System, methods, and other embodiments described herein relate to controlling display attributes within a visual interface for enhancing stimuli and responses of a user. In one embodiment, a method includes selecting display attributes related to a first layer of an image and a second layer of the image, and the first layer includes a symbol, the second layer represents a background of the symbol, and the image is associated with an interface to control a component. The method also includes oscillating, at first multiple of a frequency, between first values of the display attributes representing colors that are different for displaying the first layer, and the colors changing by a duty cycle associated with the first multiple of the frequency. The method also includes oscillating, at a second multiple of the frequency, between second values for displaying the second layer in parallel with the first layer until detecting a selection associated with the interface.
