Additive theories of rationality, as I use the term, are theories that hold that an account of our capacity to reflect on perceptually‐given reasons for belief and desire‐based reasons for action can begin with an account of what it is to perceive and desire, in terms that do not presuppose any connection to the capacity to reflect on reasons, and then can add an account of the capacity for rational reflection, conceived as an independent capacity to ‘monitor’ and ‘regulate’ our believing‐on‐the‐basis‐of‐perception and our acting‐on‐the‐basis‐of‐desire. I show that a number of recent discussions of human rationality are committed to an additive approach, and I raise two difficulties for this approach, each analogous to a classic problem for Cartesian dualism. The interaction problem concerns how capacities conceived as intrinsically independent of the power of reason can interact with this power in what is intuitively the right way. The unity problem concerns how an additive theorist can explain a rational subject's entitlement to conceive of the animal whose perceptual and desiderative life he or she oversees as ‘I’ rather than ‘it’. I argue that these difficulties motivate a general skepticism about the additive approach, and I sketch an alternative, ‘transformative’ framework in which to think about the cognitive and practical capacities of a rational animal. 相似文献

Action video game playing has been experimentally linked to a number of perceptual and cognitive improvements. These benefits are captured through a wide range of psychometric tasks and have led to the proposition that action video game experience may promote the ability to extract statistical evidence from sensory stimuli. Such an advantage could arise from a number of possible mechanisms: improvements in visual sensitivity, enhancements in the capacity or duration for which information is retained in visual memory, or higher-level strategic use of information for decision making. The present study measured the capacity and time course of visual sensory memory using a partial report performance task as a means to distinguish between these three possible mechanisms. Sensitivity measures and parameter estimates that describe sensory memory capacity and the rate of memory decay were compared between individuals who reported high evels and low levels of action video game experience. Our results revealed a uniform increase in partial report accuracy at all stimulus-to-cue delays for action video game players but no difference in the rate or time course of the memory decay. The present findings suggest that action video game playing may be related to enhancements in the initial sensitivity to visual stimuli, but not to a greater retention of information in iconic memory buffers. 相似文献

Even with the lack of consensus on the nature of an argument, the thesis that explanations and arguments are distinct is near orthodoxy in well-known critical thinking texts and in the more advanced argumentation literature. In this paper, I reconstruct two rationales for distinguishing arguments from explanations. According to one, arguments and explanations are essentially different things because they have different structures. According to the other, while some explanations and arguments may have the same structure, they are different things because explanations are used for different purposes than arguments. I argue that both rationales fail to motivate a distinction between arguments and explanations. Since these are the only rationales for distinguishing arguments from explanations that I am prepared to take seriously, I don’t see why we should exclude explanations from being arguments. 相似文献

Recent scholarship traces the roots of southern violence to the Scots-Irish, who brought a relatively violent “cracker culture” with them to the United States in the eighteenth century. The tolerance for violence inherent in cracker culture was believed to be transmitted throughout the south to other whites and was maintained, in part, through evangelical Christian doctrine. Moreover, Thomas Sowell (2005) recently argued that some southern blacks were also influenced by “cracker culture,” leading to the emergence of a “black redneck” phenomenon influencing homicide among blacks. Using county-level data circa 2000, this study empirically evaluates the merit of the cracker culture/black redneck thesis. Negative binomial regression analyses for a full sample of counties suggest that a measure of southern cracker/black redneck culture is an important factor affecting contemporary rates of argument homicide among both whites and blacks. When counties are divided into south and non-south sub-samples, the results are also consistent: a cracker/black redneck culture effect is evident for both racial groups in the south, and is also apparent outside of the southern region. We interpret these latter findings as possible support for the thesis that southern cracker/black redneck culture has been transported through migration to non-southern localities. 相似文献

The present study examined the efficacy of a brief, written exposure therapy (WET) for posttraumatic stress disorder (PTSD). Participants were 46 adults with a current primary diagnosis of motor vehicle accident-related PTSD. Participants were randomly assigned to either WET or a waitlist (WL) condition. Independent assessments took place at baseline and 6-, 18-, and 30-weeks post baseline (WL condition not assessed at 30 weeks). Participants assigned to WET showed significant reductions in PTSD symptom severity at 6- and 18-week post-baseline, relative to WL participants, with large between-group effect sizes. In addition, significantly fewer WET participants met diagnostic criteria for PTSD at both the 6- and 18-week post-baseline assessments, relative to WL participants. Treatment gains were maintained for the WET participants at the 30-week post baseline assessment. Notably, only 9% of participants dropped out of WET and the WET participants reported a high degree of satisfaction with the treatment. These findings suggest that a brief, written exposure treatment may efficaciously treat PTSD. Future research should examine whether WET is efficacious with other PTSD samples, as well as compare the efficacy of WET with that of evidence-based treatments for PTSD. 相似文献

