2008 U.S. Presidential Election: Persuasive Youtube Interactions About War, Health Care, And The Economy, Lindsey Zimmerman
2008 U.S. Presidential Election: Persuasive Youtube Interactions About War, Health Care, And The Economy, Lindsey Zimmerman
Psychology Theses
Persuasive appeals posted to United States presidential candidates’ YouTube videos were coded using a grounded theory mixed-methods design. 37,562 comments about education, energy, Iraq, health care, the economy, and the presidential debates were randomly collected by date and time for three studies using coding analysis: pilot, presidential primaries, and the presidential election. Seven argument types were identified and theoretically refined according to dual process models of persuasion: reason-based, candidate-based, emotion-based, endorsements, enthusiasmheuristic, other-interest and self-interest. Theoretical comparisons and hypothesis testing of argument types were conducted by issue and election event. Consistent with impression involvement, reason-based appeals were more frequent during …
Frontal Alpha And Beta Eeg Power Asymmetry And Iowa Gambling Task Performance, Richard Toby Amoss
Frontal Alpha And Beta Eeg Power Asymmetry And Iowa Gambling Task Performance, Richard Toby Amoss
Psychology Theses
Frontal electroencephalographic (EEG) alpha (α) asymmetry may index the activation of lateralized affect and motivation systems in humans. Resting EEG activation was measured and its relationship to Iowa gambling task (IGT) performance was evaluated. No effects were found for α power asymmetry. However, beta (β) power asymmetry, an alternative measure of resting EEG activation, was associated with the number of risky decisions made in the early portion of the task. Additionally, IGT deck selection patterns suggest there are at least three distinct performance styles in healthy individuals. Interestingly, β power asymmetry contradicts performance predictions based on accepted frontal asymmetry affect …
