Mild to moderate Parkinson's disease shows more denervation in the posterodorsal striatum and sparing of the anteroventral striatum. Dopaminergic medications can interfere with anteroventral striatum function by overdosing this relatively intact structure. The authors determined how regional striatal denervation affects medication-associated sequence learning impairment in Parkinson's disease. Eighteen Parkinson's patients performed motor sequence learning on and off levodopa. Patients underwent 11C-dihydrotetrabenazine positron emission tomography scans to measure nigrostriatal denervation. Patients with more preserved putamen were more likely to exhibit levodopa-associated sequence learning impairments. Furthermore, the ratio of denervation in the anterior to posterior dorsal putamen predicted the level of learning differences on and off levodopa. These results demonstrate that the spatial pattern of nigrostriatal dopaminergic denervation predicts medication responsiveness for motor sequence learning. 相似文献

A total of 182 undergraduate students from China and the United States participated in a study examining the presence of stereotypical perceptions regarding creativity and deductive reasoning abilities, as well as the influence of stereotype on participants' performance on deductive reasoning and creativity in nonverbal form. The results showed that participants from both China and the United States believed that Americans have better creativity abilities than Chinese and that Chinese have better deductive reasoning skills than Americans. Significant cultural difference in the performances on the measures of creativity was found. The cultural difference in deductive reasoning was found between Chinese participants in China and the Caucasian (not the Asian) participants in the United States, which were somewhat congruent to the stereotypical perceptions. However, the study did not find that stereotypic perceptions directly influenced participants' performance on deductive reasoning and creativity. 相似文献

We have integrated the basic psychological needs approach from self‐determination theory with motive disposition theory in order to enhance the prediction of flow experience in sports. We hypothesize that an environment that enables people to fulfill their basic psychological needs for competence and social relatedness results in flow. Additionally, we assume that the effect of competence need satisfaction is moderated by the achievement motive and that the effect of need‐for‐relatedness satisfaction is moderated by the affiliation motive. Four studies show the expected positive effects of need satisfaction on flow and further confirm that high achievement and affiliation‐motivated individuals benefit more from competence and relatedness sports environments, respectively, than individuals low in these motives. 相似文献

Research shows that we spontaneously imitate people. Moreover, empathy predicts the degree of this non‐conscious imitation. Little is known, however, if or how this expression of empathy is influenced by stable physical characteristics of our interaction‐partners. In two studies, we tested whether attractiveness of others moderated the relation between empathy and imitation. While seeing a woman performing joystick movements, participants either imitated, or non‐imitated these movements. Results showed that the higher participants empathy score, the faster they imitated an attractive person. The level of empathy did not predict the degree of imitation of unattractive targets. The findings demonstrate that the expression of empathy through imitation can be moderated by attractiveness, thereby introducing a new dimension to the conditionality of empathy. 相似文献

Children of refugee families who have survived torture often have emotional, psychosomatic and behavioural problems as well as problems with learning. In order to understand the difficulties of these children, we have to recognize the complicated interaction of cumulative traumatic strain and recurring exposure to shocking violence. The traumatic experiences of the child in the country of origin take place in the broader context of chronic danger and persecution, often to be followed in the country of exile both by recurrent family strain and social estrangement. In the transference this complicated mixture of repeated trauma and chronic strain may show as a pervasive tendency to retreat to defensive survival strategies combined with continual repetition of more specific traces of the impact of the trauma on the individual. This paper focuses on how the enacted survival strategies can be contained and understood in the transference. In due course the compulsive repetition can be given meaning as a precondition for better integration through symbolic thought and self-understanding. 相似文献

This paper examines al-Fārābī's logical thought within its Arabico-Islamic historical background and attempts to conceptualize what this background contributes to his logic. After a brief exposition of al-Fārābī's main problems and goals, I shall attempt to reformulate the formal structure of Arabic linguistics (AL) in terms of the ontological and formal characteristics that Arabic logic is built upon. Having discussed the competence of al-Fārābī in the history of AL, I will further propose three interrelated theses about al-Fārābī's logic, in terms of which I will attempt to redefine it: the logico-linguistic conception, the project of logicization, and nuclear logic. The final question that will arise is how Aristotle's logic could be built upon AL, which has a nature contrary to logic. The present paper also contributes to examining our traditional research habits in Arabic studies. 相似文献

In the last two decades, there has been increasing interest in a re-evaluation of Frege's stance towards consistency- and independence proofs. Papers by several authors deal with Frege's views on these topics. In this note, I want to discuss one particular problem, which seems to be a main reason for Frege's reluctant attitude towards his own proposed method of proving the independence of axioms, namely his view that thoughts, that is, intensional entities are the objects of metatheoretical investigations. This stands in contrast to more straightforward interpretations, which claim that Frege's hesitancy is mainly due to worries concerning the logical constants or what counts as a logical inference. 相似文献

Self-Determination Theory (Deci and Ryan in Intrinsic motivation and self-determination in human behavior. Plenum Press, New York, 1985) suggests that certain experiences, such as competence, are equally beneficial to everyone’s well-being (universal hypothesis), whereas Motive Disposition Theory (McClelland in Human motivation. Scott, Foresman, Glenview, IL, 1985) predicts that some people, such as those with a high achievement motive, should benefit particularly from such experiences (matching hypothesis). Existing research on motives as moderators of the relationship between basic need satisfaction and positive outcomes supports both these seemingly inconsistent views. Focusing on the achievement motive, we sought to resolve this inconsistency by considering the specificity of the outcome variables. When predicting domain-specific well-being and flow, the achievement motive should interact with felt competence. However, when it comes to predicting general well-being and flow, felt competence should unfold its effects without being moderated by the achievement motive. Two studies confirmed these assumptions indicating that the universal and matching hypotheses are complementary rather than mutually exclusive. 相似文献

The current study tested gender differences in the developmental transition from drawing cubes in two‐ versus three dimensions (3D), and investigated the underlying spatial abilities. Six‐ to nine‐year‐old children (N = 97) drew two occluding model cubes and solved several other spatial tasks. Girls more often unfolded the various sides of the cubes into a layout, also called diagrammatic cube drawing (object design detail). In girls, the best predictor for drawing the cubes was Mental Rotation Test (MRT) accuracy. In contrast, boys were more likely to preserve the optical appearance of the cube array. Their drawing in 3D was best predicted by MRT reaction time and the Embedded Figures Test (EFT). This confirmed boys' stronger focus on the contours of an object silhouette (object shape). It is discussed whether the two gender‐specific approaches to drawing in three dimensions reflect two sides of the appearance–reality distinction in drawing, that is graphic syntax of object design features versus visual perception of projective space. 相似文献
