47        - fillets meeting with psa and humppake
48            - some ideas to think about:
49                    - show the nodes (without connections) before
50                      showing the full graph in each trial
51                      --> search time eliminated
52                    - color all nodes differently and interpolate
53                      the color over the connections -->
54                      should be even less ambiguous
55                      (probably not usable for showing the
56                      superiority of fillets)
57            - conclusion:
58                    - experiments first
59            
60        - read the book "Robert M. Boynton: Human Color Vision,
61          New York: Holt, Rinehart and Winston, 1979." Notes:
62            - sensitivity regulation for lightness is well known:
63              the size of pupil, pigment bleaching, and receptor
64              sensitivity adapt the sensitivity
65            - however, chroma sensitivity as a function of chroma range
66              is not directly considered in the book
67            - contours play a crucial role in color vision:
68              colors are averaged over regions separated by contours
69            - B cones do not participate in contour perception
70              (there are very few B cones in the fovea)
71            - colors whose R-G and R+G responses are identical
72              are discriminated better if a small gap is inserted
73              between the fields so as to enable contour perception
74

77      - tried "is there one or two connected componens?" task      - tried "is there one or two connected componens?" task
78          - too hard for >12 nodes --> cannot measure scaling          - too hard for >12 nodes --> cannot measure scaling
