Abstract: We examined the effect of the stimulus type and semantic categorization of the unexpected stimulus on sustained Inattentional Blindness (IB). Results showed that observers could establish attentional set based on a higher level of semantic categorization, which tuned one's attention to prioritizing semantic content over others. The unexpected stimulus, congruent with the attended objects in semantic categorization, was more likely to be noticed, whereas the incongruent semantic stimulus seemed to be unseen. Semantic category‐level attentional set played a crucial role in breaking through IB. The semantically congruent Chinese characters stimulus was detected and recognized more often than a semantically congruent picture stimulus, indicating that Chinese characters had more power to attract attention to escape sustained IB than pictures involved in visual processing. Presumably the finding of Chinese characters breaking through IB more easily might be due to the fact that Chinese characters look more distinct from pictures, rather than Chinese characters being processed more easily. Further research should be taken to test the semantic processing efficiency between pictures and Chinese characters in sustained IB. 相似文献

We have investigated the formation process of α′-martensite from the γ-phase induced by external strain using in situ synchrotron diffraction experiments, combined with Lorentz transmission electron microscopy (TEM) and high-resolution TEM observations. It is clearly demonstrated that ε-martensite with hexagonal symmetry appears as an intermediate structure during the plastic deformation of SUS304 stainless steel. In addition to stacking faults and dislocations, interfaces between the twin structures presumably play a key role in the formation of ε-martensite. 相似文献

ABSTRACT. The current experimental study examined sense of coherence (SOC) as a predictor of the effect of induced stress (time limit and posing a threat) on the level of overall cognitive performance (based on three subscales: mathematics, shapes, and analogies). Results indicated the following: (a) induced stress (experimental group, n = 80) scored lower on the overall cognitive score, compared to the no-stress (control group, n = 81); (b) subjects in the stress group with higher SOC performed better on the overall cognitive score, compared to subjects with lower SOC; however, in the no-stress group there was no significant effect of SOC on cognitive performance; (c) females performed lower on the overall cognitive performance, compared to males regardless of type of group; and (d) SOC predicted equally for males and females overall cognitive performance. 相似文献

In the present study, we investigated how 3- and 4-year-old children perceived mirror-image stimuli traced on their foreheads. First, the subjects were taught matching-to-sample tasks with symmetrically shaped and asymmetrically shaped figures (called mirror-image stimuli) on cards. Then the subjects were taught cutaneous perception of a figure traced by the experimenter's finger on the forehead. Last, the subjects were tested with mirror-image stimuli in cutaneous perception tasks. The results of these experiments indicated that the subjects who could discriminate the mirror-image stimuli could also perceive asymmetrical stimuli as mirror reversals. 相似文献

Child abuse has been frequently associated with adult aggression in its many forms. The Point Subtraction Aggression Paradigm (PSAP) is a popular laboratory‐based procedure derived from the retaliatory responses of participants engaged in a monetary‐reinforced computer game. PSAP responses have been found to discriminate between participants with and without violent, antisocial, substance abuse, and even contact‐sport athletic histories. The present study provided an initial test of the sensitivity of the PSAP and the Overt Aggression Scale (OAS) in discriminating between college students (n=28) with and without reported histories of recurrent physical abuse as defined by incidents of being pushed, shoved, struck, punched, or threatened with physical violence by a parent more than once every six weeks over 15 years of upbringing. PSAP responses were substantially higher (d=2.1) among participants reporting histories of recurrent parental physical abuse, with 46% (as opposed to 0% for controls) of these individuals generating PSAP responses in excess of 400 (average found for violent parolees). Group differences on the OAS were also considerable (>1 SD). Larger factorial designs examining relationships between a range of developmental variables (e.g., domestic abuse, physical abuse, sexual abuse, parental divorce, family climate, etc.) and adult PSAP responding may help advance present knowledge regarding the impact of childhood adversity on psychological development.

