Evaluation Of The Efficacy Of A Rat Agreement Based Reinforcement Procedure, Katherine B. Lalonde
Evaluation Of The Efficacy Of A Rat Agreement Based Reinforcement Procedure, Katherine B. Lalonde
Masters Theses
Since 2007, giant African pouched rats (Cricetomys gambianus) have been used successfullyfor detecting Tuberculosis (TB) positive patients.The rats are trained to detect TB-positive sputum samples through the use of operant conditioning techniques, in which an indicator response is rewarded with food. If the rats are to be used for first line screening of patients reinforcement could not be provided because the true status of the sample would be unknown. The present study evaluated the effects of a reinforcement-for-agreement procedure that could be used to reinforce indication responses when the true status of the sample is unknown. Four rats evaluated 100 …
Influences Of Tnt-Food Pairings On The Performance Of Mine Detection Rats In Early Training Stages, Timothy L. Edwards
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 …
Sharing: Social Behavior In Situations Of Risk, Stephanie Theresia Stilling
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 …
Computerized Behavioral Activation Treatment For Major Depressive Disorder And The Effects On Sexual Desire, Anthony G. Bonita
Computerized Behavioral Activation Treatment For Major Depressive Disorder And The Effects On Sexual Desire, Anthony G. Bonita
Dissertations
The present study was designed to examine the effects of a computerized behavioral activation treatment program on sexual desire, sexual behavior, and depression symptoms. Seven adults who met criteria for either major depressive disorder or dysthymic disorder were recruited from Kalamazoo, Portage, and surrounding areas in Southwestern Michigan. All participants completed at least five sessions of behavioral activation treatment, and six out of seven participants completed all ten sessions. Symptoms of depression, sexual desire, and sexual behavior were assessed at pretreatment and before each treatment session through a combination of the Beck Depression Inventory – II (BDI-II), the Revised Hamilton …
Use Of A Gateway In-Street Sign Treatment To Increase Yielding To Pedestrians At Crosswalks, Miles K. Bennett
Use Of A Gateway In-Street Sign Treatment To Increase Yielding To Pedestrians At Crosswalks, Miles K. Bennett
Masters Theses
An important goal to reduce the number of collisions between motorists and pedestrians is to increase motorist’s yielding right-of-way to pedestrians in crosswalks. The current study addresses this goal. A Gateway installation of instreet signs (one in-street sign installed between the two travel lanes in each direction and one on both edges of the roadway in each direction) was evaluated on multilane roads. The first experiment compared the efficacy of adding multiple in-street signs used in a gateway configuration with a single sign between the two travel lanes in each direction. The second experiment compared the in-street sign gateway treatment …
The Effects Of Preprinted Versus Handwritten Safmeds On Fluency, Samantha Fodrocy
The Effects Of Preprinted Versus Handwritten Safmeds On Fluency, Samantha Fodrocy
Honors Theses
Precision Teaching is an instructional evaluation technique used by educators to ensure that targeted skills are being achieved by learners (Moran & Malott, 2004). Say all fast a minute each day shuffled (SAFMEDS) is a specific PT influenced instructional strategy intended to develop fluency within timed trials (Eshleman, 2000). However, there is little empirical research related to the proposed effects of SAFMEDS. A recent study by Meindl and colleagues (in press) demonstrated the position of the text on SAFMEDS affected fluency. Results of this study suggest extraneous variables affect responding indicating a possible stimulus control issue. However, there were methodological …
