Whether the perception of vowels takes place in the right or left cerebral hemisphere, or is dependent on bilateral cortical processes, is of importance in our treatment of patients with language deficiencies. To investigate this problem a phonetic test with a series of vowellike stimuli was administered to 68 right-handed adult patients with cerebral lesions, mainly of vascular origin. The results were compared to the results in a control group of 19 speech therapists. Second, a neuroradiologic method was developed in order to visualize the anatomic site of Wernicke's area in the left hemisphere on CT scans. This method formed the basis for an evaluation of the extent and localization of the patients' lesions in Wernicke's area. Of 46 patients with lesions in the left hemisphere, 19 had no perceptual disturbances and 27 had severe perceptual disturbances with lesions predominantly located in Wernicke's area. Twenty-two patients with lesions in the corresponding area in the right hemisphere showed no perceptual disturbances. The results of this investigation appear to indicate that the perception of vowels in right-handed persons is unilaterally located in Wernicke's area in the left hemisphere. 相似文献

Search for odd-one-out feature targets takes longer when the target can be present in one of several dimensions as opposed to only one dimension (Müller, Heller, & Ziegler, 1995; Treisman, 1988). Müller et al. attributed this cost to the need to discern the target dimension. They proposed adimension-weighting account, in which master map units compute, in parallel, the weighted sum of dimension-specific saliency signals. If the target dimension is known in advance, signals from that dimension are amplified. But if the target dimension is unknown, it is determined in a process that shifts weight from the nontarget to the target dimension. The weight pattern thus generated persists across trials, producing intertrial facilitation for a target (trialn+1) dimensionally identical to the preceding target (trialn). In the present study, we employed a set of new tasks in order to reexamine and extend this account. Targets were defined along two possible dimensions (color or orientation) and could take on one of two feature values (e.g., red or blue). Experiments 1 and 2 required absent/present and color/orientation discrimination of a single target, respectively. They showed that (1) both tasks involveweight shifting, though (explicitly) discerning the dimension of a target requires some process additional to simply detecting its presence; and (2) the intertrial facilitation is indeed (largely) dimension specific rather than feature specific in nature. In Experiment 3, the task was to count the number of targets in a display (either three or four), which could be either dimensionally the same (all color or all orientation) or mixed (some color and some orientation). As predicted by the dimension-weighting account, enumerating four targets all defined within the same dimension was faster than counting three such targets or mixed targets defined in two dimensions. 相似文献

Intractable controversies and other types of policy disagreements correspond to policy problems with a different structure.
The more structured a problem is, the more consensus there is about which values and information are at stake in the process
of problem solving. Policymakers like to treat problems in as structured a way as possible. Three policy strategies are described
to move away from the unstructured to the more structured problem type. However, policymakers run the risk of oversimplifying
an ill-structured problem, which means that elements of the problem situation relevant to other actors are overlooked or denied.
Hence, policy controversies may become intractable. The remedy is a fourth strategy, characterised by problem structuring.
This strategy requires political participation of actors with different views on the problem, and an argued political problem
choice.
His main research areas are problem structuring in public policy, knowledge use, environmental risk, technology and democracy.
He is currently working on knowledge-based policy strategies for addressing the issue of climate change.
His research interest is to develop and apply discursive and/or argumentative approaches to the policy process. 相似文献

To test the hypothesis that the major evaluative beliefs postulated by Rational-Emotive Behaviour Therapy are related to marital adjustment, 50 married couples completed the Dyadic Adjustment Scale (DAS) and the Survey of Personal Beliefs (SPB). Significant correlations were found between DAS scores and three subscales (Other directed shoulds, Low frustration tolerance and Self worth) of the SPB. On the interpersonal dimension of assumed similarity, females in the high dyadic adjustment group were better able to predict their spouses' awfulizing, low frustration tolerance and self-worth beliefs than were females in the low adjustment group. However, the present study offers only limited support for the hypothesis that interpersonal perception of irrational evaluative beliefs is related to marital adjustment. 相似文献

