Referenzsemantik in der Partnermodellierung

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.     

词边界信息在句中的分布

用经过删除的语音歧义句作材料,研究了词边界信息在句中的分布。结果说明,在歧义句中歧义音节是最重要的切分线索;向歧义音节的前后过渡也对词切分有贡献;歧义音节和过渡以外的部分在一定条件下对切分有帮助。     

未来时间的心理结构

２２０名大学生被试用秒、分、小时、日、星期、月和年７个时间单位和模糊统计试验方法对３９个不定的未来时间修饰词作经验赋值,结果表明：①３９个不定的未来时间修饰词与秒、分、小时、日、月、年有一定的对应关系,②未来的心理时间分为三个时间段,即以秒和分为计时单位的“较近的未来”,以小时、日和月为计时单位的“近的未来”,以及以年为计时单位的“远的未来”。③离现在越近的未来时间修饰词,词义模糊度越小,评量的把握度越大;而离现在越远的未来时间修饰词,词义模糊度越大,评量的把握度越小。     

Coping with peer stressors and associated dysphoria: Acculturation differences among Chinese-American children

The purpose of this study was to explore the role of acculturation in coping with stress among 264 Chinese-American children. The results confirmed that the subjects used a variety of coping strategies including diversion, suppression, problem solving, minimization, and retaliation and that certain coping strategies influenced the dysphoria experienced as a result of peer stress. High acculturated children used retaliation significantly more often than their low acculturated counterparts and retaliation was found to be associated with less dysphoria for the high acculturated group. In contrast, low acculturated children who utilized suppression tended to report less dysphoria. Contrary to the hypothesis that general self worth would reduce the relationship between peer stressors and dysphoria, it had no bearing on the association for either acculturated group. The hypothesis that greater perceived social competence would lessen the association between peer stressors and dysphoria also failed to be supported by the data. In fact, for the high acculturation group higher social competence was actually associated with more reported dysphoria. In general, the results suggested that the adaptiveness of particular coping strategies may be influenced by acculturation level and that social competence plays a complicated role in the stress and coping process. Implications for counsellors are discussed.     

时序信息提取机制的探索

对时序信息加工的经典研究是采用新近性判断范型,结果发现其提取机制是以新近性为基础的逆向串行搜索过程。本研究采用新近性判断范型和早远性判断范型对时序信息的提取机制进行了深入的考察,结果表明：（ｌ）提取时序信息既存在逆向串行搜索,又存在顺向串行搜索;（２）早远性判断和新近性判断任务对不同部分时序信息恢复的效应不同,其中早远性判断易化早远部分,新近性判断易化新近部分──表现为对相应部分辨别力的提高和正确反应潜伏期的缩短;（３）在不同的时序信息提取任务中,被试会根据具体条件进行反转反应。     

人际关系适应特征的情境评价方法研究

本研究运用情境评价法对人际关系适应特征进行了实验研究 ,结果表明 :1以 Schutz提出的人际关系六因素为评价标准 ,采用情境评价法比问卷形式能更有效地揭示人际适应特征 ;2在情境评价中 ,以合作为主的情境设置比以竞争为主的情境设置更利于反映出人际适应特征 ;3情境评价采用定向、组织、交流和问题解决等阶段的过程设计符合情境评价的实际进程 ,有助于分阶段展开被试的行为特征 ,提高情境评价的可控性和准确性。     

在自然光照射下工作面照度与照度分布对学前儿童操作技能影响的研究

通过在自然光照射下,测定不同年龄的学前儿童在不同的工作面照度与不同的工作面照度分布情况下,在规定时间内从红色、黄色、绿色３种球状ＰＶＣ塑料颗粒的混合物中分拣出绿色颗粒的多少,来探讨电磁波谱中的可见光部分对学前儿童操作技能的影响。为创造适宜学前儿童进行操作训练的健康环境提供依据。     

侧脑室注射东莨菪碱对条件反射及对海马神经元自发放电的影响

本工作采用食物性运动,条件反射方法和慢性微电极记录技术。条件反射实验在9只兔上进行,海马自发放电的实验在22只兔上进行。在9次实验中,30μg的东莨菪碱注入一侧脑室后,条件反射均受到抑制,而吃食则不受影响。注射剂量为45μg时,注射后3—5分,条件反射完全消失,而吃食行为在了次实验中不受影响,在2次实验中稍有减弱,注射后20分钟左右条件反射开始恢复;侧脑室注射40μg的东莨菪碱后,海马神经元的自发活动无明显改变。文中并对抗胆碱药作用于海马抑制条件反射的可能方式进行了讨论。     

Category width and differentiation in semantic categories

The hypothesis that the judgemental categorizing behaviour measured by Pettigrew's Category-Width scale is linked to semantic categorization is investigated. Individual differences in broad vs. narrow categorizing behaviour measured by the C-W scale are reconceptualized within the framework of Rosch's (1977) theory of human categorization. Two extreme groups on the C-W scale, broad categorizers and narrow categorizers, were selected as subjects. One experiment employed a short-term release-from-proactive-inhibition paradigm. The amount of discrepancy in recall between the preshift and the shift trials was used as an index to perceived semantic distance. The result showed that narrow categorizers perceived the same fuzzy items in a semantic category as less similar to the good exemplars of that category than broad categorizers did. In a further experiment using a semantic-categorization technique, narrow categorizers judged the same fuzzy items as category members less frequently than broad categorizers did, indicating that narrow categorizers possess more differentiated semantic categories than do broad categorizers. These findings are seen as an extension of the differential categorizing behaviour on artificial categories in the C-W scale to semantic categorization for which there is a pre-existing system.
