Experiential structuralism is a new theory of cognitive organization and growth. It postulates that the cognitive system is organized into six autonomous capacity spheres: the quantitative-relational, the qualitative-analytic, the imaginal-spatial, the causal-experimental, the verbal-propositional, and the metacognitive-reflecting. These capacities were called experiential because they are experimentally documented, they reflect the organization of the persons' experience and the - subjective - experience the persons have about this organization. Thus it was proposed that a set of specific cognitive abilities may be integrated into a general capacity under the guidance of four principles. Namely, the principles of (1) domain specificity, (2) formal-procedural specificity, (3) symbolic bias, and (4) subjective distinctness of capacities. It was argued that this theory resolves some of the problems related to the competence-performance dispute better than the other neo-Piagetian theories. It seems to succeed in this regard because it postulates mechanisms directly linking performance variations with systematic variations in the organization of the cognitive system. However, the neo-Piagetian theories, though they did not define capacities, did propose notions able to causally explain the construction of autonomous capacities. These notions were integrated into a common model able to explain the generation of capacities. Overall, then, the present article attempts to integrate traditional differential and cognitive-developmental psychology into a common theory. 相似文献

The integration of formal operations in a lattice–INRC group structure was tested in young adults. For this purpose the equilibrium in balance, the combination of liquids and the conservation of motion tasks were employed. To test the possibility of differential integration because of differences in developmental history, the factors of education and sex were manipulated systematically. Thus, four groups were constituted of educated males, educated females, uneducated males, and uneducated females, forming a total of 40 subjects. The results revealed a consistent patterning of performance on the three tasks across groups and across subjects which is in disagreement with the Piagetian model. Education and sex were important factors in respect to formal thought attainment. A theory of formal thought spheres is formulated to account for the patterning obtained and the implications for further research discussed. 相似文献

The psychophysical features of the transition from the pure heat to the heat pain range were studied in 25 healthy subjects (mean age 28.8 years). Thirty short heat stimuli from ?1.6° C to + 1.6° C relative to the pain threshold were applied to the thenar of the left hand with an apparatus containing a Peltier thermode (nine different temperatures at 0.4°C intervals). The subjects rated the sensation intensity on a visual analogue scale. The resulting stimulus/sensation intensity relations could be explained equally well (same goodness of fit) by a model with a power function (PF) and by a model with two linear regression lines (TLR), one for stimulus intensities below and one for those above the pain threshold and intersecting at the pain threshold. The slopes of the TLR model were significantly larger above the pain threshold than below it. The PF model produced exponents between 1.8 and 1.9. We conclude that to describe the transition area, it is sufficient to use simple linear models for both the pure heat and the heat pain ranges. 相似文献

In this paper Modern Essentialism is used to solve a problem of individuation of spacetime points in General Relativity that has been raised by a New Leibnizian Argument against spacetime substantivalism, elaborated by Earman and Norton. An earlier essentialistic solution, proposed by Maudlin, is criticized as being against both the spirit of metrical essentialism and the fundamental principles of General Relativity. I argue for a modified essentialistic account of spacetime points that avoids those obstacles. 相似文献

The article seeks to understand Hannah Arendt's political thinking by relating it to an issue which is crucial to the thinking of the later Heidegger, i.e., the problem of originality ( Anfänglichkeit) and history. In opposition to Hegel's thesis of the end of art, Heidegger envisages in great art such as Hölderlin's poetry a new origin of thinking and history. The end of art, which Hegel holds to be necessary, is in Heidegger's view to be overcome precisely because art, for him, entails an origin which is not a Not yet of a teleological perfection in Hegel's sense, but a Not yet of a future history. However, Heidegger's orientation towards a pure origin qua future leads him to poietically escape the realm of the Political and the questions of praxis and practical rationality.Like Heidegger, Arendt is taken with the problem of origin; but in contrast to her former teacher, she tries to regain what Heidegger thought he could leave, viz., the dimension of the genuine Political and of acting. The original sense of acting (for Arendt, the capability of human beings to make a new beginning) can be observed in the Greek polis as well as in the American Revolution in modern times: The revolutionary act of a total new beginning elucidates, according to Arendt, what acting means in the full and truly political sense. However, Arendt's notion of an epochal beginning seems one-sided, and her abstract concept of acting seems to foster a mere actionism and anarchy. Therefore, contrary to Arendt's claims, the concept of the Political which she shapes in accordance with the extraordinary experiences of an epochal acting has apolitical consequences. The task of thinking after Heidegger and Arendt thus remains one of determining the political character of action in a convincing manner. In this respect, the paper pleads for a rethinking of Hegel's concept of ethical life ( Sittlichkeit). 相似文献

Previous research in group decision making has found that in situations of a hidden profile (i.e. the best choice alternative is hidden from individual members as they consider their pre‐discussion information), unshared information is disproportionately neglected and sub‐optimal group choices are highly likely. In an experimental study, three‐person groups decided which of three candidates to select for a professorial appointment. We hypothesised that minority dissent in pre‐discussion preferences improves the consideration of unshared information in groups and increases the discovery rate of hidden profiles. As predicted, consideration of unshared information increased with minority dissent. The expectation of an improvement of group decision quality was partially supported. In diversity groups (i.e. each member prefers a different alternative) consideration of unshared information and group decision quality was significantly higher than in simple minority groups. Results are discussed in the light of theories of minority influence. The benefits of using the hidden profile paradigm with minority and diversity groups for theory development in the area of group decision making are highlighted.
