ORCA members conduct research related to animal behavior and training. These research projects help improve the care and training of both domestic and exotic animals. Projects are conducted in a variety of settings, including animal rescues and shelters, zoos, and in homes. ORCA members often work together on projects, with senior members teaching and advising newer ORCA members.
ORCA research has been published in academic journals and has been presented at national and international conferences. The results directly benefit other institutions and professionals who are concerned with animal welfare.

Appropriate car riding with dogs is important for the dog’s and owner’s safety. Two dogs who display excessive panting are participating in this study. To teach them to do ride appropriately we are training the dogs to relax on a mat or blanket. To teach the dogs to relax we are using constructional affection which consists of petting the dogs until they are relaxed on the mat or bed. Our question is can a relaxed behavior be taught on an item (such as a blanket or bed) and if so, how would we best generalize this behavior to a new environment such as a car?

Autoshaping is produced by repeated non-contingent presentations of a preferred stimulus immediately following the illumination of a manipulandum. The result is consistent operation of the manipulandum (Brown & Jenkins, 1968). Autoshaping shaping has been observed in both pigeons and humans (Gonzalez, 1974; Picker & Poling, 1982; Wilcove & Miller, 1974; Pithers, 1985). When different stimuli are paired with different probabilities of food delivery, allocation of autoshaped responses varies accordingly (Picker & Poling, 1982). The simultaneous choice between these stimuli has been shown to be a sensitive dependent measure of autoshaped response strength (Picker & Poling, 1982). Experimenters studying autoshaping in humans have used levers similar to those in animal operant chambers and coins as the stimulus delivered noncontingently based on FT schedules (Wilcove & Miller, 1974; Pithers, 1985). This study was an attempt to replicate the Picker and Poling results with humans using the portable operant research and teaching laboratory (PORTL) designed by Rosales-Ruiz and Hunter (2014). This study used the presentation of different buttons as CS’s and the delivery of clicks followed by tokens as the stimuli to be delivered. Simultaneous presentation of the three buttons followed by 3 different schedules of reinforcement was used to replicate the choice trials of Picker and Poling. Successful replication of the autoshaping phenomenon was achieved. Analysis of the results indicated that the autoshaped responding observed by our subjects was an operant phenomenon. Supporting data and directions for future research will be discussed.

Researchers sometimes use conditioned reinforcers that are delivered after a specific number of responses to help facilitate performances on large-ratio schedules (e.g. Findley and Brady, 1965). Sometimes the stimuli that are used as conditioned reinforcers are “paired” with the unconditioned reinforcer before they are used on the large ratio schedule, other times they are not (e.g. Stubbs, 1971). The current experiment explored three types of stimuli and their ability to maintain college students’ performance on a large-ratio schedule. The first stimulus was paired with a conditioned reinforcer, the second type was a novel stimulus, and the third was introduced outside of the context of the task but was not paired with anything. The experiment consisted of five phases. After establishing an FR5 performance, each of the three stimuli and an extinction condition were tested to see if they could facilitate performance on an FR100. Overall, the results showed that the stimulus that was paired with the conditioned reinforcer and the novel stimulus were able to facilitate performance on the FR100, the stimulus that was given prior exposure but no pairing with a conditioned reinforcer did not facilitate performance.

Due to changes in national legislation and public awareness, new attention is being paid to emergency planning and management of both household pets and captive wildlife. Help with training relating specifically to emergency preparedness is a growing area in applied animal behavior. This project provides one example of how backward chaining, stimulus prompting, and transferring stimulus control can be used to train a household pet (a domestic cat) to go to a designated place of safety during a tornado when the owner is away from home. The learner in this study was a domestic shorthair household pet adopted from a local animal shelter. Training domestic animals and captive animals to go independently to a safe location can improve animal welfare. Similar projects could increase human compliance to evacuation procedures and restrictions, protect critical endangered species and zoo assets, and enhance public perception of facilities housing captive animals. Training domestic animals in safety behaviors can also be a valuable educational tool when training children about emergency situations and responses and can be a great way to share information and increase excitement for behavior analysis within the community.

Many students who are preparing for college are not aware of the wide variety of careers that involve working with animals. This education program is designed to give local high school students a unique opportunity to explore behavior analysis and participate in hands-on work with animals. The curriculum consists of classroom learning and hands-on projects where they are able to apply the techniques they have learned in the classroom.

