What task did participants perform after being injected with the glucose tracer?

Simple Reaction Time Task
Continuous Performance Task
Memory Recall Task
Logical Reasoning Task

The correct answer is: Continuous Performance Task

The Continuous Performance Task is the correct option because it is designed to assess sustained attention and the ability to control high-level cognitive functions, which can be influenced by glucose levels in the brain. After being injected with a glucose tracer, participants are likely to engage in tasks that help researchers understand how glucose consumption affects cognitive processes. In studies focusing on glucose administration, researchers often examine how cognitive performance can be enhanced due to energy provided by glucose, making a Continuous Performance Task particularly relevant. This kind of task requires sustained attention over time, which is pertinent when exploring the effects of glucose on cognitive functioning. The other tasks listed, while they involve different aspects of cognitive processing, do not specifically focus on sustained attention or cognitive control in the same way that a Continuous Performance Task does. Therefore, they are less suitable for examining the direct impact of glucose on cognitive functions related to attention.
