The current study analysed crashes identified in a large-scale naturalistic driving database to assess the prevalence of cognitive disengagement (i.e., purely cognitive distraction and mind wandering/microsleep) or episodes wherein the driver did not look away from the roadway during secondary task completion or wherein another clearly observable contributing crash factor was not present, and the driver's reaction to the crash showed symptoms of cognitive disengagement. The study found that <1% (95% CI [0.45, 1.66]) of higher severity crashes had a potential contributing crash factor of mind wandering/microsleep; ~1.5% (95% CI [0.83, 2.32]) had a potential contributing factor of purely cognitive distraction. The results suggest a relatively low prevalence of cognitive disengagement among automotive crashes compared with visual/manual secondary tasks. However, the current methodology is limited in that it does not account for instances where cognitive disengagement, in combination with other factors, may have led to crashes, potentially leading to conservative estimates. 相似文献

A set of ability tests from the Kit of Factor Referenced Cognitive Tests (Ekstrom, French and Harman, 1976, 1979), the EPQ, a Type A scale and a measure of Obsessionality were administered to 135 non-commissioned officers in the British Army at the beginning of an arduous ten-week training course in the Brecon Beacons. It was found that the 25 men (19%) who were unable to complete the training course did not differ from the others in any of the abilities measured, but were significantly more neurotic, and tended to be more extraverted, impatient and emotionally unrepressed. Personality factors are thus seen to contribute more to success or failure on such courses than simple cognitive abilities. 相似文献

The effects of group size, group status and trait valence (positive or negative stereotypes of in‐ and outgroup) on intergroup bias was studied in nation‐wide probability samples of majority and minority groups in Finland and Sweden, (N = 2479). Ethnolinguistic vitality was used as a proxy for status. It is argued that the specific history of real‐life intergroup relations has to be duly acknowledged when predicting main and interactive effects on intergroup bias in natural contexts. Supporting the predictions made, numerical group size showed a stable main effect; members of numerical minorities showed more bias than members of numerical majorities, regardless of trait valence. While status had no main effect, there was a significant interaction between status and size as well as between status and trait valence: intergroup bias was highest in the high status minority, and low status groups showed less bias than high status groups on negatively valenced traits. In fact, minority members showed the reverse of PNAE. In addition, majority members favoured the outgroup on negatively valenced traits, but favoured their ingroup on positively valenced traits. Different explanations for these results are discussed. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

It is widely argued that people with autism have difficulty processing ambiguous linguistic information in context. To investigate this claim, we recorded the eye-movements of 24 adolescents with autism spectrum disorder and 24 language-matched peers as they monitored spoken sentences for words corresponding to objects on a computer display. Following a target word, participants looked more at a competitor object sharing the same onset than at phonologically unrelated objects. This effect was, however, mediated by the sentence context such that participants looked less at the phonological competitor if it was semantically incongruous with the preceding verb. Contrary to predictions, the two groups evidenced similar effects of context on eye-movements. Instead, across both groups, the effect of sentence context was reduced in individuals with relatively poor language skills. Implications for the weak central coherence account of autism are discussed. 相似文献

ABSTRACT We tested a theoretical model of personality structures underlying patterns of intra-individual variability in contextualized appraisals. The KAPA (Knowledge-and-Appraisal Personality Architecture) model was tested experimentally among smokers appraising their efficacy to resist the urge to smoke in high-risk situations. In a novel design, we assessed self-knowledge and situational beliefs idiographically and employed cognitive priming to manipulate the accessibility of self-knowledge experimentally. The results confirmed the unique KAPA-model prediction that priming would affect appraisals in a contextualized manner. Priming positively valenced self-knowledge enhanced self-efficacy appraisals specifically within that subset of situations that were relevant to the primed knowledge. The results were consistent with the hypothesis that systems of self- and situational knowledge underlie consistency and variability in appraisals. 相似文献

Many animal species use reaching for food to place in the mouth (reach-to-eat) with a hand, and it may be a primitive movement. Although researchers (I. Q. Whishaw, 2005; A. N. Iwaniuk & I. Q. Whishaw, 2000; M. Gentiluci, I. Toni, S. Chieffi, & G. Pavesi, 1994) have described visual guidance of reaching in both normal and brain-injured human and nonhuman primates, researchers have not described the contribution of vision during advance of the limb to grasp food and during withdrawal of the limb with food to the mouth. To evaluate visual contributions, the authors monitored eye movements in young adults as they reached for food with and without vision. Participants visually engaged the target prior to the 1st hand movement and disengaged it as the food was grasped. Visual occlusion slowed limb advance and altered digit shaping but did not affect withdrawal. The dependence on visual control of advance but not withdrawal suggests that the reach-to-eat movement is a composite of 2 basic movements under visual and tactile/proprioceptive guidance, respectively. 相似文献

Research in psychology has reported that, among the variety of possibilities for assessment methodologies, summary evaluation offers a particularly adequate context for inferring text comprehension and topic understanding. However, grades obtained in this methodology are hard to quantify objectively. Therefore, we carried out an empirical study to analyze the decisions underlying human summary-grading behavior. The task consisted of expert evaluation of summaries produced in critically relevant contexts of summarization development, and the resulting data were modeled by means of Bayesian networks using an application called Elvira, which allows for graphically observing the predictive power (if any) of the resultant variables. Thus, in this article, we analyzed summary-evaluation decision making in a computational framework. 相似文献

When does morphological decomposition occur in visual word recognition? An increasing body of evidence suggests the presence of early morphological processing. The present work investigates this issue via an orthographic similarity manipulation. Three masked priming lexical decision experiments were conducted to examine the transposed-letter similarity effect (e.g., jugde facilitates JUDGE more than the control jupbe) in polymorphemic and monomorphemic words. If morphological decomposition occurs at early stages of visual word recognition, we would expect an interaction with transposed-letter effects. Experiment 1 was carried out in Basque, which is an agglutinative language. The nonword primes were created by transposing two letters that either crossed the morphological boundaries of suffixes or did not. Results showed a transposed-letter effect for non-affixed words, whereas there were no signs of a transposed-letter effect across morpheme boundaries for affixed words. In Experiment 2, this issue was revisited in a non-agglutinative language (Spanish), with prefixed and suffixed word pairs. Again, results showed a significant transposed-letter effect for non-affixed words, whereas there were no signs of a transposed-letter effect across morpheme boundaries for affixed words (both prefixed words and suffixed words). Experiment 3 replicated the previous findings, and also revealed that, for polymorphemic words, transposed-letter priming effects occurred for within-morpheme transpositions. Taken together, these findings support the view that morphological decomposition operates at an early stage of visual word recognition. 相似文献

We used measures of positive affect and emotional expression to distinguish and better understand veterans with PTSD with symptom overreporting presentation styles. Based on prior research, symptom overreporting was defined as scores greater than eight on the F(p) (Infrequency-Psychopathology) scale of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Data were drawn from an archival dataset of 227 combat veteran outpatients. Results were consistent with theory and research on the distinction between negative and positive affect. Major findings indicated that (a) veterans endorsing greater anhedonia had a greater likelihood of being classified as a symptom overreporter (controlling for PTSD symptoms), and (b) compared to non-symptom overreporting veterans, overreporters showed greater congruency in their presentation of diminished positive affect and their expression across self- and clinician-ratings. Our data suggest that diminished positive emotions and their behavioral expression are uniquely associated with veterans' psychological experiences, providing insight into the nature of symptom overreporters. 相似文献
