320 Croatian female students (M=20.4 yr.) were recruited to examine the validity and reliability of figural scales using different numbers of stimuli (3, 5, 7, and 9) and different serial presentation (serial and nonserial order). A two-way analysis of variance (4 numbers x 2 orders of stimuli) was performed on ratings of current self-size and ideal size as dependent variables. Analysis indicated a significant main effect of number of stimuli. This, together with post hoc tests indicated that ratings were significantly different for a scale of three figures from scales of more figures, which in turn did not differ among themselves. Main effects of order of stimuli, as well as the interaction, were not significant. The results support the hypothesis that the optimal number of figures on a scale is seven plus (or minus) two. 相似文献

This study examined whether a distinction between aggressive and nonaggressive antisocial behavior can be empirically verified in a large (254 girls and 254 boys) nonclinical (community) sample of Dutch adolescents between 12 and 18 years old. The results of confirmatory factor analysis for both boys and girls shows that aggressive and nonaggressive antisocial behaviors do not represent a single underlying dimension, but two separate constructs with moderate independence among them. These findings suggest that the conceptualization of adolescent antisocial behavior as a one-dimensional phenomenon is of questionable utility and supports growing evidence that aggressive antisocial behavior is distinct from other forms of antisocial behavior. 相似文献

We prove that every finitely axiomatizable extension of Heyting's intuitionistic logic has a corresponding cut-free Gentzen-type formulation. It is shown how one can use this result to find the corresponding normalizable natural deduction system and to give a criterion for separability of considered logic. Obviously, the question how to obtain an effective definition of a sequent calculus which corresponds to a concrete logic remains a separate problem for every logic. 相似文献

This paper offers an ethnomethodological clarification of Husserl's concepts of Galilean physics and regressive inquiry. It employs the reader's textual-practical operationalization of these concepts. With the use of a simple optical prism as a perspicuous case of a scientific instrument, the reader will be asked and instructed to make a self-reflexive inquiry into the practical contingencies of the prismatic field of reflection. The reader will discover that the geometric structures of the reflective field of the prism is an achievement and formalization of the reader's own operatlonalizations. I named these discoverable discovering operationspraxioms or practical axioms — the pre-scientific contingencies of the geometric structures of prismatic reflection.I would like to thank Mike Lynch, Eric Livingston, George Psathas and Shelley Schweizer-Bjelic for their comments. 相似文献

During 1745–1755 Bo?kovi? explicitly used the concept of scientific theory in three cases: the theory of forces existing in nature, the theory of transformations of geometric loci, and the theory of infinitesimals. The theory first mentioned became the famous theory of natural philosophy in 1758, the second was published in the third volume of his mathematical textbook Elementorum Universae Matheseos (1754), and the third theory was never completed, though Bo?kovi? repeatedly announced it from 1741 on. The treatment of continuity and infinity in natural philosophy, geometry and infinitesimal analysis brought about inter‐theory relations in Bo?kovi?'s work during his Roman period. The two constructed theories of Bo?kovi?, the theory of forces and the theory of geometric transformations, directly influenced the idea for the construction of his third theory. These written theories refer to understanding and effective application of continuity and infinity in natural philosophy and geometry, and this task, according to Bo?kovi?, requires methodological support from the theory of infinitesimals. 相似文献

A Myoclonus Versus Tic Checklist facilitates making this vexing differential diagnosis. Although it appears to be a valuable tool for clinical, educational, and research purposes, psychometric characterization of the Myoclonus Versus Tic Checklist is needed. 相似文献

Some features of linear perspective images may look distorted. Such distortions appear in two drawings by Jan Vredeman de Vries involving perceived elliptical, instead of circular, pillars and tilted, instead of upright, columns. Distortions may be due to factors intrinsic to the images, such as violations of the so-called Perkins's laws, or factors extrinsic to them, such as observing the images from positions different from their center of projection. When the correct projection centers for the two drawings were reconstructed, it was found that they were very close to the images and, therefore, practically unattainable in normal observation. In two experiments, enlarged versions of images were used as stimuli, making the positions of the projection centers attainable for observers. When observed from the correct positions, the perceived distortions disappeared or were greatly diminished. Distortions perceived from other positions were smaller than would be predicted by geometrical analyses, possibly due to flatness cues in the images. The results are relevant for the practical purposes of creating faithful impressions of 3-D spaces using 2-D images. 相似文献
