1. Given that these bags are fairly easy (they wouldn't release the hard ones to be published), what would be the most difficult part of this task for a trained screener? 2. It has been proposed that screeners should be specialized in finding specific contraband objects and that a team of people should be reviewing the image in order to reduce dual-target costs. Now that you have experienced the task, what would be the advantages to the screener if this proposal was implemented? What would be the advantages to the traveling public? 3. One of the major factors involved in this search task involves signal detection theory (searching through clutter [noise] to find contraband [signal]). How would specialized search affect the d-prime and criterion values in this signal detection task
