When you go to the museum remember the following

Ramachandran's The eight laws of artistic experience

1 The ‘peak shift principle’ makes exaggerated elements attractive

2 Isolating a single cue helps to focus attention

3 Perceptual grouping makes objects stand out from background

4 Contrast is reinforcing

5 Perceptual ‘problem solving’ is also reinforcing

6 Unique vantage points are suspect

7 Visual ‘puns’ or metaphors enhance art

8 Symmetry is attractive
