Impact of Training Method on Behavioral, Physiological, and Relationship Measures in HorsesIsernia, Lindsay Taylor 07 January 2021 (has links)
With a rise in concern for animal welfare, the equine world has started using positive reinforcement (R+); as such, horses often experience a combination of negative reinforcement (R-) and R+. I compared the effects of R- to a combination of positive and negative reinforcement (R-/R+) training. Horses were trained to walk across two visually discriminable liverpools (striped, Experiment 1; colored water, Experiment 2), each associated with either R- or R-/R+, and training type alternating across six days. I measured highest training criteria reached, prevalence of undesirable behaviors, salivary cortisol (pre- and post-training), time spent by the trainer in motionless human tests (pre- and post-training), and horses' preference for the two liverpools using concurrent choice. Across both experiments, I found no significant difference in the proportions of criteria reached between training types; horses engaged in mugging for longer periods of time in R-/R+ than R-; no significant difference between training types for the pre- to post-change of cortisol; a greater proportion of horses increased time spent with R-/R+ trainer than the R- trainer; and no difference between first choice in the preference test or time horses spent in proximity to the liverpool, based on the training type with which the liverpool was associated. Overall, I found few differences between R-/R+ and R-, which could be due to horses only having 30 min total training contact with either training, or my use of relatively low intensities of R- and R+. / Master of Science / The equine world has started using positive reinforcement (R+), such as providing treats. Often horses experience a combination of negative reinforcement (R-) and R+, such as having rein pressure released and being given a treat. I compared effects of R- to a combination of positive and negative reinforcement (R-/R+) training. Horses were trained to walk across two visually distinct liverpools, a 1 m X 2.7 m shallow pool, (striped, Experiment 1; colored water, Experiment 2) each associated with either R- or R-/R+, and training type alternating across six days. I measured highest training level reached, occurrence of undesirable behaviors, salivary cortisol (a measure of stress), time spent by the trainer in motionless human tests, and horses' preference for the two liverpools. Across both experiments, I found no significant difference in the proportions of criteria reached between training types; horses investigated the trainer for treats for longer durations in R-/R+ than R-; no significant difference between training types for the pre- to post-change; a greater proportion of horses increased time spent with R-/R+ trainer than R- trainer; and no difference between first choice in the preference test or time horses spent in proximity to the liverpool, based on the training type with which the liverpool was associated. Overall, I found few differences between R-/R+ and R-, which could be due to horses only having 30 min total training contact with either training, or my use of relatively low intensities of R- and R+.

Equines Do Not Live for Grass Alone: Teaching Equines with Social InteractionNishimuta, Maasa 05 1900 (has links)
Most horse training methods heavily rely on negative reinforcement and punishment. However, there is a movement in the horse community to utilize positive reinforcement to meet training goals. Although food has been used effective as a reinforcer with horses, social interaction has also been demonstrated to function as a positive reinforcer for animals. Utilizing social interaction as a reinforcer may lead to several benefits for both the trainer and animal. Some of the benefits can be improved relationships between animals and their caretakers and improved animal welfare. The purpose of this study was to apply Owens and Owens et al. previous research protocols to three equines to assess if social interaction, in the form of petting and gentle scratching, would function as a reinforcer. Using a changing criterion design, this study demonstrated that petting and gentle scratching could function as a reinforcer to teach three equines to stay and come in their natural environment.

Internal-External Locus of Control, Perception of Teacher Intermittency of Reinforcement and AchievementWelch, Linda N. 12 1900 (has links)
This study measured the relationships between locus of control, students' perception of the schedule of teacher reinforcement, and academic achievement. The Intellectual Achievement Responsibility questionnaire, Perception of Teacher Reinforcement scale, and Wide Range Achievement Test were used to measure these variables. All subscores of the Intellectual Achievement Responsibility questionnaire correlated significantly with achievement for the females, but no relationships were found for the males. Perception of the teacher as partially rewarding was significantly correlated with reading, spelling, and total achievement for the males and with reading and arithmetic achievement for the females. Perception of the teacher as partially punishing was significantly correlated with arithmetic achievement for the males, but was not related to achievement for the females.

