The signal detection theory assumes that a person's absolute threshold for a particular stimulus is influenced by top-down processing, such as expectations, motivations, and experiences. It suggests that our ability to detect a signal among background noise is not solely determined by the strength of the signal but also by the criteria that we set based on subjective factors. Therefore, a person with higher expectations or motivations for detecting a stimulus may have a lower absolute threshold than someone with lower expectations or motivations.
