The conference has now moved on to the first symposium, which is mostly about basic predictors. Dr Neubauer has taken the Chair:
Neural efficiency as a function of task demands.
Brighter individuals show lower brain activation than less bright individuals when working on the same cognitive tasks. Consequently, the same task is more easy for individuals with higher cognitive ability, but more difficult for less intelligent individuals. The new results suggest that neural efficiency reflects an ability-dependent adaption of brain activation to task demands. According to the refined definition, neural efficiency describes the phenomenon that more intelligent individuals show lower brain activity than less intelligent ones only when working on cognitive tasks with a comparable sample-based difficulty. It looks as if each person works out the difficulty level for them of each task, and then has to devote less brain activation to the tasks they find manageable. Interestingly, it is still the case that bright people use less of their brain when doing difficult tasks.
This study is trying to find out why high-achieving students sometimes take longer to solve difficult nonverbal cognitive task items.
