Being Here And Now: The Benefits Of Belonging In Space And Time, Matthew Baldwin, Lucas A. Keefer Dec 2019

Being Here And Now: The Benefits Of Belonging In Space And Time, Matthew Baldwin, Lucas A. Keefer

Faculty Publications

Research suggests that a sense of belonging is a critical prerequisite of happiness and well-being. While some have focused on belonging provided by relationships, other work demonstrates the value of belonging in certain places. In the current research we join these efforts to understand belonging by offering a novel framework for exploring an understudied but no less fundamental aspect of human experience—time. We situate this framework within an existential analysis of human action and test general predictions about the psychological value of experiencing a sense of belonging in time, what we call temporal rootedness. Two samples (Studies 1 …


Assessing The Effects Of Psychopathy, Sadism, Aggression, And Boredom Proneness On Cyber Aggression Perpetration In Emerging Adults: Is Moral Disengagement To Blame?, Taylor Nocera Dec 2019

Assessing The Effects Of Psychopathy, Sadism, Aggression, And Boredom Proneness On Cyber Aggression Perpetration In Emerging Adults: Is Moral Disengagement To Blame?, Taylor Nocera

Dissertations

Prior research indicates that a number of dark personality traits (e.g., psychopathy and sadism) positively predict the perpetration of cyber aggression among emerging adults (e.g., Goodboy & Martin, 2015; Craker & March, 2016; Nocera & Dahlen, 2018); however, few studies have utilized psychometrically sound measures of cyber aggression developed for use with this population. Additionally, some traits that are theoretically relevant to cyber aggression (Koban, Stein, Eckhardt, & Ohler, 2018; Slonje & Smith, 2008; Varjas, Talley, Meyers, Parris, & Cutts, 2010) and have been useful predictors of other forms of aggression have received insufficient attention in the cyber aggression literature …


Person-Level Sources Of Continued Influence Effect: The Roles Of Attention Control, Intolerance Of Ambiguity And Conservatism, Jinhao Chi Dec 2019

Person-Level Sources Of Continued Influence Effect: The Roles Of Attention Control, Intolerance Of Ambiguity And Conservatism, Jinhao Chi

Dissertations

People continually rely on disinformation to make judgments after it is corrected or discredited. This phenomenon is termed the continued influence effect (CIE). Using a sample of 152 participants, the current study examined whether the CIE can be explained by a person’s political orientation, attention control (AC) levels, intolerance of ambiguity (IA) and need for specific closure (NSC). It was found that when political orientation was based on self-reports, the overall political conservatism did not predict the CIE (r = .13, p = .09) but economic conservatism did (r = .19, p < .05), suggesting that those with higher self-reported fiscally conservative attitudes may show more prolonged influence of disinformation. In addition, the overall AC levels did not predict the CIE (r = .08, p = .30), but the antisaccade scores reflecting the ability to inhibit automatic responses were a significant positive predictor of the CIE (r = .18, p < .05). Lastly, neither IA nor NSC significantly predicted the CIE (ps > .05). These findings were obtained with only one …


The Quiet Classroom Game With An Indiscriminable Contingency In A High School, Stefanie Schrieber Dec 2019

The Quiet Classroom Game With An Indiscriminable Contingency In A High School, Stefanie Schrieber

Master's Theses

The Quiet Classroom Game (QCG) is an interdependent group contingency utilized to decrease classroom noise levels, increase student engagement, and decrease disruptive behaviors in the classroom setting. The purpose of the current study was to investigate the effects of the QCG in three high school classrooms in the Southeastern United States. Classrooms were recruited based on teacher reports of excessive noise and high rates of disruptive behavior. A multiple baseline design with two intervention phases was utilized to examine the effects of the intervention. The first phase was the QCG alone, and the second phase was the QCG with an …


Processing Speed For Action And Semantic Memory, Tyler A. Surber Dec 2019

Processing Speed For Action And Semantic Memory, Tyler A. Surber

Master's Theses

Previous research suggests that the processing of affordances may require more perceptually relevant information than words can provide (Surber et al., 2018; Chainay & Humphreys, 2002). The present study investigates this hypothesis with the shoebox task used in Bowers and Turner (2003). A list of 81 object nouns (targets) and associated features (primes: affordance, semantic, and non-associates) was compiled from the McRae, Cree, Seidenberg, and McNorgan (2005) norms. Affordances denote possibilities for action in relation to the object (e.g. chair – sit), whereas semantic features indicate definitional characteristics (e.g. chair – has legs). Affordances and semantic features served as primes …


