Figure 3. Location effect represented by torque analysis in the visual operant paradigm.

Figure 3

(A–C) Obvious location dependence in the rDTabs between safe quadrants and dangerous quadrants. (A) Box plots of rDTabs for color, p = 0.0022. (B) Box plots of rDTabs for COG, p  = 0.0189. (C) Box plots of rDTabs for contour orientation, p = 0.2243. (D–F) Significant location dependence in the rDFS between safe quadrants and dangerous quadrants. (J) Box plots of rDFS for color, p = 4.9328×10−4. (K) Box plots of rDFS for COG, p = 0.0023. (L) Box plots of rDFS for contour orientation, p = 0.0257. Patterns are presented as inserts. The data are shown by box plot; the p values were calculated by the Kruskal-Wallis test; the red crosses represent outliers; the y-axes of certain charts are truncated for compactness.
