Effort-Related Choice Behavior Is Affected By Pharmacological Manipulations Associated With Depression: The Effects Of Tetrabenazine, Megan Huizenga
Effort-Related Choice Behavior Is Affected By Pharmacological Manipulations Associated With Depression: The Effects Of Tetrabenazine, Megan Huizenga
Honors Scholar Theses
In humans, psychiatric symptoms such as anergia and psychomotor retardation reflect pathologies in behavioral activation. These motivational symptoms are fundamental aspects of depression and other disorders. Drugs such as reserpine and tetrabenazine deplete monoamines, including dopamine, and induce depressive like behaviors in humans. Our results indicate that administration of low doses of tetrabenazine can alter effort-related choice behavior, biasing animals towards low effort alternatives. These findings may be related to the ability of monoamine depleting agents such as tetrabenazine to blunt behavioral activation and induce psychomotor retardation, anergia and fatigue in humans, and this research could be useful for the …
Habituation Effect In Attention Modification Training For Obsessive-Compulsive Disorder, Olivia E. Bogucki
Habituation Effect In Attention Modification Training For Obsessive-Compulsive Disorder, Olivia E. Bogucki
Honors Scholar Theses
Attention biases influence the type of information that captures an individual’s attention. Cognitive theories of obsessive-compulsive disorder (OCD) state that attention biases cause an increased amount of attention to personally relevant threatening information. Previous studies support this connection, and have examined attention modification training (AMT) as a means to direct attention away from threatening information for various anxiety disorders, including OCD. Results show that attention biases toward threatening information decrease during a single training session of AMT, which may be a result of habituation to threat. However, there is a lack of longitudinal data investigating the number of AMT sessions …
Longitudinal Changes In Pronoun Reversals In Children With Autism Spectrum Disorder And Typically Developing Children, Michelle Cheng
Longitudinal Changes In Pronoun Reversals In Children With Autism Spectrum Disorder And Typically Developing Children, Michelle Cheng
Honors Scholar Theses
Pronoun reversals occur when a pronoun is incorrectly mapped to the wrong referent. For example, when a child says, “You eat the cookie!” and intended to state that he is eating a cookie. Children with Autism Spectrum Disorder, ASD, are known to be frequent reversers, but their development of these reversals; for example, incidence rate and endpoint, is still unknown. In this study, children interacted with their mothers in a 30-minute play session and their spontaneous pronoun usage were coded for the perspective of the pronoun, type of reversal, and case errors. Children with ASD to their typically developing (TD) …
