ABSTRACT This study investigates whether individual difference influences idiosyncratic experience of game playing. In particular, we examine the relationship between the game player's physical-aggressive personality and the aggressiveness of the player's game playing in violence-oriented video games. Screen video stream of 40 individual participants' game playing was captured and content analyzed. Participants' physical aggression was measured before the game play. The results suggest that people with more physical-aggressive personality engage in a more aggressive style of playing, after controlling the differences of gender and previous gaming experience. Implications of these findings and direction for future studies are discussed. 相似文献

Scalar implicature has served as a test case for exploring the relations between semantic and pragmatic processes during language comprehension. Most studies have used reaction time methods and the results have been variable. In these studies, we use the visual-world paradigm to investigate implicature. We recorded participants’ eye movements during commands like “Point to the girl that has some of the socks” in the presence of a display in which one girl had two of four socks and another had three of three soccer balls. These utterances contained an initial period of ambiguity in which the semantics of some was compatible with both characters. This ambiguity could be immediately resolved by a pragmatic implicature which would restrict some to a proper subset. Instead in Experiments 1 and 2, we found that participants were substantially delayed, suggesting a lag between semantic and pragmatic processing. In Experiment 3, we examined interpretations of some when competitors were inconsistent with the semantics (girl with socks vs. girl with no socks). We found quick resolution of the target, suggesting that previous delays were specifically linked to pragmatic analysis. 相似文献

Familiar and recognizable stimuli enjoy an advantage of predominance during binocular rivalry, and this advantage is usually attributed to their enhanced processing during the dominant phase. However, do familiar and recognizable stimuli have an advantage in breaking suppression? Test images were gradually introduced to one eye to compete against a standard high-contrast dynamic noise pattern presented to the other eye. Results showed that an upright face took less time than an upside-down face to gain dominance against the identical suppression noise. Results also showed that for Chinese readers, Chinese characters were faster to gain dominance than Hebrew words, whereas for Hebrew readers, the reverse was true. These results suggest that familiar and recognizable information, even when suppressed and invisible, is processed differently from unfamiliar information. Apparently, high-level information about visual form does contribute to the strength of a stimulus during its suppressed phase. 相似文献

重庆市直辖以来卫生资源配置公平性研究 总被引:3,自引:0,他引:3
采用基尼系数方法从人口和地理分布两个方面定量分析重庆市卫生资源配置的公平性。重庆市主要卫生资源中,护士的基尼系数最高;重庆市的三个经济区域中,都市发达经济圈的基尼系数最高;资源按地理配置的公平性要差于按人口配置。重庆市护理人员严重不足且分布不公平,资源地理配置的公平性有待改善。 相似文献
