Figure 4.
A color matrix plot depicting the extent to which color patches of X foreground color and Y border color differ from those of Y foreground and X border colors, differ in terms of patch to taste association differences (2 × 2 χ2 test value) to the four basic tastes. The horizontal distance between each XY pair reflects this difference. For example, at the top of the figure are the whiteBlack and blackWhite patches which are the most horizontally separated, and thus, most differing in terms of how participants assigned each patch to each of the basic tastes. Space permitting, the actual percentage tastes-word associations to each word have been plotted between each XY pair, by means of accumulative bar plots (the boxes of ascending lightness in each bar reflect, respectively, the tastes of bitter, salty, sour, sweet); the chart closest to a given patch reflects that patch’s % taste associations. XY pairs consisting of more than one color that statistically differ in terms of their degree of difference have a white star inserted directly between them. Note that the eight single color patches at the bottom of the figure have been added for completeness, and also to make available to the reader, how each was assigned to each of the individual colors.
