Abstract

The development of new array-based facial composite systems requires a new type of interaction between witness and system, relying more on recognition and holistic processing than on the recall and featural processing used in older systems. Although this development seems to be an improvement in terms of what we know of how faces are encoded, it is necessary to determine whether witnesses both want and benefit from this new interface. A series of studies was conducted to determine whether array-based systems do indeed make the most of witness cognition and memory.
