Intelligence, Task Difficulty, and the Regulation of Activity in the Brain’s Default Mode Network
Ulrike Basten, Rebecca Anik Rammensee, Rebekka Weygandt et al. preprint
This study investigates intelligence-related differences in the adjustment of brain activity and connectivity to varying cognitive demands, testing for a moderation of an association between intelligence and neural efficiency by task difficulty. In 72 young adults (34 female, 38 male), fMRI brain activity changes during a decision-making task with five levels of difficulty were related to...