Elevated Adhd Symptoms As A Predictor Of Rule Violations Among Male Juvenile Offenders, Kathleen Lolley Ramsey Dec 2019

Elevated Adhd Symptoms As A Predictor Of Rule Violations Among Male Juvenile Offenders, Kathleen Lolley Ramsey

Master's Theses

Youth with ADHD are disproportionately at-risk for engaging in criminality and aggression relative to the general population, and this may be a function of underlying executive function deficits associated with self-regulation. More specifically, youth with ADHD may be susceptible to difficulties with behavioral regulation (impulsivity) and emotional regulation (e.g., managing feelings of anger). The current study sought to expand on previous research to examine the relationship between ADHD symptoms and aggression and the potential moderating effects of anger control among institutionalized youth. Archival data comprising a sample (N=119) of male adolescents who were admitted to a maximum-security residential facility were …


Expanding The Fear Of Loss Of Vigilance Theory: Using Intolerance Of Uncertainty, Responsibility For Harm, And Fear Of Sleep To Predict Nocturnal Panic Attacks, Nicole S. Smith Dec 2019

Expanding The Fear Of Loss Of Vigilance Theory: Using Intolerance Of Uncertainty, Responsibility For Harm, And Fear Of Sleep To Predict Nocturnal Panic Attacks, Nicole S. Smith

Master's Theses

Nocturnal panic involves experiencing panic attacks out of a sleeping state without obvious causes such as nightmares or loud noises. Roughly half of patients with panic disorder will experience nocturnal panic in addition to panic attacks while awake, or daytime panic. Like daytime panic, nocturnal panic also occurs in other disorders such as PTSD. The Fear of Loss of Vigilance theory is currently the only model available to explain nocturnal panic. It suggests that nocturnal panickers fear states in which they cannot easily react to or protect themselves from danger. Prior research using a self-report measure to differentiate nocturnal and …


Testing An Active Intervention To Deter Researchers' Use Of Questionable Research Practices, Samuel V. Bruton, M. Brown, Donald Sacco, R. Didlake Nov 2019

Testing An Active Intervention To Deter Researchers' Use Of Questionable Research Practices, Samuel V. Bruton, M. Brown, Donald Sacco, R. Didlake

Faculty Publications

Introduction: In this study, we tested a simple, active “ethical consistency” intervention aimed at reducing researchers’ endorsement of questionable research practices (QRPs).

Methods: We developed a simple, active ethical consistency intervention and tested it against a control using an established QRP survey instrument. Before responding to a survey that asked about attitudes towards each of fifteen QRPs, participants were randomly assigned to either a consistency or control 3–5-min writing task. A total of 201 participants completed the survey: 121 participants were recruited from a database of currently funded NSF/NIH scientists, and 80 participants were recruited from a pool …


The Effect Of Group Polarization On Opposition To Donald Trump, Marija A. Bekafigo, Elena V. Stepanova, Brian A. Eiler, Kenji Noguchi, Kathleen L. Ramsey Oct 2019

The Effect Of Group Polarization On Opposition To Donald Trump, Marija A. Bekafigo, Elena V. Stepanova, Brian A. Eiler, Kenji Noguchi, Kathleen L. Ramsey

Faculty Publications

Using focus groups, we examined support and opposition for Donald Trump prior to the 2016 presidential election. When ingroup members participate in discussion, this conversation alone typically strengthens and intensifies members’ initial attitudes. We used a pre‐ to post‐focus‐group questionnaire to assess attitudes toward Trump, his campaign, and policies. We argue that group polarization influenced people’s opinions about Trump such that attitudes became more extreme after discussion with like‐minded individuals. We report changes for Trump nonsupporters for which group polarization occurred on attitudes toward illegal immigration, political correctness, the military, women, and veterans after the group discussion. For each, level …


Demographic And Clnical Characteristics Of Military Service Members Hospitalized Following A Suicide Attempt Versus Suicide Ideation, Brianne J. George, Sissi Ribeiro, Su Yeon Lee-Tauler, Allison E. Bond, Kanchana U. Perera, Geoffrey Grammer, Jennifer Weaver, Marjan Ghahramanlou-Holloway Sep 2019

