A chronometric model of the relationship between frontal midline theta functional connectivity and human intelligence.

Individual differences in cognitive control have been suggested to act as a domain-general bottleneck constraining performance variety of ability measures, including but not limited fluid intelligence, working memory capacity, and processing speed. However, owing psychometric problems associated with the measurement individual control, it has challenging empirically test assumption that underlie abilities. In present study, we addressed these issues by analyzing chronometry intelligence-related midfrontal global theta connectivity, which shown reflect functions. We demonstrate sample 98 adults, who completed task while their electroencephalogram was recorded, connectivity during stages higher-order information-processing explained 65% variance intelligence. comparison, task-evoked earlier information related These results suggest more intelligent individuals benefit from an adaptive modulation theta-band synchronization time-course processing. Moreover, they emphasize role interregional goal-directed for processes human intelligence support theoretical accounts propose give rise (PsycInfo Database Record (c) 2021 APA, all rights reserved).
