The perceptual style known as field independence has been defined by various investigators as the ability to perceptually separate an object from within a complex background. This investigation attempts to test this concept in a literal manner by examining the relationship between several established measures of field independence and performance on a real-life visual detection problem. Only one of the instruments used, the Hidden Figures Test, correlated significantly with performance. An added finding was a correlation between performance and general intelligence. Furthermore, interest correlations showed that the instruments used could be divided into two groups, each measuring what appears to be a separate quality of the field independence concept.
