Question: 17
2. A man is at a party with his wife. There is loud music in the background and the location is crowded. While listening to the music he hears what he believes to be his wife's laughter and turns around to investigate. The man is exhibiting:
- A. feature detection.
- B. bottom-up processing.
- C. vestibular sense.
- D. signal detection.
Correct Answer: D
Explanation:
The man is discerning a specific noise within a field of many noises. This is the definition of signal detection. In an experimental setup, his response would be considered a hit if his wife was indeed laughing; his response would be considered a false alarm if his wife was not laughing.