Presentation of bilateral redundant visual stimuli produces faster reaction times (RT) than presentation of a single unilateral stimulus; an effect known as the redundant target effect (RTE; Miller, 1982), and is a means of testing interhemispheric visuomotor integration (Ouimet, 2009). RTEs that exceed expectations, based on Miller's race model of inequality (RMI), are referred to as "enhanced RTEs" and imply neural coactivation. Paradoxically, enhanced RTEs are observed in cases of corpus callosum disruption. The Hemispheric Coactivation Hypothesis accounts for this paradox by positing that bihemispheric processing occurs to both unilateral and bilateral stimuli in the normal brain, but occurs only with bilateral stimuli in the disconnected brain. Neuroimaging has revealed decreases in the microstructural integrity of the corpus callosum with age (Ota et al., 2006), but research investigating the bilateral RTE in healthy older individuals is lacking. The present study investigated the bilateral RTE in healthy younger and healthy older adults using simple RT and choice RT tasks. Our prediction that older individuals would show significantly larger RTEs than younger individuals was found to be true for both tasks. Tests of the RMI produced little evidence for coactivation. The crossed-uncrossed difference, generally used as a means of testing visuomotor interhemispheric transfer, was also investigated, but no age effects were found. The observation of greater RTE in age is congruent with the Hemispheric Coactivation hypothesis (Miller, 2004) in which callosal disconnection is associated with increased RTE. 相似文献

Introduction A great volume of popular literature produced by Islamists strives to demonstrate the universal validity of the Islamic political principles and their applicability in any time and place. Although there is an agreement on certain characteristics of a government in a Muslim society, the debate reflects quite varied interpretations and some essential theoretical differences. The controversy stems largely from the conditions that scholars live in. Regarding the revived interest in creating a state based on Islamic political and moral guidelines, it is possible to encounter various interpretations and different standpoints. For instance, one point of view asserts that ‘the undemocratic nature of Islamic political ideology, popularised in the present times by fundamentalist ideologues, commends it to regimes which have no popular support and need to find some measure of legitimacy’ (Tibi, 1998). With the failure of man-made ideologies and withdrawal of imperialist western powers, according to another standpoint, the inhabitants of the Third World countries were led to revitalise their own sociopolitical values and institute their own political systems. In the case of the Islamic world, the idea of a state based on Islamic political principles, envisaged in the latter perspective, is ’the rekindling of the typical Islamic political ethos‘; in that Islam unifies the spiritual and social realms, it is therefore impossible to divorce politics from religion (Sulaiman, 1987). There is a wide range of contributions and critiques on the issue of Islamic principles guiding the constitutional aspects of a state, particularly since the Iranian Revolution in 1979. The interest in this matter has increased since the terrorist attacks in the USA on 11 September 2001, coinciding with a rising interest in such issues as Islamic social order and so-called Islamic terrorism. Nevertheless, most of these writings are popular and sensational; analytical studies are few. This article aims to fill the gap in scholarly inquiry into such an important matter by exploring the political ideas of major contemporary Muslim thinkers, and by identifying some essential characteristics for a state based on Islamic political principles in the light of the views of these scholars. 相似文献

Religious Experience Reconsidered offers an “attribution theory of religion” which builds out from Emile Durkheim’s intuition that the sacred is just some aspect of the world that has been set apart. Despite this theoretical pedigree, however, the book violates the central Durkheimian insight when it goes on to ask whether some things are more likely to be set apart than others. I argue that this impulse is motivated by an unfortunate metaphysical desire to determine if some things really are special. Throwing my hat in with Durkheim, I maintain that the academic study of religion should rest content with analyzing the contested politics of “deeming” something special. 相似文献

Gray’s (1970) reinforcement sensitivity theory (RST) was recently updated (Gray & McNaughton, 2000), but the changes have not received extensive empirical validation. The study tests three novel predictions of the revised RST. First, the behavioral activation system (BAS) is expected to be sensitive to both conditioned and unconditioned incentives. Second, the behavioral inhibition system (BIS) is expected to be sensitive to conflicting incentives such as between unconditioned and conditioned stimuli, and not to avoidance responses or aversive stimuli alone. Third, during approach-avoidance conflicts only, BAS is expected to moderate BIS responses to conflict such that individuals with high BAS show the strongest effect of BIS. In order to test these hypotheses, we developed a novel incentive task that crosses approach/avoidance conditioned responses to appetitive/aversive unconditioned stimuli. Conflict between unconditioned and conditioned stimuli occurred on the approach-aversive and avoid-appetitive trials. Results confirm the predictions and provide support for the revised RST. 相似文献
