How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation. 相似文献

The Diana (Diana v. State Board of Education, Note 1) and the Larry P. (Larry P. v. Riles, Note 2) litigations led to decertification of thousands of California EMR students and their return to the regular program. Allegations, including those of biased testing, went largely uncontested in order that change in special education could result from court mandate, but the allegations left the psychologists in a libeled state. A study of cumulative records and psychologists files in 12 representative districts permitted a comparison of the EMR placement of those later decertified (D) with matched nondecertified (EMR). Other than a small mean difference in IQ at placement, nothing was found to support various allegations. Records showed no systematic differences betweeen D and EMR groups in pre-EMR reasons for referral nor in teacher marks, discnfirming beliefs in referral of higher functioning students for deportment rather than for academic failure. Districts permitted a mean of at least two years in regular placement before assessment, attesting to class failure rather than IQ as the initial and necessary basis for EMR identification (no D-EMR difference in this either). The data permit a conclusion that the work of the school psychologists in the EMR placement was professionally competent, given the guidelines in effect at the time. 相似文献

A preparation for the experimental analysis of cigarette smoking is described in detail. The preparation permits the intensive study of cigarette smoking in individual subjects under controlled laboratory conditions. A variety of behavioral and physiological measures used include rate and pattern of puffing, duration of each puff, time spent smoking cigarettes, expired air carbon monoxide levels, cigarette butt weights, and subjective rating scales of various aspects of smoking. The preparation is reliable and permits relatively unobtrusive monitoring of smoking performance. Cigarette smoking occurs in orderly patterns, within subjects; it varies as a function of number of cigarettes provided and hours of smoking deprivation. 相似文献
