Diagnostic Judgment as a Function of the Pre-Processing of Evidence.
Abstract
Two experiments were conducted to determine how, the quality of a human judgment (in this case, military threat diagnosis) is affected by various levels of pre-processing applied to the raw predictive events when such processing is carried out by the human and by a machine aid. The subject was required to estimate the threat of attack on the friendly position (criterion) posed by levels of activity observed in various enemy positions (cues). These enemy positions differed in the degree of potential threat that they posed. Overall threat judgments were made under conditions in which a prior overt estimate of position activity levels was or was not required. Machine-aiding conditions were as follows: (1) no aiding, where the subject simply observed raw events in real time (Experiment 2), (2) automatic (Experiment 1 & 2) or self (Experiment 1) tabulation of events, and (3) automatic computation of events (Experiment 2). Finally, the rate of event occurrences was manipulated (Experiment 2).
