There are today a variety of patterns in the different cantons of Switzerland for regulating the teaching of RE. The Swiss system is based on a cooperation between Church and state which varies in relation to the history and character of the differing cantons. This allows for diversity in modes of delivering RE. In two cantons there is complete separation between church and state whereas in the majority there is some form of cooperation. State recognized religious communities (normally the Swiss Reformed and Roman Catholic Churches, but in Basel the Old Catholic Church and Jewish community also) are in charge of the RE in schools where it is taught by their representatives visiting the schools. Where state related RE is taught this is done by teachers in the school employed by the state. The presence of Turkish immigrants is raising problems for the teaching of RE in certain areas since Islam has not been traditionally state recognized. However, the inherent diversity of patterns within the 26 cantons allows considerable room for innovation feasible because there is generally an openness between the churches and from the state which facilitates this.  相似文献

In previous research on symmetry detection, factors contributing to orientational effects (axis and virtual lines connecting symmetrically positioned dots) and component processes (axis selection and pointwise evaluation) have always been confounded. The reason is the restriction to bilateral symmetry (BS), with pointwise correspondences being orthogonal to the axis of symmetry. In our experiments, subjects had to discriminate random dot patterns from symmetries defined by combining 12 axis orientations (every 15°) with seven reflection angles (0°, yielding BS, and three clockwise and counterclockwise 15° steps, yielding skewed symmetry, SS). In Experiment 1, with completely randomized trial order, a significant interaction between axis and skewing angle was obtained, indicating that classically observed orientational effects are restricted to BS and that the orientation of the pointwise correspondences is important. These basic findings were replicated in three subsequent experiments, which differed in that they used blocks containing patterns with the same axis (Experiment 2), virtual lines orientation (Experiment 3), or their combination (Experiment 4). Based on a comparison between the results obtained by these manipulations, we suggest a possible reason for the failure of preattentive symmetry detection in the case of dot patterns with SS.  相似文献

An irrelevant sequence of discrete auditory tokens disrupts serial recall markedly if successive tokens differ, but the disruption is less marked if the sound is repeated. However, the relation of stimulus mismatch and degree of disruption with serial recall seems to be modulated by organizational principles such as streaming by pitch and streaming by location. The current empirical work replicates the finding that the impact of changing sequences can be reduced if tokens are assigned to different locations in such a way as to form separate streams, each containing sequences of repeated tokens. This study shows that this phenomenon is not a consequence of reducing the number of tokens per stream.  相似文献

There is evidence indicating that an individual can learn a motor skill by observing a model practising it. In the present study we wanted to determine whether observation would permit one to learn the relative timing pattern required to perform a new motor skill. Also, we wanted to determine the joint effects of observation and of physical practice on the learning of that relative timing pattern. Finally, we were interested in finding whether there was an optimal type of model, advanced or beginner, which would lead better to observational learning. Data from two experiments indicated that observation of either a beginner or an advanced model resulted in modest learning of a constrained relative timing pattern. Observation also resulted in significant parameterization learning. However, a combination of observation followed by physical practice resulted in significant learning of the constrained relative timing pattern. These results suggest that observation engages one in cognitive processes similar to those occurring during physical practice.  相似文献

In this study, a priming Stroop paradigm was used to determine whether stereotype activation is unintentional. Priming conditions (priming/no‐priming) and the relationship between priming and target (consistent/inconsistent/no‐relation) were the independent variables; accuracy, reaction time and N400 amplitude were used as dependent variables. The reaction time revealed that stereotype activation is, to some extent, unintentional. Furthermore, the event‐related potenial (ERP) results showed that N400 amplitude was larger for inconsistent conditions than for consistent conditions. This result supported the notion that stereotype activation is an unintentional and automatic process.  相似文献

This study examined the relationship between physical contact and decision type in predicting “harm to save” behavior. Participants were assigned to making either a judgment or a choice involving moral dilemmas. All participants were presented with dilemmas that either required or did not require having physical contact with potential victims. Participants were asked to decide whether to sacrifice fewer people to save more (utilitarian responses) or not to do so and thus more people would die (deontological responses). The study sample included 345 participants who completed a set of self‐report measures. Results indicated an interaction between physical contact and decision type. In the choice condition only, participants reported significantly less utilitarian responses to the dilemmas that required having physical contact with the person to be harmed than to dilemmas that did not require physical contact. This difference was not found in the judgment condition. These results contribute to a greater understanding of the nature and potential malleability of human morality.  相似文献

This paper examines how a group member's individual‐targeted citizenship behavior (OCBI) and organization‐targeted citizenship behavior (OCBO) interact with a salient group‐level contextual variable, group cohesiveness, to foster positive change for that group member, starting with job self‐efficacy change, and followed by objective task performance change. Over a span of 6 months, we engaged in multilevel, multisource, multistage data collection and surveyed 587 members in 83 work groups. Our results indicate that a group member's OCBI, in comparison with OCBO, is more positively related to his or her job self‐efficacy change. Group cohesiveness was found to attenuate the relationship between a group member's OCBI and job self‐efficacy change, and conversely, to accentuate the relationship between a group member's OCBO and job self‐efficacy change. Furthermore, a group member's job self‐efficacy change mediated the interactive effects of the group member's OCBI and group cohesiveness (as well as the group member's OCBO and group cohesiveness) on his or her objective task performance change.  相似文献

This study examined when and how charitable advertisements could be effective in the context of child poverty. An experiment investigated the influences of message framing, image valence, and temporal framing on a charitable appeal. The results indicate that image valence enhances framing effects on advertising effectiveness of a charitable appeal when the image is congruent with the framed message, especially when the image and the message are presented negatively. A short‐term temporal frame facilitates effects of a negatively framed message with a negative pictorial presentation. Alternatively, a long‐term temporal frame increases advertising influences of a positively framed message with a positive pictorial image. Relevance for information processing of charity advertising is discussed.  相似文献
