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 …

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 …

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 …

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 …

Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson

Dissertations

In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in …

An Examination Of Several Variables Influencing The Efficacy Of The Gateway In Street Sign Configuration On Motorist Yielding Behavior, Miles Bennett

Dissertations

This study contains five different experiments that examine the effects of several variables influencing the effectiveness of the In-Street sign and various In-Street sign configurations. Experiment 1 and 2 compared the effects of the Gateway configuration using R1-6 signs to blank fluorescent yellow-green signs arranged in the Gateway configuration on motorist yielding to pedestrians in crosswalks. The results showed that the blank signs produced an increase in yielding from 7% to 33%, while the addition of the message and symbols to the sign increased yielding to 78%. Experiment 1, 2, and 4 examined the effects of different configurations of the …

Behavior Analysis Program To Improve Habits Of Physical Activity, Eating, And Sleeping, Ivan Noe Martinez Salazar

Dissertations

An Internet-based five-week duration program to improve “health habits” using behavior analysis principles and eHealth technology was developed and evaluated. The “health habits” include recurring behaviors that impact health status such as eating, sleeping, and physical activity.

Ten adult participants were recruited online from Mexico. A multiple baseline design was used and participants were randomly assigned into two different groups (i.e., ABBAA and AABBA groups). Participants received online training using videos describing the characteristics of the program and its components. Each participant recorded selected health behaviors using a Microsoft Excel® tool designed specifically for this program’s goal achievements. Participants reported …

Saliva Cotinine As A Measure Of Abstinence In A Lottery-Based Contingency Management Treatment For Smoking Cessation, Catherine M. Gayman

Dissertations

Contingency management decreases smoking by delivering monetary incentives contingent upon objective verification of abstinence. The present study investigated the effectiveness of monitoring saliva cotinine twice weekly in a contingency-management treatment for cigarette smoking using a cash prize-based payment system. Participants were randomly assigned to either a contingent reinforcement group or a non-contingent reinforcement group. The study began with five consecutive Baseline days during which participants smoked as usual, and was followed by four consecutive Shaping days, during which participants were asked to gradually decrease smoking. During the subsequent three-week Abstinence phase, participants submitted saliva cotinine and breath carbon monoxide samples …

The Neurobehavioral Consequences Of Gestational And Chronic Atrazine Exposure In Male And Female Sprague Dawley Rats, Jennifer L. Walters

Dissertations

The adverse health risks of exposure to the herbicide, atrazine, in humans are not fully understood. Although numerous studies have demonstrated atrazine to be an endocrine disrupter, the neurobehavioral consequences of atrazine exposure have not been thoroughly examined. The aim of this study was to investigate the effects of environmentally-relevant levels

of gestational followed by continued chronic atrazine exposure on motor function, learning and memory, anxiety, and striatal dopamine content in rodents. Pregnant Sprague Dawley rats were treated by gavage with 100 µg/kg atrazine (ATZ low), 10 me/kg atrazine (ATZ high), or vehicle on

gestational day l through postnatal day …

An Attempt To Establish Approval As A Learned Reinforcer, Kelly T. Kohler

Dissertations

Approval does not function as a powerful reinforcer for many children with autism, making it difficult to reinforce appropriate behavior in a functional and consistent manner. The current study first assessed the effects of establishing approval (“Nice,” accompanied by a smile and nod) and nonsense words as discriminative stimuli, with the intent that they might also become learned reinforcers. We conducted several experiments to assess the effectiveness of approval as a reinforcer, including tests on learning new responses (receptive, expressive, freeoperant, and simple simultaneous discriminations) and tests on the performance of previously mastered responses (receptive and expressive responses). Despite the …

The Use Of Response Interruption Redirection, Timeout, And Differential Reinforoement To Decrease Stereotypy, Jessica Korneder

