People living with HIV can experience posttraumatic stress disorder (PTSD). Complex relationships exist between HIV, PTSD and cognitive impairments. This cross-sectional study compared three cognitive impairments (false memory, attentional bias, deficits in future thinking) among people living with HIV with and without PTSD in Iran. People living with HIV with PTSD (n = 20) and without PTSD (n = 20) completed measures of psychological symptomatology, dot-probe task, Deese Roediger McDermott paradigm and future thinking task at Razavi Khorasan Health Center. The PTSD group, when compared to the non-PTSD group, recognised a significantly greater number of false memories (p < .001; η2 = .58), had an attentional bias toward threat-related words (p < .001; η2 = .35) and imagined fewer specific future events (p < .001; η2 = .31). People living with HIV with PTSD may have difficulties with false memory, attentional biases, and generating future events. Since psychological treatments are limited in Iran, this research highlighted some potential cognitive targets for people living with HIV.  相似文献

Feminist thought, despite the importance of its work, has not resolved the phenomenon of women's subordination in the care and education of children, and in society as a whole. Meanwhile, we are witnessing a gradual but continuous process of disconnection between women's bodies and subjectivity, and the conception, pregnancy and birth of children, due to developments in reproductive techniques. Considering this paradoxical tension, the author proposes to return to the very place where this subordination and anticipated rupture occur, to consider whether mothers could find there both the means to reclaim their childbirth experiences and potential levers for emancipation and rebirth, on both a personal and societal level. To this end, she describes, from the point of view of a singular woman, and from an emancipatory perspective, the phenomenological and psychoanalytical itinerary of childbirth by which this woman, in becoming a mother, is born to herself by giving birth to her child. By co-constituting the universal meaning of childbirth and becoming a philosophical mother, this singular woman operates a real paradigm shift in our representations of the mother and the metaphysical structure of the sexes.  相似文献

The Air Force SPACECAST 2020 study identified and prioritized some future space systems and technologies required in the next century. This paper presents the results of research on the SPACECAST 2020 value model. The model determines and prioritizes future space systems’ utility towards controlling and exploiting space. This research identifies the assumptions and simplifications in the additive utility function and assesses modifications. The research shows that mutual utility independence of the mission areas is a reasonable assumption. Mutual utility independence allows the use of the multiplicative and multilinear utility functions. Also, the SPACECAST 2020 scoring functions used the same scoring scale and only measured the utility of future capabilities. This study makes modifications to the SPACECAST 2020 measure-of-merit scoring functions. It replaces most of these functions with either a concave, convex, linear or ‘S’ scoring function, which have expanded capability ranges to include both current and future capabilities. The modified scoring functions and alternative utility functions do not alter the SPACECAST 2020 results but do improve the credibility and future usefulness of the model. This study shows that the initial assumption of using an additive utility function is also valid. © 1997 John Wiley & Sons, Ltd.  相似文献

A brief account is given of the author's life as a physicist and then a priest. The twin foundations of the author's theological endeavors have been a respect for traditional Christian thinking, though not exempting it from revision where this is needed, and a style of argument termed bottom-up thinking, which seeks to proceed from experience to understanding. The diversity of the world faith traditions is perceived as a major source of perplexity. A revised and modest natural theology and the issue of divine action have been at the top of a science and theology agenda. A defense is sketched in realist terms of the metaphysical strategy of using an ontological interpretation of the unpredictabilities of chaos theory to support a notion of top-down causality through active information. The success of Christian theology as a resource of total explanation depends on a credible account of eschatological hope. Reference is made to practical experience of ethics in the public square.  相似文献

We have limited knowledge as to whether the phenomenological differences between episodic memories, counterfactuals, and future projections show the same pattern across age groups and diverse samples. Here we compared the characteristics of these mental events, reported by younger and older participants in a Turkish (Study 1) and in an American sample (Study 2). In both studies, memories contained more sensory-perceptual-spatial details, were easier to bring to mind, and more specific. Future projections were the most positive, whereas counterfactuals were the least emotionally intense. In Study 1, older participants rated the events more positively and experienced them with more perceptual detail, whereas younger participants reported the future to be more voluntarily rehearsed, important, and central. These age differences did not replicate in Study 2. Overall, phenomenological differences between the events are robust and replicate across diverse samples. However, age differences are more sensitive to cultural or individual differences.  相似文献

The scientific approach to the study of creative problem-solving has shifted from using classic insight problems (e.g., the Nine-dots problem), toward sets of problems that have more robust psychometric properties, such as the Remote Associate Test (RAT). Because it is homogeneous, compact, quickly solvable, and easy to score, the RAT has been used more frequently in recent creativity studies. We applied the Item Response Theory (IRT) to develop an Italian version of this task. The final 51-item test was reliable (α = .89) and provided information over a wide range of ability levels, as revealed by the IRT analysis. The RAT correlated with five measures of creative performance: The Raven's Standard Progressive Matrices (SPM), three classic insight problems, a set of anagrams purposefully developed, the fluency and flexibility scores of the Alternative Uses Task (AUT), and the Creative Achievements Questionnaire (CAQ). The new measure provided is meant to encourage the study of creativity and problem-solving in the Italian language.  相似文献

Creativity is linked to broad scope of attention, a state or trait that allocates attentional resources over a wide range of perceptual stimuli. According to the attentional priming hypothesis, a mechanism underlying the creativity–attention link is that broad perceptual attention scope primes broad conceptual attention scope—the activation of a wide range of memory contents—which therefore facilitates creative ideation. This study aimed to test the hypothesis in three experiments using three manipulations and two creativity tasks. Experiment 1 used the Navon letter task to prime attention to global patterns or local details of composite stimuli and measured creativity via the task to generate alternative uses of daily objects. Experiment 2 modified a cue-size procedure in which participants repeatedly attended to large or small visual cues before a target stimulus appeared. Experiment 3 devised a manipulation that required participants to view and visualize images associated with broad or narrow attention and adopted the alternative uses task and the task to invent alien creatures. Across the experiments, although the results were in the predicted direction, they were non-significant. This study found no evidence that broadness of perceptual attention affects creativity.  相似文献

Researchers often use divergent thinking tasks to assess creative potential and find a positive inter-individual relation between fluency and originality. But are there different within-person patterns of originality and fluency? Study 1: undergraduates completed an alternate uses task and the NEO-FFI. Three profiles emerged: (1) low originality and fluency; (2) above average originality, moderate fluency; and (3) average originality, high fluency. Study 2: high school students completed a divergent thinking task and 10 facets of the IPIP NEO-PI. Four profiles emerged: (1) average originality, moderate fluency; (2) above average originality, high fluency; (3) low originality and fluency; and (4) high originality, low fluency. Profile differences in personality and maximum originality, and implications of these findings are discussed.  相似文献
