Habitat Use By Bottlenose Dolphins, Tursiops Truncatus, In Roanoke Sound, North Carolina, Shauna Marisa Mcbride

Dissertations

Information on the habitat use of a species is important to develop conservation efforts and management strategies for that species. Roanoke Sound, North Carolina is primarily a seasonal habitat for bottlenose dolphins, Tursiops truncatus, from late spring to early fall, but little information is known about how dolphins use this area. Transect survey data and opportunistic survey data collected by the Outer Banks Center for Dolphin Research from 2009 to 2015 were used to analyze dolphin habitat use. The objectives of this project were to: 1) identify areas that were important to dolphins, 2) determine which behaviors were observed …

The Effect Of Auditory Stimulation On Sleep Disruption In West Indian Manatee (Trichechus Manatus Latirostris), Natalija Lace

Dissertations

Florida manatees inhabit waterways where motorized boats are common. Although manatee mortalities resulting from boat strikes are well documented, the effect of boat noise on some manatee behaviors, including rest, has not been investigated. This study focuses on rest behavior and used a playback experiment with four manatees at the Lowry Park Zoo in Florida. We tested their responses to playback stimuli of either boat noise, silence, or manatee calls. A playback trial was initiated when the focal animal showed behavioral characteristics of rest.

Results showed that rest was interrupted in response to the playback of boat noise for each …

The Tootling Intervention With Classdojo: Effects On Classwide Disruptive Behavior And Academically Engaged Behavior In An Upper Elementary School Setting, Melissa Mchugh Dillon

Dissertations

The current study was designed to replicate and extend the literature on the effectiveness of a classroom intervention known as Tootling (Skinner, Skinner, & Cashwell, 1998) to include an interactive technological component, ClassDojo, to decrease disruptive classroom behavior as well as increase academically engaged behavior. Tootling is a peer-monitoring intervention that encourages students to report instances of appropriate behaviors they have seen their peers perform. Thus far, studies utilizing direct observation data to measure disruptive behavior during Tootling (Cihak, Kirk, & Boon, 2009; Lambert, 2014, Lambert el al., 2015, Lum et al., 2015; McHugh et al., 2014) have shown reductions …

Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone And 4-Methylmethcathinone, Michael D. Berquist

Dissertations

Recent escalation in the popularity of recreational synthetic cathinone (“bath salts”) use has prompted numerous scientific investigations of the neurochemical and behavioral effects of 3,4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC), two of the more common chemical constituents of these illicit “bath salts”. Previous neurochemical and electrophysiological studies have revealed that MDPV functions as a blocker, and 4-MMC as a substrate, at monoamine transporters, and both produce transient increases in extracellular monoamines. In addition, previous research has demonstrated that MDPV and 4-MMC support self-administration in nonhuman experimental subjects, and their rewarding effects are observed when paired with contextual cues in nonhuman models …

Increasing Vocal Behavior And Establishing Echoic Stimulus Control In Children With Autism, Joseph Shane

Dissertations

Many children with autism fail to demonstrate vocal-verbal behavior, including echoic behavior, as early as their typically developing peers. Some also make very limited vocal sounds in general, remaining mostly mute aside from crying or engaging in stereotypy. Echoic behavior involves auditory discrimination and matching, and functions as a beneficial, if not necessary, prerequisite for many other vocal-verbal skills. The purpose of this study was to develop and implement an echoic training procedure for primarily non-vocal children who did not demonstrate auditory discrimination in baseline. The intervention consisted initially of sessions in which any vocal sounds were reinforced. Then differential …

Session-By-Session Feedback From Psychotherapy Outcome Assessment: An Analysis Of Treatment Utility, Lynn Hallberg Hall

Dissertations

This study sought to examine the effect of providing outcome assessment data to therapists treating a sample of community adults seeking mental health services at two university training clinics. The participants (N = 41) were predominantly unmarried, Caucasian females, 19 to 39 years old, with a wide range of psychological problems. The therapists were trainees from master’s and doctoral programs in counseling and clinical psychology participating in their first clinical practicums. The Outcome Questionnaire 45-2 (OQ), an instrument designed for frequent measurement of client symptom, interpersonal, and social-role distress, served as the dependent measure. The OQ was designed to show …

Performance Of Individuals And Teams On Cryptographic Tasks: Factors That Affect The Consideration Of Alternative Strategies, Joseph Bihary

Dissertations

The two studies presented here examined factors that might affect teams’ and individuals’ tendency to follow outside advice when attempting to solve a complex problem known as letters-to-numbers. Past research on group dynamics suggests that a lack of group consensus or homogeneity reduces group members’ confidence in their group’s abilities, and may lead members both to seek and accept advice from outside the group. Study 1 experimentally manipulated group diversity in task performance strategies in order to investigate whether dyads whose members have divergent perspectives are more likely than homogeneous dyads to consider and use a problem-solving strategy presented from …
