Usually, rhetoric is supposed to provide a model of law which describes legal interactions as volitive, arbitrary, and void of any system. However, the Mainz School, founded by Theodor Viehweg, proves the contrary: without referring to any metaphysics, such as consensus or auditoire universel, it seeks to discover the systematic character and the more or less flexible structures of legal rhetoric.  相似文献

People with tumours in specific brain sites might face difficulties in tasks with different linguistic material. Previous lesion-symptom mapping studies (VLSM) demonstrated that people with tumours in posterior temporal regions have more severe linguistic impairments. However, to the best of our knowledge, preoperative performance and lesion location on tasks with different linguistic stimuli have not been examined. In the present study, we performed VLSM on 52 people with left gliomas to examine whether tumour distribution differs depending on the tasks of the Aachen Aphasia Test. The VLSM analysis revealed that single-word production (e.g. object naming) was associated with the inferior parietal lobe and that compound and sentence production were additionally associated with posterior temporal gyri. Word repetition was affected in people with tumours in inferior parietal areas, whereas sentence repetition was the only task to be associated with frontal regions. Subcortically, word and sentence production were found to be affected in people with tumours reaching the arcuate fasciculus, and compound production was primarily associated with tumours affecting the inferior longitudinal and inferior fronto-occipital fasciculus. Our work shows that tasks with linguistic stimuli other than single-word naming (e.g. compound and sentence production) relate to additional cortical and subcortical brain areas. At a clinical level, we show that tasks that target the same processes (e.g. repetition) can have different neural correlates depending on the linguistic stimuli used. Also, we highlight the importance of left temporoparietal areas.  相似文献

There is ample evidence that multimedia learning is challenging, and learners often underutilize appropriate cognitive processes. Previous research has applied prompts to promote the use of helpful cognitive processing. However, prompts still require learners to regulate their learning, which may interfere with learning, especially in situations where cognitive demands are already high. As an alternative, implementation intentions (i.e. if-then plans) are expected to help regulate behaviour automatically due to their specific wording, thereby offloading demands. Accordingly, this study aimed at investigating whether implementation intentions compared with prompts improve learning performance, especially under high cognitive load. Students (N = 120) learned either in a control condition without instructional support, with prompts, or with implementation intentions. Within each condition, half of the participants studied the multimedia instruction under conditions of either high or low cognitive load, which was experimentally manipulated by instructing them to perform one of two secondary tasks. In line with our hypotheses, the results showed that under low cognitive load, both prompts and implementation intentions led to better learning than the control condition. By contrast, under high cognitive load, only implementation intentions promoted learning. Thus, implementation intentions are an efficient means to promote learning even under challenging circumstances.  相似文献

This study was designed to examine the portrayal of women in advertisements in a general interest magazine (i.e., Time) and a women's fashion magazine (i.e., Vogue) over the last 50 years. The coding scheme used for this analysis was based on the one developed by sociologist Erving Goffman in the 1970s, which focuses primarily on the subtle and underlying clues in the picture content of advertisements that contain messages in terms of (stereotypical) gender roles. The results of this study show that, overall, advertisements in Vogue, a magazine geared toward a female audience,depict women more stereotypically than do those in Time, a magazine with the general public as a target audience. In addition, only a slight decrease in the stereotypical depiction of women was found over time, despite the influence of the Women's Movement.  相似文献

Lay theories about willpower—the belief that willpower is a limited versus nonlimited resource—affect self‐control and goal striving in everyday life (Job, Dweck, & Walton, 2010). Three studies examined whether willpower theories also relate to people's subjective well‐being by shaping the progress they make toward their personal goals. A cross‐sectional (Study 1) and two longitudinal studies (Studies 2 and 3) measured individuals’ willpower theories and different indicators of subjective well‐being. Additionally, Study 3 measured goal striving and personal goal progress. A limited theory about willpower was associated with lower subjective well‐being in a sample of working adults (Study 1, N = 258). Further, a limited theory predicted lower levels of well‐being at a time when students faced high self‐regulatory demands (Study 2, N = 196). Study 3 (N = 157) replicated the finding that students with a limited theory experienced lower well‐being in phases of high self‐regulatory demands and found that personal goal progress mediated this relationship. Results suggest that the belief that willpower is based on a limited resource has negative implications not only for self‐control but also for personal goal striving and subjective well‐being.  相似文献

Sleep is considered to support the formation of skill memory. In juvenile but not adult song birds learning a tutor's song, a stronger initial deterioration of song performance over night‐sleep predicts better song performance in the long run. This and similar observations have stimulated the view of sleep supporting skill formation during development in an unsupervised off‐line learning process that, in the absence of external feedback, can initially also enhance inaccuracies in skill performance. Here we explored whether in children learning a motor sequence task, as in song‐learning juvenile birds, changes across sleep after initial practice predict performance levels achieved in the long run. The task was a serial reaction time task (SRTT) where subjects had to press buttons which were lighted up in a repeating eight‐element sequence as fast as possible. Twenty‐five children (8–12 years) practised the task in the evening before nocturnal sleep which was recorded polysomnographically. Retrieval was tested on the following morning and again 1 week later after daily training on the SRTT. As expected, changes in response speed over the initial night of sleep were negatively correlated with final performance speed after the 1‐week training. However, unlike in song birds, this correlation was driven by the baseline speed level achieved before sleep. Baseline‐corrected changes in speed or variability over the initial sleep period did not predict final performance on the trained SRTT sequence, or on different sequences introduced to assess generalization of the trained behaviour. The lack of correlation between initial sleep‐dependent changes and long‐term performance might reflect that the children were too experienced for the simple SRTT, possibly also favouring ceiling effects in performance. A consistent association found between sleep spindle activity and explicit sequence knowledge alternatively suggests that the expected correlation was masked by explicit memory systems interacting with skill memory formation.  相似文献

In a longitudinal study, 137 children at the age of 4 years were tested for media sign literacy, intelligence, and several precursors of academically relevant skills, such as phonological awareness and preschool quantity-number competencies. The children were tested four times over two years, measuring the development of these skills every six months. The purpose of the study was to explore whether children’s level of media sign literacy helps them acquire academically relevant symbolic skills like reading and mathematical competencies. The results indicate that media sign literacy as well as intelligence predict mathematical and linguistic competencies. Longitudinal findings indicate that children with higher levels of media sign literacy also achieve higher scores in precursors of mathematical and reading and writing skills, and structural equation modeling revealed a rich interconnectedness between media sign literacy and intelligence. Media sign literacy had a direct and significant effect on mathematical competencies at measurement point 2 and indirect effects on the precursors of reading and writing skills at measurement point 4.  相似文献

This empirical paper investigates how individuals conceptualize causes of career transitions, focusing on the three European countries of Austria, Serbia, and Spain in comparison to the USA and China. Collectively, these countries represent four separate cultural regions according to Schwartz. Semi‐structured interviews were conducted with members of three occupational groups: business people, nurses, and blue‐collar workers. Analysis of the data generates greater insight about the existence of both region‐specific patterns as well as potentially universalistic tendencies regarding perceived causes of career transitions. Perceptions of internal (to the person) drivers of career transitions as activating forces are evident in all five countries. The overall results support contemporary notions of occupational careers that are highly individualized, a characterization strongly emphasized in the current career literature. In the European culture clusters, causes of career transitions are attributed internally and externally. China, representing the Confucian cultural region, stresses external causes for career transitions. By contrast, in the USA only internal attributions of causes are reported.  相似文献
