The Influences of a Topographically and Functionally Unrelated Operant on Response Allocation under Concurrent Continuous Reinforcement Schedules

Description: In the experimental analysis of behavior, response allocation is typically studied under concurrent interval schedules, with two response alternatives, in a static environment. The natural environment of the unfettered organism, however, is dynamic insofar as even frequently visited environments are rarely identical from encounter to encounter. Additionally, natural environments usually offer more than two concurrently available behaviors that are often scheduled for reinforcement contingent on… more

Variability in the Natural World: An Analysis of Variability in Preschool Play

Description: Children acquire many skills through play. These range from fine and gross motor skills, social skills, problem-solving, to even creativity. Creativity or creative engagement is frequently a component in early preschool curricula. A pivotal repertoire to engage in behaviors deemed creative, such as art, storytelling, problem-solving, and the like, is the ability to vary one's responses regardless of the specific repertoire. Researchers have developed methods to produce response variability. How… more

Stimulus Control Effects of Changes in Schedules of Reinforcement

Description: Sometimes, changes in consequences are accompanied by a clear stimulus change explicitly arranged by the experimenter. Other times when new consequences are in effect, there is little or no accompanying stimulus change explicitly arranged by the experimenter. These differences can be seen in the laboratory as multiple (signaled) schedules and mixed (unsignaled) schedules. The current study used college students and a single-subject design to examine the effects of introducing signaled and unsig… more

What Comes Up? Analyzing Patterns of Resurgence using PORTL

Description: The term "resurgence" generally refers to the reappearance of certain behaviors during extinction. Different definitions describe these behaviors as previously reinforced, previously extinguished, or simply previously learned. At first glance, these definitions seem the same. And, researchers have not given much thought to the differences between them. However, these definitions could refer to different initial teaching procedures, and these differences may produce different results during exti… more

The Effects of Instructions on Schedule Sensitivity

Description: There are many situations in which human performances appear insensitive to changing contingencies of reinforcement when compared to nonhuman operant performances. Explanations of these discrepancies have appealed to rule-governance and have provided some evidence that instructions produce these differences by restricting response alternatives as well as functioning as discriminative stimuli for other contingencies. In order to further evaluate these potential functions, a canonical study on ru… more

Equines Do Not Live for Grass Alone: Teaching Equines with Social Interaction

Description: 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… more

Novel Metal-Containing Nanoparticle Composites for Cancer Therapy and Imaging

Description: With all the improvements in cancer treatments, multidrug resistance is still the major challenge in treating cancer. Cells can develop multidrug resistance (MDR) during or after treatment, which will render the cancer cells resistant not only to the chemotherapy drug being used but also to many other structurally- and mechanically-different chemotherapeutics. In the first project, the main focus was on development of drug resistant cell lines by selection with taxol. Gene changes in the L1T2 c… more
