The homogeneity effect on figure/ground perception in infancy

We examined whether the homogeneity of the two profiles of Rubin's goblet affects figure/ground perception in infants. We modified the two profiles of Rubin's goblet in order to compare figure/ground perception under four test patterns: (1) two profiles painted with horizontal lines (horizontal-line condition), (2) two profiles painted middle gray (uni-color condition), (3) one profile painted light gray and the other dark gray (two-color condition), and (4) a goblet painted with concentric circles (concentric-circles condition). In the horizontal-line condition the homogeneity of the profile was strengthened, and in the two-color condition the homogeneity of the profile was weakened compared to the uni-color condition, which was an original Rubin's goblet. In the concentric-circles condition the homogeneity of the reversed areas of the horizontal-line were strengthened.     

Goblet Words and Indeterminacy：A Writing Style that Is Free of Commitment

The Zhuangzi is a collection of ancient Chinese anecdotes and fables that serves as a foundational Daoist text. The style in which it is written is significant because it obscures rather than reveals the text’s philosophic positions. If the text cannot be translated into plain language while preserving its content, as the Mozi or the Mencius generally can be, then the writing style is not merely rhetorical. The style is itself indispensable to the content. In this study, I analyse a linguistic device mentioned in the Zhuangzi and use it to reflect the text’s writing style—namely, “goblet words” (zhi yan 巵言). I argue that various logical forms of goblet words defy the act of fixing a definite answer in any conceptual distinction or disputation. The forms, which include dilemmatic questions, oxymora and double denial, all serve to preserve indeterminacy. Reading goblet words may affect readers by making them more open-minded towards distinctions. However, readers cannot ascertain that the text’s authors produced this effect intentionally. Therefore, the text may cause readers to be open-minded while the authors remain free of commitment.
