In 2005, the regulation of signage on German highways was changed and now allows supplementary signs. These signs are installed below direction signs and inform about the services offered on motorway service areas. Being advertisement, the supplementary signs bear the risk to distract drivers looking for directional information. To study the influence of supplementary signs, four experiments (N = 30) were conducted. Experiment 1 used the phenomenon of change blindness as an indicator for the allocation of attention. It could be shown that drivers searching for a specific direction direct nearly no attention to the supplementary signs. In experiment 2 and 3, the influence of the supplementary signs on perceptional threshold for directional information and on self-chosen perception times was measured. Neither the perceptional threshold nor perception times freely chosen by the participants were negatively affected by the supplementary signs. The last experiment analyzed the influence of supplementary signs on driver reaction in a critical driving situation in a driving simulator study. Here, supplementary signs had no negative impact on collision rate and reaction time. Based on the results, it is concluded that drivers use effective attentional strategies while searching for directional information. In the experiments no negative effects of the supplementary signs could be found. 相似文献

We examined whether semantic processing occurs without awareness using continuous flash suppression (CFS). In two priming tasks, participants were required to judge whether a target was a word or a non-word, and to report whether the masked prime was visible. Experiment 1 manipulated the lexical congruency between the prime-target pairs and Experiment 2 manipulated their semantic relatedness. Despite the absence of behavioral priming effects (Experiment 1), the ERP results revealed that an N4 component was sensitive to the prime-target lexical congruency (Experiment 1) and semantic relatedness (Experiment 2) when the prime was rendered invisible under CFS. However, these results were reversed with respect to those that emerged when the stimuli were perceived consciously. Our findings suggest that some form of lexical and semantic processing can occur during CFS-induced unawareness, but are associated with different electrophysiological outcomes. 相似文献

The purpose of this randomised crossover study is to validate the Korean version of the Affective Go/No‐go (AGN) test. The Korean words for the AGN test were selected after careful evaluation of emotional valences, word length and frequency. Fifteen Korean advanced learners of English were administered both Korean and English versions, yielding 30 data points. The performance of both language versions was compared for each of the AGN test parameters (response latency, commission error and omission error) using two‐way analysis of variance (ANOVA). Intraclass correlation coefficients (ICCs) were estimated to evaluate associations between the two versions. The ICCs were high for response latencies of all valences and commission errors of positive and neutral words, but not for that of negative words and omission errors of all valences. A similar pattern of test results, as revealed by the high ICCs and non‐significant interaction effects between language and word valence, suggests that the psychometric properties of the AGN test may be comparable over different language versions. 相似文献

The authors investigated how visual information from the nondominant and dominant eyes are utilized to control ongoing dominant hand movements. Across 2 experiments, participants performed upper-limb pointing movements to a stationary target or an imperceptibly shifted target under monocular-dominant, monocular-nondominant, and binocular viewing conditions. Under monocular-dominant viewing conditions, participants exhibited better endpoint precision and accuracy. On target jump trials, participants spent more time after peak limb velocity and significantly altered their trajectories toward the new target location only when visual information from the dominant eye was available. Overall, the results suggest that the online visuomotor control processes that typically take place under binocular viewing conditions are significantly influenced by input from the dominant eye. 相似文献

Movement preparation of bimanual asymmetric movements takes more time than bimanual symmetric movements in choice reaction-time conditions. This bimanual asymmetric cost may be caused by increased processing demands on any stage of movement preparation. The authors tested the contributions of each stage of movement preparation to the asymmetric cost by using the additive factors method. This involved altering the stimulus contrast, response compatibility, and response complexity. These manipulations changed the processing demands on stimulus identification, response selection, and response programming, respectively. Any manipulation with a larger reaction time cost than control suggests that stage contributes to the bimanual asymmetric cost. The bimanual asymmetric cost was larger for incompatible stimuli, which supports that response selection contributes to the bimanual asymmetric cost. 相似文献

Whether intentional suppression of an unpleasant or unwanted memory reduces the ability to recall that memory subsequently is a contested issue in contemporary memory research. Building on findings that similar processes are recruited when individuals remember the past and imagine the future, we measured the effects of thought suppression on memory for imagined future scenarios. Thought suppression reduced the ability to recall emotionally negative scenarios, but not those that were emotionally positive. This finding suggests that intentionally avoiding thoughts about emotionally negative episodes may inhibit representations of those memories, progressively reducing their availability to recall. 相似文献

Scholars of aggression in educational settings have long been interested in studying sanctions against academic achievement. Though many studies focus on minority students’ experiences, research has not tested the relationship between academic success and peer victimization within individual groups of students that are representative of the United States’ racial and ethnic diversity. The same can be said of studies of extracurricular activities and peer victimization, despite the academic involvement and enrichment those activities entail. This study examines how academic success and extracurricular activities impact the risk of being victimized by peers through verbal, physical, and other bullying-related incidents. Further, this relationship is compared across four racial/ethnic categories (Asian, Black, Hispanic, White). The study analyzes data from the most recent racially diverse and nationally representative education data set (the 2002 Education Longitudinal Study) to do so. Multilevel regression analyses indicate that participation in academic extracurricular activities and academic effort put students at increased risks for victimization. White students’ victimization helps to account for these relationships. The findings not only provide evidence of stigma against academically enriching activities, but also provide additional evidence against the assumption that only marginalized minority groups are stigmatized for academic effort and involvement. 相似文献
