Signal detection theory ap psychology.
Signal Detection Theory (SDT) is a framework used in psychology and neuroscience to understand how organisms discriminate between signal and noise within a variety of contexts. SDT assumes that the detection of stimuli in an environment is influenced by both sensory and decision-making processes.

According to the signal detection theory, various psychological factors, including Mark’s level of attention, motivation, and expectations, will impact whether or not he detects the incoming text message or not. There are four possible outcomes for Mark in this situation based on the signal detection theory described in the Table below.
