Abstract
The main experiment reported in this paper investigates the effects of changes in defect rate, the number of different types of fault present, the complexity of items, inspection rate, and the horizontal velocity of items upon inspection performance. An analysis of d' revealed that discriminability significantly decreased as the number of fault types, or the number of subassemblies increased, and there was also a significant interaction between complexity and defect rate. The only other significant effects were due to complexity influencing caution, and response latency.
A second experiment is also briefly described, which illustrates the use of response latencies to obtain TSD data from inspection tasks.
