The Neurophysiology Of Intersensory Selective Attention And Task Switching, Jeremy W. Murphy
Dissertations, Theses, and Capstone Projects
Our ability to selectively attend to certain aspects of the world and ignore others is fundamental to our day-to-day lives. The need for selective attention stems from capacity limitations inherent in our perceptual and cognitive processing architecture. Because not every elemental piece of our environment can be fully processed in parallel, the nervous system must prioritize processing. This prioritization is generally referred to as selective attention. Meanwhile, we are faced with a world that is constantly in flux, such that we have to frequently shift our attention from one piece of the environment to another and from one task to …
Role Of Alpha Oscillations In Reweighting Multiple Attributes During Choice, Samuel I. Dunham
Role Of Alpha Oscillations In Reweighting Multiple Attributes During Choice, Samuel I. Dunham
CMC Senior Theses
In our everyday lives, we must often weigh the different attributes of items in order to select the item that best fits our current goals, allowing us to make optimal decisions. Construal Level Theory proposes a psychological mechanism for re-weighting attributes, utilizing selective attention as the process by which we implement self-control. It has been hypothesized that switching attention between attributes is facilitated by the suppression of cortical oscillations over posterior brain regions within the alpha (8-12 Hz) frequency range. To test this idea, we re-examined previously collected whole-brain electroencephalography (EEG) data from a dietary choice experiment in which participants …

Separating The Signal From The Noise In Electrocorticographic (Ecog) Signals : Novel Analytic Methods And Their Application To Experimental And Theoretical Neuroscience, William Grey Coon
Legacy Theses & Dissertations (2009 - 2024)
Measurements are comprised of two parts: signal, that is, the true quantity one wishes to measure, and noise, that is, measurement fluctuations that are unrelated to the true signal.