The legacy of Nisbett and Wilson’s classic article, Telling More Than We Can Know: Verbal Reports on Mental Processes (1977), is mixed. It is perhaps the most cited article in the recent history of consciousness studies, yet no empirical research program currently exists that continues the work presented in the article. To remedy this, we have introduced an experimental paradigm we call choice blindness [Johansson, P., Hall, L., Sikström, S., &; Olsson, A. (2005). Failure to detect mismatches between intention and outcome in a simple decision task. Science, 310(5745), 116–119.]. In the choice blindness paradigm participants fail to notice mismatches between their intended choice and the outcome they are presented with, while nevertheless offering introspectively derived reasons for why they chose the way they did. In this article, we use word-frequency and latent semantic analysis (LSA) to investigate a corpus of introspective reports collected within the choice blindness paradigm. We contrast the introspective reasons given in non-manipulated vs. manipulated trials, but find very few differences between these two groups of reports. 相似文献

In recent years, much has been learned about the strategic and organizational contexts of suicide attacks. However, motivations of the agents who commit them remain difficult to explain. In part this is because standard models of social learning as well as Durkheimian notions of sacrificial behavior are inadequate in the face of the actions of human bombers. In addition, the importance of organizational structures and practices in reinforcing commitment on the part of suicide recruits is an under-explored factor in many analyses. This essay examines the potential applicability of evolutionary models of altruism to the understanding of commitment to suicide on the part of terrorist organizational recruits. Three evolutionary models of sacrificial behavior in nonhuman species and many categories of human behavior are explored cross-organizationally: reciprocity, inclusive fitness theory, and induced altruism. Reciprocal altruism is unlikely to be a major motivator in suicide attacks because the costs exhibited by attackers are too high to be adequately compensated. However, the role of evolved self-deception in perceptions of personal death, and thus of rewards in the afterlife, is potentially illuminating. Inclusive fitness theory can help explain the motivations of attackers because rewards to kin often are offered by organizations to suicide recruits. However, suicide bombers also often act out of revenge for the loss of or injury to relatives, and inclusive fitness theory generally, as well as more specific theoretical models of retaliatory aggression, may not adequately account for the bombers' actions. Predictions from induced altruism theory appear to be well supported because suicide terror organizations tend to be tightly structured around practices intended to maintain and reinforce commitment though the manipulation of kinship-recognition cues. 相似文献

与药物有关的肝毒性是一个严重的健康问题,广泛影响着患者、医疗机构和政府监管机构.另外,由于久坐的生活方式和热量过度摄取,我们还面临着肥胖和非酒精性脂肪性肝病（NAFLD）的流行和困扰,因为肥胖和/或NAFLD提高各种疾病的风险,成为影响公众健康的又一个主要问题,这些患者平均使用药物的量远高于非肥胖患者.越来越多的证据表明,某些药物能够增加肥胖和NAFLD患者药物诱发肝损伤（DILI）的风险.因此,我们应该重视和防治肥胖和NAFLD患者DILI的发生. 相似文献

Perceptual fluctuations experienced during motion-induced blindness (MIB) have been characterized as the result of a competition between representations of the moving mask and stationary (or slowly moving) targets (Bonneh, Cooperman, & Sagi, 2001). While there is evidence to support a local influence of the mask on target disappearance, what is not yet clear is whether the global properties of the mask can likewise impact disappearance. In the present study, we investigated the presence of a global effect of the mask on MIB by manipulating global motion properties of the mask while controlling its local motion properties surrounding the target. Results showed a significant impact of the global mask properties on the observed degree of disappearance. We also tested for a complementary local effect by comparing conditions in which we manipulated local mask properties while controlling global properties. This analysis did not yield evidence for a local effect, although this may have been due to our weaker manipulation of local mask properties compared to previous studies. Overall, the present results highlight a key role of global stimulus representations in producing the perceptual disappearances observed in MIB. 相似文献
