Functional Magnetic Resonance Imaging (fMRI) is considered a manipulation technique because subjects undergo at least two different treatments during the experiment in order to capture relative increases in activation arising from one of the treatments.

This statement is TRUE.

Explanation:

Functional Magnetic Resonance Imaging (fMRI) measures brain activity in blood flow.  The blood flow concentrates or increases in the neural zone that is being used or activated.

This technique can be afected by certain factors such as noise from the scanner, also it can be afected by brain activity from sensations or thoughts. This is the reason why the subjects go through at least two different treatments in order to determine relative increases in the activation of each treatment.
