The aim of this paper is to offer an account of epistemic justification suitable for the context of theory pursuit, that is, for the context in which new scientific ideas, possibly incompatible with the already established theories, emerge and are pursued by scientists. We will frame our account paradigmatically on the basis of one of the influential systems of epistemic justification: Laurence Bonjour’s coherence theory of justification. The idea underlying our approach is to develop a set of criteria which indicate that the pursued system is promising of contributing to the epistemic goal of robustness of scientific knowledge and of developing into a candidate for acceptance. In order to realize this we will (a) adjust the scope of Bonjour’s standards—consistency, inferential density, and explanatory power, and (b) complement them by the requirement of a programmatic character. In this way we allow for the evaluation of the “potential coherence” of the given epistemic system. 相似文献

Do politically irrelevant events influence important policy opinions? Previous research on social welfare attitudes has emphasized the role of political factors such as economic self‐interest and ideology. Here, we demonstrate that attitudes to social welfare are also influenced by short‐term fluctuations in hunger. Using theories in evolutionary psychology, we predict that hungry individuals will be greedier and take more resources from others while also attempting to induce others to share by signaling cooperative intentions and expressing support for sharing, including evolutionarily novel forms of sharing such as social welfare. We test these predictions using self‐reported hunger data as well as comparisons of subjects who participated in relevant online studies before and after eating lunch. Across four studies collected in two different welfare regimes—the United Kingdom and Denmark—we consistently find that hungry individuals act in a greedier manner but describe themselves as more cooperative and express greater support for social welfare. 相似文献

Although gender ideologies and perceptions of equity in the division of household tasks have been associated with marital quality, there is limited understanding of the relationship between discrepancies (in husbands’ and wives’ subjective ideals and accounts of the division of labor) and relationship quality. We examined cognitive egalitarianism (beliefs about gender roles), behavioral egalitarianism (perceptions of the division of household tasks and management), and marital quality among 220 heterosexual, newlywed couples (N?=?440) living in east and central regions of the United States. We used multi-level modeling to examine associations between cognitive egalitarianism, behavioral egalitarianism, and marital quality with a specific focus on discrepancies in the reports of husbands and wives. As hypothesized, both husbands and wives had lower marital quality when their cognitive egalitarianism was discrepant from their partner, and such a discrepancy had a greater influence on wives’ reports of marital quality, especially for wives with higher cognitive egalitarianism. Although we expected similar results for the associations between behavioral egalitarianism and marital quality, we found that the strength of the association between wives’ behavioral egalitarianism and marital quality decreased as the discrepancy from their husbands’ behavioral egalitarianism increased. The association between cognitive egalitarianism and marital quality also increased as behavioral egalitarianism increased for wives but not for husbands. The results of this study illustrate the central role of spousal discrepancy in perceptions and enactment of household labor. 相似文献

Word-finding difficulties are usually assessed with picture-naming tests. In this article, we present the TDQ-60, a new test designed to assess acquired lexical access deficits, taking into account semantics and psycholinguistic variables. The article includes three studies. Study 1 describes the development phase of the TDQ-60. In study 2, healthy control participants and individuals with a diagnosis of the semantic variant of primary progressive aphasia were assessed to establish the convergent and discriminant validity of the TDQ-60. Finally, in Study 3, a group of 305 young and elderly French-speaking adults from Quebec were assessed in order to provide normative data. The results demonstrate that the TDQ-60 has good convergent validity and good discriminant validity. This study also provides normative data in which were considered the effect of age and education.The TDQ-60 is a new valid picture-naming test, controlled for psycholinguistic variables and designed to identify the influence of semantics on lexical access in spoken production. 相似文献

Despite increasing levels of per capita seafood consumption globally, consumption levels across the population vary with many consumers eating less than recommended weekly intakes. This study investigates the influence of childhood patterns of seafood consumption, consumer confidence in selecting and preparing seafood, adult eating habits, and lifestyle on seafood consumption. Partial least squares structural equation modelling analysis was conducted using a sample of 1,318 Australian adults. The results show that consuming seafood regularly in childhood and developing the confidence to select and prepare seafood as an adult contribute to the development of seafood eating habits. Subsequently, a habit of consuming seafood leads to a lifestyle involving regular consumption of seafood. The results indicate the need to develop and implement intervention strategies for encouraging childhood seafood consumption (“train the child”) and increasing adults' confidence in selecting and preparing seafood (“teach the adult”). Intervention strategies proposed include educational programmes targeted at both children and adults, combined with the development of seafood products that appeal to children and suit the changing lifestyle needs of today's 21st century consumers. 相似文献