Positive Parenting, Conduct Problems, and Callous-Unemotional TraitsClark, Julia E 18 December 2015 (has links)
The current study tested the association of both positive and negative aspects of parenting with callous-unemotional (CU) traits and conduct problems. Caregivers of 92 kindergarteners were recruited to complete a series of survey measures. Overall, parent-report of negative parenting practices was not associated with teacher report of conduct problems. However, parent report of positive parenting practices (i.e., warmth, positive reinforcement, positive communication and cooperation) was negatively associated with conduct problems and CU traits. Interactions between positive parenting variables and CU traits in their association with conduct problems indicated that positive reinforcement related more strongly to lower levels of conduct problem behavior for youth with high levels of CU traits. However, positive communication and cooperation related more strongly to conduct problems for youth with lower levels of CU traits. These associations suggest that parenting may play a role in the development of CU traits and conduct problems.

An evaluation of motivating operations in the treatment of food refusalBachmeyer, Melanie Hope 01 July 2010 (has links)
Previous research on the assessment of pediatric feeding disorders has shown that negative reinforcement (escape) plays a major role in the maintenance of food refusal and that escape extinction (EE) may be necessary in the treatment of severe food refusal. The current study examined the influence of two potential motivating operations (MOs) on escape from bite presentations for 3 children with severe food refusal: (a) noncontingent positive reinforcement (NCR) and (b) food satiation (as a result of enteral nutritional support). The abolishing effects of NCR on negative reinforcement for refusal behaviors were demonstrated in Experiment 1 when escape was allowed for food refusal and in Experiment 2 during demand fading across a hierarchy of bite placements. The interactive effects of NCR and food satiation on negative reinforcement for escaping bite presentations (within a hierarchy of bite placements) were demonstrated in Experiment 3. NCR abolished escape as a reinforcer and food satiation established escape as a reinforcer. The combined MO effects of NCR and food deprivation resulted in decreased refusal behaviors and increased acceptance across all bite placements in Experiment 3 even though escape was allowed. Results extend the existing bodies of literature on the competition between positive and negative reinforcement and the effects of specific biological conditions on escape-maintained behavior. Implications for treatment and future research are discussed.

Reducing Reliance on Supplemental Winter Feeding in Elk (Cervus canadensis): An Applied Management Experiment at Deseret Land and Livestock Ranch, UtahMangus, Dax L 01 August 2011 (has links)
Wildlife managers have fed elk in North America for nearly 100 years. Giving winter feed to elk can compensate for a shortage of natural winter range and may boost elk populations while also helping prevent commingling with livestock and depredation of winter feed intended for livestock. In contrast to these benefits of supplemental feeding, there are economic and environmental costs associated with feeding, and elk herds that winter on feeding grounds have a higher risk of contracting and transmitting disease. Brucellosis is of primary concern now, and Chronic Wasting Disease may be in the future. Many see the discontinuation of winter-feeding programs as a necessary step for decreasing the risk of disease spread due to high animal densities associated with feeding during winter. My research evaluated the use of behavioral training to reduce reliance on supplemental winter feeding of elk, while minimizing population reductions and human-wildlife conflicts. My study was conducted at Deseret Land & Livestock (DLL) in Rich County, UT, where managers at DLL have over 20 years of data on elk feeding during winters of varying intensities. I tested the effectiveness of range improvements, strategic cattle grazing, dispersed supplemental feeding, hunting, and herding to distribute and hold elk in desired areas during winter. I compared elk numbers on the feed ground during this study with historic data on DLL, and also contrasted elk responses with other comparable feed sites in Wyoming that served as controls. In 2 mild winters we completely eliminated elk feeding without incident and were able to reduce the quantity and duration of feeding during 1 severe winter. Since the conclusion of my study, DLL has further reduced quantity and duration of feeding during severe winters, and has completely eliminated feeding in light winters. Based on a Before After Control Impact (BACI) analysis, the reduction in the proportion of the elk population fed at the study site was significantly less than the proportion of the elk populations fed at the control sites in Wyoming (P = 0.057). Based on these results, I anticipate wildlife managers can decrease dependence on costly supplemental winter feeding and reduce the risks of disease while keeping human-wildlife conflicts at a minimum. This research illustrates an adaptive method that can enable wildlife managers to keep elk populations in northern Utah at or near their current size, while constraining disease outbreak and transmission risks within "acceptable" levels.