Demographic And Clnical Characteristics Of Military Service Members Hospitalized Following A Suicide Attempt Versus Suicide Ideation, Brianne J. George, Sissi Ribeiro, Su Yeon Lee-Tauler, Allison E. Bond, Kanchana U. Perera, Geoffrey Grammer, Jennifer Weaver, Marjan Ghahramanlou-Holloway

Student Publications

Psychiatric hospitalization for a suicide attempt (SA), rather than suicide ideation (SI) alone, is a stronger risk indicator for eventual suicide death. Yet, little is known about demographic and clinical characteristics differentiating those admitted for SA versus SI. Understanding these differences has implications for assessment and treatment. A retrospective review of electronic medical records (EMRs) was performed on service members (n = 955) admitted for SA or SI at the Walter Reed Army Medical Center between 2001–2006. Service members hospitalized for SA were younger compared to those hospitalized for SI. The proportion of women admitted for SA was significantly …


Situational Factors Influencing Receptivity To Bullshit, Mitch Brown, Lucas A. Keefer, Shelby J. Mcgrew Sep 2019

Situational Factors Influencing Receptivity To Bullshit, Mitch Brown, Lucas A. Keefer, Shelby J. Mcgrew

Faculty Publications

Individuals are motivated to maintain a sense of meaning, and enact cognitive processes to do so (e.g., perceiving structure in the environment). This motivation to find meaning may ultimately impact humans’ interpretation of "bullshit", statements intended to convey profundity without any meaning. Conversely, subtle cues threatening the meaningfulness of bullshit may elicit greater skepticism. Three studies tested situational factors predicted to heighten or diminish susceptibility to bullshit by changing motivations to seek meaning. We employed diverse methods including symbolic meaning threat (Study 1), social exclusion (Cyberball; Study 2), and manipulating cognitive fluency (Study 3). Taken together, the results indicate basic …


Firearm Availability And Storage Practices Among Military Personnel Who Have Thought About Suicide, Craig J. Bryan, Annabelle O. Bryan, Michael D. Anestis, Lauren Khazem, Julia Harris, Alexis May, Cynthia Thomsen Aug 2019

Firearm Availability And Storage Practices Among Military Personnel Who Have Thought About Suicide, Craig J. Bryan, Annabelle O. Bryan, Michael D. Anestis, Lauren Khazem, Julia Harris, Alexis May, Cynthia Thomsen

Faculty Publications

More than 60% of US military suicides occur at home and involve a firearm. Nearly all military firearm suicides (95%) involve a personally owned firearm. Nonmilitary data indicate that the risk of suicide is 6 times higher in households with a firearm, although this risk may be reduced if the firearms are kept unloaded and/or locked. Because attempts using firearms have very high fatality rates, safe firearm storage practices could be an important component of comprehensive suicide prevention in the military. This study examined associations of firearm ownership and storage practices with suicidal thoughts and behaviors among military personnel.


Reports Of Recovered Memories Of Childhood Abuse In Therapy In France, Olivier Dodier, Lawrence Patihis, Mélany Payoux Aug 2019

Reports Of Recovered Memories Of Childhood Abuse In Therapy In France, Olivier Dodier, Lawrence Patihis, Mélany Payoux

Faculty Publications

Recovered memories of abuse in therapy are especially controversial if the clients were not aware they were abused before therapy. In the past, such memory recovery has led to legal action, as well as a debate about whether such memories might be repressed, forgotten, or false memories. More than two decades after the height of the controversy, it is unclear to what degree such memories are still recovered today, and to what extent it occurs in France. In our French survey of 1312 participants (Mage = 33; 53% female), 551 reported having done therapy at some point. Of …


English Semantic Feature Production Norms: An Extended Database Of 4436 Concepts, Erin M. Buchanan, K.D. Valentine, Nicholas P. Maxwell Aug 2019

English Semantic Feature Production Norms: An Extended Database Of 4436 Concepts, Erin M. Buchanan, K.D. Valentine, Nicholas P. Maxwell

Student Publications

A limiting factor in understanding memory and language is often the availability of large numbers of stimuli to use and explore in experimental studies. In this study, we expand on three previous databases of concepts to over 4000 words including nouns, verbs, adjectives, and other parts of speech. Participants in the study were asked to provide lists of features for each concept presented (a semantic feature production task), which were combined with previous research in this area. These feature lists for each concept were then coded into their root word form and affixes (i.e., cat and s for cats) …


Overparenting And Young Adult Narcissism: Psychological Control And Interpersonal Dependency As Mediators, Nathan Alexander Winner Aug 2019

