Among numerous procedures for determination of the psychophysical relation, one approach has seldom been applied. Essential in this method is to present a set of stimuli whose intensity increases in fixed time following different forms. The objective stimulus increment, which the subjects perceive as linear growth directly, represents the inverse psychophysical relation. In this paper the method was tested in the fields of click frequency and sound pressure. This procedure was named "Perception of the Form of Stimulus Increment in Time". In comparison to other psychophysical approaches, this one has several advantages. The principal ones are the following: (1) In assessing the psychophysical relation it is not necessary to try to measure the perceptual magnitude; and (2) the psychophysical relation is directly determined by its dynamic pattern. In this paper modifications to the method are reported which facilitate the subject's task and avoid some differences in subjects' individual approaches to the task. The modified procedure leads to results satisfactory independent of the influence of the factors irrelevant to the psychophysical relationship. 相似文献

Summary The present paper evaluates the two standard approaches to the processing of inflected morphology (decomposition and the satellite-entries hypothesis) in the scope of the results obtained on Serbo-Croatian inflected noun forms. It was demonstrated that the decomposition hypothesis cannot account for most of the results. On the other hand, some of the critical experiments upon which the satellite-entries hypothesis was based failed to replicate, and the hypothesis was rejected on empirical grounds. The approach proposed in the present study assumes that processing effects observed with inflected Serbo-Croatian noun forms are based on the subject's sensitivity to the amount of information (i. e., bits) within a particular inflected form. It was demonstrated that the basic unit of the subject's sensitivity is the amount of information derived from the average frequency per syntactic function within a particular inflected form of a noun. This parameter accounts for all the observed processing variability of the inflected Serbo-Croatian noun forms. 相似文献

The logic of the weak law of excluded middleKC

In Experiments 1 and 2, we investigated long-term repetition priming effects in Serbian under crossalphabet and cross-modal
conditions. In both experiments, results followed the same pattern: significant priming in all conditions and no significant
reduction in priming in the cross-modal as opposed to the cross-alphabet condition. These results are different from those
obtained in English (Experiment 3), in which a modality shift led to a reduction in priming. The findings are discussed within
a theoretical framework, in which long-term priming is a by-product of learning within the language system. A full list of
word stimuli for all three experiments presented in this article can be found at www.psychonomic.org/archive. 相似文献

Anchoring theory (Gilchrist et al, 1999 Psychological Review 106 795-834) predicts a wide range of lightness errors, including failures of constancy in multi-illumination scenes and a long list of well-known lightness illusions seen under homogeneous illumination. Lightness values are computed both locally and globally and then averaged together. Local values are computed within a given region of homogeneous illumination. Thus, for an object that extends through two different illumination levels, anchoring theory produces two values, one for the patch in brighter illumination and one for the patch in dimmer illumination. Observers can give matches for these patches separately, but they can also give a single match for the whole object. Anchoring theory in its current form is unable to predict these object matches. We report eight experiments in which we studied the relationship between patch matches and object matches. The results show that the object match represents a compromise between the match for the patch in the field of highest illumination and the patch in the largest field of illumination. These two principles are parallel to the rules found for anchoring lightness: highest luminance rule and area rule. 相似文献

Disturbed sleep may be associated with a multitude of environmental, medical, and psychological conditions. Since sleep disturbances are leading manifestations of major depression, a common potentially fatal disorder, persons with disturbed sleep must be screened for depression. Different forms of disturbed sleep are associated with specific subtypes of depression. Those with evidence of depression must then be referred for prompt treatment to abort serious adverse outcomes, including suicide. 相似文献

Croatian elementary school children in grades 4 to 6 (N= 151) reported on direct and indirect aggressive behaviors of their classmates. Acceptance and rejection by classmates were also assessed, employing the sociometric nomination technique. Correlational analyses revealed that both forms of aggression were related to peer rejection, but unrelated to peer acceptance. Girls' aggression was more strongly related to peer rejection than boys' aggression, independent of the type of aggression. Aggressive children of both genders tended to be more rejected by their same-gender classmates than by classmates of the opposite gender. Results were discussed in terms of children's attitudes towards aggression, and gender stereotyped perception of appropriateness of aggressive behavior. A need to examine developmental changes and cultural differences in relationships between aggression and peer status was emphasized. 相似文献

The assessment of characteristic body features of Miss Poland beauty contest finalists compared with the control group, can contribute to recognising the contemporary ideal of beauty promoted by the mass media. The studies of Playboy models and fashion models conducted so far have been limited to the following determinants of attractiveness: body mass index, waist:hip ratio, and waist:chest ratio, which only partially describe the body shape. We compared 20 body features of the finalists of Miss Poland 2004 beauty contest with those of the students of Medical Academy in Bydgoszcz. Discriminant analysis showed that the thigh girth-height index, waist: chest ratio, height, and body mass index had the greatest discrimination power distinguishing the two groups. A model of Miss Poland finalists figure assessment is presented which allows one to distinguish super-attractive women from the control group. 相似文献

In paper [5] it was shown that a great part of model theory of logic with the generalized quantifier Q
x = there exist uncountably many x is reducible to the model theory of first order logic with an extra binary relation symbol. In this paper we consider when the quantifier Q
x can be syntactically defined in a first order theory T. That problem was raised by Kosta Doen when he asked if the quantifier Q
x can be eliminated in Peano arithmetic. We answer that question fully in this paper.I would like to thank Kosta Doen and Zoran Markovi who made valuable suggestions and remarks on a draft of this paper. 相似文献
