The purpose of the present study was to confirm Beck’s six symptom categorization of depression through the most recent version of Beck Depression Inventory (BDI-II) by employing a confirmatory multidimensional scaling (MDS). This analysis indicates two independent dimensions in the BDI-II. The disturbance domain dimension relates to the domains wherein the disturbances occur, and validates Beck’s six symptom categorization dividing the items into disturbances in basic need-satisfaction, energy regulation, focused attention, regulation of emotion, motivation, and cognitive distortion in self-evaluation. The level of arousal dimension relates to how the disturbances are expressed, namely in an under-active, regular, or over-active manifestation. The MDS solution suggests 18 (6 × 3) symptom areas of depression, and may serve as a guide for constructing additional items. 相似文献

We investigated whether adult learners' knowledge of phonotactic restrictions on word forms from their first language impacts their ability to use statistical information to segment words in a novel language. Adults were exposed to a speech stream where English phonotactics and phoneme co-occurrence information conflicted. A control where these did not conflict was also run. Participants chose between words defined by novel statistics and words that are phonotactically possible in English, but had much lower phoneme contingencies. Control participants selected words defined by statistics while experimental participants did not. This result held up with increases in exposure and when segmentation was aided by telling participants a word prior to exposure. It was not the case that participants simply preferred English-sounding words, however, when the stimuli contained very short pauses, participants were able to learn the novel words despite the fact that they violated English phonotactics. Results suggest that prior linguistic knowledge can interfere with learners' abilities to segment words from running speech using purely statistical cues at initial exposure. 相似文献

In this article, the formation and transformation of knowledge and the role of designs for learning will be elaborated and
discussed in relation to the introduction of national curricula and school textbooks during the beginning of the industrialized
era vs. the introduction of individual curricula and new digital learning resources in the post-industrialized era of globalization
and multiculturalism. Quite different teaching and learning strategies have been emphasized, which I will call here “designed
information and teaching” vs. “designs for learning”. It seems obvious that our current society is in a stage of change that
requires a new understanding of knowledge, learning and identity formation. The new position and role of the learner underlines
the productive and constructive aspect of learning. Pupils not only read texts, they also produce texts, pictures, film and
music and they compile and edit virtual texts. Multimodal texts, as well as the information flow of the Internet, are the
consequences of, and at the same time a vehicle for, new social patterns. “Learning Design Sequences” (LDS) is introduced
as a theoretical map for the purpose of analyzing critical incidents in (a creative) learning process, using different genres,
modes and media in a process of meaning-making.

It has been reported that the overall shapes of spatial categorical patterns of projective spatial terms such as above and below are not influenced by the rotation of a reference object on a two-dimensional (2D) upright plane. However, is this also true in three-dimensional (3D) space? This study shows the dynamic aspects of the apprehension of projective spatial terms in 3D space by detailing how the rotation of a reference object with an inherent front influences the apprehension of projective spatial terms on a level plane by mapping their spatial categorical patterns. The experiment was designed to examine how spatial categorical patterns on a level plane changed with the rotation of a reference object with an inherent front in 3D computer graphics space. We manipulated the rotation of a reference object with an inherent front at three levels (0°, 90°, and 180° rotations) and examined how such manipulation changed the overall spatial categorical patterns of four basic Japanese projective spatial terms: mae, ushiro, hidari, and migi (similar to in front of, behind, to the left of, and to the right of in English, respectively). The results show that spatial term apprehension was affected by the rotation of the reference object in 3D space. In particular, rotation influenced the mae–ushiro and hidari–migi systems differently. The results also imply that our understanding of projective spatial terms on a level plane in 3D space is affected dynamically by visual information from 3D cues. 相似文献

This paper investigates the dichotomous Mokken nonparametric item response theory (IRT) axioms and properties under incomparabilities among latent trait values and items. Generalized equivalents of the unidimensional nonparametric IRT axioms and properties are formulated for nonlinear (quasi-ordered) person and indicator spaces. It is shown that monotone likelihood ratio (MLR) for the total score variable and nonlinear latent trait implies stochastic ordering (SO) of the total score variable, but may fail to imply SO of the nonlinear latent trait. The reason for this and conditions under which the implication holds are specified, based on a new, simpler proof of the fact that in the unidimensional case MLR implies SO. The approach is applied in knowledge space theory (KST), a combinatorial test theory. This leads to a (tentative) Mokken-type nonparametric axiomatization in the currently parametric theory of knowledge spaces. The nonparametric axiomatization is compared with the assumptions of the parametric basic local independence model which is fundamental in KST. It is concluded that this paper may provide a first step toward a basis for a possible fusion of the two split directions of psychological test theories IRT and KST. 相似文献

Successful interaction with the environment depends upon our ability to retain and update visuo-spatial information of both front and back egocentric space. Several studies have observed that healthy people tend to show a displacement of the egocentric frame of reference towards the left. However representation of space behind us (back space) has never been systematically investigated in healthy people. In this study, by means of a novel visual imagery task performed within a virtual reality environment, we found that representation of right back space is perceived as smaller than the left. These results suggest that there is a selective compression or distortion for mental representation related to the right space behind us. 相似文献

In this study, the spatial limits of referred touch to a rubber hand were investigated. Participants rated the strength of the perceived illusion when the rubber hand was placed in one of six different spatial positions (at a distance of 17.5-67.5cm horizontal from the participant's own hand). The results revealed a significant nonlinear relationship in the strength of the illusion, with the strongest ratings given when the two hands were closest; decaying significantly after a distance of 30cm. The time taken to elicit the illusion followed a similar trend. These results may reflect the response properties of bimodal visuo-tactile cells encoding peripersonal space around the hand. 相似文献

We consider the binary relations of parallelism and convergence between lines in a 2-dimensional affine space. Associating with parallelism and convergence the binary predicates P and C and the modal connectives [P] and [C], we consider a first-order theory based on these predicates and a modal logic based on these modal connectives. We investigate the axiomatization/completeness and the decidability/complexity of this first-order theory and this modal logic. 相似文献
