The general psychophysical differential equation, dy/dx = W2(y)/W1(x), with the solution y = f(x), where x and y are subjective variables and W1 and W2 their subjective Weber functions, is (a) compared with a corresponding functional equation, and (b) studied from a stochastic point of view by error calculus, Methods for evaluating and handling divergences are proposed and illustrated for a number of combinations of Weber functions. It is shown that either the differential: and the functional equations have the same solution or the difference between the solutions is negligible compared to empirical scatter. The error calculus gives the same result: either no error at all or a negligible one.  相似文献

Four cases of brain-stem tumor were described, in which myokymias were electromyographically derived from the region of several cerebral nerves. An attempt is made to interpret the effects of twitching by reference to the electromyogram. Myokymias are a positive indication of organic brain stem damage. The use subtle techniques of electromyographic examination shows that this muscular hyperkinesis is not so infrequent a symptom as is generally believed.  相似文献

This article deals with relations between mental motor evoking capacity (motority, Putnoky, 1975a, b) and the sensory and affective connotations, as well as certain denotations, of words. Sensory connotation is indexed by degree of visual auditory, and tactual imagery, as assessed on a 7-point scale, while affective connotation is indexed by the usual three factors tapped by the semantic differential. The aspect of denotation used here is the abstractness value of words, also based on rating by scales. The general conclusions about motority are as follows: (1) the finding that its sensory connotations are mainly via theauditory modality of imagery, and especially in correlation with abstract words, suggests that it has a specific function that may have originated in the processing of heard language; (2) it correlates with thepotency andactivity factors of affective connotation, which suggests the existence of a nonspecific function or component in it; (3) correlations with abstractness reflect that motority must have a denotative function or component, especially in case of abstract verbal stimuli. On the basis of the results, motority is supposed to play a regulative role at higher levels of the organization of word meaning in particular.Computation of SD data was carried out under the direction and according to the programming of Professor William H. May in the Center for Comparative Psycholinguistics (Director: Charles E. Osgood), University of Illinois, Urbana-Champaign, with support provided by the National Institute of Mental Health (NIMH 07705) and National Science Foundation (NSF GS 360 and 2012-X).  相似文献

Summary Methods for the measurement of time-errors (TEs) in the comparison of successive stimulus magnitudes are discussed. Combining a Thurstonian scaling method with the assumption of a fixed subjective width of the equal category, independent of stimulus level, a ratio scale for subjective differences within pairs of successive stimuli is derived. In a tone duration comparison experiment, with the TE defined in the terms of these subjective duration differences, data from four experimental groups were compared, the groups using different modes of judging and responding. Only minor effects of this factor were found, and hence it is concluded that the TE is a true perceptual phenomenon rather than an effect of response bias, criterion bias, or mediating verbal responses to the absolute level of stimulation. The quantitative results are interpreted in terms of a general model for the comparison of successive stimuli, employing the concepts of adaptation and differential weighting of sensation magnitudes.This investigation was supported by grants to the author from the University of Stockholm and from the Swedish Office of Administrative Rationalization and Economy (for computer time), and by grants to Mats Björkman and Hannes Eisler from the Swedish Council for Social Science Research, whose free consultation service at the Department of Statistics, University of Stockholm, also benefited the author.  相似文献

By mid-March 2020, most countries had implemented nationwide lockdown policies aimed at decelerating the spread of SARS-CoV-2. At that time, nobody knew how long these policies would have to remain in force and whether they would have to be extended, intensified or made more flexible. The present study aimed to illuminate how the general public in Germany reacted to the prospect of increasing the length, the intensity and/or the flexibility of distancing rules implied by different lockdown scenarios. Endorsement of and compliance with five specific lockdown scenarios were assessed in a large (N = 14,433) German sample. Results showed that lockdown length affected respondents' reactions much more strongly than intensity or flexibility. Additional analyses (i.e., mixture distribution modelling) showed that half of the respondents rejected any further extensions or intensifications, while 20% would endorse long-term strategies if necessary. We argue that policy-makers and political communicators should take the public's endorsement of and compliance with such scenarios into account, as should simulations predicting the effects of different lockdown scenarios.  相似文献