Overparenting And Young Adult Narcissism: Psychological Control And Interpersonal Dependency As Mediators, Nathan Alexander Winner

Dissertations

Overparenting, or “helicopter parenting,” is a unique style of parenting characterized by parents’ well-intentioned but age-inappropriate over-involvement and intrusiveness in their children’s lives. Recent research has linked overparenting to the development of narcissistic traits in young adults, although the mechanisms of this relationship remain unclear. Two plausible mechanisms include the parenting behavior of psychological control and the increased interpersonal dependency of the child. Psychological control is a construct that overlaps with overparenting and has been linked to both dependent and narcissistic traits. Similarly, interpersonal dependency is a key predictor of narcissistic traits. Therefore, the present study sought to examine psychological …


Weeding Through College Drinking: The Moderating Role Of Marijuana Use On Alcohol Use, Protective Behavioral Strategies, And Negative Consequences, Mallorie Carroll Aug 2019

Weeding Through College Drinking: The Moderating Role Of Marijuana Use On Alcohol Use, Protective Behavioral Strategies, And Negative Consequences, Mallorie Carroll

Dissertations

Rates of alcohol (60% monthly) and marijuana (20% monthly) use among college students remain a concern given students experience a wide range of negative consequences related to their use, especially hazardous use. Research supports the theory that protective behavioral strategies are effective strategies that one can use while engaging in alcohol and marijuana use to minimize the experience of negative consequences. However, research regarding protective behavioral strategies for marijuana is fairly new and the findings are inconsistent. Given the limited research regarding alcohol-use behaviors among college students who report alcohol and marijuana use, the purpose of this study was to …


Profiles Of Interest In Holland's Theory In Relation To Personality And Sex, Erica L. Mathis Aug 2019

Profiles Of Interest In Holland's Theory In Relation To Personality And Sex, Erica L. Mathis

Dissertations

The current study sought to expand the knowledge of latent profiles of vocational interest that are interpreted from a theory-driven perspective. The current study utilized a measure of Holland’s RIASEC interest types as a source of data to explore possible profiles through latent profile analysis. Using an MTurk sample of 303 adults, seven profiles were interpreted in the context of Holland’s theory, specifically using diagnostic signs of the theory to explain possible profile membership. The seven profiles were coined Low Profile Elevation, High Consistency SIA, Moderate Consistency Conventional Investigative, Undifferentiated, High Differentiation Conventional Dominant, High Consistency Investigative Artistic, and High …


Overparenting, Emotional Distress, And Subjective Well-Being: Facets Of Emotional Distress Tolerance As Mediators, Christopher M. Perez Aug 2019

Overparenting, Emotional Distress, And Subjective Well-Being: Facets Of Emotional Distress Tolerance As Mediators, Christopher M. Perez

Dissertations

Overparenting (OP) has been characterized by parental behaviors that encroach upon children’s ability to develop age-appropriate, autonomous emotional responses and behaviors. OP has been associated with poor mental health, decreased subjective well-being (SWB), and decreased emotional distress tolerance (EDT) in the emerging adult population. The present study investigated relationships between OP, EDT, emotional distress, and SWB. Additionally, the mediating role of EDT, as well as the parallel mediating roles of EDT facets (i.e., appraisal, absorption, tolerance, regulation), were assessed between OP and emotional distress, as well as SWB. Participants included 313 undergraduate psychology students from a mid-sized university in the …


Dependability Of Two Group Observation Methods Across Rater And Time, Kayla E. Bates-Brantley Aug 2019

Dependability Of Two Group Observation Methods Across Rater And Time, Kayla E. Bates-Brantley

Dissertations

Collecting efficient and reliable behavior assessment data is often a goal for school districts and school psychologists. Unfortunately, the most accurate methods of behavior observations, systematic direct observations (SDO), can be time-intensive and often requires specific training. This often minimizes the number of trained professional available for observation procedures. Planned activity check (PAC), a variation of momentary time sampling, has the potential to combine the accuracy of SDO with efficiency. However, few studies have evaluated the psychometric principals of PAC. The current study sought to evaluate the reliability and dependability of PAC by comparing PAC to an individual-fixed (I-F) SDO. …


Effect Of Mindfulness On Gratitude And Psychological Wellbeing, David Schultz Aug 2019

