Production and comprehension have long been viewed as inseparable components of language. The study of vision, by contrast, has centered almost exclusively on comprehension. Here we investigate drawing—the most basic form of visual production. How do we convey concepts in visual form, and how does refining this skill, in turn, affect recognition? We developed an online platform for collecting large amounts of drawing and recognition data, and applied a deep convolutional neural network model of visual cortex trained only on natural (...) images to explore the hypothesis that drawing recruits the same abstract feature representations that support natural visual object recognition. Consistent with this hypothesis, higher layers of this model captured the abstract features of both drawings and natural images most important for recognition, and people learning to produce more recognizable drawings of objects exhibited enhanced recognition of those objects. These findings could explain why drawing is so effective for communicating visual concepts, they suggest novel approaches for evaluating and refining conceptual knowledge, and they highlight the potential of deep networks for understanding human learning.

Recent data indicate that under a specific posthypnotic suggestion to circumvent reading, highly suggestible subjects successfully eliminated the Stroop interference effect. The present study examined whether an optical explanation could account for this finding. Using cyclopentolate hydrochloride eye drops to pharmacologically prevent visual accommodation in all subjects, behavioral Stroop data were collected from six highly hypnotizables and six less suggestibles using an optical setup that guaranteed either sharply focused or blurred vision. The highly suggestibles performed the Stroop task when naturally (...) vigilant, under posthypnotic suggestion not to read, and while visually blurred; the less suggestibles ran naturally vigilant, while looking away, and while visually blurred. Although visual accommodation was precluded for all subjects, posthypnotic suggestion effectively eliminated Stroop interference and was comparable to looking away in controls. These data strengthen the view that Stroop interference is neither robust nor inevitable and support the hypothesis that posthypnotic suggestion may exert a top-down influence on neural processing.

This book is a collection of articles on different aspects of university education in China since the late nineteenth century, addressing how far the ideal of modern university education, which has gradually been developed in the West since the age of European Enlightenment, was adopted or transformed by Chinese universities.

Alternative theories to quantum mechanics motivate important fundamental tests of our understanding and descriptions of the smallest physical systems. Here, using spontaneous parametric downconversion as a heralded single-photon source, we place experimental limits on a class of alternative theories, consisting of classical field theories which result in power-dependent normalized correlation functions. In addition, we compare our results with standard quantum mechanical interpretations of our spontaneous parametric downconversion source over an order of magnitude in intensity. Our data match the quantum mechanical (...) expectations, and do not show a statistically significant dependence on power, limiting quantum mechanics alternatives which require power-dependent autocorrelation functions.

"The K'ung-ts'ung-tzu (The K'ung Family Masters Anthology) is a collection of writings, most of them discourses, that narrate the lives and scholarly activities of one lineage of Confucius' family, beginning with the Warring States period, and continuing with the establishment of the Ch'in dynasty and the succeeding Han dynasty. The book is divided into three parts. The first, introductory part deals with the Confucian character and literary mood of the K'ung-ts'ung-tzu. It embeds the philosophical position of the text within the (...) Confucian tradition; it discusses the varied content of the text as a whole, and characterizes the gloomy mood that prevails in it. The second part consists of an annotated translation of chapters 15-23 of the text. The third part is a computational reconstruction of the K'ung-ts'ung-tzu's eleventh chapter, a concise dictionary entitled Hsiao Erh-ya."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

In analyzing evidence indicating that K'ung-ts'ung-tzu was a forgery, Yoav Ariel questions current views of the Confucian school in the time between the Sage's death in the fifth century B.C. and the emergence in the eleventh century of Neo-Confucianism. The text, traditionally ascribed to a descendant of Confucius, K'ung Fu, provides a setting for a series of philosophical debates between K'ung family members and representatives of such non-Confucian schools as Legalism, Mohism, and the School of Names. However, finding that this (...) text was probably fabricated by the controversial Confucian master, Wang Su, Ariel explains how it sheds light on the third-century philosophical milieu: Confucianism then is seen to have been not only Taoistically metaphysical, individualistic, and escapist, but also aggressive in advocating early Confucian values. The first part of Ariel's book deals with the general characteristics, history, dating, authenticity, and authorship of the text. The second part is a fully annotated and analyzed translation of the first of the two traditional volumes that constitute the K'ung-ts'ung-tzu. Originally published in 1989. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
