A dual-process model is suggested for the processing of words with emotional meaning in the cerebral hemispheres. While the
right hemisphere and valence hypotheses have long been used to explain the results of research on emotional stimulus processing, including nonverbal and
verbal stimuli, data on emotional word processing are mostly inconsistent with both hypotheses. Three complementary lines
of research data from behavioral, electrophysiological, and neuroimaging studies seem to suggest that both hemispheres have
access to the meanings of emotional words, although their time course of activation may be different. The left hemisphere
activates these words automatically early in processing, whereas the right hemisphere gains access to emotional words slowly
when attention is recruited by the meaning of these words in a controlled manner. This processing dichotomy probably corroborates
the complementary roles the two hemispheres play in data processing. 相似文献

Healthy aging is characterized by a number of changes on brain structure and function. Several neuroimaging studies have shown an age-related reduction in hemispheric asymmetry on various cognitive tasks, a phenomenon captured by Cabeza (2002) in the Hemispheric Asymmetry Reduction in Older Adults (HAROLD) model. Although this phenomenon is supported by a range of neuroimaging data on memory and inhibitory processes, there is little evidence concerning changes in hemispheric asymmetry for language processing, and particularly word retrieval, which is assessed with verbal fluency task (VFT). This study aimed to investigate the age-related changes in cerebral oxygenation in the prefrontal cortex for both letter and category VFT, varying the complexity of the criteria (i.e., degree of productivity) and using near-infrared spectroscopy (NIRS). Sixteen younger and 16 older adults participated in this study. For both VF conditions, participants were instructed to pronounce as many nouns as possible as a function of high-productivity (e.g., “animals” or “L”) or low-productivity (e.g., “flowers” or “V”) criteria. Behavioral data (i.e., accuracy responses) showed comparable performance in younger and older adults for both VF conditions. However, NIRS data showed more reduced activation (i.e., significantly reduced increase in [O2Hb] and reduced decrease in [HHb]) in older than younger adults for both VFT. In addition, a bilateral effect was found for both groups, suggesting that VFT requires both executive and language functions. The results are discussed in the context of the current theories of aging. 相似文献

In search for a European theological contribution to the debate on the new global context, this essay undertakes a theological‐aesthetic exploration of theological motifs in the current political imagination, in particular: the theme of the angel. After a problematisation of the theological reception of Benjamin's Messianic‐apocalyptic angel figure, I develop a critical position in the wake of von Balthasar. Von Balthasar's interpretations of Rilke and Bonaventure lead to two angelological paradigms, the monad and the crucified seraph, which occur in current political debates, as exemplified in recent essays of Zizek. 相似文献

This article aims to explore the attitudes and behaviors of persons with intellectual and developmental disabilities (IDD) related to their information privacy when using information technology (IT). Six persons with IDD were recruited to participate to a series of 3 semistructured focus groups. Data were analyzed following a hybrid thematic analysis approach. Only 2 participants reported using IT every day. However, they all perceived IT use benefits, such as an increased autonomy. Participants demonstrated awareness of privacy concerns, but not in situations involving the use of technology; their awareness is not transferred to the abstract context of IT use. Privacy breaches were revealed to be a major risk for persons with IDD, who did not seem to understand how their personal information was used. Most protection mechanisms and tools reported were those suggested and implemented by caregivers and close relatives who had a great influence on the participants’ attitudes and behaviors toward IT and privacy. Our findings suggest that when using IT, persons with IDD often experience the consequences of a trade-off between autonomy and privacy. Further research and action is needed to support persons with IDD to understand and balance the benefits of IT use and the inherent threats to information privacy. 相似文献

A pair of FORTRAN programs allows two individuals or groups to play prisoner’s dilemma and other two-party mixed-motive games on physically isolated terminals of a time-sharing computer. The programs provide a flexible tool for teaching and research through a series of programmable options for structuring and enhancing the playing environment of the game. Four participatory roles for students provide an opportunity for integrated exposure to the broader context of empirical research design and execution. 相似文献
