using mediated generalization.
