B. Signal-detection theory: theory which suggests how individuals are able to detect a minimal stimulus (signal) among other background stimuli (noise). This may influence how individuals make a decision in a specific situation. C. Receptor sensitivity is subject to change. 1. Sensory adaptation: a decline in receptor activity when stimuliSignal detection theory predicts how and when we detect the presence of a faint stimulus (signal) amidst background stimulation (noise). Signal detection theory assumes that there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and alertness.
