Answer 1

The false statement is about the use of a galvanometer to assess emotional arousal. The other statements about mechanical recording devices are true.

Step-by-step explanation:

The false statement about mechanical recording devices is b. The galvanometer is used to assess the emotional arousal induced by exposure to specific advertising copy. A galvanometer is actually used to measure the flow of electric current. It is not specifically designed to assess emotional arousal. The other statements are true: a. The people meter provides information about TV shows watched, c. Response latency measures the time taken to answer a question, d. Voice-pitch analysis examines changes in voice frequency due to emotional arousal, and e. Optical scanners measure eye movement over a stimulus.
