Abstract:

Results obtained by other experimenters have demonstrated relationships between target detection performance and field dependence and between target detection performance and intelligence. This Note reports an attempt to verify this earlier work. During a series of field trials at Green bank, Queensland, soldiers were set the task of detecting stationary targets in dense jungle. Their detection scores were correlated with their scores on tests of field dependence and intelligence. The data failed to support the earlier findings. The detection tasks in this, and in two previous experiments, were similar in that stationary, camouflaged targets were used. However the detection tasks used in the two previous experiments correlated with tests of field dependence and intelligence, but the detection task used in this experiment did not. Research workers have generally assumed that a common factor contributes to performance over a wide variety of detection tasks. A general factor explanation is, however, not tenable for the data of this and other experiments. Research directed at defining factors that contribute to performance on particular detection tasks, and that can be measured independently of those tasks, may be more useful at this stage. than a search for a general target detection factor.
