rectangle that is longer and more narrow with a higher frequency than the original with which it was trained. This is called a supernormal stimulus. The fact that the rat is responding more to a 'super' rectangle implies that it is learning a rule. This effect can be applied to human pattern recognition and aesthetic preference. Some artists attempt to capture the very essence of something in order to evoke a direct emotional response. In other words, they try to make a 'super' rectangle to get the viewer to have an enhanced response. To capture the essence of something, an artist amplifies the differences of that object, or what makes it unique, to highlight the essential features and reduce redundant information. This process mimics what the visual areas of the brain have evolved to do and more powerfully activates the same neural mechanisms that were originally activated by the original object. Some artists deliberately exaggerate creative components such as shading, highlights, and illumination to an extent that would never occur in a real image to produce a caricature. These artists may be unconsciously producing heightened activity in the specific areas of the brain in a manner that is not obvious to the conscious mind. A significant portion of the experience of art is not self-consciously reflected upon by audiences, so it is not clear whether the peak-shift thesis has any special explanatory power in understanding the creation and reception of art. Isolation Isolating a single visual cue helps the organism allocate attention to the output of a single module, thereby allowing it to more effectively enjoy the peak shift along the dimensions represented in that module. In other words, there is a need to isolate the desired visual form before that aspect is amplified. This is why an outline drawing or sketch is sometimes more effective as art than an original color photograph. For example, a cartoonist may exaggerate certain facial features which are unique to the character and remove other forms which it shares such as skin tones. This efficiency prevents non-unique features from detracting from the image. This is why one can predict that an outline drawing would be more aesthetically pleasing than a color photograph. The viewers attention is drawn towards this single area allowing one's attention to be focused on this source of information.
