Which deception-detection approach monitors brain activity rather than physiological arousal or verbal responses?

• A. Cognitive-based methods
• B. Arousal-based methods
• C. Brain-based methods
• D. Verbal-content analysis

Answer: (C)

Brain-based deception detection focuses on neural activity directly. It uses imaging or electrophysiological techniques to observe how the brain responds when a person lies, capturing patterns of activation that reflect deception rather than relying on physical arousal signals or what someone says. This directly targets brain processes, which is why it’s the approach that monitors brain activity. Arousal-based methods rely on peripheral signs like skin conductance or heart rate, which show arousal but not brain activity. Verbal-content analysis looks at language and semantic cues rather than brain function. Cognitive-based methods examine mental processes such as cognitive load or reaction time, but they don’t measure brain activity themselves.