Canalized F-waves and H-reflexes occurring on small hand and foot muscles are to be considered symptoms of central disinhibition. Occurrence of these waves and reflexes in patients with hemispastic syndrome is analyzed and correlated with clinical aspects. 相似文献

A laboratory study was conducted to examine the role of explorative decision making for interpersonal conflict resolution. Participants were 64 male students, who had to negotiate for an outcome distribution against bogus enactment of two confederates. Questionnaire and observational data, which were taken before, during and after the negotiation revealed strong support for hypothesized effects of coping with situational antagonism. Results indicate that substantial shifts take place according to locus of decision control and that behavior is determined by different decision preferences as conflict resolution proceeds. 相似文献

Side-effects and complications of lithium therapy were examined by evaluation of data registered from 73 patients. Transitory subjective complaints would often occur during the initial phase of therapy, but they do not require any additional therapy. Occasional development of struma and sometimes high increase of body weight require regular controls of these values. Disposing factors concerning the possible occurrence of epileptic seizures and extra-pyramidal disorders under lithium therapy are Melipramin as well as organic cerebral lesions. 相似文献

A combination of several psychotherapeutic methods will be meaningfull only if they are tuned to, and supplement, each other. Indiscriminate combinations may produce harmful effects. The choice of psychotherapeutic methods depends upon the objective that the psychotherapist desires to accomplish. In psychotherapy it is essential that all actions taken be governed by plans worked out in accordance with the particular objectives to be accomplished. 相似文献

The authors, after presenting a survey of the literature on the treatment of multiple sclerosis with immunosuppressants, report their experience with Imurek. Of 53 patients with a chronic and progressive course of the disease, objective improvement could be observed in 17. In 20 patients the symptomatology remained unchanged, although 4 of them reported subjective improvement. In 16 patients, progression of the disease could not be stopped. Better results of treatment could be obtained for those forms of the disease where the course was, first, in the form of what may be referred to as outbursts and, later, in a chronic and progressive form. -Possible side effects are pointed out. 相似文献

Zusammenfassung Mit Hilfe eines 2×2×2-Designs wurde die Wirkung der Anzahl der Signalflächen, Anzahl der irrelevanten Reize und Art der Motivation auf die Vigilanzleistung untersucht. Dabei zeigte sich, daß die Wahrscheinlichkeiten von verpaßten Signalen und falschen Alarmen mit der Anzahl der Signalquellen zunehmen. Die Menge der Nicht-Signale gleicher Modalität wie die Signalreize beeinflußt weder die Signalentdeckungen noch die falschen Alarme.Weiterhin wurde versucht, eine Systematisierung von Motivationswirkungen in Vigilanzaufgaben im Rahmen des detection-Modells vorzunehmen. Bei großen Gewinnen für richtige Signalentdeckungen und geringen Verlusten für falsche Alarme (Risiko-Motivation) ergab sich eine wesentlich höhere Entdeckungswahrscheinlichkeit und eine geringfügig höhere Rate von falschen Alarmen als bei geringen Gewinnen für richtige Signalentdeckungen und hohen Kosten für falsche Alarme (Vorsichts-Motivation). Weiterhin zeigte sich unter Risiko-Motivation ein Abfall der Entdeckungswahrscheinlichkeit und bei Vorsichts-Motivation ein Anstieg, während sich die entsprechenden Raten der falschen Alarme im Verlauf der Aufgabe nicht signifikant veränderten.

Experimental application of detection theory to vigilance behaviour
Summary In a 2×2×2-design the effects of number of dials, number of irrelevant stimuli and kind of motivation were combined. It was found out, that probabilities of missed signals and false alarms increased with spatial uncertainty. The number of irrelevant stimuli, which were of equal sensory modality as the relevant stimuli, had no influence either on detection probability or on false alarms rate.Further attempt was made to systematize effects of motivation on vigilance performance in the detection model. With great values for hits and small costs for false alarms (risky motivation) there was an essentially higher detection pobability and a slightly higher false alarms rate than with small values for hits and high costs for false detections (cautious motivation). The probabilities of detections decreased under risky motivation and increased under cautious motivation as the watch prolonged, whereas the corresponding probabilities of false alarms showed no significant changes.
