results reveal negative thoughts or feelings?
No. Neither the PSA nor the TA is a test of personality. As such neither measures psychological health or pathology. It is best to think of the PSA as a sorter. By having you rate descriptive adjectives it sorts out which Perceptual Style best fits your self-description and, by inference, what your true innate Perceptual Style is. Think of the TA as a point-in-time measure of your awareness and use of Your Talent Advantage. It reveals which of eighteen Natural Action Capacities (NACs) you most often use. Some of these NACs are naturally supported by your Perceptual Style others are not. The TA tells you how consciously you are using those NACs that are supported by your Perceptual Style.
