However, people who are synaesthetic create additional perceptions of the rose that are usually inaccurate. 1 y signal detection theory concerned with the factors that influence sensory judgments. This decision criterion can change from time to time depending on fatigue, expectation, and the potential significance of the stimulus: single detection shows us that perception is, in part, a decision. Increased rewards for noticing stimuli often results in lower detection thresholds. If you lift a weight of 500 grams, the other weight must be at least 510 grams for a comparison to be made (1/50= 10/500) the smaller the fraction = the higher the sensitivity. e. g. monotonous background sounds are largely unheard. e. g. the feel of a watch on our hand eventually decreases from our awareness.
