Although traditionally texture segmentation has been regarded as an automatic, preattentive process, participants confronted with texture segmentation in experimental settings (i.e., with brief presentation time and subsequent masking) are initially unable to perform the task. According to perceptual learning concepts, participants must learn to fine-tune their sensory channels before perception improves under restricted viewing conditions. The present article proposes an alternative perspective that emphasizes the role of the mask. Four experiments showed that the amount of observed learning depends on the structural and temporal homogeneity or heterogeneity of the mask. The authors suggest that learning consists of separating the task-relevant signal stemming from the texture from the task-irrelevant signal of the mask and of ignoring the mask. 相似文献

The present paper studies a specific way of addressing the question whether the laws involving the basic constituents of nature
are statistical. While most German physicists, above all Planck, treated the issues of determinism and causality within a
Kantian framework, the tradition which I call Vienna Indeterminism began from Mach’s reinterpretation of causality as functional
dependence. This severed the bond between causality and realism because one could no longer avail oneself of a priori categories
as a criterion for empirical reality. Hence, an independent reality criterion had to be sought, a problem which all three
physicists to be studied solved in different ways that were mainly conditioned by their different concepts of probability.
In order to prevent a dissipation of intuited facts, Mach had to resort to a principle of unique determination as his reality
criterion, especially when discussing the Principle of Least Action. Giving theories more independence, Boltzmann understood
atomism as property reduction to precisely defined theoretical entities and their interactions. While this served as a relative
reality criterion, he also advocated a constructivist one because atomism was already implied by our finitary reasoning power.
Finally, Exner contemplated the idea that all apparently deterministic laws are only a macroscopic limit of an irreducible
indeterminism, because by adopting the frequency interpretation, observable collectives could be considered as the real basic
entities.

When immigrant groups “misbehave”: The influence of perceived deviant behavior on increased threat and discriminatory intentions and the moderating role of right‐wing authoritarianism 下载免费PDF全文

In two studies, we tested the relationship between non‐immigrant individuals' perceptions of deviant behavior carried out by Muslims and foreigners and discriminatory intentions towards these outgroups. Based on a longitudinal and a representative cross‐sectional sample, we showed that two different types of perceived deviant behavior (Study 1, Muslims' unwillingness to integrate; and Study 2, foreigners' hostility towards the non‐immigrant majority group) are related to increased intergroup threat, which in turn is related to increased intentions to show passive discrimination (i.e., avoidance) towards these outgroups. In line with theorizing about an increased sensitivity for threat in authoritarian individuals, the relationship between perceptions of deviant behavior and threat was especially strong among high authoritarian individuals. Theoretical and practical implications of our results are discussed. 相似文献

The goal of the study was to examine the dimensionality of the Career Decision Self-Efficacy Scale Short Form (CDSES-SF, Betz et al. 1996). Integrating several previous findings from different cultures, we found that the bifactor structure of the CDSES-SF on a Hungarian sample of 649 respondents showed the best model fit. This structure includes a general CDSE factor covering 15 items and the original five specific factors (self-appraisal, occupational information, goal selection, planning, and problem solving) covering three items each. This short form of CDSES shows an acceptable model fit and appropriate reliability in terms of the Cronbach’s alpha and omega values. Regarding career decision self-efficacy, a large proportion of variance was explained by the general factor and to a smaller extent by the specific factors. These results can be considered as a first step in resolving the paradox of the dimensionality of CDSES-SF. 相似文献

The influence of defensivity, measured by validity scales of personality inventories (MMPI-K, FPI-R, GIESSEN-Test) on test results and psychotherapy outcome was studied in 309 patients treated with inpatient client-centered therapy. In general, psychotherapy patients exhibited low defensivity. 25% of patients, who denied psychopathology at admission, did so at discharge and to some extent at follow-up, demonstrating an ”especially good outcome” (means). Relative improvement (effect sizes), however, was significantly diminished in psychopathology scales and significantly enlarged in validity scales. – Results are discussed with regard to prior hypotheses about the influence of defensivity. 相似文献

The relation between school students' belief in a just world (BJW) and their bullying behavior was investigated in a questionnaire study. The mediating role of teacher justice was also examined. Data were obtained from a total of N = 458 German and Indian high school students. Regression analyses revealed that the more strongly students believed in a personal just world and the more they evaluated their teachers' behavior toward them personally to be just, the less bullying behavior they reported. Moreover, students with a strong BJW tended to evaluate their teachers' behavior toward them personally to be more just, and the experience of teacher justice mediated the relation between BJW and less bullying perpetration. This pattern of results was as expected and consistent across different cultural contexts. It persisted when neuroticism, sex, and country were controlled. The adaptive functions of BJW and implications for future school research are discussed. 相似文献

Seeing behind the surface: communicative demonstration boosts category disambiguation in 12‐month‐olds 下载免费PDF全文
In their first years, infants acquire an incredible amount of information regarding the objects present in their environment. While often it is not clear what specific information should be prioritized in encoding from the many characteristics of an object, different types of object representations facilitate different types of generalizations. We tested the hypotheses that 1‐year‐old infants distinctively represent familiar objects as exemplars of their kind, and that ostensive communication plays a role in determining kind membership for ambiguous objects. In the training phase of our experiment, infants were exposed to movies displaying an agent sorting objects from two categories (cups and plates) into two locations (left or right). Afterwards, different groups of infants saw either an ostensive or a non‐ostensive demonstration performed by the agent, revealing that a new object that looked like a plate can be transformed into a cup. A third group of infants experienced no demonstration regarding the new object. During test, infants were presented with the ambiguous object in the plate format, and we measured generalization by coding anticipatory looks to the plate or the cup side. While infants looked equally often towards the two sides when the demonstration was non‐ostensive, and more often to the plate side when there was no demonstration, they performed more anticipatory eye movements to the cup side when the demonstration was ostensive. Thus, ostensive demonstration likely highlighted the hidden dispositional properties of the target object as kind‐relevant, guiding infants’ categorization of the foldable cup as a cup, despite it looking like a plate. These results suggest that infants likely encode familiar objects as exemplars of their kind and that ostensive communication can play a crucial role in disambiguating what kind an object belongs to, even when this requires disregarding salient surface features. 相似文献
