This paper is a case study of an aphasic patient who displays two interesting characteristics, namely, (1) a dissociation between his oral and written disorders (i.e., oral Wernicke vs. written Broca); (2) an agraphia-alexia syndrome in which the picturability of the entities referred to by words plays an important role. Some of the characteristics shown by this patient have been well described concerning reading but never concerning writing. This second aspect is particularly emphasized. 相似文献

The paper discusses the mathematical foundations of a technique of multidimensional scaling, generalizing Guttman scaling, in which the structure of the embedding space relies only on ordinal concepts. An empirical relation is represented as an intersection of a minimal number (called bidimension) of Guttman relations. Fairly complete results are given for the cases of bidimensions 1 and 2. In the general case, the main results are based on the equivalence between the bidimension and the dimension of a certain partial order. A characterization of the bidimension as the chromatic number of some hypergraph is also provided. 相似文献

French children between 4 and 10 years old were asked to draw representations of French negative sentences. The results indicated that in most cases only the verb is negated when the noun phrase to the right of the negation is introduced by a definite article, but when the noun phrase is introduced by an indefinite article, it is most often the noun phrase itself that is negated. This effect is clear even in 4-year-olds, and it serves to demonstrate that the interpretation of negative sentences depends on phenomena of surface structure as well as of deep structure. 相似文献

We observed 32 subjects whose biological parents were both unskilled workers. Abandoned at birth, the subjects had been placed at approximately 4 months of age into families spanning the top 13% of the socio-professional scale. The effects of this change in social class were estimated by comparisons with groups of children of unskilled workers observed in two large scale studies. An internal control group was also available for 20 of the 32 subjects: the biological half-siblings who had been reared in their ‘natural’ environment. The effects observed are an increase of 14 IQ points in the mean IQ score estimated with 2 tests and a reduction by a factor of 4 in the probability of repeating a grade. These are significant despite the small number of subjects; we have shown that the bulk of these effects cannot be attributed to methodological biases. Our observations thus provide a direct quantitative answer to the question posed by Jensen in 1969. 相似文献

In order to investigate the nature of the processes that promote the observational learning of conservation, nonconservers were allowed or not visual access to the conservation stimuli while an adult model verbalized the conservation rule. In addition, after each demonstration the subjects were submitted to one of four conditions. The first three conditions involved a short pause during which the observers respectively kept seeing the stimuli, had to visualize them mentally, and had to visualize mentally some irrelevant stimuli; no interruption occurred in the fourth condition. As predicted, the withdrawal of visual information at the time of rule exemplification was accompanied with lower learning scores. However, equivalent acquisition was found with respect to each of the conditions in which the subjects were invited to examine specific stimuli after rule modeling. Altogether these data were discussed in terms of the greater and lesser extent to which the conditions permitted the children, during the observational training, to practice covertly the modeled solution. 相似文献

IntroductionConfidentiality is crucial to the establishment of a strong patient-physician relationship. However, certain situations create a dilemma for the physician who is faced with the choice of either respecting medical confidentiality or protecting others from a serious risk of violence.ObjectiveThis study aimed to observe how lay people and health professionals assessed the acceptability of breaching confidentiality when a physician is confronted to a patient showing signs of terrorist radicalization.MethodA total of 228 participants (174 from the general population and 54 health professionals) judged the acceptability of 54 scenarios which were constructed through the orthogonal combination of 4 factors frequently mentioned in the literature: presence of a “Psychiatric disorder”; “Signs of radicalization”; “Projects of violence”; “Collegiality”. Variance and cluster analyses were performed on all the raw data.ResultsResults showed that all factors influenced the judgment of participants but that “Psychiatric disorders” had a weaker impact. Five clusters were identified: “Favorable if collegiality” (n = 23); “Favorable to breach confidentiality” (n = 77); “Unfavorable to breach confidentiality” (n = 26); “Sensitive to all factors” (n = 71); “Favorable if violence” (n = 31), respectively with mean ratings of 5.87, 8.42, 3.64, 6.30 and 7.16, on an acceptability scale of 0–10.ConclusionThe importance that the great majority of participants attribute to these factors indicates that they influence their judgments in this specific context. 相似文献
