In this paper, planning models developed in artificial intelligence are applied to the kind of planning that must be carried out by participants in a conversation. A planning mechanism is defined, and a short fragment of a free-flowing videotaped conversation is described. The bulk of the paper is then devoted to an attempt to understand the conversation in terms of the planning mechanism. This microanalysis suggests ways in which the planning mechanism must be augmented, and reveals several important conversational phenomena that deserve further investigation. 相似文献

ABSTRACT: The relationship of sex, race and region to methods of suicide are used to test the validity of two theories which attempt to explain the choice of methods among suicide victims. The two theories, lethality of intent and differential socialization with firearms, are briefly discussed. Data are collected from official death certificates in five cities during a three year period, 1969 through 1971. The findings provide little support for the lethality of intent theory. Although the differential socialization theory receives partial support, one can argue for a broader sociocultural perspective on methods of suicide which includes location in the social structure as well as regional socialization. 相似文献

Forty‐seven fourth‐and‐fifth grade students whose raw scores on the Gates‐MacGinitie Level D (on‐level test) were determined to be unsuitable were administered an out‐of‐level test (Level C) to ascertain whether the out‐of‐level test would be a more appropriate test for those students. Two questions were addressed in this study. First, are there significant differences in students’ derived scores on the Gates‐MacGinitie when an on‐level test (Level D) that is judged to be unsuitable is compared to an out‐of‐level test (Level C)? Second, is use of an out‐of‐level test more suitable in terms of Roberts’ criterion of the raw scores achieved by the students? There were no significant differences between the derived scores from on‐level and out‐of‐level testing for each of the subtests. The out‐of‐level raw scores did fall within the accepted range for the test to be considered suitable and reliable. 相似文献

This study is a partial replication and extension of a study by Maclay and Sleator (1961) involving judgments of grammaticalness. In an effort to overcome various methodological shortcomings in the earlier study, 152 male subjects were asked to judge a series of 36 word sequences on the dimensions of grammaticalness, meaningfulness, and ordinariness under five different modes of stimulus presentation. Results of the present study failed to confirm the findings reported earlier by Maclay and Sleator. The significance of the results is discussed in relation to several basic issues in the scaling of judgments of grammaticalness. 相似文献
