Based on the results of an event-related brain potentials (ERP) experiment (van Berkum, Brown, & Hagoort. 1999a, b), we have recently argued that discourse-level referential context can be taken into account extremely rapidly by the parser. Moreover, our ERP results indicated that local grammatical gender information, although available within a few hundred milliseconds from word onset, is not always used quickly enough to prevent the parser from considering a discourse-supported, but agreement-violating, syntactic analysis. In a comment on our work, Brysbaert and Mitchell (2000) have raised concerns about the methodology of our ERP experiment and have challenged our interpretation of the results. In this reply, we argue that these concerns are unwarranted and, that, in contrast to our own interpretation, the alternative explanations provided by Brysbaert and Mitchell do not account for the full pattern of ERP results. 相似文献

Zusammenfassung. Dieser Artikel beschreibt einen Ansatz zur Codierung und Analyse pädagogischer Interaktionen zwischen Lernenden und Experten im Bereich der Luftfahrt-Technik im Rahmen einer intelligenten tutoriellen Lernumgebung zur Fehlererkennung und -behebung (Sherlock 2). Es werden zwei prototypische maschinelle Lernverfahren dargestellt, welche bei der Analyse eines Corpus von Dialogprotokollen eingesetzt werden. Die Verfahren generieren der Diskursstruktur möglichst gut entsprechende Grammatiken. Die gefundenen Grammatiken führten zu neuen Einsichten hinsichtlich der Funktion bestimmter Sprechakte in tutoriellen Dialogen sowie zu klaren und präzisen Modellen von Erklärungsdialogen bei Diagnoseproblemen. Summary. This paper describes our approach to coding pedagogical interactions that took place between avionics students and domain experts in an ITS for electronic troubleshooting called Sherlock 2. We also describe prototype machine learning systems that we developed to learn grammars of discourse structure. The grammars revealed instructional functions of particular speech acts that we had not been aware of, and provided concise models of explanations common in diagnostic tasks. 相似文献

Being imprisoned appears to lead some individuals to commit suicide whereas others appear to suffer little stress. Previous
research has identified three groups of male prisoners (young remand, young sentenced and those serving life sentences) where
the incidence of suicide is high. The present study examined institutional and individual factors that were related to levels
of anxiety, depression and psychological well-being within these groups. A psychiatric history, religious faith, feelings
of guilt, lack of close friends outside prison, or disinclination to take part in sport, training or hobbies were found to
be associated with high levels of anxiety, depression and psychological morbidity. So too were the severity of environmental
hassles and worries. The implications of these findings are discussed. 相似文献

A study is presented on the effects of discourse–semantic and lexical–syntactic information during spoken sentence processing. Event-related brain potentials (ERPs) were registered while subjects listened to discourses that ended in a sentence with a temporary syntactic ambiguity. The prior discourse–semantic information biased toward one analysis of the temporary ambiguity, whereas the lexical-syntactic information allowed only for the alternative analysis. The ERP results show that discourse–semantic information can momentarily take precedence over syntactic information, even if this violates grammatical gender agreement rules. 相似文献

Little is known about the relationship between the variability of moods and the tendency to experience depressed mood. The
moods of twenty-five student subjects were measured over a period of some 30 days using scales assessing positive affect and
negative affect. An index of mood variability was computed. This was correlated with two measures of average level of depression.
The results showed a strong correlation between variability of moods and level of depression. High levels of mood variability
accompanied high levels of depressive state in this nonclinical sample. 相似文献
