Abstract
Two studies were carried out to investigate the strategies and information used in classifying complex non-speech sounds of the type processed by passive sonar operators. Current pattern recognition models hypothesize that context and previous experience play an important role in the recognition of visual and auditory patterns. In addition, sonar operators are often provided with tools to assist in the analysis of visual and auditory sonar patterns. In the present study, observers learned to classify a set of 20 targets along two dimensions - type and speed. They were then tested on an extended target set composed of thirty targets. Observers were provided with knowledge about the original target set through feedback and descriptions of the target types, and a tool for analysing the speed. The effects of the analysis tool, information about the target set and experience with the training set on recognition performance were evaluated. TRUNCATED
