The objective of this research is to evaluate the effect of providing online feedback, process, and process plus performance on visual search performance for a printed circuit board inspection task. A training aid was developed that provided process and process plus performance feedback and enabled a comparison between the two feedback strategies. Two search strategies—search by area and search by component—were adopted to complete the task, and their sensitivity to the type of feedback and search performance was evaluated. Providing process plus performance feedback helped in improving speed and accuracy, whereas area search strategy proved beneficial in improving search speed for both feedback strategies. Graphical feedback on the component location helped in locating more component defects than area defects. © 2003 Wiley Periodicals, Inc. Hum Factors Man 13: 115–136, 2003.