Effect Of Mindfulness On Gratitude And Psychological Wellbeing, David Schultz

Dissertations

Gratitude is a unique emotion characterized by the propensity to be thankful and appreciative for the positive aspects of one’s life as it stands in the present moment. It has been associated with higher levels of perceived belongingness and perceived social support, as well as psychological wellbeing. Similarly, mindfulness refers to nonjudgmental awareness and acceptance of the reality of the present moment. Mindfulness has also been shown to increase one’s connectivity and sense of cohesion with others. The present study examined whether increasing mindfulness in individuals yielded increased gratitude as well as the mediating effect of gratitude on the relation …


Is Parent-Initiated Triangulation Associated With Pathological Narcissism In Youth?, Lauren Marie Lee-Rowland Aug 2019

Is Parent-Initiated Triangulation Associated With Pathological Narcissism In Youth?, Lauren Marie Lee-Rowland

Dissertations

The current study examined the proposed link between parent-initiated triangulation (i.e., directly involving a child in parental conflict in such a way that he/she forms an alliance with one parent against the other parent) and pathological narcissism in a sample of 148 adolescents, ages 12-14. Moreover, the moderating influence that different parenting practices and styles (i.e., parental overindulgence, overvaluation, warmth, inconsistent discipline) have on the relation between parent-initiated triangulation and pathological narcissism was explored. Findings from the current study indicated that adolescent self-reported pathological narcissism was associated with higher levels of adolescent-reported triangulation and parental overvaluation and was negatively related …


Evaluation Of A Role-Playing Game To Improve Social Skills For Individuals With Asd, Kate A. Helbig Aug 2019

Evaluation Of A Role-Playing Game To Improve Social Skills For Individuals With Asd, Kate A. Helbig

Dissertations

Autism spectrum disorder (ASD) affects one in 59 children (Centers for Disease Control and Prevention, 2018). Impairments in social communication and restricted and repetitive behaviorsare often associated with debilitating outcomes for individuals with ASD. Therefore, it is critical to identify successful treatments to address the social deficits characteristic of ASD. This study investigated the effects of a role-playing game (RPG) on social skill acquisition for individuals with ASD. The primary dependent variable was skill acquisition within the context of the RPG setting. Generalization of skill acquisition outside of the game-context and social functioning was also evaluated. Results indicated that the …


The Relationship Between Painful/Provocative Training Experiences And Capability For Suicide Among Medical Students, Brittney L. Assavedo Aug 2019

The Relationship Between Painful/Provocative Training Experiences And Capability For Suicide Among Medical Students, Brittney L. Assavedo

Dissertations

The primary aim of this study was to examine the relationship between capability for suicide and painful and provocative experiences related to practicing within the medical profession (mPPEs) among students enrolled in a College of Osteopathic Medicine (n = 114). It was posited that frequency of engagement in mPPEs would predict scores on measures of capability for suicide above and beyond the effects of gender and painful and provocative experiences unrelated to practicing within the medical profession (PPEs). It was also posited that frequency of both witnessing and performing an mPPE would moderate the impact of curriculum component on capability …


Check-In/Check-Out With High School Students, Ashley Murphy Aug 2019

Check-In/Check-Out With High School Students, Ashley Murphy

Dissertations

Check-in/Check-out (CICO) has been shown effective in reducing problem behavior (PB) and increasing academically engaged behaviors (AEB) for elementary and middle school students (Mitchell, Adamson, & McKenna, 2017); however limited research has included high school students. The current study sought to evaluate the effectiveness and social validity of CICO for four high school students in a general education setting. During the initial intervention phase, two students refused to participate in the CICO process (i.e., did not attend check-ins or check-outs despite multiple efforts); therefore, CICO was ineffective for these students. For two other students, CICO was ineffective for improving behavioral …


Validation Of The Ask-Asd In A Sample Of Parents, Teachers, And Medical Students, Laura K. Hansen Aug 2019

Validation Of The Ask-Asd In A Sample Of Parents, Teachers, And Medical Students, Laura K. Hansen

Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that begins in childhood and manifests in social communication impairment and restricted, repetitive behaviors (American Psychiatric Association, 2013). Although accurate information about ASD is available through a variety of sources, this access to information may not translate into increased knowledge in parents, teachers, and medical professionals. A Survey of Knowledge of Autism Spectrum Disorder (ASK-ASD) was initially established as a reliable, valid measure of perceived and actual knowledge of ASD (Hansen, 2015). The current study evaluated the psychometric properties (i.e., factor structure, reliability, and validity) of the ASK-ASD in a sample of …


