New research in political psychology increasingly suggests that political orientation may have a psychological and biological component. We seek to contribute to this research by exploring the role of inhibition in political orientation. Our project has two stages. First, we look for correlation between self-reported measures of political orientation and inhibitory behavioral motivation, using Gray’s theory of the Behavioral Inhibition System (BIS). Second, we propose a behavioral task to corroborate our survey findings and advance beyond selfreported measures. The Go/No-Go task habituates participants into a frequent “Go” response but then infrequently introduces an unpredictable “No-Go” signal, requiring participants to quickly inhibit the habituated “Go” response. We will record behavioral data as well as electroencephalography, which is a measure of electrical signals from the brain. Using a stratified sample of strong liberals, strong conservatives, and consistent moderates we expect to find behavioral and neurocognitive differences between these three groups during the Go/No-Go task. This study builds on Amodio, Jost, Master, and Yee (2007), but includes multiple measures of political orientations and uses a non-student sample.
