本文考察了影响行为请求产生的几个因素。使用角色扮演方法，我们从右半球脑损伤(RHD)恢复良好的患者和非脑损伤的对照组参与者那里获得了要求的作品。刺激项目既表现为基于互动中人的特征的人际因素的变化，也表现为基于所带来的要求的情景因素的变化。从每个患者身上获得了一大堆反应。根据请求的直接性、请求本身之外的说明性材料的数量(处理请求语气的一种相对苛刻的方法)和使用“请”(一种相对简单的发出请求信号的装置)对响应进行编码。对患者表现的个案分析揭示了一些常见的异常区域，也揭示了一些特殊的特征。一些患者产生的解释性支持材料比对照组参与者少，他们倾向于不会随着请求情景的变化而改变解释性材料的数量。有趣的是，这些患者中的一些人过度使用“请”，并根据请求场景改变了他们对这个简单设备的使用。所观察到的话语策略很可能是由于语用意识和话语规划方面的缺失。这些结果的一个含义涉及到对风湿性心脏病患者异常话语的恰当描述。在他们的请求中相对缺乏支持性的解释材料可能会导致患者看起来粗鲁或不合适。(C)1999年学术出版社。
This article examines several factors that influence the production of requests for behavior. Using a role-play methodology, we elicited request productions from well-recovered patients with right-hemisphere brain damage (RHD) and from non brain-damaged control participants. The stimulus items represented variation both on interpersonal factors based on characteristics of the people in the interaction and on situational factors based on what was bring requested. A large corpus of responses was elicited from each patient. Responses were coded for request directness, amount of explanatory material over and above the request proper (a relatively demanding method for manipulating the tone of a request), and use of ''please'' (a relatively simple device for signaling a request). Case-by-case analysis of the patients' performances revealed some common areas of abnormality and also some idiosyncratic features. Some patients produced less explanatory supportive material than control participants, and they tended not to vary the amount of explanatory material as a function of the request scenario. Of interest is that some of the same patients overused "please," and varied their use of this simple device as a function of request scenarios. The discourse strategies observed were likely due to deficits both in pragmatic awareness and in planning utterances. One implication of these results concerns an apt description of the abnormal discourse of RHD patients. The relative lack of supportive explanatory material in their requests may result in patients' seeming rude or inappropriate. (C) 1999 Academic Press.
