Study Summary
The study is one part of a "bundle" of experiments that constitute Project Three of a National Eye Institute grant. Project Three includes a series of experiments that investigate how changing the input from a simulated AI can affect the decisions made by human observers in a two-alternative forced choice task (like the decision to recall a woman for further examination in mammography). HAICT 7, the experiment described here, investigates how changing prevalence affects human performance when AI is used as a Second Reader.
Primary Outcome
D' (d-prime) is the signal detection theory measure of the level of performance on a task. It is computed by calculating the proportion of true positive responses =(true positive trials)/(true positive + false negative trials) = p(TP) and by calculating the proportion of false positive responses =(false positive trials)/(false positive + true negative trials) = p(FP). These values are transformed into 'z-scores' (for example, using NORMSINV in Excel to calculate the inverse of the standard norma
