Insider threat represents a significant source of violations of information security. Our previous research using event-related potentials (ERPs) has revealed patterns of neural activity that distinguish ethical decision making from decisions that do not involve an ethical component. In the current study, we sought to gain insight into the locus of the effect of ethical decision making on the posterior N2 component of the ERPs. The ERP data revealed that the N2 was greater in amplitude for control trials relative to ethical violation trials, and time-frequency analyses revealed that this resulted from a reduction in phase-locked activity across trials rather than a decrease in EEG power. These findings may indicate that ethical decision making related to information security is associated with a greater inward focus of attention than is the case for decision making on control trials.
