An Animal Model Of Flashbulb Memory: Insights Into The Time-Dependent Mechanisms Of Memory Enhancement, Laura Ashley Bullard
An Animal Model Of Flashbulb Memory: Insights Into The Time-Dependent Mechanisms Of Memory Enhancement, Laura Ashley Bullard
USF Tampa Graduate Theses and Dissertations
The vivid memory of an emotional event, as well as memory for incidental details associated with the arousing event, has been referred to collectively as a “flashbulb memory”. An important aspect of flashbulb memory in people is that an emotional event enhances memory of contextual details, such as the weather, or clothes one was wearing at the time of the event. Therefore, an emotional event not only produces a detailed memory of the event, itself, but also enhances memory for contextual details that would otherwise not be remembered. The first goal of this work is to describe the development of …
Predator-Based Fear Conditioning: A Novel Approach To The Study Of The Neurobiology Of Memory, Joshua D. Halonen
Predator-Based Fear Conditioning: A Novel Approach To The Study Of The Neurobiology Of Memory, Joshua D. Halonen
USF Tampa Graduate Theses and Dissertations
This series of experiments developed novel paradigms involving the integration of conventional and ethologically relevant forms of reinforcement in the study of fear conditioning in rats. Experiment 1 compared the effects of foot shock, immobilization and predator exposure, alone and in combination, on the expression of conditioned fear memory and extinction. The combination of all 3 reinforcers produced a significantly stronger fear memory and greater resistance to extinction, compared to when each reinforcer was administered alone. Furthermore, whereas conditioning with foot shock, alone, resulted in rapid extinction of the fear memory, the combination of immobilization and cat exposure, or all …