Effects Of A Brief Mindfulness Induction On Death-Related Anxiety, David M. Schultz, Randolph C. Arnau Aug 2019

Effects Of A Brief Mindfulness Induction On Death-Related Anxiety, David M. Schultz, Randolph C. Arnau

Faculty Publications

This study examined effects of a mindfulness induction on proximal and distal defense responses to mortality salience and negative affect. Three experimental conditions were included: mindfulness, mind-wandering, and worrying. Participants in the mindfulness condition underwent a mindfulness induction at the experiment’s outset, while participants in the other two conditions underwent a mind-wandering or worry induction. Inductions involved following guided audio instructions presented via headphones. All conditions (N = 77) underwent a mortality salience induction after experimental manipulation, involving a written exercise pertaining to one’s death. Results indicated fewer proximal responses in the mindfulness and mind-wandering groups, compared with the worrying …


Peer-Mediated Tootling With A Standardized Form And A Mystery Motivator In High School Classrooms, Sarah J. Wright Aug 2019

Peer-Mediated Tootling With A Standardized Form And A Mystery Motivator In High School Classrooms, Sarah J. Wright

Dissertations

Peer-mediated tootling with a standardized procedure was implemented along with a mystery motivator component to determine the effects on academically engaged and disruptive behavior in three general education high school classrooms. The intervention used an A/B/A/B design across all classrooms. The goal of the study was to determine if these components would increase academically engaged behavior and decrease disruptive behavior. Students were trained on tootling procedures with a standardized format, which included reporting on peers’ positive, prosocial behavior on a premade tootling slip with various behaviors that they could select as being observed, reading five random slips aloud, totaling the …


Emotion Reactivity, Emotion Dysregulation, And Non-Suicidal Self-Injury Among At-Risk Adolescents: A Multiple Mediation Analysis, Paula N. Floyd Aug 2019

Emotion Reactivity, Emotion Dysregulation, And Non-Suicidal Self-Injury Among At-Risk Adolescents: A Multiple Mediation Analysis, Paula N. Floyd

Master's Theses

Non-suicidal self-injury (NSSI) is defined as deliberate self-inflicted damage to bodily tissue without the intent to die. NSSI has been identified as a major health concern, as it is related to both poor psychosocial outcomes and increased suicide risk. NSSI is especially important to understand among adolescents, as age of onset is typically during adolescence and prevalence rates are highest among this age group. One of the most well-established correlates of NSSI is emotion dysregulation. While many studies have examined emotion dysregulation and its subcomponents in relation to self-injury, there has been far less work devoted to factors that may …


Discrepant Self-Perceptions As Predictors Of Rule Violating Behavior Among Juvenile Offenders, Kimberly Barajas Aug 2019

Discrepant Self-Perceptions As Predictors Of Rule Violating Behavior Among Juvenile Offenders, Kimberly Barajas

Master's Theses

Numerous studies have examined discrepancies between youths’ self-perceptions and others’ ratings across different domains of competence (i.e. academic, behavior, social) (e.g., Jia, Jiang, & Mikami, 2016; Kistner, 2006; Owens et al., 2007) and it is well-established that discrepant self-perceptions are risk factors for maladaptive outcomes (e.g., aggression, depression) in children and adolescents (David & Kistner, 2000; Jia et al., 2016; Kistner et al., 2006). Only one study has examined discrepant self-perceptions (e.g., perceptual bias) in a sample of male juvenile offenders (JOs) (Smith, Lynch, Stephens, & Kistner, 2015). This study sought to extend the literature examining discrepant self-perceptions within juvenile …


Vocal Response Of Bottlenose Dolphins (Tursiops Truncatus) To A Novel Stimulus, Lindsey Johnson Aug 2019

Vocal Response Of Bottlenose Dolphins (Tursiops Truncatus) To A Novel Stimulus, Lindsey Johnson

Master's Theses

Bottlenose dolphins utilize acoustic signals as their primary mode of communication. Although some aspects of dolphin vocal behavior are well understood, less is known about vocalizations in different behavioral contexts and how these vocal behaviors may indicate habituation and sensitization. The focus of this study was to investigate how bottlenose dolphins respond vocally to a novel stimulus. Archival data from three populations of bottlenose dolphins (N = 20) living in a human-care facility were exposed to a novel apparatus (a mirror) for 10 trials, each lasting 20 minutes. Five of the trials presented the mirror covered with an opaque …
