The article addresses the problem of how semantic information can be upgraded to knowledge. The introductory section explains
the technical terminology and the relevant background. Section 2 argues that, for semantic information to be upgraded to knowledge,
it is necessary and sufficient to be embedded in a network of questions and answers that correctly accounts for it. Section
3 shows that an information flow network of type A fulfils such a requirement, by warranting that the erotetic deficit, characterising the target semantic information t by default, is correctly satisfied by the information flow of correct answers provided by an informational source s. Section 4 illustrates some of the major advantages of such a Network Theory of Account (NTA) and clears the ground of a
few potential difficulties. Section 5 clarifies why NTA and an informational analysis of knowledge, according to which knowledge
is accounted semantic information, is not subject to Gettier-type counterexamples. A concluding section briefly summarises
the results obtained. 相似文献

The typical mortality salience manipulation asks participants to reflect on two questions, one about the emotions associated with the thought of death and the other about what happens after one dies. In five experiments, we separated these two questions and gave participants either one or a control question. In Experiment 1, participants' responses to the afterlife question were coded as being informed more by cultural knowledge and values compared with responses to the emotion question. Experiments 2 and 3 demonstrated that participants responding to the afterlife question showed greater stereotype usage compared with those responding to the emotion or a control question. In Experiment 4, results illustrate that the afterlife and emotion question differ on various coding dimensions related to self‐focus, emotion, and culturally related death words, but not death‐related words. In addition, participants who responded to the afterlife question demonstrated greater cultural worldview defense by setting a higher bail for an alleged prostitute compared with those who answered the emotion or a control question. In Experiment 5, participants responding to the emotion question demonstrated a greater preference for personally endorsed values compared with those who responded to the emotion or a control question. These results suggest that the two questions used in the common mortality salience manipulation produce different results when separated. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Stuttering impacts on the child in a variety of ways, notably in terms of communicative impairment and psychosocial impact. In addition, the stuttering disorder has a holistic impact, affecting those with whom the child who stutters lives. Within the family constellation, the closest person to the individual who stutters is often their sibling. This study investigated the experiences of fluent siblings of children who stutter to examine the impact that stuttering may have on their lives. A mixed methods research design incorporated qualitative semi-structured interviews and quantitative questionnaires. The results of the qualitative investigation revealed four aspects of children's lives that were affected by having a sibling who stuttered: the relationship between siblings, the impact on the fluent sibling, the impact on the parent relationship with both children, and the impact on the sibling's relationship with others. Findings revealed that siblings of children who stutter exhibited strongly negative emotions, and differing levels of responsibility associated with their involvement in the actual stuttering management programme. Furthermore, for the fluent sibling, secondary to having a brother or sister who stuttered, communication with and attention from their parents was variable. The results of the quantitative component of the study revealed children who stutter and their siblings demonstrated significantly greater closeness, and concurrently, increased conflict and status disparity than did the control fluent sibling dyads. The parents of the experimental sibling dyads also demonstrated significantly greater partiality towards a child, namely the child who stuttered, than did the parents of the control sibling dyads. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) identify the themes associated with having a sibling who stutters; (2) identify how the quality of the sibling relationship differs between sibling dyads that do and do not consist of a sibling who stutters; and (3) discuss the clinical implications of the results with regards to working with children who stutter and their families. 相似文献

In A New Form of Agent-Based Virtue Ethics, Daniel Doviak develops a novel agent-based theory of right action that treats the rightness (or deontic status) of an action
as a matter of the action’s net intrinsic virtue value (net-IVV)—that is, its balance of virtue over vice. This view is designed
to accommodate three basic tenets of commonsense morality: (i) the maxim that “ought” implies “can,” (ii) the idea that a
person can do the right thing for the wrong reason, and (iii) the idea that a virtuous person can have “mixed motives.” In
this paper, I argue that Doviak’s account makes an important contribution to agent-based virtue ethics, but it needs to be
supplemented with a consequentialist account of the efficacy of well-motivated actions—that is, it should be transformed into a mixed (motives-consequences) account, while retaining
its net-IVV calculus. This is because I believe that there are right-making properties external to an agent’s psychology which it is important to take into account, especially when an agent’s actions negatively affect
other people. To incorporate this intuition, I add to Doviak’s net-IVV calculus a scale for outcomes. The result is a mixed view which accommodates tenets (ii) and (iii) above, but allows for (i) to fail in certain cases.
I argue that, rather than being a defect, this allowance is an asset because our intuitions about ought-implies-can break
down in cases where an agent is grossly misguided, and our theory should track these intuitions. 相似文献

