Depressive Feedback Utilization: The Feedback-Related Negativity as an Index of the`Catastrophic Response to Perceived Failure'
… current research examined the impact of negative feedback on event-related potentials associated with error detection and correction in individuals with varying levels of depression. Depression is known to be associated with a number of cognitive effects, including deficits in executive …

Top-down and Bottom-up influences on ACC activation: Evaluation of a proposed model of the feedback-related negativity
The Feedback-Related Negativity (FRN) is thought to reflect the dopaminergic prediction error signal from the subcortical areas to the ACC (i.e., a bottom-up signal). Two studies were conducted in order to test a new model of FRN generation, which includes direct modulating influences of medial PFC …

The Feedback-Related Negativity is a Time-Dependent Brain Mechanism that Facilitates Aversive Learning: Implications for the Reinforcement Learning FRN Hypothesis
… I examined variation in reaction times and feedback-locked cortical activity over time as a function of PE to critically examine theories indicating that PE signals drive time-dependent learning. We recorded EEG while participants completed a novel reinforcement task that varied prediction …

Can I Eat This? Event-Related Potentials are Modulated by Feedback Regarding Edibility
Feedback-related negativity (FRN) is an event-related potential (ERP) component that has been shown to be sensitive to feedback during risk-taking, such that the FRN is larger for negative outcomes. Another ERP wave, the P300, is known to play a role in attentional resource allocation and is …

Behavioral and Psychophysiological Effects of Near-Miss Outcomes in a Game of War
… inter-trial latencies and the presence of the feedback-related negativity (FRN) and P300 event related potentials (ERPs) in a game of war card game. FRN is a negative fronto-central ERP component occurring 200 and 300 ms post-feedback, and P300 is positive centro-parietal ERP component …

A stochastic control framework for the design of observational brain-computer interfaces based on human error potentials
Brain-computer interfaces (BCI) allow human subjects to interact with exogenous systems through neural signals. The goal of this interaction may be to induce behaviors or properties in either the exogenous system or the human subject. In this thesis, we develop a novel framework for designing BCIs …
