Classical informal reasoning "fallacies," for example, begging the question or arguing from ignorance, while ubiquitous in everyday argumentation, have been subject to little systematic investigation in cognitive psychology. In this article it is argued that these "fallacies" provide a rich taxonomy of argument forms that can be differentially strong, dependent on their content. A Bayesian theory of content-dependent argument strength is presented. Possible psychological mechanisms are identified. Experiments are presented investigating whether people's judgments of the strength of 3 fallacies--the argumentum ad ignorantiam, the circular argument or petitio principii, and the slippery slope argument--are affected by the factors a Bayesian account predicts. This research suggests that Bayesian accounts of reasoning can be extended to the more general human activity of argumentation. 相似文献
Findings across a wide body of research suggest that media targeted at young audiences often portray characters according to stereotypical gender roles. Childhood is a particularly sensitive time in gender identity development, and logic from social cognitive theory suggests that repeatedly observing these stereotypes can have a lasting influence on young audiences’ worldview. Building on previous research investigating gender role displays in film content, and with the expectation that content creators use movie posters to convey a one-shot summary of films to audiences, we conducted a content analysis on the gendered power depictions of the main characters in movie posters of 152 popular U.S. animated children’s feature films produced over the last 80 years. Findings revealed that main characters were more likely to be male and that males were portrayed as more powerful. These results add to a growing, yet substantial, body of research illustrating the prevalence of stereotypical gender role portrayals across virtually every popular medium with which children come into contact. We discuss our results’ implications for potential short-term and long-term effects of exposure to films’ gender role stereotypes on young viewers’ real-life gender role expectations.
In the present research we investigated how action influences affective evaluation. In three experiments, participants conducted a sequence of go/no-go tasks, then evaluated the pleasantness of a novel shape. The results of Experiments 1 and 2 show that participants evaluated the shapes that appeared in the go trials more positively than the shapes that appeared in the no-go trials. In Experiment 3, the go/no-go task was conducted without the to-be-evaluated shapes present in the display. The results show that the shape stimuli following the go trials were evaluated more positively than the shape stimuli following the no-go trials, even when the shapes were not directly associated with the go/no-go task. Based on the present study, we suggest that activating or inhibiting a motoric action may play a critical role in modifying one's affective evaluation. Additionally, the present results suggest that effortful and non-default responses can negatively modulate affective evaluation by taxing an individual's cognitive load. Furthermore, we argue that individuals can potentially control their affective states through behavioral activation and inhibition. 相似文献
Face identification is more accurate when people collaborate in social dyads than when they work alone (Dowsett & Burton, 2015, Br. J. Psychol., 106, 433). Identification accuracy is also increased when the responses of two people are averaged for each item to create a ‘non-social’ dyad (White, Burton, Kemp, & Jenkins, 2013, Appl. Cogn. Psychol., 27, 769; White et al., 2015, Proc. R. Soc. B Biol. Sci., 282, 20151292). Does social collaboration add to the benefits of response averaging for face identification? We compared individuals, social dyads, and non-social dyads on an unfamiliar face identity-matching test. We also simulated non-social collaborations for larger groups of people. Individuals and social dyads judged whether face image pairs depicted the same- or different identities, responding on a 5-point certainty scale. Non-social dyads were constructed by averaging the responses of paired individuals. Both social and non-social dyads were more accurate than individuals. There was no advantage for social over non-social dyads. For larger non-social groups, performance peaked at near perfection with a crowd size of eight participants. We tested three computational models of social collaboration and found that social dyad performance was predicted by the decision of the more accurate partner. We conclude that social interaction does not bolster accuracy for unfamiliar face identity matching in dyads beyond what can be achieved by averaging judgements. 相似文献
The diallel cross genetic design was employed to determine the pattern of inheritance of male-male agonistic behavior in laboratory mice. The results indicated strong strain differences in agonistic behaviors and strain ranks that replicated previous findings. The genetic analysis showed the presence of additive and nondirectional dominance effects on the behaviors measured. This pattern has been characterized as indicating the action of stabilizing selection and indicates that the trait has not been under directional selection. 相似文献
The German plural system has recently become a focal point for conflicting theories of language, both linguistic and cognitive. Marcus et al. (1995) highlight the German plural as support for the dual-route account of inflectional morphology first proposed by Pinker and colleagues (Pinker & Prince, 1988). On the dual-route account, inflectional morphology is universally subserved by a symbolic rule route which deals with regular inflection and an associative memory component which deals with irregular inflection. This contrasts with single-route connectionist systems. We seek to counter supposed evidence for the dual-route account through large-scale simulations as well as through experimental data. We argue that, in its current form, the dual-route account is incapable of generating experimental data provided by Marcus et al. (1995) as support. Finally, we provide direct quantitative comparisons between single-route and dual-route models of German plural inflection and find single-route performance superior on these tests. 相似文献
The paper deals with experience gained in the town of Leipzig in the course of the implementation of the regionalized organisation of psychiatric care. The idea behind the organisational structure is that of a complete psychiatric system of treatment, covering hospitalised, partially hospitalised, and out-patient treatment, supported by ancillary services, to provide continued care. The organisational structure has proved effective for basic psychiatric care in a large town. 相似文献
