idea. A. Thresholds * An Absolute Threshold is the lowest amount of stimulus needed to notice it 50% of the time. * For example‚ you turn down the radio to a point where you only hear the faint sound half the time. Then that loudness (decibel) is your absolute threshold for sound. * Signal detection theory predicts when we will detect weak signals (measured as our ratio of “hits to “false alarm”). * It seeks to understand why people respond differently to the same stimuli‚
