Intentional action first

The paper motivates a novel research programme in the philosophy of action parallel to the ‘Knowledge First’ programme in epistemology. It is argued that much of the grounds for abandoning the quest for a reductive analysis of knowledge in favour of the Knowledge First alternative is mirrored in the case of intentional action, inviting the hypothesis that intentional action is also, like knowledge, metaphysically basic. The paper goes on to demonstrate the sort of explanatory contribution that intentional action can make once it is no longer taken to be a target for reductive analysis, in explaining other, non-intentional kinds of action and voluntariness.     

HIV voluntary counselling and testing among recently initiated and traditionally circumcised men in the Eastern Cape Province of South Africa

HIV voluntary counselling and testing (VCT) is a cornerstone of the national strategic plan for HIV/AIDS treatment, care and support in South Africa. However, research shows that the utilisation of VCT services is disappointingly low, particular among males. This article focuses on the factors associated with the intention to test for HIV-infection among recently initiated and traditionally circumcised men in the rural areas of Eastern Cape Province, South Africa. Individual face-to-face interviews were conducted among 1656 sexually active men. Logistic regression analyses were used to explore the association between intention to test for HIV and psychosocial factors. Overall, 35.1% of the participants reported ever having tested for HIV. Intention to test for HIV was positively associated with perceived probability of getting an STI, positive attitudes towards gender-based violence, received general teachings about being a responsible man and highest grade passed. These findings provide specific information that can be used in the development of a focused cultural sensitive STI/HIV prevention programme aimed to increase VCT uptake among sexually active young men, which can be integrated into initiation and health education practices.     

安乐死合法化的哲学辩护——以自由主义哲学为视角

安乐死问题一直都是一个争议性话题。从学理上,安乐死可以分为自愿安乐死和无意愿安乐死。自由主义的伦理学分为义务论和功利主义。以自由主义哲学观来审视两类安乐死合法化问题:自愿安乐死体现病人自由意志的选择,是人格尊严之自主性的结果;无意愿安乐死是由利益相关人代为选择,符合社会利益的最大化。通过严格立法来规范安乐死行为,也应成为我国法律的理性选择。     

汉字字形关联对错误记忆的影响

采用DRM范式,研究汉字字形关联对错误记忆的影响。实验以占汉字主体的形声字为材料。学习阶段使用了两类字表:在一半字表中,各字表内汉字及相应的关键诱饵具有相同形旁;另一半字表中,各字表内汉字及相应关键诱饵具有相同声旁。再认测试中,被试对两类关键诱饵均表现出了明显的错误记忆,并且其效应大小与字表汉字相似度成正比。这些结果说明,汉字的字形关联可以诱发错误记忆现象,并且这种错误记忆效应由汉字间字形相似度决定。     

A genetic variant (COMT) coding dopaminergic activity predicts personality traits in healthy elderly

Association studies between the NEO five factor personality inventory and COMT rs4680 have focused on young adults and the results have been inconsistent. However, personality and cortical changes with age may put older adults in a more sensitive range for detecting a relationship. The present study examined associations of COMT rs4680 and personality in older adults.Genetic association analyses were carried out between the NEO and the targeted COMT rs4680 in a large, well-characterized sample of healthy, cognitively normal older adults (N = 616, mean age = 69.26 years).Three significant associations were found: participants with GG genotype showed lower mean scores on Neuroticism (p = 0.039) and higher scores on Agreeableness (p = 0.020) and Conscientiousness (p = 0.006) than participants with AA or AG genotypes.These results suggest that older adults with higher COMT enzymatic activity (GG), therefore lower dopamine level, have lower Neuroticism scores, and higher Agreeableness and Conscientiousness scores. This is consistent with a recent model of phasic and tonic dopamine release suggesting that even though GG genotype is associated with lower tonic dopamine release, the phasic release of dopamine might be optimal for a more adaptive personality profile.     

The revelation of the negative side of a mental number line depends on list context: Evidence from a sign priming paradigm

Two parity judgement experiments examined how the activation of spatial-numerical associations of a single, centrally presented digit, reflected by the Spatial-Numerical Association Response Codes (SNARC) effect, is modulated by a preceding + (plus) or ? (minus) prime. The centrally presented prime prior to a digit presentation presumably triggers its positive or negative attributes. When the plus- and minus-primed trials were blocked, the left-small/right-large SNARC effects occurred regardless of prime type. When the plus- and minus-primed trials were randomly intermixed, this left-small/right-large SNARC effect occurred for plus-primed digits, but was reversed for minus-primed digits. The implications of this finding for context-dependent SNARC effects are discussed.     

Bidirectional associations of power and size in a priming task

Recent studies have shown that the size of a word's font affects people's judgements of its power. This result has been regarded as evidence for the association between power and size. It remains unclear, however, whether this association is bidirectional. The present study used a priming paradigm to determine whether processing power words was not only affected by processing size but also whether the reverse was true, consistent with metaphor representation being bidirectional. In Experiment 1, shapes in different sizes were used as priming materials, and power words were used as targets. In Experiment 2, to test the directionality of power and size, we tested two conditions using the exact same tasks but in reverse order: power words priming shapes and shapes priming power words. In Experiment 3, a significant priming effect was replicated when power words primed shapes in a lexical decision task rather than a powerful/powerless decision task. We found an interplay between power and size in all of the experiments. The bidirectional associations between power and size were in line with the strong version of Metaphoric Structuring, which claims that concrete concepts should influence abstract concepts and abstract domains should affect concrete domains. Thus, power is partially understood in terms of size, which demonstrates that abstract concepts are grounded in sensory motor processing.     

Alief and Explanation

This article critiques the much‐discussed notion of alief recently introduced by Tamar Gendler. The narrow goal is to show that the notion is explanatorily unnecessary; the broader goal is to demonstrate the importance of making explicit one's explanatory framework when offering a philosophical account of the mind. After introducing the concept of alief and the examples Gendler characterizes in terms of it, the article examines the explanatory framework within which appeal to such a concept can seem necessary. This framework, it argues, is a generalization of the belief‐desire account of action. Although Gendler introduces the notion of alief in an attempt to move beyond the belief‐desire account, it argues that she nevertheless works within a generalized version of its explanatory structure. Once the framework is made explicit, we find no explanatory need that requires introducing the notion of alief into our account of the mind.     

Enhancement of Creativity: Semantic Priming Through Naming Objects Loosens Functional Fixedness within Idea Generation

Functional fixedness is related to excessive focusing on a specific functional property of an object. We assumed that the naming of other objects which possess the same functional property to a lesser extent than a given object can reduce the excessive focusing on this functional property for this object. It can help to loosen functional fixedness and improve individual creative performance. We tested the effectiveness of this method with 302 participants aged between 17 and 22 (256 female and 46 male). The study consisted of two experiments with 110 and 192 participants, respectively. Prior to performing a creative activity (story writing in Experiment 1 and thinking up unusual uses of a given object in Experiment 2), participants from different groups were asked to name objects which possess the main functional property of the given object to the same extent, to a lesser extent, and to a greater extent, respectively. In both phases of the study, we found a significant effect on the extent of the target property possession on originality. Results showed that participants named objects with the lesser manifestation of a target property outperformed their counterparts from other groups.
