Multibar figures provide a class of illusions that have been used by psychologists as well as by artists like Escher. For scientific purposes one needs as precise a definition and analysis as possible for these figures. A first attempt at this has been made by Cowan (1974) with the theory of braids. The present work points out some semantic and technical problems not dealt with by Cowan, and proposes a new language for the study of multibar figures. This language is shown to be incomplete, and some further problems are reviewed.  相似文献

Based on violation-of-expectation (VoE) paradigms, amazing cognitive competencies have been demonstrated in young infants, which could not be shown in toddlers or even preschoolers. This divergence might as much be caused by different research methods as by discontinuities in development. As looking-time measures are not readily applicable to older children, we suggest a new method that is suitable for children from two years of age onwards. In an empirical examination of this method, 26 children aged 2–7 years learned by trial and error to always find a target picture among a pair of pictures. Each target picture was an impossible version of the non-target picture. After reaching a learning criterion, children had to generalize the learned concept to pictures belonging to a different category. Results showed that even the youngest participants reached the learning criterion and were able to apply what they had learned to another category.  相似文献

Putative metacognition data in animals may be explained by non-metacognition models (e.g., stimulus generalization). The primary objective of the present study was to develop a new method for testing metacognition in animals that may yield data that can be explained by metacognition but not by non-metacognition models. Next, we used the new method with rats. Rats were first presented with a brief noise duration which they would subsequently classify as short or long. Rats were sometimes forced to take an immediate duration test, forced to repeat the same duration, or had the choice to take the test or repeat the duration. Metacognition, but not an alternative non-metacognition model, predicts that accuracy on difficult durations is higher when subjects are forced to repeat the stimulus compared to trials in which the subject chose to repeat the stimulus, a pattern observed in our data. Simulation of a non-metacognition model suggests that this part of the data from rats is consistent with metacognition, but other aspects of the data are not consistent with metacognition. The current results call into question previous findings suggesting that rats have metacognitive abilities. Although a mixed pattern of data does not support metacognition in rats, we believe the introduction of the method may be valuable for testing with other species to help evaluate the comparative case for metacognition.  相似文献

We tested the hypothesis that shared emotions, notably anger, influence the formation of new self-categories. We first measured participants' (N = 89) emotional reactions to a proposal to make university assessment tougher before providing feedback about the reactions of eight other co-present individuals. This feedback always contained information about the other individuals' attitudes to the proposals (four opposed and four not opposed) and in the experimental condition emotion information (of those opposed, two were angry, two were sad). Participants self-categorised more with, and preferred to work with, angry rather than sad targets, but only when participants' own anger was high. These findings support the idea that emotions are a potent determinant of self-categorisation, even in the absence of existing, available self-categories.  相似文献

Abstract

Numerous studies have demonstrated that planned health education and health promotion interventions are not particularly successful in bringing about behavioural change. It is suggested that the reasons for this are the fallacious theoretical assumptions underlying many intervention strategies and the failure to place sufficient emphasis on the context in which health-related behaviours occur. Studies of self-initiated behavioural change suggest that the antecedents of change are often events or processes which bring a previously routinised and unremarked behaviour into new focus.

This paper describes a preliminary test of a new model of behavioural change in which a group of lay people were recruited to act as paid interviewers on a food survey in their own area. The survey was particularly concerned with the consumption of high fibre foods. he and post-test measures of the interviewers' own food habits as compared with those of a control group indicated modest support for the proposed model. Implications of this study for health education and promotion are discussed.  相似文献

A multidisciplinary and global study of the evolutionary process of the universe in general and mankind in particular is proposed, drawing from both modern science, approached by taking into consideration its various interdependent aspects; and the study of western and eastern ancient traditions, which prove to have a common foundation that is the comprehension and the control of the evolutionary process itself.

Such a study will lead to the compilation of a “Corpus Unus” of the new science of the human, a science which does not belong to a race, a culture or an age, but is specific to the human being as such.

