What Is a Major Advantage of Signal-Detection Methods Over Traditional

question 131

Multiple Choice

What is a major advantage of signal-detection methods over traditional ways of measuring thresholds?

• A) Signal-detection methods allow the investigator to distinguish between sensitivity effects and tendencies to respond too conservatively or too liberally.
• B) Signal-detection methods allow the investigator to separate hits and misses from correct negatives and false alarms.
• C) Signal-detection methods allow the investigator to introduce occasional "catch" trials to eliminate response biases.
• D) Signal-detection methods allow the investigator to multiply the effects of sensitivity by the magnitude of the response bias.