The phenomenon of stimulus equivalence has been demonstrated mainly with humans. However, dog owners have anecdotally reported equivalence (or what appears to be equivalence) in their canine companions. The present experiment tests the possibility of equivalence with a 10-year-old-female-Husky-Doberman. During the first phase of the experiment the dog was trained to perform identity matching and was successful with minimal training. During the second phase (A-B training) the dog was trained to perform name-object relations, and then was trained symbol to object relations (C-B). Finally, the dog will be tested on name-symbol relations (A-C). Results are in progress.

Common reinforcers used while training dogs include food, toys, and access to favorite activities. Gentle stroking and petting is a less recognized, but equally effective reinforcer. The present study is an experimental demonstration of the use of touch as a reinforcer to teach acceptable behaviors to dogs. Five shelter dogs that jumped up on people were chosen as subjects. Five conditions were used to determine which environmental antecedents resulted in the dog jumping. These conditions included entering the dog’s kennel with a rope toy, bowl of food, or a leash, entering the kennel while talking to the dog and petting the dog, and entering the kennel but doing nothing. Using a systematic petting procedure known as Give Them Love, touch was used as a reinforcer to teach alternative behaviors in all conditions where jumping had occurred. The study used a multiple baseline design across conditions and across dogs. The intervention resulted in an immediate reduction in jumping and an increase in sitting and lying for all dogs. For dogs that required training in multiple conditions, training time decreased for each subsequent condition.

Animal shelters around the world struggle to get dogs adopted and to ensure dogs have a high quality of life while at the shelter. Shelter dogs ideally should receive proper medical care, accurate temperament assessments, appropriate environmental enrichment, and individualized behavior programs. This project will provide a sustainable behavioral system that addresses the job needs of staff and volunteers and the care of the dogs. A four-level volunteer training program teaches volunteers to use job aides to insure the shelter is a healthy and enriched environment for the dogs, conduct behavior assessments, and implement individualized training programs for each dog. Dogs receive training in one or more of the following areas based on a behavior assessment: fear, aggression, and how to politely and patiently solicit and receive attention from humans. The ultimate goal is to reduce euthanasia rates and increase successful adoptions.

Dog trainers manipulate the number and size of treats they deliver, such as by “jackpotting” (delivering multiple treats for especially good behavior) or giving very small treats to avoid satiation. However, not much is known about how such manipulations affect training. This study uses a paired-choice preference assessment to determine if there is a preference for one large treat or two smaller treats. Once the preference is determined, the preferred and non-preferred treats will be tested on actual training tasks to determine if there is a correspondence between the preference assessment and the performance on the training task. The subject for this study is a nine-year-old Chihuahua mix. In the preference assessment, the dog is presented with two bowls, each covered with a visual stimulus. A red circle covers the bowl containing one large treat and a blue square covers the bowl containing two small treats. The experimenter uncovers the bowl the dog noses. After a preference is determined, the effectiveness of one large or two small treats will be tested with a simple task (touching a target) and a difficult task (entering a crate that has previously been used for trips to the veterinarian). Results in progress.

Separation anxiety in dogs is a critical problem for pet owners. Owners with such dogs cannot leave the dog unattended for any length of time because of behaviors such as destructive chewing, barking and howling, and inappropriate elimination (even with otherwise housetrained dogs). Separation anxiety is commonly treated with a combination of behavioral and pharmacological interventions. The purpose of this study is to demonstrate that the relaxation induced by a drug can become conditioned to new environmental stimuli, after which the drug can be successfully withdrawn using a fading procedure. A dog with a history of generalized anxiety and separation anxiety was treated using a routine that included the benzodiazepine Oxazepam and several new environmental arrangements. After observing behavior changes such as a reduction in vocalizing and pacing, the dosage of medication was gradually decreased to zero, while leaving the routine of environmental arrangements in place. No change in behavior was observed as the medication was reduced. However, stopping the routine of environmental arrangements resulted in the immediate return of anxiety related behaviors. This was demonstrated using a multi-element single-subject design. Further research conditions explore the critical aspects of the control by the environment arrangements.
