Two prominent brain-based lie-detection methods are ________.

• A. Neuropsychology and neuropathology
• B. SPECT scans CAT scans
• C. Neuroimaging and brain wave analysis
• D. Neurotransmitters and neurochemicals

Answer: (C)

In lie-detection research, two main brain-based approaches are used: neuroimaging and brain wave analysis. Neuroimaging looks at brain activity patterns while a person lies versus tells the truth, using techniques like functional MRI (fMRI) and PET scans. These methods reveal which brain regions light up when deception requires more cognitive control, monitoring, and decision-making, such as parts of the prefrontal cortex and anterior cingulate. The idea is that lying typically imposes greater cognitive load and conflict monitoring, producing distinct activity patterns that researchers can detect. Brain wave analysis, usually done with EEG, examines electrical signals and event-related potentials that occur in the brain in response to stimuli or deception-related processing. Components like the P300 can differ when a person recognizes information tied to a concealed knowledge, providing a physiological signal that may differentiate lies from truths in controlled settings. This category captures the rapid, real-time brain responses associated with deception. Other options don’t fit as well because they either describe fields (neuropsychology, neuropathology), broad imaging modalities that aren’t specifically labeled as lie-detection methods (SPECT, CAT scans), or biochemical factors (neurotransmitters and neurochemicals) rather than the brain activity or electrical signals used to detect deception.
