This study aims to determine whether specific neuropsychological performance impairments in borderline patients can be objectified and whether these findings indicate frontal dysfunctions. Twenty-three patients with borderline personality disorder and 23 normal controls were examined using a neuropsychological test battery to assess intelligence, attentiveness, proneness to interference, learning and memory, as well as planning and problem solving. All subjects filled out standardized questionnaires to assess aggressiveness and impulsiveness in the context of these cognitive performance areas. The neuropsychological test results of the borderline patients were comparable to those of the controls. Although there were no indications of frontal dysfunction of cognitive information processing, inverse correlations were found between the severity of borderline-related personality traits regarding impulsiveness and various areas of cognitive performance. Borderline personality patients show no indications of frontal cognitive dysfunction. Further research is needed to clarify the relationship between impulsiveness and cognitive information processing in borderline personality disorder, including a dimensional approach to personality and personality disorder. 相似文献

The contribution of EEG coherence to the investigation of language 总被引:10,自引:0,他引:10
The contribution of EEG coherence analysis to the investigation of cognition and, in particular, language processing is demonstrated with examples of recent EEG studies. The concept of EEG coherence analysis is explained, and its importance emphasized in the light of recent neurobiological findings on frequency-dependent synchrony as a code of information processing between nerve cell assemblies. Furthermore, EEG coherence studies on naturally spoken and written word and sentence processing are reviewed and experimental results are presented giving new insights into the occurrence of "transient functional language centers" within the brain. 相似文献

A study is reported of gender differences in a haptic version of three Piagetian tests that assess understanding of Euclidian space. A raised-line drawing kit was used both for subject responses and for production of stimuli. To test understanding of the horizontal, subjects felt pictures of a jar at four tilts and were asked to draw the water line. Two methods were used to examine understanding of the vertical. First, subjects drew a hanging electrical cord and light bulb, attached to the ceiling of a bus, parked on hills of four different angles. Subsequently, subjects drew telephone poles (represented by a single line) on hills of four different angles. In the jar task, males and females showed comparable performance, both groups showing large errors. Judgments of the vertical were very similar for males and females in the bus task, but errors diminished considerably for both genders when subjects drew telephone poles on hills. It is suggested that better judgments of the vertical in the pole task probably derive from the use of body-centered spatial reference information. 相似文献

A general theory of the relationship of binocular visual space to physical space is formulated within a conjoint measurement framework. Psychophysically motivated invariance relations induce various functional equations. Another class of functional equations arises if we additionally assume the validity of a different psychophysical theory that is based on a formula suggested by A. A. Blank. We solve and interpret most of these equations and point out an unsolved problem. The obtained results lead to a measurement-theoretic foundation of the psychophysical assumptions underlying the Luneburg theory of binocular vision. They also contribute to clarifying the relationship between the presented general theory and Blank's approach. Copyright 1999 Academic Press. 相似文献

The following study investigated the effect of writing systems (logographic vs. alphabetic) on the temporal organization of reading aloud. More specifically, we wished to test Perfetti and Zhang's (1995) assertion that the reader of an alphabetic system can do better at recovering the phonological form, less well at recovering the semantic category of the word (p. 186f.). Native speakers of Chinese and German read a semantically identical passage from texts written in their own language. The Chinese version consisted of 132 characters (132 syllables), the German of 80 words (also 132 syllables). In accord with Perfetti and Zhang's position, Chinese readers articulated significantly more slowly; they also used significantly more pauses. Moreover, German readers used a set pattern of pause positions, whereas Chinese did not. Logographic and alphabetic determinants of reading aloud are discussed. 相似文献

Experimental research conducted with student participants has documented that feeling powerful or powerless (psychological power) affects outcomes with high practical relevance for organizations. However, it is unclear how results from these studies can be generalized to organizational settings in which individuals have various roles that imply more or less objective power. To address this gap, we present a theoretical framework to aid in the understanding of how objective power in organizations affects psychological power. We assume that stable differences in organizational rank (i.e., structural power) determine the likelihood of interactions with superiors, subordinates, or peers. These interactions give rise to within-person variation in situational power which should lead to dynamic fluctuations of psychological power and eventually its outcomes. Results of a preregistered experiment (n = 190 participants) and a preregistered experience sampling study (n = 129 participants) conducted with working adults support our key predictions: Structural power was associated with the likelihood of being in a high power versus low power situation. Within-person differences in situational power were related to feelings of power such as judgments about (1) one's own ability to influence others in a given social situation (i.e., interpersonal power) and (2) one's own competence, agency, autonomy, and independence (i.e., personal power). 相似文献