Such a science will imply the exploration of mankind and of the evolutionary process, and applying the results in a pragmatic way to the betterment of human beings, society, and universe.  相似文献

The purpose of the present study is to examine the applicability of a computer-generated, virtual animal to study animal cognition. Pigeons were trained to discriminate between movies of a real pigeon and a rat. Then, they were tested with movies of the computer-generated (CG) pigeon. Subjects showed generalization to the CG pigeon, however, they also responded to modified versions in which the CG pigeon was showing impossible movement, namely hopping and walking without its head bobbing. Hence, the pigeons did not attend to these particular details of the display. When they were trained to discriminate between the normal and the modified version of the CG pigeon, they were able to learn the discrimination. The results of an additional partial occlusion test suggest that the subjects used head movement as a cue for the usual vs. unusual CG pigeon discrimination.This contribution is part of the special issue ‘Animal Logics’ (Watanabe and Huber 2006)  相似文献

Seen through the quest for a new metaphysics, the visual arts were interpreted in the framework of the particular sense of progress that the generation of György Lukács developed in the first decade of the twentieth century. They saw Impressionism as the veritable symptom of the deficiencies of their age and dreamed of a great, solid, lasting new Hungarian culture which would transcend the fragmentariness, sociological interests, and ethereality of Impressionism. Although exhibitions of contemporary modernist art were organized in Budapest and the Nagybánya artists’ colony was in contact with the living French art, the nascent aesthetic theory, first of all that of Lukács, based the appreciation of Post-Impressionism on ideological considerations rather than the artistic particularities of the artists. Central to this aesthetic was the notion of greatness and a sense of metaphysics derived from German idealist philosophy and applied to the art of Cézanne, Gauguin, and the Budapest group The Seekers (founded in 1909, renamed, in 1911, as The Eight), all of whom were appreciated for features pointing in the direction of a new Classicism.  相似文献

In the dozen years since publication of Uttal’s fundamental paper, “‘Basic Black’ in Com-puter Interfaces for Psychological Research,” many changes have taken place in on-line real-time computing. A look at the basic wardrobe today reveals some striking changes and certain fundamental constants. Most of the interface elements in the wardrobe specified by Uttal are still commonplace in the fashion catalogs of real-time computing. However, they are offered now as fully integrated circuits, chips, or subsystems that are added by inserting a chip into a socket or a printed circuit board into a chassis. Missing in Uttal’s specification are the essential software tools for using the hardware of that wardrobe. The current real-time computing laboratory psychologist will find that the most significant elements in a really adaptable wardrobe are software tools.  相似文献

Automaticity: a new framework for dyslexia research?   总被引:16,自引:0,他引:16  
The performance of a group of 23 13-year-old dyslexic children was compared with that of same-age controls on a battery of tests of motor balance. A dual-task paradigm was used--subjects performed each test twice, once as a single task, and once as a dual task concurrently with a secondary task. Two alternative secondary tasks were used, the classic counting-backwards task and an auditory choice reaction task. Both secondary tasks were calibrated for each subject to ensure that their performance on the secondary task alone fell between pre-specified performance criteria. In all single-task conditions there was no difference between the performance of the two groups. By contrast, in 19 out of the 20 tests performed under dual-task conditions, the dyslexic group were significantly impaired, whereas the controls showed no impairment, thus resulting in significantly better performance by the control group than the dyslexic group. The sole exception was that the dyslexic children were not impaired on the easiest balance condition with the choice reaction task. Under the dual-task conditions the dyslexic children also performed worse than the controls on the secondary task. It is very hard to accommodate the findings within the traditional framework of a deficit specific to lexical skills. One plausible explanation of the results is that, unlike the controls, the dyslexic children need to invest significant conscious resources for monitoring balance, and thus their performance is adversely affected by any secondary task which serves to distract attention from the primary task. This need for "conscious compensation" suggests that for dyslexic children the skill of motor balance is poorly automatized. It is possible, therefore, that many of the reading deficits of dyslexic children are merely symptoms of a more general learning deficit--the failure to fully automatize skills.  相似文献

