Which example demonstrates a potential misuse of brain imaging in psychology?

• A. Inferring a mental state solely from a single brain region's activation.
• B. Correlating HRV with performance.
• C. Measuring reaction time to a stimulus.
• D. Recording EEG for sleep stages.

Answer: (A)

This item tests the caution needed when interpreting brain imaging data: inferring a specific mental state from activation in a single brain region. In reality, brain functions arise from networks and distributed activity, and many processes can engage the same area. Jumping from the activation of one spot to declaring a particular thought or state is a misuse of the data because it overreaches beyond what imaging can support. The major pitfall is reverse inference—assuming that because a region is active, a particular mental state must be happening. The other options describe legitimate uses or measures that don’t involve drawing a mental-state conclusion from a single brain region. Heart-rate variability linked to performance reflects a physiological measure, not brain-imaging interpretation. Measuring how quickly someone responds is a behavioral metric. Recording EEG to classify sleep stages is a standard, appropriate use of EEG data.
