Partly in order to facilitate research on the relation between some standard psychological variables, we gathered normative data on 500 proverbs sampled from theOxford Dictionary of English Proverbs (Wilson, 1970). The scales for which we gathered data are imagery, concreteness, goodness , and familiarity. These norms may be of value to researchers who wish to sample linguistic units larger than the word from a set that contains an extensive number of unfamiliar and familiar items. To illustrate the possible uses to which these data may be put, we presented a causal model of the relation between the four variables mentioned above. 相似文献

To answer questions raised about the accuracy of temporal intervals used to produce perception of apparent motion, interstimulus intervals generated by a computer were measured using physical and psychophysical procedures. Calibration of such devices was assumed initially to be routine but search of the literature indicated that calibration has been ignored in studies of motion and masking. Direct/physical methods of calibration proved unfeasible for assessing the accuracy of a computer programmed through "poke" procedures because signals for temporal intervals could not be differentiated from the output controlled by the machine's "hardwired" program. The results of psychophysical measurement of temporal intervals indicated that, on the average, differences, "constant errors" between expected/programmed intervals and matches of those intervals generally were less than six milliseconds. 相似文献

Data in the form of zero-one matrices where conditioning on the marginals is relevant arise in diverse fields such as social networks and ecology; directed graphs constitute an important special case. An algorithm is given for the complete enumeration of the family of all zero-one matrices with given marginals and with a prespecified set of cells with structural zero entries. Complete enumeration is computationally feasible only for relatively small matrices. Therefore, a more useable Monte Carlo simulation method for the uniform distribution over this family is given, based on unequal probability sampling and ratio estimation. This method is applied to testing reciprocity of choices in social networks.The author wishes to thank Cajo ter Braak and John Birks for pointing out the relevance of this subject for ecology; and also Albert Verbeek and Ivo Molenaar, a referee, the Editor, and the Associate Editor for their comments. An earlier version of this paper was presented at the Stockholm Conference on Random Graphs and Applications (April 25–27, 1989), organized with financial support from the Swedish Council of Research in the Humanities and the Social Sciences. 相似文献

The primary goal of ethics consultation should be to provide effective assistance to patients and families in obtaining care that is duly responsive to their rights and their needs. The consultation reported by Mark Bliton fails in this regard because it never ascertains why the consultation was called; makes little attempt to ascertain the motives of those involved; avoids exploration of the ethical concerns of family, attending or staff; makes no connection with institutional policies or practices; uncritically adopts and serves the medical treatment ethos; and substitutes fellowfeeling for compassionate action. 相似文献

Few published reports exist on the appropriateness of curriculum-based measurement (CBM) procedures for literature-based reading programs. The purpose of this paper is to describe a preliminary study of the development and psychometric integrity of CBM norms for literature-based reading using children's literature books. During the 1993–1994 and 1994–1995 school years, the reading achievement of 403 first, second, and third grade students in two rural elementary schools was assessed with CBM methods modified for a literature-based curriculum. Based on the results of this study, standard CBM procedures can be modified to develop local norms for the literature-based classroom. Furthermore, these literature-based CBM norms were found to have adequate test/retest reliability and criterion-related validity. No sampling bias in the selection of individual reading passage probes was found. The extent to which these norms can be used to monitor reading progress must be determined. Further study is necessary before CBM procedures with literature-based reading programs can be used to inform policy and practice. 相似文献

Animals have moral standing; that is, they have properties (including the ability to feel pain) that qualify them for the protections of morality. It follows from this that humans have moral obligations toward animals, and because rights are logically correlative to obligations, animals have rights. 相似文献

A technique of tape construction is described for use in the generation and control of all combinations of auditory-temporal, visual-temporal, and visual-spatial stimulus patterns. This technique allows the development of a set of nine tasks for testing cross-modal and intramodal matching. 相似文献
