Differential item functioning (DIF) assessment is key in score validation. When DIF is present scores may not accurately reflect the construct of interest for some groups of examinees, leading to incorrect conclusions from the scores. Given rising immigration, and the increased reliance of educational policymakers on cross-national assessments such as Programme for International Student Assessment, Trends in International Mathematics and Science Study, and Progress in International Reading Literacy Study (PIRLS), DIF with regard to native language is of particular interest in this context. However, given differences in language and cultures, assuming similar cross-national DIF may lead to mistaken assumptions about the impact of immigration status, and native language on test performance. The purpose of this study was to use model-based recursive partitioning (MBRP) to investigate uniform DIF in PIRLS items across European nations. Results demonstrated that DIF based on mother's language was present for several items on a PIRLS assessment, but that the patterns of DIF were not the same across all nations. 相似文献

To examine the extent of automaticity of emotional face processing in high versus low trait anxious participants, event-related
potentials (ERPs) were recorded to emotional (fearful, happy) and neutral faces under varying task demands (low load, high
load). Results showed that perceptual encoding of emotional faces, as reflected in P1 and early posterior negativity components,
was unaffected by the availability of processing resources. In contrast, the postperceptual registration and storage of emotion-related
information, as reflected in the late positive potential component at frontal locations, was influenced by the availability
of processing resources, and this effect was further modulated by level of trait anxiety. Specifically, frontal ERP augmentations
to emotional faces were eliminated in the more demanding task for low trait anxious participants, whereas ERP enhancements
to emotional faces were unaffected by task load in high trait anxious participants. This result suggests greater automaticity
in processing affective information in high trait anxious participants. 相似文献

Category training can induce category effects, whereby color discrimination of stimuli spanning a newly learned category boundary is enhanced relative to equivalently spaced stimuli from within the newly learned category (e.g., categorical perception). However, the underlying mechanisms of these acquired category effects are not fully understood. In the current study, Event-Related Potentials (ERPs) were recorded during a visual oddball task where standard and deviant colored stimuli from the same or different novel categories were presented. ERPs were recorded for a test group who were trained on these novel categories, and for an untrained control group. Category effects were only found for the test group on the trained region of color space, and only occurred during post-perceptual stages of processing. These findings provide new evidence for the involvement of cognitive mechanisms in acquired category effects and suggest that category effects of this kind can exist independent of early perceptual processes. 相似文献

I am the daughter of earth and water, And the nursling of the sky. Percy Bysshe Shelley, “The Cloud,” 1820
Abstract Looking at the night sky, we may seem cosmic dwarfs, overwhelmed with a sense of otherness, abyss, lostness. But humans alone enjoy such celestial awe. We can move to a sense of the beholder's celestial ancestry and ongoing relatedness in “our cosmic habitat.” That account joins aesthetics with mathematics, finds dramatic interrelationships gathered under “the anthropic principle,” and considers meteorological aesthetics. The wonder is as much this Homo sapiens with mind enough to search the universe. What is out there is inseparably linked with what is down here. We are at home in the universe. The glory is both over our heads and in our heads. 相似文献

Abstract This paper supports the contention that the brain stores memories in the form of a central representation that is accessed by both physical preparation and execution and, more importantly, by motor imagery associated with this preparation and execution. Considerable evidence in support of shared central and vegetative structures suggests that sport psychologists should consider more closely aspects of the performer's responses to the physical skill when providing imagery interventions and not rely on “traditional,” more clinically orientated, methods of delivery. Many texts provide a schedule of factors and techniques for psychologists, athletes, and coaches to consider but with a limited theoretical explanation of why these factors are the crucial concerns. We, therefore, propose an evidence-based, 7-point checklist that includes: physical, environmental, task, timing, learning, emotional, and perspective elements of imagery delivery highlighting the minimum requirement areas in which sport psychologists should monitor the equivalence to the physical task in order to enhance the efficacy of their practice. 相似文献
