彫刻・服装・絵画など芸術的パターンの視覚走査メカニズムを解明する第一歩として、Shoichi Ida(1994)のDescended Triangle(下降する三角形)である倒立三角形をデザインしたケネス・ノーランドの"第17段階"(1964)の大と小を5分間ずつWistarラットに提示したところ、常に右辺である右上がりの「右斜線」を視覚走査することが判明した。左斜線は、決して視覚走査されることがない。本論文の結果も、"心は、何も書かれていない板(tabula rasa)である"としたLocke(1689)の主張に反対しているLeibnitz(1703,1765)の考え方が正しいことを実証している(岡崎・三谷,2001;三谷,2002;三谷,2003a)

Research was done on tea infusions after removing coloring ingredients, such as teaflavines, by Polyvinylpolypyrrolidone (PVPP). Turbidity formation of PVPP treated infusions was formed though it was low in comparison with untreated PVPP infusions, but the precipitate of the small globular form wasn't recognized. Octahedron forms with sharp corners were recognized when tea infusions were treated with PVPP as well as when they weren't. When the concentration of calcium was increased, an octahedron could lose its corners. It was reported that two types of the precipitation of the small globular form and of calcium oxalates are mixed in the tea infusions which are infused with the water containing a little calcium.