Dissertations

Behaviors such as toe walking, hand flapping, nonfunctional vocalizations, and rocking are all examples of stereotypy. Stereotypy can occur at high rates in children with and without developmental delays (Smith & Van Houten, 1996). These behaviors can interfere with the acquisition of new skills (e.g., Dunlap, Dyer, & Koegel, 1983; Morrison & Rosales-Ruiz, 1997) and social interactions (Jones, Wint, & Ellis, 1990). The purpose of this study was to assess the effectiveness of response interruption and redirection (RIRD), time-out, and differential reinforcement of other behavior (DRO) in reducing vocal and motor stereotypy with children who engage in automatically reinforced high-rates …

Evaluation Of Novel Κappa Opioid Agonists Alone And In Combination With D-Amphetamine On Locomotor Activity In Sprague-Dawley Rats Evaluation Of Novel Κappa Opioid Agonists Alone And In Combination With D-Amphetamine On Locomotor Activity In Sprague-Dawley Rats, Mary Melissa Peet

Dissertations

Stimulant abuse is a widespread problem that often leads to detrimental health and social consequences. Currently, there are no FDA-approved pharmacotherapies available as a treatment option for stimulant abuse or the prevention of relapse. Drugs targeting kappa opioid receptors (KOR) are under investigation as a potential pharmacotherapy. KOR agonists have been shown to modulate dopamine levels within brain reward pathways, thereby producing anti-addictive effects. Traditional KOR agonists unfortunately tend to produce untoward side effects, including sedation, limiting their therapeutic utility. Structurally different from traditional KOR agonists, salvinorin A (salvA) may produce less sedating effects while still exerting anti-addictive properties. SalvA …

The Perception Of Distance On A Real Geographic Slope, David Alan Bunch

Dissertations

Ooi, Wu, and He (2001) have shown that for objects resting on flat, horizontal surfaces, those that appear in the lower sector of the visual field are perceived as close to the observer and objects located near the visual horizon are perceived as further from the observer. Researchers have hypothesized that observers utilize the angle subtended between the horizon and the line of sight to the target object as information for distance.In a previous investigation Hajnal, Bunch, and Kelty-Stephen (2014) showed that an object’s physical angle of declination below the horizon is not uniquely utilized when making distance estimates to …

The Impact Of Sleep Restriction (Nap Deprivation) On Preschool Children's (Aged 3-5) Emotional Response, Hui-Ya Gail Han

Dissertations

This study examined the effect of nap restriction on 3- to 5-year-old habitually napping children’s emotional responding. It was predicted that the intensity of emotional stimuli would moderate the relationship between nap restriction and the magnitude of emotional responding. Specifically, following nap restriction, the emotional responses to stronger stimuli would be amplified, while the emotional responses to weaker stimuli would be reduced. Emotional stimuli, were classified into four categories: strong negative, weak negative, weak positive, and strong positive. Facial electromyography was measured to reflect preschoolers’ emotional responses. The results indicated emotional responses to both strong negative and positive stimuli were …

Effects Of Animal Management Changes On The Activity Budgets And Walking Rates Of Zoo Elephants, Angela Dawn Mackey

Dissertations

The current study aimed to assess the effects of two management strategies, weekly rototilling of the enclosure and the provision of unpredictable foraging opportunities, on the daily behavior of six elephants housed at the San Diego Zoo. Observations took place from January to June 2013 and were conducted throughout a 24- hour period. The study was divided into three phases, each two months in duration. During the first phase (baseline) no changes were made to the current management routine of the elephants. In Phase 2, rototilling of the elephant enclosures was increased from once monthly to once per week, while …

Problem and Purpose

Innovative solutions in national defense are needed to respond to national security threats in our uncertain environment. Leader attitudes and behaviors have a substantial impact on innovation. Unfortunately we did not completely understand the effect of leader attitudes and behaviors on innovation and the team dynamics that lead to innovation, especially in the military. The purpose of this study was to determine how leadership attitudes and behaviors contribute to product innovation within the U.S. Navy and how leadership emerges within this complex adaptive system of innovation.

