The Role Of The Amygdala, Retrosplenial Cortex, And Medial Prefrontal Cortex In Trace Fear Extinction And Reconsolidation, Janine Lynn Kwapis
Theses and Dissertations
A wealth of research has outlined the neural circuits responsible for the consolidation, reconsolidation, and extinction of standard "delay" fear conditioning, in which awareness is not required for learning. Far less is understood about the neural circuit supporting more complex, explicit associations. "Trace" fear conditioning is considered to be a rodent model of explicit fear because it relies on the cortex and hippocampus and requires explicit contingency awareness in humans for successful acquisition. In the current set of studies, we aimed to better characterize the neural circuit supporting the consolidation, reconsolidation, and extinction of trace fear in order to better …
Discrimination Trials To Influence Self-Awareness, Kerin A. Weingarten
Discrimination Trials To Influence Self-Awareness, Kerin A. Weingarten
Theses and Dissertations
Humans often use terms and concepts that include self- as prefix in an effort to explain their behavior (e.g., self-awareness, self-control) (Goldiamond, 1959, 1962, 1965, 1966; Nisbett & Wilson, 1977). Although there are many ways to interpret such terms, they all seem to involve circumstances in which individuals' own prior behavior is discriminative for their subsequent behavior. Behavior under the discriminative control of other behavior may be a kind of self-report (Skinner, 1957). The concepts of self-awareness and self-report can be studied as a behavioral process, without mentalistic inference. In the present research, pigeons were trained in a compound, discrete-trial …
