If belief has an aim by being a (quasi) intentional activity, then it ought to be the case that the aim of belief can be weighed against other aims one might have. However, this is not so with the putative truth aim of belief: from the first‐person perspective, one can only be motivated by truth considerations in deliberation over what to believe (exclusivity). From this perspective then, the aim cannot be weighed. This problem is captured by David Owens's Exclusivity Objection to belief having an aim (2003). Conor McHugh (2012; 2013) has responded to this problem by denying the phenomenon of exclusivity and replacing it with something weaker: demandingness. If deliberation over what to believe is characterised by demandingness and not exclusivity, this allows for the requisite weighing of the truth aim. I argue against such a move by suggesting that where non‐evidential considerations play a role in affecting what we believe, these considerations merely change the standards required for believing in a particular context, they do not provide non‐evidential reasons for forming or withholding belief, which are considered as such from the deliberative perspective. Exclusivity thus remains, and so too does Owens's objection. 相似文献

研究目的:通过针对"相关线索-习惯性用药行为"联结的消退训练,降低渴求感,建立新联结,达到减弱或消退成瘾记忆的目的。探索以"动作消退动作"的方法对成瘾动作记忆进行消退的效果和可行性。方法:采用途径偏向矫正方法对28名男性药物成瘾者开展为期4周的训练。训练前后,分别测试渴求感、生理指标、途径偏向效应和Addiction-stroop task的干扰效应量,比较训练前后的指标变化,了解训练的效果。结果:训练组和对照组在训练前后的途径偏向效应没有显著的组间和交互效应,但训练组在训练前后途径偏向效应发生变化,趋向显著性,t=1.26,p=0.071。渴求感在训练组显著降低:t=1.38,p=0.05。Stroop的反应时间呈训练时间主效应:t=4.18,p=0.04。结论:途径偏向矫正消退训练可以改善成瘾者的途径偏向效应和渴求感状况,预示着通过身体动作建立"相关线索-拒绝用药行为"联结替代原有的"相关线索-自动化用药行为"联结,降低渴求感,减弱或消退成瘾记忆是有可能的。未来的研究需要采用更为精确的影像手段进行测试,验证基于动作认知的成瘾记忆消退训练的有效性。 相似文献

Research on motivational climates within athletics has focused on mastery and ego achievement approaches, yielding different psychological consequences (Smith, Smoll, &; Cumming, 2007). Further, the motivational climate may interact with athletes' trait characteristics, such as grit, resulting in different outcomes. Grit may alter athletes' experience of the motivational climate by helping them remain oriented to their long-term quest in sport (Duckworth, Peterson, Matthews, &; Kelly, 2007). However, to date, the impact of these motivational climates and potential moderating factors on athlete performance remains in question, as the research utilizing objective measures of athletic performance is limited (Harwood, Keegan, Smith, &; Raine, 2015). We used a motivational research paradigm (e.g., Mueller &; Dweck, 1998) to examine the effects of mastery- or ego-involving feedback on 71 high school adolescent soccer players' (Mage = 15.81) performance on a kicking task. Then we explored the potential moderating effects of grit on the relationship between motivational feedback and the athletes' performance, desire to persist, and choice of task difficulty on a soccer task. Athletes performed significantly better receiving mastery- as opposed to ego-involving feedback. Further, grit was a significant moderator of the feedback-shooting performance relationship, accounting for 3.9% of variance. Simple slopes analysis revealed a significant effect for low (B = 13.32, SEb = 4.44, p =.004, t = 2.99), but not high (B = 2.11, SEb = 4.31, p =.63, t = 0.49), grit on task performance. These results suggest that the feedback athletes receive matters, especially for those low in grit. 相似文献

The authors examined the perception of college students from Greek organizations on the effectiveness of an alcohol intervention program that included gender‐specific programming. Significant reductions in risky alcohol use were found in men who attended and evaluated the program as helpful. 相似文献

快速启动范式(Sereno & Rayner, 1992)是一种基于呈现随眼动变化技术而设计的眼动范式,主要用于研究中央凹视野内字词识别的瞬时启动,通过精确控制启动条件和启动时窗,以考察词汇通达过程中词汇水平(如,词频、词长等)、亚词汇水平(如,语音、语义、字形等)信息的加工时序。本文从基本原理、设计基础、应用领域、注意事项等方面对快速启动范式进行了较为深入的解读和介绍,并结合已有的研究成果,指出了该范式在汉语阅读中的应用价值。 相似文献

研究不同反应重复量对反应抑制后效应的影响。采用停止信号范式,让被试完成不同反应重复量的反应抑制任务。结果显示,总的来说反应重复量因素和重复类型因素的主效应都显著;信号抑制条件下重复一次后比重复三次后无信号试次反应时要显著地长,但都与总的无信号试次反应时没有显著差异;信号反应条件下重复三次后与重复一次后无信号试次反应时没有显著差异,但都比总的无信号试次反应时显著地长。结果表明,不同反应重复量反应抑制后效应在信号抑制条件下既有认知控制调整也有自动化记忆提取,在信号反应条件下仅存在认知控制的执行加工。 相似文献

Differences in the distribution of arginine vasopressin (AVP) and a subtype of AVP receptors, the V1a receptor, may explain dissimilarities in social behavior of monogamous and non‐monogamous rodents. Intracerebroventricular infusions of AVP and a V1a antagonist were used in sexually naive males of two mouse species, the monogamous and highly aggressive California mouse (Peromyscus californicus) and the non‐monogamous and less aggressive white‐footed mouse (P. leucopus), to begin testing the interaction between the social system of a species and the effects of AVP on aggression. Two testing conditions, the resident‐intruder aggression test (R‐I) and the neutral arena aggression test, were used because they may differ in function and underlying biological mechanisms. In the R‐I test, administration of the antagonist lengthened attack latencies in California mice. In contrast, blocking V1a receptors did not alter attack latencies in the R‐I test in white‐footed mice or in the neutral arena aggression test in both species. AVP also did not alter aggression in either species in either behavioral test. Overall, these results suggest that AVP may be more likely to be associated with offensive aggression as measured in the R‐I test than with neutral arena aggression and that the effects of AVP manipulations may differ between monogamous and non‐monogamous rodents.
