K olehmainen , K. Apparent size as a determiner of figural after-effects. II. Scand. J. Psychol . 1968, 9, 237—240.—A brightly illuminated circle (TF) was flashed at distance d . The subject projected the after-image of TF on a screen placed at distance d/2, and fixated the after-image, which appeared to be half the size of the stimulus figure. Then TF and a comparison circle (CF) of equal size were shown, faintly illuminated, at distance d . A clear-cut figural after-effect occurred TF was perceived to be larger. It is suggested that TF appeared dimmer after the fixation and was perceived to be farther away than CF. As a consequence of this TF looked larger.  相似文献

K olehmainen , K. Apparent size as a determiner of figural after-effects. 111. Scand. J. Psychol ., 1969, 10 , 71–73.—Two rectangles were presented as an inspection figure in a gradient drawing, one appearing to be behind the fixation point and the other in front of it, because of the gradient effect. Test figures (circles) appeared to differ in size after inspection of this pattern. It is argued that this result supports the explanation suggested for the results of the earlier experiments in the present series (1968) that size-changes of the test figures in this kind of situation are connected with an after-effect in the third dimension.  相似文献

K olehmainen , K. Apparent size as a determiner of figural after-effects. I. Scand. J. Psychol ., 1968, 9, 230–236.—Apparent size as a determiner of figural after-effects (FAE) was studied by presenting the inspection figures in drawings which appeared three-dimensional because of gradient-effects. Significant FAEs were found. It is argued that apparent size does not determine FAE directly but an apparent decrement in the size of the test figure is connected to an after-effect in third-dimension.  相似文献

Two experiments are reported. In the first, the influence of stimulus size on apparent weight, i.e., the size-weight illusion, was scaled. The relationship between heaviness and size could be described by a simple power function. In the second experiment it was demonstrated that the illusory weight differences give rise to aftereffects. The size of the after-effect increased monotonically with the amount of apparent weight difference.  相似文献

D ureman , I. Factors influencing the apparent velocity of visual movement after-effects. Scand. J. Psychol ., 1962, 3 , 132–136.—Estimates of speed of apparent visual movement after-effects (VMAE) were undertaken with induction speed varied in five logarithmic steps from 9° to 144° per second. Two alternative test intervals 0.5 and 1.0 sec were used for intermittent inspection of a stationary target. At both inspection intervals VMAE-velocity estimates were found to vary in a systematic way with induction speed. Comparing values from the two test intervals, the 0.5 sec interval was found to yield significantly higher speed of VMAE than the 1.0 sec interval.  相似文献

B jörkman M. Feedforward and feedback as determiners of knowledge and policy: notes on a neglected issue. Scand. J. Psychol . 1972, 13 , 152–158.—Studies of cognitive learning should distinguish between acquisition of knowledge and policy formation. Two learning operators, feedforward, that is, task information by instructions, and feedback must also be taken into account. This double aim requires experimenters to analyze and relate two sets of data: subjective estimates about the task learned and predictions of outcomes. A broader approach is thus needed with a focus on how policy is related to knowledge, how these processes depend on feedback and feedfonvard and how the latter two interact in producing knowledge and policy.  相似文献

L'étude des facteurs culturels en matière de perception et L'étude des facteurs culturels en matière de personnalité ont été, jusqu' à présent, relativement séparées. L'A. propose un modèle qui permet d'intégrer les deux domaines en faisant L'hypothèse d'une relation indirecte entre L'ecologie et les réponses perceptives et d'une relation directe qui correspondrait à celle mise en évidence par les études de laboratoires classiques entre fréquence de L'expérience passée et réponse perceptive. Pour valider le modèle, L'A. utilise les données de deux expériences qui ont été réalisées avec des sujets Temne et Esquimaux et qui portent L'une sur la reproduction de figures ambiguës présentées au tachistoscope et L'autre sur la résolution de rivalités binoculaires.  相似文献

