Letter identification is a critical front end of the reading process. In general, conceptualizations of the identification process have emphasized arbitrary sets of distinctive features. However, a richer view of letter processing incorporates principles from the field of type design, including an emphasis on uniformities across letters within a font. The importance of uniformities is supported by a small body of research indicating that consistency of font increases letter identification efficiency. We review design concepts and the relevant literature, with the goal of stimulating further thinking about letter processing during reading. 相似文献

The linkages between individual characteristics of political leaders and their usage of historical analogy during foreign policy decision-making episodes were examined. The individual characteristics studied were conceptual complexity and policy expertise, while usage of analogy was studied in terms of the sophistication and source of historical comparisons. The great majority of the analogies used by low-complexity individuals were nonsophisticated, whereas high-complexity individuals consistently used more sophisticated analogies. Low-complexity individuals drew analogies solely from their own generational and cultural context, while high-complexity leaders drew their analogies from a wider range of sources. More expert leaders drew from their personal experiences to a marginally greater degree than less expert individuals but, interestingly, both types of individual relied on generally available rather than personally experienced events for their analogies. The value added of the approach is to demonstrate that different types of leaders use history differently during political decision making. 相似文献

In the Vietnam and Iraq conflicts, British Prime Ministers were asked to contribute forces to an American‐led war that was deeply unpopular in the United Kingdom. This presented Harold Wilson and Tony Blair with conflicting incentives and constraints: to support their senior ally or to make policy based upon domestic considerations. Why did Harold Wilson decline to commit British forces while Tony Blair agreed to do so? With situational factors generating conflicting predictions, I argue that investigation of individual‐level variables is necessary. In particular, I suggest that leaders vary systematically in their willingness to subordinate the concerns of constituents to strategic imperatives, and that introducing the leadership style categories of “constraint challenger” and “constraint respecter” can make more determinate the linkage between domestic politics and strategic concerns. 相似文献

In five experiments, participants made speeded target/nontarget classification responses to singly presented auditory stimuli. Stimuli were defined via vocal identity and location in Experiments 1 and 2 and frequency and location in the remaining experiments. Performance was examined in two conditions inspired by visual search: In the feature condition, responses were based on the detection of unique stimulus features; in the conjunction condition, unique combinations of features were critical. Experiment 1 showed a conjunction benefit, since classifications were faster in the conjunction condition than in the feature condition. Potential confounds were eliminated in Experiments 2 and 3, which resulted in the observation of conjunction costs. In Experiments 4 and 5, we examined, respectively, whether the cost could be explained in terms of differences in interstimulus similarity and target template complexity across the main conditions. Both accounts were refuted. It seems that when the identification of particular feature combinations is necessary, conjunction processing in audition becomes an effortful process. 相似文献

Recent evidence suggests that fibromyalgia, a chronic widespread pain condition and related syndromes (chronic fatigue syndrome, irritable bowel syndrome, etc.) may share heritable pathophysiologic features. We review the recent literature on genetic and familial factors found to participate in the pathogenesis of these syndromes, specifically fibromyalgia, including evidence suggesting that serotonin- and dopamine-related genes may play a role in the pathogenesis of these illnesses. The importance of environmental factors triggering these conditions in predisposed individuals is also discussed. 相似文献

64 normal adult controls (53 men, 11 women; M age 45.2 yr.) in a study of an estuary-associated syndrome were administered the MMPI-2-180 and the Neuroticism scale from the NEO-Personality Inventory. Pearson product-moment correlations between MMPI-2 scales and the Neuroticism scale were similar to those reviously reported using the full-length MMPI. Correlations between MMPI-2 scales, D, Pt, Sc, and Si, and NEO-PI Neuroticism (range .44 to .52) suggest that many psychiatric conditions are associated with psychological distress of the type individuals high in trait neuroticism are prone to experience. 相似文献

A face valid set of 22 highly intercorrelated items was developed to investigate the attitudes towards science of 793 Grade 12 pupils (age ranging from 17 to 24+ years) in Lebowa, South Africa. Analysis indicated the attitudes of these students towards science were neutral and hardly enthusiastic, which would encompass negative, neutral, and positive attitudes. 相似文献
