At a top psychology journal, Psychological Science (PS), submissions peak during the summer months. We tested whether this seasonal submission bias decreases the likelihood of a paper being accepted in that period. Month of submission data was obtained for all 575 publications in PS for the period 2003–2006. Whereas submissions to PS were higher in the summer, there was no evidence that most accepted publications were originally submitted in the summer. Thus, contributors submit to PS when the likelihood of acceptance is the lowest – creating their own entrance barrier. A similar seasonal pattern was not identified for Personality and Social Psychology Bulletin, another top psychology journal. Using the Web of Knowledge database, we further assessed whether overcoming the seasonal entrance barrier influences the number of citations a paper receives in subsequent years. We discuss the possibility that the different rejections policies in the two journals, employing desk rejections or not, may explain this discrepancy, and explore a range of alternative hypotheses. 相似文献

This study examined the differences in processing between regular and dyslexic readers in a lexical decision task in different
visual field presentations (left, right, and center). The research utilized behavioral measures that provide information on
accuracy and reaction time and electro-physiological measures that permit the examination of brain activity during cognitive
processing. Two groups of university students, regular and dyslexic readers, were matched on age, gender, intelligence, socioeconomic
status, and handedness. A lexical decision task was used in order to examine the processes during word recognition. Subjects
were required to decide whether a sequence of letters constituted a real word existing in spoken language or whether the stimulus
seen was not an accurate word. For the behavioral measures, it was found that the dyslexics read slower and with more errors
than the regular readers. Moreover, the ERP components appeared later in dyslexics as compared to regular readers in this
task. The performance of the dyslexics improved and even approached that of the regular readers when the stimuli were presented
to the left visual field. Thus, it seems that the dyslexics were relying more on their right hemisphere for linguistic processing,
whereas the regular readers were relying more on their language areas in the left hemisphere. 相似文献

We restrict the discussion of root clustering (exclusion) to rational convex regions. A region in this family is constructed as the intersection of an infinite number of half planes. The root clustering criterion involves the positivity of a set of polynomials with respect to the region's parameter. 相似文献

In this study, we examine the impact and the interplay of general giftedness (G) and excellence in mathematics (EM) on high school students’ mathematical performance associated with translations from graphical to symbolic representations of functions, as reflected in cortical electrical activity (by means of ERP—event-related potentials—methodology). We report on findings of comparative data analysis based on 75 right-handed male high school students (16?–?18 years old) divided into four research groups designed by a combination of EM and G factors. Effects of EM factor appeared at the behavioral and electrophysiological levels. The fifth group of participants included 9 students with extraordinary mathematical abilities (S-MG: super mathematically gifted). We found that in EM participants, the G factor has no impact on the performance associated with translation between representations of the functions. The highest overall electrical activity is found in excelling in mathematics students who are not identified as generally gifted (NG-EM students). This increased electrical activity can be an indicator of increased cognitive load in this group of students. We identified accumulative and unique characteristics of S-MG at the behavioral and electrophysiological levels. We explain the findings by the nature of the tasks used in the study. We argue that a combination of the ERP techniques along with more traditional educational research methods enables obtaining reliable measures on the mental processing involved in learning mathematics and mathematical problem solving. 相似文献

The aim of this study was to identify the specific contribution of executive functions to pre-academic skills (emergent literacy, phonological awareness and orthographic knowledge, and emergent mathematic knowledge) over and above cognitive and linguistic underpinning abilities such as naming, short-term memory and vocabulary. The study was designed to examine the following questions: (1) Are executive functions related to pre-academics skills in general or are they related to specific pre-academic skills? (2) Does the magnitude of the relationship between executive functions and pre-academics skills change with the progress in pre-school age? 54 children between the ages of 5 and 6 years old from 4 different kindergartens participated in the project. A wide range of pre-academic skills, cognitive, linguistic and executive functions tasks were administered. The results demonstrated that executive functions contributed significantly to both emergent literacy and emergent mathematic knowledge. In addition, the current study also suggests that the role of executive functions increases with the growth of child’s pre-academic development. Finally, the strongest contribution of executive functions was found to orthographic knowledge. 相似文献

Using a qualitative research method of life stories, this article examines perceptions among families from Switzerland, Italy, and Israel regarding the media’s role in their process of coping with the murder of close relatives. The findings reveal a duality of attitudes regarding the media found in all three countries examined. The media logic predominant in the experience of victims’ families has a very similar effect, clearly leading to a mediatization of victimhood. 相似文献
