Abstract We performed numerical simulations to demonstrate localization phenomena of Bose–Fermi mixture systems on incommensurate optical lattices by changing Bose–Bose and Bose–Fermi interactions. Visibility patterns of the bosons were measured to observe bosonic coherence in various selections of the interaction parameters. We found that the coherence was enhanced with repulsive Bose–Fermi interactions. It was also enhanced with attractive Bose–Fermi interactions but only in certain conditions. The enhancement by repulsive interactions and that by attractive interactions occurred with different mechanisms. 相似文献

Japanese bilinguals retrieved autobiographical memories in response to 20 English and 20 Japanese cue words. US monolinguals were cued with 40 English words. All participants reported one earliest memory. Japanese bilinguals retrieved more memories and earlier memories when cued with Japanese words. They also retrieved more memories when the cue language matched either the language of memory encoding or the language of first thought. Although English cues elicited equivalent numbers of English and Japanese memories in the more fluent speakers of English, Japanese words elicited significantly larger numbers of Japanese memories in all Japanese-English bilinguals. The average age of cued autobiographical memories was significantly earlier for US than for Japanese students but age of the earliest memory did not differ. 相似文献

The purpose of this study was to explore the experience of foreign-born international medical graduates (IMGs) in the USA. Few studies describe IMG experiences in attaining medical licensure in the USA at each step of the process. Furthermore, little is known about IMGs who choose not to become a licensed physician or were unsuccessful in doing so. In this study, 20 foreign-born IMGs, 16 practicing IMGs and 4 non-licensed physician IMGs, participated in a 1-h semi-structured face-to-face interview between September 2013 and April 2014. Participants were from North America (Canada), Latin America, South Asia, East Asia, Europe, the Middle East, or Sub-Saharan Africa. Interviews were transcribed. Two of the authors conducted initial analysis of each interview separately. Four primary themes emerged based on the data analysis: (1) barriers to physician careers include the immigration process, years since graduating from medical school, language and culture, and cost and time; (2) positive factors to support physician careers include networking and research experience; (3) factors that positively or negatively affect IMGs seeking physician careers such as the education system in a home country and family; and (4) non-physician careers. In order to develop multiple pathways to utilize IMGs in the US healthcare system, future research examining the following areas is necessary: (1) support systems for IMGs who are taking the US Medical Licensing Exam (USMLE) or applying for a residency position and (2) the experience of IMGs who are not certified physicians in the USA. 相似文献

People's attributional phenomenology is likely to be characterized by effortful situational correction. Drawing on this phenomenology and on people's desire to view themselves more favorably than others, the authors hypothesized that people expect others to engage in less situational correction than themselves and to make more extreme dispositional attributions for constrained actors' behavior. In 2 studies, people expected their peers to make more extreme dispositional inferences than they did themselves for a situationally constrained actor's behavior. People's expectation that they engage in more situational correction than their peers was diminished among Japanese participants, who have less desire to view themselves as superior to their peers (Study 3), and among participants who were led to view dispositional attributions more favorably than situational attributions (Study 4). 相似文献

Previous research has demonstrated distinct neural correlates for maintenance of abstract, relational versus concrete, sensory information in working memory (WM). Storage of spatial relations in WM results in suppression of posterior sensory regions, which suggests that sensory information is task-irrelevant when relational representations are maintained in WM. However, the neural mechanisms by which abstract representations are derived from sensory information remain unclear. Here, using electroencephalography, we investigated the role of alpha oscillations in deriving spatial relations from a sensory stimulus and maintaining them in WM. Participants encoded two locations into WM, then after an initial maintenance period, a cue indicated whether to convert the spatial information to another sensory representation or to a relational representation. Results revealed that alpha power increased over posterior electrodes when sensory information was converted to a relational representation, but not when the information was converted to another sensory representation. Further, alpha phase synchrony between posterior and frontal regions increased for relational compared to sensory trials during the maintenance period. These results demonstrate that maintaining spatial relations and locations in WM rely on distinct neural oscillatory patterns. 相似文献

We tested the hypothesis that the level of reduced laterality in language is correlated with the degrees of schizotypal personality in healthy individuals and with their performance in the remote-associate task (RAT). A total of 53 healthy participants completed a schizotypal personality measure of the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE; a questionnaire measuring the level of psychotic proneness), a consonant–vowel–consonant (CVC; requiring the identification of letter trigrams presented tachistoscopically in the left/right visual fields or both), measuring reduced language laterality and a remote-associate task (RAT; requiring to report a word, weakly associated with three cue words). Analysis revealed correlations between CVC and O-LIFE, as well as between CVC and RAT performance. The results suggest that reduced language lateralisation (reduced hemispheric integration) may play a role in schizophrenic language disorganization, as reflected in highly schizotypal individuals, and that hemispheric integration plays a role in the remote-associate task. 相似文献

AbstractWe investigated whether bilateral lower-limb control and leg dominance affect force control ability in 15 healthy young adults (9 males and 6 females, age =26.8?±?4.1 years). Participants performed isometric ankle dorsiflexion force control tasks, matching a visual target (10% of maximal effort) as quickly and precisely as possible in ballistic and tonic tasks. Performance was evaluated using force error, force steadiness, amount of muscle activity of the tibialis anterior, and response time characteristics. Results showed no significant effects of leg dominance during both ballistic and tonic tasks, while bilateral condition resulted in significantly larger error, less force steadiness, compared to unilateral condition, and only during the tonic task. Consequently, bilateral control, specifically in tasks utilizing feedback control (i.e., tonic task) might affect force control ability, possibly because of the interhemispheric inhibition to meet bilateral task complexity and integrate afferent bilateral sensory information from both right and left legs. 相似文献

Within-individual variability in self-concepts and everyday personality states and affects was investigated in two experience sampling studies using density distribution and situation-behavior approaches. In all seven cultures sampled, within-individual variability was substantial and self-concept and personality state variability exhibited moderate convergence. Variability in personality and affect states was moderately predicted by perceived need satisfaction in the situations. The density distribution and situation-behavior approaches were moderately convergent in identifying the most variable individuals, but the pattern of cultural differences differed in the two methods. Contrary to cultural psychology perspectives, cultural differences in within-individual variability did not consistently correspond to cultural differences in individualism–collectivism, dialecticism, or tightness. 相似文献