L'A présente les résultats d'un certain nombre d'expéricnces qui ont été réalisées avec les Progressive Matrices de Raven en Afrique et en Grande-Bretagne. II a utilisé des méthodes d'analyse factorielle pour comparer la difficulté des items d'une culture à L'autre et pour décrire les différentes stratégies individuelles des répondants. Les principales conclusions sont les suivantes : 1. Les tests qui utilisent des dessins et des figures sont des instruments complexes qui entraînent des biais caractéristiques dans les réponses. 2. Ces biais jettent un certain doute sur L'idée qu'il peut exister des tests libres de toute influence culturelle ou même dans lesquels les facteurs culturels seraient réduits. 3. Les résultats sont mis en liaison avec une théorie de L'intelligence qui met L'accent sur le rôle du système de valeurs en vigueur dans une société donnée; le système de valeurs dètermine en partie la nature des capacités humaines et leurs rclations.  相似文献

In two experiments with geometrical figures as stimuli, constructed in order to generate perceptual variation of roundness and height, four multidimensional scaling methods were compared, two metric and two nonmetric. The methods gave similar solutions. The fact that the solutions could be interpreted in accordance with expectations, points to the validity of the methods.  相似文献

K ünnapas , T. M. Measurement of the intensity of an underlying figural process. A methodological study. Scand. J. Psychol ., 1961, 2 , 174–184.—A method is proposed for studying the intensity of the figural process underlying the well-known phenomenon of figural fluctuations. A metric model is presented according to which a measure of the intensity of the underlying process is obtained in units of dispersion. The model is illustrated by an experimental example. An equation is given which is analogous to that of the damped harmonic vibration. Four parameters are involved in this equation. A technique for determining the parameters is developed. Very good agreement between theoretical and empirical scale values demonstrates the applicability of the proposed method.  相似文献

Abstract— The two experiments reported explored a bias toward symmetry in judging identity and orientation of indeterminate two-dimensional shapes. Subjects viewed symmetric and asymmetric filled, random polygons and described, "what each figure looks like" and its orientation. Viewers almost universally interpreted the shapes as silhouettes of bilaterally symmetric three-dimensional (3-D) objects. This assumption of 3-D symmetry tended to constrain perceived vantage of the identified objects such that symmetric shapes were interpreted as straight-on views, and asymmetric shapes as profile or oblique views. Because most salient objects in the world are bilaterally symmetric, these findings are consistent with the view that assuming 3-D symmetry can be a robust heuristic for constraining orientation when identifying objects from indeterminate patterns.  相似文献

The starting point of the investigation was the field dependence-independence construct as measured with the Embedded Figures Test of H.A. Witkin. An overview of the research on the information-processing strategies in solving the items of this test was converging into a theory in which strategies for a successful solution can be located on a bipolar dimension with at one extreme a simultaneous strategy and at the other extreme a successive strategy. A new administration procedure for evaluating the use of four solution strategies was developed: the simultaneous, the successive, the extemalized-successive and the global-manipulatory strategy. Based on the prediction that the use of strategies was related to sex and age, we carried out an experiment involving groups of ten boys and ten girls of 5, 6 and 7 years of age, who were given eight tasks with the new administration procedure. No. significant difference was found between boys and girls. However, significant differences existed in strategy profiles in six of the eight tasks between the three age groups.  相似文献

B erglund , B., B erglund , U., E kman , G. & F rankenhaeuser , M. The influence of auditory stimulus intensity on apparent duration. Scand J. Psychol ., 1969, 10 21–26.— apparent duration of an auditory signal of 1000 C/S was measured by the method of magnitude estimation. Ten different stimulus intensities ranging from 57 to 104 dB were used in combination with three different durations: 50, 250, and 500 msec. The results showed that the apparent duration of the signal grew as a logarithmic function of stimulus intensity. These results are consistent with the hypothesis relating apparent duration to activation level as well as with results of similar experiments involving electrical and vibrotactile stimulation.  相似文献

The special case of purely qualitative multidimensional similarity was studied in four experiments concerned with simple geometric figures. A previously proposed equation did not describe the relation between subjective similarity and angular separation of the percept vectors. Factor analyses indicate that in the 'homogeneous' experiments (with parallelogram figures) there were two pairs of inversely related subjective attributes which vary as a function of the difference between the horizontal and vertical axes of the parallelogram, and that in the 'heterogeneous' experiments (different figures) there were four main independent subjective attributes.  相似文献

The idea of Mitigation incorporates the conviction that though the amount or severity of punishment is primarily to be determined by reference to the General Aim, yet Justice requires that those who have special difficulties to face in keeping the law which they have broken should be punished less.  相似文献