Creating Positive Experiences: Increasing Parent Participation In A Low Income Elementary SchoolCayer, Krista Stinson 02 July 2003 (has links)
Previous research has examined the effectiveness of placing parents on a variety of incentive programs which would increase their likeliness to participate in school related activities. That research suggested that establishing school as a reinforcing environment for parents was vital. Due to these findings, this study examined the effects of a token economy on parent involvement at a low-income elementary school. Teachers were trained in the data collection method, and parental behavior was observed on a daily, weekly and bi-weekly schedule. Measures of social validity were obtained through teacher and parent questionnaires.
The data from the research study suggested that the implementation of the token economy did increase the amount of parent participation, but only on a "micro" level. Parent involvement on a larger scale such as participation in after school activities such as PTA's and other large scale school related activities were not affected.

Shaping Cows' Approach to Humans Using Positive and Negative ReinforcementMorehead, Melissa L. 05 1900 (has links)
Negative reinforcement can be a powerful tool for behavior analysts, yet it is often overlooked as a treatment method. Pryor (1999) outlines a method for approaching a "timid" animal using a combination of negative reinforcement and positive reinforcement. When the animal stands still, the human operates a clicker, and then retreats from the animal. Gradually, the human moves closer to the animal through the clicking and retreating shaping process. Once the human is standing close enough, food may be offered as a positive reinforcer, and the negative reinforcer is canceled out. The purpose of this study was to experimentally demonstrate the click-retreat technique with cows. A multiple-baseline design across subjects was used to test this technique. Results show that the click and retreat technique was effective. Results are discussed in terms of the difference between the click-retreat technique and systematic desensitization.

A Parent Training Program Combining Discrete Trial Training and Incidental Teaching in the Home EnvironmentJones, Lindsey 30 June 2009 (has links)
This study examined the effects of a parent training program teaching discrete trial teaching (DTT) and incidental teaching (IT) methods using a parent training manual. Three families with children between the ages of 5-6 diagnosed with Autism Spectrum Disorder (ASD) participated. Both parents received parent training although Parent A received training from the experimenter and Parent B received training from Parent A. The parents taught their children one skill each from three categories: communication, self-care routines and a household expectation. This study sought to expand upon the literature in the realm of combining DTT and IT as well as adding the dimensions of training in home environments in a short period of time and examined the role of one parent training the other. Results showed that all of the Parent As were able to learn and apply DTT and IT in teaching their children. All Parent A's were then able to teach Parent B's how to use DTT and IT without additional training from the experimenter. The generalization effects of learning skills in multiple environments with different people was also examined and discussed.

The Effects of Contingency Type on Accuracy and Reaction TimeAdams, Owen James 08 1900 (has links)
Positive and negative reinforcement contingencies have been compared in terms of preference, but the differential effects of positive and negative reinforcement on reaction time and accuracy with other variables controlled remain unclear. Fifteen undergraduate students participated in a sound discrimination task that involved random mixed-trial presentations of positive and negative reinforcement contingencies. The participants' goal was to correctly identify whether the tone was shorter or longer than 600 milliseconds. On positive reinforcement trials, the participants received feedback and money tallies only if they identified the sound length correctly, with each correct response in the positive reinforcement trials earning the participant 10 cents. On negative reinforcement trials, the participants received feedback and money tallies only if they identified the sound length incorrectly, with incorrect trials subtracting 10 cents from the participants' total money (which began at $4.00 to equalize the weights of the positive and negative reinforcement contingencies). Accuracy analyses showed a relatively curvilinear relationship between the number of errors for each participant and the binned duration of the sound stimulus, with no differences across the positive and negative reinforcement conditions. Results also indicated weak linear negative correlations at the single subject level between comparison stimulus duration and reaction time, with similar slopes between positive and negative reinforcement trials, and strong curvilinear correlations at the group level, indicating differences between grouped and individual analyses. Overall our results appear to support abandoning the distinction between positive and negative reinforcement as two separate behavioral processes.
