Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris May 2017

Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris

Thesis Projects

Feather plucking (FP) is a maladaptive behavior observed in captive avian species. This self-injurious behavior results in damage to and removal of feathers and skin tissue, resulting in animal welfare and financial consequences. The etiology and maintenance of FP have been hypothesized through medical and environmental processes, yet a definitive solution has not been found. The current study investigated the environmental variables maintaining the FP of a Black Vulture (Coragyps atratus), as well as evaluated a function-based treatment for this behavior. The behavior was found to be maintained by positive reinforcement in the form of contingent attention. Treatment …


Evaluating Preference Stability Among Individuals With Alzheimer’S Disease, Sabrine Maali Apr 2017

Evaluating Preference Stability Among Individuals With Alzheimer’S Disease, Sabrine Maali

Thesis Projects

In the behavior-analytic field, preference assessments are conducted to determine specific items to use as reinforcers to reduce aberrant behavior as well as increase appropriate behavior. We examined the consistency of preference-assessments results among individuals with Alzheimer’s Disease (AD) to ensure effective reinforcers are used in behavioral interventions. Specifically, we examined if identified reinforcers remained consistent for individuals with AD throughout the study or if preferences shifted. The experimental procedure consisted of a series of multiple-stimulus preference assessments without replacement (MSWO); data were analyzed for preference shifts. Results showed variability with one individual’s preferences, whereas the other individual’s preferences remained …
