Double reading reduces miss errors in low prevalence search.

Low prevalence studies show that people miss a large proportion of targets if they appear rarely. This finding has implications for real-world tasks, such as mammography, where it is important to detect infrequently appearing cancers. We examined whether having search in pairs double reading procedure reduces errors low compared with when participants the displays alone. In Experiment 1 searched mass laboratory mammogram task. Participants either same display together (in room) or independently separate rooms). 2 further manipulated order so paired read mammograms different orders. The results showed that, although there was no effect order, led substantial reduction single conditions. Furthermore, reason improvement differed across environments: When shared environment (i.e., occurred due an increase sensitivity; however, rooms change response bias.
