The present study focuses on the short-term effects of electronic entertainment media on memory and learning processes. It
compares the effects of violent versus non-violent computer game content in a condition of playing and in another condition
of watching the same game. The participants consisted of 83 female and 94 male adolescents with a mean age of 17.6 years.
The dependent variables are memory for previously learnt verbal and visual material, memory for media-related content and
physiological measures of stress (heart rate, cortisol, salivary alpha-amylase). Besides the group comparisons, potential
mediation effects and gender differences were examined. The results show that violent content leads to a poorer memory performance
for verbal material and to an increased heart rate. The heart rate, however, does not mediate the effect on memory performance.
Genders differ regarding their abilities to memorise verbal and visual material, with females showing a better performance
(independent of the experimental condition), and for memorising media-contents, where the males outperform females (also independent
of experimental condition). The study supports the assumption that violent and arousing media content has a negative short-term
effect on simultaneous information processing and learning and that there are gender-specific media effects. 相似文献

The Stroop Color-Word Test was used to measure selective attention in LD (N = 45) and nonLD (N = 50) children. Results indicated that LD children have a significant weakness in the process of selective attention when compared to nonLD children. On the Stroop, no significant sex differences were noted with nonLD children, although LD boys tended toward greater interference proneness in a trend that approached significance. Findings suggest that the Stroop is a parsimonious and effective screening measure in differentiating LD from nonLD children. 相似文献

A basic challenge of the Weinberg Report addressed the question of information overload. The Weinberg Panel was extremely
concerned with the proliferation of scientific literature and the specific issue of how to sift through reams of data to find
the “gems” of wisdom, or that which is truly new and useful. In the early 1960s when the report was being written, computers
were not part of the information access and retrieval infrastructure. Writing twenty-five years later, in 1988, Dr. Weinberg
recognized that the panel had not adequately taken into account the impact of the computer and the growth of the information
industry. Today we have a new world of microcomputers and networked information which is fundamentally shifting the paradigm
of scientific communication. We have new capabilities, including electronic publishing, visualization techniques, even virtual
reality. Without getting into a great debate about the definition of “grey literature,” the main characteristics have traditionally
been described as: rapid publication, wariable formats, no public peer review, and no commercial source of general availability.
With networked information and multi-media technology, the new world of grey literature is emerging with an interesting set
of new and revived challenges. This article looks at the most interesting characteristics, and based on them, presents the
thesis that in the 1990s we are facing a new generation of “grey literature”. 相似文献
