Which measure of emotion is most invasive?

Question

Quizplus · Accepted Answer

Functional magnetic resonance imaging (fMRI) is the most invasive measure of emotion as it requires the participant to lie down inside a large, noisy machine for an extended period while their brain activity is being monitored. This can be uncomfortable and may cause anxiety for some individuals. In contrast, language-based questionnaires and the Self-Assessment Manikin (SAM) are non-invasive and can be completed relatively quickly, while the Facial Action Coding Scheme (FACS) involves only observation of facial expressions and does not require any physical contact with the participant.
