Williams Syndrome (WS) is a disorder caused by a delection in chromosome 7, with a cognitive profile characterised by mild to moderate mental deficiency and difficulties in visual-spatial processing, which contrasts with a relative preservation of linguistic functions and narrative production. In this study, verbal performance was analysed in two groups of participants (N = 3), Portuguese and Spanish, genetically diagnosed with WS. Scores were low in Verbal IQ, as in Performance IQ. Narrative performance showed low coherence with respect to structure, process, and content. WS verbal performance was affected and there was no difference between both groups. We could not find any dissociation between cognitive functioning and linguistic production. 相似文献

We tested the hypothesis that our ability to detect fine kinematics variations is tuned to reveal more subtle differences when the motion pattern belongs to the observer compared to another individual. To this purpose, we analyzed the responses of 15 subjects in a same-different task on pairs of movements, which could belong to one or two different subjects. Self vs. Other comparisons were obtained by presenting both the observer's and another participant's kinematics. Subjects responded faster and more accurately when they observed their own gestures compared to movements of another participant. In the latter case, slight kinematic differences were more likely to remain undetected. These findings are discussed within an ecological framework: in observing others, we are more concerned with detection of goals and intentions, i.e., outstanding variations in motion patterns. Conversely, in self-observation detection of more subtle differences is required to facilitate learning and optimization of motor acts. 相似文献

In order to study neuropsychological characteristics of subcortical-frontal brain regions function and assessment of their relation with vulnerability to schizophrenia 59 patients and 23 controls were investigated using Luria's neuropsychological methods. The analysis established bilateral abnormalities of the function of prefrontal and profound frontal lobe zones in patients as compared with controls. These abnormalities were more predominate in the left hemisphere. Point biserial correlation coefficients of determined integrative neuropsychological indicators with liability to schizophrenia were 0.39 +/- 0.11 and 0.28 +/- 0.09, for the left and right brain zones respectively. The obtained data permits discussion of the integrative neuropsychological indicators of subcortical-frontal brain regions as potential markers of liability to schizophrenia and confirms the role of structural and functional brain asymmetry in the pathogenesis of schizophrenia. 相似文献

The authors summarized EEG findings and defined the nature of the intercentral EEG relationships in different functional states in healthy subjects and patients with organic cerebral pathology, based on a coherence analysis. Similar EEG characteristics in healthy individuals were identified: an anterior-posterior gradient of average coherence levels, the type of cortical-subcortical relationships in anterior cerebral structures. Right- and left-handed individuals showed frequent and regional differences in EEG coherence, which mainly reflected specificity of intracortical relationships. Development and regression of pathology in right-and left-handed individuals with organic brain lesions were thought to be caused by these differences. Lesions of regulatory structures (diencephalic, brain stem and limbic structures) provoked a more diffused kind of changes of intercentral relationships, in contrast to cortical pathology. These changes tended to reciprocate. The dynamic nature of intercentral relationships and their interhemispheric differences was revealed when changing functional states of the brain (increase and decrease of functional level) in healthy individuals and patients with organic cerebral pathology in the process of conscious and psychic activity restoration. Changing activity predominance of certain regulatory structures was considered one of the most important factors determining the dynamic nature of EEG coherence. 相似文献

Differences in professional choice and experience may explain age differences in working memory performance of elderly people. The aim of this study was to examine whether expertise and prolonged practice in verbal and visuo‐spatial abilities reduce age differences in laboratory working memory tasks. The effects of age and expertise on working memory performance were examined in three age groups in two different experiments. Firstly, the role of visuo‐spatial expertise was analysed by examining age differences in architects. Secondly, people with extensive experience in verbal abilities (literary people) were tested in order to evaluate the effect of professional verbal experience. Architects and literary people outperformed a group of unselected age peers on tasks related to professional expertise only, but not on general working memory tests. There was no interaction between age and experience, suggesting that professional experience does not increase differences between experts and non experts and cannot modulate age‐related effects.

The article demonstrates that post-Soviet academic debates about theoretical concepts and visions of truth can be usefully
interpreted in terms of different “class positions” of knowledge producers. One academic faction is interested in academic
freedom, autonomy, and corporate solidarity, as the social and cultural capitals of its members are involved with the global
symbolic market. The capitals of the other group are invested into the slightly modified Soviet academic system and local
symbolic fields. Intellectuals necessarily are aligned with more powerful social actors and thus become involved in divisions
and struggles that they cannot escape. 相似文献

Previous studies have shown that bilingual adults use more gestures than English monolinguals. Because no study has compared
the gestures of bilinguals and monolinguals in both languages, the high gesture rate could be due to transfer from a high
gesture language or could result from the use of gesture to aid in linguistic access. In this study we tried to distinguish
between those causes by comparing the gesture rate of 10 French–English bilingual preschoolers with both 10 French and 10
English monolinguals. All were between 4 and 6 years of age. The children were asked to watch a cartoon and tell the story
back. The results showed the bilingual children gestured more than either group of monolinguals and at the same rate in both
French and English. These results suggest that that the bilinguals were not gesturing because they were transferring the high
gesture rate from one language to another. We argue that bilinguals might gesture more than monolinguals to help formulate
their spoken message. 相似文献

We explored bias and its perception in newspaper reports of the 2002 Olympics figure skating controversy. American and Russian articles were examined for their perceptions of the Canadian and Russian pairs' performances, directionality of the Russian and American media and publics' biases, and media awareness of those biases. Reporters' accounts varied as a function of country of affiliation and indicated a one‐sided acknowledgment of media and public bias. The American media acknowledged a pro‐Canadian bias in their reporting; there was no self‐bias acknowledgment in the Russian press. Country of affiliation produced one‐sided coverage of this event, and even the American media's awareness of self‐biases did not ensure bias‐free reporting. These findings are discussed amid respective countries' cultural and political contexts. 相似文献

Spontaneous preferences towards possible prey have been little investigated using targets in motion. Preferences of domestic
chicks (Gallus gallus) to peck at video-images of stimuli representing live insects moving along their longer body axis (i.e. “forwards”) or along
the shorter body axis (i.e. “sideways”) were investigated. Chicks presented with both types of stimulus displayed a significant
preference for pecking at stimuli moving sideways. This preference was already present on day 1 post-hatching, and it strengthened
on day 6 for those chicks that had experienced pecking at live insects. Head angles used to fixate the stimuli prior to pecking
were also analysed and were consistent (i.e. 30°–35° and 60°–65°) with those reported for fixation of non-edible targets (larger
stimuli at a distance). In a first control experiment the same video-presented stimuli were used but the insect’s legs were
removed to reduce flickering. In a second control experiment, paper-printed images of the whole insect were used. In both
cases, the sideways direction of movement was clearly preferred. Overall, our data show that chicks have a spontaneous preference
to peck at video-images resembling live insects moving along their shorter body axis. Sideways movement may constitute a crucial
signal attracting chicks’ attention and enhancing predatory responses possibly because of stronger stimulation of motion detectors. 相似文献
