Psychological characteristics of aggressive drivers with and without intermittent explosive disorder
We compared two groups of aggressive drivers, those who met criteria for Intermittent Explosive Disorder (IED) (n=10) and comparable aggressive drivers who did not meet IED criteria (n=20), to a group of non-aggressive driving controls (n=20) on measures of psychological distress, anger, hostility, and Type A behavior as well as measures of aggressive driving and driving anger and their driving records. There were few differences between the aggressive drivers with IED and those without IED. The IED positive aggressive drivers endorsed more assaultiveness and resentment as well as more impatience and showed trends to have more hostility and angry temperament. When all aggressive drivers were compared to controls, differences emerged on anxiety, hostility, and anger as well as on measure specific to aggressive driving (competitiveness) and driving anger (at slow drivers and traffic obstructions). 相似文献

Figure-ground assignment is an important visual process; humans recognize, attend to, and act on figures, not backgrounds. There are many visual cues for figure-ground assignment. A new cue to figure-ground assignment, called lower region, is presented: Regions in the lower portion of a stimulus array appear more figurelike than regions in the upper portion of the display. This phenomenon was explored, and it was demonstrated that the lower-region preference is not influenced by contrast, eye movements, or voluntary spatial attention. It was found that the lower region is defined relative to the stimulus display, linking the lower-region preference to pictorial depth perception cues. The results are discussed in terms of the environmental regularities that this new figure-ground cue may reflect. 相似文献

This study investigated the relationship between dream emotion and dream character identification. Thirty-five subjects provided 320 dream reports and answers to questions on characters that appeared in their dreams. We found that emotions are almost always evoked by our dream characters and that they are often used as a basis for identifying them. We found that affection and joy were commonly associated with known characters and were used to identify them even when these emotional attributes were inconsistent with those of the waking state. These findings are consistent with the finding that the dorsolateral prefrontal cortex, associated with short-term memory, is less active in the dreaming compared to the wake brain, while the paleocortical and subcortical limbic areas are more active. The findings are also consistent with the suggestion that these limbic areas have minimal input from the dorsolateral prefrontal cortex in the dreaming brain. 相似文献

In their paper “Interactive Property Attribution in Concept Combination,” Estes and Glucksberg (2000) suggest an alternative to the alignment view of property interpretation— one based on salience and relevance of features. I suggest that alignment as well as feature salience and relevance are crucial to property interpretation. In making their claims, Estes and Glucksberg also assume that similarity has inverse effects on two important ways of interpreting combinations (i.e., property and relation interpretations). I show that this assumption does not generally hold and provide an alternative explanation for their results (one based on the plausibility of relation interpretations). 相似文献

In five experiments, we examined the time course of hemispheric differences in solution activation for insight-like problems. We propose that solving insight problems requires retrieval of unusual interpretations of problem elements, and that right-hemisphere (RH) coarse semantic coding is more likely than left-hemisphere (LH) fine semantic coding to maintain semantic activation of such interpretations. In four experiments, participants attempted word problems for 7 sec (Experiments 1A and 1B) or 2 sec (Experiments 2A and 2B), and 750 msec later responded to lateralized target words. After 7 sec of solving effort, Experiment 1A participants showed greater solution-related priming (i.e., they named solutions faster than unrelated words) for left visual field-RH (lvf-RH) targets than for right visual field-LH (rvf-LH) targets, and Experiment 1B participants made faster solution decisions on target words presented to the RH, as previously demonstrated following 15 sec of effort. After 2 sec of solving effort in Experiment 2A, women showed symmetric solution-related priming, although men showed a slight lvf-RH advantage in priming; and in Experiment 2B participants made equally quick solution decisions for targets presented to the LH and to the RH. In Experiment 3, participants viewed the problems for 1,250 msec then named lateralized target words; they showed symmetric solution-related priming. These experiments demonstrate solution activation initially in both hemispheres, but maintained solution activation only in the RH. 相似文献
