Seventy-nine 3-year olds and their mothers participated in a laboratory-based task to assess maternal hostility. Mothers also reported their behavioral regulation of their child. Seven years later, functional magnetic resonance imaging data were acquired while viewing emotional faces and completing a reward processing task. Maternal hostility predicted more negative amygdala connectivity during exposure to sad relative to neutral faces with frontal and parietal regions as well as more negative left ventral striatal connectivity during monetary gain relative to loss feedback with the right posterior orbital frontal cortex and right inferior frontal gyrus. In contrast, maternal regulation predicted enhanced cingulo-frontal connectivity during monetary gain relative to loss feedback. Results suggest parenting is associated with alterations in emotion and reward processing circuitry 7–8 years later. 相似文献

The application of lasers for the removal of superficial deposits from historic stained glass is a comparatively new field of scientific interest. Experimental studies concerning the behaviour of glass substrates and the corresponding superficial deposits towards different laser wavelengths were carried out. The experiments were performed using wavelengths of λ = 193 nm (ArF-Excimer), 308 nm (XeCl-Excimer), 355 nm (Nd:YAG third harmonic) and 1 064 nm (Nd:YAG fundamental) in comparison to λ = 248 nm (KrF-Excimer). This comparison is due to the fact that the present knowledge is based on the 248 nm wavelength. Specially prepared model glass samples representing the original fragments and samples of organic polymers (formerly used as a protective material for historic stained glasses) were used to study the effects of laser radiation and were subsequently characterised by optical microscopy. 相似文献

A two-stage analysis examined visuals in news related to governmental surveillance, finding that just as surveillance has shifted from visual evidence to dataveillance, journalism is shifting its notion of visual evidence from photojournalism to journalistic data representations. First, a card sort analysis of news visuals was conducted on two news sites before and after Edward Snowden's document leak in June 2013. The news images remained relatively consistent, relying heavily on accessible official and stock photography sources. Second, a review of The Guardian's contemporaneous “NSA Files: Decoded” multimedia package found personalized, data-rich visual storytelling techniques. Between the two approaches is a vast difference in how surveillance is represented and made accessible, with implications for the visual coverage of other challenging news topics. 相似文献

The definitions of developmental dyslexia andtemporal processing are discussed and severalconstruals of what a temporal processingdeficit might entail are illustrated. Then,using a framework developed by Farmer & Klein(1995), the proposal that a temporal processingdeficit (in vision, audition, or both) might bethe root cause of some proportion of cases ofdevelopmental dyslexia is introduced andvarious research strategies for testing thisproposal are identified. The symposium paperswhich address this general question using arange of these strategies are then criticallyreviewed. It is noted that whereas reading isa recent artifact not yet subject to any directselection pressure, its normal performancerequires the use of, and connections between,the highly evolved modules for visual patternrecognition and language. Within vision andlanguage redundant coding, which permitsperformance in the face of injuries anddegraded input, also makes it difficult todetect subtle deficits (whether temporal, ornot) unless precise tests are used. Yet suchdeficits may degrade performance on tasks (suchas reading) which require the non-copiousconnections between vision and language. Theefficacy of this pathway, I suggest, ismeasured by performance on the rapidautomatized naming (RAN) test. 相似文献

The common practice of using discussion groups during case-based learning makes the role of discussion important in these
learning environments. However, little empirical research has been done to investigate the influence of discussion on performance
and motivation in case-based learning. The purpose of this article is to present the results of a study conducted to examine
the role of discussion groups in a case-based environment. College students completed two cases either individually or in
small discussion groups. Measures included two case analyses, an attitude survey, time on task, and document analysis. Results
revealed significant performance and time differences between instructional methods on the first case, but not on the second
case. In addition, results indicated significant differences in student attitudes between treatments. Overall, participants
who worked in groups liked their method significantly better than those who worked alone, felt they learned more working in
a group than they would have working alone, and expressed a preference for working in a group if they had to do the class
over again. Implications for implementing case-based learning and future research are discussed.
