The presented research was conducted in order to investigate the connections between developmental dyslexia and the functioning of verbatim and gist memory traces—assumed in the fuzzy-trace theory. The participants were 71 high school students (33 with dyslexia and 38 without learning difficulties). The modified procedure and multinomial model of Stahl and Klauer (simplified conjoint recognition model) was used to collect and analyze data. Results showed statistically significant differences in four of the model parameters: (a) the probability of verbatim trace recollection upon presentation of orthographically similar stimulus was higher in the control than dyslexia group, (b) the probability of verbatim trace recollection upon presentation of semantically similar stimulus was higher in the control than dyslexia group, (c) the probability of gist trace retrieval upon presentation of semantically similar stimulus was higher in the dyslexia than control group, and (d) the probability of gist trace retrieval upon target stimulus presentation (in the semantic condition) was higher in the control than dyslexia group. The obtained results suggest differences of memory functioning in terms of verbatim and gist trace retrieval between people with and without dyslexia on specific, elementary cognitive processes postulated by the fuzzy-trace theory. These can indicate new approaches in the education of persons with developmental dyslexia, focused on specific impairments and the strengths of their memory functioning. 相似文献

A seven channel polystyrene (PS) microchip has been constructed using a micromilling machine and a high-temperature assembling. Protein A (PA) has been immobilized by a passive sorption on the microchannel walls. Two bioaffinity assays with human immunoglobulin G (hIgG) as a ligand have been carried out. (i) PA as the receptor and fluorescently labeled hIgG (FITC-hIgG) as the ligand, (ii) PA as the receptor with hIgG as the quantified ligand and fluorescently labeled goat anti-human IgG (FITC-gIgG) as the secondary ligand. One incubation step of the assays took only 5 min instead of hours typical for enzyme-linked immunosorbent assay applications. Calibration curves of the dependence of a fluorescence signal on the hIgG concentration in a sample have been obtained in one step due to a parallel arrangement of microchannels. A mathematical model of the PA-FITC-hIgG complex formation in the chip has been developed. The values of the kinetic constant of the PA-FITC-hIgG binding (kon=5.5 m3 mol−1 s−1) and the equilibrium dissociation constant of the formed complex (Kd≤3×10−6 mol m−3) have been obtained by fitting to experimental data. The proposed microchip enables fast evaluation of kinetic and equilibrium constants of ligand-receptor bioaffinity pairs and the ligand quantification. As the use of microfluidic chips for immunoassays is often limited by price, we used procedures and chemicals that allow for an inexpensive construction and operation of the microdevice, e.g., temperature assembling as a fabrication technique, detection via an ordinary digital camera, nonspecific polystyrene as a substrate, passive sorption of biomolecules as an immobilization technique, etc. 相似文献

The leaders of scientific groups appear in the last place (or in the first place) of the authors’ lists of multi-author papers more often than other scientists (group-members). The preferential position of the group leader depends on the branch of science, geographical location and the time point. New tools to study the order of authors were introduced. The validity of assessment of the contributions of particular authors to the paper solely from their ranks in the authors’ lists was challenged. 相似文献

In 1981, Hoover Institution Press published a collection of testimonies of Polish citizens and their children deported to the Soviet Union between 1939 and 1941. War Through Children’s Eyes contained English translations of compositions, interviews, and testimonies from the Polish Government Collection at the Hoover Institution Archives. In the 1980s efforts were underway in Poland to collect similar personal stories of survivors of Soviet deportations, including children’s testimonies. The result was the creation of the Archiwum Wschodnie [Eastern Archive] and the KARTA Center in Warsaw. The archive, legalized after the fall of Communism in 1990, is a major primary source collection dealing with the history of former Polish eastern territories. The paper discusses parts of the Archiwum Wschodnie collection focusing on the testimonies of children deported to the Soviet Union. The trauma of war and displacement is examined through personal stories and testimonies of deportees. 相似文献

In recent years, attention has been focused on investigating the effectiveness of composite memory intervention programs with different age and diagnostics groups. The goal of this study was to measure changes in cognitive lapses by Cognitive Failure Questionnaire (CFQ) in a large trained, dementia free group (Mini-Mental State Examination [MMSE] > 26). The CFQ was administrated to older adults before training (Wave 1), after training (Wave 2), and in a six-month follow-up (Wave 3) to an experimental (N = 77; memory training) and control sample (N = 78, no intervention). Significant changes in subjective cognitive functioning in the experimental group and a plateau curve in the control group were observed. The results indicate support for the efficiency of a large memory-training group in promoting subjective cognitive functioning. 相似文献

This article provides an overview of past and present developments in the digitization of Polish and Polish-American historical newspapers and periodicals. The focus is on the collections held by Polish libraries, including the National Library. The article examines access to and searchability of major digital collections and provides examples of digitized titles. Additionally, the article discusses the importance of including Polish-American newspaper content in the Library of Congress Chronicling America database. 相似文献
