We examined the role of stress exposure on gender differences in hostile (emotional and behavioral) reactions within the context of a laboratory paradigm. Aggressive behavior was indexed via the intensity (overt) and the duration (covert) of putative shocks delivered to a confederate. Half of the participants were exposed to a chronic stressor (high stress) and half were not (low stress). Participants' emotional responses were measured via self-report mood ratings before and after the experiment. Men displayed higher aggression in both stress conditions, which corresponded to their ratings of state hostility. On the other hand, women in high stress delivered lower intensity shocks, and this decreased overt aggression was positively correlated with sadness ratings. However, women did not decrease their levels of shock duration (covert aggression) under high stress and showed equivalent shock duration compared with men in high stress. These findings are discussed in terms of differential overt manifestations of distress between men and women. 相似文献

Do familiarity and expectations change perception? Drivers’ glances and response to changes 总被引:1,自引:1,他引:0

The present study shows that repeated exposure to a road environment changes eye movement behaviour. In addition, repeated exposure may result in inadequate responses to unexpected changes in the road environment. Participants drove a low-cost simulator while their eye movements were recorded. With repeated exposure participants’ glances at traffic signs along the route were shorter while having a better recollection of the traffic signs along the route. At the last drive, the priority situation at an intersection was changed (a priority road was changed into a yield situation). Even though drivers glanced at the sign that indicated the new priority situation, they did not sufficiently process the information to show an adequate response. Only two out of 12 drivers showed any response, being a response only after crossing the priority road markings. The current finding that unexpected but relevant information may be missed by drivers is relevant for other monitoring tasks. 相似文献

An inverse akratic act is one who believes X, all things considered, is the correct act, and yet performs ~X, where ~X is
the correct act. A famous example of such a person is Huck Finn. He believes that he is wrong in helping Jim, and yet continues
to do so. In this paper I investigate Huck’s nature to see why he performs such acts contrary to his beliefs. In doing so,
I explore the nature of empathy and show how powerful Huck’s empathic feelings are. Drawing from Martin L. Hoffman, I show
the relationship between empathy and a principle of justice. This relationship leads to Huck acting virtuously, as Rosalind
Hursthouse maintains.

采用Wearden和Ferrara(1993)的经典方法, 分别考察了1s以下(350 ms~650 ms)和1s以上(1000 ms ~ 2000 ms)不同类型(空、实时距)和通道(视、听)时距的短时保持效应。实验1发现, 不同刺激通道条件下, 1s以下时距的短时保持都呈现出主观缩短, 其中视觉条件比听觉条件明显; 实验2表明, 1s以上时距在不同刺激通道条件下都呈现出主观变长, 其中听觉条件比视觉条件明显。分析表明, 主观缩短趋势可能是由主观缩短效应和正的顺序误差效应共同作用所致, 而主观变长趋势是由主观变长效应和负的顺序误差效应造成的。 相似文献

The effect of differential time-out (TO) durations (15, 30, 45, 60, and 90 minutes) on assaultive behavior for 13 psychiatrically hospitalized children and adolescents was analyzed. For the total sample, no statistically significant difference in assault frequencies was evident. Also evident was the effect of time-out duration on time taken to become settled: the longer the time-out given, the longer the time needed to become calm. 相似文献

The study examined whether there are two independent cognitive factors affecting duration estimation. In two experiments, we manipulated simultaneously and independently two variables, namely, the level of attention to the lapse of time and the quantity of perceived changes, and examined their effects on duration estimation under a prospective paradigm. The duration was estimated to be longer when subjects attended to the lapse of time than when they attended to tasks during the target interval (Experiments 1 and 2). The characteristics of external stimuli irrelevant to the tasks, namely, the rate of presentation of sounds (Experiment 1) and the velocity of moving dots (Experiment 2), affected duration estimation, even though the attention level was little changed by these stimuli. These findings suggest that there are at least two independent cognitive factors that affect duration estimation. 相似文献

Watching another person take actions to complete a goal and making inferences about that person's knowledge is a relatively natural task for people. This ability can be especially important in educational settings, where the inferences can be used for assessment, diagnosing misconceptions, and providing informative feedback. In this paper, we develop a general framework for automatically making such inferences based on observed actions; this framework is particularly relevant for inferring student knowledge in educational games and other interactive virtual environments. Our approach relies on modeling action planning: We formalize the problem as a Markov decision process in which one must choose what actions to take to complete a goal, where choices will be dependent on one's beliefs about how actions affect the environment. We use a variation of inverse reinforcement learning to infer these beliefs. Through two lab experiments, we show that this model can recover people's beliefs in a simple environment, with accuracy comparable to that of human observers. We then demonstrate that the model can be used to provide real‐time feedback and to model data from an existing educational game. 相似文献

We examined how impression (such as safety, pleasantness, and impact), as well as emotional arousal and valence, evoked by viewing a picture affects temporal resolution of visual processing and perceived picture duration. In the first experiment as an index of temporal resolution of visual processing, we measured the noticeable duration of a monochrome picture after presenting a color picture. In the second experiment, we measured the duration of the picture presentation, which was equivalent to the duration of the presentation of a gray rectangle that should not evoke specifically safe or pleasant impressions. We found that the minimum duration in which an observer could notice a monochrome image in viewing a dangerous picture was shorter than that in viewing safe pictures. We also found that observers overestimated the duration of the picture presentation in viewing dangerous pictures. However, there was no significant correlation between the results of the two experiments. These results suggest that the basis for improvement of the temporal resolution in visual processing differs from that for the elongation of the perceived duration. 相似文献