This study examines the attachment quality and how this changed over time among infants who had cleft lip and palate (CLP), by conducting a prospective longitudinal study addressing the effects of this type of perinatal event on the parent–infant relationship and the emotional development of the infants. At 12 months of age, the Strange Situation Paradigm (SSP; M. Ainsworth, M.C. Blehar, E. Waters, & T. Wall, 1978) was administered to a sample of 38 CLP infants (born between 2003 and 2010) and 17 healthy controls. At 4 years of age, the Attachment Story Completion Task (ASCT; I. Bretherton, D. Ridgeway, & J. Cassidy, 1990) was administered to 32 individuals from the CLP sample and 14 from the control group. As reported in the literature, CLP infants display secure attachment behaviors as frequently as do control infants (55%). However, a more detailed analysis of the attachment scales revealed that CLP infants show more avoidance and less proximity seeking. In addition, a closer examination of the subcategories of attachment styles revealed that most CLP infants (71%) displayed distal attachment strategies such as the B1/B2 or A1/A2 subcategories. At 4 years old, CLP infants clearly displayed more deactivation and less security than did the control sample. Moreover, when detailing the evolution of attachment individually, almost 60% of the CLP children showing distal strategies at 12 months became deactivated or disorganized when they reached 4 years. Indeed, subtle differences in attachment behaviors at 12 months old—which can be considered marginally secure at that age—may reveal attachment vulnerabilities, which seem to be more apparent over the course of development. 相似文献

The aim of this study was to explore the extent to which persuasion principles are used in successful social engineering attacks. Seventy‐four scenarios were extracted from 4 books on social engineering (written by social engineers) and analysed. Each scenario was split into attack steps, containing single interactions between offender and target. For each attack step, persuasion principles were identified. The main findings are that (a) persuasion principles are often used in social engineering attacks, (b) authority (1 of the 6 persuasion principles) is used considerably more often than others, and (c) single‐principle attack steps occur more often than multiple‐principle ones. The social engineers identified in the scenarios more often used persuasion principles compared to other social influences. The scenario analysis illustrates how to exploit the human element in security. The findings support the view that security mechanisms should include not only technical but also social countermeasures. 相似文献

The ability to inhibit inappropriate responses and suppress irrelevant information is a core feature of executive control. In this study, we provide a detailed analysis of prepotent response inhibition and interference in patients with schizophrenia. To further test the role of genetic factors and subclinical schizophrenia‐like traits, we additionally studied clinically unaffected, first‐degree relatives of schizophrenia patients and assessed dimensions of schizotypy in both relatives and healthy controls. Inhibition and interference control were assessed using a battery comprising the antisaccade, Stroop, stop signal, go/no‐go, flanker, and Simon tasks. Schizophrenia patients differed from both relatives and controls in making more errors on the antisaccade task and having longer response times on the Stroop task, especially the incongruent condition. Patients also had general, that is, condition independent, increases in reaction times on the go/no‐go and flanker tasks and made more errors on the flanker and Simon tasks, suggesting general performance impairments independent of inhibitory demand. Relatives were characterized by hypometric antisaccade amplitude gain despite normal prosaccades, suggesting a selective deficit in non‐standard sensorimotor transformations. Schizotypy was correlated with inhibitory performance across a number of tasks in both relatives and controls. Generally, these effects were independent of verbal intelligence levels. Overall, the findings point to rather selective impairments of inhibitory control in the schizophrenia spectrum and confirm a previously observed deficit in antisaccade spatial accuracy as an endophenotype of schizophrenia. 相似文献

Serial position functions, with their characteristic primacy and recency effects, are ubiquitous in episodic memory tasks, and have also been observed in tasks tapping semantic memory. However, only one experiment, [Raanaas, R. K., & Magnussen, S. (2006a). Serial position effects in implicit memory. European Journal of Cognitive Psychology, 18, 398–414. doi:10.1080/09541440500162065], has demonstrated primacy and recency effects in implicit memory using an indirect memory test. In Experiment 1, we replicate this finding and in Experiment 2, we confirm a prediction that holds only if the serial position function observed in Experiment 1 was a “real” serial position function. These results confirm the presence of serial position functions in implicit memory and also support a general prediction of the relative distinctiveness principle that serial position functions should obtain whenever a set of items are ordered along a relevant dimension. 相似文献
