A non-reflective level of arousal achieves a strong awareness of the stimulus without any figure-ground structure.
Non-reflective Level of Arousal: With a little more energy investment, we become focused more clearly on the stimulus. We do not yet, however, develop a figure or ground structure.
This, for example, would be like listening to the hubbub or background din at a party, where there is an auditory collage of noises such a clinking, murmuring, shuffling, coughing, etc., but not anything that would stand out.
When I was child, I used to listen to boxing on the radio on Friday evenings. The drone of the audience would put me to sleep before the main fight was over so that I never knew who won. Football crowds on TV have done the same thing to me a an adult.
In the visual modality, we would experience a mosaic of shapes, shades textures and colors but no clear figure. I believe we do this also when we are deep in thought.
