On the basis of an existential analysis (Daseinanalyse), the authors consider the suicide, at age 42, of Cesare Pavese, one of the most important Italian poets and writers of the post-World War II period. It is found that in his poems, his novels, and particularly his letters and diary the idea of suicide was present in his consciousness since adolescence; year by year it is possible to follow the development of his ideas and fantasies about suicide. Incapable of establishing authentic communication with others, Pavese narrowed his existential horizon to the point of being less and less capable of living in the world and projecting himself into the future. From these considerations it is concluded that Pavese's acute feeling of incapacity caused him to have lasting experiences of failure that brought him to view suicide as the only way to free himself from his own torment. 相似文献
Fifty years after the first humans stepped on the Moon, space faring nations have entered a new era of space exploration. NASA’s reference mission to Mars is expected to comprise 1100 days. Deep space exploratory class missions could even span decades. They will be the most challenging and dangerous expeditions in the history of human spaceflight and will expose crew members to unprecedented health and performance risks. The development of adverse cognitive or behavioral conditions and psychiatric disorders during those missions is considered a critical and unmitigated risk factor. Here, we argue that spatial cognition, i.e., the ability to encode representations about self-to-object relations and integrate this information into a spatial map of the environment, and their neural bases will be highly vulnerable during those expeditions. Empirical evidence from animal studies shows that social isolation, immobilization, and altered gravity can have profound effects on brain plasticity associated with spatial navigation. We provide examples from historic spaceflight missions, spaceflight analogs, and extreme environments suggesting that spatial cognition and its neural circuitry could be impaired during long-duration spaceflight, and identify recommendations and future steps to mitigate these risks.
ABSTRACTLanguage switching typically leads to language switch costs. Previous studies demonstrated that production-based language switching often results in reduced costs when the languages are assigned to distinct modalities (i.e. bimodal language switching) compared to switching within a modality (i.e. unimodal switching). In Experiment 1–3, we compared unimodal to bimodal switching in language perception. In Experiment 4, unimodal switching was compared to bivocal switching (i.e. languages were assigned to different voices). Experiment 1–3 revealed significantly higher switch costs for bimodal than for unimodal switching, indicating fundamental differences to language production studies. While bimodal switching leads to no (additional) costs but – under specific conditions – even to advantage in production, it increases switch costs in language perception. Moreover, Experiment 4 indicates that this is more a modality-specific rather than a general perception-based effect. Different voices instead of different modalities evoked no similar increase in switch costs. 相似文献
The present research addresses the question of how romantically involved individuals are able to shield their ongoing romantic relationship from the temptation of attractive alternative partners. Specifically, two studies examined, and supported, the prediction that self-regulation promotes romantically involved individuals’ tendency to derogate attractive others as potential partners. Heterosexual participants responded to pictures of attractive and unattractive opposite-sex others by indicating their interest in these others as potential partners. In both studies the possibility for self-regulation exertion was manipulated (by means of self-regulation depletion in Study 1, and time-pressure in Study 2). When self-regulatory resources were relatively high, romantically involved participants exhibited less interest in attractive opposite-sex others than non-involved participants. However, when self-regulatory resources were low, interest in attractive opposite-sex others did not differ between romantically involved and non-involved participants. 相似文献
When observing ostracism, individuals can either side with the target or the sources of ostracism. Here we demonstrate that side-taking depends on whether the target previously acted in adherence to or in violation of perceived social norms. In four studies, a target behaved either norm-consistently or violated a social norm, and was subsequently either excluded by the sources or was not. Next, participants could sanction the behavior of the observed persons by refraining to assign money (Studies 1 and 2), or by subtracting money from a bonus (Studies 3 and 4). Observers assigned less money to the sources when these excluded a norm-consistent target. However, when the target had violated a social norm before, participants assigned less money to the target instead. These results have far-reaching implications because the (in)actions of neutral individuals can legitimize the sources’ behavior, or help a target under attack. 相似文献