The Millennium Development Goals (MDGs) were criticised for failing to address the issue of governance, and the associated notions of responsibility and accountability. The Sustainable Development Goals, we argue, need to recognise the structural constraints facing poor countries – the power imbalances in the global economic system that limit their ability to promote the prosperity and well-being of their people, as was clearly brought out by the Commission on Global Governance for Health, of which we were both members [Ottersen, O. P., J. Dasgupta, C. Blouin, Paulo Buss, Virasakdi Chongsuvivatwong, Julio Frenk, Sakiko Fukuda-Parr, et al. 2014. “The Political Origins of Health Inequality: Prospects for Change.” Lancet 383: 630–667]. This article is divided into three parts. We begin by making the case for a global justice perspective which emphasises the responsibility – and hence also accountability – of international organisations and rule-making bodies. We next demonstrate the limitations of accountability mechanisms of the type adopted in the MDGs. We conclude by arguing for a new approach to accountability that may be better suited to the post-2015 era.  相似文献

Aggressive behavior is a highly complex construct that is very challenging to measure. While advancements in the assessment of aggression have been made, some fundamental problems persist. First, the operational definition of aggressive behavior and its various subtypes are frequently misinterpreted and lack sufficient conceptual clarity. Second, due to these definitional problems, assessment instruments frequently correspond to different conceptualizations of aggression. In the present review, we attempt to resolve these limitations by proposing a new taxonomic system of aggressive acts that (a) corresponds to a hybrid definition of aggressive behavior, and (b) increases conceptual clarity between subtypes of aggressive behavior. It is argued that this classification system will permit greater precision in the assessment of aggression and lead to the improvement of theories, diagnostic systems, and clinical interventions.  相似文献

Abstract

This article offers a reflection on conception, pregnancy, and the first mother–infant relationships of mothers with motoric and sensory disabilities. Based on more than 13 years of experience with women with motoric and sensory disabilities who had a desire for a child, the author analyzes this unusual situation from three different points of view: the medical help to procreate, meeting a partner for the mother, and the link with the initial maternal family, i.e. the mother’s mother. The last part concerns the possibility of the development of a mother–infant relationship when bodily function is lacking.  相似文献

In one view of implicit memory, priming arises from modification of preexisting representations; however, the role of such representations is currently in doubt following findings of implicit memory for newly formed associations. Closer consideration of studies reporting this effect, and of others that have failed to obtain it, suggests that such priming might result from the employment of explicit memory strategies. With measures designed to permit exclusion of such strategies, three experiments using lexical decision and stem-completion tasks found no evidence of truly implicit memory for unrelated pairs. Instead, priming was found only in those subjects (50% of the total in one experiment) who reported using explicit memory in stem completion. Contrary to previous conclusions, the results indicate a role for established representations in explaining implicit memory.  相似文献

The recent national concern over the failures of education has created a demand for new programs that will promote healthy psychological and personal growth. This article examines the present status of guidance theory and practice vis-à-vis humanistic education and suggests that the movement deliberately begs the question of values under the guise of promoting a new bag of virtues as educational objectives. It also discusses the need for a guidance theory based on a framework from developmental psychology rather than from theories of humanistic education.  相似文献

Re-work is a new treatment technique that follows the conventional Japanese approach, which includes rest and pharmacotherapy. The aim of re-work is to prevent repeated sick leave by helping individuals reflect on the reasons behind the sick leave and improve stress-related coping skills. Re-work participants prepare in an environment similar to their workplaces at a medical institution or a specialised public facility for several months before returning to work. As re-work is undertaken via group work, this has benefits beyond those which can be achieved by an individual alone. The reinstatement effects of re-work are now starting to be verified. Issues of interest for re-work include its unified concept-based programme, and the need to further verify its clinical efficacy and cost-effectiveness.  相似文献
