When observers localize the vanishing point of a moving target, localizations are reliably displaced beyond the final position, in the direction the stimulus was travelling just prior to its offset. We examined modulations of this phenomenon through eye movements and action control over the vanishing point. In Experiment 1 with pursuit eye movements, localization errors were in movement direction, but less pronounced when the vanishing point was self‐determined by a key press of the observer. In contrast, in Experiment 2 with fixation instruction, localization errors were opposite movement direction and independent from action control. This pattern of results points at the role of eye movements, which were gathered in Experiment 3. That experiment showed that the eyes lagged behind the target at the point in time, when it vanished from the screen, but that the eyes continued to drift on the targets' virtual trajectory. It is suggested that the perceived target position resulted from the spatial lag of the eyes and of the persisting retinal image during the drift. 相似文献

Representational momentum (RM) refers to the tendency of participants to “remember” the stopping point of an event as being farther along in the direction of movement than it was in reality (Freyd & Finke, 1984). Our aim was twofold: (1) Test for the impact of domain-specific expertise (here, automobile driving) on RM, using films of road scenes, and (2) find out whether the improved anticipation ability that comes with greater expertise is transferred to scenes from domains that are far-removed from the person's domain of expertise. Two experiments were conducted in which experienced and inexperienced automobile drivers performed a movement-anticipation task on realistic road scenes (Experiment 1), with stimuli that were very different from those found in their domain of expertise (Experiment 2). These studies pointed out some properties of representational momentum, and showed that RM is dependent upon knowledge acquired by participants in specific domains. Our research also showed that expertise in automobile driving can modulate RM in road-scene perception (i.e., the cognitive characteristics of the observer can modulate the magnitude of the RM effect) but that expertise in automobile driving is not transferred to dissimilar domains. 相似文献

Conservatism has an essence, or so I argue. Typical of the conservative attitude is to take what is an established fact or order to be worthy of preservation, precisely because it is well established. The question what fact is established must be answered in a context, and people of different political bent answer it differently. This is why we have left‐wing as well as right‐wing conservatism, sharing a common rationale. In my Conservatism for Our Time I discuss various different aspects of this rationale, and my answer to certain strictures raised by Robert Grant concerns several of them. The most important concerns a conservative or traditionalist criticism of rationalism. This criticism has been developed by ‐ among others ‐Michael Oakeshott. In my book, and in my answer to Grant, I defend and elaborate on this criticism. 相似文献

The present experimental study adds to the emerging line of psycholegal research focusing on true and false intentions. It is the first to examine mock suspects' (N = 120) counter‐interrogation strategies in investigative interviews in which they anticipate questions on their intentions. As planning is an inherent part of many intentions, mock suspects were, in addition to questions on their intentions, asked a set of questions that pertained to the planning phase in which they formed their intentions. Besides ratings of the anticipation and difficulty of the questions, participants were asked to provide their principal strategy for being perceived as truthful. Both truth tellers and liars perceived the questions on the planning phase as significantly more unanticipated than the questions on their intentions. Furthermore, liars perceived the questions on the planning phase as more difficult to answer than did truth tellers. Liars and truth tellers differed with respect to their principal strategy employed for being perceived as truthful. Liars' most commonly used strategy was to stick to the cover story, whereas truth tellers' most common strategy was to be honest. The results are discussed in relation to the unanticipated questions approach and psychological concepts such as the illusion of transparency. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Prior research suggests that perceived performance of a product or a service is directly linked to postpurchase satisfaction. We argue that this causal relationship might be a measurement artifact and/or insufficient modeling of the satisfaction process rather than an accurate assessment of how consumers form satisfaction judgments. To test our hypotheses, a 2 x 2 x 2 (Performance x Expectations x Needs) factorial design was used with 2 types of perceived performance measures (value-laden and objective). The findings demonstrate that the observed direct link from perceived performance to overall satisfaction diminishes when more objective perceived performance indicators replace the commonly used value-laden measures. Furthermore, desire-congruency was found to contribute independently to satisfaction over and above a disconfirmation-of-expectations standard. In fact, desire-congruency was found to be a better predictor of satisfaction than disconfirmation-of-expectations. Finally, our results suggest that the direct performance–satisfaction link becomes insignificant when the modeling of the satisfaction process is improved. Taken together, these findings support the view that the frequently observed high correlations between perceived performance and satisfaction might be a reflection of the type of measures used and/or insufficient capturing of the evaluative process leading to satisfaction, rather than support for a direct causal link. 相似文献

According to the modulation hypothesis, arousal is the crucial factor in the emotional enhancement of memory (EEM). However, the multifactor theory of the EEM recently proposed that cognitive characteristics of emotional stimuli, e.g., relatedness and distinctiveness, also play an important role. The current study aimed to investigate the individual contribution of arousal to the neural correlates of the EEM by controlling for these additional cognitive factors. We observed the characteristic neuronal correlates of the EEM, in particular enhanced activity in the amygdala and hippocampus, which provides evidence for an arousal-driven EEM in the amygdala as proposed by the modulation hypothesis. 相似文献

Acute stress modulates multiple memory systems in favor of caudate nucleus-dependent stimulus-response and at the expense of hippocampus-dependent spatial learning and memory. We examined in mice and humans whether chronic stress has similar consequences. Male C57BL/6J mice that had been repeatedly exposed to rats ("rat stress") used in a circular hole board task significantly more often a stimulus-response strategy (33%) than control mice (0%). While velocity was increased, differences in latency to exit hole, distance moved or number of holes visited were not observed. Increased velocity and performance during retention trials one day later indicates altered emotionality and motivation to explore in rat stressed mice. Forty healthy young men and women were split into "high chronic stress" and "low chronic stress" groups based on their answers in a chronic stress questionnaire ("Trier Inventory of Chronic Stress"-TICS) and trained in a 2D task. A test trial immediately after training revealed that participants of the "high chronic stress" group used the S-R strategy significantly more often (94%) than participants of the "low chronic stress" group (52%). Verbal self-reports confirmed the strategy derived from participants' choice in the test trial. Learning performance was unaffected by the chronic stress level. We conclude that one consequence of chronic stress is the shift to more rigid stimulus-response learning, that is accompanied by changes in motivational factors in mice. 相似文献
