Abstract

Title: Tracking The Growth of Evidence in Visual Comparison Tasks
Abstract: Many applied tasks involve a comparison between visual images. For example, the Boston Bombing case was solved primarily through the manual comparison of images of the bombers with faces from other databases. Of course, no two picture or impression are identical, and thus the examiner must make judgments about the likelihood of the two images deriving from the same source. In the present work we collected data from fingerprint examiners when they performed a visual comparison task not unlike a latent print examination. In the first stage we asked examiners to select regions they thought might be diagnostic. In the second stage we showed these regions one at a time and asked for a judgment of whether the two came from the same source or different sources. We fit models based on signal detection theory to summarize the results. We found that, contrary to a model of holistic or configural processing, evidence seems to grow linearly with the number of regions. We also can track the growth of evidence in favor of exclusion or identification, and I'll present data on this point. The design addresses how weak and strong evidence is interpreted and has some surprising results about how weak evidence is evaluated.
