The lateralization of emotion processing is currently debated and may be further explored by examining facial expression recognition (FER) impairments in temporal lobe epilepsy (TLE). Furthermore, there is also debate in the literature whether FER deficits in individuals with TLE are more pronounced in the right than in the left hemisphere. Individuals with TLE were tested with an FER task designed to be more sensitive than those classically used to shed light on this issue. A total of 25 right- and 32 left-TLE patients, candidates for surgery, along with controls, underwent an FER task composed of stimuli shown not only at full-blown intensities (100 %), but also morphed to lower-intensity display levels (35 %, 50 %, and 75 %). The results showed that, as compared to controls, right-TLE patients showed deficits in the recognition of all emotional categories. Furthermore, when considering valence, right-TLE patients were impaired only in negative emotion recognition, but no deficits for positive emotions were highlighted in left-TLE patients. Finally, only the right-TLE patients’ impairment was found to be related to the age of epilepsy onset. Our work demonstrates that the FER deficits in TLE span multiple emotional categories and show manifestations dependent on the laterality of the epileptic focus. Taken together, our findings provide the strongest evidence for the right-hemisphere model, but they also partially support the valence model. We suggest that current models are not exhaustive at explaining emotional-processing cerebral control, and further that multistep models should be developed. 相似文献

Previous research reported conflicting results concerning the influence of depression on cognitive task performance. Whereas some studies reported that depression enhances performance, other studies reported negative or null effects. These discrepant findings appear to result from task variation, as well as the severity and treatment status of participant depression. To better understand these moderating factors, we study the performance of individuals-in a complex sequential decision task similar to the secretary problem-who are nondepressed, depressed, and recovering from a major depressive episode. We find that depressed individuals perform better than do nondepressed individuals. Formal modeling of participants' decision strategies suggested that acutely depressed participants had higher thresholds for accepting options and made better choices than either healthy participants or those recovering from depression. 相似文献

Based on terror management theory, previous research has shown that terrorism threat increases prejudice against Muslims and is mediated by death‐related thoughts. Because this effect was found on a correlational level, it remains unclear whether terrorism threat increases prejudice against Muslims because of enhanced death‐related thoughts or the opposite: terrorism threat increases death‐related thoughts because of stronger prejudice against Muslims. To disentangle this shortcoming, we varied death‐related thoughts by systematically manipulating the belief in literal immortality. Using two studies, we found that participants exposed to terrorism pictures (vs. controls) had increased prejudice against both Muslims (Study 1) and immigrants (Study 2) when they were led to believe that literal immortality does not exist but not when they were led to believe that it does exist. Mediation analysis indicated that this effect was mediated by death‐related thoughts. This provides further evidence that terrorism threat increases prejudice because of death‐related thoughts. 相似文献

Previous research has found that performing norm-violating behaviors based on a nonconsciously-activated goal elicits negative affect (Oettingen, Grant, Smith, Skinner, & Gollwitzer, 2006). In the present research we explored whether this negative affect is eliminated when an earlier conscious goal with congruent behavioral effects can be used to explain the norm-violating behavior. Our findings suggest that applicable conscious goals are indeed used to interpret nonconsciously-activated goal striving (Study 1), and that this interpretation occurs reflexively rather than reflectively (Study 2), with implications for interpersonal behavior (Study 3). The role of social norms, applicable conscious goals, and negative affect in the interpretation of nonconscious goal pursuit is discussed. 相似文献

In this paper, I distinguish between two varieties of actualism—hardcore actualism and softcore actualism—and I critically
discuss Ross Cameron’s recent arguments for preferring a softcore actualist account of the truthmakers for modal truths over
hardcore actualist ones. In the process, I offer some arguments for preferring the hardcore actualist account of modal truthmakers
over the softcore actualist one. 相似文献

Suppose we want to take seriously the neoverificationist idea that an intuitionistic theory of meaning can be generalized
in such a way as to be applicable not only to mathematical but also to empirical sentences. The paper explores some consequences
of this attitude and takes some steps towards the realization of this program. The general idea is to develop a meaning theory,
and consequently a formal semantics, based on the idea that knowing the meaning of a sentence is tantamount to having a criterion
for establishing what is a justification for it. Section 1 motivates a requirement of epistemic transparency imposed onto
justifications conceived as mental states. In Section 2, the formal notion of justification for an atomic formula is defined,
in terms of the notion of cognitive state. In Section 3, the definition is extended to logically complex formulas. In Section
4, the notion of truth-ground is introduced and is used to give a definition of logical validity. 相似文献

Expert video game players often outperform non-players on measures of basic attention and performance. Such differences might result from exposure to video games or they might reflect other group differences between those people who do or do not play video games. Recent research has suggested a causal relationship between playing action video games and improvements in a variety of visual and attentional skills (e.g., [Green, C. S., & Bavelier, D. (2003). Action video game modifies visual selective attention. Nature, 423, 534-537]). The current research sought to replicate and extend these results by examining both expert/non-gamer differences and the effects of video game playing on tasks tapping a wider range of cognitive abilities, including attention, memory, and executive control. Non-gamers played 20+ h of an action video game, a puzzle game, or a real-time strategy game. Expert gamers and non-gamers differed on a number of basic cognitive skills: experts could track objects moving at greater speeds, better detected changes to objects stored in visual short-term memory, switched more quickly from one task to another, and mentally rotated objects more efficiently. Strikingly, extensive video game practice did not substantially enhance performance for non-gamers on most cognitive tasks, although they did improve somewhat in mental rotation performance. Our results suggest that at least some differences between video game experts and non-gamers in basic cognitive performance result either from far more extensive video game experience or from pre-existing group differences in abilities that result in a self-selection effect. 相似文献

When asking about the worldview and ethics behind such stories as The Chronicles of Narnia, readers should try to understand C.S. Lewis's work in light of the Tao or moral Natural Law. Even though our modern culture affirms a relativism in values, Lewis affirms a non-relativist universal ground for moral judgment. Lewis's theological work, Mere Christianity, provides the clue for this interpretation. Despite the apparent negativity or violence in even some of the most memorable scenes in the Chronicles, the underlying moral is hopeful and positive, reflecting a 'mere Christian' worldview. 相似文献

Classical theories of crowd behaviour view crowd conflict as deriving from the pathology of the crowd itself. Recent developments in crowd psychology as the elaborated social identity model (ESIM) conceptualize crowd behaviour as a dynamic intergroup process between demonstrators and police. The present study assessed exposure to crowd conflict, adherence to classical views of crowd behaviour, public order policing methods and attributions of responsibility for crowd conflict among 352 Italian police officers. Results showed that exposure to crowd conflict was related to adherence to classical views of crowd, which, in turn, was related to ‘bad practices’ of public order policing and to system‐justificatory attributions. Overall, these results offer support and extend the police perspective within the ESIM model. Practical implications for public order policing strategies and training are also discussed.
