Experts often appear to perceive time differently from novices. The current study thus examined perceptions of time as a function of domain expertise. Specifically, individuals with high or low levels of knowledge of American football made judgements of duration for briefly presented words that were unrelated to football (e.g., rooster), football specific (e.g., touchdown), or ambiguous (e.g., huddle). Results showed that high-knowledge individuals judged football-specific words as having been presented for a longer duration than unrelated or ambiguous words. In contrast, low-knowledge participants exhibited no systematic differences in judgements of duration based on the type of word presented. These findings are discussed within a fluency attribution framework, which suggests that experts' fluent perception of domain-relevant stimuli leads to the subjective impression that time slows down in one's domain of expertise. 相似文献

Rats judged inter-reward intervals (IRIs) in a two-alternative, forced-choice task. The IRI was either short (S) or long (L). At the end of each IRI, two response levers were inserted into the box. A press to the lever designated as correct or incorrect produced a large (3-5 food pellets) or small (1 pellet) reward, respectively. Psychophysical functions were obtained by testing intermediate IRIs, which were followed by the small reward, independent of the response location. S and L intervals were manipulated across groups, as specified (in seconds) by the group name, S-L: 3-12 (n=12), 25-100 (n=12), and 50-200 (n=7). The psychophysical functions (p[L] vs. IRI) were ogival in shape and had bisection points (p[S]=p[L]=0.5) near the geometric mean of S and L intervals. The psychophysical functions did not superimpose in relative time (IRI/L). Instead, 3-12 was timed with greater relative sensitivity than were 25-100 and 50-200. 相似文献

A single session intervention was given individually to 4 adults in order to assist them in achieving their personal goals by improving their behavioral skills for achieving the goals and their conceptual understanding of & #x201C;how to & #x201D; attain these goals. The method was based on a brain-ability analysis of understanding & #x201C;conservation & #x201D; on Jean Piaget's conservation tasks combined with Paul and Gail Dennison's Brain Gym & #x201C;balance & #x201D; procedure. My & #x201C;whole brain understanding & #x201D; model (C. A. Wolfsont, 1999, 2000) and M. L. Commons et al.'s Hierarchical Complexity Scoring System manual were used to analyze the verbal protocols (M. L. Commons et al., 1992; Commons, Danaher, & Meaney, 2000). Increases were found in the participants' conceptual understanding and in the complexity of their performance. 相似文献

We examined predictors of media multitasking in Chinese adolescents from 3 contexts: characteristics of the media user, types of media use and family media contexts. Three hundred and twenty adolescents, 11–18 years of age, completed questionnaires to measure media use, impulsivity, sensation seeking, time management disposition and family media environment. The results showed that media multitasking was positively correlated with age and total media use time. Participants with high levels of impulsivity and sensation seeking reported more multitasking behaviour. Multitasking was negatively correlated with time management. Children from media‐oriented families often engage in more multitasking. What's more, social networking sites use and music use can mediate the effect of individual and family factors on media multitasking. 相似文献

Two studies investigated cognitive mechanisms that may be associated with people's tendency to maximize. Maximizers are individuals who are spending a great amount of effort in order to find the very best option in a decision situation, rather than stopping the decision process when they encounter a satisfying option. These studies show that maximizers are more future oriented than other people, which may motivate them to invest the extra energy into optimal choices. Maximizers also have higher numerical skills, possibly facilitating the cognitive processes involved with decision trade‐offs. 相似文献

Existing fatigued driving analysis methods mainly focus on lateral driving performance by using the measurements related to the steering wheel or lane position. There is a lack of research on longitudinal car following behavior. In this study, 40 professional drivers are invited to participate in field expressway driving experiment, lasting at least for 6 h. During the test, their performance is measured in terms of their self-reported fatigued driving level according to the Karolinska Sleepiness Scale (KSS), the PERcentage of eye CLOSures (PERCLOS) and the Time Headway (THW). Then the effects of the fatigued driving level on car following behavior are evaluated. The results indicate that the fatigue level (for both KSS and PERCLOS) has significantly impact on THW parameters, including the mean, standard deviation and minimum THW. An increase in KSS and PERCLOS leads to a lower mean and minimum THW. Meanwhile, the standard deviation of THW increases with the increase of KSS and PERCLOS. In conclusion, this study found that a higher fatigue level leads to the driver keeping a smaller THW when following another vehicle and choosing shorter THW to make lane change. More deviation of car following performance was also found with the increase of fatigue level. Therefore, the findings of this study can be used to explain fatigue as one of the major reasons for rear-end collisions. Also, the research findings demonstrate the impact of fatigue on driving behavior in terms of car following performance, which can be used as a measurement for monitoring fatigued drivers. 相似文献

It seems uncontroversial that Dalton wrongly believed that atoms are indivisible. However, the correct analysis of Dalton’s belief and the way it relates to contemporary beliefs about atoms is, on closer inspection, far from straightforward. In this paper, I introduce four features that any candidate analysis is plausibly bound to respect. I argue that theories that individuate concepts at the level of understanding are doomed to fail in this endeavor. I formally sketch an alternative and suggest that cases such as the one presented provide support for the claim that the genuine source for concept individuation is public sharable thought. 相似文献

The Criminal Justice and Public Order Act 1994 (England and Wales) modified suspects' right to silence during police questioning and required a new police caution. The current 37-word caution was introduced after it was found that a proposed 60-word draft version was too complex. The results of the present study show that, although more succinct, the current caution is no easier to explain. Even under optimal conditions, when the participants could focus on each sentence in turn, only 1 in 10 of the general population (n=15), 6 in 10 of A-level students preparing for university (n=72) and 9 in 10 police officers (n=21) demonstrated their understanding by explaining all three sentences correctly. For all groups, the difficulties were more marked when the caution was presented in its entirety, as would happen in real life. The complexity of the caution has serious implications for suspects in police detention. © 1998 John Wiley & Sons, Ltd. 相似文献
