This research examined the influence of negative political advertising frames on the thoughts and feelings people generate in response to campaign advertising. Preparing and conducting this investigation involved the use of a multiple‐method strategy. Content analysis identified two advertising frames (i.e., candidate theme and ad hoc issue advertisements) and two experiments separately induced political cynicism and politician accountability. Three hundred and sixty people participated in the experimental studies, in which they read and responded, using a thought‐listing technique, to candidate theme or ad hoc issue negative advertisements. Results demonstrated that participants were more likely to generate cynical comments and hold politicians accountable for the country's ills when reading candidate theme advertisements than ad hoc issue advertisements. The results indicate that this contributes to a political climate of cynicism and may function to erode the electorate's overall trust in government.  相似文献

The aim of this article is to discuss the nature of disagreement in scientific ontologies in the light of case studies from biology and cognitive science. I argue that disagreements in scientific ontologies are usually not about purely factual issues but involve both verbal and normative aspects. Furthermore, I try to show that this partly non-factual character of disagreement in scientific ontologies does not lead to a radical deflationism but is compatible with a “normative ontological realism.” Finally, I argue that the case studies from the empirical sciences challenge contemporary metaontological accounts that insist on exactly one true way of “carving nature at its joints.”  相似文献

A wealth of comparative data has been accumulated over the past decades on how animals acquire and use information about the physical world. Domestic dogs have typically performed comparably poorly in physical cognition tasks, though in a recent study Kundey et al. (Anim Cogn 13:497–505, 2010) challenged this view and concluded that dogs understand that objects cannot pass through solid barriers. However, the eight subjects in the study of Kundey et al. may have solved the task with the help of perceptual cues, which had not been controlled for. Here, we tested dogs with a similar task that excluded these cues. In addition, unlike the set-up of Kundey et al., our set-up allowed the subjects to observe the effect of the solid barrier. Nevertheless, all 28 subjects failed to solve this task spontaneously and showed no evidence of learning across 50 trials. Our results therefore call into question the earlier suggestion that dogs have, or can acquire, an understanding of the solidity principle.  相似文献

Numerous recent studies have investigated how animals solve means-end tasks and unraveled considerable variation in strategies used by different species. Domestic dogs (Canis familiaris) have typically performed comparably poorly in physical cognition tasks, but a recent study showed that they can solve the onoff condition of the support problem, where they are confronted with two boards, one with a reward placed on it and the other with a reward placed next to it. To explore which strategies dogs use to solve this task, we first tested 37 dogs with the onoff condition tested previously and then tested subjects that passed this condition with three transfer tasks. For the contact condition, the inaccessible reward was touching the second board. For the perceptual containment condition, the inaccessible reward was surrounded on three sides by the second board, but not supported by it, whereas for the gap condition, discontinuous boards were used. Unlike in the previous study, our subjects did not perform above chance level in the initial trials of the onoff condition, but 13 subjects learned to solve it. Their performance in the transfer tasks suggests that dogs can learn to solve the support problem based on perceptual cues, that they can quickly adopt new cues when old ones become unreliable, but also that some apparently inherent preferences are hard to overcome. Our study contributes to accumulating evidence demonstrating that animals typically rely on a variety of perceptual cues to solve physical cognition tasks, without developing an understanding of the underlying causal structure.  相似文献

Understanding the relation between objects and their pictures at a level beyond mere feature discrimination is by no means a trivial cognitive ability, and support of this is still weak in nonhuman species. Here, we report evidence of representational insight in pigeons. Responding to pictures of human body parts was compared in birds that had extensive pre-experience with live humans and in birds that had never seen any human heads. In a two-alternative forced-choice procedure the pigeons were trained to discriminate between pictures of either handless or headless humans and nonhumans. On test, the birds had to choose (i) between body parts they had already seen in training and the parts that had been missing, (ii) between previously seen parts and arbitrary skin patches, and (iii) between previously missing parts and skin patches. Only the pigeons that lacked experience with real heads and were trained with pictures of headless humans failed to show a significant preference for pictures of missing parts (i.e., heads) over arbitrary skin patches. This demonstrates the importance of individual experience with the real 3D-referents of pictures for classification of the latter and is thereby evidence of representational insight.  相似文献

Both in humans and non-human animals, it has been shown that individuals attend more to those they have previously interacted with and/or they are more closely associated with than to unfamiliar individuals. Whether this preference is mediated by mere social familiarity based on exposure or by the specific relationship between the two individuals, however, remains unclear. The domestic dog is an interesting subject in this line of research as it lives in the human environment and regularly interacts with numerous humans, yet it often has a particularly close relationship with its owner. Therefore, we investigated how long dogs (Canis familiaris) would attend to the actions of two familiar humans and one unfamiliar experimenter, while varying whether dogs had a close relationship with only one or both familiar humans. Our data provide evidence that social familiarity by itself cannot account for dogs’ increased attention towards their owners since they only attended more to those familiar humans with whom they also had a close relationship.  相似文献

In the 1920s, Otto Rank broadened the psychoanalytic treatment space by the prelingual relational and self-experience in the time before, during and after birth. This meant that early prelingual experiences at the level of emotions and sensations is always covertly present in the analytic situation. The special emphasis on the earliest relationship to the mother was perceived in the patriarchal society of the time as inadequate and unjustifiable. But the last decades provided perceptions in different therapeutic settings which seem to confirm the observations of Rank. Just as important are the findings of the empirical research in early brain development and in after effects of early traumatic stress which show the shaping role of early development in a completely new light. There are also new insights into particularities of early human development due to evolution, especially about the psychological consequences of the “physiological premature birth”. From this knowledge a new framework arises for the understanding of early development and for the assessment of the observations and conclusions of Rank. From a contemporary viewpoint this provides valuable contributions to the psychoanalytic research of the last decades into early after birth mother-child relationships. They bear the potential for a deeper understanding of the prelingual level of the psychoanalytic treatment situation.  相似文献

本文对黑格尔实践哲学的当代意义的众多层次进行了讨论。通过将黑格尔实践哲学与自由主义、社群主义以及其他相关社会理论进行比较分析,集中论述了三个命题,它们分别是(Ⅰ)黑格尔向我们展示了一种社会异化理论,或者更确切的说,是一种并不简单放弃"实践哲学"作为规范科学主张的"完全异化"理论;(Ⅱ)在一个包含基本法所有"生成层面"的统一的法的概念中,黑格尔区别了这一统一概念的不同层次——就如同她们最近被称之的那样。同时,将他们历史实现的问题主题化;(Ⅲ)黑格尔的法哲学包含一个政治的概念,这个概念对于现在追问国家任务的现实问题具有重大的批判意义。  相似文献
