Predicting Human Performance. VII. Visual Search for Complex Targets.
Abstract
Using available data, search time and stimulus processing rate for a multidmensional target in an array were analysed with respect to number of displayed stimuli and total stimulus information. Other factors also considered were the probability of target detection as a function of number of displayed stimuli, target familiarity, and visual noise. The major findings were that search time decreases and stimulus processing rate increases as the number of dimensions in a multidimensional target increase, and that the rate of processing increases as a function of total stimulus information. A model of total stimulus information which assumes sequential processing of dimensions in order of increasing features or levels was found to fit the data reasonably. (Author)
