Outline of Final Research Achievements

Achieving sustained focused attention of an individual on a task at hand has been important in various fields. However, excessive focused attention may cause perceptual suppression to other events, which in turn could lead to various near-miss incidences. The current study investigated the possibility that the frontal midline theta (Fm θ) activity associated with focused attention is also related to perceptual suppression that leads to errors.
This experiment used a video game with English alphabet letters randomly presented around the screen one at a time. Statistically significant positive correlation was observed between the occurrence of Fm θ and the ratio of correctly recognized letters. Fm θ occurrence was negatively correlated with a greater self-reported frequency of near-miss incidences. However, an analysis of brain wave at 200-ms prior to an English letter presentation revealed no difference in Fm θ occurrence between correctly and incorrectly recognized letters.
