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.
Signal-Detection Methods
Statistical and methodological techniques used to determine the ability to differentiate between information-bearing patterns and random patterns that distract from the information.
Thresholds
Points or levels at which something starts or changes, often used in context with physiological or psychological responses.
Sensitivity Effects
The impacts on outcomes in a study due to variations in how sensitive measurements or instruments are to changes in the independent variable.
