Distraction is a common cause of accidents (e.g. NHTSA, 2009), and different distraction conditions influence the driving behaviour in a specific way. Despite a lot of research in this area, most studies concentrate on perception errors as a result of visual distraction. The effects of different distraction conditions on higher cognitive processes are still unclear. The fact that accidents happen even if the drivers perceive all relevant information implies that cognitive factors contribute to accidents, too. For this reason, this study was conducted to investigate how different distraction conditions influence the anticipation of events in a car–following scenario. Anticipation is required to know what will happen next, and to react adequately to the situation. In a driving simulator, scenarios with different manoeuvres of a preceding car were created to generate various anticipations and therefore a different adaptation of the driving behaviour. Additionally, a cognitive and a visual secondary task were introduced. The question was in which way either a cognitive or visual distraction influences the generation of anticipations and the construction of an appropriate situation model.The results indicate that in the phase when the preceding car showed braking manoeuvres, drivers prolonged their safety distance only when being visually distracted which is probably done to compensate for this visual distraction. This compensation ensued to some extent in the second phase where the preceding cars drove with a constant speed. Additionally, drivers who were visually distracted went somewhat slower when the car in front had braked in phase one. Thus, the drivers seemed to anticipate that the car might brake again and adapted their speed accordingly. This was not found in drivers with cognitive distraction. Thus, cognitive distraction seems to disturb this anticipation.Finally, at an intersection, drivers with visual distraction had a smaller TTC and a higher velocity when the car in front made an unexpected turn. Thus, the impairment of perception due to the visual distraction leads to a slower reaction as compared to a cognitive distraction. Overall, cognitive distraction influences the anticipation of possible future actions of other car drivers negatively while visual distraction deteriorates perception and thus the reaction to critical, sudden events. Thus, different intervention strategies are required to prevent these kinds of accidents. 相似文献

Sound categorisation plays a crucial role for processing ecological and social stimuli in a species’ natural environment.
To explore the discrimination and evaluation of sound stimuli in human babies and nonhuman primates, a reciprocal habituation-dishabituation
paradigm has been successfully introduced into auditory research. We applied the reciprocal paradigm for the first time to
a non-primate mammal, the tree shrew (Tupaia belangeri), to examine to what extent non-primate mammals share the ability to evaluate communication calls with primates. Playback
stimuli were three types of communication calls, differing distinctively in context and acoustic structure, as well as two
artificial control sounds, differing solely in frequency. We assessed the attention towards the playback stimuli by the latency
to respond to the test stimulus. Subjects evaluated pairs of communication call types as well as the artificial playback stimuli.
Attention towards the test stimuli differed significantly in strength for one pair of communication calls, with subjects dishabituating
faster to one category than the other. The comparison of a second pair of communication calls did not show significant differences.
Interestingly, subjects also evaluated the artificial control sounds. Findings are only partly in line with results on human
and non-human primates. They provided first evidence that in non-primate mammals acoustic evaluation is not solely affected
by the sound-associated context but is also linked to unusualness and acoustic cues, such as peak frequency. 相似文献

The present study examines the influence of viewing position, experience, processing time, and attention on shape constancy in gymnastics judging. In an experiment, 40 gymnastics judges and as many laypeople were presented with a series of photographs that show athletes holding a ‘cross on rings’. They were simultaneously taken from different viewpoints. Participants had to judge how many degrees the arms deviated from horizontal for each picture. One half of the participants had a secondary task, to judge the duration of the picture presentation, which varied also. The overall performances of the gymnastics judges were much better than those of the laypeople, and in contrast to the lay‐judgments, they were not influenced by the secondary task. However, gymnastics judges were still significantly influenced by viewpoint, that is, their error rate increased with an increase in deviation from a frontal view.