Method

The research was a qualitative design based on a multiple …

Influences Of Tnt-Food Pairings On The Performance Of Mine Detection Rats In Early Training Stages, Timothy L. Edwards

Dissertations

Anti-Persoonsmijnen Ontmijnende Product Ontwikkeling (APOPO), a Belgian nongovernmental organization headquartered in Tanzania, trains giant African pouched rats (Cricetomys gambianus) to detect land mines and deploys the rats for operational use in countries afflicted with mines and explosive remnants of war. In the present study an evaluation of the influence of ongoing scent-food pairings on the performance of the rats in early mine detection training was conducted. Twenty young rats in APOPO’s mine detection rat program were divided into two groups and exposed to five daily stimulus-food pairing sessions each week. For the experimental group the stimulus was the …

Slope Of Change Through D-Cycloserine Facilitation Of Exposure Therapy In A Social Anxiety Population, Christina M. Sheerin

Dissertations

The present study sought to add to a growing base of research investigating approaches that facilitate the therapeutic effects of exposure-based therapy for social anxiety disorders. In particular, the approach involves the use of medication adjuvants that work in conjunction with therapeutic learning. This work translates findings from preclinical work to further our understanding of the neurobiological mechanisms that impact extinction learning. Among others, a promising method has been found with the use of D-cycloserine (DCS), a partial NMDA receptor agonist. Evidence of its positive impact in preclinical work has led to its application to clinical populations who suffer from …

Dynamics Of Perceptual Organization In Complex Visual Search: The Identification Of Self Organized Criticality With Respect To Visual Grouping Principles, Attila Jozsef Farkas

Dissertations

The current project applies modern quantitative theories of visual perception to examine the effect of the Gestalt Law of proximity on visual cognition. Gestalt Laws are spontaneous dynamic processes (Brunswik & Kamiya, 1953; Wertheimer, 1938) that underlie the principles of perceptual organization. These principles serve as mental short-cuts, heuristic rule-of-thumb strategies that shorten decision-making time and allow continuous, efficient processing and flow of information (Hertwig & Todd, 2002). The proximity heuristic refers to the observation that objects near each other in the visual field tend to be grouped together by the perceptual system (Smith-Gratto & Fisher, 1999). Proximity can be …

Sharing: Social Behavior In Situations Of Risk, Stephanie Theresia Stilling

Dissertations

The present study will experimentally investigate human cooperation (sharing) in a laboratory foraging task that simulates environmental variability and resource scarcity (shortfall risk). Specifically, it investigates whether a risk-reduction model of sharing developed by evolutionary biologists (derived from a risk-sensitive optimization model known as the energy-budget rule) could predict human cooperative behavior. Participants respond to earn points exchangeable for money when point gains were unpredictable. Failures to acquire sufficient points result in a loss of accumulated earnings (a shortfall). Participants are given the choice between working alone or working with others. The difficulty of meeting the earnings requirement is manipulated …

Assessing The Generality Of A Bout Analysis In The Description Of Operant Behavior, J. Adam Bennett

Dissertations

Operant psychologists typically use response rate as a primary measure of behavior. Although response rate has proven a useful dependent measure resulting in the identification of many important behavioral regularities, many researchers have argued that the measure has significant limitations. Primarily, response rate treats all responses in the measured response class as functionally equivalent and distributed uniformly across time. This conceptualization of behavior is useful as long as all responses are affected similarly by different experimental manipulations. Research has shown, however, that certain manipulations differentially affect responses with relatively short or long interresponse times. This has led to a new …

Motivating Operations In Drug-Discrimination, Amin Duff Lotfizadeh

Dissertations

Motivating operations (MO) play an important role in learning and performance. According to the behavior analytic conceptualization, MOs alter the probability of responses that lead to relevant reinforcers and alter the reinforcing “value” of those reinforcers (e.g., Michael, 1982, 1993). Recent research suggests that one way in which MOs influence stimulus control is by influencing the control of behavior by discriminative stimuli. Interestingly, in studies with nonhumans, such an effect is commonly observed when lights and tones are used as discriminative stimuli, but not when drugs are used. Procedural differences across studies involving the species studied, the measurement system used …

Accessing Learning In The Adult Zebrafish With A Novel Associative Learning Task, David Joseph Jouandot Ii

