It is based on the idea that individuals may pick up on meaningful information, known as “signals,” from noisy and ambiguous stimuli. Psychologists use signal detection theory to evaluate how accurately participants are able to recognize faint stimuli under a variety of different conditions. In a typical experiment the participants are asked to indicate if the stimulus was either present or absent, and the researcher assesses if the decision was correct. Radio waves are detected using electrical circuits that receive these electromagnetic signals in an antenna, and then the radio frequencies are modulated through capacitors before ...