Fantasy proneness, but not self-reported trauma is related to DRM performance of women reporting recovered memories of childhood sexual abuse 总被引:1,自引:0,他引:1

Extending a strategy previously used by , we administered a neutral and a trauma-related version of the Deese-Roediger-McDermott paradigm to a sample of women reporting recovered (n=23) or repressed memories (n=16) of childhood sexual abuse (CSA), women reporting having always remembered their abuse (n=55), and women reporting no history of abuse (n=20). We found that individuals reporting recovered memories of CSA are more prone than other participants to falsely recalling and recognizing neutral words that were never presented. Moreover, our study is the first to show that this finding even held when trauma-related material was involved. Correlational analyses revealed that fantasy proneness, but not self-reported traumatic experiences and dissociative symptoms were related to false recall and false recognition. 相似文献

The present study assessed fear of hurricanes in children who had been confronted with this natural event (i.e., Antillean children, n=161). Their fear levels were compared to those of children who are unfamiliar with such an event (i.e., Belgian children, n=185). Antillean children reported significantly higher levels of fear of storms than Belgian children did, thus providing support for the notion that exposure to dangerous events promotes children's fears of those events. Surprisingly, however, Antillean children had lower scores on the 'Hurricanes' item than Belgian children. Plausibly, differences in how children interpreted this item may have accounted for this unexpected finding. That is, ratings of Antillean children were probably based on actual experiences with hurricanes, whereas scores of Belgian children presumably reflected appraisal of threat in case they would be confronted with such an event. Implications of this finding for the assessment of childhood fears are briefly discussed. 相似文献

In this article, we describe a multistudy project designed to explain observed cross-national differences in risk taking between respondents from the People’s Republic of China and the United States. Using this example, we develop the following recommendations for cross-cultural investigations. First, like all psychological research, cross-cultural studies should be model based. Investigators should commit themselves to a model of the behavior under study that explicitly specifies possible causal constructs or variables hypothesized to influence the behavior, as well as the relationship between those variables, and allows for individual, group, or cultural differences in the value of these variables or in the relationship between them. This moves the focus from a simple demonstration of cross-national differences toward a prediction of the behavior, including its cross-national variation. Ideally, the causal construct hypothesized and shown to differ between cultures should be demonstrated to serve as a moderator or a mediator between culture and observed behavioral differences. Second, investigators should look for converging evidence for hypothesized cultural effects on behavior by looking at multiple dependent variables and using multiple methodological approaches. Thus, the data collection that will allow for the establishment of conclusive causal connections between a cultural variable and some target behavior can be compared with the creation of a mosaic. 相似文献

Pigeons learned a successive conditional visual discrimination on vertically and horizontally arranged pairs of stimulus-response keys. When the discriminanda were two similar hues the pigeons' performance was significantly better on the vertical than on the horizontal task. This was also found in an experiment in which the subjects could see only monocularly. When, however, the discriminative stimuli were patterns of different orientation or markedly dissimilar hues then the performance on the horizontal task had an advantage over that on the vertical one. A horizontal advantage also obtained when similar hues were discriminated on keys clustered closely together. Pigeons thus seem more adept at solving successive conditional discriminations on horizontal than on vertical pairs of keys except when similar hues are displayed on widely separated keys where the reverse is true. It is hypothesized that colour vision inequalities due to regional retinal differentiations are responsible for this latter effect. 相似文献

A theory of perceived risk and attractiveness 总被引:1,自引:0,他引:1

People judged both the attractiveness and risk of lotteries to win or lose money. The lotteries were designed to test whether risk and attractiveness judgments show systematic deviations from the simple sum of probability-by-utility-products analogous to (S)EU theory. Our results led to an alternative combination rule for probability and outcome information, with a relative weight averaging component and a configural (i.e., sign- or rank-dependent) probability weighting component. Ratings of risk and attractiveness were negatively correlated, but the two tasks showed systematic differences in the rank order of judgments. Both judgments could be fit by the same configural relative weight averaging model, but with different parameters (especially the sign-dependent probability weighting functions). Risk judgments were more sensitive to the probability of losses and zero outcomes compared to attractiveness judgments, which were more sensitive to the probability of gains. There were individual differences on the extent of this difference in probability weights between risk and attractiveness judgments. 相似文献