Dissertations

The zebrafish (Danio rerio) is accepted in the developmental and genomic communities as a model organism. However, the capacity for the zebrafish as a behavioral model has yet to be fully acknowledged. The research presented provides evidence validating the novel task, aids in gaining a better understanding of the learning processes, and identifies individual differences. The novel associative learning task differs from any present well established behavioral model and lends itself to future development. The task provides the zebrafish community with a high output behavioral task which is readily replicated and allows one researcher to test between eight …

Tactile Behavior In A Group Of Captive Rough-Toothed Dolphins As A Function Of Opportunities To Play With Objects, Kelly Ann Caffery

Dissertations

Cetaceans live in complex physical and social environments that are frequently changing. In contrast, the captive environment for marine mammals is often lacking in stimulation. As a result, enrichment is often used to increase species-typical behaviors and enhance the well-being of the animals. The purpose of this study was to compare the effects of enrichment objects on the social behavior of a group of seven captive rough-toothed dolphins (Steno bredanensis). Observations of this species in the wild suggest it may have a particular affinity for tactile and object play behaviors. Therefore, these behavior categories were a primary focus …

Effects Of Food Dispersion On Dominance Related Behaviors In Garnett's Bushbaby (Otolemur Garnettii)?, Kyle Daniel Edens

Dissertations

Socio-ecological theorists tie primate social structure diversity to variations in habitats within which primate species reside. This premise permits laboratory researchers to investigate specific factors that influence or relate to social structure formation and maintenance. The focus of the current investigation was three fold. We first aimed to determine the relationships between traditional and non-traditional behavioral measures of dominance, then evidence for dominance hierarchy formation was examined, and various hypotheses were tested to discern if adjustments in the foraging context altered social behaviors in Garnett’s bushbaby (Otolemur garnettii). It was determined that animals likely to displace conspecifics were …

The Relationship Between Suicide Ideation And Parasuicide: An Electrophysiological Investigation Using The Loudness Dependence Of Auditory Evoked Potential, Angelika Marsic

Dissertations

The loudness dependence of the auditory evoked potential (LDAEP) has been proposed as a promising valid and a non-invasive indicator of behaviorally relevant central 5-HT functioning. There is limited research on the utility of the LDAEP in discriminating individuals who engage in various degrees of suicidal behavior. The primary purpose of the present study was to examine if the LDAEP, as a measure of central serotonergic functioning, can be useful in distinguishing groups of individuals who: (a) solely experience suicidal ideation (SI group); (b) experience suicidal ideation and have engaged in deliberate self-harm acts (SH group); and (c) individuals with …

Genetic Associations With Borderline Personality Disorder And Related Traits And Behaviors, Casey Roy Guillot

Dissertations

Borderline personality disorder (BPD) and related traits and behaviors have been linked to a number of neurotransmitter systems, including serotonin, norepinephrine, GABA, and dopamine. Because three human single-nucleotide polymorphisms (SNPs), COMT rs4680, GABRA2 rs279871, and SNCA rs356195, have been linked to the abovementioned neurotransmitter systems, they may be associated with BPD and related traits and behaviors. The purpose of the current study is to examine associations of COMT rs4680, GABRA2 rs279871, and SNCA rs356195 with both categorical and continuous measures of BPD and with continuous measures of impulse control and self-harm in a nonclinical sample. Healthy volunteers were categorized into …

Personality Assessment In African Elephants (Loxodonta Africana), Kristina Marie Horback

Dissertations

The following study assessed personality in twelve African elephants using both observational behavior coding and standardized trait rating methods, thus demonstrating consistent individual differences across time and contexts. During the summer of 2010 and 2011, over 640 hours of behavioral data were collected onsite at the San Diego Zoo Safari Park in Escondido, CA. Four coding-based personality traits were determined after analysis: PLAYFUL, CURIOUS, TOLERANT, and, AGGRESSIVE. This data was then compared to survey ratings completed by the animal keeper staff during both summers. Four rating-based personality traits resulted from this analysis: PLAYFUL, CURIOUS, TIMID, and, AGGRESSIVE. All eight composite …
