1.The absolute threshold is BEST described as the:A)minimum amount of energy in a sensory stimulus detected 50% of the time.B)absolute minimum amount of energy needed for a sensory stimulus to be detected.C)absolute maximum amount of energy needed for a sensory stimulus to be subliminally detected.D)maximum amount of energy in a sensory stimulus detected 100% of the time.
2.Signal detection theory is based on:
3.According to Weber's law, the constant fraction for loudness of tones is 1/20. If the difference threshold is 3 decibels, what standard stimulus is being used?
4.According to Stevens's power law, which type of sensory judgment produces perceived magnitudes CLOSEST to the actual physical magnitudes?