This study investigated whether young and older adults vary in their beliefs about the impact of various mitigating factors on age-related memory decline. Eighty young (ages 18-23) and 80 older (ages 60-82) participants reported their beliefs about their own memory abilities and the strategies that they use in their everyday lives to attempt to control their memory. Participants also reported their beliefs about memory change with age for hypothetical target individuals who were described as using (or not using) various means to mitigate memory decline. There were no age differences in personal beliefs about control over current or future memory ability. However, the two age groups differed in the types of strategies they used in their everyday life to control their memory. Young adults were more likely to use internal memory strategies, whereas older adults were more likely to focus on cognitive exercise and maintaining physical health as ways to optimize their memory ability. There were no age differences in rated memory change across the life span in hypothetical individuals. Both young and older adults perceived strategies related to improving physical and cognitive health as effective means of mitigating memory loss with age, whereas internal memory strategies were perceived as less effective means for controlling age-related memory decline. 相似文献

Misattributions people make about their own reaction to ambiguous stimuli can be used to measure personality self‐concepts implicitly. On the basis of a semantic misattribution priming paradigm [semantic misattribution procedure (SMP)], we assessed the implicit personality self‐concept related to three dimensions included in the Big‐Five model: conscientiousness, neuroticism, and extraversion. Across three studies (N1 = 98, N2 = 140, and N3 = 135), the SMP was robustly related, in the expected direction, to individual differences in self‐reported personality questionnaires and managed to predict both self‐reported and objectively measured behaviours. The main advantage of SMP over classical explicit measures of personality is its higher resistance to social desirability tendencies, although its psychometric properties are somewhat lower than those pertaining to explicit measures of personality. Finally, comparisons of our results with studies that used other implicit measures of personality self‐concept indicate that the SMP has higher criterion validity.

Self-efficacy is a key construct underlying healthy functioning and emotional well-being. Perceptions of uncontrollability, unpredictability, and low self-efficacy are consistently associated with negative mental health outcomes, such as post-traumatic stress disorder (PTSD). To test the causal relation between perceived coping self-efficacy and stress responses we employed a trauma film paradigm in which college students (N=33) viewed a graphic film of the aftermath of a motor vehicle accident following a high (HSE) or low self-efficacy (LSE) induction. Participants were tested for intrusions, distress, and memory recall for the film over the following 24 hours. LSE participants recalled more central details than HSE participants. Further, HSE participants reported fewer negative intrusions immediately following the film and at 24 hours. These findings suggest that strategies that increase perceived coping self-efficacy may reduce intrusive recollections of an aversive event, and also reduce the attentional bias associated with remembering aversive stimuli. 相似文献

Current models of autobiographical memory suggest that self-identity guides autobiographical memory retrieval. Further, the capacity to recall the past and imagine one's self in the future (mental time travel) can influence social problem solving. We examined whether manipulating self-identity, through an induction task in which students were led to believe they possessed high or low self-efficacy, impacted episodic specificity and content of retrieved and imagined events, as well as social problem solving. Compared to individuals in the low self efficacy group, individuals in the high self efficacy group generated past and future events with greater (a) specificity, (b) positive words, and (c) self-efficacious statements, and also performed better on social problem solving indices. A lack of episodic detail for future events predicted poorer performance on social problem solving tasks. Strategies that increase perceived self-efficacy may help individuals to selectively construct a past and future that aids in negotiating social problems. 相似文献
