Final answer:
Brain imaging techniques can provide evidence for correlations between performing tasks and activation of a specific brain region, but they cannot determine cause and effect relationships.
Step-by-step explanation:
One problem with brain imaging techniques is that they can provide evidence for correlations between performing tasks and activation of a specific brain region, but they cannot help us know if one causes the other.
This statement is true. Brain imaging techniques like functional magnetic resonance imaging (fMRI) can show us which areas of the brain are active during certain tasks, but they cannot determine whether the task is causing the activation or if the activation is causing the task.
For example, fMRI can show that a certain brain region is active when a person is reading, but it cannot tell us if the activation in that region is causing the person to read or if reading is causing the activation. Therefore, while brain imaging can provide valuable information about brain activity, it cannot definitively establish cause and effect relationships.
