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.  相似文献

The authors summarise the findings of four recent experiments whichexamined childrens capacity to remember a particular occurrence of arecurring event. Issues discussed include the timing of the interview, thetype of errors, the questioning techniques, the age of the child, theconsistency of the childs account, and the impact of an interveninginterview. Implications for professionals who conduct investigatory orevidentiary interviews with child witnesses are discussed and suggestionsfor future research are also offered.  相似文献

This study compared social values and relationships with parents among American college women of Chinese and European descent. Chinese-American women scored higher on a measure of practicality and pragmatism (mastery), hierarchy, and traditionality. The Euro-American women showed a greater interest in voluntary prosocial behaviour and philanthropy. Both groups of women reported having a sense of self, autonomous of their parents. Within the Chinese-American group, ethnic identification and religion, but not generation, moderated scores on a measure of traditionality of outlook regarding issues of law and order and social equality. We discuss the implications of our findings for recent debates in cross-cultural psychology, including the growing challenge to the individualism-collectivism dimension.  相似文献

This article describes the development and validation of the McMaster Clinical Rating Scale (MCRS). The MCRS is a 7-item scale designed to be completed by a trained rater after completion of an in-depth interview of the family. We present data from four new studies and review previously published articles concerning the reliability, validity, and clinical utility of the MCRS. Adequate interrater reliability and rater stability were obtained. The MCRS was found to correlate significantly with the self-report Family Assessment Device and to discriminate between families in different phases of a depressive disorder.  相似文献

This paper is a contribution to the debate on epistemic foundationalism. Section I expounds and criticises Hans Albert's critical rationalist antifoundationalism position. Section I1 discusses Karl-Otto Apel's ‘transcendental pragmatic’ argument for ultimate epistemic foundations. Section III suggests how the latter argument can be restated so as to avoid ambiguity and yield a plausible case for epistemic foundationalism.  相似文献

Two questions were addressed in the present study: (1) Do autistic and normally developing children exhibit regionally specific differences in electroencephalographic (EEG) activity? (2) Do subgroups of autistic children classified according to Wing and Gould's (1979) system which emphasizes degree of social impairment exhibit distinct patterns of EEG activity? Twenty-eight children with autism (5 to 18 years of age) and two groups of normally developing children (one matched on chronological age and the other on receptive language level) participated. EEG was recorded from left and right frontal, temporal, and parietal regions during an alert baseline condition. Compared to normally developing children, autistic children exhibited reduced EEG power in the frontal and temporal regions, but not in the parietal region. Differences were more prominent in the left than the right hemisphere. Furthermore, subgroups of autistic children based on Wing and Gould's system displayed distinct patterns of brain activity. Compared to autistic children classified as “active-but-odd,” “passive” autistic children displayed reduced alpha EEG power in the frontal region.  相似文献
