Effect of Response Mode on Target Identification.

Abstract

An experiment was conducted to determine the effects of two response modes (immediate versus delayed response) on target identification performance. Ship images were displayed sequentially, in sets of five, on a television monitor simulating infrared imagery. A prebriefed 'target' ship appeared once in each set. 'Immediate' responders designated targets at the time of presentation; 'delayed' responders made a target designation after viewing each set. Observers' target identification performance was assessed as a function of image size (7, 10, and 13 TV lines) and image exposure time (2 and 4 seconds), as well as response mode. No difference in identification performance was found between response modes. Performance was significantly better for 10- and 13-line images than for 7-line images. Exposure time had no significant effect.
